Redispersible latex poda (RDP) chinhu chakakosha chekuvaka chinowedzera chinoshandiswa zvakanyanya mumatairi anonamira. Haisi kungovandudza zvakasiyana-siyana zvematairi ekunamatira, asiwo inogadzirisa zvimwe zvikanganiso zvechinyakare chekubatanidza zvinhu.
1. Wedzera kunamatira
Rimwe remabasa makuru eredispersible latex poda ndeyekuvandudza kusimba kwekubatanidza kwetairi adhesives. Chinyakare simende-based adhesives inoumba chigadzirwa chakaomeswa mushure me hydration, ichipa imwe simba rekubatanidza. Nekudaro, kuomarara kwezvinhu izvi zvakaomeswa zvinomisa kunamatira. Redispersible latex powder inoparadzirwa mumvura kuti iite latex particles, iyo inozadza pores uye kuputika kwesimende-based materials uye inogadzira firimu rinoramba richinamatira. Iyi firimu haisi kungowedzera nzvimbo yekubatana, asiwo inopa adhesive imwe dhigirii yekushanduka, nekudaro inovandudza zvakanyanya simba rekubatanidza. Kuvandudzwa uku kunonyanya kukosha mukuisa mataira eceramic uko kunodiwa simba rebhondi.
2. Kuvandudza kushanduka uye kusagadzikana kwekuputika
Redispersible latex poda inogona kupa mataira anonamira zviri nani kuchinjika uye kutsemuka kuramba. Mune zvinonamatira, kuvapo kweRDP kunoita kuti yakaomeswa adhesive layer ine imwe elasticity, kuitira kuti igone kumira kudiki deformation kunokonzerwa nekushanduka kwekushisa, substrate deformation kana kushushikana kwekunze. Kuita kwakagadziridzwa uku kunoderedza njodzi yekutsemuka kana kudonhedza, kunyanya mumatairi mahombe ekushandisa kana panoiswa matiles munzvimbo dzakanyanya kushushikana.
3. Kuvandudza kudzivirira kwemvura
Kupokana kwemvura kunokosha pakushanda kwenguva refu kwematairi adhesives. Redispersible latex poda zvinobudirira kuvhara kupinda kwemvura nekugadzira dense polymer network. Izvi hazvisi kungovandudza kudzivirira kwemvura kweadhesive, asiwo inovandudza kukwanisa kwayo kutsungirira kutonhora-kunyunguduka kutenderera, zvichiita kuti tile inonamatira kuchengetedza kunamatira kwakanaka uye kugadzikana kwemaitiro munzvimbo dzine hunyoro.
4. Kuvandudza kuvaka uye maawa ekuzarura
Redispersible latex poda inogona zvakare kuvandudza mashandiro ekuvaka ematairi anonamira. Anonamira akawedzerwa neRDP ane lubricity ari nani uye kushanda, zvichiita kuti kuvaka kuve nyore. Panguva imwecheteyo, inowedzerawo nguva yakazaruka yekunamatira (kureva, nguva inobudirira iyo yakanamatira inogona kunamatira kune tile mushure mekushandisa). Izvi zvinopa vashandi vekuvaka nguva yakawanda yekushanda, zvichibatsira kuvandudza kushanda kwekuvaka uye kunaka.
5. Kuvandudza kupikisa kwemamiriro ekunze uye kusimba
Kuramba kwemamiriro ekunze uye kusimba zvinhu zvakakosha zvinopesvedzera kushanda kwenguva refu kwematairi anonamira. Iwo mapolymer particles muRDP cross-link panguva yekurapa maitiro ekunamira, achigadzira yakanyanya kugadzikana polymer network. Iyi network inogona kurwisa zvinobudirira pesvedzero yezvakatipoteredza zvinhu senge ultraviolet mwaranzi, kuchembera kwemafuta, asidhi uye alkali kukukurwa, nekudaro ichivandudza kumira kwemamiriro ekunze uye kusimba kweiyo inonamira mataira uye kuwedzera hupenyu hwayo hwebasa.
6. Deredza kunyura kwemvura uye uvandudze kurwisa ukuru
Redispersible latex poda inogona zvakare kuderedza kunyudzwa kwemvura kweanonamatira mataira, nekudaro ichidzikisa bonding layer kutadza kunokonzerwa nekuwedzera kwehygroscopic. Uye zvakare, iyo hydrophobic polymer chikamu cheRDP inogona kutadzisa kukura kwe mold uye mamwe ma microorganisms, nekudaro ichivandudza huturu-resistant zvimiro zvemataira anonamatira. Izvi zvinonyanya kukosha munzvimbo dzakanyorova kana dzepamusoro-soro, senge dzimba dzekugezera uye makicheni.
7. Chinja kune zvakasiyana-siyana zve substrates
Redispersible latex poda inopa iyo tile inonamira yakanaka yakawanda-substrate kuchinjika. Kunyangwe iri yakatsetseka vitrified mataira, mataira eceramic ane kunyudzwa kwemvura yakakwira, kana mamwe ma substrates senge simende board, gypsum board, nezvimwewo, anonamira akawedzerwa neRDP anogona kupa yakanakisa yekubatanidza zvivakwa. Izvi zvinobvumira kushandiswa kwakasiyana-siyana pakati pemhando dzakasiyana dzemataira uye substrates.
8. Kuchengetedzwa kwezvakatipoteredza
Zvinhu zvekuvaka zvemazuva ano zvinowedzera kusimbisa kuchengetedza kwezvakatipoteredza. Redispersible latex poda inowanzogadzirwa nezvinhu zvakatipoteredza zvakadai se polyvinyl doro uye acrylate. Iyo haina zvinokuvadza zvinonyungudutsa uye zvinorema simbi uye inosangana nezvinodiwa zvegirinhi zvekuvaka. Uye zvakare, RDP haiburitse volatile organic compounds (VOC) panguva yekuvaka, ichideredza kukuvadza kune vashandi vekuvaka uye nharaunda.
Iko kushandiswa kwe redispersible latex poda mumatairi e ceramic adhesives inovandudza zvakanyanya kuita kwese kweadhesive, kusanganisira kunamatira, kuchinjika, kudzivirira kwemvura, kuvaka, kuramba kwemamiriro ekunze, mildew kuramba uye kuchengetedza kwezvakatipoteredza. Izvi zvinovandudza kwete kungovandudza kushanda kwekuvaka uye kubudirira, asiwo kuwedzera hupenyu hwebasa rematairi ekunamatira, zvichivabvumira kuenderana nehupamhi hwemashandisirwo emashandisirwo. Naizvozvo, RDP inotora chinzvimbo chakakosha mune yemazuva ano ceramic tile inonamira maumbirwo, ichipa rutsigiro rwakasimba rwekuvandudza kunaka kwemapurojekiti ekuvaka.
