How to tell the difference between good and bad automatic doors? How to identify the quality of inte

Door machine ** more than 2500-3000 yuan (excluding glass and installation costs), less than 2000 yuan basically can't be used.

1. Weigh the weight (whether the weight is appropriate):

A good wooden door should not be too light. Compared with several wooden doors of the same specification and the same surface layer of timber, it is difficult to say that the wooden door with too light weight is a high-quality wooden door, because most of the core materials are relatively soft (such as poplar), and the pipes and pores in the wood are relatively large; Or maybe there is too little core material inside, which makes the wooden door not strong enough. The strength and impact resistance of this kind of wooden door are relatively poor, and the sound insulation effect is not good.

2. Look at the appearance (lacquer and veneer):

The paint surface of high-quality wooden doors is full and smooth, rich and natural, the paint film is transparent, the texture of the surface materials is clear and realistic, and the physical properties of the appearance are clear at a glance. The inferior wooden door paint film is shriveled and obscure, and there are many exposed paint, bubbling, pinholes, ripples, particles, etc., and the paint film has poor transparency, the surface texture is blurred, and the appearance of the wood is obscure and difficult to distinguish. The reason why inferior wooden doors are so, on the one hand, is because the paint quality selected by the manufacturer is poor, and the process and equipment are not up to standard; On the other hand, the veneer used has many defects, so the transparency of the coating is deliberately reduced to cover up the defects such as dead joints, holes, decay, discoloration, cracks, and indentations on the surface.

3. Look at the veneer or solid wood splicing:

The veneer or solid wood splicing of high-quality wooden doors is processed more finely, and no traces of combination can be seen. The veneer or solid wood processing of inferior wooden doors is rougher, the splicing is more obvious, and even cracking and dislocation occur.

4. Look at the flatness of the wooden door

High-quality wooden doors have strict requirements for material selection, process control and factory inspection, and the surface of the finished wooden door is smooth and straight, and the appearance is perfect after installation. Inferior wooden doors have very low requirements for materials, processes and inspections, and the warping degree of the finished wooden door is large, and it can be clearly observed that the wooden door and the door frame can not be aligned after installation.

The first trick: knock and weigh the wooden door:

According to experts, to identify the quality of wooden doors, the first thing is to knock and weigh. The filling inside the door is generally divided into solid and partially solid, and the solid filling must be heavy, and it is expensive; And some of the solid is relatively light, and ** is also relatively cheap.

However, there are some black-hearted merchants who use scraps as fillers, and this kind of wooden door is environmentally friendly. So as a consumer, you should develop the habit of buying branded products.

The second trick: check the seal:

The "seal" is directly related to the tightness of the door. The sealing strip is "hidden" in the contact part between the door sleeve and the door leaf, which is relatively soft to the touch.

Regular enterprises will add sealing strips to avoid the problem of a seam after closing. If the sealing is not tight, the wood is easy to release formaldehyde, and the environmental protection is not up to standard.

The third trick: the door cover is equally important:

The material and quality of the door cover are also the key to environmental protection. Some businesses use different materials for door sets and door leaves, and solid wood door leaves do not mean that solid wood door covers will be used.

If the solid wood door is made of MDF, because it does not contain wood fiber, it is easy to foam when exposed to water, which will cause the door frame to deform. Therefore, when purchasing, it is necessary to ask whether the door sleeve and door leaf are the same material.

The fourth trick: understand the environmental protection indicators:

Formaldehyde emission Soluble lead 90mg kg, soluble cadmium 75mg kg, soluble chromium 60mg kg, etc. Wooden doors with the characteristics of light weight, good rigidity, waterproof, anti-corrosion, insect-proof, sound insulation, heat preservation, flame retardant and other characteristics should be the first choice.

First, look at the paint surface, a good paint surface is smooth and there are no pittings, and see whether the wood grain is clear and natural. (Most important!) There is no good paint surface core material, no matter how good it is).

Second, look at the weight of the wooden door, many people think that the heavier the door is to buy the better, this is a misunderstanding, you have to ask about its material for example: you buy a solid wood craft door, its core material is generally fir wood, you must know that fir is a very light wood, if it is too heavy, it means that it contains more MDF. To figure out the wood, look at the weight.

Three, knock to see if there is a muffled sound. If there is, it is not true. In this case, if the door is still in the middle, don't buy it.

