Lub hom phiaj tseem ceeb, uas yog sim ua kom tiav thaum pleev xim yas - muab cov khoom siv ntawm kev sib haum xeeb hauv chav tsev lossis lub tsev. Niaj hnub no, ntau tshaj 2 txhiab tus xim tau tsim, uas yuav pab tau muaj qhov kev xav no. Ib txoj haujlwm tseem ua - kom tau pleev xim kom zoo rau PVC profile.
Xim rau PVC
Hmoov tsis zoo, yas kuj yellows los ntawm lub sijhawm nyob rau lub sijhawm hauv qab ntawm lub hnub ci ntawm lub hnub, yog li poob nws thawj lub ntsej muag. Kuj "rhuav tshem" thiab nws cov yam ntxwv ntawm lub cev. Yog li, daim duab ntawm daim profile yuav pab tiv thaiv nws cov npoo ntawm cov kev cuam tshuam zoo li cas.
Npaj ntawm nto rau staining
Thov kom muab koj tus kheej
Painting ntawm cov yas profile los ntawm cov pleev xim acrylic ntawm cov dej hauv dej muaj qhov zoo, ntawm koj tuaj yeem faib:
- Npaj npaj ua haujlwm yog sai npaum;
- Cov nplaim taws ziab sai sai;
- Rau 8-10 teev, ua tiav dials lub zog ntawm qhov kub ntawm tsuas yog 20th;
- Xim tuaj yeem nqa tawm ob qho tib si tswj hwm thiab tsis siv neeg tsis tuaj yeem siv cov pa roj;
- Xim muaj cov nta loj zoo nkauj (qog ntawm cov ntoo, hlaws, nws yog xim hlau, thiab lwm yam).
Ib qho tseem ceeb ua ntej thov cov xim pleev xim rau ntawm cov khoom yog nws npaj ua ntej.
Ua ntej tshaj plaws, koj yuav tsum nco ntsoov tias tsis muaj av nyob rau saum npoo av, silicone seem lossis kev sib tw ua npuas dej thiab lwm yam khib nyiab, uas yog ib qho thaiv cov khib nyiab, uas yog cov nyom ntawm cov yas adhesion nrog cov xim tsev yas.
Txhawm rau npaj kev npaj zoo, koj tuaj yeem ua raws li cov lus qhia hauv qab no:
- Nrog kev pab ntawm daim ntaub ntswg los yog cua compressed, tshem tawm cov crumb thiab khib nyiab los ntawm cov khoom ntawm cov khoom;
- Kuv yog impregnate nrog cov tshuaj ntxuav tshwj xeeb uas tau ua tiav rau polystyrene;
- Tshem tawm cov rog thiab lwm lub tshuab sib xyaw ntawm cov nplaim, yog li tshem tawm cov hluav taws xob zoo li qub;
- Muab saum npoo rau 10-15 feeb, kom cov cua huv huv si evaporated.
Ua raws li cov lus qhia ntawm cov kws tshaj lij tshwj xeeb, nws yog qhov zoo dua los yuav cov kws kho mob tshwj xeeb rau PVC, uas, thaum ua ntawv thov cov nplaum ntawm cov ntaub ntawv.
Lwm txoj hauv kev los nce adhesion kuj tseem muaj lub npe - yas sib tsoo thiab nws cov khoom lag luam txuas ntxiv. Tab sis cov txheej txheem no yog qhov nyuaj dua thiab yuav tsum tau tus tswv ntawm qee yam kev txawj ntse thiab kev paub.

Ua ntej tshaj plaws, nws yuav tsum tau sau tseg tias yog tias koj cov phiaj xwm tsis suav nrog sib tsoo thiab yuav tsum tau yuav tsuas yog cov xim hlau, uas yog tsim tshwj xeeb rau pvc qauv.
