Melamine board introduction
The substrate of melamine board is particleboard and MDF, composed of base material and surface bonding together, there are two main types of domestic and imported. Because it is through the fire, wear resistant and waterproof soaking treatment, effect similar to composite board.
Melamine board is made of different color or texture of papers into the melamine resin adhesive soak, and then dried to a certain degree of cure, the cracks in the moisture-proof board, particleboard, MDF, plywood, blockboard or other hardboard surface decorative plate formed by hot pressing. In the production process, usually by the number of layers of paper combination, the number of paper depending on the requirement.
The decorative paper bubble in melamine solution, and then through the hot pressing to pressure up. So, moistureproof board which used to make furniture generally called melamine moisture-proof board, melamine formaldehyde resin is a kind of very low formaldehyde solution, which is environmentally friendly, not only will not cause 2 pollution, but will reduce the inside substrate release, this method has been a recognized. But the surface treatment can be divided into good or bad, because the melamine formaldehyde resin solution price is almost 10 times that of other rubber, a lot of people mixed with UF resin in solution, this is not environmental friendly, so the board is divided into melamine and tri poly plate, which is not easy to distinguish.
According to the internal fiber morphology can be divided into two kinds of melamine particle board and melamine density board; The substrate of melamine particle board is made of the wood into particles and wood chips, through the arrangement, hot press and plastic dry; The substrate of the melamine density board labeled timber sawdust by redirecting arrangement, hot pressing, glue dry form. The difference between the two is: the strength of the particle board, strong ability to absorb nails, the density board is relatively weak.

Brief introduction of stainless steel door
The stainless steel door is made of color steel plate shear compression and processing materials, the same as the general view outside, the main material by vacuum plating of stainless steel sheet, the filling is usually wood, foam or honeycomb paper, have a solid feeling when the percussion. The middle is a door flower, the door flower is sandwiched between the two layers of glass, so can play the role of anti-theft door, you can use the mold to produce a variety of door flower pieces. Residential areas, villas, high-end apartments use stainless steel door mostly, generally as the entrance door, to protect the safety of the house property.
The stainless steel door is formed by argon arc welding of stainless steel color plate with the thickness of more than 1.0mm in the direct shear bending type, no pipe skeleton, compact structure and good effect, but the cost is too high so few company produce. The door frame is popular before 2009, with a stainless steel rectangular tube welded frame covered with a layer of 0.8mm stainless steel plate and skeleton spot welding in the outside, middle hollow decorative flowers, embroidered with double glass, and the appearance is beautiful.

Fire door sealing requirements
China National Standard for the size of the gap of the fire rated steel doors between the gaps is clear:, the fan and the door frame of the metal fire door shall not be less than 10mm, the two sides of the gap between the door and the door frame should not be greater than 4mm. After the fire door is closed, the gap can not be too large, otherwise it is difficult to ensure the sealing performance of the fire door, it is difficult to reflect the fire and smoke spread under the conditions of fire.Therefore, the installation of the gap width of fire doors must be strictly controlled. According to the standard specification for installation, it can guarantee the effect of the fire rated wood doors in a certain extent, consumers must supervise in construction employment site, to prevent shoddy problem, so the fire door will not cause casualties in the fire.

The installation method of the fire door
Fire door according to the material is divided into fire steel door and fire proof wooden door. There are some differences in the installation methods of the two kinds of fire doors, but also a little different from the fire protection level, we must pay attention to the details of the installation.
First, while in the installation, the size of the fire rated wood doors frame should be less than the entrance to the 20mm, the lower part of the door frame should under the ground to 20mm. Door frame should be fixed firmly with the wall, vertical angle. Vertical frame and support frame should be paid attention to with straight angle, avoid saw. The two sides of the fixed point of the door frame is not less than 3, the best distance is not greater than 800mm.
Secondly, in the installation process of steel fire doors, considering the bending deformation of the frame, used to support in the frame width direction with the wood brace, the lower part of the door frame should under the ground to 20mm, and then weld the frame and the wall of the embedded parts. Then the door open in the corner of the wall, pouring cement, sand, perlite (1:2:5) concrete, can be use after concrete is solidified.
