Litaba - Mofani oa litsebi oa Chaena oa CAS 69102-90-5 HTPB/ Hydroxyl-Terminated Polybutadiene

HTPB (Hydroxyl-Terminated Polybutadiene) CAS 69102-90-5 ke polymer ya claw e hole ya metsi, rabara e ntjha ya metsi. Dibopeho tsa yona di a fapana hobane HTPB ke motswako ho ena le motsoako o hlwekileng, mme e entswe ho fihlela ditlhoko tse ikgethang tsa bareki. HTPB e tlwaelehileng ke R-45M moo pheletso ka nngwe ya ketane e kgaolwang ka sehlopha sa hydroxyl [OH].

Eona le moemeli oa katoloso ea ketane, moemeli oa ho hokahanya mochesong oa kamore kapa karabelong ea mocheso o phahameng li ka hlahisa sebopeho sa marang-rang a 3D sa litaba tsa ho folisa. Litaba tsa ho folisa li na le litšobotsi tse ntle tsa mechini, haholo-holo khanyetso e ntle khahlanong le hydrolysis, khanyetso ea asiti le alkali, khanyetso ea ho tsofala, khanyetso ea mocheso o tlase le khanyetso e ntle ea motlakase.

Re mofani oa litsebi oa HTTPB, Feme ea rona, e tlas'a Lefapha la Indasteri ea Lik'hemik'hale la Chaena ka kotloloho, ke yuniti e felletseng ea lipatlisiso e shebaneng le nts'etsopele ea lisebelisoa tse ncha tsa lik'hemik'hale le lisebelisoa tse tala tsa li-propellant tsa lik'hemik'hale. Re thehiloe ka 1965. Hona joale, re akaretsa sebaka sa lisekoere-mithara tse 170,000 le sebaka sa moaho sa lisekoere-mithara tse 90,000 ka boleng bohle ba thepa bo fetang RMB limilione tse 200 le basebetsi ba fetang 900, bao ho bona, e leng basebetsi ba lipatlisiso tsa mahlale ba 469 ho kenyeletsoa setho se le seng sa Chinese Academy of Engineering, baprofesa ba 10 baenjiniere ba baholo, baenjiniere ba baholo ba 98, baenjiniere ba 196. e na le mela e 8 ea lihlahisoa tsa lik'hemik'hale ka tekanyo e kholo, e ka ntša HTPB letsatsi le letsatsi ho feta 10000kgs.

Lefapheng la lipatlisiso le nts'etsopele ea li-propellant tsa lik'hemik'hale, re hlahisitse mefuta ea thepa e tala e kangHTTPB bakeng sa di-propellant tsa dikhemikhale tse tiileng le tse metsi ho latela ditlhoko tsa ntshetsopele ya difofane tsa naha le difofane tsa sepakapaka, mme di entse menehelo e meholo ntshetsopeleng ya indasteri ya dikhemikhale bakeng sa tshireletso ya naha. Ha re mofuputsi ya matla feela, ya nang le bokgoni bo phahameng ba ho etsa dipatlisiso.

Ea ronaHTTPB E na le diaphaneity e ntle, viscosity e tlase, ho hanyetsa botsofali, ts'ebetso e tlase ea mocheso

'me ts'ebetso ea ts'ebetso e ntle. HTTPB e ka sebelisoa ho:

- Sekhomaretsi

- Ho koahela

- Lihlahisoa tsa rabara

- Mafura a tiileng

- Sefutho se tsamaisang motlakase

- Lithaere tsa thepa ea mohaho lia etsoa

- Sefutho sa polybutadiene se fedisitsweng ke hydroxyl (HTPB+AP+Al)

- Lifofane le lirokete

- Le mefuta e mengata ea tšebeliso.

Re ka etsa lipatlisiso le ho ntshetsa pele mefuta e fapaneng HTTPB ho latela litlhaloso tse khethehileng tsa bareki ba rona.
