Yam Uas Yuav Tsum Tau Them Rau Thaum Tsim Ntoo Grain PVC Floor Membrane

Cov hauv qab no yuav tsum tau hais tshwj xeeb:
Ua ntej, lub zog ntawm lub hauv paus nto. Yog hais tias lub zog ntawm lub hauv paus nto tsis tau raws li qhov yuav tsum tau los yog tsawg dhau lawm, cov epoxy resin txheej yuav rub sib nrug ntawm lub mortar nto tom qab kho, ua rau tev tawm. Koj tuaj yeem siv cov txhuam hniav los txhuam rau ntawm qhov chaw, lossis siv lub rebound tester los ntsuam xyuas lub hauv paus pob zeb kom muaj zog pob zeb, los yog siv ib tug me me rauj ntaus lub hauv paus nto los txiav txim, los yog koj muaj peev xwm ua ib tug bonding zog xeem (xws li ntau dua. tshaj 1MPa) ntawm qhov chaw;
Qhov thib ob, lub dryness ntawm lub hauv paus nto. Vim tias cov txheej txheem pob zeb thiab mortar leveling muaj ntau cov dej noo, nws yuav tsum tau qhuav kom txog rau thaum cov txheej txheem hauv pem teb yog siv. Nyob rau ntawm qhov chaw, koj tuaj yeem txiav txim siab seb qhov saum npoo puas yog xim dawb lossis ntsuas cov dej noo raws li lub sijhawm txij nkawm tom qab kev tsim kho hauv paus (nws yuav tsum tau ua raws li lub hauv paus tau kho nrog cov dej noo-pov thawj thiab cov txheej txheem dej tsis zoo);
Qhov thib peb, "flatness", uas yog, tsis muaj qhov tsis sib xws lossis qhov tsis sib xws ntawm lub hauv paus nto, thiab txheej txheej thiab mortar yog tiaj tus. Piv nrog rau cov thinner, lub flatness ntawm lub hauv paus nto yuav ncaj qha cuam tshuam rau tag nrho cov saum npoo zoo ntawm txheej. Nyob rau ntawm qhov chaw, ib tug 2-meter kav yuav txuas mus rau lub hauv paus nto kom pom tias qhov sib txawv nyob rau hauv 5 hli raws li ib txoj kev los ntsuas qhov flatness ntawm lub hauv paus nto. Rau tus kheej-leveling txheej nrog cov kev xav tau siab dua, hauv av yuav tsum sim ua kom qhov sib txawv ntawm 2-meter tus kav hauv 3 hli. Thaum lub sij hawm kev tsim kho, ib tug neeg kho tshuab grinder yuav siv tau rau ntxiv hauv zos "leveling";
Plaub, qhov smoothness ntawm lub hauv paus nto. Smoothness txhais tau hais tias lub hauv paus nto yog du heev nrog ib tug hlau trowel, thiab tsis muaj qhov ntxhib saum npoo, uas yuav cuam tshuam rau adhesion ntawm cov khoom siv hauv zaj duab xis thiab lub hauv paus. Yog hais tias lub hauv paus nto yog ntxhib tshwj xeeb, lub hauv paus lub zog yuav tsis txaus thiab cov khoom siv ntau yuav raug noj. Yog li ntawd, qhov tsim nyog roughness yog qhov tseem ceeb rau qhov kawg ntawm cov txheej hauv pem teb. On-site lub teeb sandblasting (steev) cov cav tov feem ntau yog siv rau kev kho deg thiab tshem tawm plua plav.
Cov cuab yeej siv tshuaj pleev xim tsis tuaj yeem tsis quav ntsej. Cov cuab yeej tseem ceeb muaj xws li: grinder, sandblaster, muaj hluav taws xob nqus tsev vacuum, portable electric polisher, rauj, chisel, portable hluav taws xob tov khoom (rau kev sib xyaw cov khoom tseem ceeb thiab tus neeg saib xyuas); lwm yam cuab yeej thiab cov ntaub ntawv muaj xws li: hluav taws xob digital scale (ntau tshaj 20kg), teeb pom kev zoo, thaiv lub rooj tsavxwm, kaum spatula (25cm, 30cm, 36cm), spike khau, defoaming roller lossis defoaming koob, xim txhuam, cov menyuam, serrated scraper, roj hmab scraper, tiv thaiv daim kab xev, ceeb toom board, pem teb siv quav ciab (rau kev tiv thaiv), thiab lwm yam.
