Zvinoenderana nemidziyo inoshandiswa mukugadzira firimu repolyester uye maitiro ekugadzira maitiro.

Zvinoenderana neakasiyana mbishi uye maitiro ekudhirowa anoshandiswa mukugadzirwa kwepolyester firimu anogona kukamurwa kuva maviri anotevera marudzi.

1. Bidirectional Stretch Polyester film (BOPET)

General BOPET firimu kushandiswa kwezvinhu zvakareruka (zvinozivikanwawo sezvinhu zvakakura zvemwenje, kureva, iyo mbishi polyester chip titanium dioxide yemukati me0.1%, mushure mekuomesa, kunyunguduka, extrusion, kukanda uye kutwasuka uye kuchinjika kutambanudza kwepamusoro-giredhi firimu. , inoshandiswa zvakanyanya).BOPET firimu rine hunhu hwekusimba kwepamusoro, kusimba kwakanaka, kujeka uye kupenya kwakanyanya.Kusanhuhwirira, kusinganakidze, kusina ruvara, kusina chepfu, kusimba kunoshamisa uye kuoma;Simba rayo rekusimba ndeye 3 nguva yePC firimu, firimu renaironi, simba rekuita ndeye 3 kusvika ku5 nguva yeBOPP firimu, ine yakanakisa kupfeka kusagadzikana, kupeta kuramba, pinhole kuramba uye kubvarura kuramba;The thermal shrinkage idiki kwazvo, pa120 ℃, chete 1.25% shrinkage mushure me15min;Iine yakanaka antistatic pfuma, nyore kupukuta aluminization, uye inogona kuvharidzirwa nePVDC kuti ivandudze kupisa kwayo kuvharwa, chipingamupinyi pfuma uye kudhinda kunamatira;BOPET zvakare ine yakanaka yekudzivirira kupisa, yakanakisa yekubika kuramba, yakaderera tembiricha yechando kuramba, yakanaka mafuta kuramba uye makemikari kuramba.BOPET firimu mukuwedzera kune nitrobenzene, chloroform, benzyl doro, makemikari mazhinji haagone kuita kuti inyunguduke.Nekudaro, BOPET ichabviswa nealkali yakasimba, uye inofanirwa kutariswa kana uchishandisa.BOPET firimu rine yakaderera mvura kunyura, yakanaka kuramba mvura, uye inokodzera kurongedza chikafu chine yakakwira mvura.

2. Unidirectional Stretch Polyester Firimu (CPET)

General CPET firimu iko kushandiswa kwesemi-matting material (raw material polyester chips inowedzera titanium dioxide), mushure mekuoma, kunyunguduka, extrusion, kukanda uye kureba kutambanudza kwefirimu, yakaderera giredhi uye mutengo mupolyester firimu, inonyanya kushandiswa piritsi remishonga. kurongedza.Nekuda kwekushandisa kushoma, vanogadzira kushoma-akawanda-akawanda kugadzirwa, achiverengera inosvika 5% yenzvimbo yemafirimu epolyester, mabhizinesi eChinese zvakare haatengeswe kunze kwenyika, chiyero chakakora che150μm.
