Siv cov khoom siv yooj yim kom tsim nyog rau nws qhov zoo
1. Cov tsos mob:Cov tsos mob yuav tsum yog dawb dawb-flowing uniform hmoov tsis muaj irritating tsw.Qhov ua tau zoo tshwm sim: xim txawv txav;impurity;tshwj xeeb yog coarse hais;tsis hnov tsw.
2. Txoj kev daws teeb meem:Siv ib qho me me ntawm redispersible polymer hmoov thiab muab tso rau hauv 5 zaug hauv dej, do ua ntej thiab tos 5 feeb kom pom.Nyob rau hauv txoj cai, qhov tsawg insoluble teeb meem precipitated rau hauv qab txheej, qhov zoo dua qhov zoo ntawm redispersible polymer hmoov.
3. Film-forming method:Siv ib tug npaum li cas ntawm redispersible latex hmoov, muab tso rau hauv 2 lub sij hawm ntawm dej, do tusyees, cia nws sawv ntsug rau 2 feeb, do dua, ua ntej ncuav cov tshuaj rau ntawm lub khob tiaj tus, ces muab lub khob nyob rau hauv ib tug ventilated ntxoov ntxoo.Tom qab ziab, saib xyuas qhov zoo nrog cov pob tshab siab zoo.
4. Cov ntsiab lus tshauv:Siv ib qho nyiaj ntawm cov kua roj hmab rov qab, ntsuas nws, muab tso rau hauv lub thawv hlau, ua kom sov li 600 ℃, kub kub li 30 feeb, txias rau hauv chav tsev kub, thiab hnyav dua.Zoo zoo rau lub teeb yuag.Kev soj ntsuam ntawm cov laj thawj rau cov hmoov tshauv siab, suav nrog cov khoom siv tsis raug thiab cov ntsiab lus tsis zoo.
5. Cov ntsiab lus noo noo:Yog vim li cas rau qhov txawv txav ntawm cov dej noo noo yog tias cov khoom tshiab yog siab, cov txheej txheem tsim khoom tsis zoo, thiab muaj cov khoom siv tsis zoo;cov khoom khaws cia yog siab thiab muaj cov khoom nqus dej.
6. pH tus nqi:tus nqi pH yog txawv txav, yog tias tsis muaj cov lus piav qhia tshwj xeeb, tej zaum yuav muaj cov txheej txheem txawv txav lossis cov khoom siv.
7. Iodine kua xim kuaj:Cov tshuaj iodine yuav tig mus rau hauv indigo thaum nws ntsib cov hmoov txhuv nplej siab, thiab cov tshuaj iodine tov xim yog siv los xyuas seb puas muaj cov hmoov polymer tov nrog cov hmoov txhuv nplej siab.
Cov saum toj no tsuas yog ib txoj hauv kev yooj yim, thiab nws tsis tuaj yeem txheeb xyuas qhov zoo thiab qhov tsis zoo, tab sis nws tuaj yeem siv rau kev txheeb xyuas ua ntej.Cov kev txwv tshwj xeeb thiab cov ntaub ntawv tseem xav tau cov cuab yeej tshaj lij thiab kev sim kom muaj kev nkag siab zoo ntawm cov khoom.
Zoo yog lub yardstick ntawm tus nqi, hom yog daim ntawv lo ntawm qhov zoo, thiab kev ua lag luam yog qhov kawg xeem tus qauv.Yog li ntawd, nws yog ib qho tsim nyog yuav tau xaiv tus kws tshaj lij thiab txhim khu kev qha cov chaw tsim khoom.