Cov khoom lag luam nrov tshaj plaws ntawm cov khoom siv rau cov khoom yas yog Rhenocoll cov cim lag luam, nws cov yam ntxwv kev paub yog qhia hauv qab rooj.
| Cov seem ntawm qhov teeb meem qhuav | 40-45% los ntawm qhov hnyav |
| Ceev | 1,05-1.18 KG / L |
| Viscosity | 40-80 seconds |
| Kev noj | 80-120 ml / m2 |
| Qib ntawm Brilliance | 30-60 Cu |
| Diluent | Ywg dej |
| Kev Nyab Xeeb Chav | Tsis txaus ntshai |
| Kev Tiv Thaiv Tsis Qhuav | Txog li 160 microns |
Txhawm rau xaiv cov khoom siv tau tshaj plaws rau cov xim, koj yuav tsum tau:
- Xaiv ib qho ntxoov ntxoo kom haum los ntawm cov ntawv sau npe;
- Xam tau uas nyob rau hauv uas yuav tsum muaj peev xwm ua kom muaj kev ntseeg kev ntseeg ntawm cov nqi ntawm cov ntaub ntawv yav tom ntej;
- Khiav xim ua ntej mus txog qhov uas xav tau xim tsis tau ua ntej dua 1 teev ua ntej ua haujlwm.
Thov nco ntsoov tias ua ntej ua cov xim ntawm cov chaw, cov xim yog cov xim muaj zog zoo dua los ntawm cov sieve me me.
Subtleties Thaum Painting Surfaces
Xaiv cov xim rau PVC
Pleev xim yas zoo dua ua ib txheej ntawm chav tsev kub. Pre-Thov Cov Lus Cog Tseg Tam Sim No Ntawm No Tsis Xav Tau.
Yog tias koj muaj peev xwm ua haujlwm pancverizer, yog li cov txheej yuav ua tau zoo dua. Tsis tas li cov xim pleev xim thiab cov khoom siv vanish tuaj yeem siv siv cov txhuam txhuam lossis cov menyuam.
Cov ntaub ntawv qhuav rau 8-10 hom xuaj moos, nws tag nrho yog nyob ntawm qhov ntsuas kub. Tab sis nws muaj peev xwm siv cov xim nplaum yas tsuas yog tom qab 3 hnub. Yog tias koj xav tau, txheej yuav tuaj yeem rov ua dua, tab sis tsuas yog tom qab ziab ntawm cov txheej txheej thawj.
Nws tseem tsim nyog them sai sai rau qhov tseeb tias hauv txhua chav muaj ntau yam uas tuaj yeem ua hluav taws lossis raug kev txom nyem thaum hluav taws. Txhawm rau kom tsis txhob muaj qhov xwm txheej zoo li no, nws yog qhov zoo dua los yuav cov xim hluav taws retardant xim, uas yog diluent ntawm uas yog dog dig ntawm cov dej.

Thov Pvc ib leeg
PVC Cov Khoom Siv Xim Dries ntawm qhov ntsuas kub uas tau tshaj qhov pib ntawm 40 ° C. Canvas yuav tsum tau nteg nyob rau hauv ib tug rhuab ziab hauv 5-10 feeb. Tom qab pleev xim.
Yog tias cov av noo huab cua yog 65% thiab qhov kub ntawm 50 ° C, cov duab ntub (nrog lub micrond ntawm 80-120 microns) yuav qhuav ib ncig ntawm 180 feeb. Nws tsis tsim nyog los paub txog theem ntawm cov nplaum, muaj sijhawm, thiab ua tiav polymerization tsuas yog tom qab 5-7 hnub.
Nco ntsoov tias cov khoom lag luam yuav nce vim yog:
- ib txheej tuab tuab;
- txo qhov ntsuas kub;
- Loj kho cheeb tsam, thiab lwm yam.
Raws li nws tau pom meej meej los ntawm kev ua kom pom tseeb, cov xim ntawm cov yas tsis yog ib qho kev sim siab. Qhov loj tshaj plaws yog ua tib zoo npaj saum npoo thiab tshem tawm txhua hom pa phem. Tsuas yog tom qab ntawd nws tsim nyog xav txog cov xim thiab cov naj npawb ntawm cov khoom siv.
