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:Is the epoxy sheet toxic?: Strictly speaking, epoxy sheets are toxic. But the toxicity is very weak, are the actual non-toxic products. ??? Because, simple epoxy resin is environmentally friendly non-toxic, but usually it is necessary and the use of curing agent, curing agent are generally some toxicity, modified amine curing agent can only be low toxicity, completely non-toxic impossible. Other types of curing agent are some toxicity, but the extent of a different, but basically are low toxicity. Where is the organic products, how can the toxicity of no Yeah, after curing epoxy glue no toxicity, it can be said that toxicity will not be higher than other plastic products Therefore, the epoxy resin sheet in daily life, is classified as the actual non-toxic products.

Q:Cabinet door environmental protection grade how to divide: European environmental standards are divided into E2, E1, E0 three grades, which E0 level environmental protection cabinet formaldehyde emission at least, so the whole cabinet is the most direct way to identify whether the environmental protection cabinet is to see whether the brand cabinet environmental commitment, if necessary, Of the environmental rating certificate, the most important thing is to see the store's environmental testing report, which have seen more can be more at ease. E1, E0 level is the European countries based on the content of free formaldehyde in wood-based panels to divide, but also China's home use of artificial plate standards. Domestic brand cabinets are widely used to achieve the European E1 standard green sheet, has reached the cabinet environmental safety and safety requirements, and environmental standards higher E0 grade sheet, because it does not contain green moisture and adhesives, its toughness and moisture resistance relative Low, easy to tide fracture, generally used as a furniture substrate, not suitable for use in the kitchen humid environment. At the same time, because the E0 level cost higher than the E1 level two or three percent, therefore, really use E0 level plate manufacturing cabinet manufacturers rarely. Many manufacturers have claimed that their sheet is E0-class environmental standards of the plate, in fact, there will inevitably be speculation in the composition of the inside.

Q:Help, carpenters plate problem, is the green of Nanjing is good, or the horse's green sea good?: Luyuan good, Ma On Shan green sea to be careful, mostly fake more. Can really be really good, but the price of 135 is not estimated to be true

Q:Now home furnishings are what plate?: Plywood splint, also known as plywood, line known as fine core board. Made of three or more layers of one millimeter thick veneer or sheet adhesive. Is the most commonly used furniture handmade furniture. Plywood is generally divided into 3 PCT board, 5 PCT board, 9 PCT board, 12 PCT board, 15 PCT board and 18 PCT board six specifications (1 PCT is 1mm).

Q:Cabinet cabinet board types which: PVC cabinets High visibility of the plastic board cabinet is often said that the PVC cabinets, the advantages of this cabinet is more waterproof and moisture, but many people say that it can not withstand the high temperature, so easy to deformation. The king just felt that many of the dishes used in Chinese food will be habitually placed directly on the table, or next to the cabinet cabinet surface, and even a lot of Chinese cooking habits seem to have a very long and very high temperature. However, the words come back, I do not set fire in the kitchen, but maintenance, to be more dedicated to it.

Q:Now a lot of furniture on the market, do not know the solid wood or wood imitation of the wood: First of all, you can distinguish from the pattern, pure solid wood furniture pattern is no change in the law, and paste leather furniture pattern changes are very regular, such as butterfly-like, or words continue to head, and pure solid wood furniture patterns are irregular The second measure is that you can look at the furniture is not used to start the falcons, falcons are solid wood furniture, one of the necessary technology, the so-called falcon, that is, slot, wood and wood convergence is not glue and nails , But rather like a child to play the same building blocks, so that together, this is why the reasons for environmental protection of solid wood furniture, and the layout of the furniture is absolutely impossible to use frying craft third trick, generally better solid wood furniture, in addition to In addition to the structure of the falcon, there should be splicing technology, splicing is divided into two kinds, tooth and then flat, as the name suggests, tooth connection, is the two selected wood, both ends are playing like a tooth-like teeth, and then two pairs Together, this is the tooth connection, if there are teeth of the furniture, take the wardrobe door, the door inside and outside the tooth interface must be on the fourth move, solid wood furniture should generally be round circle The design of the corner, because only the wood, in order to withstand the pressure to cut into a circular, the layout is not possible

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: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

Q:What are the characteristics of wood?: Light weight, high strength than high, good elasticity, impact resistance, easy processing

Q:What are the plates for the bathroom?: Generally do not have to do the plate, are made of glass and brick
