PVDC thiab ib puag ncig

Nws tsis yog PVC, tab sis PVdC muaj cov tshuaj chlorine thiab txhawb kev txhawj xeeb txog qhov kawg ntawm lub neej pov tseg los ntawm incineration qhov twg nws tsim ib qho zoo sib xws ntawm dioxins li PVC. 1.

Tsis tas li ntawd, vim li cas PVDC tsis zoo?

PVDC yog suav tias yog cov kab mob rau cov kwj deg uas tsim tau zoo (xws li PE) vim tias nws degrades ntawm qhov kub thiab txias, ua rau feem ntau ntawm cov khoom siv polymer siv tsis tau. Txawm tias me me ntawm PVDC tau tshaj tawm tias muaj kev cuam tshuam rau qhov zoo ntawm cov khoom siv rov ua dua tshiab.

Tsis tas li ntawd, qhov txawv ntawm PVC thiab PVDC yog dab tsi? Coated PVC films muaj ib tug tuab ntawm 8-10 mil; lub thickness ntawm PVDC lub tsho tiv no yog 1-2 mil. Cov txheej txheej yog siv rau ntawm ib sab thiab feem ntau yog ntsej muag ntawm cov khoom thiab cov ntaub npog. PVDC muab kev tiv thaiv zoo rau ob qho tib si oxygen thiab dej vapor thaum feem ntau lwm yam barrier polymer muab ib qho los yog lwm yam.

Hauv qhov no, PVDC txheej yog dab tsi?

PVDC ( coated ) zaj duab xis yog tsuas yog siv rau hauv ntim khoom noj, tshuaj, tshuaj pleev ib ce, thiab lwm yam perishable los yog ilv khoom kom ntev txee lub neej. Hauv kev sib piv nrog ntau cov yeeb yaj kiab, PVDC coated films muaj superior roj thiab noo noo barrier zog, thiab zoo heev tshav kub sealability.

Puas yog PVDC biodegradable?

PVDC yog ib daim ntawv ntawm cov yas uas ua rau cov khib nyiab thiab ua rau muaj kuab paug. Biodegradable ntim cov yeeb yaj kiab xws li PHBV muab cov tshuab ua haujlwm siab thaum lawv lub neej zoo li qub PVDC films thiab yog tag nrho bio- degradable tom qab kawg ntawm lub neej.
