Sawirka Soo-bandhigay ee Polybutadiene-ka Kooxda Hydrogenated Hydroxyl ee Hydrogenated HTPB

Polybutadiene-ka la joojiyay ee HTPB

Sharaxaad Gaaban:

HTPB waa polymer-ka fog ee dareeraha ah, oo ah caagga dareeraha ah ee cusub. Sifooyinka 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 naqshad cusub sida HTPB iyadoo hal -OH silsiladdiiba iyo nooca Hydrogenated).

Astaamaha

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)

HTPB-ga Hydrogenated waa homopolymers-ka hydrogenated ee butadiene, labaduba waa hydroxyl group-ka oo la joojiyay waxayna ku habboon yihiin isticmaallo badan. Sababtoo ah dheregga kooxda 1,2-vinyl, polybutadienes-kani waxay leeyihiin xasillooni kiimiko oo aad u fiican oo muddo dheer ah.

Sifooyinka sida:

Qaab-dhismeed aad u dabacsan

Nabaad-guurka

Joogto dielectric hooseeya

Iska caabin kiimiko oo wanaagsan

Kooxaha hydroxyl ee falcelinta leh

Xasilloonida muddada dheer

Codsiyada

Wax ka beddelka resin-ka, resin-ka urethane (rinjiyada, dhejisyada, wakiilada dahaarka), agabka dahaarka korontada, elastomers-ka TPU

Baakaynta iyo Kaydinta

Baakad:

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

Tilmaamaha badbaadada:

Kaydintu waa inay ahaataa mid qabow, qalalan oo hawo leh. Xaaladda ugu fiican waa -20 ~ 38℃. Muddada kaydinta waa 12 bilood, haddii ay dhacdo, wali waa la isticmaalaa haddii ay heer caadi ah gaarto iyada oo dib loo tijaabinayo. Marka gaadiidku uu roobka ka fogaado, iftiinka qorraxda. Ha ku qasin oksaydheeye xooggan.
