HPMC, ine zita rakazara reHydroxypropyl Methylcellulose, ndeye multifunctional chemical additive inowanzoshandiswa mukuvaka zvinhu. Mukuisa mataira eceramic, HPMC inoita basa rakakosha uye inonyanya kushandiswa mumatairi anonamira, putty poda, uye mamwe madhaka ekuvaka kuvandudza kushanda kwezvinhu uye nyore kuvaka.
1.Basic zvinhu zveHPMC
HPMC is a cellulose ether yakagadzirwa nekemikari yakagadziridzwa selulosi chaiyo. Iine zvinotevera zvakakosha zvimiro:
Kukora: HPMC inokwanisa kuwedzera zvakanyanya viscosity yemvura kana pasty zvinhu, izvo zvakakosha kune anonamira mataira uye dhaka. Iyo yakakora zvinhu ine kunamatira kuri nani uye inogona kudzivirira nemazvo matiles kubva pakutsvedza panguva yekuisa.
Kuchengeta Mvura: HPMC inochengetedza mvura mune simende-yakavakirwa zvinhu, ichiwedzera nguva yakavhurika yedhaka rako kana mataira anonamira. Izvi zvinoreva kuti vashandi vane nguva yakawanda yekugadzirisa kana vachiisa mataira, uye zvinobatsirawo simenti kuti inyatso hydrate, ichivandudza chisungo chekupedzisira.
Lubricity: HPMC inoita kuti dhaka riwedzere kunyorova uye rishande, richideredza kupokana panguva yekuvaka uye kubvumira vashandi kuisa mataira zviri nyore.
Adhesion: HPMC inopa yakanaka adhesion zvivakwa, zvichiita kuti chisungo pakati pematairi uye substrate chive chakasimba uye kuderedza njodzi yekudonha kwematiles.
2.Kushandisa mu ceramic tile kuisa
Mukugadzika mataira eceramic, HPMC inonyanya kushandiswa sechigadziriso chekunamira kwematairi nemadhaka. Kunyanya, HPMC yakaita basa rakanaka mukugadzika mataira eceramic mune zvinotevera zvinhu:
Kuvandudza kushanda kwekuvaka: HPMC inowedzera kuchengetedza kwemvura uye kushanda kwe tile glue, zvichibvumira vashandi kuti vave nenguva yakareba yekugadzirisa kana vachiisa mataira pasina kunetseka nezvekuoma kweglue nekukurumidza. Izvi zvinoderedza mukana wekugadzirisa zvakare uye inovandudza kushanda kwekuvaka.
Yakavandudzwa yekuisa mhando: Nekuvandudza kusimba kwechisungo chekunamira kwematairi, HPMC inobatsira kudzivirira matambudziko emhando sekuchera uye kudonha kubva pamatiles panguva yekuomesa. Iyo yekukora pfuma inoitawo kuti tirairi inonamira isanyanya kuyerera kana ichiisa pamafacade kana sirin'i, kuve nechokwadi kutsvinda uye kushanda kwekuvaka.
Inochinjika kune dzakasiyana siyana dzekuvaka nharaunda: Iyo yakanaka yekuchengetedza mvura inopihwa neHPMC inobvumira tile inonamira kuti ichengetedze yakagadzikana yekuvaka kuita mukupisa kwakanyanya kana nzvimbo dzakaoma, uye hazvizokonzeresa kusakwana kwekunamatira nekuda kwekukurumidza kubuda kwemvura.
3. Kuchengetedza panguva yekuvaka
Paunenge uchishandisa mataira anonamira kana dhaka rine HPMC, vashandi vanofanirwa kutarisisa kune anotevera mapoinzi:
Chiyero chinofanira kunge chakarurama: huwandu hweHPMC hunokanganisa zvakananga kushanda kwekunamatira tile. Kunyanya kana kushoma kunotungamira kune mibairo isina kunaka yekuvaka. Nokudaro, kuenzana kunofanira kunyatsoenderana nemirairo yechigadzirwa.
Sanganisa zvakanaka: Paunenge uchigadzira mataira anonamira kana dhaka, HPMC inoda kunyatsosanganiswa nezvimwe zvinhu kuti ive nechokwadi chekuti zvivakwa zvayo zvinogona kuiswa zvakaenzana. Kusanganiswa kusina kunaka kunogona kukonzera kusakwana kwekunamira kwenzvimbo kana kuomesa zvisina kuenzana.
Ramba wakachena: Panguva yekuisa mataira eceramic, maturusi ekuvaka uye zvakatipoteredza zvinofanirwa kuchengetedzwa zvakachena kudzivirira kusvibiswa kusanganisirwa nekukanganisa hukama.
Sekuwedzera kwekuvaka kwakanaka, HPMC inoita basa risingadzoreki mukugadzika mataira eceramic. Haisi kungovandudza kushanda kwematairi ekunamatira uye madhaka, asiwo inovandudza kushanda kwekuvaka uye yekupedzisira mhando. Naizvozvo, HPMC chinhu chakakosha uye chinoshandiswa zvakanyanya mukuvaka zvivakwa zvemazuva ano.
