Zvinonamira zvemataira zvinowanzo shandiswa muindasitiri yekuvaka kugadzira chisungo chakasimba uye chinogara kwenguva refu pakati pemataira nemidziyo. Zvisinei, kuwana chisungo chakachengeteka uye chinogara kwenguva refu pakati pemataira nemidziyo kunogona kuoma, kunyanya kana pamusoro pemidziyo isina kuenzana, yakasvibiswa kana kuti ine maburi.
Mumakore achangopfuura, kushandiswa kwehydroxypropyl methylcellulose (HPMC) muma tile adhesive kwave kuri kufarirwa zvakanyanya nekuda kwehunhu hwayo hwakanaka hwekunamira. HPMC ipolymer inoshanda zvakasiyana-siyana inobva mu cellulose inowanzoshandiswa se thickener, stabilizer uye suspension agent mumaindasitiri emishonga, cosmetic uye chikafu. HPMC inoshandiswawo zvakanyanya muindasitiri yekuvaka, kunyanya muma tile adhesives, sezvo viscosity yayo yakakwira inowedzera hunhu hwe bonding hwema tile.
Wedzera hunhu hwekubatanidza mataira eceramic uchishandisa HPMC ine viscosity yakakura
1. Deredza kunwa mvura
Chimwe chezvinetso zvikuru pakuwana chisungo chakasimba pakati pemataira nesubstrate inyaya yekuti substrate inonwisa mvura, zvichiita kuti namatidziro ibude uye isashande. HPMC haifariri mvura uye inobatsira kuderedza kunyudzwa kwemvura nesubstrate. Kana HPMC yawedzerwa kune namatidziro dzemataira, inoumba jira pasubstrate rinodzivirira kupinda kwemvura uye rinoderedza njodzi yekubuda kwenamatidziro.
2. Kuvandudza kushanda zvakanaka
Kuwedzera HPMC ine viscosity yakakura kune tile glue kunogona kuvandudza mashandiro ekugadzira glue. Viscosity yakakura HPMC inoshanda semukobvu, ichipa glue magadzirirwo akatsetseka uye akafanana. Kugadzikana uku kuri nani kunoita kuti zvive nyore kuisa glue kune substrate, zvichideredza njodzi yekudonha kana kudonha uye kugadzira chisungo chakasimba pakati petile ne substrate.
3. Wedzera kunamira
Kukwidibira kwakanyanya kweHPMC kunogonawo kuwedzera kubatana kwemataira nekuvandudza hunhu hwekubatanidza kwenamira. Kukwidibira kwakanyanya kweHPMC kunogadzira zvisungo zvemakemikari zvakasimba nenamira yemataira ne substrate, zvichigadzira chisungo chakasimba uye chakavimbika. Pamusoro pezvo, hunhu hwekukora kweHPMC hunopa namira simba rakakura rekutakura mutoro, nokudaro zvichivandudza kugara kwenguva refu kwenamira.
4. Deredza kudzikira kwesimba
Kusakwana kwekunamira mataira kunogona kukonzera kupwanyika, zvichisiya mipata pakati petaira ne substrate. Zvisinei, kupenya kwakanyanya kweHPMC kunogona kubatsira kuderedza kupwanyika kwenamira yemataira nekugadzira kugadzikana kwakasimba uye kwakafanana panguva yekushandiswa. Kudzikira kwekupwanyika kunowedzera simba rekubatanidza, zvichiita kuti namira igare kwenguva refu.
5. Kuvandudza kusimba kwekuputika kwematombo
Mataira esimbi asina kubatana zvakanaka nepasi pevhu anogona kutsemuka nekutyoka. HPMC ine hunhu hwakanaka hwekudzivirira kutsemuka, zvichibatsira kudzivirira kutsemuka uye kuona kuti chinamira chesimbi chinoramba chiripo kwenguva refu. HPMC inogovera zvakaenzana kushushikana, inopa chisungo chakasimba, uye inodzivirira kutsemuka kwakamira uye kwakatwasuka.
mukupedzisa
HPMC ine viscosity yakakura inoita basa rakakosha mukusimudzira hunhu hwekubatanidza mataira, kunyanya panzvimbo dzakaoma. Kuwedzera HPMC kune tile glue kunogona kuvandudza kushanda, kuderedza kunyudzwa kwemvura, kuwedzera kunamira pakati pechinhu chepasi ne tile glue, kuderedza kupwanyika, uye kuvandudza kuramba kwe glue.
Zvakakosha kutaura kuti HPMC ine hushamwari kune nharaunda uye haina chepfu, zvichiita kuti ive sarudzo yakakodzera kumapurojekiti emataira eceramic munzvimbo dzinonyanya kukanganiswa nenharaunda. Nokudaro, kushandisa HPMC ine viscosity yakakura mumatinamiro emataira hakungogadzirisi kunaka kwenamira chete, asiwo kunokurudzira kuchengetedzeka kwenharaunda.
Indasitiri yekuvaka inogona kubatsirwa zvikuru nekushandisa HPMC ine simba rakawanda mumatiles anonamira. Ichi chigadzirwa chakachengeteka, chinoshanda, chiri nyore kushandisa chinosimbisa chisungo pakati pematiles ne substrate, zvichiita kuti chigare kwenguva refu. Nekushandisa chinhu ichi, vanhu vanogona kunakidzwa nekugara kwenguva refu, mari shoma yekugadzirisa, nyore kushandisa, uye hushamwari hwezvakatipoteredza.
