Mataira anonamira anoita basa rakakosha muindastiri yekuvaka, kuve nechokwadi kusungirirwa kwakachengeteka kwemataira kune akasiyana substrates.Hydroxypropyl Methylcellulose (HPMC) chinhu chakakosha mune akawanda emazuva ano anonamira mataira, achipa inonamira zvivakwa uye kushanda kwayo.
1.Kunzwisisa Hydroxypropyl Methylcellulose (HPMC):
HPMC inotorwa selulosi inowanzoshandiswa mukuvaka zvinhu zvekunamira kwayo, kukora, uye kuchengetedza mvura.
Inotorwa kubva kune yakasikwa cellulose uye inogadziriswa kuita poda yakanaka.
HPMC inokwidziridza simba rekubatanidza remataira anonamira uku achivandudza kushanda kwavo uye maitiro ekuchengetedza mvura.
2.Kugadzira HPMC-Yakavakirwa Tile Adhesive:
a.Basic Ingredients:
Portland simende: Inopa iyo yekutanga inosunga mumiriri.
Jecha rakanaka kana kuzadza: Inosimudzira kushanda uye inoderedza kuderera.
Mvura: Inodiwa kune hydration uye kushanda.
Hydroxypropyl Methylcellulose (HPMC): Inoshanda seyakakora uye inosunga.
Zvinowedzerwa: Inogona kusanganisira mapolymer modifiers, dispersants, uye anti-sag agents kune mamwe maitiro ekuwedzera.
b.Proportioning:
Chiyero chechinhu chimwe nechimwe chinosiyana zvichienderana nezvinhu zvakaita semhando yematairi, substrate, uye mamiriro ekunze.
Iyo yakajairwa kuumbwa inogona kunge ine 20-30% simende, 50-60% jecha, 0.5-2% HPMC, uye yakakodzera mvura zvirimo kuti uwane iyo inodiwa kuenderana.
c.Kusanganisa Maitiro:
Dry sanganisa simende, jecha, uye HPMC zvakakwana kuti uve nechokwadi chekugovera yunifomu.
Zvishoma nezvishoma wedzera mvura uchisanganisa kusvikira kuwirirana kunodiwa kwaitwa.
Sanganisa kusvika pakatsetseka, isina bundu-isina paste yawanikwa, kuve nechokwadi chekuti hydration chaiyo yemasimende zvidimbu uye kupararira kweHPMC.
3.Kushandiswa kweHPMC-Based Tile Adhesive:
a.Kugadzirira Kwepamusoro:
Ita shuwa kuti substrate yakachena, yakagadzikana, uye haina guruva, girisi, uye zvinosvibisa.
Nzvimbo dzakakasharara kana dzisina kuenzana dzinogona kuda kuenzana kana kuti priming isati yanamira application.
b.Maitiro ekushandisa:
Trowel Kushandisa: Nzira yakajairika inosanganisira kushandisa trowel isina kuchekwa kuparadzira chinonamira pane substrate.
Back-buttering: Kuisa chidimbu chakaonda chekunamatira kumashure kwematairi usati waaisa mumubhedha wekunamatira kunogona kuvandudza kusungirirwa, kunyanya kune matiles makuru kana anorema.
Spot Bonding: Inokodzera matiles akareruka kana maapplication ekushongedza, anosanganisira kuisa anonamira muzvigamba zvidiki pane kuaparadzira pane yese substrate.
c.Kuisa Tile:
Dzvanya matiles zvakasimba mumubhedha wekunamatira, kuve nechokwadi chekubatana kwakakwana uye kuvhara yunifomu.
Shandisa spacers kuchengetedza majoini anoenderana grout.
Rongedza kurongeka kwetairi nekukasira pamberi pekunamatira seti.
d.Kurapa uye Grouting:
Bvumira chinonamira kurapa maererano nemirairo yemugadziri usati waita grouting.
Gadzira matiles uchishandisa yakakodzera grout zvinhu, kuzadza majoini zvachose uye kutsetseka pamusoro.
4.Advantages yeHPMC-Yakavakirwa Tile Adhesive:
Kuwedzerwa Kusimba Kusimba: HPMC inonatsiridza kunamatira kune ese matiles uye substrates, kuderedza njodzi yekumisikidza mataira.
Kuvandudzwa Kwekushanda: Kuvapo kweHPMC kunowedzera kushanda uye kuvhurika nguva yekunamatira, zvichiita kuti zvive nyore kushandisa uye kugadzirisa mataira.
Kuchengetedzwa Kwemvura: HPMC inobatsira kuchengetedza unyoro mukati mekunamira, inosimudzira hydration chaiyo yesimende uye kudzivirira kuoma nguva isati yakwana.
HPMC-based tile adhesive inopa mhinduro yakavimbika kune akasiyana mating maapplication, inopa kunamatira kwakasimba, yakagadziridzwa kushanda, uye kusimba kwakawedzera.Nekunzwisisa magadzirirwo uye nzira dzekushandisa dzakatsanangurwa mugwaro iri, nyanzvi dzekuvaka dzinogona kushandisa zvinonamira HPMC kuti dziite zvemhando yepamusoro kuisirwa mataira.
