Yam Taw Qhia:
H70 yog tsim los ntawm cov ntaub ntawv zoo, thiab nws tau dhau cov kev sim ntawm SGS.
H70 yog lub teeb daj nplaum oily kua hauv qhov kub thiab txias. Nws yuav pib freezing nyob rau hauv 0 ° C feem ntau. Viscosity yog 268 mPa.s (25 ° C) . Nws yog nyob rau hauv cov khoom sib tov ua kua (hydrocarbon compounds), ketones, esters, dej caw ntau dua thiab lwm cov organic solvents, me ntsis soluble ethanol thiab. Nws muaj kev cuam tshuam nrog cov qauv hauv PVC, tsawg volatility, mobility thiab yas rau cov yas. Nws siab thermal stability, lub teeb nyob ruaj khov thiab ua haujlwm tsis zoo rau dej thiab roj ua kom pom cov khoom siv ntawm PVC nrog kev ua tau zoo zog, huab cua ua haujlwm, tsis kub thiab hluav taws xob.

Daim ntawv thov:
H70 yog tshwj xeeb tshaj yog rau 7 0 ° C PVC phaj nyaj khoom. Tsis pub muaj cov yas phom ntxiv los yog cov stabilizers uas yuav tsum tau muaj nrog H70 nyob hauv PVC xov tooj ntawv. Cov khoom tiav tiav tag nrho cov kev qhia ntawm GBT / 8815-2008.
Kev siv: Hauv cov ntawv xov tooj cua, H70 tuaj yeem siv los ntawm 56 feem ntawm 100 tus qauv ntawm PVC thiab ua ke nrog calcium hmoov thiab roj nplua nyeem, yas rau qhov ntsuas kub yuav txo qis dua li 10 ° C.
Pob: Net weight 200kg hlau nruas los yog raws li tau thov.