If the weight of the door is okay, check with the buyer what the solidity is. (If the solid wood craft door is made of fir finger jointing board, that is, fir laminated timber, it cannot be 100% solid.) Generally, it is very good to reach 75%, because in order to prevent the deformation of the wood, there must be a gap to facilitate the thermal expansion and contraction of the wood.

He tells you that 100% solid will definitely fool you, and of course there are 100% solid ones such as woodworking boards).

Fourth, look at the buckle line and carving, a good wooden door buckle line and carving are made of logs, you can see the wood grain from above, and the wood grain is natural, the poor is carved with MDF, generally no wood grain. Some open lacquer buckles are carved first, and there are also wood grains, but some are worked by people, which is unnatural. A small carving, solid wood and MDF will be one or two hundred different in cost.

The first two items are suitable for all wooden doors, and the latter two are mainly for solid wood craft doors.

To identify the quality of the wooden door, the first is to knock and weigh the method, the filling in the door is generally divided into solid and partially solid, the solid filling must be heavy, and it is expensive, and the part of the solid is relatively light, and the relatively cheap. However, there are also some black-hearted merchants who use some scraps as fillers to increase weight, so as consumers, you still have to develop the habit of buying branded products.

The second way to identify this is to look at the "seal". The "seal" is directly related to the tightness of the door. The sealing strip is "hidden" in the contact part between the door sleeve and the door leaf, which is relatively soft to the touch.

Regular enterprises will add sealing strips, so as to avoid the problem of always having a seam after closing.

Decoration rookie must-see wooden door purchase three elements.

The third is the material of the door cover. The reporter learned that most of the complaints about wooden doors are mainly due to problems with the door cover. The essence of the problem is that businesses do not necessarily use the same material for the door sleeve and the door leaf, and the solid wood door leaf does not mean that the solid wood door cover will be used.

If the solid wood door is made of MDF, because it does not contain wood fiber, it is easy to foam when exposed to water, which will cause the door frame to deform, so it is best to ask the merchant whether the door cover and door leaf are the same material when buying.

Mainly depends on the wood used, the so-called quality mainly depends on the ability to resist deformation, generally divided into solid wood doors, solid wood composite doors and molded doors, as well as relief doors, etc., solid wood doors are the heaviest, because they are solid wood, so they will be deformed, but magnificent.

The wood-based panels are poor, and the logs are good;

The hollow one is poor, the solid wood is good;

The color mixing of the paint is poor, and the transparent paint is good;

**Cheap poor, expensive good;

That's probably it.

Interior doors are mainly divided into paint-free interior doors, lacquered interior doors, steel-wood interior doors, solid wood interior doors, wood-plastic interior doors, solid wood composite doors, and ecological interior doors.

Choose interior doors.

1. It depends on the style and color, so the first thing to consider when choosing a wooden door is the harmonious matching of the style and color of the wooden door with the style of the living room. The decoration style is stable and plain, so choose a generous and concise style; Lively and bright, we choose light and elegant, want to match; Classical comfort is decorated with heavy elegance. In short, it is recommended to choose a style that is similar to each other.

2. Hand touch and side view. Stroke the frame, panel, and corner of the door with your hands, requiring no scratching, soft and delicate, and then stand on the side of the door to see if the paint surface of the door panel has uneven waves. Basically, you can know whether the workmanship is qualified by these two clicks.

3. Inspection materials and relevant qualification certificates of manufacturers. By checking whether the relevant qualification certification of the manufacturer is complete and true against the relevant industry standards, the product structure is measured.

Finally, before installation, pay attention to the final check by looking at the internal materials of the door keyhole.

1.Since I have been engaged in decoration, I have been dealing with the problem of door deformation, from 97 years later, basically to the construction wood factory, door processing factory, according to the thickness of the door design, the style, the size of the wood outside the door, the position of the lock wood, etc., the door blank made.

2.On the basis of the blank door, the panel, etc., should be treated equally on both sides!

3.After pasting the panel, close the mouth with a solid wood closure strip and then apply paint!

4.According to the practice, there is no deformation, and I have done tens of millions of projects! If you can, you'd better do it!

5.There are *** in the finished door, but now there are a considerable part of the quality is not impressive, it is very good when you buy it, but it is quickly deformed and cannot be repaired, you must have the ability to identify! Remember.

6.Try not to use the door of the leather at home, and use a decorative board, because the leather will be broken and cannot be repaired when touched!

7.During the construction of the door sleeve, it is best to make a wooden dragon skeleton, and then use two layers of nine plywood - decorative board, try not to do it with a large core board!

I hope the above suggestions will help you!
