Q:Jilin forest workers Lushui River plate quality how?

Dushuihe particleboard four advantages of the achievements of the high quality products: First, the advantages of resources and raw materials. Jilin forest workers have 1.39 million hectares of forest resources, the northern timber growth cycle is long, good material, very suitable for the production of high-quality particleboard. Second, advanced equipment. Dushuihe particleboard production line equipment from Germany, Finland and other Western forestry developed countries to introduce. Third, talent advantage. Jilin forest workers are old state-owned enterprises, with a large number of knowledge-rich, skilled technical and technical personnel. Fourth, green environmental advantages. As early as 1999 Jilin Forest Industry Co., Ltd. production of "Lushui River" brand particleboard to achieve the E1-class environmental standards, a full year than China's national standards in 2002 as early as 2 to 3 years. In 2002, when other enterprises in order to adapt to the national standard and equipment renovation, Jilin Forest Industry Co., Ltd. can make more time for new product upgrades R & D, which for them to win more market development space The In 2004, Jilin Forest Industry Co., Ltd. took the lead in the development of the E0-class particleboard, the product to fill the domestic blank.

Q:What are the classification of timber for construction?

uilding timber is divided into: logs, square materials, sheet, glue material. Good understanding of logs. Square wood is machined into rectangular or square, and the aspect ratio is less than 3. Thickness ratio greater than or equal to 3 for the plate. Plywood is a man-made material, is the use of various materials using the corresponding production process manufacturing. Logs, square wood is mainly used for columns, beams, roof trusses and so on. Plate, plastic material used for wall, ceiling and other decorative parts.

Q:Buy plate three errors is what?

At present, consumers themselves have many misunderstandings about the purchase of plates: ????"Trimming smooth and smooth plate must be good." This is not true. Perennial deal with the plate of a home improvement company boss said that the more such a plate of consumers more careful, trimming is generated when the machine sawing, good plate generally do not need "re-processing", often a lot of stubble child. But the quality of the plate because of its internal is empty, black core, so the processor will "deliberately dress up" it, in the trimming and then paste a "nice" wood, and polished smooth neat, to confuse the consumer , So you must not use this as a standard to measure what is good or bad. ????"3a is the best." Some readers reflect that they are doing the decoration in order to no problem, only selected marked "3a level" of the plate, the result is still a problem. In fact, the national standard is not "3a", but the business or business personal behavior, can not guarantee its quality. Currently on the market has not allowed the words, the detection of qualified wood will be marked "excellent goods", "first-class goods" and "qualified products." ????"The heavier the better plate". This view is absolutely incorrect, the insider to buy a look at the degree of drying, two see splicing. Good dryness of the plate is relatively light, and there will be no cracks, very smooth. For outsiders of consumers, the safest way is to reliable building materials market, buy some well-known brands of plates. In order to prevent some of the counterfeit products on the market, you must see whether the purchase of a national authority issued by the test report once the problem is also well documented.

Q:What kind of domestic brand plate frame good?

Eyes are their own, love the eyes is very necessary, especially after myopia, do not just say where to see where the glasses discount quickly ran with glasses, but the quality of the glasses off the eye damage is very large , The importance of the frame can not be ignored. So when the glasses with the choice of good glasses glasses is the most critical. Now the glasses are better brands are the island, Daming, the United States pupil - Johnson & Johnson, Hai Chang, snow and so on, these are the brand network MAIGOO 2017 top ten glasses brand, you can go to see the above details. Or that sentence, the eyes are their own, not for a moment of cheap on the casual with the pair of glasses, be sure to choose a good brand.

Q:These two days is very contradictory, before the decoration and the former contract with the master said the use of the plate is E1 level, the plate is really pulled, but her husband saw a lot of scar on the plate above the wood scar, said the decoration master Cheat him, then simply to the plate company to see, know it is true, but I heard there is a E0 level, and now immediately asked the master replaced by this level

You can first know: plate environmental protection level E1 and E0 distinction so you can probably judge

Q:How much is the quartz stone plate? What is the specification?

See how much you want, and wholesale prices and agency prices are not the same, generally about 170 in a square bar Now on the market cabinet specifications are generally 2440 * 750-760 * 15mm, large board is generally 3200 * 1600 * 15mm, these two are standard board. Generally have to 3100 * 1500 * 15, the size of foreign are generally 20mm thick.

Q:How about Tiantuo plate

How to buy plate (1) whether it is environmentally friendly. According to the provisions of the indoor building materials formaldehyde emission must be less than or equal to 1.5mg / l, if more than 5mg / l is exceeded. (2) wood moisture content. When the wood moisture content is higher than the equilibrium moisture content of the environment, the wood will dry shrink, otherwise it will absorb moisture expansion. The main cause of wood cracking and deformation is that the moisture content is too high or too low. (3) Do not just cheap. Low-priced materials are usually sold and crushed and formaldehyde seriously exceeded the material, should be to the regular market to buy, it is best to buy a brand of materials. (4) the purchase of wood flooring when the tree species do not have to worry about the name, the election is the most important dealer.

Q:Will the sheet metal processing bending coefficient and plate thickness, bending angle, bending radius is what is the relationship between the urgent!

The bending factor and the thickness of the material you said bending angle ah bend the radius and bending the bending machine up and down mold, the length of the bending parts are related We are using experience value. After all, conventional standard brick algorithm does not take into account the equipment wear and tear, sheet material thickness of the situation Different thickness determines the different bending factors such as 1mm cold rolling fold 90 degrees and 2mm cold rolling fold 90 degrees Our actual situation is 1mm coefficient is 1.8 2mm coefficient is 3.5 The same angle 90 degrees is a bending factor of 60 degrees is 1/2 of the bending coefficient of 45 degrees is 1/3 of the bending coefficient of less than 30 degrees according to the different thickness of the buckle or buckle a 0.5 Material and plate thickness as different materials, the bending coefficient is different The bending radius is related to the bending machine. The standard single V or double V is even the default value of the other V slots. But there are customers who need to be too small or a large bend radius will be specific to the analysis Too small bend radius, our approach is to plan the groove to bend, so that the bending radius is very small, almost vertical right angle bending Too large bending radius, the upper mold can be used on the corresponding arc on the mold (note that the upper arc of the R is the inside of your bending R, if the outside R according to the outer R minus a plate thickness to determine the model) Or a large R30 50 or more, you can use a split bend, which requires the calculation of the cut-in angle and the last knife angle, as well as the size and angle of each knife There is a part of the length of this I think a lot or machine equipment and related to our machine a long time 1.5mm stainless steel over 1m according to the case will not use 8mm mold bending
