Lub Ntsiab Lus Txhais
Kev sib tov shear yog ib txoj kev sib tov uas siv qhov me me xwb. Cov zog sib txhuam, kev nias, thiab kev rhuav uas tsim los ntawm cov khoom me me, thiab ntawm cov khoom siv thiab cov hniav sib xyaw ua rau cov hmoov thiab cov agglomerates tawg ua tej daim me me.
Txoj Cai Ua Haujlwm
Thaum lub sijhawm ua haujlwm, cov txheej hmoov sib txawv txav ntawm qhov ceev sib txawv. Kev sib txhuam thiab kev txiav tshwm sim ntawm cov txheej txav ceev thiab txav qeeb, yuam kev faib thiab kho cov hmoov sib sau ua ke lossis cov hmoov nplaum. Cov khoom ntxiv me me thiab cov hmoov zoo uas nyob hauv cov agglomerates tau tawg tag nrho thoob plaws cov khoom siv hauv paus.
Cov Khoom Siv & Cov Yam Ntxwv Siv Tau
Lub tshuab no yog tsim los rau cov hmoov uas muaj roj ntau, sib xyaw me ntsis thiab yooj yim sib sau ua ke, suav nrog cov hmoov khoom noj khoom haus sib xyaw nrog cov hmoov rog microencapsulated, cov khoom sib xyaw hloov pluas noj uas muaj roj ntau, thiab cov khoom noj khoom haus uas hygroscopic me ntsis, sib sau ua ke.
Kev sib xyaw ua ke ntawm shear muab qhov tseem ceeb rau kev ua kom zoo, kev tshem tawm cov khoom sib xyaw thiab kev sib xyaw ua ke dua li kev sib xyaw ua ke sai. Nws daws cov teeb meem me me uas kev sib xyaw ua ke tsis tuaj yeem kho tau, ua rau cov khoom sib xyaw du thiab tsis muaj cov khoom sib xyaw ua ke thiab cov khoom ntxiv uas muaj nyob hauv zos.
Cov Khoom Siv Sawv Cev
Cov tshuab sib tov ob chav uas tsis muaj lub zog rub thiab cov tshuab sib tov ploughshare, uas vam khom lub zog txav muaj zog rau kev sib tov qhuav zoo.
3. Kev Sib Tov Sib Txawv: Kev Sib Tov Micro-Permeation rau Cov Qauv Me Me Uas Muaj Kev Ntsuas Siab
Lub Ntsiab Lus Txhais
Kev sib tov sib xyaw ua ke muab qhov kev sib tov meej tshaj plaws ntawm theem me me. Cov khoom siv raug pov thiab sib xyaw tas li, ua rau cov hmoov me me nkag mus rau hauv thiab sib xyaw ua ke yam tsis tau npaj tseg rau kev sib tov sib xyaw kom meej heev.
Txoj Cai Ua Haujlwm
Tag nrho lub tog raj kheej tig thiab tig rov qab, tsa thiab tawg cov khoom siv ntau zaus. Tsis tas yuav nias lossis thawb hnyav, cov hmoov me me kis tau yooj yim los ntawm lub ntiajteb txawj nqus. Cov khoom me me ntxiv nkag mus rau hauv qhov sib txawv ntawm cov hmoov khoom siv hauv paus, tshem tawm qhov sib cais ntawm cov hmoov sib dua thiab hnyav thiab kev ntsuas me me tsis sib xws.
