CAS 69102-90-5 HTPB Polybutadiene-ka la joojiyay ee Hydroxyl HTPB ee loogu talagalay kicinta, dhejisyada, shaabadaha, dahaarka

HTPB waa polymer-ka fog ee cidiyaha dareeraha ah, oo ah caagga dareeraha ah ee cusub. Sifooyinku way kala duwan yihiin sababtoo ah HTPB waa isku-darka halkii laga isticmaali lahaa isku-darka saafiga ah, waxaana loo sameeyay si loo daboolo shuruudaha gaarka ah ee macaamiisha. HTPB-ga caadiga ah waa R-45M iyadoo dhammaad kasta oo silsiladda ah lagu dhammeeyo koox hydroxyl [OH]. PS: waxaan samayn karnaa nooc kasta oo HTPB ah sida macaamiishu codsadaan, iyo naqshad cusub oo HTPB ah oo leh hal silsilad oo hydroxyl -OH ah, Dhanka kale, waxaan samayn karnaa hydrogenation-ka HTPB)

Iyada iyo wakiilka fidinta silsiladda, wakiilka iskutallaabta heerkulka qolka ama falcelinta heerkulka sare waxay abuuri kartaa qaab-dhismeedka shabakadda 3D ee macluumaadka daaweynta. Mawduuca daaweynta wuxuu leeyahay sifooyin farsamo oo aad u fiican, gaar ahaan iska caabin wanaagsan oo ku wajahan hydrolysis, aashitada iyo alkali u adkaysta, iska caabinta xirashada, iska caabinta heerkulka hooseeya iyo dahaarka korontada ee aadka u fiican.

Polyurethanes-ka laga sameeyay HTPB waxaa loo farsameyn karaa sifooyin gaar ah oo jireed; polyurethanes-ku waxay noqon karaan kuwo aad u dabacsan ama adag oo adag. Qaar ka mid ah alaabada waxaa ka mid ah: guddiyada dahaarka xumbo adag; taayirada iyo taayirada elastomeric-ga ee waara (loo isticmaalo meelaha lagu duubo, kor u kaca, skateboard-yada, iwm.); bushings-ka joojinta baabuurta; isku-dhafka dheriga korontada; dhejisyada waxqabadka sare leh; dahaarka dusha sare iyo shaabadaha dusha sare; fiilooyinka macmalka ah (tusaale ahaan, Spandex); rooga hoostiisa; qaybaha adag ee balaastikada ah (tusaale ahaan, qalabka elektarooniga ah).

Adeegsiga muhiimka ah ee HTPB waa mashiinka gantaalka adag. Waxay ku xidhaa wakiilka oksaydhka, shidaalka iyo maaddooyinka kale cuf adag laakiin dabacsan oo ku jira inta badan nidaamyada isku-dhafka ah. Polyurethane-ka la daaweeyay wuxuu u shaqeeyaa sidii shidaal isku-darkaas. Tusaale ahaan qalabka sida "HTPB/AP/Al=12/68/20", taasoo la macno ah, marka loo eego cufnaanta, HTPB oo lagu daray 12% oo daaweyn ah (xidhka iyo shidaalka), ammonium perchlorate 68% (oksaydheeye), iyo budada aluminium 20% (shidaal).

Gawaarida la midka ah, oo badanaa loo yaqaan APCP (ammonium perchlorate composite propellant) ayaa loo isticmaalaa gantaalada moodeelka waaweyn. APCP-ga caadiga ah wuxuu soo saaraa 2-3 jeer kicinta gaarka ah ee budada madow ee loo isticmaalo inta badan matoorada gantaalada yaryar.

HTPB waxaa sidoo kale loo isticmaalaa shidaal gantaal isku-dhafan.

Sifooyinka waxqabadka ee HTPB sida soo socota:

1. Nabaad-guurka biyaha

2. Kooxaha hydroxyl ee falcelinta leh

3. Heerkulka kala-guurka galaaska oo hooseeya

4. Midab hooseeya - dareere dhalaalaya oo cadcad

5. Iska caabbinta hydrolysis-ka

6. Iska caabin heerkul hooseeya

7. Qoyaan yar oo aan si fiican u gudbin

8. Iska caabbinta asiidhyada biyaha iyo saldhigyada

9. Iska caabin adag oo xirasho ah

10. Ku dhegid aad u fiican oo loogu talagalay noocyo kala duwan oo substrates ah

11. Sifooyinka dahaarka korontada
