What is the allowable error of polystyrene board bulk density?

The bulk density of the insulation board of the EPS system is 18-20 kg.

Polystyrene board is different according to the different parts used, for example, the bulk density of 20 kg when used on the exterior wall is generally 1 cubic meter, and the bulk density of 25 kg is sometimes required when used on the roof.

The full name of polystyrene board is polystyrene foam board, also known as foam board or EPS board.

It is a white solid with a fine closed-cell structure that is made of expandable polystyrene beads containing a volatile liquid blowing agent and heated in a mold after being heated and pre-formed. The form is like buying shock-absorbing foam inside furniture.

Now the state does not have this standard.

The bulk density of the insulation board of the EPS system is 18-20 kg.

Summary. The water absorption rate of expanded polystyrene board (EPS board) is higher than that of extruded polystyrene board (XPS board), which is easy to absorb water, which is a disadvantage of this material. The influence of the water absorption rate of the insulation board on its thermal conductivity is obvious, with the increase of water absorption, its thermal conductivity also increases, and the thermal insulation effect also deteriorates, so this point should be paid special attention to.

Hello, I am the official cooperative tutor of Q&A, I am honored that Zheng Zhi can answer your questions for you, I have seen your questions, please shout for a while, I will analyze your questions in detail and give you real-time answers.

Like well, the bulk density of poly base hall benzene board specification error, EPS system insulation board bulk density in 18-20 thousand grams, polystyrene board according to the different parts of the use of different parts, for example, used on the exterior wall is generally required to be 1 cubic meter when the bulk density of 20 kilograms, used on the roof sometimes requires 1 cubic meter when the bulk density of 25 kilograms.

Hello, the bulk density of EPS system insulation board is 18-20 kg, and the polystyrene board is different according to the different parts of the hand, for example, it is generally required to talk about the bulk density of 20 kg when it is buried on the outer wall, and the bulk density of 25 kg is sometimes required when it is 1 cubic meter of the building.

Reference: Polystyrene board is used as an insulation layer, the full name is polystyrene foam board, also known as foam board or EPS board. It is a white solid with a micro-closed vibrato-chain pore structure that is heated and formed by the expandable polystyrene beads containing a volatile liquid foaming agent and then heated and formed in the mold cave mausoleum.

Introduction to the form of polystyrene board, such as our liquid or buy furniture inside the shockproof foam characteristics: 1. Excellent thermal insulation performance; 2. High havoc Changwu strength and compressive performance fast shirt; 3. Superior water resistance and moisture-proof performance 4. Anti-corrosion and durable performance.

Main uses: 1> used for building walls, roof insulation, composite code Changlu temperature board delay with fast transfer of insulation layer; 2> Thermal insulation materials for vehicles, ship refrigeration equipment and cold storage; 3> It is used for decoration and engraving various models. 4> used as a protective layer for the waterproof layer. Water absorption of expanded polystyrene board.

The water absorption rate of expanded polystyrene board (EPS board) is higher than that of extruded polystyrene board (XPS board), which is easy to absorb water, which is a disadvantage of this material. The influence of the water absorption rate of its thermal insulation board on its thermal conductivity is obvious, with the increase of the water absorption of several birds, its thermal conductivity also increases, and the thermal insulation effect of potatoes and fruits also deteriorates, so this point should be paid special attention to.

I hope the above orange will help you If you are satisfied with me, please give a thumbs up If you feel that what is given to you is not detailed enough or you have other questions, the bureau is always welcome to continue to consult Tong Oak in real time, thank you

How much can 18 kg be up and down. is a composite specification.

More than 4mm differential information, to provide reference, the time to answer the question is always short, the teacher has finished answering for you. Hope to get your likes! Do you have any more questions?

Summary. Good evening, dear. Welcome to our consulting platform 50 extruded polystyrene board refers to its density is 50 kg cubic meters of extruded polystyrene foam board, the standard weight is affected by the specific size and thickness and varies, there is no unified retail price standard, usually can be calculated according to different specifications of the product.

Regarding the allowable weight error, it mainly depends on the production process and the level of technology. Generally speaking, the weight allowable error of 50 extruded polystyrene board manufactured in accordance with the relevant standards should be within plus or minus 2%. It is also necessary to pay attention to it, because the processing, storage and transportation of extruded polystyrene board and other links may have a certain impact on its weight, so in the actual use process, its weight and allowable error may also have some fluctuations, but this fluctuation should be controlled within an acceptable range.

50. What is the allowable error of the weight of the extruded polystyrene board, and what is the standard weight.

Good evening, dear. Welcome to our consulting platform 50 extruded polystyrene board refers to Zheng with its density of 50 kilograms of cubic meters of extruded polystyrene foam board, the standard weight is subject to the specific size and thickness of the change, there is no unified retail price standard, usually can be calculated according to different specifications of the product. Regarding the allowable weight error, it mainly depends on the production process and the level of technology.

Generally speaking, the weight allowable error of 50 extruded polystyrene board manufactured in accordance with the relevant standards should be within plus or minus 2%. It is also necessary to pay attention to it, because the processing, storage and transportation of extruded polystyrene board and other links may have a certain impact on its weight, so in the actual use process, its weight and allowable error may also have some fluctuations, but this fluctuation should be controlled within an acceptable range.

Is the standard of polyben board an industry standard or a national standard.

The word "poly board" is a common name in the construction industry, which refers to extruded polystyrene foam board (XPS), which is an excellent material used in the fields of thermal insulation, sound insulation and waterproofing. Regarding the standard of polybenz board, the main domestic application is the national standard "polymer foam tuber insulation material" (GB T 23932-2009) and the industry standard "extruded polystyrene foam board" (JC T1078-2008). Among them, the first is the mandatory standard issued by the Standardization Administration of the People's Republic of China, which mainly stipulates the basic requirements and technical indicators of polymer foam insulation materials in the production, inspection and use.

The second is the industry standard formulated by the Ministry of Construction, which mainly covers the name and definition, requirements, test methods, inspection rules, signs, packaging, transportation and storage of extruded polystyrene foam board. Therefore, there are national standards and industry standards for the standard of polyben board. When choosing products, you should refer to the provisions of relevant standards, and weigh them in combination with actual needs and product quality before making a choice.
