EHTPB epoxidation-HTPB Epoxidized hydroxyl-terminated polybutadien(epoxy-HTPB)
EHTTPB ndiyoHTTPB cheni yemamorekuru inoisa mapoka epoxy, ayo ane zvakanakira zvakaita sekudzivirira mafuta, kudzivirira kukwegura, kujeka kwakanaka, uye kushanda zvakanaka pakupisa kwakaderera. Mapoka ehydroxyl ari pamagumo echeni yemamorekuru uye mapoka ehydroxyl ari mucheni yemamorekuru
Boka re epoxy iboka rinoita basa rinogona kurapwa ne isocyanates dzakasiyana-siyana uye epoxy curing agents.
Iyo polymer yakagadziriswa ine hunhu hwakanaka hwemuviri uye hwemakemikari, simba rakanaka rekunamatira kune zvakasiyana-siyana zvisiri zvesimbi zvakaita sesimbi negirazi, hunhu hwakanaka hwe dielectric, mwero wakaderera wekupwanya, uye kuomarara
Dhigirii repamusoro, rakagadzikana kusvika kune alkali uye akawanda mavhoriyamu, rinogona kuvandudza zvakanyanya hunhu hwemakanika, simba rekunamira, uye kuramba kupisa kwezvinhu zvepolyurethane.
EHTTPB inogona kushandiswa pakunamira, sealants, coatings, epoxy resin toughening, polyurethane elastomers, nezvimwewo.
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.
