1. Putty inoshandiswa sechinhu chekugadziriswa kwepamusoro kuti ipfekedzwe mumachira ekuvaka.
Putty ivhu rakatetepa redhaka rekuyera. Putty inokweshwa pamusoro penzvimbo dzakakasharara (zvakadai sekongiri, dhaka rekuenzanisa, gypsum board, zvichingodaro) Ita kuti pendi yepende yekunze iite yakatsetseka uye yakapfava, isiri nyore kuunganidza guruva uye nyore kuchenesa (izvi zvinonyanya kukosha kunzvimbo dzine kusvibiswa kwemhepo kwakanyanya). Putty inogona kukamurwa kuita chimwe-chikamu putty (paste putty paste uye yakaoma poda putty poda) uye maviri-chikamu putty (inoumbwa putty poda uye emulsion) zvinoenderana neyakapedzwa chigadzirwa fomu. Nekutarisisa kwevanhu kune tekinoroji yekuvaka yeavakiteki, putty sechinhu chakakosha chekutsigira chakagadzirwawo saizvozvo. Vagadziri vakasiyana-siyana vekumba vakatevedzana vakagadzira putty nezvinangwa zvakasiyana uye akasiyana mafomu, senge poda putty, paste putty, yemukati madziro putty Putty, yekunze madziro putty, elastic putty, nezvimwe.
Tichitarisa kubva pakushandiswa chaiko kwembambo yekuvakisa coatings, pane kazhinji zvinokanganisa senge kupupa furo uye peeling, izvo zvinokanganisa zvakanyanya kudzivirira uye kushongedzwa kwekuita kwejasi pazvivakwa. Pane zvikonzero zviviri zvakakosha zvekukuvadzwa kweiyo firimu yekuputira:
Imwe imhando yepende;
Yechipiri inobata zvisina kunaka substrate.
Kudzidzira kwakaratidza kuti inopfuura 70% yekutadza kwekupfeka ine hukama nehurombo hwe substrate kubata. Putty yekugadzira machira yakave yakashandiswa zvakanyanya seyakagadzirwa zvinhu zvepamberi pretreatment kuti ipfekedzwe. Iyo haigone chete kutsvedzerera uye kugadzirisa pamusoro pezvivakwa, asiwo yemhando yepamusoro putty inogona kusimudzira zvakanyanya kudzivirira uye kushongedza kuita kwekuvhara pazvivakwa. Kuwedzera hupenyu hwesevhisi yejasi chinhu chakakosha chinotsigira chigadzirwa chepamusoro-chinoshanda chekuvaka machira, kunyanya ekunze emadziro emadziro. Iyo imwechete-chikamu chakaoma poda putty ine zviri pachena zvehupfumi, hunyanzvi uye zvakatipoteredza zvakanakira mukugadzira, chekufambisa, kuchengetedza, kuvaka uye zvichingodaro.
Ongorora: Nekuda kwezvinhu zvakaita senge mbishi zvinhu uye mutengo, inorasika yepolymer poda inonyanya kushandiswa mu-anti-cracking putty poda yemadziro ekunze, uye zvakare inoshandiswa mune yepamusoro-giredhi yemukati madziro ekupukuta putty.
2. Basa rekudzivirira-kuputika putty kumadziro ekunze
Ekunze madziro putty anowanzo shandisa simende seye inorganic bonding material, uye shoma shoma yeash calcium inogona kuwedzerwa kuti iwane synergistic effect. Basa resimende-based anti-cracking putty kumadziro ekunze:
Iyo yepamusoro layer putty inopa yakanaka base, iyo inoderedza huwandu hwepende uye inoderedza mutengo wepurojekiti;
Putty ine kunamatira kwakasimba uye inogona kunyatsobatanidzwa kumadziro epasi;
Iine kumwe kuomarara, inogona kunyatso vhara mhedzisiro yekuwedzera kwakasiyana uye kudonhedza kushushikana kweakasiyana base layer, uye ine yakanaka kutsemuka kuramba;
Putty ine yakanaka yemamiriro ekunze kuramba, kusamira, hunyoro kuramba uye nguva yakareba sevhisi;
Yakanaka zvakatipoteredza, isina chepfu uye yakachengeteka;
Mushure mekugadziriswa kwezvinowedzera zvinoshanda, senge putty rubber poda uye zvimwe zvinhu, iyo yekunze madziro putty inogona zvakare kuve neanotevera mabhenefiti anoshanda:
Basa rekukwenya rakananga pakupera kwekare (pende, tile, mosaic, dombo uye mamwe madziro akatsetseka);
Yakanaka thixotropy, inenge yakakwana yakatsetseka yepamusoro inogona kuwanikwa nekungozora, uye kurasikirwa kunokonzerwa neakawanda-kushandisa machira nekuda kwekusaenzana kwepasi pasi kunoderedzwa;
Iyo elastic, inogona kuramba micro-cracks, uye inogona kugadzirisa kukuvadzwa kwekushushikana kwekushisa;
Yakanaka yekudzivirira mvura uye basa rekusapinda mvura.
