Problem

How does the floor work?

       First, the joints from the drums

       A, the floor surface of the water: the installation process, it is inevitable that sometimes the glue is not completely fill the joints. If the towing towing dripping water will cause the floor surface of the water and from the suture into the less seam, the floor substrate will absorb moisture, resulting in local expansion and has a small bubble phenomenon. In this case, the surface of the floor is partially bulged;

       B, the bottom of the floor into the water from the drum: the surface phenomenon for the seams bulging shape is more uniform, from the water near the place more severe, far more and more peaceful place. Where there are such problems are: near the bathroom, kitchen, heating pipes, air conditioning, condensate drain, windows and so on. Such as flooding a long time, the surface phenomenon is not obvious, you can open the floor to check whether there is a watermark to determine the reasons;

       C, the floor short seam from the drum: the performance of the long floor of each short side of the floor are from the drum, usually caused by too much moisture on the ground. The higher the drums, the greater the ground moisture.

       Maintenance program: replace the floor.

       Second, the floor from the arch

       Surface phenomena are stepped up to have a sense of suspension, individual places will be more serious.

       A, expansion joints reserved for the floor from the arch;

       B, the room through the shop: more than two rooms in the installation of the floor when the door do not install the buckle, in the moisture, the greater the two rooms when the floor of the horizontal extension of the floor, causing the room at the door of each other involved, so that the floor from the arch;

       C, expansion joints were nailed to death or plaster, putty, etc. to fill, so that the floor can not stretch, resulting in the floor from the arch;

       D, the installation process, there are foreign body to stay in the floor, resulting in arch;

       E, floor under the grass from the arch, such as the installation of the floor before the original solid wood flooring, after the floor after the original floor damp from the arch, resulting in the floor was arched;

       Repair the program: from the skirting board, once again set the expansion joints; in the room and the room connection to install the buckle; re-install the baseboard, clean up the plaster, putty and other reserved expansion joints; from the floor, Out of the floor, the ground treatment is flat, dry and then pave the floor again.

       Third, the floor cracks

       A, uneven ground: the ground is not smooth in the case of paving the floor, after a period of time, the floor between the glue off the gap;

       B, less sizing: the floor in the winter, there is heating baking, air drying, floor plane contraction, seams glue shortage, strength is not enough, so that the floor open plastic cracks;

       C, the side of the weight: the need to repair the floor parallel to the direction of the heavy pressure, so that the floor can not be free to shrink, resulting in cracks; this room will appear in the summer arch phenomenon, and winter heating when there will be cracks phenomenon;

       Maintenance program: remove the floor, the ground treatment is flat, dry and then paved; according to the size of the crack, decided to fill wax, re-irrigation; with special tools fixed or reload; remove heavy objects, re-irrigation fixed.

       Fourth, the surface defects

       A, corner: the floor in the handling process bumps, the construction staff in the construction process did not pay attention to or after the construction of clean up the glue when the shoveling, so that the corner of the corner of the phenomenon;

       B, the surface off: after the construction, the weapon or heavy objects fell to the ground floor, so that the floor is affected; or floor processing, the surface and the substrate is not gluing good, after a period of time, the surface and the substrate degumming;

       C, scratches: the customer on the floor when the furniture or heavy objects, the floor and the items mixed with nails or sand and other debris, drag on the floor caused by damage to the floor wear layer or obvious scratches;

       Repair program: wax block repair or replace the floor. First, the joints from the drums

       A, the floor surface of the water: the installation process, it is inevitable that sometimes the glue is not completely fill the joints. If the towing towing dripping water will cause the floor surface of the water and from the suture into the less seam, the floor substrate will absorb moisture, resulting in local expansion and has a small bubble phenomenon. In this case, the surface of the floor is partially bulged;

       B, the bottom of the floor into the water from the drum: the surface phenomenon for the seams bulging shape is more uniform, from the water near the place more severe, far more and more peaceful place. Where there are such problems are: near the bathroom, kitchen, heating pipes, air conditioning, condensate drain, windows and so on. Such as flooding a long time, the surface phenomenon is not obvious, you can open the floor to check whether there is a watermark to determine the reasons;

       C, the floor short seam from the drum: the performance of the long floor of each short side of the floor are from the drum, usually caused by too much moisture on the ground. The higher the drums, the greater the ground moisture.

       Maintenance program: replace the floor.

       Second, the floor from the arch

       Surface phenomena are stepped up to have a sense of suspension, individual places will be more serious.

       A, expansion joints reserved for the floor from the arch;

       B, the room through the shop: more than two rooms in the installation of the floor when the door do not install the buckle, in the moisture, the greater the two rooms when the floor of the horizontal extension of the floor, causing the room at the door of each other involved, so that the floor from the arch;

       C, expansion joints were nailed to death or plaster, putty, etc. to fill, so that the floor can not stretch, resulting in the floor from the arch;

       D, the installation process, there are foreign body to stay in the floor, resulting in arch;

       E, floor under the grass from the arch, such as the installation of the floor before the original solid wood flooring, after the floor after the original floor damp from the arch, resulting in the floor was arched;

       Repair program: wax block repair or replace the floor.


