Mahwendefa echiwile anotamba chinzvimbo chakakomba muindasitiri yekuvaka, ichiratidza kusungwa kwekuchengetedza mataira kune akasiyana substrates. HydroxyPropyl methylcellose (HPMC) ndiyo kiyi inoshanda mune akawanda emazuva ano tiles inonamatira, inopa yakashongedzwa kuomerera zvinhu uye kushanda.
1.Instanting hydroxyprusyl methylcellose (HPMC):
HPMC ndeye cellulose inogamuchirwa inowanzo shandiswa mune zvekuvaka yekuzvinamatira kwayo, kutema, uye kudzokorora kwemvura.
Iyo inotorwa kubva kune yakasikwa cellulose uye yakagadziriswa kuita hupfu hwakanaka.
HPMC inosimudzira simba rekubatanidza rekusimbisa kwemagetsi zvinoshatirisa apo achivandudza kushanda kwavo uye nekuchengetwa kwemvura kuchengetwa kwemvura.
2.Formand of Hpmc-based Tile Adhesive:
a. Basic S60:
Portland cement: Inopa iyo yekutanga inosunga mumiririri.
Jecha rakanaka kana kuti filler: inosimudzira kushanda uye kuderedza shrinkage.
Mvura: Inodikanwa yeHydration uye Kubata.
Hydroxyprishpropyl methylcellose (HPMC): inoita seyakakora uye yekubatanidza mumiririri.
Kuwedzera: kunogona kusanganisira polymer modifiers, kuvaparadzira, uye anti-sag vamiririri vezvakanyanya zvekuita zvekushandisa.
b. Kuenderana:
Chikamu chega chega chinongedzo chinosiyana zvichienderana nezvinhu zvakadai semuenzaniso mhando, substrate, uye mamiriro ekunze.
Kuumbwa kwezvinhu kunogona kuve ne 20-30% simende, 50-60% jecha, 0,5-2% hpmc, uye zvakakodzera zvemvura zvemvura kuti uwane kusimba kwaunoda.
c. Kusanganisa maitiro:
Dry sanganisa simende, jecha, uye hpmc zvakakwana kuve nechokwadi chekuparadzirwa kwounifomu.
Zvishoma nezvishoma wedzera mvura uku uchisanganisa kusvikira iyo yaunoda kuwirirana kunowanikwa.
Sanganisa kusvikira pakajeka, gwai-yemahara pasita inowanikwa, ichiratidza kuti hydration yakakodzera yemasimendi zvikamu uye kupararira kweHPMC.
3.Application yeHPMC-yakavakirwa tile inonamira:
a. Kugadzirira pamusoro:
Ita shuwa kuti substrate yakachena, kurira kwakarongeka, uye kusununguka kubva kuguruva, mafuta, uye zvinosvibisa.
Nzvimbo dzakaomarara kana dzisina kufanana dzinoda kuunganidza kana priming isati yanamatira application.
b. Maitiro ekushandisa:
Trowel application: Iyo inonyanya kuzivikanwa nzira inosanganisira kushandisa yakagadziriswa trowel kuti uparadzanise chinonamatira pane substrate.
Kudzokera-butter
Spot Bonding: Inokodzera marara akaremerwa kana zvekushongedza zvinoshandiswa, zvinosanganisira kushandisa chinonamatira mumatanho madiki pane kungozviparadzira pane zvese substrate.
c. Kuisirwa tile:
Dzvanya mataira akasimba mumubhedha wekunamatira, uchisimbisa kuzere kakawanda uye kufukidzwa kwunifomu.
Shandisa spacers kuti urambe uchiramba uchienderana macompu majoini.
Rongedza tile alignment nekukurumidza isati yamira isati yamira.
d. Kuporesa uye Kugomera:
Bvumira chinonamatira kuporesa maererano nemirairo yemugadziri usati wakura.
Gruther mataira achishandisa zvinhu zvakakodzera zvegrout, kuzadza majoini akazara uye anotsemuka pamusoro.
4.Rinodaloger yeHPMC-yakavakirwa tile inonamira:
Yakavandudzwa Kubatira Simba: HpMC inovandudza kudiwa kune maviri mataira uye subsrates, kuderedza njodzi ye tiles destachment.
Kuvandudzwa Kurovedza: Kuvhapo kweHPMC kunowedzera basa rekushanda uye nguva yakavhurika yekunamatira, kubvumira kuve nyore kushandisa uye kugadzirisa mataira.
Kuchengeta kwemvura: HPMC inobatsira kuchengetedza kunyorova mukati mekunamatira, kusimudzira hydration yakakodzera yeiyo simende uye kudzivirira nguva isati yanyanyisa.
HPMC-yakavakirwa tile inonamira inopa mhinduro yakavimbika kune dzakasiyana-siyana mashopu ekurwara, achipa kusimba kwakasimba, kuvandudza kushanda, uye kuvandudza kusimba. Nokunzwisisa maitiro ekuumbwa uye nzira dzekushandisa dzakataurwa muiyi nhungamiro, nyanzvi dzekuvaka dzinogona kushanda zvinobudirira HPMC maHPMC jekisiti kuti uwane huwandu hwepamusoro-mhando tera.
