Putty hmoov poob tawm yog ib qho teeb meem zoo hauv kev tsim kho, uas yuav cuam tshuam rau cov tsos thiab kev pab cuam lub neej ntawm lub tsev. Txhawm rau tiv thaiv qhov teeb meem ntawm cov hmoov putty ntog, nws yog ib qho tsim nyog yuav tsum pib los ntawm ntau yam xws li kev xaiv cov khoom siv, kev tsim kho tshuab thiab kev tswj xyuas.
1. Xaiv cov hmoov putty zoo
Khoom zoo
Xaiv cov hmoov putty uas ua tau raws li cov qauv: Yuav cov khoom uas ua tau raws li lub teb chaws cov qauv (xws li GB / T 9779-2005 "Lub Tsev Sab Hauv Phab Ntsa Putty" thiab JG / T 157-2009 "Lub Tsev Sab Nraud Sab Nraud Putty") kom ntseeg tau tias nws lub zog sib txuas, compressive zog thiab lwm yam qhia tau tsim nyog.
Kev tshuaj xyuas cov khoom xyaw: Cov hmoov putty zoo feem ntau muaj qhov tsim nyog ntawm cov kua nplaum hmoov thiab cellulose ether, uas tuaj yeem txhim kho lub zog sib txuas thiab tawg tsis kam ntawm putty. Tsis txhob siv cov hmoov putty uas muaj cov khoom tsis zoo los yog cov hmoov pob zeb ntau dhau, uas yooj yim ua rau cov hmoov poob.
Cov neeg tsim khoom xaiv
Hom lub koob npe nrov: Xaiv cov chaw tsim khoom nrog lub koob npe zoo thiab cov lus ntawm lub qhov ncauj kom ntseeg tau tias muaj kev ruaj ntseg thiab sib xws ntawm cov hmoov putty.
Kev txhawb nqa: Qee lub tuam txhab muab kev txhawb nqa thiab kev tsim kho, uas tuaj yeem pab daws teeb meem zoo dua hauv kev tsim kho.
2. Txhim kho kev tsim kho technology
Kev kho saum npoo
Kev tu lub ntsej muag: Ua kom lub ntsej muag huv si ua ntej kev tsim kho, tsis muaj plua plav, roj thiab lwm yam kuab paug, txwv tsis pub nws yuav cuam tshuam qhov adhesion ntawm putty thiab nto.
Deg moistening: Rau qhov chaw uas muaj dej nqus dej (xws li cov phab ntsa pob zeb), lawv yuav tsum tau moistened kom zoo ua ntej kev tsim kho kom tsis txhob ntog los ntawm absorbing noo noo nyob rau hauv putty sai heev, ua rau kom adhesion txo.
Kev tsim kho tej yam kev mob
Ib puag ncig kub thiab av noo: Zam kev tsim kho ntawm qhov kub siab dhau lossis qis dhau, qhov kub zoo tshaj yog 5 ℃ ~ 35 ℃. Cov av noo ntau dhau (qhov txheeb ze av noo tshaj 85%) kuj tsis haum rau kev ziab ntawm putty, thiab kev tsim kho yuav tsum tau nqa tawm hauv huab cua tsim nyog.
Txheej tswj: Putty tsim yuav tsum tau nqa tawm nyob rau hauv cov khaubncaws sab nraud povtseg, thiab thickness ntawm txhua txheej yuav tsum tsis txhob ntau tshaj 1-2 hli. Xyuas kom meej tias txhua txheej ntawm putty yog tag nrho qhuav ua ntej txheej tom ntej yog tsim.
Txoj kev tsim kho
Do kom sib npaug: Putty hmoov yuav tsum tau tov nrog dej hauv kev faib ua feem thiab nplawm kom txog thaum tsis sib xws kom tsis txhob muaj cov khoom los yog pob. Lub sij hawm stirring feem ntau yog li 5 feeb kom paub meej fusion ntawm cov ntaub ntawv.
