Knowledge Of WPC Door

1. How to measure the door opening?
The height of the door opening is based on the lowest, the width is based on the narrowest, and the wall thickness is based on the thickest.
2. How to reduce the size?
Generally speaking, the height is reduced by 4 cm, and the width is reduced by 8 cm.
3. What is the process and production process of the WPC door?
Using wood powder and resin powder as the main raw materials, adding a certain amount of additives (stabilizers, plasticizers, foaming agents, modifiers, lubricants, etc.), after full mixing and fusion, through the use of molding technology, in One-time extrusion molding under high temperature and high pressure.
4. How to deal with the surface of the WPC door?
The surface can be painted or heat transfer printing
5. What is the thermal transfer process?
First of all, we need to understand a material called thermal transfer film, which consists of three layers of materials: base glue layer, color film layer and surface UV layer. The thermal transfer printing process is to cover the transfer film on the surface of the material for heating and pressure. When the base glue layer is melted, the color film will be firmly combined with the material, and there will never be peeling and peeling. The UV layer has the function of strengthening and anti-ultraviolet. Most of the paint-free doors are made of PVC film. The surface is treated by hot-press bonding or vacuum blistering. The PVC film will age and fall off after a long time, or the air will enter and use it. There are air bubbles between the door leaf and the PVC film.
6. What is the structure of WPC door?
The WPC door adopts an integrated cavity structure, which not only enhances the strength and stability of the door body but also endows the door with the function of sound insulation and heat preservation, which greatly reduces the consumption of raw materials. of.
7. How many cavities are there in the WPC door?
Each cavity is about 4 cm wide, and the standard 60, 70, 80, and 90 door cavity numbers are 12, 14, 16, and 18, respectively.
8. What are the thickness of the door panel and the thickness of the single wall of the WPC door?
The thickness of the base material door leaf is about 43mm, the thickness of the finished door is 42mm, the single wall thickness of the ordinary door leaf is 4mm, and the single wall thickness of the European door leaf is 6mm’.
9. What is the nail-holding power of the WPC door?
The holding force of a single WPC door screw can reach 350 kg, and it can be used repeatedly 60 times.
Why is WPC door waterproof?
The water absorption of the wood itself is as high as more than 10%, but after the surface treatment of the wood powder, a layer of the polymer film is formed on the surface. The test results show that the water absorption of the wood-plastic material is less than 2%, and it has a certain waterproof performance.
10. Why environmental protection?
From raw materials to production to secondary surface treatment, WPC door does not require adhesives such as glue and does not contain toxic and harmful substances such as formaldehyde and toluene, so it is a green and healthy product.
11. How to install a WPC door?
WPC door adopts a buckle-type quick-installation structure, linking the door cover with L-shaped metal parts, fixing the whole door cover on the wall with the wooden keel or foam glue, and installing hinges and locks according to the normal procedure, which is very convenient.
12. What hinges are used for installation? How many?
The hinges use ordinary mother-in-law hinges, and there are three doors in each set. The upper hinge is 16 cm from the top of the door leaf, the middle hinge is 60 cm from the top of the door leaf, and the lower hinge is 20 cm from the bottom of the door leaf.
13. What kind of locks can be installed?
General spherical locks, handle locks, combination locks, and electronic induction locks on the market can all be used.
14. What is the amount of formaldehyde released?
The national formaldehyde emission standard has three levels: E2 level ≤ 5mg/L, E1 level ≤ 1.5mg/L, and E2 level ≤ 0.5mg/L. The formaldehyde emission of emerging wood-plastic products is 0.2 mg/L, which is lower than the highest standard E0 level.
15. Why can it be flame retardant?
This is related to the molecular structure of the resin powder (polyvinyl chloride) in the material. The chlorine element with a high content is relatively inert and has the function of self-extinguishing when away from fire. Usually, the oxygen index of this material is as high as 35 or more, and the fire protection level can reach B1. .
16. How heavy is the door?
The standard size of a normal transfer door leaf is about 20 kg, and the weight of a European-style painted door leaf is about 25 kg.
17. What size can it be?
There is no limit to the length direction of the door leaf, which greatly reduces the cost of some ultra-high size doors; the width of the door leaf is 600mm, 635mm, 680mm, 700mm, 735mm, 780mm, 800mm, 835mm, 880mm, 900mm.
