Siyini isikhwama seplastiki sokupakisha

Isikhwama sokupakisha sePlastiki siwuhlobo lwesikhwama sokupakisha esisebenzisa ipulasitiki njengempahla eluhlaza ukukhiqiza izihloko ezahlukahlukene empilweni yansuku zonke.Isetshenziswa kabanzi ekuphileni kwansuku zonke kanye nokukhiqizwa kwezimboni, kodwa ukukhululeka ngalesi sikhathi kuletha ukulimala kwesikhathi eside.Izikhwama zokupakisha zepulasitiki ezisetshenziswa kakhulu ngokuvamile zenziwe ngefilimu ye-polyethylene, engeyona enobuthi futhi engasetshenziswa ukubamba ukudla.Kukhona futhi uhlobo lwefilimu eyenziwe nge-polyvinyl chloride, nayo engeyona enobuthi, kodwa izithasiselo ezengezwe ngokwenhloso yefilimu zivame ukulimaza emzimbeni womuntu futhi zinezinga elithile lobuthi.Ngakho-ke, lolu hlobo lwefilimu nezikhwama zepulasitiki ezenziwe ngefilimu azifanele ukubamba ukudla.

Izikhwama zokupakisha zepulasitiki zingahlukaniswa zibe yi-OPP, i-CPP, i-PP, i-PE, i-PVA, i-EVA, izikhwama eziyinhlanganisela, izikhwama ze-co-extrusion, njll ngokusho kwezinto zabo.

Izinzuzo
I-CPP
Ayinabuthi, iyahlanganiswa, ingcono ekukhanyeni kune-PE, futhi ingaphansi kancane ngobulukhuni.Ukuthungwa kuthambile, ngokusobala kwe-PP kanye nokuthamba kwe-PE.
PP
Ukuqina kungaphansi kwe-OPP, bunganwetshwa (ukunwetshwa ngezindlela ezimbili) ngemuva kokwelulelwa kunxantathu, uphawu olungezansi noma uphawu oluseceleni.
PE
Kukhona i-formalin, kodwa ukungafihli lutho kubi kancane
I-PVA
Ukuthungwa okuthambile nokucaca okuhle.Iwuhlobo olusha lwempahla ehambisana nemvelo.Iyancibilika emanzini.Izinto zokusetshenziswa zingeniswa zivela eJapan.Intengo iyabiza.Isetshenziswa kabanzi emazweni angaphandle.
I-OPP
Ukucaca okuhle nobulukhuni obuqinile
Isikhwama esiyinhlanganisela
Isigxivizo siqinile, siyaphrinta, futhi uyinki ngeke uwe
Isikhwama se-co-extrusion
Ukucaca okuhle, ukuthungwa okuthambile, okuphrintekayo

Izikhwama zokupakisha zepulasitiki zingahlukaniswa zibe izakhiwo ezihlukene zomkhiqizo kanye nokusetshenziswa: izikhwama zepulasitiki ezilukiweyo nezikhwama zefilimu zepulasitiki.
Isikhwama esilukiwe
Izikhwama zepulasitiki ezilukiwe zakhiwa izikhwama ze-polypropylene nezikhwama ze-polyethylene ngokusho kwezinto eziyinhloko;
Ngokwendlela yokuthunga, ihlukaniswe yaba izikhwama ezingezansi ezinemithungo kanye nezikhwama ezingaphansi ezinemithungo.
Isetshenziswa kabanzi njengento yokupakisha umanyolo, imikhiqizo yamakhemikhali nezinye izinto.Inqubo yokukhiqiza eyinhloko ukusebenzisa izinto zokusetshenziswa zepulasitiki ukukhipha ifilimu, ukusika, nokunwebeka ngokulinganayo kube imicu eyisicaba, bese weluka imikhiqizo ngokusebenzisa i-warp ne-weft, ngokuvamile ebizwa ngokuthi izikhwama ezilukiweyo.
Izici: isisindo esilula, amandla aphezulu, ukumelana nokugqwala, njll., ngemva kokwengeza umugqa wefilimu wepulasitiki, kungaba umswakama-ubufakazi nomswakama-ubufakazi;Isikhwama esincane singaphansi kuka-2.5kg, isikhwama esiphakathi nendawo singu-25-50kg, isikhwama esisindayo singu-50-100kg
Isikhwama sefilimu
Impahla eluhlaza yezikhwama zefilimu yepulasitiki i-polyethylene.Izikhwama zepulasitiki zilethe ngempela ukuphila kwethu kalula, kodwa ukuba lula ngalesi sikhathi kulethe ukulimala kwesikhathi eside.
Kuhlukaniswa ngezinto zokukhiqiza: izikhwama zepulasitiki ezinengcindezi ephezulu ye-polyethylene, izikhwama zepulasitiki ze-polyethylene ezinengcindezi ephansi, izikhwama zepulasitiki ze-polypropylene, izikhwama zepulasitiki ze-polyvinyl chloride, njll.
Kuhlukaniswa ngokubukeka: Isikhwama sesikibha, isikhwama esiqondile.Izikhwama ezivaliwe, izikhwama zepulasitiki, izikhwama ezimise okukhethekile, njll.
Izici: Izikhwama ezilula zilayisha ngaphezu kwe-1kg;izikhwama medium umthwalo 1-10kg;izikhwama ezinzima umthwalo 10-30kg;izikhwama zeziqukathi zilayisha ngaphezu kuka-1000kg.
