Q:What are the differences between FR5 sheet and FR4 sheet?

FR-5 has better advantages than FR-4: 1, TG, TD higher; 2, better heat resistance, about twice the normal FR-4; 3, Z-CTE smaller, suitable for high Laminates; 4, T288 better.

Q:What kind of sheet is durable?

Cut a small piece from the plate (10 cm X20 cm) in boiling water for 20 minutes, if not deformed quality is very good.

Q:What is the PS board? What is his performance? What is his relevant national standard or industry standard?

Polystyrene (PS) extruded sheet Features and uses: The product is polystyrene as the main raw material, made by extrusion, free coloring, odorless and tasteless non-toxic, not to bacteria growth, with rigidity, insulation, good printing, etc., mainly for packaging, container equipment, Daily decoration, general electrical and construction and other industries. PS polystyrene decorative board is polystyrene particle molding compound in the extrusion plate on the extrusion molding of organic polymer sheet. Features: PS polystyrene decorative board is a thermoplastic. The specific gravity of 1.05, the melting temperature of 150-180 ℃, the absorption rate is low, light transmission rate of up to 88-92%. Ability to organic acid, alkali, salt and lower alcohols, but also soluble in esters and ketones.

Q:Small size of the bedroom ready to do tatami, the site selection is very troubled, the existing tatami shop, mostly MDF, Daixinban, plywood, finger board, mainly with large amount of plastic, formaldehyde flavor. Some people say that with the Russian red fir, is to buy wood made of sheet and then paint it? Please understand the teacher on the environmental protection, compression capacity to recommend a suitable platform for the plate,

Hello, do not know where you are tatami, I have done 8 years and the room, I help you solve this problem bars. As we all know: plywood, Daixinban, MDF, etc. are high plastic content of the plate, but here also shows that the formal professional and room manufacturers will not use these plates! In the country, especially in the northern region, with camphor pine in particular, affordable, color texture and feel, by the majority of customers accepted. But here to explain is that even the board is still stitching Pinus sylvestris, the market even if there is a pure use of a full-page, you have to understand, but the choice of large manufacturers of the plate, the general formaldehyde content is controlled Within the scope of the national requirements. Sheet is a sheet, in addition to the column, beams, slide part of the open with a wooden side, and other are generally integrated materials. Speaking of environmental protection, large manufacturers of the plate will generally not use any problems, and then is the paint, paint the quality of the product determines the quality and service life, and the room is generally done varnish processing, is divided into topcoat, primer, And so on multiple processes. Paint paint to be smooth, visual no impurities, feel no bulging particles, film hardness is high. Also give you a recommended plate, that is, Ash. Well, to say so much, the key is to choose the formal professional manufacturers, the current domestic and the room market quite a mixed bag, due to low access threshold, many couples mixed into them, the price war damage is ultimately the interests of consumers. You can go to the formal large-scale building materials store, choose a qualified regular manufacturers! I hope I can help you!

Q:How to degrease the wood

Vacuum drying method The vacuum drying method is a method in which wood is piled up in a closed container and dried at a lower pressure than atmospheric pressure to remove part of the resin, and vacuum drying is suitable for wood having good air permeability. Vacuum drying method, can not achieve the desired effect. Vacuum drying is mainly characterized by drying faster than other methods, compared with other drying methods, drying time can be shortened about 25 ~ 1 2. Japan's Naito Truth [4] Drying of Douglas fir wood by high-frequency vacuum drying is considered to be effective for degreasing and mainly in the early stages of drying, since the moisture removal in the wood is in the early stages of drying, so its degreasing action is also in the early stages of drying. ] And other larch wood for cooking, vacuum and artificial drying, that cooking, vacuum degreasing effect is good, because the cooking to increase the permeability of wood.If the cooking, vacuum drying after artificial drying degreasing effect is better, because the vacuum drying Shorten the drying time.But the vacuum drying equipment is complex, the investment is high, there are vacuum drying machine manufacturers can use this method.To generally improve the degreasing effect, often using two or more degreasing method combination, such as Liquid immersion plus steam drying, pharmacy impregnation vacuum, steam vacuum pressure vacuum and other methods. The manufacturer can be based on the actual situation of the factory, choose the appropriate method for their own.

Q:Solid wood furniture and panel furniture which pollution is small?

Popular, solid wood furniture is certainly a small pollution, but the market is full of a lot of parallel imports of solid wood furniture, such as solid wood paste, obviously the middle of the particleboard, posted a bark on the outside that is solid wood furniture, furniture and sheet furniture in my It seems there is no difference, choose a good solid wood furniture from the material, technology point of view. General people think that solid wood furniture is certainly all solid wood, but simply not, so when you buy furniture to ask the material, all parts of the material to ask, there is a desktop is solid wood, table legs are not, some desktop is good Wood, table legs with parallel wood, but the price tag is good wood price. Anyway, if you are very stressed that pollution is small, you will see manufacturers have no 10 ring certification, which is the most authoritative environmental certification, of course, people have money to buy another matter on the matter. You'd better buy a brand name, so safe, because to tell the truth, many small workshops which produce furniture, and then to the supermarkets to pay a long lease, transformed into a good furniture, and is completely deceptive. There is to shop around!