18. Why can't the door leaf be as wide as the reported width of the composite door?
Different from composite doors, WPC door is completely molded, mechanized, and automated. Each specification requires a mold. The 10 different widths designed by the company basically cover all door opening sizes in the country, from 680mm to 1000mm. Door openings can be satisfied. The company's door cover and line design adopts a telescopic cover structure, which can be adjusted on-site according to the size of the door opening, which is very convenient. The width of the door cover is 100mm, 140mm, 180mm, 220mm, 260mm, and 300mm. It meets the requirements of wall thickness from 100mm to 300 mm. For the door cover of the ultra-wide wall (≥300MM), an extra-wide connection component design is added, and the combination of the component and the fixed-size door cover meets the supporting needs of the ultra-wide wall: the design of the door cover line is compatible with the decoration The two functions of adjustment and adjustment, the width of the door cover can be adjusted by using the expansion and contraction of the extended bayonet to adapt to some non-standard thickness walls.
19. How many colors are there for the door?
There are currently 10 colors for transfer printing and 6 colors for baking varnish
20. How many lines are there?
6, 7, 8 cm three kinds
21. How to repair the de-molding or scratches on the surface of the door?
There are several situations for demoulding: for thin line type, you can use a color correction pen to repair the color; for a slightly larger area, you can use 502 glue to apply on the transfer film, and stick the transfer film to the surface of the door for repair; No matter how big it is, it needs to be repaired with a portable hot stamping machine. For scratches or bumps, you can fill them with wood powder mixed with 502 glue, smooth them with gauze, and then use a hot stamping machine to repair the color.
22. Compared with other types of doors, what are the advantages of WPC door?

25. What are the types and characteristics of interior doors?
Solid wood door: The whole door is completely processed with solid wood. The more popular materials nowadays are roughly elm, Korean pine, barn wood, catalpa, ash, beech, and so on. The door is characterized by clear wood grain and a strong sense of integrity and three-dimensionality. Its price varies according to different materials. But its biggest shortcoming is that it is easy to deform and crack, which is caused by the characteristics of the wood itself, and the most advanced technology in the world cannot completely solve it.
Solid wood composite door: Solid wood composite door is currently the best-selling and most promising variety in the market. It is a craft introduced from Germany to China, which is the crystallization of combining traditional Chinese solid wood doors with European composite doors. The internal material is filled with solid wood, the wooden door panel is made of a 5cm medium-density board, the edge is closed with solid wood board, and the exterior is processed with solid wood lines. Its advantages are that it is not easy to crack and deform, and the styles are diverse, which can suit different styles of families. furnish. It has a strong sense of solid wood and feels. Improve your personal taste.
High-grade solid wood composite door: the door core is mostly glued wood, solid core. The surface is solid wood veneer with advanced painting technology and high grade. Features: smooth feel, soft color, more environmentally friendly, anti-deformation, durable. It is also called a solid wood craft door on the market, and the price is around 1200-2300 yuan.
Low-grade solid wood composite door: the door core is a solid wood frame, with a layer of density board on each side, and there are two ways of surface treatment:
1. Paint spraying: Paste a layer of density board on both sides, and then spray paint after pasting wood grain paper on the outside of the density board or spray paint directly on the density board. The filler in the middle is various.
2. Paint-free: Paste wood grain paper or PVC on the density board, use pine or fir to build the keel, paste a layer of density board on each side, and then paste a paint-free finish on the outside of the density board, with various fillers in the middle.
The price of low-grade solid wood composite doors is 600-900 yuan. The disadvantage is that it is easy to be damaged, and it is afraid of water. Due to the use of density boards, it is not easy to guarantee environmental protection.
Molded WPC hollow doors: Molded wooden doors are mechanically pressed from two 3cm or 5cm MDF high-density fiber molded door panels with modeling and simulated wood grain. Since the inside of the door panel is hollow, the natural sound insulation effect is worse than that of solid wood doors, and it cannot be wet. Its advantage is that it is not easy to crack and deform, but its disadvantage is that it is not high-grade and not suitable for tasteful home decoration.
Surface treatment: spray paint and PVC molded door
Advantages: Good anti-deformation performance and economical price. Disadvantages: MDF pressing is not good for environmental protection, and the hollow sound insulation effect is not good.
Steel-wood door: an interior door extended from the anti-theft door. Its craftsmanship is similar to that of the anti-theft door, but the main frame is made of wood with honeycomb filling in the middle. It is characterized by environmental protection, easy cleaning, and low price. Disadvantages: poor texture, less shape, and inconvenient maintenance. The price is between 600-750.
