Thuso ea ho sebetsa ea PVC ke polymer ea thermoplastic graft e fumanoeng ho polymerization ea methyl methacrylate le acrylate ka lotion ea peo. E sebelisoa haholo-holo bakeng sa ho sebetsa le ho hlahisa thepa ea PVC. E na le phello e ntle ho ntlafatsa ts'ebetso ea ho hanyetsa thepa ea PVC. E ka lokisa mokhoa oa polymerization oa mehato e mengata e sebelisang polymerization ea lotion ea peo, ho kenyeletsoa polymerization ea setso ea lotion le core shell lotion polymerization. Monyetla oa eona o ho bokhoni ba ho laola sebopeho, boholo, botenya ba khetla, karo-karolelano ea khetla ho ea bohareng ba radius, litšobotsi tse sebetsang ka holim'a metsi, joalo-joalo tsa likaroloana ho latela litlhoko tse fapaneng nakong ea ts'ebetso ea synthesis, 'me kabo ea boholo ba likaroloana e batla e tšoana. .

Lisebelisoa tsa mantlha tsa lisebelisoa tsa ho sebetsa tsa PVC ke acrylic esters le methyl methacrylate. Tlhahisong ea 'nete, acrylate hangata e etsoa polymerized le li-monomers tse ling (joalo ka styrene, acrylonitrile, joalo-joalo) ka lotion ho etsa polima e nang le mocheso o tlase oa khalase, ke hore, mokokotlo o nang le lisebelisoa tsa elastomer, ebe e hlomathiseletsoa ka methyl methacrylate. , styrene, joalo-joalo ho etsa polima e nang le sebopeho sa likhetla tsa mantlha. Lintho tse tiileng tsa lotion ena ea polymerized lotion hangata e ka ba 45% ± 3%, 'me lotion e omisitsoe le ho felloa ke metsi ho etsa hore metsi a sehlahisoa a be ka tlase ho 1% (karolo ea boima) ho fumana lihlahisoa tsa phofo e tšoeu.

Core shell lotion polymerization ke motheo oa theknoloji ea tlhahiso ea resin ea ACR. Sebopeho sa khetla sa mantlha sa ACR se ka aroloa ka mefuta e meraro: sebopeho sa khetla se thata sa mantlha, sebopeho sa khetla se thata sa mantlha, le sebopeho sa mekato e meraro se thata. Leha ho le joalo, mofuta o ka sehloohong o rekisoang hona joale 'marakeng ke "mohaho o bonolo oa likhetla tse thata". Li-resin tsa ACR tse nang le sebopeho sena li na le ts'ebetso e ntle 'me li sebelisoa haholo. The core shell lotion polymerization ea "soft core hard shell structure" ke ts'ebetso eo ho eona monoma e thata e hlomathiseletsoang holim'a peō ea likaroloana tse bonolo tsa latex tse entsoeng ke mohato oa pele oa lotion polymerization. Mofuta le litekanyetso tsa li-emulsifiers, core-shell ratio, shell monomer feeding mokhoa, crosslinking degree ea peo ea latex particles (rubber core), boholo ba peō, le mofuta le tekanyo ea crosslinking agent kaofela li na le phello e kholo mohahong oa khetla. ea likaroloana tsa latex tsa ACR le ts'ebetso ea ho qetela ea sehlahisoa sa ACR.
