Txhawm rau thov polyurethane mus rau chav ua noj ua noj ua haus rau lub sijhawm ntev, ua raws li cov kev qhia tshwj xeeb raws cov neeg tsim khoom tshwj xeeb. Polyurethane muab cov txheej tiv thaiv uas tiv taus cov khawb, noo noo, thiab hnav txhua hnub, txuas ntxiv rau lub zog8+ xyooThaum thov kom raug.
🛠️ I. Npaj: Tseem Foundation
Tshem tawm cov khoom siv & daim ntawv lo:
Coj tawm ntawm txhua lub qhov rooj, tub rau khoom, khawm khawm, thiab kho vajtse. Daim ntawv lo rau txhua daim ntawv nrog cov neeg pleev kob daim kab xev thiab daim duab tseg kom ntseeg tau tias ua kom pom tseeb.
Defase kom meej:
Huv huv thaj chaw nrogTsp huvTxhawm rau tshem tawm chav ua noj thiab gime. Yaug kom zoo kom tsis txhob seem uas muaj kev cuam tshuam adhesion.
SAND SANDFACES:
Maj mam xuab zeb nrog150-grit sandpaperRaws ntoo nplej. Rau yav tas los cov tub rog tiav, siv80-100-gritUa ntej kom tinchure lub npoo, tom qab ntawd ua tiav nrog 150-grit rau smoothness.
Tshem cov hmoov av nrog lub tshuab nqus tsev thiabTack ntaub .
Kho Kev Kho Tsis Zoo:
Sau cov khawb / dents nrogNtoo PuttyCov. Xuab zeb du ib zaug qhuav.
🎨 Ii. Polyurethane Xaiv & Ntawv Thov
Xaiv hom yog:
| Yam tseem ceeb | Dej - raws li | Roj - raws li |
|---|---|---|
| Sijhawm kom qhuav | 2-4 teev nruab nrab ntawm lub tsho ntev | 6-10 teev nruab nrab ntawm lub tsho ntev |
| Fij daj | Nyob zoo | Yellows dhau sijhawm |
| Yam ruaj khov | Zoo | Zoo heev (siab - tsheb khiav) |
| Zoo tshaj plaws rau | Lub teeb -} xim txee | Tsaus Zoov / High -}} siv cov chaw |
Cov kauj ruam thov:
Hlob zuj zus: Zam kev tsim cov npuas. Tsis txhob co cov muaj peev xwm.
Siv cov tsho nyias nyias: Siv ahigh -} Cov Khoom Siv Hluav Taws Xob Txhuam HniavLos yog ua npuas ncauj. Ua haujlwm hauv 2x2-ft ntu, tom qab cov ntoo nplej.
Zam kev ua haujlwm: Tswj lub ntug ntub kom tiv thaiv lap cim. Overlap Strokes los ntawm 50%.
Cov naj npawb ntawm cov tsho ntev: Thov2-3 lub tsho tiv no nyiasCov. Xuab zeb maj mam nrog220-grit ntawvNruab nrab ntawm cov tsho loj tom qab ziab.
⏳ III. Kom qhuav, kho & reassembly
Kom qhuav ncua sij hawm:
Dej - raws li: Kev soj ntsuam tom qab 2-4 teev; Lub teeb siv tom qab 24 teev.
Roj - raws li: Txheeb xyuas tomqab 6-10 teev; Lub teeb siv tom qab 48 teev.
Kev Kho Mob Tag Nrho:
Dej - raws li: 21 hnub.
Roj - raws li: 30 hnub.
→ Zam kev siv hnyav lossis tso cov khoom kom txog thaum kho kom tiav.
Rov qhia dua:
Reactach Hardware thiab cov qhov rooj siv cov ntawv. Xyuas kom meej hinges yog dlhos thwj.
⚠️ IV. Kev daws teeb meem & PRO cov lus qhia
| Tsab | Lus teb |
|---|---|
| Npuas / streaks | Kev cog lus xuab zeb maj mam; Rov ua lub tsho tiv no rov qab. Siv txhuam nrog lub teeb siab |
| Qeeb Qhuav | Xyuas kom lub chav yog 70-80℃f nrog 40-60% av noo; Siv kiv cua kom dim pa |
| Yellowing (roj - raws) | Kuaj ntawm seem ntoo ua ntej; Xaiv dej - Raws li lub teeb txee |
| Hmoov av | Thov hauv plua plav -}} dawb chav; siv daim ntaub tack ua ntej txhua lub tsho tiv no |
🌿 V. Kev saib xyuas & thiav
Ntxuav: Siv xab npum me + daim ntaub mos muag. Zam kev tsis muaj abrasive lossis cov tshuaj hnyav.
Kov -} Ups: Rov thov polyurethane mus rau high - Hnav Cheeb Tsam (ze ze) txhua 1-2 xyoos.
Lub neej: Nrog kev tu kom zoo, ua tiav tas los8-10 xyoo .