What should I pay attention to?

        Installation Precautions:

        1, request advance 24 delivery, so that the floor to adapt to the indoor humidity and temperature.

        2, to ensure that the indoor formation, clean, dust and rugged. Such as the election space height difference of 2 cm must be flattened, the wall should be flat to avoid the baseboard display seam.

        3, shop before the tide layer must be determined on the ground dry, smooth, geothermal floor must be used for geothermal ground.

        4, between the floor and the wall to leave 8 - 10mm gap to prevent the tide expansion

        5, each room from a piece of the plate, different rooms at the door with metal buckle separated. If the room area is large, then every 8 to 10 meters to ease the impact of thermal expansion and contraction.

        6, the floor should be slightly higher than the kitchen and toilet to avoid damp deformation.

        7, geothermal floor, first in the wall drilling, nail spacing of not more than half a meter, otherwise the base line is not strong.

Finally, after the completion of the pavement to let the floor dry for more than 24 hours, so that the glue dry and breathable, during the period do not force stampede or put heavy objects in the above.


What are the common problems with the floor?

       1. The reason for the lack of drums is due to the fact that the number of blankets and keels, the number of slabs and floor nails is small or nailed, and sometimes due to changes in the moisture content of the sheet caused by shrinkage or glue failure Cause Therefore, strict inspection of sheet moisture content, adhesive and other quality of the process is particularly important. After passing the inspection to use, the installation of nails should not be too little.

       2. The main cause of uneven surface is uneven grass or floor deformation caused by drums. In the construction, the application of the level of the keel surface leveling, if the uneven should be adjusted wood. The keel should be ventilated. Board edge should be set aside for 10 mm ventilation. Insulation insulation material must be dry to prevent the board from damp after the drum. Wood floor surface roughness error should be within 1 mm.

       3. The reasons for the uneven patchwork In addition to the construction of non-standard, the width of the plate size error and poor processing quality is also an important reason.

       4. The main cause of local Alice in addition to the board damp deformation, there are small plaster or patchwork seamless, the use of water pipes and other water leakage caused by wet floor. After the floor pavement, brushing the floor paint should be complete film, daily use to prevent water into the lower part of the floor, to clean up the surface layer of water.

       5. corner: the floor in the handling process of bumps, the construction staff in the construction process did not pay attention or after the construction of clean up the glue when the shovel, so that the corners of the corner corners of the phenomenon;

       6. Surface off: After the construction, the weapon or heavy objects fall to the ground floor, so that the floor is affected; or floor processing, the surface and the substrate is not gluing good, after a period of time, the surface and the substrate degumming;

       7. Scratches: the customer on the floor when the furniture or heavy objects, the floor and the items are mixed with nails or sand and other debris, drag on the floor caused by damage to the floor wear layer or obvious scratches.


How to maintain the floor substrate?

       1, to keep the indoor ventilation and dry environment

       Regularly maintain indoor ventilation, both in the floor of the chemical substances as far as possible volatilization, outdoors, but also can make the indoor moist air and outdoor exchange. Especially in the long-term no living, maintenance of the case, the indoor ventilation is more important. Common practice is: often open the windows or doors, so that air convection, or the use of air conditioning system and ventilation system, thus creating indoor dry and clean environment.

       2, to avoid sun exposure and rain wet

       Some houses sunshine or rainwater can enter the indoor area directly from the window, which will be harmful to the bamboo flooring. Sunshine will accelerate the aging of the paint and glue, but also cause the floor of the shrinkage and cracking. After the rain is wet, the bamboo absorbs water and causes swelling and deformation. So in daily use to be particularly attention.

       3, to avoid damage to the floor surface

       The floor of the paint is both the floor of the decorative layer, but also the protective layer of the floor, therefore, should avoid the impact of hard objects, sharp scratches, metal friction, chemicals can not be stored in the room. In addition, the indoor furniture in the handling, moving should be careful, furniture, feet should be put rubber and so on. Public places, should be covered in the main channel carpet and so on.

       4, the correct clean care

       In the daily use of the process, should always clean the floor, keep the ground clean and sanitary. When cleaning, you can use a clean broom to sweep the dust and debris, and then wipe dry water wipes manual wipe, such as the area is too large, you can wash the cloth mop, and then hang up drip drip, used Drag the ground. Must not be washed with water, can not use wet cloth or mop to clean up. Usually if there is water splashing on the ground, you should immediately dry with a dry cloth. If conditions permit, you can also take a layer of floor wax to help strengthen the protection of the floor. If the paint is damaged, you can use their own ordinary varnish or ask manufacturers to repair.


How to judge the quality of the floor substrate?

       1, than the color: by observing the floor at the mouth of the substrate color, you can identify the quality of the substrate substrate quality. High-quality flooring substrate color should show the natural pine, poplar color; inferior flooring substrate due to the production process did not use high-quality logs and use Zamu, shrubs; or in order to reduce costs without veneer, so poor quality The color of the material will show dark brown, after comparison will be able to clearly see.

