Cov tshuaj chlorine koom nrog cov tshuaj tiv thaiv uas txhawb kev tsim cov char thiab cuam tshuam nrog cov kev cuam tshuam cov saw hlau uas txhawb nqa cov nplaim taws, yog li tawv PVC nyiam rau tus kheej - tua yam tsis xav tau cov nplaim hluav taws kub hnyiab ntxiv. Feem ntau cov polymers xav tau cov additives kom ncav cuag qhov sib piv ntsug ntsuas. Plasticiser txo qhov kom zoo dua no, yog li cov qib hloov tau yooj yim dua li ib qho nyuaj ntawm tib lub hauv paus cob.
Puas yog qhov ntsuas zoo hais ib yam dab tsi txog kev haus luam yeeb?
Tsis muaj dab tsi hlo li. Kev tsim cov pa luam yeeb tsis yog ib feem ntawm kev lees paub hauv qhov kev sim no. Rau PVC qhov no yog qhov tseem ceeb, vim hais tias thaum cov khoom decompose nws tsim cov pa luam yeeb tuab thiab tso tawm hydrogen chloride. Qhov twg haus luam yeeb los yog tshuaj lom muaj teeb meem, qhov yuav tsum tau muaj nyob rau hauv tus qauv sib txawv, thiab qhov ntsuas kub tsis zoo yuav tsum tsis txhob nthuav tawm ua pov thawj txog nws.
Qhia peb qhov yuav tsum tau, Tsis yog qhov ntsuas
Xa peb tus qauv koj qhov project references, lub thickness thiab xim koj xav tau, thiab peb yuav paub meej tias qhov kev ntsuam xyuas siv rau qhov tshwj xeeb compound.