Ua ntej, kev ntxuav yog ntxuav lub hauv paus saum npoo ua ntej kev tsim kho kom qhov chaw ua hauj lwm raug pom tag nrho;
Qhov thib ob, lub hauv paus kev tshawb nrhiav qhov xwm txheej ntawm lub hauv paus yog ua kom tiav thiab kev soj ntsuam kom ntxaws ntawm qhov chaw ua haujlwm los ntawm cov cuab yeej tshawb nrhiav ntawm qhov chaw, thiab ua cov ntaub ntawv ntxaws. Kev tsim kho hauv av yog ib txoj haujlwm zais cia, yog li lub hauv paus saum npoo av yuav tsum tau tshawb xyuas kom meej thiab sau tag nrho (tuaj yeem tawg mus rau hauv ntau daim duab), thiab qhov loj ntawm lub hauv paus saum npoo yuav tsum tau muab cais tawm ntawm daim duab (qhov tseeb rau centimeters);
Thib peb, kev kho mob ntawm cov ntawv txuas rau ntawm lub hauv paus nto yog feem ntau sab laug ntawm lub hauv paus nto. Cement hmoov av thaum lub sij hawm tsim kho, tshwj xeeb tshaj yog cov tshiab tsim nto muaj ntab slurry (cement dawb alkaline crystals). Cov ntawv txuas no yuav tsum tau muab tshem tawm nrog cov cuab yeej hluav taws xob lossis chisels ua ntej txheej txheej. Cov txheej txheem ntau dua yog lub teeb sandblasting. Lub mortar adhered rau lub hauv paus nto yog tshem tawm. Cov chips, av, cement ua npuas ncauj thiab roj stains yuav tsum tau muab tshem tawm kom huv si, tshwj xeeb tshaj yog cov roj stains yuav tsum tau ntxuav nrog xab npum thiab tom qab ntawd ntxuav nrog dej huv thiab qhuav tag;
Plaub, sib tsoo thiab nqus. Rau lub hauv paus qub nto nrog qhov tsis txaus siab flatness, txoj kev sib xyaw hauv zos thiab kev sib tsoo tag nrho yuav tsum tau siv rau kev sib tsoo thiab nqus;
Thib tsib, kev kho mob ntawm lub hauv paus defects (peeling, tawg, khoob). Peeling yog lub xeev qhov chaw sib txuas ntawm pob zeb thiab mortar yog tev tawm thiab tsis zoo txuas (yog tias tag nrho cov khoom sib txuas tau tev tawm, lub mortar yuav tsum tau muab tshem tawm tag thiab rov siv dua. Yog tias tsuas yog ib feem ntawm nws tau tev tawm, Nws tuaj yeem kho tau los ntawm resin grouting). Kev tawg yog feem ntau tshwm sim los ntawm tev. Thaum kho, siv lub tshuab txiav hluav taws xob txiav lub qhov U-shaped nrog qhov dav ntawm li 1 decimeter raws qhov tawg. Qhov zawj yog sau nrog resin mortar. Qhov sib txawv yog lub xeev ntawm ib feem ntawm lub hauv paus nto yog concave (txoj kev kho yog nqus thiab cheb cov plua plav thiab lwm yam av, thiab smooth nws nrog resin kua nplaum):
Thib rau, kev tiv thaiv saum npoo yog qhov tseem ceeb los tiv thaiv cov ntug ntawm kev tsim kho los ntawm kev stained thiab tuav ib txoj kab ncaj nraim (lossis txoj kab ciam teb nrog rau qhov tsis muaj coated). Daim kab xev tiv thaiv saum npoo yuav tsum tau pasted. Cov txheej txheem no yuav tsum ua kom zoo zoo ua ntej kev tsim kho ntawm primer, nruab nrab-coat thiab topcoat. Cov khoom xyaw tseem ceeb ntawm cov primer hauv qab thiab tus neeg sawv cev kho yog sib xyaw ua ke thiab sib xyaw ua ke nrog lub tshuab hluav taws xob sib txuas. Muab cov primer sib xyaw rau hauv av ntawm lub hauv paus huv si, thiab siv cov roj hmab scraper los yog cov menyuam kom sib npaug ntawm cov primer kom nkag mus rau hauv lub hauv paus. Tus nqi ntawm daim