Polybutadiene nke a kwụsịrị na Hydrogenated HTPB
Ejiri hydrogen mee ihe HTPB Polybutadiene nke a kwụsịrị na Hydroxyl Group
Nkọwa ngwaahịa:
Aha Kemịkalụ: HTPB ejiri hydrogenated mee
Ụdị: Ụdị hydrogenated
Usoro:
Àgwà: Onye na-ebupụ ihe ikike na China / ikike mbupụ HTPB
Ọkọlọtọ: GB (Ọkwa Obodo) / GJB (Ọkwa Agha/ GJB 1327A-2003)
HTPB bụ polima mkpụcha aka mmiri mmiri, rọba mmiri mmiri ọhụrụ. Njirimara ya dị iche iche n'ihi na HTPB bụ ngwakọta kama ịbụ ihe dị ọcha, a na-emepụtakwa ya ka o zuo oke ihe ndị ahịa chọrọ. HTPB nkịtị bụ R-45M nke na-akwụsị njedebe ọ bụla nke yinye ahụ site na otu hydroxyl [OH].PS: anyị nwere ike ime ụdị HTPB ọ bụla dịka ndị ahịa si chọọ, ma mepụta HTPB ọhụrụ site na iji otu yinye hydroxyl -OH, Ka ọ dị ugbu a, anyị nwere ike ime hydrogenation nke HTPB)
Maka HTPB, ha bụ homopolymers nke butadiene nke nwere hydrogenated, ha bụ hydroxyl group nke a na-akwụsị ma dabara adaba maka ọtụtụ ojiji. N'ihi njupụta nke otu 1,2-vinyl, polybutadienes ndị a nwere ezigbo nkwụsi ike kemịkalụ ogologo oge.
Njirimara dị ka:
Ọdịdị dị oke mgbanwe
Mmiri na-akpọnwụ
Dielectric dị ala na-agbanwe agbanwe
Nguzogide kemịkal dị mma
Otu hydroxyl na-emeghachi omume
Ịkwụsi ike ogologo oge
Ihe ndị na-agbanwe resin, resin urethane (agba, ihe na-eme ka ihe dị n'ime ya dị ọcha, ihe mkpuchi), ihe ndị na-egbochi ọkụ eletrik, ihe ndị na-eme ka ihe dị n'ime TPU dị ọcha
Nkwakọ ngwaahịa:
A na-etinye ya n'ime 50kg/drum, 170kg/drum, Oge nchekwa bụ otu afọ.
Ntuziaka nchekwa:
Nchekwa kwesịrị ịdị n'ebe dị jụụ, kpọrọ nkụ, ma nwee ikuku ikuku. Ọnọdụ kacha mma bụ n'etiti -20 ~ 38℃. Ndụ nchekwa nke ọnwa 12, ọ bụrụ na ọ gwụchaa, a ka na-eji ya ma ọ bụrụ na ọ ruru ọkọlọtọ site na nnwale ọzọ. Mgbe njem kwesịrị izere mmiri ozuzo, a ga-ezere anyanwụ.
