Product Description

Polyurethane Foam Systems for Intermittent Boards/Sandwich DHK-204

1.Introduction

DHK204 blend polyols is a compound which consists of polyether polyols, surfactants, catalysts, foaming agent and flame retardant in a special ratio. The foam has good thermal insulation property, light in weight, high compression strength and flame retardance and other advantages. It is widely used to produce sandwich plates, corrugated plates etc, which applies to make cold stores, cabinets, portable shelters

and so on.

Q: What is the nanometer board?: The nano-board is a material in the size of 0.1-100nm (1nm = 0.000000001 meters), and nano-plate is a ceiling industry in a plate, refers to the surface of the substrate in the use of nano-materials for processing, Scratch, corrosion resistance. Nano-buckle plate in all the metal ceilings are belong to the high-grade buckle plate type, which has the following four advantages: 1. Super anti-fouling: nano-panel surface smooth and meticulous, dust, oil is not easy to adsorb, and easy to clean, so the nano-panel has good anti-pollution characteristics. 2. Super wear-resistant: nano-panel wear resistance than the general paint more than 10 times, not easy to leave scratches. 3. Super anti-static: dust pollution and the size of the material particles, but also with the electrostatic interaction. General substances in the role of electromagnetic fields, will produce static phenomena. Electrostatic precipitates caused by dust. Nano panels eliminate the electrostatic phenomenon, easy to attract dust particles. 4. Ultra-lasting effect: many manufacturers are doing anti-fouling efforts, some in the paint blending some fine particles, some of the surface spray some of the gas. These methods are short-term effective, but no long-term effects, see the light in a few months after the failure; and nano-panel through high temperature roller, short-wave baking, its characteristics can be maintained for more than 15 years. Has excellent acid, alkali and high weather resistance, fine texture and glossy glossy, almost no color color, color selection rich and varied, bright and durable products with easy. Surface waterproof anti-oil, clean and convenient, is the top kitchen ceiling the best choice.

Q: Aluminum sheet tensile test, the sample direction is horizontal or vertical sampling? What is the relationship between the longitudinal specimen, the transverse specimen and the rolling direction of the sheet?: Sampling is generally longitudinal (rolling direction) taken by horizontal agreement by both parties

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 sheet is more environmentally friendly?: Norby forest plate are more environmentally friendly E1 level is the formaldehyde emission is 1:00, E0 level is 0:00, of course, E0 level more environmentally friendly

Q: What is the material of the Margaret Wardrobe?: There are solid wood, solid wood composite, the proposed use of solid wood composite, the brand is also good.

Q: My family's kitchen seven-shaped, the amount is a total of four meters, one meter over the top cabinet, put a hood in the middle. Under normal circumstances if the woodworking need a few fire board? Do you need a few sheets?: Cabinet fire board needs an area of 9.4 square meters (including) inside the partition, the specific area of how much (depending on how much), a sheet of 1.22 * 2.44 = 2.97 square meters, estimated the need for fire board (with loss) Four, even the top cabinet came out (these are counted on the table). Door area of about 4 square meters, count down 1.36, the door needs to buy two, but also some of the rich plate. Above for reference, if any access please do not see strange.

Q: MD board has no E1 level: There are E1 level! The There are E0 level! The Our company is producing! The CARB can be done! The

Q: Q235 material, 2.5mm thickness of the plate, flanging R corner of the smallest can not be less than how much? Is a material thickness? This problem is applied to similar flanging situation? Do sheet metal peers please help: The minimum radius of the bend is 0.3t in the direction perpendicular to the rolling pattern, 0.8t parallel to the rolling pattern, and the minimum radius is 0.5t when it is at an angle of 45 ° to the rolling direction.

Q: Sound insulation, then, with which plate is good?: Noise barriers / special insulation board: double-sided UV solid board, three boards, X board series ???Three layers: thickness 10-20mm, the maximum width of 2100mm, length 6000mm. (Can be customized) There are ten colors available (red, black, lake blue, blue, transparent, opal, advertising white, grass green, green, brown) X-type hollow board: thickness 8-20mm, the maximum width of 2100mm, length 6000mm. (Can be customized) Sound insulation: good sound insulation, can effectively reduce the noise, in the international are the preferred material for highway noise barriers. High strength: polycarbonate sunshine board strength, high security, "not broken glass" and "ring steel" reputation, is the bulletproof glass of high quality materials. Good weather resistance: the use of international advanced production technology, the board evenly distributed high concentrations of UV co-extruded layer, can effectively absorb ultraviolet light, thereby extending the life of the plate. Product Usage: 1. Office buildings, department stores, hotels, villas, schools, hospitals, sports venues, entertainment centers and public facilities of the lighting ceiling. 2. Noise barriers for highways, railways and urban viaducts. 3. Modern plant greenhouse and indoor pool of the sky. 4. Metro entrances, stations, parking lots, shopping malls, pavilions, restrooms, corridors of the canopy. 5. Bank anti-theft counters, jewelry store anti-theft window, police riot shield. 6. The airport, the factory safety lighting materials. 7. Advertising light box panel, advertising display card. 8. Household, office indoor interval, pedestrian access, guardrail, balcony, shower room sliding door.

Stability is very good. Affordable choice. Description: The color of dark reddish brown wood, texture dense and strong, with curved curved black wood texture, the island people often used to make piling boat keel and semi-circular bracket. Wood adhering to the fine characteristics of pineapple grid, is a can be used for geothermal and has a variety of color selection of subtropical wood species. Is the ideal alternative to pineapple grid, also known as small pineapple grid. On behalf of the brand: Kyrgyzstan (mid-range), Huaming (old brand of good service), Li Feng (first-line brand) Merlin wood features: heavy, more hard wear, anti-termite moisture. Stability is very good, are cost-effective species, once popular. Indonesia to reduce the cutting prices have an upward trend. Brief introduction: 1, Indian eggplant is growing in the paradise rain forest in the precious tropical hardwood, it takes 80 years to mature, in each hectare virgin forest can only find 1-5 trees.
