Kare kuma1930s, mapolymer binders akashandiswa kuvandudza kushanda kwedhaka.Mushure mekunge mafuta epolymer aiswa pamusika zvinobudirira, Walker akagadzira nzira yekupfapfaidza yekupfapfaidza, iyo yakaona kupihwa kwemafuta ehupfu hwerabha, kukava kutanga kwenguva yepolymer yakagadziridzwa yakaoma yakasanganiswa dhaka.
Kwemakore anopfuura 100, mataira eceramic ave achishandiswa sekuvhara madziro uye pasi.Mazuva ano, dzave zvinhu zvekushongedza zvakakosha.Mataira ehukuru hwakasiyana, mapatani, uye mamakisi anogona kuoneka kwese kwese.Nekufambira mberi kweiyo ceramic tile tekinoroji, muviri wematairi eceramic uri kuramba wakakora uye kukura muhukuru, zvichiunza matambudziko makuru pakuiswa kwematairi e ceramic.Maitiro ekugadzira yakakura-saizi ceramic mataira anonamira zvakanyanya uye kuve nechokwadi chenguva refu yekuisa kuvimbika kwave kutsva kwekutarisa mumunda wekushongedza kwemazuva ano.Zvekunamira (zvakadai sepolymer) zvakanyoroveswa pamusoro pematairi eceramic, zvichigadzira mamiriro ekunyorova pakati pezviviri izvi, zvichikonzera kudiki diki kwema molecular spacing pakati pezviviri.Pakupedzisira, simba guru re intermolecular rinoumbwa panzvimbo yekubatanidza, inosungirira zvakasimba zvinhu zvekunamatira nekeramic tile.Nekufambira mberi kweiyo ceramic tile tekinoroji, inowedzera kuomarara mataira eceramic yakaoma kupa mamwe mapeji emakanika anopindirana kuita anchoring.Nekudaro, kubatana kwe intermolecular kuri kuwedzera kukosha.
Redispersible latex poda (RDP) inoumba polymer network mune zvigadzirwa zvedhaka, inobatanidza mataira nedhaka kuburikidza ne intermolecular forces.Kunyangwe kana mataira ari denser, anogona kuomerera kune dhaka.Redispersible latex poda inoumbwa nepolymerization yemapolymer maviri kana anopfuura, uye ine kuomarara kwakasiyana kunoenderana neakasiyana mativi ekuumbwa kwepolymer.Kana iri mukupisa kwepamusoro-soro, hupfu hwerabha hunoratidza madhigirii akasiyana-siyana ekunyorova nekuda kwekuoma kwayo.Kunyanya kuoma kwehupfu hwekunamatira, kuderedza dhigirii yekunyorova pane imwe tembiricha, uye kusimba kwekugona kupikisa masimba ekunze pakupisa kwakanyanya.Nokudaro, nokuda kwehupfu hwekunamatira hunoshandiswa mu ceramic tile adhesive, kukoshesa kunofanira kupiwa pakusarudza kuomarara kwehupfu hwehupfu, hunogona kunyatso chengetedza kunamatira kwenguva refu munzvimbo dzepamusoro-tembiricha.Paunenge uchishandisa nzira yakaonda yekuvaka yekugadzira mataira, kuitira kuti zvive nyore kuvaka, vashandi vachasarudza kuisa glue panzvimbo yakakura vasati vaenderera mberi nebasa rekuisa matairi.Munguva iyi, iyo ceramic tile inonamira inogadzira ganda panzvimbo yakafumurwa nekuda kwekumhanya kwemhepo yemhepo, substrate mvura yekunyudza, uye yemukati cellulose ether kupera uye kufamba.Nekuda kwekuti kunyorova ndiyo kiyi yekubatana kwepedyo kwezvinhu, kana goko racho rakaoma kuputsa, zvinozoita kuti zviome kuti tirairi yekunamatira inyorovese pasi tile, pakupedzisira ichikanganisa kusimba kwekubatanidza.Kusarudza redispersible latex poda, kune rumwe rutivi, nekuda kwechimiro chayo, inogona kuita rimwe basa mukuchengetedza mvura, kunonoka chiyero che hydration uye ganda.Kune rumwe rutivi, inogona kuvandudza simba rekunamatira pane imwe nzvimbo, kunyange kana nzvimbo yekupinda yakaderedzwa, inogona kuramba ichivimbisa simba rose rekunamatira.Panguva imwecheteyo, zvakakoshawo zvikuru kusarudza cellulose ether zvine musoro.Sezvo saizi yematairi eceramic inowedzera, zviri kuwedzera kuve nyore kuona gollowing uye kunyangwe kuitika kweceramic tile detachment mushure mekuisa.Iyi nyaya yakanyatsoenderana nekushanduka kwezvinhu zvekubatanidza.Ceramic mataira ane yakakwira density uye yakaderera deformation, uye base layer inogona kuwana yakakosha deformation nekuda kweakasiyana ekunze uye emukati zvinhu.Iyo ceramic tile adhesive inoshandiswa sechisungo chekubatanidza inofanirwa kukwanisa kutora kushushikana kunokonzerwa ne deformation.Kana iyo ceramic tile adhesive isina adhesive poda kana ine yakaderera yemukati yeadhesive poda, zvichave zvakaoma kutora kushushikana kunokonzerwa ne deformation, zvichiita kuti iyo yose paving system inodonha zvishoma nezvishoma pane isina simba, ichigadzira madhiramu maburi.
Redispersible latex poda inogona kupa tile inonamira nekugona kuchinjika kune kusagadzikana deformation, iyo inovandudza kuchinjika kweiyo tile yekunamatira.Muchirongwa ichi, kuomarara kweceramic tile adhesive kunonyanya kupihwa neinorganic zvinhu semendi nejecha, nepo kuchinjika kunopihwa nehupfu hwekunamatira.Polymer inopinda nemumapores esimende ibwe, ichigadzira polymer network inoshanda senge elastic bond pakati pezvinhu zvakaomarara, ichipa kuchinjika.Kana deformation ikaitika, iyo polymer network inogona kutora kushushikana, kuve nechokwadi chekuti zvinhu zvakaomarara hazvitseki kana kukuvadza.Naizvozvo, kuvandudza kuchinjika kwezvinhu zvekunamira kwakakosha pakudzikisa gorofu.Huwandu hwakakodzera hwehupfu hwekunamatira hunogona kuvandudza kuumbwa kwetiweki chimiro chepolymer mukati meiyo ceramic tile yekunamira.
