Txhaj tshuaj molding tshuab ntsia hlau thoob ua lub luag haujlwm tseem ceeb hauv kev txhaj tshuaj molding txheej txheem ntawm PE (polyethylene) thiab PP (polypropylene) cov ntaub ntawv.Nws daim ntawv thov nyob rau hauv ob cov ntaub ntawv no muaj nyob rau hauv qab no: Melting thiab sib tov ntawm cov ntaub ntawv: Lub taub hau ntsia hlau hla dhau lub rotating ntsia hlau thiab lub cua sov cheeb tsam kom tag nrho cov cua sov thiab compress cov PE los yog PP hais kom yaj lawv mus rau hauv ib tug flowable yaj.Nyob rau tib lub sijhawm, qhov sib xyaw ua ke hauv cov ntsia hlau thoob tuaj yeem sib xyaw cov khoom sib txawv ntawm cov khoom sib txawv kom ua tau raws li qhov yuav tsum tau ua ntawm cov khoom tshwj xeeb.Siab thiab txhaj tshuaj: Nyob rau hauv qhov kev txiav txim ntawm cov ntsia hlau chim, cov khoom PE los yog PP yog txhaj rau hauv pwm kab noj hniav los tsim cov khoom zoo.Lub siab thiab txhaj tshuaj ceev ntawm lub taub hau taub hau tuaj yeem hloov kho raws li cov khoom xav tau los xyuas kom meej qhov zoo ntawm kev txhaj tshuaj molding khoom.Kev tswj qhov kub thiab txias:
Lub taub hau ntsia hlau feem ntau yog nruab nrog lub ntsuas kub tswj xyuas kom ntseeg tau tias cov khoom molten tseem nyob ntawm qhov kub thiab txias.Nyob rau tib lub sijhawm, tom qab kev txhaj tshuaj molding tiav, cov khoom yuav tsum dhau los ntawm lub tshuab ua kom txias kom ruaj khov rau cov khoom thiab tswj nws cov duab.
Kev tswj thiab saib xyuas cov txheej txheem txhaj tshuaj molding: Lub taub hau ntsia hlau feem ntau yog nruab nrog kev tswj hwm thiab kev tswj xyuas qhov ntsuas tsis zoo xws li kub, siab thiab txhaj tshuaj nrawm thiab kho lawv raws li xav tau.Qhov no ua rau cov khoom zoo sib xws thiab kev tsim khoom zoo.
Nyob rau hauv luv luv, lub hau ntsia hlau ntawm lub tshuab txhaj tshuaj molding ua lub luag haujlwm tseem ceeb hauv kev txhaj tshuaj molding txheej txheem ntawm PE thiab PP cov ntaub ntawv, kom ntseeg tau tias cov ntaub ntawv yog tag nrho melted thiab tov, thiab cov txheej txheem txhaj tshuaj molding yog tiav los tsim cov khoom zoo. txhaj tshuaj molding khoom.
