Latex poda-Kuvandudza kuenderana uye kutsvedza kweiyo sisitimu munzvimbo yekunyorova yekusanganisa. Pamusana pemaitiro epolymer, kubatanidzwa kwemvura inosanganiswa zvinhu inovandudzwa zvikuru, iyo inobatsira zvikuru pakushanda; mushure mekuomeswa, inopa kunamatira kune yakatsetseka uye dense yepamusoro. Relay, gadzirisa chimiro chejecha, matombo uye pores. Pasi pemamiriro ekusimbisa huwandu hwekuwedzera, inogona kupfumiswa kuita firimu pane iyo interface, kuitira kuti tile yekunamatira ine imwe shanduko, inoderedza elastic modulus, uye inotora iyo thermal deformation stress kusvika pamwero mukuru. Kana kuri kunyudzwa mumvura mune yakazotevera nhanho, pachave nezvinonetsa senge kusamira kwemvura, tembiricha yebhafa, uye kusagadzikana kwezvinhu deformation (tile deformation coefficient 6 × 10-6 / ℃, simende kongiri deformation coefficient 10 × 10-6 / ℃) , uye kunatsiridza kusamira kwemamiriro ekunze. Hydroxypropyl Methyl Cellulose HPMC-Ipa kuchengetedzwa kwakanaka kwemvura uye kushanda kwedhaka nyowani, kunyanya kunzvimbo yakanyorova. Kuti ive nechokwadi chekufambira mberi kwakatsetseka kweiyo hydration reaction, inogona kudzivirira iyo substrate kubva kune yakawandisa kunyura kwemvura uye iyo yepamusoro layer kubva pakubuda. Nekuda kweiyo mhepo-inopinza midziyo (1900g/L—-1400g/LPO400 jecha 600HPMC2), kuwanda kwematairi anonamira kwakaderedzwa, kuchengetedza zvinhu uye kuderedza elastic modulus yedhaka rakaomarara.
Tile adhesive redispersible latex poda igirini, ine hushamwari, inovaka inochengetedza simba, yakakwirira-yemhando yakawanda-inoshandiswa poda yekuvaka zvinhu, uye yakakosha uye yakakosha inoshanda yekuwedzera kune yakaoma-yakasanganiswa dhaka. Inogona kuvandudza kushanda kwedhaka, kuwedzera kusimba kwedhaka, kuwedzera kusimba kwechisungo pakati pedhaka uye akasiyana-siyana substrates, kunatsiridza kuchinjika uye kushanda, kumanikidza simba, flexural simba, kupfeka kuramba, kusimba, uye viscosity yedhaka. Relay uye mvura yekuchengetedza simba, constructability. Kuita kweiyo tile adhesive redispersible latex poda ine simba, uye tile inonamira inodzokororwa latex poda ine yakakwirira yekubatanidza kugona uye yakasarudzika zvimiro. Naizvozvo, huwandu hwavo hwekushandisa hwakakura zvakanyanya. Basa re hydroxypropyl methylcellulose rinoita basa rekuchengetedza mvura, kukora uye kuita kwekuvaka mukutanga nhanho, uye redispersible latex poda yekunamatira mataira inoita basa resimba mune inotevera nhanho, iyo inoita basa rakanaka kwazvo mukusimba, acid. uye alkali kuramba kweprojekiti. Mhedzisiro yeadhesive adhesive redispersible latex poda padhaka nyowani: kurebesa nguva yekushanda uye gadzirisa nguva yekuvandudza mashandiro ekuchengetedza mvura, kuitira kuti ive nechokwadi chekuti hydration ye simende uye kuvandudza sag kuramba (special modified rubber powder) uye kugadzirisa kushanda (zviri nyore kushandisa Substrate ndeyekuvaka kwepamusoro, nyore kudzvanya mataira muchinamira) basa redhaka rakaomeswa rine kunamatira kwakanaka kune akasiyana substrates, kusanganisira kongiri, plaster, huni, mataira ekare, PVC kunyangwe pasi pemamiriro ekunze akasiyana siyana, ane yakanaka deformation kugona.
