Cov txheej txheem yas zaj duab xis tshuab yog ib txoj hauv kev tsim khoom tseem ceeb tshaj plaws hauv kev lag luam ntim yas. Nws yog dav siv los tsim cov tshuab ziab khaub ncaws, uas tom qab ntawd hloov mus rau ntau hom hnab yas xws li hnab khw, hnab xa ntawv, hnab ntim khoom noj, thiab hnab khib nyiab.
Kev nkag siab txog yuav ua li cas cov hnab yas tsim nyob rau hauv yob pab cov lag luam soj ntsuam cov khoom zoo, ntau lawm efficiency, thiab cov khoom muaj peev xwm. Hauv tsab xov xwm no, peb piav qhia txog cov txheej txheem ua yeeb yaj kiab tag nrho, los ntawm cov ntaub ntawv raw mus rau cov yeeb yaj kiab tiav.
Cov txheej txheem yas tshuab tshuab yog dab tsi?
Cov txheej txheem yas tshuab tshuab (tseem hu ua tshuab tshuab extrusion) yog cov txheej txheem tsim khoom siv los tsim cov yas nyias nyias los ntawm cov ntaub ntawv polyethylene xws li LDPE, HDPE, lossis LLDPE.
Hauv cov txheej txheem no:
Plastic resin pellets yog yaj.
Cov yas molten yog extruded los ntawm ib ncig tuag.
Cua yog cua tshuab mus rau hauv qhov chaw los ua ib tug npuas.
Lub npuas yog txias, flattened, thiab raug mob rau hauv yob.
Qhov kawg tshwm sim yog ib tug nruam yas zaj duab xis yob npaj rau lub hnab hloov dua siab tshiab.
Kauj ruam-los ntawm- Kauj ruam: Yuav ua li cas cov hnab yas raug tsim nyob rau hauv yob
1. Kev npaj cov khoom nyoos
Cov txheej txheem pib nrog polyethylene resin pellets. Cov ntaub ntawv uas muaj xws li:
LDPE (Low{0}}Ntev Polyethylene)
HDPE (High -Density Polyethylene)
LLDPE (Linear Low-Density Polyethylene)
Cov ntaub ntawv PE rov ua dua tshiab (yeem rau eco-kev tsim khoom zoo)
Xim masterbatch thiab additives (anti-block, slip agents, UV stabilizers) yuav raug ntxiv nyob ntawm cov khoom yuav tsum tau ua.
2. Extrusion thiab npuas tsim
Cov resin pellets yog pub rau hauv extruder, qhov twg tshav kub thiab mechanical quab yuam yaj cov khoom.
Cov yas molten hla dhau lub taub hau tuag, ua ib lub raj. Compressed cua yog nkag mus rau hauv nruab nrab ntawm lub raj, nthuav nws mus rau hauv ib tug npuas.
Qhov npuas no txiav txim siab:
Zaj duab xis dav
Thickness
