A polymer door is a door made of a polymer material. A polymer material is a material composed of a compound having a relatively high molecular weight. Many of the natural materials we come into contact with are usually composed of polymer materials such as natural rubber, cotton, and human organs. The same is true for synthetic chemical fibers, plastics and rubber. Generally speaking, a polymer that has been widely used in life and has been formed into an industrialized production scale is a general-purpose polymer material, and is called a functional polymer having a special purpose and function.
Polymer doors have these characteristics
1. Waterproof, moisture proof, soundproof and flame retardant: The polymer wooden door and adjustable door cover have excellent waterproof performance, sound insulation and flame retardant performance through the perfect design and exquisite processing technology.
2. Reliable quality and outstanding advantages: The specially treated polymer door has the characteristics of no deformation, no cracking, no delamination, wear resistance, moisture resistance, environmental protection, flame retardancy and durability, which avoids the traditional door not wearing or not. It is resistant to dirt, easy to deform, easy to crack, easy to delaminate, flammable, prone to mold and surface, and requires many complicated processes such as painting or painting.
The characteristics of the polymer door have the following aspects:
First, it is lighter than metal and glass.
Second, it is easy to process and the processing temperature is low. It can be processed into products of respective shapes by extrusion, injection or the like.
Third, it won't rot or rust.
Fourth, it has high elasticity. It can maintain flexibility over a wide temperature range (-50 to 150 ° C).
Fifth, it has viscoelasticity.
Sixth, it has a buffer damping effect. This feature can be used to prevent noise and vibration.
Seventh, electrical insulation. Polymer compounds are generally electrically insulating materials.
Eighth, it has temperature dependence. Polymer materials are generally affected by temperature.
Solid wood door means that the material used to make the wooden door is natural wood or solid wood composite material (also called solid wood finger joint material or solid wood tooth material) taken from the forest. After drying, cutting, planing, opening, drilling, high-speed milling Form, assembly, grinding, painting and other processes are scientifically processed.
Overview
Solid wood door refers to the door made of the same or similar wood inside and outside the door. The solid wood door contains the original wooden door, and the original wooden door belongs to the solid wood door. The solid wood door has the characteristics of natural environmental protection, no deformation, corrosion resistance, no cracks and heat insulation. At the same time, the solid wood door effectively plays the role of sound insulation because of its good sound absorption.
Solid wood door characteristics: Most wood colors are concentrated in the soft warm color centered on orange; lignin, one of the main chemical components of wood, has a strong absorption of ultraviolet light, and the fine unevenness of the surface of the wood can make Light scattering reduces eye strain and damage. The wood is moderately soft and soft, with a warm touch, good acoustic properties, temperature control, humidity control, etc., and wood processing is easy. All kinds of advantages make wood the most human-friendly wooden door material. Even in the rapid development of science and technology, new materials are emerging one after another, people still have a soft spot for wooden doors. The materials used for wooden doors usually require drying, but the moisture content is about 12%. However, if the solid wood dewatering treatment is not enough, after the wooden door is made, the door body is easily deformed, the joint at the joint is cracked, and the door core plate shrinks and white.
The material of conductive caster is TPR + conductive agent. According to the load capacity. it could be divided into Medium Duty Conductive Caster wheels and heavy duty Conductive Casters. Medium duty has 3inch, 4inch, 5inch. And the load capacity of medium duty is 60-110kg, namely 132-242 pounds. Heavy duty conductive caster has 4inch, 5inch, 6inch, 8inch, and the load capacity range is 80kg-165kg, namely 176-363 pounds. There are many mounting types. For example, fixed/rigid, plate swivel, plate swivel with brake, threaded swivel, threaded swivel with brake, bolt hole swivel, bolt hole swivel with brake and so on. For the bearing we match is 6001 double bearing or annular bearing.
