Kev npaj ua ntej
Cov neeg ua haujlwm thiab PPE: Cov neeg ua haujlwm yuav tsum raug cob qhia thiab muaj ntawv pov thawj ua ntej pib ua haujlwm; lawv yuav tsum hnav cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) xws li cov khaub ncaws ua haujlwm, tsom iav kev nyab xeeb, thiab plua plav qhov ncauj qhov ntswg, thiab qhia luv luv txog cov haujlwm tsim khoom txhua hnub thiab cov kev xav tau zoo ua ntej pib ua haujlwm.
Kev Tshuaj Xyuas Cov Khoom Siv: Tshawb xyuas cov khoom siv (piv txwv li, pre-expanders, molding machines) rau cov khoom xoob lossis cov suab nrov txawv txav; txheeb xyuas qhov ruaj khov siab hauv chav, cua compressed, thiab cov khoom siv dej; xyuas kom cov pwm tau ruaj ntseg ntsia thiab tswj qhov kub thiab txias yog teb; thiab paub meej tias cov khawm nres thaum muaj xwm ceev yog ua haujlwm tau.
Cov ntaub ntawv pov thawj: Kev thov EPS hlaws dai ntawm qib teev; soj ntsuam rau clumping los yog impurities; xyuas kom meej tias cov khoom siv raw batch, tshuab tshuab purity, thiab pwm tso tus neeg saib xyuas kev ua tau zoo raws li cov txheej txheem; thiab xyuas kom cov ntaub ntawv khaws cia los ntawm batch nyob rau hauv qhuav, zoo-ventilated warehouse.
Txheej txheem ua ntej nthuav dav
Kev pub noj thiab cua sov: Thauj cov tshuaj ntsuam EPS hlaws dai rau hauv qhov kev nthuav dav ua ntej raws li qhov tsim nyog; qhia chav rau cua sov thaum tswj chav siab (0.15-0.25 MPa), kub (98-110 degree), thiab agitation ceev (15-25 rpm) kom cov hlaws dai maj mam nthuav.
Kub thiab Expansion Ratio Control: Kho lub sijhawm cua sov (3–8 feeb) raws li lub hom phiaj nthuav dav (25–35 zaug); tso dej ntau dhau ntawm lub sijhawm tsim nyog los tiv thaiv cov hlaws dai; thiab ua piv txwv cov hlaws ua ntej nthuav dav txhua 15 feeb los xyuas qhov ceev thiab qhov sib xws.
Tshem tawm thiab Hloov: Thaum lub hom phiaj nthuav dav mus txog, kaw lub qhov cub thiab tso cov hlaws ua ntej nthuav dav; Tom qab txias thiab qhuav, hloov lawv mus rau cov laus silo siv tshwj xeeb ventilated bins los tiv thaiv deformation los ntawm compression.
