Muaj ntau hom phab ntsa thiab qab nthab muab tso rau ntawm cov khoom lag luam hauv tsev. Txhua tus muaj nws tus kheej cov yam ntxwv tshwj xeeb thiab thaj tsam.
Ib qho ntawm cov neeg nyiam tshaj plaws ntawm cov khoom siv yog PVA-based putty. Hauv kab lus no, peb yuav txiav txim siab tus yam ntxwv thiab tus yam ntxwv ntawm kev sau ntawv kom ntxaws.
Khoom
Polyvinyl acetate sib tov tau yooj yim nrog dej, thiab thaum qhuav ua cov yeeb yaj kiab nrog cov khoom ua tau zoo heev. Yog li ntawd, PVA-based putty haum zoo rau feem ntau ntawm cov khoom thiab yog thoob ntiaj teb thaum ua tiav kev ua haujlwm sab hauv.
Rau qib phab ntsa, muab tso rau ntawm polyvinyl acetate emulsion tsis haum, vim qhov sib xyaw ua cov txheej nyias dhau. Yeej, qhov sib xyaw no yog siv los kho phab ntsa ua ntej pleev xim lossis pleev xim rau phab ntsa. PVA-based putty tuaj yeem siv ua txheej txheej. Kev kho saum npoo nrog cov sib xyaw ua ke yuav txawv ntawm qhov dawb thiab tus qauv txawm tias.
Cov tshuaj ziab qhuav muaj lub neej txee ntev muab tsis muaj qhov av nyob hauv chav. Kev npaj sib xyaw yuav siv tau tsis pub dhau kaum ob teev.
Koj yuav tsum khaws cov tshuaj nyob rau hauv lub thawv kaw, tom qab ntawd cov kua nplaum yuav tsis sib haum thiab ua rau tsis zoo.
Daim ntawv thov
Polyvinyl acetate-based putty yog siv rau sab hauv phab ntsa thiab qab nthab. Cov khoom siv no tuaj yeem siv tsis tau tsuas yog rau cov ntawv ntsa thiab pleev xim, tab sis kuj tseem yog cov ntaub thaiv. Cov ntaub ntawv ua tiav yog yooj yim rau nws ntau yam: tsis tas yuav yuav cov khoom sib txawv rau txhua hom saum npoo.
PVA putty haum rau yuav luag txhua yam khoom siv:
- cib;
- ntoo;
- cellular qhob;
- nthuav polystyrene;
- phab ntsa ntub dej;
- plaster;
- xim thiab varnishes;
- MDF;
- Chipboard.
Ntxiv nrog rau daim ntawv thov tus qauv, cov khoom sib tov sib xyaw tuaj yeem siv rau kev tsim khoom ntawm cov khoom zoo nkauj.
Vim nws muaj pes tsawg leeg thiab cov yam ntxwv tshwj xeeb, PVA-based putty zoo haum rau kev ua qauv thiab ua ntau yam khoom siv tes ua.
Qhov zoo thiab qhov tsis zoo
Zoo li txhua yam ntawm lwm yam putty, PVA-based sib tov muaj nws tus kheej qhov tshwj xeeb thiab qhov zoo. Cia peb hais qhov tseem ceeb ntawm cov khoom zoo li no:
- qib siab ntawm cov nplaum rau ntau qhov chaw;
- du thiab txawm nto;
- tsis muaj ntxhiab tsw ntxhiab;
- qhov tshwm sim tsawg ntawm kev tawg ntawm qhov chaw, txij li hom putty no muaj qhov zoo elasticity;
- yooj yim thov;
- kev phooj ywg zoo;
- tiv thaiv kev tsim thiab kis ntawm pwm thiab kab mob;
- xim dawb zoo meej.
Qhov tsis zoo ntawm cov khoom siv no yog, ua ntej tshaj plaws, hauv qhov txwv txwv ntawm kev thov. PVA putty tsis tuaj yeem siv:
- Rau sab nraum zoov siv.
- Rau qib phab ntsa. Txhawm rau zam kev tshem tawm thiab tawg, cov khoom siv no yuav tsum tsis txhob siv rau hauv txheej tuab.
- Rau kev kho kom zoo nkauj tiav.
- Rau ceramic thiab pobzeb.
- Hauv chav nrog cov av noo siab.
Hauv kev lag luam niaj hnub no ntawm cov ntaub ntawv tiav, koj tuaj yeem pom cov khoom sib xyaw uas tau yoog rau siv rau qee yam xwm txheej. Ntau lub chaw tsim khoom tau npaj los muab cov tshuaj pleev uas tuaj yeem siv hauv chav ntub.
Cov khoom tau txais cov khoom tiv taus ya raws vim qhov sib ntxiv ntawm cov khoom siv polymer rau cov ntsiab lus tseem ceeb ntawm cov tso quav.
Peb ua los ntawm peb tus kheej
Muaj qhov zoo thiab qhov tsis zoo hauv kev tsim tus kheej ntawm PVA-based putty. Cov txiaj ntsig suav nrog:
- Txuag … Txhua yam khoom siv xav tau los ua kom sib xyaw tau npaj tau thiab pheej yig. Ntxiv rau, koj tsis tas yuav them nyiaj ntxiv rau kev paub txog hom khoom.
- Sib tov zoo … Koj tuaj yeem hloov pauv tus kheej thiab kev faib ua feem los txhim kho cov yam ntxwv ntawm kev tso tshuaj.
