Yuav ua li cas kom tsis txhob muaj teeb meem kev laus thaum lub sij hawm siv lub hnab tuj yog qhov tseem ceeb heev, yog li yuav ua li cas kom tsis txhob muaj teeb meem kev laus ntawm lub hnab tuj?
1. Nws yog ib qho tsim nyog yuav tsum nkag siab tag nrho cov neeg siv khoom tiv thaiv kev laus rau lub hnab ntim, xws li lub sijhawm siv, thiab lwm yam. Qee cov neeg siv khoom yuav muab lub sijhawm sim thiab qhov kawg tuav lub zog ntawm cov khoom siv dag zog nrawm, thiab qee cov neeg siv khoom yuav txawm tias cov nce UV additives. Raws li kev xav tau ntawm cov neeg siv khoom, tsim cov kev npaj rau cov khoom.
2. Npaj cov qauv tsim. Vim tias cov khoom siv rov ua dua tshiab tau dhau los lawm, cov saw hlau molecular tau tawg, cov khoom siv kho tshuab tau raug txo kom tsawg, thiab lub neej ua haujlwm tau luv luv. Txhawm rau daws qhov teeb meem kev laus ntawm lub hnab ntim, nws yog ib qho tsim nyog yuav tsum tau ua kom muaj kev tiv thaiv kev laus ntxiv raws li qee qhov kev faib ua feem. Yog tias kev siv cov khoom siv UV ntxiv yuav ua rau cov khoom tawg yooj yim rau kev daws teeb meem, kev tsim cov cuab yeej yuav nyuaj rau kev ua, thiab cov anti-aging masterbatch tuaj yeem daws qhov teeb meem no. Rau cov khoom xim, xim masterbatches nrog cov qib lightfastness sib txawv yuav tsum raug xaiv raws li cov neeg siv khoom xav tau.
3. Rau anti-aging masterbatch uas txhim kho cov nyhuv anti-aging ntawm tuj lub hnab, cov neeg siv khoom yuav tsum tshawb xyuas kom zoo. Txawm hais tias qhov nce me me, cov nyhuv tseem ceeb heev. Nws yog ib qho tsim nyog los muab cov kev cai nruj rau cov neeg siv khoom los tiv thaiv kev laus masterbatch kom lav tag nrho cov khoom zoo.
4.- Ib lub hnab loj tsis zoo muaj cov ntaub hauv qab, cov hlua khi, cov hlua khi thiab cov xov xaws, txhua yam yuav tsum ua kom tau raws li qhov xav tau ntawm kev tiv thaiv kev laus, yog tias muaj teeb meem, cov txiaj ntsig loj yuav tshwm sim, thiab ntau tus neeg siv tau txais cov kev paub zoo sib xws.
