Mastering Qhov Kev ntub dej -Txoj kev embed: Cov Lus Qhia Tseem Ceeb Rau Kev Siv DRYWALL JOINT PAPER
Tso lus
Yog vim li cas 90% ntawm Seam Cracking Teeb meem pib los ntawm qhov tseem ceeb kauj ruam
Hauv kev kho phab ntsa, siv daim ntawv phab ntsa ntub dej yog qhov tseem ceeb "skeletal work" uas txuas thiab txhawb nqa. Ib txwm siv "qhuav-taping" lossis daim ntawv thov haphazard tsuas yog ntab daim kab xev rau ntawm qhov chaw, muab qhov tsis zoo ntawm kev tawg. Muaj tseeb kev craftsmanship chaw nyob ntawm lub hauv paus ntsiab lus ntawm"wet-embedding"-ib txoj kev uas sib koom ua ke ntawm mechanically thiab chemically fuses nrog cov kab xev fibers thiab phab ntsa substrate kom dhau los ua ib qho khoom loj.
Txoj kev "Wet-Embed" taping txoj kev txhais cov ntsiab lus tseem ceeb no rau hauv ib qho kev ua tau zoo, txheeb xyuas tau, plaub- txheej txheem txheej txheem. Nws yog ntau tshaj adhesion; nws yog astructural reinforcement. Mastering nws txhais tau tias koj tuaj yeem tshem tawm cov hauv paus hauv paus ntawm cov kab nrib pleb uas tshwm sim los ntawm kev sib cais ntawm cov khoom siv thiab cov hnab ris huab cua, ua kom koj kho los ntawm "vim npog-txog" mus rau "kev kho tas mus li."
Tshooj 1: Kev Npaj – Tsim lub hauv paus rau kev vam meej
Kev npaj substrate: Ib qho khoom pib taw tes
- Ntxuav thiab ruaj khov: Tshem tawm tag nrho cov khoom siv phab ntsa ntub dej, plua plav, lossis daim kab xev qub los ntawm cov seam. Rau cov phab ntsa zoo heev los yog crumbly qub, siv primer los yog bonder ua ntej kom stabilize lub substrate thiab tiv thaiv nws los ntawm nqus noo noo sai heev los ntawm cov compound.
- Groove thiab Sand: Rau cov kab nrib pleb dav, siv lub cuab yeej los txiav "V" zawj, ua rau thaj tsam ntawm qhov sib xyaw ua ke. Maj mam xuab zeb ob sab ntawm seam kom tshem tawm gloss thiab txhim kho tuav.
Npaj koj cov cuab yeej thiab cov khoom siv
- Mix Hindiaz: Sib tov sib xyaw ua ke kom du, pob -dawb, creamy sib xws. tuab heev hinders embedding; nyias nyias tsis muaj zog. Rau kev teeb tsa- hom tshuaj sib xyaw, sib tov me me.
- Txiav daim kab xev: Ua ntej- txiav daim kab xev sib txuas kom ntev me ntsis ntev (los ntawm 2-4 ntiv tes) dua li cov seams. Pre-crease daim kab xev hauv nruab nrab rau hauv cov ces kaum.
Tshooj 2: Lub Ntsiab Plaub -Txoj Kev Theem - Kev Ua Haujlwm Zoo, Ib kauj ruam los ntawm kauj ruam
Kauj Ruam 1: Siv Lub Hauv Paus Tsho - Tso "Adhesive Bed"
- Lub hom phiaj: Tsis txhob sau, tab sis kom nteg ib tug niaj hnub, nruam txaj ntawm cov nplaum rau daim kab xev.
- Kev ua: Siv rab riam uas tsim nyog (feem ntau yog 6-nti), quab yuam sib xyaw rau hauv cov seam raws nws qhov ntev. Xyuas kom lub hauv qab ntawm qhov sib txawv yog tag nrho.
- Thickness Ntsiab: CovQhov zoo tshaj plaws thickness rau lub hauv paus tsho yog hais txog 1/16 nti (1.5-2 mm). Nyias heev ua tsis tau daim ntawv cog lus; tuab heev ua rau siab shrinkage kev nyuaj siab thiab hinders embedding. Nws qhov dav yuav tsum yog me ntsis dav dua li daim kab xev.
Kauj Ruam 2: Siv daim kab xev - Qhov chaw meej
Lub sijhawm: Ua qhov no tam sim ntawd thaum lub hauv paus lub tsho yog tshiab thiab ntub. Tsis txhob cia nws tawv nqaij.
Kev ua: Muab daim kab xev rau hauv nruab nrab ntawm lub seam thiab maj mam muab tso rau ntawm qhov sib xyaw. Ua kom nws qis qis los ntawm qhov nruab nrab sab nraud nrog koj txhais tes lossis riam rov qab rau kev sib cuag thawj zaug. Qee qhov sib xyaw yuav tsum nyem tawm hauv qab.
Kauj Ruam 3: Sib Nqus thiab ntub dej -Tawm - Tus Ntsuj Plig ntawm Txoj Cai
- Cov txheej txheem: Hloov mus rau rab riam dav (8-10 nti). Tuav nws ntawm 15-30℃lub kaum sab xis rau ntawm phab ntsa, siv ruaj khov, ruaj khov siab pib los ntawmnruab nrab ntawm daim kab xev, scraping ntawm ib sab. Rov qab mus rau qhov chaw thiab khawb mus rau sab nraud.
