HTPB Hydrogenated Hydroxyl Group-Terminated Polybutadiene
Te hauwaiHTPBKo te Polybutadiene Kua Whakamutua te Roopu Hydrogenated Hydroxyl
Taipitopito hua:
Ingoa matū: HTPB Whakawai
Momo: Putanga hauwai
Tātai:
Pūāhua: Haina Kaituku Whakamana / raihana kaweake HTPB
Paerewa: GB (Civil Grade) / GJB (Military Grade/ GJB 1327A-2003)
Ko te HTPB he waerau maikuku mamao wai, te rapa wai hou. He rereke nga taonga na te mea he ranunga te HTPB ehara i te puhui parakore, ka hangaia kia tutuki nga whakaritenga motuhake a nga kaihoko. Ko te HTPB angamaheni ko R-45M me ia pito o te mekameka ka mutu ki te roopu hydroxyl [OH]. (PS: Ka taea e matou te mahi i nga momo putanga o te HTPB kia rite ki te tono a nga kaihoko, me te hoahoa hou i te HTPB me te mekameka kotahi o te hydroxyl -OH, I tenei wa, ka taea e matou te mahi hydrogenation o te HTPB)
Mo te Hydrogenated HTPB he homopolymers hauwai o te butadiene, he rua-mutunga hydroxyl roopu-whakamutua, he pai mo te whānuitanga o nga whakamahinga. Na te waiwai o te roopu 1,2-vinyl enei polybutadienes he pai te pumau matū mo te wa roa.
Āhuatanga hei:
Hanganga tino ngawari
Te hauwai
Korehiko iti te pumau
He pai te aukati matū
Rōpū hydroxyl tauhohe
Te pumau mo te wa roa
Whakarerekē Resin, kapia urethane(peita, whakapiringa, matū whakakikorua), he mea whakamau hiko, TPU elastomers
Te takai:
Kikī i roto i te 50kg/drum, 170kg/drum, Ko te wa rokiroki he 1 tau.
Nga tohutohu haumaru:
Ko te rokiroki me noho ki te hauhautanga, maroke me te hau. Ko te ahua pai kei waenga i te -20 ~ 38 ℃. 12 marama te roa o te oranga, mena ka pau, ka whakamahia tonu mena ka eke ki te paerewa ma te whakamatautau ano. I te wa e tika ana te kawe i te ua, te ra. Kaua e uru ki te oxidizer kaha.
