Hlola Ukuthi Izinkomishi Zepulasitiki Empilweni Zenziwa Kanjani

Izinkomishi zepulasitiki azikwazi ukwenziwa ngaphandle kwamapulasitiki. Kudingeka siqonde amapulasitiki ekuqaleni.

Yenziwa kanjani ipulasitiki?

Indlela okwenziwa ngayo ipulasitiki incike kakhulu ekutheni yiluphi uhlobo lwepulasitiki olusetshenziselwa izinkomishi zepulasitiki. Ngakho-ke ake siqale ngokudabula izinhlobo ezintathu ezahlukene zepulasitiki ezisetshenziselwa ukwenza izinkomishi zepulasitiki. Izinhlobo ezintathu ezahlukene zepulasitiki yi-PET, i-rPET ne-PLA plastic.

A. Ipulasitiki ye-PET

I-PET imele i-polyethylene terephthalate, okuwuhlobo oluvame kakhulu lwepulasitiki. I-PET iyinhlaka ye-thermoplastic polymer evame kakhulu yomndeni we-polyester futhi isetshenziselwa imicu yezingubo, iziqukathi zoketshezi nokudla, kanye ne-thermoforming yokukhiqiza, futhi ihlanganiswe ne-glass fiber ye-resin yobunjiniyela.Isetshenziselwa ikakhulukazi amabhodlela futhi iguquguquka kakhudlwana. izinto zepulasitiki njengoba ziqinile ngempela, futhi uma ziqoqwe ngendlela efanele zingagaywa kabusha futhi zisetshenziselwe enye i-rPET. Kubuye kube yizinto ezisetshenziswa kakhulu ekwenzeni izinkomishi zepulasitiki ngoba ziningi, futhi zivunyelwe ukuthi zithintane nezinto zokudla.

Ipulasitiki yenziwe ngamafutha eNaphtha okuyingxenyana yamafutha aluhlaza, lokhu kwenziwa ngesikhathi sokucwengwa lapho amafutha ehlukana abe yiNaphtha, Hydrogen nezinye izingxenyana. Uwoyela okhishwa iNaphtha ube usuphenduka ipulasitiki ngenqubo ebizwa ngePolymerization. Inqubo ixhuma i-ethylene ne-propylene ukuze kwakhiwe amaketanga e-polymer okuyinto ekugcineni i-PET plastic eyenziwe ngayo.

B. ipulasitiki ye-rPET

I-rPET imele i-polyethylene terephthalate egaywe kabusha, futhi iwuhlobo olusetshenziswa kakhulu lwepulasitiki egaywe kabusha, ngoba ukuqina kwe-PET kwenza kube lula ukugaywa kabusha futhi kusaqinisekisa izinga eliphezulu. I-PET egaywe kabusha isiba uhlobo olusetshenziswa kabanzi lukajenene wepulasitiki, futhi izinkampani eziningi kakhulu zizama ukwenza imikhiqizo yazo nge-rPET esikhundleni se-PET evamile. Lokhu ikakhulukazi imboni yezokwakha, lapho amafasitela amaningi enziwa ngepulasitiki ye-rPET. Kungase futhi kube uhlaka lwezibuko.

C. PLA plastic

Ipulasitiki ye-PLA iyi-polyester ekhiqizwa izinto ezisekelwe ezitshalweni ezifana nesitashi sommbila noma umoba. Lapho usebenzisa lokhu ukukhiqiza ipulasitiki ye-PLA kukhona izinyathelo ezimbalwa. Izinto ezisetshenziswayo zidlula ekugayweni okumanzi, lapho isitashi sihlukaniswa khona nezinye izinto ezikhishwa esitshalweni. Isitashi sibe sesihlanganiswa ne-asidi noma ama-enzyme futhi ekugcineni siyashisisa. Isitashi sommbila sizoba yi-D-glucose, bese sidlulela enqubweni yokuvutshelwa okuzoyiguqula ibe yi-Lactic Acid.
I-PLA isiphenduke into edumile ngenxa yokuthi ikhiqizwa ngokwezomnotho ngezinsiza ezivuselelekayo. Ukusetshenziswa kwayo okusabalele kuvinjwe ukushiyeka okuningi ngokomzimba nokucubungula.

Zenziwa kanjani izinkomishi zepulasitiki?

Uma kukhulunywa ngezinkomishi zepulasitiki nokuthi izinkomishi zepulasitiki zenziwa kanjani empeleni kwenza umehluko uma zilahlwa noma zisebenziseka kabusha izinkomishi zepulasitiki. Izinkomishi zepulasitiki zenziwe nge-polyethylene terephthalate, noma i-PET, ipulasitiki ye-polyester ehlala isikhathi eside emelana nokushisa nokubanda futhi imelana kahle nokuqhekeka. Ngenqubo eyaziwa ngokuthi i-injection molding, i-PET ixutshwa njengoketshezi, ijovelwe ezibunjeni ezimise okwenkomishi bese ipholiswa futhi iqiniswe.

Izinkomishi zepulasitiki zenziwa ngenqubo ebizwa ngokuthi i-injection molding, lapho izinto zepulasitiki zixutshwa noketshezi bese zifakwa esifanekisweni sezinkomishi zepulasitiki, ezinquma ubukhulu nokuqina kwezinkomishi.

Ngakho-ke ukuthi yiziphi izinkomishi zepulasitiki ezenziwe njengezilahlwayo noma ezisebenzisekayo kabusha kuya ngezifanekiso

abakhiqizi bemishini yepulasitiki ye-thermoforming isebenzisa.

I-Gtmsmart Plastic Cup Thermoforming MachineIkakhulukazi ukukhiqizwa kweziqukathi zepulasitiki ezihlukahlukene (izinkomishi ze-jelly, izinkomishi zokuphuza, izitsha zephakheji, njll) ezinamashidi e-thermoplastic, njenge-PP, i-PET, i-PE, i-PS, i-HIPS, i-PLA, njll..

Iumshini wokwenza inkomishi yepulasitiki  ilawulwa yi-hydraulic kanye ne-servo, nge-inverter sheet feeding, isistimu eqhutshwa yi-hydraulic, i-servo stretching, lokhu kuyenza ibe nokusebenza okuzinzile nokuqeda umkhiqizo ngekhwalithi ephezulu. Ikakhulukazi ukukhiqizwa kweziqukathi zepulasitiki ezihlukene ezinokujula okwenziwe ≤180mm (izinkomishi ze-jelly, izinkomishi zokuphuza, izitsha zephakheji, njll) ezinamashidi ashisayo, njenge-PP, i-PET, i-PE, i-PS, i-HIPS, i-PLA, njll.