- Kev soj ntsuam tseem ceeb: Raws li koj nias, koj yuav pomdawb compound uniformly oozing los ntawm perforations ntawm daim kab xev sib koom, tsim ib qho qauv ntawm cov xim dawb dawb los yog ib zaj duab xis nyias. Qhov no yog qhovgolden kos npe ntawm "tag nrho embedding."Nws lees tias:
1. Compound tau nkag mus rau hauv daim kab xev fibers.
2. Cov huab cua thiab cov khoom siv ntau dhau tau raug tshem tawm, tshem tawm cov npuas.
3. Lub tshuab xauv muaj zog tau tsim.
- Kev Tswj Siab: Siv lub siab txaus los nyem tawm cov huab cua thiab cov khoom siv ntau dhau, tab sis tsis txhob khawb nws tag nrho, tawm hauv daim kab xev " tshaib plab." Qhov zoo tshaj plaws tshwm sim yog ib tug nyias, translucent zaj duab xis ntawm compound sab laug rau ntawm daim kab xev.
Kauj Ruam 4: Siv lub tsho sab saum toj - Qhov tseem ceeb ntawm "Wide, nyias Feathering"
- Lub hom phiaj: Txhawm rau npog daim kab xev thiab muab nws cov npoo seamlessly rau hauv phab ntsa hauv kev sib hloov, feathered.
- Tos: Tso cai rau lub hauv paus lub tsho tiv no thiab daim kab xev rauqhuav tag(feem ntau yog 24 teev, nyob ntawm qhov xwm txheej). Nws qhuav thaum nws xav tias nyuaj, suab zoo thaum tapping, thiab tau hloov mus rau ib qho xim sib dua.
- "Wide, Nyias Feathering" Technique:
1. Siv rab riam loj 10-12 nti.
2. Siv ib txheej tshiab ntawm cov khoom sib xyaw rau ntawm thaj chaw taped, txuas zoo dhau ntawm daim kab xev (tsawg kawg 4-6 ntiv tes dav ntawm txhua sab).
3. Tuav rab riam ntawm lub kaum sab xis, siv txawm, tseem ceeb siab raukis cov compound nyias los ntawm qhov chaw tawm, tsim ib tug feathered ntug uas yuav luag tsis pom. Covlub tsho sab saum toj yuav tsum tsis txhob tuab dua 1/32 nti (tsawg dua 1 hli) ntawm nws qhov chaw.
4. Cov txheej txheem no txo cov kab ridges thiab ua tiav qhov chaw tiaj tiaj, ob qho tib si pom thiab kov.
Tshooj 3: Kev daws teeb meem thiab cov txheej txheem Advanced
Yuav ua li cas tuav sab hauv thiab sab nraud kaum?
- Sab hauv kaum: Txoj hauj lwm ua ntej -creased daim kab xev rau hauv lub ces kaum. Siv ib lub cuab yeej rau lub kaum sab xis lossis ib rab riam me los muab nws ruaj khov, ua haujlwm ntawm lub ces kaum tawm mus rau txhua phab ntsa.
- Sab nraum Cov Khaub Ncaws: Nruab ib lub hlau lossis PVC kaum hlaws ua ntej, tom qab ntawd siv txoj hauv kev "Wet-Embed" ntawm cov seams raws nws sab.
Cov cim qhia tsis ua haujlwm thiab kho
- Tsis Siv Neeg Oozing (tsis Embedded): Lub tsho hauv qab yog nyias dhau, qhuav dhau, lossis tsis txaus. Tshem tawm thiab rov ua dua.
- Daim kab xev Wrinkles lossis Slides: Lub hauv paus lub tsho yog tuab heev, dhau lawm, los yog daim kab xev tsis tau kos tam sim ntawd. Kho qhov sib xyaw ua ke thiab txhim kho kev ua haujlwm.
- Ridges raws daim kab xev Edges tom qab ziab: Lub tsho sab saum toj tsis feathered tawm thinly thiab dav txaus. Xuab zeb du tom qab ua tiav ziab thiab siv lwm lub tsho nyias nyias.
Kev cuam tshuam ntawm ib puag ncig thiab lub sijhawm
- Kub & Humidity: Tsis txhob ua haujlwm hauv qhov txias txias (<40°F / 5°C), heat, or strong drafts, as they affect drying and compound performance.
- Intercoat Qhuav: Txhua lub tsho tiv no yuav tsum tau qhuav tag ua ntej siv tom ntej. Kev ua siab ntev yog qhov yuav tsum tau ua ua ntej rau lub zog thiab tawg - kho dawb.
Los ntawm "paub" mus rau "Ua," Solidifying tus txheej txheem txheej txheem
Lub hwj chim ntawm Plaub-Kauj ruam "Wet-Embed" txoj kev dag tsis yog nyob rau hauv ib tug flashy trick, tab sis nyob rau hauv tig ib tug proventxheej txheem scientificmus rau hauv cov nqaij ntshiv. Nws hloov qhov kev xav tsis txaus ntseeg nrog qhov pom kev tswj xyuas qhov zoo ntawm "kev sib txuas oozing los ntawm perforations."
Nco ntsoov: Kev kho phab ntsa tshwj xeeb yog kev sib yuav ntawmcov ntaub ntawv txheemthiabtxheem txheej txheem. Thaum koj nruj me ntsis raws li lub suab ntawm "tso- puag / nteg-tape / embed / feather-top," thiab ua tim khawv rau lub compound los ntshav uniformly los ntawm cov perforations, koj ua ntau tshaj li patching - koj tab tom txhim kho kev ruaj ntseg nyob rau hauv lub phab ntsa. Txhim kho cov txheej txheem no, thiab koj tuav tus yuam sij tus tswv los daws qhov feem ntau ntawm cov seam -cov teeb meem tawg, pib nrog kev ua haujlwm ntawmdrywall sib koom ntawv.
