CAS 69102-90-5 HTPB Polybutadiene Hydroxyl nke a kwụsịrị na HTPB maka ihe na-akpalite ihe, ihe na-ejikọ, ihe mkpuchi, na ihe mkpuchi

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)

Ya na ihe nnọchite anya ndọtị agbụ ígwè, ihe nnọchite anya njikọta n'ime okpomọkụ ụlọ ma ọ bụ mmeghachi omume okpomọkụ dị elu nwere ike ịmepụta usoro netwọk 3D nke ọdịnaya ọgwụgwọ. Ọdịnaya ọgwụgwọ nwere ihe ndị dị mma n'ime igwe, karịsịa ezigbo iguzogide hydrolysis, acid na alkali na-eguzogide, iguzogide iyi, obere okpomọkụ na mkpuchi eletriki dị mma.

A pụrụ imepụta polyurethanes e ji HTPB mee maka ihe ndị a kapịrị ọnụ; polyurethanes nwere ike ịdị oke nro ma ọ bụ sie ike ma sie ike. Ụfọdụ ngwaahịa gụnyere: ogwe mkpuchi ụfụfụ siri ike; wiil na taya elastomeric siri ike (eji maka roller coasters, escalators, skateboards, wdg); ihe mkpuchi ụgbọ ala; ihe ndị e ji ite ọkụ eletrik rụọ; ihe ndị na-eme ka ọ dị mma; ihe mkpuchi elu na ihe mkpuchi elu; eriri sịntetik (dịka ọmụmaatụ, Spandex); ihe mkpuchi kapeeti; akụkụ plastik siri ike (dịka ọmụmaatụ, maka ngwa eletrọniki).

Otu ihe dị mkpa e ji HTPB mee bụ itinye ihe na-akpali roket siri ike. Ọ na-ejikọta ihe na-eme ka oxidizing, mmanụ ọkụ na ihe ndị ọzọ dị n'ime oke siri ike mana nke na-agbanwe agbanwe n'ọtụtụ sistemụ propellant mejupụtara. Polyurethane a gwọrọ agwọ na-arụ ọrụ dị ka mmanụ ọkụ na ngwakọta ndị dị otú ahụ. Dịka ọmụmaatụ, ihe na-akpali dị ka "HTPB/AP/Al=12/68/20", nke pụtara, nke a na-ekewa site na oke, HTPB gbakwunyere curative 12% (njikọ na mmanụ ọkụ), ammonium perchlorate 68% (oxidizer), na ntụ aluminom 20% (mmanụ ọkụ).

A na-eji ihe ndị yiri ya, nke a na-akpọkarị APCP (ammonium perchlorate composite propellant) eme ihe na rọketi ndị buru ibu. APCP nkịtị na-emepụta ihe ugboro abụọ ruo atọ nke ihe mkpuchi ntụ ntụ ojii nke ejiri mee ihe na ọtụtụ obere injin roket.

A na-ejikwa HTPB dị ka mmanụ ụgbọala rọketi ngwakọ.

Njirimara arụmọrụ nke HTPB dị ka ndị a:

1. Mmiri na-akpọnwụ

2. Otu hydroxyl na-emeghachi omume

3. Okpomọkụ mgbanwe iko dị ala

4. Agba dị ala - mmiri mmiri viscous doro anya nke ọma

5. Nguzogide hydrolysis

6. Ike iguzogide okpomọkụ dị ala

7. Mmiri na-erugharị nke ọma

8. Nguzogide megide asịd mmiri na ntọala

9. Ike siri ike nke na-eyi

10. Ezigbo nrapara na ọtụtụ ihe dị iche iche
