Hnub no yog lub sijhawm ntawm kev vam meej. Nws kov txhua qhov chaw ntawm lub neej. Cov khoom siv hauv tsev tshiab thiab niaj hnub tshwm sim txhua hnub. Ib qho ntawm cov no yog cov tshiab polymer-based putty. Qhov sib tov no yog qhov zoo. Qhov zoo ntawm polymer putty piv rau cov khoom siv hauv tsev yog dab tsi?
Cov khoom siv niaj hnub no yog dab tsi
Ua ntej tham txog qhov kev sib xyaw thev naus laus zis no yog dab tsi, nws tsim nyog nrhiav seb lub hom phiaj ntawm putty. Nyob rau hauv cov tsev zoo tib yam, cov phab ntsa yog nyob rau hauv ib tug tsis zoo heev mob, txawm hais tias lawv tej zaum yuav zoo heev tsim. Feem ntau cov phab ntsa tsis ua raws li qhov yuav tsum tau ua thiab cov cai hauv tsev. Thiab dab tsi yog qhov tseem ceeb tshaj plaws rau cov phab ntsa? Kev sib tw. Nws yog los ntawm tus yam ntxwv no tias qhov zoo ntawm cov phab ntsa yog txiav txim siab. Txawm hais tias nws zoo li tias qhov sib npaug zoo tag nrho, nws yog qhov tseeb. Lawm, muaj kev zam, tab sis nws yeej tsis mob kom ua tiav phab ntsa nrog putty.
Polymer putty yog cov tshuaj tshiab hauv kev tsim kho kev lag luam. Xws li kev sib tov tau dhau los ua neeg nyiam heev hauv lub sijhawm luv luv vim lawv cov yam ntxwv. Cov nolub tsev compositions yog haum rau ob qho tib si sab hauv tsev thiab sab nraum zoov ua hauj lwm. Lawv muaj cov cim khi polymers.
Hom ntawm polymer tsev sib tov
Hnub no, ob hom kev sib xyaw no tuaj yeem pom ntawm lub khw muag khoom. Qhov no yog acrylic thiab latex putty. Txhua qhov sib tov muaj cov yam ntxwv tshwj xeeb thiab tuaj yeem siv rau qee hom kev ua haujlwm.
Acrylic putty
Qhov no yog ib qho ntawm cov khoom siv dav siv ntawm cov khoom sib xyaw polymer putty. Cov khoom no muaj ntau yam thiab tuaj yeem siv rau ntau yam haujlwm. Feem ntau cov khoom siv no yog siv rau kev kho kom zoo nkauj sab hauv, tab sis nws kuj yog ib qho kev xaiv zoo heev rau kev ua haujlwm sab nraum zoov.
Ib yam ntawm cov yam ntxwv yog kev ua kom zoo meej ntawm phab ntsa. Qhov sib tov tuaj yeem siv tau ua tiav. Yog tias koj xav tau theem ntawm phab ntsa, tab sis nws tsis paub meej tias yuav siv dab tsi, ces acrylic putty yog cov cuab yeej thoob ntiaj teb uas yuav ua haujlwm tau zoo.
Luas Blends
Yog cov khoom siv acrylic yog cov tshuaj universal, ces cov pab pawg no tsuas yog siv rau sab hauv tsev. Ib qho ntawm cov yam ntxwv yog qhov tsis muaj qhov tsis hnov tsw. Kev sib xyaw ua ke yooj yim rau kev thov thiab muaj lub neej ua haujlwm ntev.
Acrylic putties: txhua yam koj yuav tsum paub
Lub ntsiab tseem ceeb hauv hom kev sib xyaw no yog acrylic. Qhov no yog ib yam khoom tshwj xeeb uas nws cov yam ntxwv ua tauhloov. Cov polymer no cuam tshuam zoo nrog lwm cov khoom sib xyaw. Cov muaj pes tsawg leeg yog homogeneous loj, uas, tom qab ziab, ua kom du thiab ntom ntom.
Muaj ntau yam khoom zoo sib xws. Piv txwv li, facade putties yog qhov tsim nyog tshaj plaws rau kev ua haujlwm ntawm sab nrauv phab ntsa thiab hauv pem teb. Moisture-resistant putty yog siv los ua tiav cov pob zeb ua vaj tse, nrog rau cov ntoo nto.
Nyob ntawm cov khoom hauv qhov sib tov, cov khoom siv hauv tsev no tau muab faib ua qhov pib thiab ua tiav. Pib txheej txheej yog tsim raws li cov qauv tsim los nkaum qhov tsis xws luag thiab qib sib txawv. Polymer finishing putty tsuas yog tsim nyog rau kev kho kom zoo nkauj zaum kawg.
Cov ntaub ntawv tiav no yog siv rau txhua yam ntawm qhov chaw, tab sis kuj tseem muaj cov khoom sib xyaw tshwj xeeb ntawm kev muag khoom rau kev ua haujlwm ntawm ntoo, pob zeb, phab ntsa ntub dej thiab txawm tias hlau.
A universal putty kuj muaj. Nws yog qhov tsim nyog rau kev ua tiav facades, nrog rau kev ua haujlwm sab hauv. Cov khoom no kuj tsim nyog rau cov plag tsev thiab ntau hom ntawm qhov chaw.
Cov lus pom zoo rau kev siv cov khoom siv acrylic
Lub sijhawm ziab rau cov khoom siv hauv tsev no yog li 24 teev, tab sis daim duab no yuav txawv thiab nyob ntawm hom kev sib xyaw thiab cov chaw tsim khoom. Koj tuaj yeem ua haujlwm nrog cov ntaub ntawv no tsuas yog ntawm qhov kub zoo - hauv Frost, lub polymer putty poob nws elasticity.