Kuwedzerwa kwe redispersible latex poda yekunamatira mataira kune mhedzisiro iri pachena pakuvandudzwa kwekuita kwesement-based tile adhesives, uye ine mhedzisiro yakakosha pakusimba kwekubatanidza, kusamira kwemvura, uye kuchembera kweanonamatira. Parizvino, kune marudzi akawanda eadhispersible latex powders ekunamira mataira pamusika, senge acrylic redispersible latex powders, styrene-acrylic powders, vinyl acetate-ethylene copolymers, etc. Kazhinji kutaura, matani anonamira anoshandiswa mumatairi anonamira pamusika. Mazhinji anodhindwa zvakare latex hupfu ndeye vinyl acetate-ethylene copolymers.
(1) Sezvo huwandu hwesimende huchiwedzera, simba rekutanga redispersible latex poda yekunamatira mataira inowedzera, uye panguva imwecheteyo, simba rekunamatira rekunamatira mushure mekunyudzwa mumvura uye kusimba kwekunamatira mushure mekukwegura kwekupisa kunowedzerawo.
(2) Nekuwedzera kwehuwandu hwekudhindwa kwelatex poda yekunamira kwetairi, iyo yakasimba bond simba redispersible latex poda yekunamatira mataira mushure mekunyudzwa mumvura uye kusimba kwechisungo mushure mekukwegura kwekupisa kwakawedzera zvinoenderana, asi kuchembera kwemafuta Mushure meizvozvo. , iyo tensile bond simba yakawedzera zvakanyanya.
Nekuda kwemaitiro ayo akanaka ekushongedza uye anoshanda akadai sekusimba, kudzivirira kwemvura uye kuchenesa nyore, mataira e ceramic anoshandiswa zvakanyanya: kusanganisira madziro, pasi, sirin'i uye madziva ekushambira, nezvimwewo, uye anogona kushandiswa mukati uye kunze. Nzira yechinyakare yekumisikidza mataira ndiyo yakakora-layer nzira yekuvaka, kureva kuti, tanga waisa dhaka rakajairwa kuseri kwematairi, wobva wadzvanya mataira kune base layer. Ukobvu hwedhaka redhaka hunenge 10 kusvika 30mm. Kunyange zvazvo nzira iyi yakanyatsokodzera kuvakwa pazvigadziko zvisina kuenzana, zvazvisirizvo ndezvokushomeka kwematairi ekuisa mataira, zvinodikanwa zvakanyanya zvehunyanzvi hwevashandi, njodzi yakawedzera yekudonha nekuda kwekusachinja-chinja kwedhaka, uye kuomerwa mukugadzirisa dhaka panzvimbo yekuvaka. . Hunhu hunodzorwa zvakanyanya. Iyi nzira inokodzera chete matiles ane yakakwirira yekunyudza mvura. Usati wanamira matiles, matiles anoda kunyikwa mumvura kuti awane kusimba kwechisungo chakakwana.
Parizvino, nzira yekuisa matairi inoshandiswa zvakanyanya muEurope ndiyo inonzi yakatetepa-layer yekunamira nzira, ndiko kuti, iyo polymer-yakagadziridzwa tile yekunamatira batch inokweshwa pamusoro peiyo base layer kuti ifanoiswa mataira nemazino spatula kuti. gadzira mitsetse yakasimudzwa. Uye iyo dhaka dhizaini yeukobvu hweyunifomu, wobva wadzvanya matiles pairi uye shandura zvishoma, ukobvu hwedhaka redhaka hunenge 2 kusvika 4mm. Nekuda kwekugadziriswa kwe cellulose ether uye redispersible latex poda, kushandiswa kweiyi adhesive yekunamira kune yakanaka yekubatanidza kuita kune akasiyana marudzi echigadziko maseru uye pamusoro pezvikamu zvinosanganisira zvizere vitrified mataira ane kuderera kwakanyanya kwemvura, uye ine Yakanaka kuchinjika, kuitira kuti itore. kushushikana kunokonzerwa nezvinhu zvakaita senge tembiricha musiyano, uye yakanakisa sag kuramba, yakaringana yakavhurika nguva yekutetepa-layer kuvaka, iyo inogona kukurumidzira zvakanyanya kumhanya kwekuvaka, nyore kushanda uye hapana chikonzero chekufanonyorovesa matiles mumvura. Iyi nzira yekuvaka iri nyore kushanda uye iri nyore kuita pa-saiti kuvaka kwemhando yekutonga.
