Kwinkalo yokusetyenzwa kweplastiki, ukuveliswa kweefilimu zekhalenda ezicacileyo bekusoloko kuyinkalo ephambili yenkxalabo kumashishini amaninzi. Ukwenza iifilimu ezikumgangatho ophezulu ezibonisa ngokucacileyo kwikhalenda, izizinzi zePVC ngokuqinisekileyo zizinto eziphambili eziyimfuneko. Izinzinzi ze-PVC zolwelo ziyathandwa ngenxa yeenzuzo zazo ezizodwa. Xa kuthelekiswa nezizinzisi zemveli eziqinileyo, zinokusasazeka okungcono. Kwinkqubo yokuvelisa iifilimu ze-calendered ezicacileyo, zinokuthi zifakwe ngokulinganayo kwizinto ze-PVC, ziqinisekisa ukuba ikhonkco ngalinye le-molecular lizinziswe ngokufanelekileyo kwaye likhuselwe, into ebalulekileyo ekugcineni ukucaca kweefilimu. Ngaphezu koko, ifom yabo yolwelo yenza inkqubo yokongeza ibe lula kwaye ichaneke ngakumbi, inqanda iziphene zokusebenza kwendawo ezibangelwa kukusasazwa okungalinganiyo kwezinzisi kunye nokubeka isiseko sokuveliswa kweefilimu zekhalenda ezicacileyo ezikumgangatho ophezulu. Ukuthetha jikelele,ulwelo PVC zizinzisiilungele iifilim zekhalenda ezicacileyo ikakhulu zibandakanyaI-Methyl Tin,I-calcium-Zinckunye neCarium-Zinc stabilizers.
I-Liquid Methyl Tin stabilizers inozinzo oluhle kakhulu lwe-thermal kwaye inokuthintela ngokufanelekileyo ukubola kwe-PVC phantsi kweemeko zokulungisa ubushushu obuphezulu, iqinisekisa ukungafihli kunye nokuzinza kombala weemveliso. Nangona kunjalo, iindleko zabo ziphezulu kakhulu. Kwezinye iimeko zezicelo apho iindleko zibuthathaka, amashishini aya kufuna ezinye izisombululo.
I-PVC Barium Zinc stabilizers luhlobo oluthile lwe-thermal stabilizers kunye nokusebenza okugqwesileyo. Kwiifilimu ze-calendered ezicacileyo, zinokubonelela ngeempawu ezintle zombala wokuqala, okwenza iifilimu zigcine ukubonakala kakuhle kunye nombala kwinqanaba lokuqala lokucubungula. Bakwanayo nokusebenza kakuhle kwexesha elide lokuzinza kwe-thermal kwaye banokuqinisekisa ukuba iifilimu azikwazi ukuguga kunye nokuguga ngexesha lokusetyenziswa okulandelayo. Okwangoku, i-lubricity ye-barium-zinc stabilizers imodareyitha, enceda ukuhamba kwezinto ngexesha lokucubungula kwaye yenza inkqubo ye-calendering ibe lula kwaye iphucule ukusebenza kakuhle kwemveliso.
I-PVC Calcium Zinc stabilizers, njengabameli be-stabilizers enobume bendalo, ngokuthe ngcembe baba yinto ephambili kwishishini. Inzuzo yabo enkulu ixhomekeke ekukhuselekeni kokusingqongileyo kunye nokungabi yingozi, ehambelana nentsingiselo yeemfuno ezingqongqo zokhuseleko lokusingqongileyo kwiimveliso zeplastiki. Kwimveliso yeefilimu ezicacileyo ze-calendered, i-calcium-zinc stabilizers inokunika iifilimu ngokubonakala kakuhle kunye nokuchasana kwemozulu. Nangona iifilimu zibonakaliswe kwiindawo zangaphandle ixesha elide, ziyakwazi ukuxhathisa ngokufanelekileyo ukuguga kunye neengxaki ze-embrittlement ezibangelwa yizinto ezifana nemitha ye-ultraviolet kunye ne-oksijini, ngaloo ndlela ukwandisa ubomi benkonzo yeefilimu.
Kufanelekile ukukhankanya okoTopJoy Chemicaligxile kwimveliso kunye nophando kunye nophuhliso lwezinzisi zolwelo. I-TopJoy Chemical ineqela lobuchwephesha kunye nobuchwepheshe obuphambili, iphonononga nzulu kushishino lwePVC kwaye izimisele ukubonelela abathengi ngemveliso yolwelo oluphezulu lwezinziso ezihlangabezana neemfuno ezahlukeneyo. Ingaba abathengi abalandela ukusebenza kweendleko bakhetha i-PVC barium-zinc stabilizers okanye abathengi abagxile ekukhuselweni kwendalo bakhetha i-PVC calcium-zinc stabilizers, i-TopJoy Chemical inokwanelisa ngokuchanekileyo iimfuno zabo kwaye incede amashishini avelise iimveliso zefilimu ze-calendered ezikumgangatho ophezulu.
