Kev tsim cov khoom siv yas

Kev tsim cov khoom siv yas pib nrog cov khoom siv raw, uas tuaj hauv daim ntawv pellets lossis resin. Hom yas siv yog nyob ntawm qhov kev thov tshwj xeeb ntawm cov khoom siv, xws li nws lub zog, durability, thiab tsis kam mus rau cov tshuaj.

Muaj ntau cov txheej txheem tsim khoom siv los tsim cov khoom yas, suav nrog kev txhaj tshuaj molding, extrusion, tshuab moulding, thiab thermoforming. Txhua tus txheej txheem muaj nws qhov zoo thiab qhov tsis zoo, thiab kev xaiv ntawm cov txheej txheem feem ntau nyob ntawm qhov loj thiab qhov nyuaj ntawm cov khoom.

Kev txhaj tshuaj molding yog ib txoj hauv kev siv los tsim cov khoom yas. Cov txheej txheem no suav nrog cua sov cov khoom yas rau nws qhov chaw melting thiab txhaj rau hauv pwm. Thaum cov yas txias thiab tawv, cov pwm qhib, thiab cov khoom tiav raug tshem tawm.

Extrusion yog lwm cov txheej txheem siv los tsim cov khoom yas uas muaj cua sov cov khoom yas thiab yuam nws los ntawm kev tuag los tsim ib qho tshwj xeeb. Lub resulting tivthaiv yog ces txiav mus rau qhov ntev xav tau.

Tshuab moulding feem ntau yog siv los tsim cov yas hollow xws li lub raj mis los yog ntim. Cov txheej txheem no suav nrog cua sov cov khoom siv yas thiab txhaj rau hauv pwm. Tom qab ntawd cov pwm yog inflated, thiab cov yas tso cai rau txias thiab tawv.

Thermoforming yog txheej txheem siv los tsim cov khoom yas nrog cov duab tshwj xeeb, xws li ntim yas. Cov txheej txheem no suav nrog cua sov ib daim ntawv yas thiab tom qab ntawd ua rau hauv cov duab uas xav tau siv lub siab thiab pwm.

Thaum cov khoom siv yas raug tsim, lawv tuaj yeem ua haujlwm ntxiv, xws li pleev xim, txheej, lossis ua tiav, txhawm rau txhim kho lawv qhov zoo nkauj lossis kev ua haujlwm.

Hauv kev xaus, kev tsim cov khoom siv yas muaj ntau yam txheej txheem, pib nrog kev xaiv cov khoom siv raw uas tsim nyog thiab xaus nrog cov khoom tiav. Kev xaiv ntawm cov txheej txheem tsim khoom yog nyob ntawm qhov kev thov tshwj xeeb ntawm cov khoom siv, thiab txhua txoj kev muaj nws qhov zoo thiab qhov tsis zoo. Nrog rau qhov kev thov ntau ntxiv rau cov khoom siv yas, cov tuam txhab tsim khoom txuas ntxiv tsim cov txheej txheem tshiab thiab tsim tshiab los tsim cov khoom lag luam zoo thiab raug nqi.
