Isixazululo esihle kakhulu sokupakisha sokudla kwesilwane esingu-15KG

Izikhwama ze-gusset eziseceleni zinezingqimba ezimbalwa zamafilimu epulasitiki. Uma ukhetha izinto ezibonakalayo, inselele enkulu yokupakisha ukudla kwezinja ezinesisindo esisindayo esingu-15KG ukuqina kwesikhwama sokupakisha, ngakho-ke ekukhethweni kwezinto ezibonakalayo, kuyadingeka khetha ifilimu lepulasitiki elinamandla angcono okuqina kanye nokuqina.
Okulandelayo ukuqhathanisa amandla aqinile amanye amafilimu epulasitiki asetshenziswa kakhulu:
I-PET (i-polyethylene terephthalate):Amandla okuqina: 60-90 MPaUbude besikhathi sokuphumula: 15-50%

I-PA (polyamide):Amandla okuqina: 80-120 MPaUbude besikhathi sokuphumula: 20-50%

I-AL (i-aluminium foil):Amandla okuqina: 60-150 MPaUbude besikhathi sokuphumula: 1-5%

I-PE (i-polyethylene):Amandla okuqina: 10-25 MPaUbude besikhathi sokuphumula: 200-1000%

I-PP (i-polypropylene):Amandla okuqina: 30-50 MPaUbude besikhathi sokuphumula: 100-600%

I-PVC (i-polyvinyl chloride):Amandla okuqina: 40-70 MPaUbude besikhathi sokuphumula: 10-100%

I-PS (i-polystyrene):Amandla okuqina: 50-70 MPaUbude besikhathi sokuphumula: 1-3%

I-ABS (acrylonitrile-butadiene-styrene):Amandla okuqina: 40-70 MPaUbude besikhathi sokuphumula: 5-50%

I-PC (i-polycarbonate):Amandla okuqina: 55-75 MPaUbude besikhathi sokuphumula: 80-150%

Ngokusobala, i-PA iyimpahla enokuqina okuhle kakhulu, futhi ibalulekile lapho upakisha ukudla kwezinja ezinesisindo esikhulu.Ngaphezu kwalokho, singase futhi sandise ubukhulu bezikhwama ukuze sithuthukise ukuqina kwezikhwama.

Futhi impahla yokuvimbela ibalulekile ekupakisheni ukudla kwezilwane ezifuywayo imbangela pet imikhiqizo yokudla ingakonakala ngokushesha futhi ingcoliswe uma ihlangana nomswakama.Isikhwama sokupakisha esinezici ezinhle zokuvimbela singasiza ukuvikela ukudla kwesilwane esifuywayo emswakama ngokukuvimbaengena esikhwameni.FuthiUmoya-mpilo ungaholela futhi ekulimaleni kwemikhiqizo yokudla kwezilwane ezifuywayo, ikakhulukazi leyo equkethe amafutha namafutha.Izakhiwo zokuvimbela zingavimbela umoya-mpilo ukuthi ungangeni emaphaketheni futhi uhlangane nokudla kwesilwane, ngaleyo ndlelaukwelula impilo yeshalofu layo.Izakhiwo zokuvimbela zingasiza ekuvimbeleni ukudluliswa kwephunga nokunambitheka phakathi kokudla kwesilwane esifuywayo kanye nokupakishwa kwayo.Lokhu kubalulekile ngoba izilwane ezifuywayo zingazwela kakhulu ekushintsheni ukunambitheka nephungaukudla kwabo.Ukuchayeka ekukhanyeni kungabangela ukuthi imikhiqizo yokudla kwezilwane ezifuywayo yonane futhi ilahlekelwe ukondleka.Izakhiwo zokuvimbela zingavimbela ukukhanya ukuthi kungangeni ephaketheni futhi kulimaze ukudla kwesilwane esifuywayo.

Ngakho-ke khetha impahla efanele ukuze uthole impahla yokuvimbela engcono nayo ibaluleke kakhulu.

Bese-ke ukuthi hlobo luni lwempahla enempahla engcono yokuvimbela, nalu uhlu lwedatha yesakhiwo sokuvimbela amanye amafilimu epulasitiki adumile:

I-Polyethylene (PE): I-PE inezakhiwo ezingezinhle zokuvimbela futhi ayivimbeli ukudlula kwamagesi noma uketshezi, okwenza kungafaneleki ukufakwa kwezicelo ezidinga izinga eliphezulu lokuvikelwa kwesithiyo.

I-Polyethylene terephthalate (PET): I-PET inezindawo ezinhle kakhulu zokuvimbela futhi ingavimbela ukudlula kwamagesi amaningi, uketshezi, kanye nephunga.Ivame ukusetshenziswa ekufakweni kwesiphuzo nokudla, kanye nezicelo zezokwelapha nezemithi.

I-Polypropylene (PP): I-PP inezakhiwo ezingcono zokuvimba kune-PE, kodwa namanje ayinikezi izinga eliphezulu lokuvikela kumagesi noma uketshezi.Ivame ukusetshenziswa ezinhlelweni zokupakisha lapho izinga eliphansi lokuvikela isithiyo likhona
okudingekayo.

I-Polyamide (PA), eyaziwa nangokuthi inayiloni: I-PA inezindawo ezinhle zokuvimbela futhi ingavimbela ukudlula kwamagesi amaningi noketshezi, kodwa ayisebenzi kahle ekuvimbeni iphunga.Kuvame ukusetshenziswa ezinhlelweni ezidinga amandla aphezulu futhi
ukuqina, njengezingxenye zikagesi neze-elekthronikhi.

I-Aluminium (AL): I-Aluminium iyisivimbeli esihle kakhulu futhi ingavimbela ukudlula kwamagesi amaningi, uketshezi, namaphunga.Ivame ukusetshenziswa ekufakweni kokudla kanye nezicelo zezokwelapha ngenxa yezakhiwo zayo zokuvinjelwa okuphezulu futhi zinhle kakhulu
ukumelana nokushisa nomswakama.

I-Vacuum metalized polyethylene terephthalate (VMPET): I-VMPET iyimpahla elayiniwe ehlanganisa i-PET ne-aluminium ukuze inikeze umgoqo omuhle kakhulu ngokumelene namagesi, uketshezi, kanye nephunga.Isetshenziswa kakhulu ekupakishweni kokudla okune-barrier ephezulu kanye
izicelo zezokwelapha.

Iphepha: Iphepha linezithiyo ezimbi futhi alivimbeli ukudlula kwamagesi, uketshezi, noma iphunga.Ivamise ukusetshenziswa ezinhlelweni lapho kudingeka izinga eliphansi lokuvikela izithiyo, njengokuphrinta kwephephandaba nomagazini.

Ngakho-ke ngokusobala i-aluminiyamu iyimpahla engcono kakhulu yokuvimbela impahla, kodwa ngokuvamile sizosebenzisa ipulasitiki ye-aluminium foil esikhundleni se-aluminium ukuze songe izindleko okwamanje uthole impahla ephezulu yokuvimbela.
