EPS (Expanded Polystyrene) tshuab yog siv los tsim cov polystyrene ua npuas ncauj, feem ntau hu ua Styrofoam. Cov txheej txheem tsim khoom ntawm EPS cov cav tov muaj ob peb kauj ruam.
Kauj Ruam 1: Raw Material Preparation Thawj kauj ruam hauv EPS cov txheej txheem tsim khoom suav nrog kev npaj cov khoom siv raw. Polystyrene hlaws dai yog loaded rau hauv lub hopper, thiab ces pub rau hauv lub pre-expander. Lub pre-expander heats thiab nthuav cov hlaws dai, ua kom lawv loj tuaj txog li 50 npaug.
Kauj Ruam 2: Moulding Thaum cov hlaws tau nthuav dav, lawv npaj txhij rau molding. Cov hlaws nthuav dav yog pub rau hauv pwm, uas feem ntau yog ua los ntawm txhuas. Cov pwm yog cua sov, thiab cov hlaws dai yog txhaj rau hauv pwm siv lub tshuab nqus tsev. Raws li cov hlaws nkag rau hauv pwm, lawv pib fuse ua ke, tsim ib qho khoom thaiv ntawm EPS ua npuas ncauj.
Kauj Ruam 3: Txiav Tom qab EPS ua npuas ncauj tau molded, nws raug tshem tawm los ntawm pwm thiab txiav mus rau hauv cov duab thiab loj uas xav tau siv ib tug kub hlau cutter los yog bandsaw. Cov txheej txheem txiav tuaj yeem ua haujlwm tsis siv neeg lossis phau ntawv nyob ntawm qhov loj ntawm cov khoom thiab cov duab xav tau.
Kauj Ruam 4: Ua tiav Tom qab txiav, ua npuas dej tuaj yeem ua tiav siv ntau yam txuj ci xws li xuab zeb, txheej lossis pleev xim rau kev hloov kho ntxiv ntawm cov khoom.
Kauj Ruam 5: Ntim Thaum cov npuas tau raug txiav thiab ua tiav, nws yog npaj rau ntim thiab xa khoom.
Hauv kev xaus, cov txheej txheem tsim khoom ntawm EPS tshuab suav nrog kev npaj cov khoom siv raw, molding, txiav, xov thiab ntim cov khoom kawg.
