Selelekela sa ho Sireletsa Foam ka Spray
Ho thibela ho futhumala ha foam e fafaditsweng ho fetotse indasteri ya meaho le ya kaho ka thepa ya yona e phahameng ya ho thibela ho futhumala le bokgoni ba ho kwala moya. Jwalo ka moetsi ya ka sehloohong wa di-catalyst tsa polyurethane, re utlwisisa karolo ya bohlokwa eo thepa ena e e bapalang ho hlahiseng dihlahiswa tsa ho thibela ho futhumala ha foam e fafaditsweng tse sebetsang hantle.
Foam ea polyurethane e fafalitsoeng (SPF) ke sehlahisoa sa lik'hemik'hale se entsoeng ka ho kopanya le ho sebetsana le likarolo tse peli tsa metsi - isocyanate le polyol resin. Ha likarolo tsena li kopana le li-catalyst tsa rona tse khethehileng tse kang MXC-70, li atoloha ka potlako ho etsa foam e sireletsang mocheso, e koalang moea le e fanang ka khanyetso ea mongobo.
Mokhoa oa ho Sireletsa Foam ka Spray
Saense e ka morao ho ho kwahela foam ya spray e itshetlehile tshebetsong ya polymerization:
1. Karabelo ea Lik'hemik'hale:Ha dikarolo tse pedi (lehlakore la A le lehlakore la B) di kopana, di qala karabelo ya exothermic
2. Katoloso:Motsoako o atoloha ka makhetlo a 30-60 bophahamo ba oona ba pele ka metsotsoana e seng mekae.
3. Ho phekola:Foam e thatafala ho ba sebopeho sa polasetiki se tšoarellang sa sele
