EHTPB epoxidation-HTPB Epoxidized hydroxyl-terminated polybutadien(epoxy-HTPB)
EHTTPB keHTTPB ketane ea limolek'hule e hlahisang lihlopha tsa epoxy, tse nang le melemo e kang ho hanyetsa oli, ho hanyetsa botsofali, ho pepeseha hantle, le ts'ebetso e ntle ea mocheso o tlase. Lihlopha tsa hydroxyl qetellong ea ketane ea limolek'hule le lihlopha tsa hydroxyl ka har'a ketane ea limolek'hule
Sehlopha sa epoxy ke sehlopha se arabelang se ka phekoloang ka li-isocyanate tse fapaneng le li-epoxy curing agents.
Polima e phekotsoeng e na le thepa e ntle ea 'mele le ea lik'hemik'hale, matla a ho khomarela a babatsehang ho thepa e fapaneng e seng ea tšepe e kang litšepe le khalase, thepa e ntle ea dielectric, sekhahla se tlase sa ho fokotseha, le ho thatafala.
Tekanyo e phahameng, e tsitsitseng ho isa ho alkali le boholo ba tsona, e ka ntlafatsa haholo thepa ea mechini, matla a sekhomaretsi le ho hanyetsa mocheso oa thepa ea polyurethane.
EHTTPB e ka sebelisoa bakeng sa likhomaretsi, li-sealant, liphahlo, ho tiisa resin ea epoxy, li-polyurethane elastomers, jj.
E pakiloe ka 50kg/moropa, 170kg/moropa, Nako ea polokelo ke selemo se le seng.
Litaelo tsa polokeho:
Polokelo e lokela ho ba sebakeng se pholileng, se omileng le se nang le moea o kenang. Boemo bo botle ka ho fetisisa ke pakeng tsa -20 ~ 38℃. Nako ea ho boloka ke likhoeli tse 12, haeba e fela, e ntse e sebelisoa haeba e le maemong a tloaelehileng nakong ea tlhahlobo hape. Ha lipalangoang li lokela ho qoba pula, khanya ea letsatsi. U se ke ua kopanya le oxidizer e matla.