Smooth scraping: Putty yuav tsum tau txhuam kom sib npaug kom tsis txhob tawg thiab hmoov los ntawm qhov tsis sib xws hauv zos thickness. Siv lub zog nruab nrab thaum lub sij hawm tsim kho kom tsis txhob khawb dhau nyias lossis tuab dhau.
3. Tus tswj xyuas tsim nyog.
Qhuav lub sij hawm
Kev ziab kom tsim nyog: Tom qab kev tsim kho putty tiav, lub sij hawm ziab yuav tsum tau tswj kom tsim nyog raws li ib puag ncig kom tsis txhob ziab sai dhau los yog qeeb dhau. Nyob rau hauv ib txwm muaj xwm txheej, nws yuav siv li 48 teev kom qhuav kom qhuav, thiab lub hnub ci zog thiab cua txias yuav tsum zam lub sijhawm no.
Kev kho saum npoo
Sandpaper polishing: Tom qab cov putty qhuav lawm, siv cov ntawv xuab zeb zoo (320 mesh lossis ntau dua) los maj mam txhuam nws kom ua kom lub ntsej muag tiaj tus thiab du, thiab tsis txhob muaj zog ntau dhau los ua cov hmoov av.
Kev tsim kho tom ntej
Xim txhuam hniav: Tom qab lub putty polished, lub topcoat los yog xim yuav tsum tau siv nyob rau hauv lub sij hawm los tiv thaiv lub putty txheej. Cov xim yuav tsum sib haum nrog lub putty kom tsis txhob muaj teeb meem tom qab los ntawm cov khoom siv mismatch.
4. Tej teeb meem thiab kev kho mob
Hmoov txheej
Kev kho hauv zos: Rau cov cheeb tsam uas cov hmoov poob lawm, koj tuaj yeem rov qab siv cov putty tom qab kev sib tsoo hauv zos kom paub meej tias lub hauv paus huv si thiab siv cov kev tu kom tsim nyog.
Kev tshuaj xyuas tag nrho: Yog tias cov hmoov loj loj tshwm sim, kev tsim kho thiab lub hauv paus ntawm lub putty yuav tsum tau kuaj xyuas, thiab qhov ua rau yuav tsum tau kho tag nrho tom qab pom tau tias, thiab rov tsim kho dua yog tias tsim nyog.
Tiv thaiv cov teeb meem rov tsim dua tshiab
Kev txhim kho cov txheej txheem: Cov ntsiab lus ua rau cov teeb meem hmoov av thiab txhim kho cov txheej txheem tsim kho, xws li kho qhov sib piv ntawm putty thiab txhim kho txoj kev sib xyaw.
Kev cob qhia cov neeg ua haujlwm tsim kho: Txhim kho kev cob qhia cov neeg ua haujlwm tsim kho, txhim kho cov txheej txheem kev tsim kho thiab kev paub zoo, thiab txo cov teeb meem hmoov av los ntawm kev ua haujlwm tsis raug.
Txhawm rau tiv thaiv cov teeb meem ntawm putty hmoov los ntawm kev tsim kho, nws yog ib qho tsim nyog yuav tsum ua tib zoo xav txog ntau yam xws li kev xaiv cov khoom siv, txheej txheem kev tsim kho, kev tswj hwm ib puag ncig, thiab kev tswj xyuas. Xaiv cov hmoov putty zoo, nruj me ntsis raws li kev tsim kho, thiab ua txoj haujlwm zoo ntawm kev tswj xyuas tom ntej yog tus yuam sij kom ntseeg tau qhov zoo ntawm putty thiab kev tsim kho. Tsuas yog los ntawm kev siv zog rau kev ua tau zoo nyob rau hauv txhua qhov txuas tuaj yeem ua rau peb tsis txhob muaj teeb meem hmoov av thiab ua kom muaj kev zoo nkauj thiab ua haujlwm ntev ntawm cov tsev.
