Kushushu ukuthengisa i-polyether polyurethane acrylate enevumba elimnandi eyenziwe ngamaplanga, iphepha kunye neeplastiki zokugquma

ZCI-6203 luhlobo lwe-polyether ye-polyurethane acrylate.I-polyether polyol ifinyeziwe njenge-polyether.I-oligomer ene-ether bond (- ror -) kwikhonkco eliphambili kunye namaqela angaphezu kwamabini e-hydroxyl (- OH) kwiqela lokugqibela okanye iqela lecala.Ilungiselelwe i-polymerization ye-initiator (i-compound equkethe iqela elisebenzayo le-hydrogen) kunye ne-ethylene oxide (EO), i-propylene oxide (PO), i-epoxy butane (Bo) phambi kwe-catalyst.Imveliso enkulu ye-polyether yi-glycerol (glycerol) njenge-initiator kunye ne-epoxide.Iintlobo ngeentlobo ze-polyether polyols ngokubanzi ziveliswa ngokutshintsha indlela yokutya (edibeneyo okanye eyahlukileyo), umlinganiselo wedosi kunye nomyalelo wokutyisa we-Po kunye ne-EO.

Isalathiso sayo sobugcisa: i-viscosity yi-40000-70000pa S / 25℃, ixabiso le-asidi <0.5 (NCO%), ukusebenza kwe-3 (ixabiso lethiyori), ulwelo olungenambala okanye oluphuzi olubonakalayo;Le mveliso ineenzuzo zokuqina okuhle, amandla aphezulu efilimu, umsebenzi wokuphendula okuphezulu, ibhloko eqinisiweyo kunye nokunye.Isetyenziswa ngokubanzi kwi-inki yokunyanga, ifenitshala yomthi, ukutyabeka phantsi, ukugquma kwephepha, ukugquma ngeplastiki, ukutshiza nge-vacuum, ukutyabeka ngesinyithi kunye nezinye iindawo.

Ikhonkco eliphambili le-zc6203 liqulethe i-ether bond (- ror -), kwaye iqela lokugqibela okanye iqela lecala liqukethe i-oligomers kunye namaqela angaphezu kwe-2 ye-hydroxyl (- OH).Yenziwe nge-polymerization yokuvula i-ring ye-polymerization ephantsi ye-molecular weight polyols, i-polyamines okanye i-compounds equkethe i-hydrogen esebenzayo kunye ne-olefins ene-oxidized phantsi kwesenzo se-catalysts.I-olefins ene-oxidized ikakhulu yi-propylene oxide (propylene oxide) kunye ne-ethylene oxide (i-ethylene oxide), apho i-propylene oxide ibaluleke kakhulu.Ubunzima be-molecular of polyether kunye ne-hydroxyl-propylene glycol kunye ne-tetrahydroxy-propylene glycol esetyenziswayo eqhelekileyo yi-4000-400.I-polyether resins ezisetyenziselwa ukunamathiswa kufuneka zisuse i-alkaline catalysts eseleyo ngexesha le-polymerization, kuba inokwenza i-dimerization ye-isocyanates kwaye ichaphazele umgangatho wokunamathela.