ntawv thov feem ntau yog 0.15 ~ 0.2 kg ib square meter (zoo heev puag tsuas xav tau 0.1 kg). Lub sijhawm kho primer feem ntau yog 12 teev tom qab lub xeev kho tau raug lees paub rau cov txheej txheem tom ntej. Cov txheej hauv nruab nrab yog txheej nplaum los yog txheej txheej rau kev ua haujlwm ntxiv ntawm lub hauv paus nto uas tsis sib xws los yog ib feem ntawm qhov tsis zoo. Nws yuav tsum tau npaj raws li qhov tseeb ntawm qhov chaw (feem ntau txiav txim siab los ntawm kev tsim kho tom qab kev soj ntsuam ntawm qhov chaw). Rau lub hauv paus terrazzo, tsuas yog txheej mastic tuaj yeem ua yam tsis muaj mortar txheej. Cov txheej nruab nrab yuav tsum tau kho ntau tshaj 24 teev nyob rau lub caij ntuj sov thiab ntev dua rau lub caij ntuj no. Tom qab nws tau kho tas lawm, nws yuav tsum tau polished thiab plua plav. Cov khoom tseem ceeb thiab tus neeg sawv cev kho ntawm cov txheej txheej saum npoo yog sib xyaw ua ke thiab sib xyaw ua ke nrog lub tshuab hluav taws xob sib txuas. Cov kuab tshuaj-raws li txheej txheej tuaj yeem siv nrog cov menyuam los yog scraper; cov kuab tshuaj tsis muaj tus kheej-leveling txheej tuaj yeem siv los ntawm troweling. Kev ua haujlwm tshwj xeeb yog: ncuav cov khoom sib xyaw ntawm nws tus kheej rau hauv av, ua tib zoo txhuam nws nrog serrated scraper (yog tias muaj kev tso cai, hnav khau khiab los kho qhov tsis xws luag), thiab tom qab ntawd siv lub tshuab ua npuas ncauj kom defoam. Vim tias lub sijhawm ua haujlwm zoo ntawm cov khoom siv yog li 20 mus rau 60 feeb, thiab daim ntawv thov yog kev ua haujlwm tas mus li, nws yuav tsum tau ua kom sai li sai tau thaum ua kom ntseeg tau qhov zoo ntawm scraping. Tsis muaj leej twg raug tso cai nkag mus rau qhov chaw tsim kho hauv 24 teev tom qab siv cov txheej txheem saum npoo. Tom qab paub meej tias lub xeev hardening thiab seb nws puas ua tau raws li lwm yam kev tswj xyuas zoo, siv cov txheej txheem kho kom zoo los tiv thaiv cov txheej txheej, thiab txhuam nws nrog lub tshuab polishing tom qab ziab (los ntawm tus neeg siv thaum siv nws.)
Ua ntej, npaj cov cuab yeej siv: tus pas ntsuas, rab riam siv hluav taws xob, scraper, vuam phom, nylon roller. Txheeb xyuas qhov chaw tsim kho: xyuas kom cov av huv si, tsis muaj roj, plua plav, thiab xuab zeb. Ua ntej kev tsim kho, ntsuas qhov loj ntawm qhov chaw thiab qhov flatness ntawm av. Siv tus pas ntsuas {{0}}meter los ntsuas, thiab qhov yuam kev yuav tsum tsis pub tshaj 1 hli. Yog tias qhov chaw tsim kho qhov kub thiab txias qis dua xoom, chav tsev yuav tsum tau muab cua sov kom zoo. Ua ntej kev tsim kho, cov yob hauv pem teb yuav tsum tau nthuav tawm thiab muab tso rau ntawm qhov chaw tiaj tus. Tom qab nws rov qab mus rau flatness, txiav qhov sib thooj loj raws li qhov chaw ntau. Cov kua nplaum sib txuam: Ua ntej kev tsim kho, xyuas seb cov kua nplaum puas dhau lub txee lub neej. Yuav tsum tsis muaj pob los yog nag lossis daus. Cov kua nplaum yuav tsum tau nplawm tusyees ua ntej siv. Cov kua nplaum yuav tsum yog nplaim hluav taws, tsis muaj tshuaj lom lossis tsis muaj tshuaj lom, thiab tsis muaj ntxhiab tsw ntxhiab. Cov kauj ruam ntawm kev