Kev siv cov iav hmoov, tuaj yeem ua kom cov pob tshab ntawm cov xim

Kev siv iav hmoov uas tuaj yeem ua kom cov xim pob tshab
iav hmoov tsis paub ntau tus neeg. Nws yog tsuas yog siv thaum pleev xim rau kom cov pob tshab ntawm txheej thiab ua kom lub txheej puv puv thaum nws tsim ib zaj duab xis. Ntawm no yog ib qho kev qhia txog cov yam ntxwv ntawm iav hmoov thiab kev siv iav hmoov, kawm paub ntau ntxiv txog cov ntaub ntawv siv rau kev kho kom zoo nkauj.
Cov yam ntxwv ntawm cov khoom
iav hmoovmuaj qhov zoo refractive index, sib tov nrog cov xim tuaj yeem txhim kho cov pob tshab ntawm cov xim, tshwj xeeb tshaj yog cov xim rooj tog. Ntxiv mus, txawm tias qhov ntxiv ntawm iav hmoov nce mus txog 20%, nws yuav tsis cuam tshuam qhov kev ua tau zoo ntawm cov txheej txheem thiab tiv taus kev khawb ntau dua. Cov hmoov iav ntxiv yuav tsis ua kom cov viscosity ntawm txheej thiab yuav tsis cuam tshuam rau daim ntawv thov. Nws kuj tseem tiv taus yellowing, kub huab cua, UV thiab ntuj chalking, thiab PH stability. Nws lub zog yog siab, yog li qhov kev puas tsuaj thiab folding tsis kam ntawm cov txheej kuj tseem txhim kho.
iav hmoov yog tsim los ntawm ib puag ncig tus phooj ywg raw khoom. Los ntawm kev kho qhov kub thiab txias thiab ntau theem sieving, qhov loj me ntawm cov hmoov tau txais Z-nqaum tsuj. Cov txiaj ntsig no kuj ua rau kev sib xyaw yooj yim, vim tias nws tuaj yeem tawg nrog lub hom phiaj dav dav disperser thiab tom qab ntawd siv cov txheej txheej kom sib tov zoo.

Kev siv iav hmoov
1. Thaum iav hmoov siv rau hauv matte resin, qhov kev faib ua feem ntawm matte hmoov yuav txo tau.
2. Qhov ntau npaum li cas yog li 3%-5%. Txhawm rau ua kom pom tseeb, qhov ntau npaum ntawm cov xim ci tuaj yeem nyob ib puag ncig 5%, thaum cov xim xim xim tuaj yeem nyob ib puag ncig 6% -12%.
3. Txhawm rau kom tsis txhob muaj cov khoom siv hauv cov iav hmoov, koj tuaj yeem ntxiv 1% ntawm cov dispersant, lub dispersing ceev yuav tsum tsis txhob ceev heev, txwv tsis pub cov xim yuav tig daj thiab dub, cuam tshuam rau cov nyhuv painting.
Teeb meem hauv kev siv tswv yim
1. Nws yog ib qho nyuaj los tiv thaiv kev poob dej. Qhov ntom ntawmiav hmoovyog siab tshaj ntawm cov xim, thiab nws yog ib qho yooj yim rau precipitate nyob rau hauv qab ntawm cov xim tom qab dilution. Txhawm rau tiv thaiv qhov no, nws yog ib qho tsim nyog yuav tsum tau siv kev sib xyaw ua ke ntawm kab rov tav thiab ntsug los tiv thaiv txoj cai, kom cov xim yuav tsis nyob twj ywm rau lub sijhawm tom qab dilution, thiab txawm tias nws yog delaminated, nws tuaj yeem siv tau los ntawm kev nplawm nkaus xwb.
2. Nws yog qhov nyuaj rau tswj. Ntxiv iav hmoov hauv cov xim yog tsuas yog rau nws cov pob tshab thiab khawb tsis kam, yog li qhov tsis xav ntawm cov xim zaj duab xis tuaj yeem daws tau los ntawm kev ntxiv cov hmoov av hauv cov xim.
Los ntawm kev taw qhia peb txhua tus paub txog kev siv iav hmoov, siv kom raug lossis tso siab rau 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 ua tau zoo ntawm qhov project, kom tsis txhob muaj qhov cuam tshuam ntawm cov kauj ruam no hauv kev tsim kho, ua rau cov duab tsis zoo.