Siv cov khoom siv rau qhov chaw ua haujlwm hauv txheej nyiaslos ntawm 1 mus rau 3 mm. Yog tias tsim nyog rau theem phab ntsa kom txaus, ces txhua txheej yuav tsum tsis txhob tuab dua 10 hli.
Yog tias koj xav kho cov ntoo saum npoo, ces acrylic sib tov yog qhov zoo rau qhov no. Ib qho ntawm cov yam ntxwv yog adhesion zoo nrog txhua yam ntaub ntawv. Tsis tas li ntawd, qhov tseeb hom putty sib tov tuaj yeem ua raws li cov qauv ntoo. Yog tias kev ua haujlwm hlau tau npaj, ces nws yog ib qho tseem ceeb uas yuav tsum xaiv cov xim zoo.
Ua haujlwm nrog cov khoom siv yuav tsum yog cov spatula feem ntau. Tab sis yog tias koj siv cov kuab tshuaj thiab dilute cov muaj pes tsawg leeg, koj tuaj yeem siv airbrush. Cov khoom yog muag hauv daim ntawv npaj siv.
Koj tuaj yeem siv cov khoom no rau ob qho tib si pib thiab ua tiav. Nws tsis pom zoo kom knead lub putty tam sim ntawd nyob rau hauv loj ntim - cov muaj pes tsawg leeg thickens sai sai thiab poob nws cov yam ntxwv.
Qhov zoo thiab qhov tsis zoo
Acrylic universal putty muaj adhesion zoo rau txhua hom ntawm qhov chaw. Nws kuj yog heev resistant rau ntau yam deformations, muaj siab elasticity. Cov khoom sib tov no tiv taus cov hluav taws xob ultraviolet, kom kub siab, mus rau Frost. Tsis tas li ntawd, lawv nco txog qib siab ntawm kev tiv thaiv kom ya raws, nrog rau cov yam ntxwv zoo thermal rwb thaiv tsev.
Raws li koj tuaj yeem pom, cov tsev sib xyaw no muaj ntau qhov zoo. Tab sis kuj muaj ob peb downsides.
Qhov tsis zoo tseem ceeb yog tus nqi. Ib tug zoo polymer-raws li putty yog kim heev, tab sis buyerstxaus siab rau qhov zoo ntawm cov khoom tshiab no. Rau cov neeg uas tsis xav txuag nyiaj, qhov no yog qhov kev xaiv zoo tshaj plaws. Tsis tas li ntawd, ib qho ntawm cov yam ntxwv yog lub neej ua haujlwm ntev ntawm cov txheej.
Lwm qhov tsis zoo yog qhov xav tau rau kev xuab zeb tom qab lub putty qhuav. Cov txheej txheem sib tsoo yuav tso tawm ntau cov hmoov av zoo rau hauv huab cua, uas tuaj yeem ua rau muaj kev phom sij rau kev noj qab haus huv.
Latex putty: yam ntxwv thiab nta
Latex blends muaj qhov sib xws rau cov khoom siv acrylic. Cov khoom tseem ceeb ntawm no yog latex. Cov khoom siv yog elastic heev thiab yog li ntawd muaj zog heev, ruaj thiab resistant rau ib puag ncig influences.
Qhov no polymer putty kuj muag npaj ua. Yog tias koj ntxiv cov xim rau qhov sib tov, ces koj tau txais ib yam khoom ntawm qhov xav tau ntxoov ntxoo. Tus nqi ntawm cov khoom no yog siab heev, tab sis yog tias koj kho nrog cov ntaub ntawv no, ces koj yuav tsis tau rov qab nto rau lub sij hawm ntev heev.
Tus yam ntxwv tseem ceeb yog ua kom muaj zog tiv thaiv kom ya raws. Moisture-resistant putty dries sai sai thiab muaj adhesion zoo heev. Cov khoom no tuaj yeem siv rau kev ua haujlwm tiav ntawm facades lossis hauv chav nrog cov av noo siab.
Qhov twg zoo dua - gypsum lossis polymer sib xyaw?
Hnub no, gypsum compositions yog nrov li cov khoom tiav. Tsis muaj dab tsi xav tsis thoob ntawm no. Gypsum putties muaj ntau qhov zoo. Lawv muaj adhesion zoo, siab durability, lub zog. Tshem tawm -tsis muaj peev xwm ua haujlwm hauv chav ntub dej.
Kev xaiv cov khoom tiav yog nyob ntawm seb hom kev ua haujlwm yuav tsum tau ua tiav. Gypsum khoom yog qhov zoo tagnrho rau cov phab ntsa ntub dej. Rau lwm qhov chaw, nws yog qhov zoo dua los xaiv cov khoom sib xyaw polymer - tus nqi siab dua, tab sis qhov zoo dua.
Tsim kev sib xyaw "Hercules"
Lub tuam txhab no tsim GT-73 waterproof polymer putty. Qhov sib tov yog npaj rau kev ua tiav ntau yam tsis xws luag ntawm pob zeb lossis cellular pob zeb. Cov khoom no zoo tagnrho rau kev siv sab hauv tsev thiab sab nraum zoov. Tshwj xeeb tshaj yog pom zoo polymer putty "Hercules" rau chav ntub dej.
Cov khoom siv hauv tsev niaj hnub tau dhau los ua cov thev naus laus zis ntau dua. Lawv yooj yim rau siv, thiab qhov zoo ntawm qhov tshwm sim yog heev, siab heev. Koj yuav tsum tau sim cov khoom siv polymer no.
