Kupisa kutengesa kunhuhwirira polyether polyurethane acrylate yehuni, bepa uye epurasitiki coatings

ZC6203 ndeye polyether mhando polyurethane acrylate.Polyether polyol yakapfupikiswa se polyether.Iyo oligomer ine ether bond (- ror -) mucheni huru uye anopfuura maviri mapoka ehydroxyl (- OH) muboka rekupedzisira kana boka redivi.Iyo inogadzirirwa ne polymerization yeinitiator (compound ine inoshanda hydrogen boka) ine ethylene oxide (EO), propylene oxide (PO), epoxy butane (Bo) pamberi pekatalyst.Iyo yakakura kubuda yepolyether ndeye glycerol (glycerol) sekutanga uye epoxide.Yakasiyana-siyana yakawanda polyether polyols inogadzirwa nekushandura nzira yekudyisa (yakavhenganiswa kana kupatsanurwa), chiyero chedosi uye kurongeka kwePo neEO.

Yayo tekinoroji index: viscosity ndeye 40000-70000pa S / 25℃, acid value <0.5 (NCO%), kushanda 3 (theoretical value), isina ruvara kana yellowish inoonekera mvura inoonekera;Ichi chigadzirwa chine zvakanakira kusimba kwakanaka, simba remufirimu rakakwirira, chiitiko chakanyanya chekuita, yakasimbiswa block uye zvichingodaro.Inoshandiswa zvakanyanya mukuchenesa inki yekurapa, fenicha yehuni, pasi pasi, kupfekedza mapepa, kupfekedza kwepurasitiki, kupfapfaidza vacuum, kupfekedza simbi nemimwe minda.

Iketani huru yezc6203 ine ether bond (- ror -), uye boka rekupedzisira kana boka rerutivi rine oligomers ane anopfuura 2 hydroxyl mapoka (- OH).Iyo inogadzirwa nekuvhura mhete yepolymerization yeakaderera mamorekuru huremu polyols, polyamines kana makomisheni ane inoshanda haidrojeni ine oxidized olefins pasi pekuita kwezvinokonzeresa.Oxidized olefins inonyanya kukosha propylene oxide (propylene oxide) uye ethylene oxide (ethylene oxide), iyo propylene oxide ndiyo inonyanya kukosha.Huremu hwehuremu hwepolyether ine hydroxyl-propylene glycol uye tetrahydroxy-propylene glycol inowanzoshandiswa ndeye 4000-400.Polyether resins inoshandiswa seanonamira inofanira kubvisa zvakasara alkaline catalysts panguva yepolymerization, nekuti inogona kukonzeresa dimerization yeisocyanates uye kukanganisa kunaka kweanonamatira.
