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 kunyudzwa kwemvura muchikamu chekupedzisira, pachava nezvinonetsa senge kusamira kwemvura, tembiricha yebhafa, uye kusagadzikana kwezvinhu deformation (tile deformation coefficient 6 × 10-6 / ℃, simende kongiri deformation coefficient 10 × 10-6 / ℃), uye kugadzirisa mamiriro 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, uye redispersible latex poda yekunamatira tile inoita basa resimba muchikamu chekupedzisira, icho chinoita basa rakanaka kwazvo mukusimba, asidhi 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 yesimende uye nekuvandudza sag kuramba (yakakosha yakagadziridzwa rubha poda) uye kugadzirisa kushanda (nyore kushandisa Substrate iri pamusoro pekuvaka, nyore kudzvanya matiles muchinamira, dhaka rekongiri rakasiyana-siyana rinosanganisira dhaka rakaomeswa). 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 ehupfu hwematairi anodhindwa pamusika, akadai se acrylic redispersible latex powders, styrene-acrylic powders, vinyl acetate-ethylene copolymers, etc. Kazhinji kutaura, matilesi anonamira anoshandiswa mumatairi anonamira pamusika Most redispersible latexlex polypolymers.
(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 hwehupfu hwehuputi hunogadziriswa hwekunamatira tile, simba rekubatanidza redispersible latex poda yekunamatira tile mushure mekunyudzwa mumvura uye kusimba kwechisungo mushure mekukwegura kwekupisa kwakawedzera zvichienderana, asi kuchembera kwekushisa Mushure mezvo, simba rekubatanidza rinowedzera 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, zvazvakaipira kuderera kwekushanda kwematairi, zvinodiwa zvakanyanya zvehunyanzvi hwevashandi, njodzi yakawedzera yekudonha nekuda kwekusachinja-chinja kwedhaka, uye kuomerwa mukugadzirisa dhaka panzvimbo yekuvakira. 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 yakaonda-layer sticking method, kureva kuti, iyo polymer-modified tile adhesive batch inokweshwa pamusoro pechigadziko chegadziko kuti chifanoiswa mataira pachine mazino spatula kuita 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 kweiyo tirairi yekunamira kune yakanaka bonding performance kune dzakasiyana siyana dze base layers uye pamusoro pezvikamu zvinosanganisira zvizere vitrified tiles ine yakaderera mvura inonzva, uye ine yakanaka kuchinjika, kuitira kuti itore kushushikana kunokonzerwa nezvinhu zvakaita sekusiyana kwetembiricha, uye yakanakisa sag kupikisa, kureba kuvhurika kukurumidza kukurumidza kuvaka, kutetepa kukurumidza kukurumidza kuvaka, kukurumidza kuvhurika uye kukurumidza kukurumidza kuvaka. hapana chikonzero chekufanonyorova matiles mumvura. Iyi nzira yekuvaka iri nyore kushanda uye iri nyore kuita pa-saiti yekuvaka yemhando yekutonga.
