Kodi Filimu Yophimba Polypropylene Yozungulira M'mbali mwa M'mimba N'chiyani?
Filimu ya polypropylene (BOPP) yokhazikika pa biaxially ndi mtundu wa filimu yokhazikika yosinthasintha. Filimu yozungulira ya polypropylene yokhazikika pa biaxially imatambasulidwa mumakina ndi mbali zopingasa. Izi zimapangitsa kuti pakhale mawonekedwe a molekyulu mbali zonse ziwiri. Mtundu uwu wa filimu yokhazikika yokhazikika imapangidwa kudzera mu njira yopangira tubular. Buluu wa filimu wooneka ngati chubu umatenthedwa ndikutenthedwa mpaka pamalo ake ofewa (izi ndizosiyana ndi malo osungunuka) ndipo umatambasulidwa ndi makina. Filimuyo imatambasulidwa pakati pa 300% - 400%. Kapenanso, filimuyo imatha kutambasulidwa ndi njira yotchedwa tenter-frame film manufacturing. Ndi njira iyi, ma polima amatulutsidwa pa mpukutu wozizira (womwe umadziwikanso kuti base sheet) ndikukokedwa motsatira njira ya makina. Tenter-frame film imatipanga... -
