Ifilimu Yokupakisha Yezokwelapha Elula Ye-PA/PE Enezingqimba Eziyi-11

Ifilimu ye-HSQY enezingqimba ezingu-11 ze-PA/PE co-extrusion iyifilimu yokupakisha ecacile, ephrintekayo enezingqimba eziningi ebekwe kumaphrojekthi okupakisha amadivayisi ezokwelapha kanye nezindwangu zezokwelapha ezidinga ukuvikelwa komshini, ukumelana nokubhoboza, ukuvalwa kokushisa kanye nokuvulwa okulula okulawulwayo.

Imininingwane yomkhiqizo yamanje ibala uhlelo lwezinto ze-PA + PE, ubukhulu obusukela ku-0.03mm kuya ku-0.45mm kanye nobubanzi bokugoqa obusukela ku-200mm kuya ku-4000mm. I-PA inikela ngokuqina komshini kanye nokumelana nokubhoboza, kuyilapho i-PE isekela ukuguquguquka, ukumelana nomswakama kanye nokusebenza kokuvala ukushisa.

Lo mkhiqizo uthengiswa njengefilimu yokufaka yezokwelapha ehlutshulwa kalula. Amandla angempela okuhlutshulwa, amandla okuvala kanye nokuziphatha kokuvula kuncike ebangeni eliqondile lefilimu, isisekelo sokuvala esiphambene, izinga lokushisa lokuvala, ingcindezi kanye nesikhathi sokuhlala. Ngakho-ke uhlelo lokupakisha oluqediwe kufanele luhlolwe ngaphansi kwezimo zangempela zokupakisha kanye nokubulala amagciwane zekhasimende.

Imininingwane yefilimu yezokwelapha ye-PA/PE enezingqimba ezingu-11

Okubalulekile: Umthombo wamanje we-HSQY awushicileli uchungechunge oluqondile lwezingqimba eziyi-11, i-OTR, i-WVTR, amandla okuhluba, amandla okuvala, ifasitela lokuvala, ukuhambisana kokubulala inzalo, ububanzi be-roll core, i-OD ephezulu ye-roll noma idatha yokuqinisekiswa kokupakishwa kwezokwelapha. Lawa manani kufanele atholakale ngebanga eliqondile lefilimu ngaphambi kokuba lichazwe ohlelweni lokupakishwa kwezokwelapha oluqinisekisiwe.

Indlela i-PA ne-PE ezisebenza ngayo kwifilimu yokupakishwa kwezokwelapha

I-PA ne-PE zinikeza imisebenzi ehlukene ngaphakathi kwesakhiwo esihlanganisiwe esinezingqimba eziningi. Ukuhlelwa kwengqimba okuqondile kungahluka ngokuya ngebanga lefilimu elidingekayo, ngakho-ke ukwakhiwa kokugcina kufanele kuqinisekiswe ngedatha yobuchwepheshe esebenzayo impahla yeshidi .

Kungani Kufanele Usebenzise Isakhiwo Sokunwebeka Esinezingqimba Eziyi-11?

Inqubo yokukhipha i-co-extrusion enezingqimba eziningi ivumela izendlalelo ezahlukene ze-polymer ukuthi zenze imisebenzi ehlukene yemishini, isithiyo, ukuvala kanye nokucubungula ngaphakathi kwefilimu eyodwa eguquguqukayo.

Ngokupakishwa kwezokwelapha, lokhu kungavumela umklami wefilimu ukuthi alinganisele ukumelana nokubhoboza, ukuguquguquka, ukuvaleka, ukucaca kanye nokuguqula ukusebenza ngokuya ngomkhiqizo wezokwelapha kanye nemishini yokupakisha.

Ibinzana elithi 'izingqimba ezingu-11' akufanele lisetshenziswe ukuphetha ngokulandelana kwezingqimba ezithile ngaphandle kokuthi lokho kulandelana kuqinisekisiwe ngebanga lefilimu elinikeziwe. Abathengi abadinga ukwakhiwa okuchaziwe kufanele bacele isakhiwo esiphelele sezingqimba kanye nesimemezelo sezinto.

Ifilimu Yokupakisha Yezokwelapha Elula Kalula

Ukuhlubuka okulula emaphaketheni ezokwelapha kufanele kuhlinzeke ngokuvulwa okulawulwayo ngaphandle kokwenza uphawu lwephakheji lube buthaka ngokungadingekile ngesikhathi sokukhiqiza, ukusatshalaliswa noma ukugcinwa.

Ukuziphatha kwangempela kwe-peel kudalwe yi-interface ephelele ye-seal. Ukwakheka kwefilimu, i-substrate yokuvala ephambene, izinga lokushisa kwe-seal, ingcindezi, isikhathi sokuhlala kanye ne-geometry yephakheji konke kungathonya amandla e-peel kanye nekhwalithi yokuvula.

Ngakho-ke abathengi bokupakisha kwezokwelapha kufanele bacacise ukuthi badinga ukuhlubuka okulula, ukuhlubuka okulawulwayo noma esinye isici sokuvula futhi banikeze isisekelo esiqondile ifilimu ezovalwa kuso.
