Itsinda rimwe rya hydroxyl HTPB CAS 69102-90-5 Hydroxyl-terminated polybutadiene HTPB ifite uruhererekane rumwe rwa hydroxyl -OH na verisiyo ya hydrogenated
HTPB / Hydroxyl-terminated polybutadiene CAS: 69102-90-5
Ibisobanuro by'ibicuruzwa:
Izina ry'imiti: Itsinda rimwe rya hydroxyl HTPB / Hydroxyl-terminated polybutadiene
Kode: HTTPB-OH
CAS: 69102-90-5
Ifishi y'ifishi:
Inyuguti: Uruhushya rwo kohereza ibicuruzwa mu mahanga rwemewe n'Ubushinwa / Uruhushya rwo kohereza ibicuruzwa mu mahanga rwa HTPB
Igipimo: GB (Icyiciro cya gisivili) / GJB (Icyiciro cya gisirikare / GJB 1327A-2003)
HTPB ni polymeri y’amazi ikoreshwa mu gukaraba, ikaba ari umupira mushya w’amazi. Imiterere yayo iratandukanye kuko HTPB ari uruvange aho kuba ikintu cyuzuye, kandi ikorwa kugira ngo ihuze n’ibyo abakiriya bakeneye byihariye. HTPB isanzwe ni R-45M aho buri mpera y’uruhererekane ihagarikwa n’itsinda rya hydroxyl [OH].PS: dushobora gukora verisiyo iyo ari yo yose ya HTPB uko abakiriya babisabye, no gushushanya HTPB nshya dukoresheje urunigi rumwe rwa hydroxyl -OH, Hagati aho, dushobora gukora hydrogenation ya HTPB.)
Itsinda rimwe rya hydroxyl HTPB ni umusaruro wa polybutadiene ufite amatsinda ya hydroxyl ku ruhande rumwe, ushobora kugera ku gukuba kabiri kw'amatsinda ya hydroxyl na vinyl. Ifite reactivity nyinshi, hydrophobicity nziza cyane na dielectric, kandi ikora neza mu gutunganya.
HTPB ifite diaphaneity nziza, viscosity nke, idashaje, ikora neza mu bushyuhe buke, idakoresha hydrolysis, idakoresha aside na alkali, idashira kandi ifite ubushobozi bwiza bwo gukingira amashanyarazi.
kandi imikorere yo gutunganya ni myiza. HTTPB irashobora gukoreshwa muri:
- Kolesha
- Ibifunga
- Polima
- Ibikoresho by'amashanyarazi bikingira
- Ibikoresho bikingira amazi no kwirinda ingese
- Gusiga irangi
- Ibikoresho bya polyurethane
- Ibikoresho bya Rubber
- Ibikomoka kuri lisansi ikomeye
- Umushongi utera umuyaga
- Amapine y'imodoka n'indege y'ibikoresho by'ubwubatsi
- Poroteyine ya polybutadiene ivanyweho na Hydroxyl (HTTPB+AP+Al)
- Ibindege, Roketi na Misile
- amavuta yo kwisiga
- n'ibindi byinshi byo gukoresha.
Gupakira:
Ipakiye mu 50kg/ingoma, 170kg/ingoma, Igihe cyo kubika ni umwaka 1.
Amabwiriza y'umutekano:
Ububiko bugomba kuba ahantu hakonje, humutse kandi hahumeka umwuka. Uburyo bwiza ni hagati ya -20 ~ 38℃. Igihe cyo kubika ni amezi 12, niba kirangiye, kigomba gukoreshwa niba kijyanye n'igihe cyo kongera kugerageza. Iyo gutwara bigomba kwirinda imvura, izuba n'izuba. Ntukavange n'umuti ukomeye wo kugabanya ubushyuhe.
