CTPB cas 586976-24-1 Carboxyl-Terminated Polybutadiene CTPB
Rubha repolybutadiene rabha rakabviswa simba reCarboxyl rinowanzo nzi CTPB muchidimbu. Nekuti kune carboxyl kumativi ese epolymeric molecule, iyi polymer inoramba iine chimiro chayo pamwe chete neboka recarboxyl, kupararira kwenetwork kwakanaka uye kusina terminal yakasununguka. Saka ine mashandiro akanaka kwazvo emakanika.
Mapoka ekupedzisira ecarboxyl anogona kuita ne epoxy resin, iyo ine simba rakanaka pa epoxy resin. Kana ichienzaniswa ne CTBN, CTPB ine viscosity yakaderera, kushanda zvakanaka pakupisa kwakaderera uye kuchinjika.
Chigadzirwa ichi hachingogone kushandiswa mu solid rocket propellant chete, asiwo chinogona kushandiswa mu elastomers, glues, sealing material, epoxy resin modification uye zvinhu zvinodzivirira magetsi.
Yakaputirwa mu50kg/dhiramu, 180kg/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.
