How to find out the portfolio of blowing real estate agents for XPS production

In my own previous how to we talked about how exactly to configure your XPS production line. Today, I am going to let you know something about how to determine the portfolio from the blowing real estate agents for XPS production. I will discuss from 4 factors, local regulation, supply availability, local insulation regular, and technical problems.



Of all first, local regulation, probably the most well-known blowing agent of XPS is Freon, a series of halocarbon including CFCs, HFCs and hcfcs. Every nation offers its own rules about the use of Freon. In most created countries, HCFC is banned now, while in some developing countries like China, still can use it until 2030, Indonesia can use it until 2040. But many countries are undertaking the new intend to increase the phasing out plan of HCFCs. One thing I must address is the fact that because of the poor solubility in polystyrene, CO2 cannot be used as blowing agent only; it has to be used in combination with other co-blowing agent collectively like ethanol, dME or butane etc. as solvent to help CO2 solve into the polystyrene.

Secondly, source availability. In some national countries, some forms of blowing providers aren't available. For instance, in some Middle East countries, ethanol isn't available and not permitted to import, and that means you have to make use of something else to be alternatives. And in a few national countries, actually HFCs aren't available and not permitted to use, let alone HCFCs. You must consult with your power to start to see the source availability.

Finally, local insulation standard. Nearly every national country has its standard of thermal conductivity of XPS panel. Let's take China; the China nationwide standard of thermal conductivity of XPS can be 0.030. Alternatively, some nationwide countries don't use thermal conductivity because the regular; they use thermal resistance R or value value instead. But so how exactly does the typical has something to do with your recipe of blowing agent? The nice reason is the fact that using different blowing agent can result in different thermal conductivity. For example, by using HFCs or HCFCs, it is possible to control the lambda worth below 0.029. However if you use CO2 plus ethanol, it really is hard to help make the lambda worth under than 0.033. To get the lambda worth below 0.030, some ongoing companies are employing the mixture of HFC, CO2 and ethanol.

The final issue, I'd like to talk about may be the relationship between thickness, hardness and the recipe of blowing agent. Using HCFCs or HFCs extrusion system is simpler to obtain thickness like 15cm. If you use CO2 alone as the primary blowing agent, it would be very hard to get such width unless your line can produce 1.5 ton each hour. But CO2 is certainly advisable once you produce high compressive strength board like 1000kpa for special use, because CO2 has smaller cell quantity which is helpful to obtain finer cell structure of the board.
