1).Isantya semveliso yomgca wokuvelisa ifilim we-extrusion siphezulu kunendlela yefilimu evuthelweyo, enokuthi ibe phezulu njenge-300m/min, ngelixa indlela yefilimu evuthelweyo iba yi-30-60m/min kuphela ngenxa yokuthintelwa kokupholisa. isantya sefilimu yeqamza.Ubushushu be-roller ephakathi yokupholisa ingaba ngu-0-5 ℃, kwaye ifakwe ngokuthe ngqo kwi-roller, kwaye umphumo wokupholisa ulungile.
2).Ukucaca kwefilimu ye-extrusion cast kungcono kunendlela yefilimu evuthelweyo.Ingaba yi-PE okanye i-pp, inokuvelisa ifilimu ngokubonakala kakuhle ngendlela yokukhupha i-extrusion.Nangona kunjalo, xa indlela yokuvuthela ifilimu ipholile emoyeni, i-p ayinakuba nokucaca okulungileyo.Ukufumana ukungafihli kakuhle, indlela yokupholisa amanzi kufuneka isetyenziswe.
3).Ubukhulu obufanayo bendlela yokuphosa i-extrusion ingcono kunendlela yefilimu evuthelweyo.
4).Iipropati zexesha elide kunye ne-transverse ye-extrusion cast film i-balanced, ngelixa i-longitudinal kunye ne-transverse iimpawu zefilimu evuthelweyo zihluke ngenxa yokwahlukana kwesantya se-traction roller kunye ne-inflation ratio.Ngokomgaqo, ifilimu eveliswa yindlela yokukhupha i-extrusion idluliselwa ukusuka komnye umqulu ukuya kwenye ngaphandle koxinzelelo lokujikeleza okanye ukutsalwa, ngoko ke ifilimu yokuphosa i-extrusion ayinwebekiyo kwi-longitudinal okanye i-transverse direction, kunye nokusebenza ngokulinganayo.
