Gukoresha HTPB mu byuma bifunga no mu byuma bivanze
HTTPB ni iki n'imiterere yayo yihariye
Ushobora kwibaza icyatuma HTPB igaragara cyane mu bijyanye no kurinda inzu. HTPB, cyangwa polybutadiene yavuyeho hidroxyl, ni umugozi wihariye w'amazi. Imiterere yawo y'ibinyabutabire ifite amatsinda ya hydroxyl ku mpera z'iminyururu yayo. Aya matsinda afasha HTPB gukora umuyoboro ukomeye w'ibice bitatu iyo uyivanze n'ibindi bintu. Uyu muyoboro uha HTPB imbaraga n'ubushobozi bwayo bwo koroha.
HTPB iguma yoroshye nubwo haba mu gihe cy'ubukonje kuko ifite ubushyuhe buke bw'ikirahure cya -75°C. Ntugomba guhangayikishwa n'uko ibifunga byawe bizacika intege mu gihe cy'itumba. HTPB kandi irwanya imiti myinshi, amavuta, aside, n'ibice by'inyuma. Ubona ibikoresho biramba kandi bikarinda urugo rwawe imimerere mibi.
Inama: Uburyo bwo gukoresha HTPB mu gusuka no gushushanya ibintu mu nkono byoroshye, ndetse no mu bihe bigoye.
Impamvu HTPB ari ingenzi ku byuma bifunga n'ibivanze mu byuma bitogosha
Iyo urebye uburyo HTPB ikoreshwa mu byuma bifunga n'ibivanze, ubona inyungu nyinshi ku rugo rwawe. Ibifunga bya HTPB n'ibivanze byo mu gikoni birinda umwuka, ubushuhe n'imiti. Birinda inzu yawe amazi cyangwa kwangirika. Ubona kandi ibikoresho byinshi by'ubwubatsi bifatanye neza, bivuze ko ibikoresho byawe bifunga biguma mu mwanya wabyo.
Dore incamake y'uburyo ushobora gukoresha HTPB mu rugo rwawe:
| Ubwoko bwa porogaramu | Ibisobanuro |
|---|---|