       2, look at the fiber: by observing the substrate cutting at the substrate wood fiber, you can identify the quality of the substrate substrate quality. High-quality flooring substrate cutting can be seen evenly, stout, arranged dense wood fiber, fiber color showed natural wood color; poor quality substrate cutting wood fiber showed a significant uneven thickness, and even significant Of the sheet-like objects, fiber color is different, there are dark, light-colored, and even can see dark brown spots.

       3, smell the smell: by smell the smell of the substrate substrate interface can also identify the quality of the substrate substrate quality, good floor exudes a fresh woody flavor, not pungent, not dazzling; poor floor fragrance is too rich, pungent, Even the situation of tears.

       4, check the cross-section: from the edge of the internal substrate, high-density laminate flooring looks very detailed. Good to strengthen the floor substrate feels very smooth, plain, no grainy, poor feel very rough, cut the wood floor, the good distribution of the cross section of the floor is very uniform, do not see a clear distribution.


How to buy medium density fiberboard?

       With the current improvement of people's living standards, people's health awareness, environmental awareness, aesthetic awareness continues to increase, MDF has been welcomed by the people, is widely used in life. Today, Xiao Bian to tell you to talk about, buy some of the skills of MDF. Usually we will from two aspects to identify the density board is good or bad.

       First, environmental protection

       According to the standard, MDF according to its free formaldehyde content can be divided into E0 level, E1 level, E2 level, CARB P2 level. E2 grade formaldehyde emission is ≤5mg / L; E1 grade formaldehyde emission is ≤1.5mg / L, can be used directly for interior decoration; E0 grade formaldehyde emission is ≤0.5mg / L. CARB P2 grade formaldehyde emission ≤ 0.3mg / L. Among them, E0, E1, E2 grade refers to the domestic standards, CARB P2 refers to the European and American standards. Consumers in the purchase of MDF, should try to buy low-formaldehyde emission of goods, such goods more secure.

       Blue aperture between 0.27-0.98 nm, was crystal arrangement. At the same time with weak electricity, formaldehyde, ammonia, benzene, toluene, xylene molecular diameter are between 0.4-0.62 nm, and are polar molecules, with preferential adsorption formaldehyde, benzene, TVOC and other harmful gases to achieve purification Indoor air effect.

       Second, the quality

       Surface cleanliness: surface cleanliness of the MDF surface should be no obvious particles. Particles are caused by the impurity into the process of pressing, not only affect the appearance, but also easy to peel off the paint film.

       Surface smoothness: hand touch the surface should have a smooth feeling, such as feeling more astringent Note processing is not in place.

       Surface flatness: MDF surface should be smooth and smooth, such as from the side to see the surface is not smooth, then the material or paint process problems.

       Overall flexibility: hard board must be inferior products.

       Strength: high-quality MDF strength is good, with both hands picked up the density board at one end of tremors a few times, if the board is very strong, the quality of this board is better; poor density board in the process of tremor even break.

       Appearance: high-quality MDF fiber length less than 2mm, uniform length, the shape of fine, medium density board surface is not soft, depression, drum and other defects, if these defects, the quality is low; product color distinction, according to Different materials, the color of poplar material yellowish, in addition to the process of washing the peeling of the loose and the color of the eucalyptus yellowish white, white, the general plate partial black.


What is the reason for the thickness plate thickness deviation?

       I believe that whether the MDF manufacturers or MDF dealers often receive customers such feedback: customers buy the actual thickness of the plate with the thickness of their requirements are not the same. Normally, the normal thickness deviation of the plate is ± 0.2mm. Of course, because the plate production process for a variety of reasons leading to the thickness of the finished product quality problems. What are the main causes of density plate thickness deviation?

       1, raw materials pavement uneven

       MDF in the production process, the uniformity of raw materials pavement is one of the important factors affecting the thickness deviation of finished products. If there is a weight uneven or left and right pavement uneven, it will lead to other layers of slab thickness deviation, the emergence of "wedge plate" and ultra-thin, thin plate.

       2, hot plate deformation

       China's current production of the majority of manufacturers density plate thickness deviation is due to deformation caused by hot plate. There are two main reasons for the deformation of hot plate: preheating heating uneven, the temperature rises too fast; in the production process of missing slab, light slab, short slab and so on.

       3, slab in the hot plate in the position of asymmetry

       When the slab in the hot plate position is not symmetrical, the hot plate in the pressure process can not always maintain a horizontal state, resulting in thickness deviation.

       4, the hydraulic system position control is not accurate

       Xiaobian in this simple with you to describe the working principle of multi-layer press: multi-layer presses are generally using multiple cylinders at the same time work, and some press all the cylinders are directly connected with the same pressure pipe, their The pressure is the same at any time, can not be individually changed and adjusted, it can not overcome the uneven pavement, slab in the pressure plate position asymmetry and other reasons caused by the thickness deviation.
