CAS 69102-90-5 HTPB Polybutadiene yavuyeho hidroxyl HTPB yo gukoresha propellant, kole, sealants, na coating

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.)

Iyo n'umuyoboro w'amashanyarazi, umuyoboro uhuza ibintu mu bushyuhe bw'icyumba cyangwa mu bushyuhe bwinshi bishobora gutanga imiterere ya 3D y'umuyoboro w'amashanyarazi. Imiterere y'amashanyarazi ifite imiterere myiza ya mekanike, cyane cyane ubudahangarwa bwiza na hydrolysis, ubudahangarwa na aside na alkali, ubudahangarwa, ubudahangarwa bw'ubushyuhe buke kandi urinda amashanyarazi neza.

Polyurethanes zakozwe muri HTPB zishobora gukorwa hakurikijwe imiterere yihariye; polyurethanes zishobora kuba zoroshye cyane cyangwa zikomeye kandi zikomeye. Bimwe mu bicuruzwa birimo: paneli zikomeye zo gukingira ifuro; amapine n'amapine aramba (akoreshwa mu gukaraba amapine, escalators, skateboards, nibindi); ibyuma bihagarika imodoka; ibinyabutabire by'amashanyarazi; kole ikora neza; irangi ryo hejuru n'ibifunga ku buso; insinga za sintetike (urugero, Spandex); tapi yo munsi yayo; ibice bya pulasitiki ikomeye (urugero, ku bikoresho by'ikoranabuhanga).

Uburyo bw'ingenzi bwo gukoresha HTPB ni mu muyoboro wa roketi ukomeye. Uhuza ogisijeni, lisansi n'ibindi bikoresho mu buryo bukomeye ariko bushobora guhindurwa mu buryo busanzwe muri sisitemu nyinshi za ogisijeni. Polyurethane isukuye ikora nk'amavuta muri bene ubwo buryo. Urugero, umuyoboro wa "HTPB/AP/Al=12/68/20", bivuze ko, ukurikije uburemere, HTPB hamwe n'umuti uvura 12% (umuyoboro n'amavuta), ammonium perchlorate 68% (umuyoboro ugabanya ubushyuhe), na aluminiyumu 20% (amavuta).

Ibikoresho bisa nabyo, bikunze kwitwa APCP (ammonium perchlorate composite propellant) bikoreshwa muri roketi nini. APCP isanzwe itanga imbaraga zidasanzwe inshuro 2-3 z'ibikoresho byihariye by'ibikoresho byirabura bikoreshwa muri moteri ntoya nyinshi.

HTPB ikoreshwa kandi nk'amavuta ya roketi avanze.

Imiterere y'imikorere ya HTPB ni iyi ikurikira:

1. Gutinya amazi

2. Amatsinda ya hyroxyl atuma umuntu amererwa neza

3. Ubushyuhe buke bwo guhindura ikirahuri

4. Ibara rike - amazi afite ubushyuhe bwinshi kandi asobanutse neza

5. Kurwanya hydrolysis

6. Ubudahangarwa bw'ubushyuhe buri hasi

7. Ubushuhe buke butuma umuntu adashobora kubona amazi menshi

8. Ubudahangarwa ku aside n'ibice by'amazi

9. Ubudahangarwa bukomeye bwo kwangirika

10. Gufata neza cyane ibintu bitandukanye

11. Imiterere y'amashanyarazi akingira ubushyuhe
