Iikomityi zeplastiki azinakwenziwa ngaphandle kweeplastiki. Kufuneka siqonde iiplastiki ekuqaleni.
Yenziwa njani iplastiki?
Indlela eyenziwe ngayo iplastiki ixhomekeke kakhulu ekubeni loluphi uhlobo lweplastiki olusetyenziswa kwiikomityi zeplastiki. Ngoko ke masiqale ngokudlula kwiindidi ezintathu ezahlukeneyo zeplastiki ezisetyenziselwa ukwenza iikomityi zeplastiki. Iindidi ezintathu ezahlukeneyo zeplastiki yi-PET, i-rPET kunye neplastiki ye-PLA.
A. PET iplastiki
I-PET imele i-polyethylene terephthalate, lolona hlobo luxhaphakileyo lweplastiki. I-PET yeyona nto ixhaphakileyo kwi-polymer resin ye-thermoplastic yosapho lwe-polyester kwaye isetyenziselwa iintsinga zempahla, izikhongozeli zolwelo kunye nokutya, kunye ne-thermoforming yokuvelisa, kunye nokudityaniswa nefiber yeglasi yobunjineli beresin.Isetyenziswa ngakumbi kwiibhotile kwaye iguquguquka ngakumbi. imathiriyeli yeplastiki kuba yomelele ngokwenene, kwaye ukuba iqokelelwe ngokuchanekileyo inokuhlaziywa kwakhona kwaye isetyenziselwe enye i-rPET. Ikwayeyona nto isetyenziswa kakhulu ekwenzeni iikomityi zeplastiki kuba kukho unikezelo olukhulu, kwaye ivunyiwe ukuba idibane nezinto zokutya.
Iplastiki yenziwe kwioli yeNaphtha eyingxenye yeoli ekrwada, oku kwenziwa ngexesha lokucoca apho ioli iyahlukana ibe yiNaphtha, iHydrogen kunye nezinye iinqununu. Isicatshulwa se-oyile iNaphtha emva koko ibe yiplastiki ngenkqubo ebizwa ngokuba yiPolymerization. Inkqubo idibanisa i-ethylene kunye nepropylene ukwenza i-polymer chains ekugqibeleni yiyiphi iplastiki ye-PET eyenziwe ngayo.
B. iplastiki ye-rPET
I-rPET imele i-recycled polyethylene terephthalate, kwaye lolona hlobo lusetyenziswa ngokuqhelekileyo lweplastiki esetyenzisiweyo, kuba ukuqina kwe-PET kwenza kube lula ukurisayikilishwa kwaye kusenokuqinisekisa umgangatho ophezulu. I-PET ehlaziyiweyo isiba luhlobo olusetyenziswa ngokubanzi lweplastiki ngokubanzi, kwaye iinkampani ezininzi ngakumbi zizama ukwenza iimveliso zazo kwi-rPET endaweni ye-PET eqhelekileyo. Oku ngakumbi ishishini lokwakha, apho iifestile ezininzi zenziwe ngeplastiki ye-rPET. Isenokuba sisakhelo seendondo.
C. PLA iplastiki
Iplastiki yePLA yipolyester eveliswa ngezinto ezisekelwe kwizityalo ezifana nesitatshi sombona okanye umoba. Xa usebenzisa oku ukuvelisa iplastiki ye-PLA kukho amanyathelo ambalwa. Izinto ezisetyenzisiweyo zihamba ngokusila okumanzi, apho isitashi sihlukana nazo zonke ezinye izinto ezitsalwa kwizinto zesityalo. Istatshi sixutywa neasidi okanye i-enzymes kwaye ekugqibeleni sifudunyezwe. Isitatshi sombona siya kuba yi-D-glucose, kwaye emva koko sidlule kwinkqubo yokuvubela eya kuthi isijike sibe yiLactic Acid.
I-PLA iye yaba yinto ethandwayo ngenxa yokuba iveliswe ngokwezoqoqosho kwimithombo evuselelekayo. Ukusetyenziswa kwayo ngokubanzi kuye kwathintelwa ziziphene ezininzi zomzimba kunye nokucubungula.
Zenziwa njani iikomityi zeplastiki?
Xa kuziwa kwiikomityi zeplastiki kunye nokuba zenziwe njani iikomityi zeplastiki ngokwenene yenza umahluko ukuba ziyalahlwa okanye ziphinde zisetyenziswe iikomityi zeplastiki. Iikomityi zeplastiki zenziwe nge-polyethylene terephthalate, okanye i-PET, iplastiki ye-polyester ehlala ixesha elide exhathisa amaqondo obushushu ashushu kunye nabandayo kwaye iyakwazi ukumelana nokuqhekeka. Ngenkqubo eyaziwa ngokuba kukubumba inaliti, i-PET ixutywa njengolwelo, igalelwe kubumba obumise okwekomityi emva koko yapholiswa yaqina.
Iikomityi zeplastiki zenziwe ngenkqubo ebizwa ngokuba yi-injection molding, apho izinto zeplastiki zixutywa kunye nolwelo kwaye zifakwe kwi-template yeekomityi zeplastiki, ezimisela ubungakanani kunye nobukhulu beekomityi.
Ke yeyiphi impembelelo yokuba iikomityi zeplastiki zenziwe njengento enokulahlwa okanye enokuphinda isetyenziswe ixhomekeke kwiitemplates
abavelisi beplastiki be-thermoforming machine usebenzisa.
Gtmsmart Umatshini wePlastiki weThermoforming MachineIkakhulu isenzelwa ukuveliswa kwezikhongozeli zeplastiki ezahlukahlukeneyo (iikomityi zejeli, iikomityi zokusela, izikhongozeli zepakethe, njl.njl.
Iumatshini wokwenza ikomityi yeplastiki ilawulwa yi-hydraulic kunye ne-servo, kunye ne-inverter sheet feeding, i-hydraulic driven system, i-servo stretching, ezi zenza ukuba zibe nokusebenza okuzinzile kunye nokugqiba imveliso enomgangatho ophezulu. Ikakhulu ukwenzela ukuveliswa kwezikhongozeli zeplastiki ezahlukeneyo ezinobunzulu obuyi-≤180mm (iikomityi zejeli, iikomityi zokusela, izikhongozeli zepakethe, njl.njl) ezinamashiti ashushu, njengePP, PET, PE, PS, HIPS, PLA, njl.
