Kev xaiv cov khoom siv raw rau cov thawv ntim khoom

Qhov zoo ntawm cov khoom yog ncaj qha ntsig txog kev xaiv cov khoom siv raw.Qhov zoo ntawm cov khoom siv raw yog nyob ntawm qhov zoo ntawm cov khoom siv raw thiab cov khoom siv raw ntxiv.Yog li ntawd, thaum tsim txhua yam khoom, peb yuav tsum tau ceev faj txog kev xaiv cov khoom siv raw.Cov chaw tsim khoom lag luam twg xav tau ntau lub hnab ntim khoom hauv kev tsim khoom, yog li dab tsi yog tus qauv ntawm cov khoom xaiv rau lub thawv ntim khoom?Peb yuav ua li cas thiaj ua tau lub thawv ntim nrog lub siab siab?Xiaobian xav qhia rau koj thiab saib.

Cov ntaub ntawv tseem ceeb rau cov hnab ntim khoom yog polypropylene, calcium carbonate thiab cov tshuaj tiv thaiv kev laus, uas yog tus cwj pwm los ntawm tus neeg saib xyuas kev laus: 3,5_ Dimethoxy-4-hydroxybenzoic acid, 3,5_ Dimethoxy-4-hydroxybenzoic acid account rau 1- 5% ntawm tag nrho qhov hnyav ntawm polypropylene.Calcium carbonate suav rau 5-10% ntawm tag nrho qhov hnyav ntawm polypropylene, thiab UV absorber yog ntxiv rau 3,5-dimethoxy-4-hydroxybenzoic acid, thiab UV absorber yog o-hydroxybenzophenone.Tom qab kev laus kev xeem, tus nqi tuav ntawm warp breaking tensile lub zog yog 70-75%, thiab ntawm weft breaking tensile zog yog 55-60%.Thaum lub hnab ntim khoom yog ua los ntawm calcium carbonate nrog 5-10% ntawm polypropylene qhov hnyav, nws muaj kev laus zoo thiab tuaj yeem siv los ua raw khoom rau lub hnab ntim khoom.Thiab nws yuav tsum raug sau tseg tias lub hnab ntim khoom yuav tsum tsis txhob raug lub hnub ntev, kom tsis txhob muaj qhov txo qis ntawm lub zog tensile ntawm polypropylene hauv cov thawv ntim khoom.

Rau cov thawv ntim khoom lag luam, tsuas yog thaum lawv tsim cov khoom ntim khoom zoo, lawv tuaj yeem txhim kho lawv txoj kev lag luam kev sib tw.Thaum ua cov thawv ntim khoom, lawv yuav tsum tsis txhob saib xyuas kev siv cov khoom siv raw thiab cov txheej txheem ua haujlwm.Tsuas yog nyob rau hauv txoj kev no lawv tuaj yeem tsim cov hnab ntim khoom tsim nyog.
