I-Thermoplastic Acrylic Resins yiklasi yeereyini ze-thermoplastic ezenziwe nge-polymerizing acrylic acid, i-methacrylic acid kunye nezinto eziphuma kuzo ezifana ne-esters, i-nitriles, kunye ne-amides.Inokuthanjiswa ngokuphindaphindiweyo bubushushu ize yomelezwe ngokupholisa.Ngokuqhelekileyo, yikhompawundi ye-polymer ehambelanayo, enokuthi ibe yi-homopolymer okanye i-copolymer, ineempawu ezilungileyo zomzimba kunye nezomatshini, igqwesileyo ekuxhathiseni imozulu, ukuxhathisa imichiza, kunye nokumelana namanzi, kwaye inokukhanya okuphezulu kunye nokugcinwa kombala.I-resin ye-thermal ye-acrylic esetyenziswa kwi-coating industry ngokubanzi ine-molecular weight of 75 000 ukuya kwi-120 000. Isetyenziswa ngokuqhelekileyo ngokudibanisa ne-nitrocellulose, i-cellulose acetate butyrate kunye ne-perchlorethylene resin ukuphucula iimpawu zefilimu.
I-resin thermoplastic acrylic resin luhlobo lwe-solvent-based acrylic resin, enokuthi inyibilike kwaye inyibilike kwi-solvent efanelekileyo.I-coating elungiselelwe yi-solvent i-evaporated yi-solvent kwaye i-macromolecule idityaniswe kwifilimu, kwaye akukho mpendulo ye-crosslinking eyenzekayo ngexesha lokubunjwa kwefilimu, oluhlobo olungasebenziyo.ukutyabeka.Ukuze kuphunyezwe iipropati ezingcono zomzimba kunye neekhemikhali, ubunzima be-molecular ye-resin kufuneka benziwe bukhulu, kodwa ukuze kuqinisekiswe ukuba umxholo oqinileyo awuphantsi kakhulu, ubunzima be-molecular abunakuba bukhulu kakhulu, ngokubanzi kumashumi amawaka. amaxesha, iipropati zomzimba kunye neekhemikhali kunye nokusebenza kolwakhiwo lulungelelene.
