Piv txwv li, kev lag luam gluing thiab ntim kev lag luam siv ntau polyethylene thiab polypropylene lo. Cov ntsiab no feem ntau yog nyob rau hauv lub xeev ruaj khov ua ntej siv, thiab yuav tsum tau muab rhaub thiab melted thaum siv. Nws tsis zoo rau cov kua nplaum boil ncaj qha nrog cov nplaim taws qhib. Cov tuam txhab siv tshuaj feem ntau siv cov kua cua sov kom npau npau. Qhov ntsuas kub yog tswj tau, tsis muaj nplaim taws, thiab tus nqi ntawm chav yog tseem txaus.
Lub hauv paus ntsiab lus ntawm boiling kua nplaum yog kom sai yaj polyvinyl cawv ntawm ib tug ntsuas kub, thiab mus cuag ib lub sijhawm txias, thiab thaum kawg ua cov kua nplaum usable.
Nyob rau hauv cov txheej txheem ntau lawm, lub lag luam feem ntau sai sai cov ntaub ntawv xws li lub tshuab hluav taws xob thaum muaj cov khoom kub tau mus txog, thiab tom qab ntawd stirs tus khoom nyoos. Nws yuav tsum ceev nrawm thiab cov cua ntim yuav tsum tau txaus kom yaj tag cov ntaub ntawv raw.
Raws li cov lus teb, siv cov nom chav tsim hluav taws xob kom rhaub cov kua nplaum muaj peev xwm tsim cov kua hauv 2 feeb, thiab cov roj ntim sai sai, thiab cov roj ntim kuj tseem loj heev. Ib tug 1-tuj reactor tuaj yeem ua kom sov rau qhov ntsuas kub uas tau hais txog li 20 feeb, thiab cov cua kub zoo heev!
Cua sov thiab yaj cov khoom siv raw, yog tias qhov kub tsawg dhau los yog siab dhau, nws yuav cuam tshuam rau qhov zoo ntawm cov kua nplaum. Txhawm rau kom ntseeg tau tias qhov zoo ntawm cov kua nplaum yuav tsum tau ua kom sov rau cov txheej txheem cua sov, lub tshuab tso cua sov tuaj yeem tsim cov pa hluav taws xob txuas ntxiv thiab kub ruaj khov raws li cov txheej txheem.
Raws li cov chaw tsim khoom lag luam, chav hluav taws xob ncos tuaj yeem ua kom cov chav ntsuas kub nyob ntawm qhov kub thiab txias raws li cov txheej txheem zoo nkauj thiab txhim kho cov txheej txheem viscosity thiab huab cua ntawm cov kua nplaum.
Ntau cov ntaub ntawv raw hauv cov tuam txhab chemical yog cov nplaim taws thiab tawg, thiab ib qho chaw muaj kev nyab xeeb yog qhov tseem ceeb heev. Nyob rau hauv cov kua nplaum ua cov txheej txheem, cov lag luam feem ntau xaiv siv cov chav hluav taws xob cua sov chav tsim hluav taws xob. Cov khoom siv hluav taws xob cua sov chav hluav taws xob tsis tau qhib cov nplaim taws, tsis muaj kuab paug, thiab xoom emissions thaum lub sijhawm ua cua sov; Nws tseem muaj ntau yam kev nyab xeeb xws li nias, ntsuas kub, thiab kev tiv thaiv kub qhuav thiab tawg kom ntseeg tau tias cov cuab yeej muaj kev ua haujlwm.
