Rigid Blend Polyols for Discontinuous sandwich panels

Rigid Blend Polyol for Discontinuous  sandwich panel    DBC-402B

Product Introduction

DBC402B 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:The stove is dedicated to the plastic used for plastic paper
Color steel, also known as: color pressure tile, is the use of color coated steel plate, the cold bending into a variety of wave-type pressure plate, it applies to industrial and civil construction, warehouses, special buildings, large span steel housing Roof, wall and interior and exterior decoration, with light, high strength, rich color, convenient construction, earthquake, fire, rain, long life, maintenance-free features, has been widely used Caigang sandwich panels Is the current building materials in a common product, not only can be a good flame retardant and environmentally friendly and efficient. Caigang sandwich board has two layers of metal panels and the middle of the polymer core insulation from the suppression. With the installation is simple, light and efficient light and efficient features. And the filling system used to close the molecular structure of the closed, you can put an end to the condensation of water vapor. The tile is used for the panel for the wall
Q:800 * 800 tiles can not stick to the sandwich panel on the wall to do
Some areas have implemented energy-saving 50% standard, and some areas have already begun to implement 65% of the standard. Insulation material thickness is determined by the design institute according to the specific building shape factor, window wall ratio, wall thickness and other factors.

Q:What is the export tax rebate rate? The The
5 cm, 10 cm, 15 cm and 25 cm The general material 5 cm price between 45 to 75 yuan; 75 cm price of 55 to 90 yuan range; 10 cm price of 70 to 100 yuan, Caigang Caigang purification plate thickness can also Custom So we must first understand their choice of materials and thickness, different scenes of the plate is not the same choice
Q:Reinforced concrete and metal sandwich board how much difference
Tower crane driver, scaffolding type of work, all kinds of welding workers
Q:Color steel sandwich board roof, glass wall how the house insulation
(Including: Fluorocarbon metal paint, fluorocarbon solid paint, real stone paint, imitation stone paint, granite, relief supporting, imitation brick texture, texture matching, etc) and insulation materials series (including: XPS , EPS, PUR, phenolic board, rock wool board, ultra-thin insulation board), for the old and new concrete, steel structure, real brick wall, hollow brick wall, brick wall wall, combined with the company to install patent, Construction of the wall installation TDD insulation decorative board is not only suitable for the new building exterior insulation and decoration, but also for the old building of low-carbon energy-saving decorative transformation, and not affected by regional differences
Q:50mm thickness of color steel foam sandwich board how much money a flat
To strengthen safety education, training and safety technology. Article 4 Special operations personnel shall, after obtaining the Special Operations Operation Certificate, carry out the corresponding work; the construction unit shall not arrange for the operating personnel who have not obtained the "special operation operation certificate" to engage in special types of work. Article 5 Special operations personnel shall strictly implement the special operating procedures and the relevant safety rules and regulations, according to the chapter operation, refused to illegal command. Article 6 special operations personnel should carry their own documents, consciously accept the employer, the safety management department of the supervision and inspection. Article VII of the special operations personnel operations, the accident hidden or insecurity factors, should be to the site safety management and the relevant person in charge of the report.
Q:Sandwich panels and Malacca ecological board what is the difference
Man can pipe the plastic tube can be directly within the tube to detect the actual deformation value
Q:The general company to re-change the new version, the replacement is very troublesome. Our company's exterior wall decoration board convenient installation, thermal insulation, waterproof moisture, noise reduction noise are interested can consult.
. different fire rating: Yanmian sandwich panels for the A-level, EPS for the B3-class, polyurethane B1 level. . different insulation properties: the three polyurethane sandwich panels the best. . waterproof performance is different: the three polyurethane and EPS better than rock wool. . the density of different: rock wool bulk density is generally 120KG / cubic meter, EPS is generally . polyurethane is generally 40. In short, the overall performance of polyurethane sandwich panels for the best, is the best choice for steel structure, Have a number.
Q:What is the quota of the demolition of the color steel plate?
Answer: safety production laws and regulations, including safety in production (BE) A
