Fa'atauga vevela polyether polyurethane acrylate mo fafie, pepa ma palasitika palasitika

ZC6203 o se polyether ituaiga polyurethane acrylate.Polyether polyol ua faapuupuuina o le polyether.O se oligomer e iai le ether bond (- ror -) i le filifili autu ma sili atu ma le lua vaega hydroxyl (- OH) i le vaega pito poʻo le vaega itu.E saunia e ala i le polymerization o le initiator (fa'apotopotoga o lo'o i ai le vaega o le hydrogen malosi) ma le ethylene oxide (EO), propylene oxide (PO), epoxy butane (Bo) i le i ai o le catalyst.Ole tele ole gaosiga ole polyether ole glycerol (glycerol) e fai ma amataga ma epoxide.Ole tele polyether polyols lautele e gaosia e ala i le suia o le faiga fafaga (fefiloi pe tu'ueseese), fua fa'atatau ma le fafaga o le Po ma le EO.

O lona fa'amatalaga fa'apitoa: viscosity o le 40000-70000pa S / 25℃, aoga aoga <0.5 (NCO%), fa'atinoga 3 (taua fa'atatau), le lanu po'o le samasama manino vai i foliga;O lenei oloa o loʻo i ai le lelei o le malosi lelei, maualuga le malosi o ata tifaga, maualuga gaioiga gaioiga, poloka faʻamalosi ma isi.E faʻaaogaina lautele i vaitusi faʻamaʻi mama, meafale fafie, faʻapipiʻi fola, faʻapipiʻi pepa, faʻapipiʻi palasitika, faʻafefeteina, faʻapipiʻi uʻamea ma isi fanua.

O le filifili autu o le zc6203 o loʻo i ai le ether bond (- ror -), ma le vaega pito poʻo le vaega pito o loʻo i ai oligomers e sili atu nai lo le 2 hydroxyl group (- OH).E faia e ala i le mama tatala polymerization o polyols maualalo mole mamafa mamafa, polyamines po o tuufaatasiga o loo i ai le hydrogen malosi ma olefins oxidized i lalo o le gaoioiga o catalysts.Ole oxidized olefins ole propylene oxide (propylene oxide) ma le ethylene oxide (ethylene oxide), lea e sili ona taua le propylene oxide.O le mamafa mole o le polyether ma le hydroxyl-propylene glycol ma le tetrahydroxy-propylene glycol i le faʻaaogaina masani e 4000-400.Polyether resins faʻaaogaina e fai ma faʻapipiʻi e tatau ona aveese faʻamaʻi alkaline totoe i le taimi o le polymerization, aua e mafai ona latou faʻamalosia le dimerization o isocyanates ma afaina ai le lelei o mea faʻapipiʻi.
