Hydrophobic dej iav perlite khoom

Cov txheej txheem ntau lawm ntawm hydrophobic dej iav perlite rwb thaiv tsev cov khoom lag luam yog kom sib xyaw ua ke nrog 10} Cov pa dej sib xyaw ua ke nrog 10 ~ tom qab ntawd. Nyob rau tib lub sijhawm, ntxiv dej rau cov organic silicon daws nrog cov ntsiab lus zoo ntawm 30% los ua 0.8% daus. Lub khob dej hydrophobic perlite thermal rwb thaiv tsev cov khoom tuaj yeem nqa tawm tom qab tau muab raus rau hauv kev daws rau ob peb feeb. Cov txheej txheem yog siv los tsim cov citic hydrophobic nthuav dav perlite. Txog 10kg ntawm cov organic silicon kev daws yuav tsum rau txhua lub cubic cub, thiab cov khoom yog thaum kawg ziab. Kev tsim cov khoom siv dej no yog kom sib xyaw rau cov dej hydrophobic ncaj qha rau hauv cov iav dej ncaj qha rau hauv lub khob tas li thiab qhuav ntawm 400 degree rau cov khoom tiav. Cov txheej txheem txuj ci ntawm hydrophobic dej iav perlite rwb thaiv tsev cov khoom yog: kev ceev ceev<300kg/m3; compressive strength 1.0Mpa; thermal conductivity at room temperature 0.056~0.07W/(m·K); after immersion in water for 30min and 8 days, the water absorption rate of hydrophobic water glass perlite insulation products is 2% and 31.4% respectively, while the water absorption rate of ordinary water glass products under the same conditions is 157% and 187% respectively.
