1, cov khoom sib txawv, PVC tube yog PVC, PPR raj yog polypropylene, PPV raj yog poly ethylene vinylene.
2 ntawm cov khoom siv raw, PVC yeeb nkab nrog ntau hom additives, cov khoom xyaw tseem ceeb ntawm PVC, thaum ntxiv lwm cov khoom xyaw los txhim kho nws cov hluav taws xob tsis ua hauj lwm, lub zog thiab cov khoom siv ntawm cov ntaub ntawv no. Kev siv lub sij hawm ntev yuav tsis muaj kev puas tsuaj rau tib neeg lub cev; raw khoom ntawm PPR raj yog ntshiab polypropylene, tsuas carbon, molecular cov ntaub ntawv hydrogen, tsis muaj teeb meem muaj teeb meem nyob ua ib ke; PPV raj siv tau ua cov ntaub ntawv luminescent.
3, nyob rau tib qho me me, PPR raj nyhav tshaj li PVC tube; PVC yeeb nkab yog siv rau cov kua ua kua, PPR yeeb nkab yog siv nyob rau hauv cov dej tsis zoo; PPV yeeb nkab yog siv rau hauv OLEDs, cov nyhuv teb chaw transistor, yees duab electrochemical cell thiab photodetector.
