Xim pleev xim Acrylic
Cov ntsiab lus tseem ceeb rau kev siv xim acrylic yog: ua kev kho kom zoo rau saum npoo, xaiv cov cuab yeej zoo, tswj qhov sib piv ntawm kev dilution, thiab ua tiav kev tsim kho hauv ib puag ncig tsim nyog.
Xim acrylic yog ib qho xim uas qhuav sai, ci ntsa iab heev, thiab tiv taus huab cua. Nws yog siv dav rau kev kho kom zoo nkauj thiab tiv thaiv ntawm cov hlau sib dua, cov qauv hlau, cov khoom siv kho tshuab, choj, cov twj paj nruag, thiab lwm yam. Txoj kev siv ncaj qha cuam tshuam rau qhov kev nplaum, kev du thiab lub neej ua haujlwm ntawm cov xim pleev xim. Yuav kom ntseeg tau tias qhov kev tsim kho zoo, nws yog ib qho tsim nyog los ua raws li cov txheej txheem ua haujlwm tus qauv.
Cov kauj ruam tsim kho thiab cov ntsiab lus tseem ceeb
- 1. Kev kho ua ntej ntawm qhov chaw
Qhov chaw pleev xim yuav tsum qhuav, huv si, tsis muaj roj av, plua plav, xeb lossis cov xim qub xoob.
Rau cov nto hlau, nws raug pom zoo kom siv cov tshuaj primer tiv thaiv xeb (xws li epoxy zinc-rich primer) ua ntej; rau cov nto pob zeb, yuav tsum siv cov tshuaj sealing primer thiab tus nqi pH yuav tsum tsis pub tshaj 105.
Yog tias cov txheej txheem qub qub lawm, nws yuav tsum tau xuab thiab ntxuav kom huv si kom txhim kho kev nplaum.
- 2. Sib tov kom huv si
Ua ntej siv, do cov xim sib tov kom huv si kom tiv thaiv cov xim kom tsis txhob los nag, uas yuav ua rau xim tsis sib npaug lossis tsis npog tag.
- 3. Kev sib xyaw thiab kev sib tov
Kho qhov viscosity raws li txoj kev tsim kho thiab dilute nws nrog cov tshuaj thinner tshwj xeeb (xws li hom X-5).
- 4. Kev Pleev Xim Rau Kev Tsim Kho
Txhuam/dov: Siv cov txhuam zoo lossis cov menyuam roj hmab uas muaj plaub ntev, thiab siv kom sib npaug zos rau tib qho kev taw qhia ntawm qhov ceev tas li kom tsis txhob muaj cov cim txhuam thiab cov npoo ntws.
Tshuaj tsuag:
Lub siab ntawm rab phom tsuag raug pom zoo kom yog 0.3–0.6 MPa;
qhov deb ntawm lub nozzle los ntawm qhov chaw yog 20-30 cm;
Qhov kev txav mus los ceev yuav tsum sib npaug zos kom tiv thaiv kev sib sau ua ke lossis kev txau tshuaj tsis raug.
Qhov tuab ntawm txhua txheej txheej yog pom zoo kom yog 30–50 μm. Tom qab nws qhuav, mus rau txheej txheej tom ntej. Lub sijhawm rov txheej dua feem ntau yog ntau dua 24 teev (ntawm 25 ℃).
- 5. Kev ziab thiab kho
Qhov kub ntawm ib puag ncig kev tsim kho yuav tsum nyob nruab nrab ntawm 5 ° C thiab 38 ° C, nrog rau cov av noo tsis pub tshaj 85%, thiab muaj cua nkag zoo.
Lub sijhawm ziab rau saum npoo yog kwv yees li 2 teev, thiab lub sijhawm ziab tag nrho yog kwv yees li 24 teev (nyob rau hauv cov xwm txheej ib txwm muaj ntawm 25 ° C).
Cov txheej txheej tsuas yog siv tau tom qab nws kho tag, thiab feem ntau nws siv sijhawm li 2 hnub thiab 10 teev.
Kev Ceev Faj thiab Kev Ntsuas Kev Nyab Xeeb
- Nyob deb ntawm cov chaw hluav taws:
Cov xim acrylic yooj yim hlawv. Tsis pub haus luam yeeb thiab hluav taws qhib hauv thaj chaw tsim kho. Tsis txhob siv hluav taws xob uas tsis muaj zog.
- Cov kev cai rau kev ua pa:
Tswj kom muaj cua nkag tau zoo kom tiv thaiv tau cov pa roj uas ua rau cov tshuaj yaj tsis sib sau ua ke, uas yuav ua rau muaj kev pheej hmoo rau kev noj qab haus huv lossis kev tawg.
- Kev tiv thaiv tus kheej:
Hnav hnab looj tes, tsom iav, daim npog ntsej muag lossis lub tshuab ua pa kom tsis txhob kov daim tawv nqaij thiab qhov muag nrog cov xim.
Cov Cai Khaws Cia: Khaws cia rau qhov chaw txias, qhuav, thiab muaj cua nkag tau zoo, deb ntawm cov chaw kub thiab tshav ntuj ncaj qha. Kaw cov thawv ntim khoom kom ruaj khov.
- Kev pov tseg ib puag ncig:
Cov kaus poom xim thiab cov kua dej pov tseg uas tso tseg yuav tsum tau muab pov tseg raws li txoj cai thiab yuav tsum tsis txhob muab pov tseg thaum twg xav tau.
Tus yuam sij rau kev siv xim acrylic kom raug yog nyob rau hauv kev tswj xyuas cov ntsiab lus kom zoo: txij li kev npaj cov khoom siv mus rau kev tswj hwm ib puag ncig, txhua kauj ruam cuam tshuam rau qhov tshwm sim kawg. Nws raug pom zoo kom ua haujlwm nruj me ntsis raws li cov lus qhia ntawm cov khoom thiab muab qhov tseem ceeb rau kev siv cov primer pom zoo kom ua tiav qhov kev nplaum zoo tshaj plaws thiab kev ruaj khov. Yog tias koj tsis paub meej txog qhov sib xws ntawm cov primer, koj tuaj yeem ua qhov kev sim me me ua ntej kom paub tseeb.
