Tsananguro pfupi:

Zita reKemikari: Epoxidized Polybutadiene (EPB)

Kodhi: EPB

Cherechedza: Tinogona kutsvagurudza nekugadzira chero shanduro itsva yeEPB zvichienderana nezvinodiwa nevatengi vedu.

Tsananguro yeChigadzirwa

EPB iboka re epoxy rinounzwa muPB molecular chain, rine zvakanakira zvekudzivirira mafuta, kudzivirira kukwegura, kujeka kwakanaka, kushanda zvakanaka pakupisa kwakaderera, nezvimwewo. Boka re epoxy riri mu molecular chain iboka rinoita reactive, rinogona kurapwa nemarudzi akasiyana-siyana e isocyanates uye epoxy curing agents.

Iyo polymer yakagadziriswa ine hunhu hwakanaka hwemuviri uye hwemakemikari, simba rakanaka rekubatanidza simbi negirazi nezvimwe zvinhu zvisiri zvesimbi, hunhu hwakanaka hwe dielectric, mwero wakaderera wekudonha, kuomarara kwakanyanya, kugadzikana kune alkali uye huwandu hwakawanda, izvo zvinogona kuvandudza zvakanyanya hunhu hwemakanika, simba rekubatanidza uye kuramba kupisa kwezvinhu zve polyurethane.

Mapoka epolar anovandudza hunhu hwekubatana kwechigadzirwa nezvinhu zvesimbi nezvisiri zvesimbi; Inogona kushandiswa mumaglues, sealants, coatings, epoxy resin toughening, polyurethane elastomers, nezvimwewo.

Kurongedza & Kuchengeta

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.
