Kev Siv Tseem Ceeb Ntawm Glycidyl Methacrylate

Vim tias GMA molecules muaj ob pawg ua haujlwm, active vinyl thiab ionic reactive epoxy, uas tuaj yeem ua polymerized los ntawm kev ua haujlwm thiab ionic, lawv tuaj yeem siv rau kev hloov kho ntawm ethylene thiab condensed polymers. GMA tuaj yeem cuam tshuam rau hauv polymerization nyob rau hauv peb txoj kev: ua ntej, thaum lub sij hawm ethylene polymerization, epoxy pawg nyob rau ntawm ceg saw, uas yog ib tug "O" hom polymer [2]; Qhov thib ob yog epoxy nplhaib qhib, uas tso cov vinyl pawg ntawm cov saw saw, piv txwv li "V" - zoo li cov polymer [3]; Qhov thib peb yog cov tebchaw nrog cov nquag hydrogen react nrog GMA los qhib cov nplhaib thiab tsim cov saw hlau ntawm pawg epoxy. Siv ib qho ntawm peb txoj kev saum toj no, lub sijhawm rau kev hloov pauv polymer hauv cov tshuaj tiv thaiv polymerization. Nyob rau hauv cov nqe lus ntawm coatings, lub xub ntiag ntawm GMA tuaj yeem txhim kho qhov hardness, glossiness, adhesion, thiab huab cua tsis kam ntawm cov txheej, thiab tuaj yeem siv rau hauv acrylic coatings, acrylic ester coatings, alkyd resin coatings, vinyl chloride resins, thiab qee cov dej-raws li txheej. .

Acrylic acid emulsions, binders, thiab non-woven fabrics tuaj yeem txhim kho qhov adhesion rau hlau, iav, cement, thiab polytetrafluoroethylene thaum siv GMA; Thaum siv cov ntaub tsis-woven rau kev sib txuas cov latex, txhim kho lawv cov kev tiv thaiv kev ntxhua khaub ncaws yam tsis muaj kev cuam tshuam rau kev xav. Thaum cov khoom siv hluavtaws ua tiav, qhov no tuaj yeem txhim kho kev txhaj tshuaj moldability, extrusion formability, thiab txhim khu kev adhesion ntawm resin thiab hlau. Thaum siv rau cov khoom siv hluavtaws, nws tuaj yeem txhim kho lub zog xim ntawm cov xim tsis zoo, txhim kho xim ceev, thiab txhim kho wrinkle thiab shrinkage kuj. Cov khoom no tuaj yeem txhim kho qhov rhiab heev, kev daws teeb meem, thiab corrosion kuj ntawm photosensitive resins. Cov khoom no tuaj yeem raug grafted nrog polyolefin los txhim kho tensile zog thiab flexural zog. Tsis tas li ntawd, cov khoom no kuj tseem siv tau los ua cov khoom siv raw rau ion pauv resins, sib xyaw resins, kev kho mob xaiv pom daim nyias nyias, anticoagulants, cov ntaub ntawv kho hniav, tsis soluble adsorbents, thiab lwm yam. Kuj siv rau kev hloov kho roj hmab.
