Nkhaniyi ifotokoza za kugwiritsa ntchito methyl acrylate, kulandiridwa kuti muphunzire limodzi!
Chifukwa pali magulu awiri ogwira ntchito mu molekyulu ya GMA, gulu logwira ntchito la vinilu ndi gulu la ionic reaction epoxy, amatha kupangidwa polima munjira yogwira ntchito komanso mwa njira ya ionic, kotero angagwiritsidwe ntchito kusinthidwa kwa ethylene- mtundu ma polima ndi polycondensation ma polima, GMA akhoza kulowererapo polymerization m'njira zitatu, mmodzi ndi ethylene polymerization kuti gulu epoxy lili pa nthambi unyolo, ndiko kuti, "O GMA akhoza kulowerera polymerization m'njira zitatu: choyamba, pamene ethylene ndi polymerized kuti gulu la epoxy likhale pa unyolo wa nthambi, mwachitsanzo "O" mtundu wa polima [2]; kachiwiri, pamene epoxy imatsegula mphete kuti gulu la vinilu likhale pa unyolo wa nthambi, mwachitsanzo "V" mtundu wa polima [3] ];chachitatu, pamene pawiri yokhala ndi haidrojeni yogwira imagwira ntchito ndi GMA ndikutsegula mphete pa gulu la epoxy kuti apange unyolo.Pogwiritsa ntchito njira zitatu zomwe tazitchulazi, polima amasinthidwa muzochita za polymerization munthawi yake. kupezeka kwa GMA, kuuma, gloss, adhesion ndi nyengo kukana ❖ kuyanika filimu akhoza bwino, ndipo angagwiritsidwe ntchito zokutira akiliriki, zokutira acrylate, zokutira alkyd, vinilu kloridi utomoni, ndi zokutira madzi madzi.
Pamene GMA ntchito akiliriki emulsions, binders, ndi nsalu nonwoven, izo bwino adhesion ku zitsulo, galasi, simenti, ndi polyfluoroethylene;ikagwiritsidwa ntchito pansalu zosawomba za latexes opangidwa, imawongolera kuchapa kwawo popanda kukhudza manja awo.Mukachizidwa ndi zinthu zopangidwa ndi utomoni, izi zimathandizira kusinthika kwa jekeseni, kusungunuka kwa ma extrusion, komanso kumathandizira kwambiri kumamatira ku utomoni ndi zitsulo.Ikagwiritsidwa ntchito ngati ulusi wopangira, izi zimatha kusintha mphamvu zopaka utoto za ulusi wosapakidwa bwino, ndikuwongolera kufulumira kwa mtundu wa Zhuo, ndikuwongolera luso lodana ndi makwinya ndi anti-shrink.Izi zitha kukulitsa chidwi, kusamvana komanso kukana kwa dzimbiri kwa utomoni wa photosensitive.Izi zitha kupititsa patsogolo mphamvu zamakomedwe komanso mphamvu zosinthika polumikiza ndi polyolefin.Komanso, mankhwalawa angagwiritsidwe ntchito ngati zopangira ion kuwombola utomoni, utomoni wosakanizidwa, mankhwala kusankha kusefera nembanemba, odana coagulant, mano zakuthupi, sanali sungunuka adsorbent, etc. Amagwiritsidwanso ntchito pa mphira kusinthidwa.
