Kub muag khoom uas muaj ntxhiab polyether polyurethane acrylate rau ntoo, ntawv thiab yas coatings

ZC6203 yog ib hom polyether polyurethane acrylate.Polyether polyol yog abbreviated li polyether.Nws yog oligomer nrog ether daim ntawv cog lus (- ror -) nyob rau hauv cov saw tseem ceeb thiab ntau tshaj ob pawg hydroxyl (- OH) nyob rau hauv pab pawg kawg lossis pab pawg sab.Nws yog npaj los ntawm polymerization ntawm cov neeg pib (cov tshuaj muaj cov active hydrogen pawg) nrog ethylene oxide (EO), propylene oxide (PO), epoxy butane (Bo) nyob rau hauv lub xub ntiag ntawm catalyst.Cov zis ntau tshaj plaws ntawm polyether yog glycerol (glycerol) ua tus pib thiab epoxide.Ntau yam polyether polyols feem ntau yog tsim los ntawm kev hloov pauv kev pub mis (sib xyaw lossis cais), ntau npaum li cas thiab kev noj zaub mov ntawm Po thiab EO.

Nws qhov Performance index: viscosity yog 40000-70000pa S / 25℃, acid value <0.5 (NCO%), functionality 3 (theoretical value), colorless los yellowish transparent kua nyob rau hauv tsos;Cov khoom no muaj qhov zoo ntawm qhov zoo toughness, siab zaj duab xis lub zog, siab tshuaj tiv thaiv kev ua si, solidified block thiab hais txog.Nws yog dav siv nyob rau hauv lub teeb curing number case, ntoo rooj tog, pem teb txheej, ntawv txheej, yas txheej, nqus spraying, hlau txheej thiab lwm yam teb.

Cov saw tseem ceeb ntawm zc6203 muaj ether daim ntawv cog lus (- ror -), thiab cov pab pawg kawg lossis sab pawg muaj oligomers nrog ntau dua 2 pawg hydroxyl (- OH).Nws yog tsim los ntawm lub nplhaib qhib polymerization ntawm qis molecular hnyav polyols, polyamines los yog cov tebchaw uas muaj cov nquag hydrogen nrog oxidized olefins nyob rau hauv qhov kev txiav txim ntawm catalysts.Oxidized olefins feem ntau yog propylene oxide (propylene oxide) thiab ethylene oxide (ethylene oxide), uas propylene oxide yog qhov tseem ceeb tshaj plaws.Qhov hnyav molecular ntawm polyether nrog hydroxyl-propylene glycol thiab tetrahydroxy-propylene glycol hauv kev siv ntau yog 4000-400.Polyether resins siv los ua cov nplaum yuav tsum tshem tawm cov residual alkaline catalysts thaum lub sij hawm polymerization, vim hais tias lawv muaj peev xwm catalyze lub dimerization ntawm isocyanates thiab cuam tshuam qhov zoo ntawm adhesives.
