Kev txheeb xyuas cov qauv kev cai thiab cov ntsiab lus tseem ceeb ntawm Wood Moulding Installation thiab Finishing Techniques
01 Technical Specifications thiab Installation Preparation for Wood Trim Molding
1.1 Technical Specifications
Cov ntsiab lus noo noo thiab formaldehyde emission yog cov cim tseem ceeb rau kev soj ntsuam ib puag ncig tus phooj ywg thiab ua haujlwm ntev ntawm cov ntoo trim moldings.
1.1.1 Moisture Content Requirements
Cov dej noo ntawm cov khoom ntoo trim moldings thiab ntiv tes- sib koom ua ke ntoo trim moldings yuav tsum tau tswj siab tshaj 7% ua ntej siv, thiab yuav tsum tsis txhob tshaj qhov sib npaug ntawm cov dej noo ntawm cov ntoo hauv thaj chaw uas tsim kho. Cov ntsiab lus noo noo ntawm engineered ntoo trim moldings yuav tsum ua tau raws li lub teb chaws tus qauv rau cov khoom siv board.
1.1.2 Formaldehyde Emission Requirements
Rau trim moldings ua los ntawm cov ntiv tes-cov ntoo sib koom, ntoo engineered, los yog ntoo- cov ntaub ntawv yas sib xyaw, cov formaldehyde emission yuav tsum raug kuaj thiab yuav tsum tsis pub tshaj 1.5 mg/L.
1.2 Pre-Kev Npaj Ua Ntej
Ua ntej kev tsim kho, cov ntaub ntawv thiab cov cuab yeej yuav tsum tau kuaj xyuas thiab kho cov substrate kom paub meej tias cov txheej txheem tom ntej.
Kev npaj khoom siv
Tus neeg cog lus yuav tsum npaj tag nrho cov khoom tsim nyog xws li ntoo trim moldings, adhesives, thiab fasteners ua ntej, thiab xyuas cov cuab yeej thiab cov cuab yeej. Twisted, tawg, thiab rotten qhov chaw ntawm trim moldings yuav tsum tau muab tshem tawm kom ntseeg tau tias cov moldings yog lawm. Cov ntoo xaiv yuav tsum yog cov xim sib xws, tuab, thiab qhov chaw du yam tsis muaj qhov pits lossis kev puas tsuaj los xyuas kom meej qhov zoo nkauj tag nrho.
Tom qab cov ntaub ntawv tuaj txog ntawm qhov chaw, cov txheej txheem tiav yuav tsum tau teem caij raws li xim sib txawv ntawm cov khoom siv hauv paus thiab qhov kawg. Yog hais tias cov ntoo trim thiab cov khoom siv hauv paus yog tib yam thiab cov xim tiav zoo ib yam, kev ua haujlwm tiav tuaj yeem ua tiav ib txhij nrog lub hauv paus tiav. Yog tias muaj qhov sib txawv ntawm cov khoom siv lossis xim, kev ua haujlwm tiav yuav tsum tau ua nyias nyias tom qab lub hauv paus tiav tiav.
Base Treatment: Xyuas seb lub hauv paus txheej ntawm qhov sib koom ua ke yog ruaj khov thiab seb qhov chaw tiaj tus. Yog tias lub hauv paus txheej tau pom tias xoob lossis tsis sib xws, nws yuav tsum tau ntxiv dag zog thiab kho lub sijhawm los tsim cov xwm txheej zoo rau kev ua haujlwm tiav.
02 Installation txheej txheem
2.1 Cov kauj ruam ntawm kev txhim kho: Cov ntoo trim installation txoj hauj lwm yuav tsum yog qhov tseeb, thiab cov pob qij txha yuav tsum nruj kom ntseeg tau tias tag nrho cov firmness thiab flatness kom ua tiav cov kev xav tau zoo nkauj.
Tom qab lub hauv paus kev kho mob tau txais, cov ntoo trim installation tuaj yeem pib. Kev tsim kho yuav tsum nruj me ntsis ua raws li cov qauv kos duab rau qhov chaw kom ntseeg tau tias muaj tseeb installation. Cov pob qij txha ntawm cov trim yuav tsum muaj qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. Thaum lub sij hawm tsim kho, lub firmness thiab flatness ntawm cov moldings yuav tsum tau soj ntsuam tas li kom paub meej cov ntsiab lus zoo.
2.2 Kho thiab Splicing Methods
Ntoo moldings tuaj yeem kho tau siv cov nplaum los yog nailing txoj kev. Thaum splicing, xim yuav tsum tau them rau qhov tseeb ntawm cov pob qij txha thiab kev zoo nkauj tiav.
Adhesive kho yog txoj kev nyiam los xyuas kom muaj kev sib txuas ruaj khov. Yog tias siv nailing, nws raug nquahu kom siv rab phom ntsia hlau thiab kos lub taub hau ntsia hlau rau hauv qhov zawj ntawm molding los yog ntawm sab deb ntawm qhov pom, kom ntseeg tau tias nws tsis raug.
Splicing tuaj yeem ua tiav los ntawm kev sib txuas ncaj nraim los yog kaum splicing. Rau kev sib txuas ncaj, qhov kawg ntawm cov moldings yuav tsum tau txiav ntawm 30℃lossis 45℃lub kaum sab xis, tus ntoo khaub lig- ntu yog siv nrog cov kua nplaum, thiab tom qab ntawd spliced, ua kom muaj kev sib koom ua ke. Rau kaum splicing, lub kaum sab xis 45℃yog xav tau rau qhov chaw, thiab cov saw zoo yog siv rau kev txiav (ua kom lub tiaj tiaj, burr-dawb hla-} ntu), cov kua nplaum yog siv, thiab tom qab ntawd cov moldings tau koom nrog, dua kom tsis txhob muaj qhov sib txawv lossis qhov khoob.
Tag nrho cov molding splicing pob qij txha yuav tsum tau teem nyob rau hauv lub qhov muag theem los yog nyob rau hauv ib tug inconspicuous qhov chaw los tuav lub zuag qhia tag nrho aesthetics ntawm zoo nkauj nto.
