Astaamaha

HTPB waa dareere polymer cidiyaha fog fog, caag dareere cusub.Guryuhu way kala duwan yihiin sababtoo ah HTPB waa isku dhafka halkii ay ka ahaan lahayd xarun saafi ah, waxaana loo soo saaray si loo buuxiyo shuruudaha gaarka ah ee macaamiisha.HTPB-ga caadiga ah waa R-45M iyadoo cidhif kasta oo silsiladda ah lagu joojiyo koox hydroxyl [OH].

Waxaa iyo wakiilka kordhinta silsilad, wakiilka crosslinking ee heerkulka qolka ama falcelinta heerkulka sare dhalin kara qaab-dhismeedka network 3D ee content.The daawaynaya waxa uu leeyahay guryaha farsamo aad u fiican, gaar ahaan iska caabin wanaagsan hydrolysis, acid iyo alkali adkaysi, xidho iska caabin ah, iska caabin heerkulka hoose iyo dahaarka koronto oo aad u fiican.

Polyurethane laga diyaariyey HTPB waxaa lagu farsamayn karaa siyaalo gaar ah oo jireed;polyurethane waxaa laga yaabaa inay noqdaan kuwo aad u jilicsan ama adag oo adag.Alaabooyinka qaarkood waxaa ka mid ah: dahaarka xumbo adag oo adag;taayirada elastomeric ee waara (loo isticmaalo roller coasters, escalators, skateboards, iwm.);kaynta joojinta baabuurta;xeryahooda dheriga korontada;xabagta waxqabadka sare;dahaarka dusha sare iyo daboolayaasha dusha sare;fiilooyinka synthetic (tusaale, Spandex);rooga hoostiisa;qaybo caag adag ah (tusaale, qalabka elegtarooniga ah).

Codsiga muhiimka ah ee HTPB wuxuu ku jiraa gantaalaha adag.Waxay ku xidhaa wakiilka oksaydhaynta, shidaalka iyo maaddooyinka kale ee adag laakiin cufka ah ee inta badan hababka kicinta ka kooban.Polyurethane-ka la daweeyay wuxuu u shaqeeyaa sidii shidaal isku-darka noocaas ah.Tusaale ahaan soo-saareyaasha sida "HTPB/AP/Al=12/68/20", taas oo macnaheedu yahay, oo loo qaybiyey cuf, HTPB oo lagu daray daawaynta 12% (binder iyo shidaalka), ammonium perchlorate 68% (oxidizer), iyo aluminium budada 20% (shidaal).

Dabeecadaha la midka ah, oo inta badan loo yaqaan APCP (ammonium perchlorate composite propellant) ayaa loo adeegsadaa gantaalada nooca waaweyn.APCP caadiga ah waxay soo saartaa 2-3 jeer dareenka gaarka ah ee budada madow ee loo isticmaalo inta badan matoorada yar yar.

HTPB waxa kale oo loo isticmaalaa sidii shidaal isku-dhafan.

Codsiyada

HTPB waxay leedahay diapaneity wanaagsan, viscosity hooseeya, caabbinta gabowga, waxqabadka heerkulka hooseeya, caabbinta Hydrolysis, caabbinta acid iyo alkali, xidhashada caabbinta iyo sifooyin koronto oo aad u fiican

iyo waxqabadka processing waa wanaagsan yahay.HTPB waxaa loo isticmaali karaa:

- Xabag

- Selents

- Polymers

- Qalabka dahaarka korontada

- Qalabka ilaalinta biyuhu iyo daxalka

- Dahaarka

- Qalabka polyurethane

- Alaabta caagga ah

- Shidaal adag

- Dhaqaale

- Baabuurka iyo diyaaraduhu taayirada qalabka dhismaha

-HTPB+AP+Al)

- Hawada sare, gantaalada iyo gantaalaha

- iyo sidoo kale noocyo badan oo isticmaalka ah.

HTPB 应用

Baakaynta & Kaydinta

Baakad:

Waxaa lagu soo xidhay 50kg/durbaan, 170kg/durbaan, Muddada kaydinta waa 1 sano.

Tilmaamaha badbaadada:

Kaydinta waa inay ahaataa mid qabow, engegan oo hawo leh.Heerkulka ugu fiican waa -20-38 ° C.Nolosha shelf ee 12 bilood, haddii ay dhacdo, weli la isticmaalo haddii ilaa heerka caadiga ah dib loo tijaabiyo.Marka gaadiidku waa inuu ka fogaado roobka, iftiinka qorraxda.Ha ku darin oksidizer xooggan.
