PVC yas khoom

1. Mos PVC feem ntau muaj 30-50 feem pua ​​plasticizer. Vim nws qhov kev ntxhib los mos thiab lub zog siab; nws muaj zoo huab cua nruj thiab dej impermeability.

2. Rigid PVC yog tsim nrog tsuas yog ib qho me me ntawm cov yas yas. Nws yog tus cwj pwm los ntawm kev ntxhib los mos, siab mechanical zog thiab zoo tshuaj corrosion kuj. .

3. Polyvinyl chloride yas muaj cov cua sov tsis zoo, thiab nws lub zog muaj zog heev los ntawm qhov kub thiab txias. Lub zog ntawm -20 degree yog 80 feem pua ​​qis dua li ntawm 20 degree . Yog li ntawd, cov khoom siv zaj duab xis tsis yooj yim rau khaws cia thiab siv qhov kub thiab txias; Kev siv kub ntawm cov khoom muag tsis pub tshaj 45 degree, thiab kev siv kub ntawm cov khoom tawv tsis tshaj 60 degree, uas yuav muaj hnub nyoog thiab ua nkig thaum raug lub teeb rau lub sijhawm ntev.

4. Thaum lub sijhawm ua cov yeeb yaj kiab PVC, txhawm rau tiv thaiv thermal decomposition, nws yog ib qho tsim nyog yuav tsum tau ntxiv cov cua sov stabilizer. Txij li thaum tshav kub kub stabilizer muaj cov ntsev ntsev, thiab lwm yam, PVC yas yog tshuaj lom, yog li nws tsis tuaj yeem siv los ua cov ntim khoom noj.

5. Polyvinyl chloride plastics tiv tauj nrog cov kuab tshuaj organic thiab naphthalene thiab lwm yam tshuaj tua kab, uas yuav ua rau cov nplaum nplaum thiab yaj, thiab yooj yim nqus cov ntxhiab tsw; vim muaj zog volatility ntawm plasticizers, nws tsis haum rau khaws cia ntev heev.
