CAS 69102-90-5 HTPB Hydroxyl-terminated polybutadiene HTPB rau propellant, adhesives, sealants, coatings

Kev Piav Qhia Luv:

HTPByog ib yam roj hmab tshiab (resin), yog cov kua hydroxyl terminated polymer ntawm butadiene. HTPB muaj cov pab pawg hyroxyl reactive. Nws tuaj yeem ua rau muaj kev cuam tshuam nrog cov saw hlau txuas ntxiv, cov neeg sawv cev crosslinking hauv chav tsev kub lossis kub siab los tsim cov qauv network 3D ntawm cov ntsiab lus kho uas muaj cov khoom siv kho tshuab zoo heev, Cov polyurethanes npaj los ntawm HTPB tuaj yeem tsim rau cov khoom siv lub cev tshwj xeeb (elastic heev lossis tawv thiab nruj).

Cov khoom ua tau zoo & Cov yam ntxwv

HTPB yog cov kua polymer uas ua los ntawm cov kua dej, cov roj hmab tshiab. Cov yam ntxwv sib txawv vim HTPB yog ib qho sib xyaw es tsis yog cov tshuaj dawb huv, thiab nws yog tsim los ua kom tau raws li cov neeg siv khoom xav tau tshwj xeeb. Ib qho HTPB feem ntau yog R-45M nrog txhua qhov kawg ntawm cov saw hlau xaus nrog pawg hydroxyl [OH]. ( PS: peb tuaj yeem ua txhua yam versions ntawm HTPB raws li cov neeg siv khoom thov, thiab tsim tshiab HTPB nrog ib txoj saw ntawm hydroxyl -OH, Lub caij no, peb tuaj yeem ua hydrogenation ntawm HTPB)

Nws thiab tus neeg sawv cev txuas ntxiv, tus neeg sawv cev sib txuas hauv chav tsev kub lossis kub siab tuaj yeem tsim cov qauv network 3D ntawm cov ntsiab lus kho. Cov ntsiab lus kho muaj cov khoom siv kho tshuab zoo heev, tshwj xeeb tshaj yog zoo tiv taus hydrolysis, acid thiab alkali resistant, hnav tsis kam, tsis tshua muaj kub thiab rwb thaiv tsev zoo heev.

Cov polyurethanes uas tau npaj los ntawm HTPB tuaj yeem tsim los rau cov khoom tshwj xeeb; polyurethanes tej zaum yuav muaj zog heev lossis tawv thiab nruj. Qee cov khoom suav nrog: cov vaj huam sib luag rwb thaiv tsev ua npuas ncauj; cov log tsheb thiab cov log tsheb elastomeric ruaj khov (siv rau cov log tsheb roller coasters, escalators, skateboards, thiab lwm yam); cov bushings ncua kev lag luam tsheb; cov khoom siv hluav taws xob; cov nplaum ua haujlwm siab; cov txheej txheej saum npoo thiab cov sealants saum npoo; cov xov hluavtaws (piv txwv li, Spandex); cov ntaub pua plag hauv qab; cov khoom yas tawv (piv txwv li, rau cov twj paj nruag hluav taws xob).

Ib qho tseem ceeb ntawm kev siv HTPB yog nyob rau hauv cov khoom siv foob pob hluav taws khov kho. Nws khi cov neeg sawv cev oxidizing, roj thiab lwm yam khoom xyaw rau hauv cov khoom khov kho tab sis elastic hauv feem ntau cov txheej txheem sib xyaw ua ke. Cov polyurethane kho ua haujlwm ua roj hauv cov khoom sib xyaw ua ke. Piv txwv li, cov khoom siv propellant li "HTPB/AP/Al=12/68/20", uas txhais tau tias, sib piv los ntawm qhov hnyav, HTPB ntxiv rau 12% kho tau (cov khoom sib txuas thiab roj), ammonium perchlorate 68% (oxidizer), thiab hmoov txhuas 20% (roj).

Cov roj propellant zoo sib xws, feem ntau hu ua APCP (ammonium perchlorate composite propellant) yog siv rau hauv cov qauv rockets loj dua. Ib qho APCP ib txwm tsim 2-3 npaug ntawm cov roj propellant hmoov dub siv rau hauv feem ntau cov cav rocket me.

HTPB kuj tseem siv ua roj foob pob hluav taws sib xyaw.

Cov yam ntxwv ntawm HTPB ua raws li nram no:

1. Kev tsis muaj dej

2. Cov pab pawg hyroxyl uas muaj zog

3. Qhov kub hloov iav qis

4. Xim tsawg - kua nplaum siab meej

5. Kev tiv thaiv rau hydrolysis

6. Kev tiv thaiv kub tsawg

7. Kev nkag mus rau cov dej noo tsawg

8. Kev tiv thaiv rau cov kua qaub thiab cov hauv paus aqueous

9. Muaj zog hnav tsis kam

10. Kev nplaum zoo heev rau ntau yam khoom siv

11. Cov khoom siv hluav taws xob rwb thaiv tsev
