Abstract: Tšebeliso ea malapenghydroxypropypropinyl methylcellSebakeng sa ho kenya motho tlhahisong ea li-pvc tse nang le degree e phahameng ea polymeriation. Litholoana tsa mefuta e 'meli ea hydroxypropyl methylceluse ka har'a thepa ea PVC e nang le degree e phahameng ea polymeriation e ile ea hlahlojoa. Liphetho li bontšitse hore ho ka etsahala hore e nke sebaka sa hydro sexypropyproppyl methyl cellulose ea hae ea ho tsoa.
Boemo ba PVC bohōkotse-ea-polymerization " [1]. Ha ho bapisoa le li-pvc tse tloaelehileng tsa PVC, tse phahameng tsa PVC li na le khatello e phahameng, khatello e nyane ea mocheso, ho hanyetsa ha mocheso le ho senya. Ke sebaka se setle sa rabara se ka sebelisoang 'me se ka sebelisoa mehala ea likoloi tsa koloi, lithapo le likhopolo, batsamaisi ba bongaka, jj. [2].
Mokhoa oa tlhahiso oa PVC ka tekanyo e phahameng ea polymerization ke boholo ba ho emisoa ha polymeriation [3-4]. Ha u etsa mokhoa oa ho emisoa, ho nyahama ke moemeli oa bohlokoa oa ho thusa, 'me boholo ba eona bo tla ama sebopeho, le ho monya letsoho la boholo ba polasetiki. Ka tloaelo ts'ebetso e sa qus'o hasanyetsoeng ke lefu la joala le hydroxypropypropyL methylcelulo le polyvinyl joala ba ho qhaqha ha li-pelyvinyl.
