Boka rehydroxyl rimwe chete HTPB CAS 69102-90-5 Hydroxyl-terminated polybutadiene HTPB ine cheni imwe chete yehydroxyl -OH uye hydrogenated version

Tsananguro pfupi:

HTTPB ipolymer yemvura iri kure neclaw, rabha itsva yemvura. Hunhu hwayo hunosiyana nekuti HTPB musanganiswa kwete chinhu chakachena, uye inogadzirwa kuti ienderane nezvinodiwa nevatengi. HTPB yakajairika iR-45M ine magumo ese echeni inogumiswa neboka rehydroxyl [OH]. (PS: tinogona kugadzira dhizaini nyowani seHTPB ine -OH imwe chete pacheni).

Panguva iyi, tinogona kuita hydrogenation yeHTPB.

Zvinhu zvirimo

HTPB ipolymer yemvura iri kure neclaw, rabha itsva yemvura. Hunhu hwayo hunosiyana nekuti HTPB musanganiswa kwete chinhu chakachena, uye inogadzirwa kuti ienderane nezvinodiwa nevatengi. HTPB yakajairika iR-45M ine magumo ese echeni anogumiswa neboka rehydroxyl [OH].PS: tinogona kuita chero shanduro dzeHTPB sekukumbira kwevatengi, uye kugadzira HTPB itsva necheni imwe chete yehydroxyl -OH, Panguva iyi, tinogona kuita hydrogenation yeHTPB)

HTPB imwe chete yehydroxyl chigadzirwa chepolybutadiene chine mapoka ehydroxyl kune rimwe divi, izvo zvinogona kuita kuti hydroxyl ne vinyl groups zvigadzikane kaviri. Ine reactivity yakakwira, hydrophobicity yakanaka uye dielectric properties, uye inoshanda zvakanaka pakugadzirisa.

Mashandisirwo

HTPB ine diaphaneity yakanaka, viscosity yakaderera, inodzivirira kukwegura, inoshanda zvishoma pakupisa, inodzivirira hydrolysis, inodzivirira acid nealkali, inodzivirira kusakara uye ine hunhu hwakanaka hwekudzivirira magetsi.

uye mashandiro ekugadzirisa akanaka. HTTPB inogona kushandiswa mu:

- Namira

- Zvisimbiso

- MaPolymers

- Zvinhu zvemagetsi zvinodzivirira kupisa

- Zvinhu zvinodzivirira ngura uye zvinodzivirira mvura

- nezvimwewo zvakasiyana-siyana zvekushandisa.

Kurongedza & Kuchengeta

Kurongedza:

Yakaputirwa mu50kg/dhiramu, 170kg/dhiramu, Nguva yekuchengetera igore rimwe chete.

Mirayiridzo yekuchengetedza:

Kuchengetera kunofanira kunge kuri panzvimbo inotonhorera, yakaoma uye inofefetedza mweya. Mamiriro akanaka ari pakati pe -20 ~ 38℃. Nguva yekuzorora ndeyemwedzi gumi nemiviri, kana yapera, ichiri kushandiswa kana yasvika padanho repamusoro kuburikidza nekuyedzazve. Kana kutakurwa kunofanirwa kudzivirira mvura, chiedza chezuva. Usasanganisa neoxidizer yakasimba.