3. Basa redispersible latex powder mukunze kwemadziro putty powder
(1) Mhedzisiro yeputty rubber poda pane ichangobva kusanganiswa putty:
Kuvandudza kushanda uye kuvandudza putty batch scraping performance;
kuwedzera kuchengetwa kwemvura;
kuwedzera kushanda;
Dzivisa kukurumidza kutsemuka.
(2) Mhedzisiro yeputty rubber poda pane yakaomeswa putty:
Deredza iyo elastic modulus ye putty uye wedzera kuenderana kune base layer;
Kuvandudza iyo micro-pore chimiro chesimende, kuwedzera kuchinjika mushure mekuwedzera putty rubber poda, uye kuramba kuputika;
Kuvandudza kupikisa kwehupfu;
Hydrophobic kana kuderedza kunyura kwemvura kweputty layer;
Wedzera kunamatira kwe putty kumadziro epasi.
Chechina, zvinodiwa zvekunze kwemadziro putty kuvaka process
Putty kuvaka maitiro anofanirwa kutarisisa kune:
1. Pesvedzero yemamiriro ekuvaka:
Kufurira kwemamiriro ekuvaka kunonyanya kudziya uye hunyoro hwenzvimbo. Mumamiriro okunze anopisa, chigadziko chepasi chinofanira kupfapfaidzwa nemvura, kana kuchengetwa chakanyorova, zvichienderana nekushanda kweiyo chaiyo putty poda chigadzirwa. Sezvo kunze kwemadziro putty poda inonyanya kushandisa simende sesimende zvinhu, ambient tembiricha inodiwa kuti isadzike kupfuura 5 madhigirii, uye haizoomerwe nechando isati yaoma mushure mekuvaka.
2. Gadziriro uye zvidziviriro usati wachera putty:
Zvinodikanwa kuti basa guru rakapedzwa, uye chivako nedenga zvapedzwa;
Zvose zvakabatanidzwa zvikamu, magonhi, mahwindo uye mapaipi echigadziko chedota zvinofanira kuiswa;
Kuti udzivise kusvibiswa uye kukuvadza kune zvakapedzwa zvigadzirwa mubatch scraping process, zvinhu zvekudzivirira zvakananga uye zviyero zvinofanirwa kugadziriswa pamberi pebatch scraping, uye zvikamu zvakakodzera zvinofanira kuvharwa nekuputirwa;
Kuiswa kwehwindo kunofanirwa kuitwa mushure mekunge putty batch yaputswa.
3. Kurapwa kwepamusoro:
Pamusoro pe substrate inofanira kuva yakasimba, yakadzikama, yakaoma uye yakachena, isina mafuta, batik nezvimwe zvinhu zvakasununguka;
Kumusoro kwepurasita kutsva kunofanirwa kupora kwemazuva gumi nemaviri isati yaputswa, uye iyo yekutanga plastering layer haigone kuiswa calender nesamende paste;
Kana rusvingo rwakanyanya kuoma kusati kwavakwa, rusvingo runofanira kunyoroveswa mberi.
4. Maitiro ekushanda:
Dururira huwandu hwakakodzera hwemvura mumudziyo, wobva wawedzera pakaoma putty poda, uye wozonyatso simbisa nemuvhenganisi kusvika yava yunifomu paste isina poda particles uye kunaya kwemvura;
Shandisa batch scraping tool ye batch scraping, uye yechipiri batch scraping inogona kuitwa mushure mokunge yekutanga ye batch embedding yapera kwemaawa anenge 4;
Pera iyo putty layer zvakanaka, uye dzora ukobvu kuti huite 1.5mm;
Iyo simende-based putty inogona kupendwa ne-alkali-resistant primer chete mushure mekunge kupora kwepanyama kwapera kusvikira alkalinity uye simba zvasangana nezvinodiwa;
5. Notes:
Iyo verticality uye flatness ye substrate inofanira kugadziriswa isati yavakwa;
Iyo yakasanganiswa putty mortar inofanira kushandiswa mukati me1 ~ 2h (zvichienderana nefomu);
Usasanganise iyo putty mortar yakapfuura nguva yekushandisa nemvura usati waishandisa;
Inofanira kukwenenzverwa mukati me1 ~ 2d;
Kana iyo base yepasi yakaverengerwa nesamende dhaka, zvinokurudzirwa kushandisa interface kurapwa mumiriri kana interface putty uye elastic putty.
Chiyero cheredispersible polymer podainogona kureva iyo dosage data mune fomula yekunze madziro putty poda. Zvinokurudzirwa kuti vatengi vaite akati wandei akasiyana madiki ekuyedza asati agadzirwa kuti ave nechokwadi chemhando yeputty poda.
