Cov lus qhia
Thaum BG-2655-100 tawg, nws viscosity yuav nce. Thaum sib xyaw nrog hydrophilic polyol dispersions, nws tuaj yeem diluted nrog dej ua ntej lossis me me ntawm cov kuab tshuaj ntxiv los tswj cov viscosity nce, xws li propylene glycol methyl ether acetate (PMA), propylene glycol diacetate (PGDA), thiab nws. pom zoo kom siv cov kuab tshuaj polyurethane qib (dej cov ntsiab lus <0.05%) rau dilution, nrog rau cov ntsiab lus tsis tsawg tshaj li 40%. Ua cov kev sim tshwj xeeb thiab kev ntsuas kev ruaj ntseg ua ntej siv. Yog tias qhov sib tov tom qab ntxiv BG-2655-100, nws yuav tsum tau siv rau hauvlauj kaub.
khaws cia
Cov khoom yuav tsum tau muab cia rau hauv lub thawv kaw kom tsis txhob khov thiab kub. Nws raug nquahu kom khaws cov ntim ntim kom zoo ntawm qhov ntsuas kub ntawm 5-35 ℃. Lub txee lub neej ntawm cov khoom yog kaum ob lub hlis txij li hnub tsim khoom. Tom qab lub txee lub neej dhau lawm, nws raug nquahu kom ua qhov kev ntsuam xyuas ua ntej siv.
Cov khoom yog rhiab heev rau cov dej noo thiab reacts nrog dej los tsim cov pa roj carbon dioxide thiab urea, uas tuaj yeem ua rau lub thawv siab nce thiab ua rau muaj kev phom sij. Tom qab qhib lub ntim, nws raug nquahu kom siv nws sai li sai tau.
