CAS 69102-90-5 HTPB whakakorikori totoka Hydroxyl-mutu polybutadiene HTPB mo te awhi, te whakapiri, te hiri
HTPB / Hydroxyl-mutu polybutadiene CAS: 69102-90-5
Taipitopito hua:
Ingoa matū: Hydroxyl-terminated polybutadiene
Waehere: HTPB, HTPB-R45M
CAS: 69102-90-5
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 taatau te mahi hoahoa hou hei HTPB me te kotahi -OH mo ia mekameka)
Ka taea e ia me te kaihoko toronga mekameka, te kaihoko whakawhiti i roto i te pāmahana rūma me te tauhohenga teitei o te pāmahana ka taea te whakaputa i te hanganga whatunga 3D o te rongoa ihirangi. Ko te ihirangi rongoa he pai rawa nga taonga miihini, ina koa he pai te aukati ki te waiwai, te waikawa me te kawakore, te aukati kakahu, te iti o te pāmahana me te tino pai te whakamaarama hiko.
Ko nga polyurethanes kua oti te hanga mai i te HTPB ka taea te hanga mo nga ahuatanga tinana motuhake;Ko nga polyurethanes he tino rapa, he uaua ranei, he maro.Ko etahi o nga hua ko: nga panui whakamatao pahuka;nga wira elastomeric me nga potae (e whakamahia ana mo nga roera roera, escalators, skateboards, etc.);nga rakau whakatārewatanga waka;pūhui kohua hiko;nga piripiri mahi teitei;paninga mata me te hiri o te mata;muka waihanga (hei tauira, Spandex);whariki raro;nga waahanga kirihou-maamaa (hei tauira, mo nga taputapu hiko).
Ko tetahi tono nui o te HTPB kei roto i te toka toka toka.Ka herea e ia te kai whakahaora, te wahie me etahi atu kai ki roto i te papatipu totoka engari rapa i roto i te nuinga o nga punaha whakahiato.Ko te polyurethane kua rongoa hei wahie i roto i enei ranunga.Hei tauira ko te mea whakaraerae hei "HTPB/AP/Al=12/68/20", ko te tikanga, he rite ki te papatipu, HTPB me te rongoa 12% (te here me te wahie), te ammonium perchlorate 68% (oxidizer), me te paura konumohe 20% (hinu).
He rite tonu nga kaikawe, e kiia ana ko APCP (ammonium perchlorate composite propellant) ka whakamahia i roto i nga roera tauira nui ake.Ko te APCP angamaheni ka whakaputa 2-3 nga wa i te hihikotanga motuhake o te paura pango e whakamahia ana i roto i te nuinga o nga motuka takirirangi iti.
Ka whakamahia ano te HTPB hei wahie toka ranu.
He pai te diaphaneity o te HTPB, he iti te viscosity, he pakari te pakeke, he iti te mahi o te pāmahana, he parenga Hydrolysis, he waikawa me te kawakore, he whakakakahu me te pai o nga taonga whakamatao hiko.
a he pai te mahi tukatuka.Ka taea te whakamahi HTPB i:
- Whakapiri
- Kaiiriiri
- Polymers
- Nga taonga whakamaarama hiko
- Nga rauemi parewai me te waikura
- Whakakikorua
- Nga rauemi polyurethane
- Hua rapa
- Te wahie totoka
- Whakahau
- Nga potae motika me nga waka rererangi o nga rawa hanganga
- Hurihiko-whakamutu polybutadiene propellant(HTPB+AP+Al)
- Aerospace, Rocket and Missile
- me era atu momo whakamahinga maha.
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.
