Basa reredispersible polymer podamukuvakaindasitiri haigone kurerutswa. Sechinhu chinoshandiswa zvakanyanya chekuwedzera, zvinogona kutaurwa kuti kutaridzika kwepolymer inodzoreredzwa hupfu yakavandudza kunaka kwekuvaka neanopfuura giredhi rimwe. Chinhu chikuru che redispersible polymer hupfu ndeye organic macromolecular polymer ine zvinhu zvakagadzikana. Panguva imwecheteyo, PVA inowedzerwa sechidziviriro colloid. Inowanzoita upfu pane imwe tembiricha. Iko kugona kwekunamatira kwakasimba kwazvo uye kuita kwekuvaka kwakanaka zvakare. Uye zvakare, iyi mhando yepolymer poda inogona zviripachena kuvandudza kupfeka kuramba uye kunyudzwa kwemvura kuita kwemadziro nekusimudzira kubatana kwedhaka. Panguva imwecheteyo, simba rekubatana uye deformability zvakare ndeyechokwadi. dhigirii rekuvandudza.
Redispersible latex podaigirini, nharaunda ine hushamwari, inovaka inochengetedza simba, yepamusoro-soro yakawanda-chinangwa podazvokuvakisa, uye chinhu chakakosha uye chakakosha chinoshanda chekuwedzerayakaoma-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 kwe redispersible latex poda mukatitile adhesiveine simba rakati, uye redispersible latex poda ine yakakwirira yekubatanidza kugona uye yakasarudzika zvimiro.
Latex hupfuinovandudza kuwirirana uye kutsetseka kwegadziriro mumamiriro ekunyorova kusanganisa. Pamusana pemaitiro epolymer, kubatanidzwa kwemvura yakasanganiswa zvinhu inovandudzwa zvikuru, uye inobatsira zvikuru pakushanda; mushure mekuoma, inopaadhesion kune yakatsetseka uye yakaomeswa pamusoro pedhiri, Kuvandudza iyo interface maitiro ejecha, matombo uye pores. Pasi pechimiro chekusimbisa huwandu hwekuwedzera, inogona kupfumiswa kuita firimu pane interface, kuitira kuti tile yekunamatira ine imwe shanduko, inoderedza elastic.odulus, 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.
Kuwedzerwa kweredispersible latex powder mumatairi adhesives kune mhedzisiro yakajeka pakuvandudzwa kwekuita kwesement-based tile adhesives, uye ine mhedzisiro yakakosha pakusimba kwekubatanidza, kusamira kwemvura, uye kuchembera kuramba kweadhesive. Kune marudzi akawanda ehupfu inodispersible latex poda yekunamira mataira pamusika, senge acrylic redispersible latex powder, styrene-acrylic powder, vinyl acetate-ethylene copolymer, etc. Kazhinji kutaura, matani anonamira anoshandiswa mumatairi anonamira pamusika anogona kuparadzirwa zvakare. . Mazhinji eiyo inorasika latex poda ndeyevinyl acetate-ethylene copolymer.
(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.
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, zvisizvo zvakaderera kushanda zvakanaka kwekuisa matairi, zvinodiwa zvikuru zvehunyanzvi hwevashandi, njodzi yakawedzera yekudonha nekuda kwekutadza kuchinjika kwedhaka, uye kuomerwa nekugadzirisa 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.
