1. Muab pov tseg rau hauv cov khoom muaj nqis, ntxiv tus nqi
Cov txheej txheem pelletizing remelts, lim, thiab txiav "khoom" xws li cov khoom siv yas, zaj duab xis, thiab txiav rau hauv cov yas pellets huv si. Cov pellets no tuaj yeem muag ncaj qha rau cov chaw tsim khoom hauv qab (xws li kev txhaj tshuaj molding thiab cov tshuab tshuab tshuab), hloov cov khoom pov tseg rau hauv cov nyiaj tau los thiab nce nqi ntxiv.
2. Yooj yim cia thiab thauj mus los
Cov khib nyiab pov tseg (xws li zaj duab xis, fibers, thiab nplooj ntawv) yog qhov loj thiab nyuaj rau thauj mus rau cov tsheb thauj khoom. Tom qab pelletization, lawv ua pellets qhov loj ntawm mung taum los yog nplej nplej, uas yog ntom thiab ntws zoo. Ib tuj ntawm pellets tsuas yog ib lub hnab me me xwb qhov tsim nyog ntawm qhov chaw, txo cov nqi thauj khoom thiab cov khoom lag luam los ntawm ntau tshaj ib nrab.
3. Ua kom zoo hauv kev ua haujlwm tom ntej
Cov pellets muaj cov duab zoo ib yam, cov impurities tsawg, thiab qhov kub thiab txias. Thaum noj ncaj qha rau hauv cov tshuab txhaj tshuaj molding lossis extruders, lawv pub smoothly thiab yaj uniformly, ua rau cov khoom (xws li cov thoob khib nyiab, cov kav dej, thiab cov hnab yas) nrog cov npoo du thiab muaj zog zoo ib yam. Yog tias cov ntaub ntawv pov tseg tau ua tiav ncaj qha, nws yog qhov yooj yim rau kev tshuaj ntsuam clogging, strand breakage, thiab tsim cov pob dub.
4. Ua kom tus nqi siab tshaj plaws -Cov cuab yeej siv tau zoo
Lub hom phiaj - tshiab pelletizing kab yuav raug nqi nyob qhov twg los ntawm 100,000 mus rau ntau pua txhiab yuan, whereas ib tug siv extruder pelletizing system (muab cov ntsia hlau, chim, thiab pelletizing mechanism tsis hnyav hnyav) feem ntau raug nqi tsuas yog 30% mus rau 50% ntawm tus nqi ntawm lub tshuab tshiab, tsis tau nws cov kev ua tau zoo raws li cov kev xav tau ntawm cov nroj tsuag feem ntau {5}. Cov peev nyiaj them sai sai, ua rau nws tsim nyog rau kev pib lossis nthuav dav.
5. Hloov tau yooj yim rau ntau yam khoom siv raw
Los ntawm tsuas yog hloov cov ntxaij lim dej thiab kho cov ntsia hlau ceev thiab pelletizing ceev, ib qho kev siv pelletizing tuaj yeem ua PE, PP, ABS, PS, thiab txawm tias qee tus tsiaj. Qee lub tshuab qub yog "rugged" ntau dua li cov tshiab, tsis tshua muaj siab rau impurities, thiab muaj cov khoom siv pheej yig dua.
