Vim li cas cov kav dej PPR thiaj li yuav tsum ntxiv cov xim tswv?

Cov xim ntawm PPR dej yeeb extrusion kab txawv. Ntxiv rau cov xim dawb thiab ntsuab uas ib txwm muaj, kuj muaj xim grey, xiav, txiv kab ntxwv, thiab lwm yam. Cov xim ntawm cov kav dej raug kho raws li lawv xav tau. Qhov laj thawj yog vim tias cov xim sib txawv ntawm "master batch" raug ntxiv thaum lub sijhawm tsim cov kav dej. Yog li xim master batch yog dab tsi thiab nws ua dab tsi?

1. Tus thawj coj yog dab tsi?

Cov khoom siv tswv yim yog cov xim lossis cov xim uas muaj ntau cov concentration, feem ntau yog cov khoom me me lossis hmoov, thiab feem ntau muaj peb ntu: tus neeg nqa khoom, xim, thiab tus pab.
Tus nqa khoom yog ib feem tseem ceeb ntawm cov xim tswv. Nws lub luag haujlwm tseem ceeb yog nqa cov xim thiab tom qab ntawd tawg thiab sib xyaw rau hauv cov yas uas xav tau hloov xim. Cov xim yog qhov tseem ceeb tshaj plaws ntawm cov xim tswv, uas ua rau cov xim tswv qhia cov xim sib txawv. Cov ntsiab lus ntxiv yog me me, uas yog los pab cov xim tawg lossis tau txais qee yam khoom tshwj xeeb, xws li antioxidant, lub teeb ruaj khov, thiab lwm yam.

2. Vim li cas ho ntxiv cov xim master batch?

Cov khoom siv raw PPR tiag tiag tsis muaj xim thiab pob tshab tsis muaj xim. Vim tias lawv tsis raug npog los ntawm lub teeb tom qab ua rau hauv cov kav dej, nws yuav yooj yim dua los tsim cov algae thiab cov kab mob hauv cov kav dej, uas yuav ua rau cov dej tsis zoo thiab ua kom cov kav dej siv tau ntev dua. Yog li ntawd, raws li cov kev cai ntawm lub teb chaws, cov xim tswv yuav tsum tau ntxiv rau hauv kev tsim cov kav dej PPR kom cov kav dej tuaj yeem tau txais cov khoom tiv thaiv lub teeb zoo.

3. Cov khoom siv ua ntej puas noj qab haus huv thiab zoo rau ib puag ncig?

Cov raj PPR uas muaj kev nyab xeeb thiab zoo rau ib puag ncig feem ntau yog ua los ntawm cov xim pleev xim rau zaub mov lossis cov xim pleev xim rau kev kho mob thiab cov ntaub ntawv nqa khoom. Cov xim pleev xim no ua tau raws li cov qauv kev noj qab haus huv thiab kev nyab xeeb thiab tsis muaj cov tshuaj lom, yog li kev xaiv cov chaw tsim khoom thiab cov neeg muag khoom txhim khu kev qha tuaj yeem ua kom muaj kev nyab xeeb ntawm cov khoom siv.

Tsis tas li ntawd xwb, thaum ua cov kav dej PPR, cov xim tswj hwm yuav tsum tau ntxiv rau hauv polypropylene raws li cov xwm txheej tsim nyog kom ntseeg tau tias muaj kev faib xim sib xws thiab tsis muaj kev tso tawm cov tshuaj lom neeg. Kev tswj xyuas zoo ntawm cov txheej txheem tsim khoom kuj tseem ceeb rau kev nyab xeeb ntawm cov khoom.

Tsis tas li ntawd xwb, rau cov kav dej PPR, lub zog zais ntawm cov pawg tswv yog qhov tseem ceeb heev, uas txiav txim siab qhov kev ua tau zoo ntawm lub teeb-shielding ntawm cov kav dej. Qhov kev ua tau zoo ntawm lub teeb-shielding kuj txhais tau tias muaj peev xwm txo qhov kev loj hlob ntawm algae thiab cov kab mob hauv cov kav dej.

Pom tau tias cov xim tswv pawg tseem ceeb heev rau PPR cov kav dej. Nws tsis yog tsuas yog siv rau kev sib txawv xim xwb, tab sis kuj txhim kho kev ua haujlwm tiv thaiv lub teeb ntawm cov kav dej thiab tiv thaiv kev loj hlob ntawm cov kab mob. Nws yog ib qho ntawm cov khoom siv raw tseem ceeb rau kev tsim cov kav dej.
