Cov txheej txheem ntawm kev siv tus neeg sawv cev levelting yuav tsum tau tsom thiab ua haujlwm raws li hom txheej txheej, kev tsim kho ntawm tus neeg saib xyuas theem. Nws tau muab faib ua cov ntsiab lus hauv qab no:
1. Xaiv hom kev ua kom muaj nuj nqi theem raws li txheej txheem txheej txheej
Cov kuab tshuaj pleev xim
Primer \/ Mid-Txheej Xim: Acrylic Leveling cov neeg sawv cev (xws li nruab nrab lossis siab molecular hnyav acrylic levelecing cov neeg sawv cev) yog qhov xav tau. Thaum lub wettability ntawm lub substrate yuav tsum tau txhim kho, phosphate-hloov acrylic leveling cov neeg sawv cev tuaj yeem xaiv tau.
Sab saum toj kawg nkaus \/ pleev xim ntshiab: Siv cov neeg sawv cev ntawm cov qib siab tsawg lossis Acione Levelic cov neeg sawv cev muaj peev xwm siv tau cov pab pawg ua haujlwm tau muaj los txhim kho cov pab pawg ua haujlwm zoo nkauj thiab kos kom tsis kam; Silicone leveling cov neeg sawv cev tuaj yeem txo sagging thaum thov ntawm qhov chaw ntsug.
Hmoov Txheej
Tus neeg sawv ceveveling ua kua xav tau ua kom tiav rau hauv cov masterbatch ua ntej lossis cov hmoov pleev xim acrylic \/ silicone leveling tus neeg sawv cev kom tsis txhob muaj teeb meem shrinkage.
Cov dej pleev dej ua ke
Dej-soluble system: Siv Silicone lossis Fluorocarbon Cov Neeg Laus Tswj Xyuas, thiab siv Acrylic Leveling cov neeg sawv cev txhawm rau txhim kho cov tiaj tiaj.
Cov txheej txheem looj tes): Siv RHEEG tswj cov neeg sawv cev kom kho tau lub faving fluent, thiab acrylic leveling cov neeg sawv cev los pab txhim kho lub tiaj tus ntawm cov xim pleev xim.
2. Kev siv cov kauj ruam thiab cov ntsiab lus ua haujlwm
Ib qho ntxiv ntawm kev tswj hwm
Kev ntxiv ntau dhau yuav ua rau shrinkage thiab sagging, thaum tsis txaus yuav tsis muaj cov nyhuv tseem ceeb. Qhov tshwj xeeb ntxiv piv cov feem yuav tsum tau txiav txim siab raws li cov viscosity thiab leveling xav tau ntawm cov kev sim. Piv txwv li: Qhov kev sib ntxiv ntawm cov kev sib xyaw dav dav ntawm cov qib siab yog 2% {{% ntawm tag nrho cov nyiaj.
Dirring Street
Nws yog ib qho yuav tsum tau kom muaj kom meej kom txog thaum tus neeg sawv cev ntawm Leveling yog tusyees dispersed, thiab lub sijhawm stirringing feem ntau tsis tshaj 10 feeb. Cov txheej txheem dej ua hluav taws xob tuaj yeem siv hluav taws xob stirrers ({2}} rpm), thiab high-ceev} rpm), thiab high-ceev} rpm) pom zoo rau kev tsim kho kom loj-thaj chaw.
Txheej Txheej Txheem Yooj Yim
Kev txhuam hniav, cov menyuam txheej, txau thiab lwm cov hau kev yuav tsum tau phim cov yam ntxwv ntawm tus neeg sawv cev theem. Piv txwv li: Silicone leveling tus neeg sawv cev tuaj yeem txo cov txiv kab ntxwv tev thaum tsuag tsuag, tab sis saib xyuas yuav tsum tau them rau kev sib tw ntawm cov xim txhuas hauv cov xim xim.
III. Cov kev ceev faj
Kev sib xyaw ua tiav
Ua ntej siv, qhov sib xyaw ntawm Leveling tus neeg sawv cev thiab cov txheej yuav tsum tau kuaj kom tsis txhob shrinkage lossis taws. Piv txwv li: Silicone leveling tus neeg sawv cev yuav tsum tau hloov kho ua ntej siv los daws cov teeb meem ntawm kev ua dua tshiab.
Thiab ib puag ncig
Nyob rau hauv ib puag ncig txias, nws pom zoo kom do nrog dej sov (tsawg dua los yog sib npaug rau 40 degree) thiab ceev lub cug vias kub ntau dua lossis sib npaug rau 5 degree.
Ua kom tshuav nyiaj li cas
Nws yog ib qho tsim nyog los ua ke ntau hom kev tswj hwm theem (xws li acrylic + Silicone) lossis siv deficone) lossis siv deficone) lossis siv deficone) lossis siv deficone) lossis siv deficone) lossis siv deficone kom sib npaug, defoaming, ntub thiab lwm yam khoom.
