Ufa wa latex wosungunukanso (RDP)ndi chinthu chopangidwa ndi polima chomwe chimagwiritsidwa ntchito kwambiri mumakampani omanga, nthawi zambiri chimagwiritsidwa ntchito ngati chowonjezera pa putty, kupaka utoto, zomatira ndi zinthu zina. Ntchito yake yayikulu ndikuwonjezera kusinthasintha, kumatira, kukana madzi komanso mphamvu zoletsa ukalamba za chinthucho.
1. Konzani kumatirira kwa putty
Kuonjezera ufa wa latex wosungunukanso ku putty kungathandize kwambiri kumamatira pakati pa putty ndi pamwamba pa maziko (monga simenti, gypsum board, ndi zina zotero). Pambuyo poti ufa wa latex wasungunuka m'madzi, umapanga chinthu cha colloidal, chomwe chingapangitse mphamvu yolimba yolumikizana pakati pa putty ndi pamwamba pa maziko. Kumatira kowonjezereka kungathandize kwambiri mphamvu yomanga ya putty, kupewa ming'alu, kutayika ndi mavuto ena, ndikuwonjezera moyo wa putty.
2. Kuonjezera kusinthasintha ndi kukana ming'alu ya putty
Kusinthasintha kwa putty ndi chinthu chofunikira kwambiri chomwe chimakhudza kulimba kwake komanso magwiridwe antchito ake. Ufa wa latex wosinthika umagwira ntchito yowonjezera kusinthasintha ndi kusinthasintha kwa putty. Chifukwa cha mphamvu ya unyolo wa molekyulu wa ufa wa latex, putty imatha kukhala yolimba ikauma, ndipo imatha kusintha pang'ono pamwamba pa nthaka, potero imachepetsa ming'alu yomwe imabwera chifukwa cha zinthu monga kusintha kwa kutentha ndi kusinthasintha kwa chinyezi. Izi ndizofunikira kwambiri pakukongoletsa khoma ndi kukongola.
3. Kulimbitsa kukana madzi ndi kukana nyengo kwa putty
Ufa wa latex ukhoza kupititsa patsogolo kukana madzi kwa putty mwa kuwonjezera kuopsa kwa madzi kwa putty. Putty yachikhalidwe imayamwa madzi mosavuta komanso imatupa pamalo onyowa, zomwe zimapangitsa kuti putty ichotsedwe ndikuumba. Mukawonjezera ufa wa latex womwe ungathe kusungunukanso, mphamvu ya putty yoyamwa madzi imachepa kwambiri, ndipo imatha kupirira kuwonongeka kwa madzi pang'ono. Kuphatikiza apo, kuwonjezera ufa wa latex kumathandizanso kukana kwa putty nyengo, kotero kuti putty ikhoza kukhalabe ndi magwiridwe antchito abwino ikakhala nthawi yayitali pamalo ovuta monga mphepo, mvula ndi dzuwa.
4. Kuwongolera magwiridwe antchito a putty
Ufa wa latex wosungunukanso ungathandize kuti putty igwire bwino ntchito yomanga. Kuwonjezera ufa wa latex kumapangitsa kuti putty ikhale yosavuta kugwiritsa ntchito, kuchepetsa kuuma ndi mphamvu ya ntchito yomanga. Kusinthasintha ndi kugwira ntchito kwa putty kudzakhala bwino, ndipo kusalala ndi kumamatira kwa chophimbacho kungawongoleredwe. Ufa wa latex umapangitsa putty kukhala ndi mphamvu yochepetsera pang'onopang'ono panthawi yowuma, kupewa ming'alu kapena kuphimba kosagwirizana komwe kumachitika chifukwa cha kuumitsa kwa putty mwachangu panthawi yomanga.
5. Kulimbitsa kukana kwa chisanu kwa putty
M'malo ozizira, putty imatha kutaya ntchito yake yoyambirira chifukwa cha kutentha kochepa, komanso kuyambitsa mavuto monga kusweka ndi kugwa. Kuwonjezera ufa wa latex wosungunukanso kungathandize kwambiri kukana chisanu cha putty. Ufa wa latex ukhoza kusunga kukhazikika bwino kwa kapangidwe kake pansi pa kutentha kochepa ndikupewa mavuto abwino a putty chifukwa cha kuzizira. Chifukwa chake, kugwiritsa ntchito ufa wa latex wokhala ndi putty m'malo ozizira monga kumpoto kungathandize kwambiri kukhazikika ndi kudalirika kwa chinthucho.
6. Chepetsani ma porosity ndikuwonjezera kuchuluka kwa putty
Kuonjezera ufa wa latex kungachepetse bwino kukhuthala kwa putty ndikuwonjezera kuchuluka kwa putty. Pakupanga filimu ya putty, ufa wa latex ungadzaze ming'alu yaying'ono mkati mwa putty, kuchepetsa kulowa kwa mpweya ndi madzi, ndikuwonjezera kukana kwa madzi, kukana kuipitsa komanso kukana kwa putty. Kukhuthala kwa putty kumakhudza kwambiri kulimba kwa khoma lonse, ndipo kumatha kukweza bwino mtundu wa khoma mutagwiritsa ntchito nthawi yayitali.
7. Kupititsa patsogolo mphamvu ya putty yoletsa kuipitsa
Putty layer ndiye maziko a utoto. Kukumana ndi fumbi, mafuta, zinthu za acidic ndi alkaline kwa nthawi yayitali mumlengalenga ndi zinthu zina zoipitsa kudzakhudza zotsatira zomaliza za utoto. Ufa wa latex womwe umasungunukanso umathandiza kuchepetsa mphamvu ya madzi pamwamba pa putty, motero kuchepetsa kumamatira kwa zinthu zoipitsa. Izi sizimangowonjezera kulimba kwa putty, komanso zimasunga kukongola kwa utoto wa pakhoma.
8. Wonjezerani makulidwe a kapangidwe ka putty
Popeza ufa wa latex ukhoza kupititsa patsogolo bwino ntchito yomangirira komanso kusinthasintha kwa putty, putty pogwiritsa ntchito ufa wa latex nthawi zambiri imatha kuthandizira makulidwe akuluakulu a zomangamanga. Izi ndizofunikira kwambiri pamakoma ena omwe amafunikira makulidwe akulu kuti akonze, zomwe zingatsimikizire kuti khoma lokonzedwalo limakhala losalala komanso losasweka mosavuta pakugwiritsa ntchito nthawi yayitali.
Mphamvu yaufa wa latex wosungunukansoPa putty pali zinthu zambiri, makamaka zomwe zimaonekera pokonza kumatirira, kusinthasintha, kukana madzi, kukana chisanu, magwiridwe antchito omangira komanso kupewa kuipitsa kwa putty. Monga chosinthira chabwino kwambiri, ufa wa latex sungangowonjezera ubwino wa putty ndikuwonjezera kulimba kwake, komanso umapangitsa kuti putty ikhale yosinthika m'malo osiyanasiyana omangira. Pamene makampani omanga nyumba akufunikira kuti pakhale ubwino womangira makoma, kugwiritsa ntchito ufa wa latex wosungunukanso kudzakula kwambiri, ndipo zotsatira zake pa zinthu za putty zidzakhala zazikulu.
