Ngokusho kwezinto ezisetshenziswa ekukhiqizeni ifilimu ye-polyester kanye nokuhlukaniswa kwenqubo yokukhiqiza.

Ngokusho kwezinto zokusetshenziswa ezihlukene kanye nezinqubo zokudweba ezisetshenziswa ekukhiqizeni ifilimu ye-polyester zingahlukaniswa zibe izinhlobo ezimbili ezilandelayo.

1. Ifilimu ye-Bidirectional Stretch Polyester (BOPET)

Ifilimu evamile ye-BOPET ukusetshenziswa kwezinto ezikhanyayo (eyaziwa nangokuthi impahla enkulu yokukhanya, okungukuthi, okuqukethwe kwe-polyester chip titanium dioxide engu-0.1%, ngemva kokomiswa, ukuncibilika, ukukhishwa, ukuphonsa kanye nokwelula okuqondile nokuvundlile kwefilimu yezinga eliphezulu. , esetshenziswa kabanzi).Ifilimu ye-BOPET inezici zamandla aphezulu, ukuqina okuhle, ukucaca kanye nokucwebezela okuphezulu.Ayinaphunga, ayinambitheki, ayinambala, ayinabo ubuthi, amandla avelele nokuqina;Amandla ayo aqinile izikhathi ezi-3 kunefilimu ye-PC, ifilimu ye-nylon, amandla omthelela angama-3 kuya ku-5 izikhathi zefilimu ye-BOPP, inokumelana okuhle kakhulu kokugqoka, ukumelana nokugoqa, ukumelana ne-pinhole kanye nokumelana nokukhala;Ukuncipha okushisayo kuncane kakhulu, ku-120℃, kuphela ukuncipha okungu-1.25% ngemuva kwemizuzu eyi-15;Inesakhiwo esihle se-antistatic, i-vacuum aluminization elula, futhi ingagcotshwa nge-PVDC ukuze ithuthukise ukuvala ukushisa kwayo, indawo yokuvimbela kanye nokunamathela kokuphrinta;I-BOPET futhi inokumelana nokushisa okuhle, ukumelana nokupheka okuhle kakhulu, ukumelana nezinga lokushisa eliphansi lokuqandisa, ukumelana nowoyela okuhle nokumelana namakhemikhali.Ifilimu ye-BOPET ngaphezu kwe-nitrobenzene, i-chloroform, i-benzyl utshwala, amakhemikhali amaningi awakwazi ukuwenza ahlakazeke.Kodwa-ke, i-BOPET izogugulwa yi-alkali enamandla, futhi kufanele inakwe lapho usebenzisa.Ifilimu ye-BOPET inokumuncwa okuphansi kwamanzi, ukumelana namanzi okuhle, futhi ifanele ukupakisha ukudla okunokuqukethwe kwamanzi amaningi.

2. Ifilimu ye-Unidirectional Stretch Polyester (CPET)

Ifilimu evamile ye-CPET iwukusetshenziswa kwezinto ezibonakalayo zokuhlanganisa (i-polyester chips eluhlaza engeza i-titanium dioxide), ngemva kokomiswa, ukuncibilika, ukukhishwa, ukukhishwa kanye nokwelula isikhathi eside kwefilimu, ibanga eliphansi kanye nenani lefilimu ye-polyester, esetshenziselwa ithebhulethi yezemithi. ukupakisha.Ngenxa yokusetshenziswa kokuncane, abakhiqizi abakhiqiza ukukhiqizwa okuncane kakhulu, okubalelwa ku-5% wenkundla yefilimu ye-polyester, amabhizinisi aseShayina nawo awangeniswanga ngaphandle, ubukhulu obujwayelekile be-150μm.
