Mataira anonamira anowanzoshandiswa muindasitiri yekuvaka kugadzira chisungo chakasimba uye chinogara kwenguva refu pakati pematairi nema substrates.Nekudaro, kuwana chisungo chakachengeteka uye chinogara kwenguva refu pakati pematairi nema substrates zvinogona kunetsa, kunyanya kana iyo substrate nzvimbo isina kuenzana, yakasvibiswa kana porous.
Mumakore achangopfuura, kushandiswa kwehydroxypropyl methylcellulose (HPMC) mumatairi anonamira kwave kuwedzera kukurumbira nekuda kwekunamira kwayo kwakanakisa.HPMC i polymer inoshanda yakawanda inotorwa kubva ku cellulose inowanzoshandiswa seyakakora, stabilizer uye inomisa mumiriri mumaindasitiri emishonga, zvekuzora uye zvekudya.HPMC inoshandiswawo zvakanyanya muindasitiri yekuvaka, kunyanya mumatairi anonamira, sezvo yakakwira viscosity inosimudzira kusungirira zvivakwa zvematairi.
Wedzera ceramic tile bonding zvivakwa uchishandisa yakakwirira-viscosity HPMC
1. Deredza kubatwa kwemvura
Imwe yematambudziko akakosha mukuwana chisungo chakasimba pakati pe tile uye substrate ndiyo substrate inonwisa mvura, zvichiita kuti adhesive iite debond uye kukundikana.HPMC is hydrophobic uye inobatsira kuderedza kutorwa kwemvura ne substrate.Kana HPMC yawedzerwa kune mataira adhesives, inoumba dhizaini pane substrate inodzivirira kupinda kwemvura uye inoderedza njodzi yedebonding.
2. Kuvandudza kushanda
Kuwedzera yakakwirira-viscosity HPMC kune mataira adhesive inogona kuvandudza zvakanyanya mashandiro ekuvaka kweanonamira.High viscosity HPMC inoita seyakakora, ichipa kunamira kutsetseka uye kunoenderana magadzirirwo.Izvi zvakagadziridzwa kuenderana kunoita kuti zvive nyore kuisa anonamatira kune substrate, kuderedza njodzi yekudonha kana kudonha uye kugadzira chisungo chakasimba pakati petairi ne substrate.
3. Kuwedzera kunamatira
Yakakwira viscosity HPMC inogona zvakare kukwidziridza tile bonding nekuvandudza iyo yekubatanidza zvivakwa zveadhesive.High-viscosity HPMC inoumba yakasimba chemikemikari zvisungo neadhesive tile uye substrate, inogadzira chisungo chakasimba uye chakavimbika.Pamusoro pezvo, kukora zvivakwa zveHPMC zvinopa iyo inonamira nehukuru hwekutakura mutoro, nekudaro ichivandudza kusimba kwechisungo.
4. Deredza kupera
Kusakwana kwetairi kunamatira kunogona kukonzera shrinkage, ichisiya mikaha pakati petare uye substrate.Nekudaro, yakakwira viscosity HPMC inogona kubatsira kudzikisa shrinkage yekunamatira mataira nekugadzira yakagadzikana uye inowirirana kuenderana panguva yekushandisa.Yakaderedzwa shrinkage inowedzera kusimba kwechisungo, kuve nechokwadi chekugara kwenguva refu yekunamatira.
5. Kuvandudza kupesana nekutsemuka
Ceramic mataira ayo asina kusungwa zvisina kunaka kune substrate anowanzo kuputika nekupwanya.Yakakwira viscosity HPMC ine yakanakisa anti-kuparuka zvivakwa, inobatsira kudzivirira kutsemuka uye kuve nechokwadi chehupenyu hurefu hwekunamira mataira.HPMC inogovera zvakaenzanirana kushushikana, inopa chisungo chakasimba, uye inopikisa yakatwasuka uye yakachinjika kutsemuka.
mukupedzisa
Yakakwira viscosity HPMC inoita basa rakakosha mukunatsiridza mataira bonding zvivakwa, kunyanya pane inonetsa.Kuwedzera HPMC kune mataira anonamira kunogona kuvandudza kushanda, kuderedza kunyura kwemvura, kuwedzera kunamatira pakati peiyo base zvinhu uye tile inonamira, kuderedza shrinkage, uye kunatsiridza kuputika kweanonamatira.
Zvakakodzera kutaura kuti HPMC ine hushamwari kwezvakatipoteredza uye haina chepfu, zvichiita kuti ive sarudzo yakanaka yemapurojekiti ematairi eceramic munzvimbo dzinokanganisa nharaunda.Nokudaro, kushandisa high-viscosity HPMC mumatairi anonamatira kwete chete kunatsiridza kunaka kwekunamatira, asiwo kunokurudzira kuchengetedza kwezvakatipoteredza uye kuchengeteka.
Indasitiri yekuvaka inogona kubatsirwa zvakanyanya nekushandiswa kwepamusoro-viscosity HPMC mumatairi adhesives.Icho chinhu chakachengeteka, chinoshanda, chiri nyore-kushandisa chigadzirwa chinosimbisa chisungo pakati pemataira uye substrate, inova nechokwadi chekugara kwenguva refu.Nekushandisa chinyorwa ichi, vanhu vanogona kunakidzwa nekuwedzera kusimba, kuderera kwemitengo yekugadzirisa, nyore kushandisa, uye hushamwari hwezvakatipoteredza.
