Ukukhethwa kweMathiriyeli ekrwada kunye noLungiselelo
Imibhobho yePlastiki iqhele ukwenziwa kwizinto ezifana nePVC, PE, kunye nePP. Izinto ezifanelekileyo kufuneka zikhethwe ngokusekelwe kusetyenziso olucetywayo. Xa ukhetha imathiriyeli ekrwada, izinto ezinje ngokuxhathisa ubushushu, ukunganyangeki kwe-corrosion, kunye namandla oomatshini nawo kufuneka aqwalaselwe. Emva kokukhetha izinto ezingasetyenziswanga, ziyalungiswa. Ngokuqhelekileyo, i-mixer isetyenziselwa ukudibanisa ngokulinganayo i-resin yeplastiki kunye nezongezelelo, ilandelwa ngokomisa ukuqinisekisa ukomisa okuchanekileyo kunye nomlinganiselo wezinto eziluhlaza.
Extrusion
I-Extrusion yinkqubo ephambili yokwenziwa kwemibhobho yeplastiki. Ngethuba lokukhupha, izinto eziluhlaza ezomileyo zifakwe kwi-extruder ye-plasticization kunye ne-extrusion. Ngokucinezela, ukuxova, kunye nokuzolula, imathiriyeli ekrwada ikhutshelwa kumbhobho weplastiki ongenanto kunye nobungqingqwa obufunwayo kunye noburhabaxa. Oku ke kuxhomekeke kumanyathelo alandelayo okubunjwa kunye nokusika.
Ukubunjwa kunye nokuSika
Ukubunjwa kwenziwa ukufezekisa imilo efunekayo. Umatshini wokubumba ophakathi -nobubanzi obuqhelekileyo usetyenziswa ukubumba umbhobho weplastiki. Ukusika kwenziwa ukusika umbhobho owenziwe ngobude bokupakisha kunye nokusetyenziswa. Umatshini wokusika unokusebenza ngokuzenzekelayo okanye ngesandla, kuxhomekeke kwisicelo.
Ukupholisa kunye noHlolo lweMveliso
Ngethuba lenkqubo yokwenziwa kombhobho, umbhobho okhutshiweyo kufuneka upholile ukukhusela ukuguqulwa kunye nokungalingani kwesakhiwo sangaphakathi. Ukuhlolwa kwemveliso kuye kwenziwa ukuqinisekisa ukuba inkangeleko yayo, umgangatho, kunye neempawu zomzimba ziyahlangabezana nemigangatho, evumela uhlengahlengiso olungexesha kwinkqubo yokuvelisa.
Ukupakishwa kunye noGcino
Emva kokuveliswa, iipayipi zeplastiki zipakishwa ngokweenkcukacha kunye neemfuno zomgangatho. Ezi ngokuqhelekileyo zipakishwe kwipakethe ene-hexagonal okanye ukupakishwa kwe-reel. Emva kokupakisha, kufuneka zigcinwe kude nokufuma kunye nelanga elithe ngqo.
