Kev siv cov hmoov iav, tuaj yeem ua rau kom pom tseeb ntawm cov xim

Kev siv cov hmoov iav uas tuaj yeem ua rau cov xim ci ntsa iab dua
Hmoov iav tsis yog ib yam uas ntau tus neeg tsis paub. Feem ntau nws yog siv thaum pleev xim kom ua rau lub txheej pob tshab thiab ua kom lub txheej puv dua thaum nws ua ib zaj duab xis. Nov yog kev qhia txog cov yam ntxwv ntawm hmoov iav thiab kev siv hmoov iav, kawm ntxiv txog cov ntaub ntawv siv rau kev kho kom zoo nkauj.
Cov yam ntxwv ntawm cov khoom
Hmoov iavmuaj qhov ntsuas refractive zoo, kev sib xyaw nrog xim tuaj yeem txhim kho qhov pob tshab ntawm cov xim, tshwj xeeb tshaj yog cov xim rooj tog. Ntxiv mus, txawm tias qhov ntxiv ntawm cov hmoov iav ncav cuag 20%, nws yuav tsis cuam tshuam rau kev ua haujlwm ntawm cov txheej thiab tiv taus kev khawb ntau dua. Cov hmoov iav ntxiv yuav tsis ua rau cov txheej viscosity ntau ntxiv thiab yuav tsis cuam tshuam rau daim ntawv thov. Nws kuj tseem tiv taus kev daj, huab cua kub siab, UV thiab chalking ntuj, thiab PH ruaj khov. Nws lub zog siab, yog li qhov kev sib txhuam thiab kev quav ntawm cov txheej kuj tau txhim kho.
Hmoov iav yog ua los ntawm cov khoom siv raw uas tsis ua rau ib puag ncig puas tsuaj. Los ntawm kev kho cua sov qis thiab kev sib xyaw ntau theem, qhov loj ntawm cov hmoov tau txais qhov siab tshaj plaws Z-narrow accumulation. Qhov tshwm sim no kuj ua rau kev sib tov yooj yim, vim tias nws tuaj yeem sib tov nrog lub tshuab sib tov dav dav thiab tom qab ntawd siv rau hauv cov txheej kom sib tov zoo.

Cov ntawv thov ntawm cov hmoov iav
1. Thaum siv cov hmoov iav hauv cov khoom matte, qhov sib piv ntawm cov hmoov matte tuaj yeem txo qis.
2. Qhov ntau npaum li cas yog li ntawm 3% -5%. Yuav kom paub tseeb tias nws pob tshab, qhov ntau npaum li cas ntawm cov xim ci tuaj yeem yog li ntawm 5%, thaum qhov ntau npaum li cas ntawm cov xim pleev xim tuaj yeem yog li ntawm 6% -12%.
3. Yuav kom tsis txhob muaj cov khoom me me hauv kev siv cov hmoov iav, koj tuaj yeem ntxiv 1% ntawm cov tshuaj dispersant, qhov ceev dispersing yuav tsum tsis txhob ceev dhau, txwv tsis pub xim yuav tig daj thiab dub, cuam tshuam rau cov nyhuv tha xim.
Cov teeb meem hauv kev siv ua haujlwm
1. Nws nyuaj rau tiv thaiv kom tsis txhob poob. Qhov ceev ntawmhmoov iavyog siab dua li ntawm cov xim, thiab nws yooj yim rau hauv qab ntawm cov xim tom qab diluted. Txhawm rau tiv thaiv qhov no, nws yog ib qho tsim nyog los siv kev sib xyaw ua ke ntawm kab rov tav thiab ntsug tiv thaiv kev sib sau ua ke, yog li cov xim yuav tsis sib sau ua ke rau ib lub sijhawm tom qab diluted, thiab txawm tias nws yog delaminated, nws tsuas yog siv tau los ntawm kev do.
2. Nws nyuaj rau tswj. Ntxiv cov hmoov iav rau hauv cov xim yog vim nws qhov pob tshab thiab khawb tsis kam, yog li qhov tsis muaj kev xav ntawm cov xim zaj duab xis tuaj yeem daws tau los ntawm kev ntxiv cov hmoov quav ciab rau hauv cov xim.
Los ntawm kev qhia peb txhua tus paub txog kev siv cov hmoov iav, kev siv kom raug lossis vam khom cov neeg ua haujlwm tsim kho kom xa mus. Tab sis raws li tus tswv tsev paub qhov no, koj tuaj yeem saib xyuas qhov kev nce qib ntawm qhov project kom zoo, kom tsis txhob muaj qhov tsis ua tiav ntawm cov kauj ruam no hauv kev tsim kho, ua rau cov txiaj ntsig pleev xim tsis zoo.
