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.

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.