tsim kho: Tom qab cov av tau kho thiab ua tau raws li cov qauv, tos kom cov theem kom qhuav kom zoo ua ntej mus rau cov txheej txheem tom ntej. Tom qab ua tiav qib tiav thiab kev tshuaj ntsuam xyuas tau tsim nyog, cov kua nplaum tom qab kuaj xyuas yog sib npaug rau hauv av nrog serrated scraper (li 0.3-0.5 kg / m2). Kev tsim kho ntawm cov khoom siv coiled yuav tsum tau ua nyob rau hauv ob kauj ruam: ua ntej, nteg lub coiled pem teb tiaj tus rau hauv av, ces dov li ib nrab ntawm lub hauv pem teb, thiab sib npaug zos cov kua nplaum rau hauv av ntawm lub dov pem teb. Tos kom txog thaum cov kua nplaum uas muaj nyob rau hauv cov kua nplaum uas siv rau hauv av evaporates thiab tsim viscosity, thiab tom qab ntawd muab tshuaj txhuam. Thaum pasting, thawb hauv pem teb nyob rau hauv tib txoj kev nrog koj txhais tes, thiab tsis txhob cia cua nyob rau hauv pem teb thiab kua nplaum. (Lub sij hawm evaporation ntawm cov kua nplaum hloov raws li qhov ntsuas kub ntawm kev tsim kho. Piv txwv li, ntawm qhov kub ib txwm ntawm 20 degrees Celsius, lub sij hawm evaporation ntawm cov kua nplaum yog 30 feeb. Cov kua nplaum hloov los ntawm cov mis dawb mus rau translucent. Kov hauv av nrog koj. ob txhais tes yuav tsim muaj zog viscosity Tsuas yog tom qab ntawd nws tuaj yeem muab tso rau, kom paub tseeb tias yuav tsis muaj npuas nyob rau yav tom ntej). 4. Siv tib txoj kev los paste rau lwm ib nrab. Nws yog qhov zoo tshaj plaws los siv cov nylon roller rau dov, kom cov kua nplaum thiab hauv pem teb tuaj yeem ua kom nruj dua ua ke. Tom qab ntxuav hauv av, siv rab phom vuam los txuas cov seams ntawm cov plag tsev.
Vuam txheej txheem: Ntxuav qhov khoob ntawm cov plag tsev. (xws li cov kua nplaum thiab cov roj stains) Txiav cov vuam hlau raws li qhov khoob hauv pem teb. Siv rab riam siv hluav taws xob los yog rab riam daim duab peb sab rau qhov los yog roughen ob sab ntawm qhov sib txawv yuav tsum tau welded (tsuas yog kom yaj cov vuam hlau smoothly rau hauv qhov sib txawv ntawm hauv pem teb). Kho qhov kub ntawm rab phom vuam, yaj cov vuam hlau nyob rau hauv qhov sib txawv ntawm hauv pem teb, thiab ua ntej siv rab riam los thawb nws nyob rau hauv tib txoj kev raws lub dav hlau hauv pem teb rau trimming. Tom qab ntawd, thaum qhov sib koom ua ke txias tag, siv rab riam siv hluav taws xob los ua qhov thib ob trimming kom ntseeg tau tias lub vuam pas nrig yog ntws nrog cov khoom hauv pem teb. Txiav cov vuam hlau uas tshaj lub dav hlau hauv pem teb. Lub kaum ntse ntse: Siv rab phom welding kom mos hauv pem teb ntawm lub ces kaum thiab ces curl nws. (Lub curling yog rau nruab lub concave round skirting nrog ib tug welded ob leeg) Ceeb toom: Tsis txhob siv dej ntau los ntxuav hauv pem teb nyob rau hauv 10 hnub tom qab kev tsim kho tiav, vim hais tias nws yuav siv sij hawm txog 10 hnub rau cov kua nplaum kom tiav. Yog tias koj siv dej ntau los ntxuav hauv pem teb nyob rau lub sijhawm no, cov dej yuav nkag los ntawm qhov sib txawv thiab rhuav tshem lub zog ntawm cov kua nplaum (tshwj tsis yog cov welded coil pem teb). Tom qab siv cov kua nplaum, nws yuav tsum muab tso rau hauv 3-6 teev.