Qhov tsis zoo ntawm kev sib xyaw hauv tsev yog qhov tsis muaj cov khoom tshwj xeeb uas tau ntxiv rau cov khoom tseem ceeb hauv kev tsim khoom lag luam txhawm rau txhim kho nws cov khoom. Txhawm rau ua kom PVA-based putty hauv tsev, koj yuav xav tau cov khoom siv hauv qab no:
- polyvinyl acetate emulsion;
- dej;
- txhua qhov ua kom tiav qhuav putty;
- glycerol.
PVA kua nplaum yuav tsum tau diluted hauv dej hauv qhov sib piv ib rau ib. Ntxiv glycerin thiab putty rau qhov sib tov. Cov tshuaj yog sib tov kom txog thaum tau txais creamy sib xws.
Rau kev tsim cov khoom ua tiav rau ntoo ua, av nplaum thiab PVA kua nplaum tau siv. Txoj hauv kev tsim khoom yog qhov yooj yim heev: PVA kua nplaum maj mam nchuav rau hauv cov chalk kom txog thaum cov hmoov nplej tau txais. Nws yog ib qho tseem ceeb tsis txhob hnov qab do cov tshuaj kom huv thiab zom cov pob ..
Yog tias nws yog qhov tsim nyog los ua cov av nplaum yooj yim lossis sib xyaw ua ke txhawm rau txhawm rau tawg hauv tsob ntoo, koj yuav tsum tau ntxiv cov ntoo sawdust zoo rau sib tov ntawm PVA thiab chalk.
Qhov tsis zoo ntawm cov tshuaj no yog txheej txheem ziab kom qhuav ntev.
Chaw tsim tshuaj paus
Txawm hais tias muaj pes tsawg leeg yooj yim thiab yooj yim hauv kev tsim cov khoom tiav raws PVA, nws raug nquahu kom yuav cov khoom tiav. Hauv cov xwm txheej ntawm kev tsim khoom tsim tawm, cov tshuaj tshwj xeeb tau ntxiv rau cov khoom tseem ceeb uas txhim kho qhov zoo thiab yam ntxwv ntawm cov khoom tiav.
Txhawm rau txo qhov yuav ua rau yuav cov khoom tsis zoo, nws tsim nyog xaiv los ntawm cov tuam txhab lag luam uas paub zoo, yav dhau los tau kawm txog kev tshuaj xyuas ntawm cov khoom.

Nws yog qhov xav tau los ua tus thawj hauv qhov peb txheej. Ua ntej txhua daim ntawv thov tom ntej ntawm primer, lub tsho tiv no yav dhau los yuav tsum qhuav tag.
Daim ntawv thov
Tom qab lub hauv paus rau cov putty tau npaj, koj tuaj yeem pib thov txheej txheej tiav.
Txhawm rau ua tiav txoj haujlwm, koj yuav xav tau cov cuab yeej hauv qab no:
- Hlau nqaim thiab dav muab rab riam. Siv los siv cov khoom sib tov rau phab ntsa. Qhov ntsuas yuav tsum huv si kiag li.
- Siv phom. Nws yog qhov tsim nyog rau kev sib tsoo tawg hauv qhov chaw nrog lub foob.
- Kev tsim cov yeeb yaj kiab thiab daim kab xev npog.
- Tov khoom yog kev tsim kho.
Polyvinyl acetate sai thiab tob tob rau hauv cov qauv ntawm yuav luag txhua qhov chaw, yog li nws yuav nyuaj rau tshem cov av los ntawm cov tso quav. Txhawm rau kom tsis txhob xeb chav nyob thaum ua haujlwm tiav, lub qhov rais, hauv pem teb thiab qhov rooj yuav tsum tau npog nrog zaj duab xis polyethylene. Zaj duab xis tuaj yeem kho rau ntawm qhov chaw nrog daim kab xev.
Yog tias muaj cov kab nrib pleb dav thiab tob ntawm phab ntsa, lawv yuav tsum tau kho nrog los ua kua nplaum "kua rau tes" lossis cov nplaum. Ua ntej, av thiab daim tawv nqaij raug tshem tawm ntawm qhov tawg. Tom qab tshem tawm, qhov tawg yuav tsum tau nthuav dav thiab kho nrog rab phom tsim kho.
Cov kauj ruam tom ntej yog los npaj cov tshuaj rau daim ntawv thov. Yog tias koj yuav cov tshuaj ziab qhuav, koj yuav tsum npaj cov khoom sib tov raws li cov lus qhia ntawm pob .… Yog tias koj yuav cov kua ua kua, nws raug nquahu kom ua nws nrog cov khoom sib tov ua ntej thov nws.
Putty yog siv rau saum npoo nrog cov hlau dav. Koj tuaj yeem faib cov sib tov sib xyaw ntawm cov spatula dav siv cov cuab yeej nqaim. Cov khaubncaws sab nraud povtseg yuav tsum tau siv rau ntawm phab ntsa nrog dav dav. Cov txheej tuab yuav tsum tsis pub tsawg tshaj 0.5 hli … Lub sijhawm qhuav ntawm qhov chaw tuaj yeem yog nees nkaum plaub teev. Siv cov polyurethane ntab, koj tuaj yeem txhuam cov khoom ua kom tiav kom du, ntau dua txawm tias nto.
Koj yuav kawm paub ntau ntxiv txog PVA-based putty hauv cov vis dis aus hauv qab no.
