Hydroxypropyl methylcellulose (HPMC)chinhu chinoshandiswa zvakanyanya mukugadzira, mishonga, chikafu uye makemikari ezuva nezuva. Muzvinhu zvekuvaka, kunyanya muma tile adhesives, wall putty, dry mortars, nezvimwewo, HPMC, sechinhu chakakosha chekuwedzera, haingogadzirise mashandiro ekuvaka chete, asiwo ine simba guru pakuita kwekubatana.
1. Hunhu hwekutanga hweHPMC
AnxinCel®HPMC chinhu chinobva mu cellulose chine mvura inonyunguduka zvakanaka, inonamira uye inokora. Chinoumba colloid mumvura kuburikidza ne hydroxypropyl ne methyl groups muchimiro chayo chemamorekuru, izvo zvinogona kuvandudza kunamira, rheology uye kuchengetedza mvura kwechinhu chacho. Mukuvaka manamira, kuwedzerwa kweHPMC kunogona kuvandudza simba remanamira, kuwedzera nguva yekuvhurika, uye kuvandudza kupararira uye kuramba mvura. Nokudaro, huwandu hweHPMC hune chekuita zvakananga nekushanda kwehunhu uhwu, izvo zvinokanganisa mhedzisiro yemanamira.
2. Mhedzisiro yemuyero weHPMC pasimba rekubatana
Simba rekubatanidza ndiro chiratidzo chikuru chekuongorora mashandiro ezvinonamatira zvekuvaka. Huwandu hweHPMC hunowedzerwa kune chinonamatira hunogona kukanganisa zvakanyanya simba rekubatanidza. Kune rumwe rutivi, huwandu hwakakodzera hweHPMC hunogona kuwedzera kubatana uye simba rezvinhu zvakagadzirwa nesimende. Izvi zvinodaro nekuti HPMC inovandudza kuchengetedza mvura mudhaka, zvichibvumira simende kuti iite zviri nani nepamusoro pe substrate panguva yekuoma, nokudaro ichivandudza mhedzisiro yekupedzisira yekubatanidza. Kune rumwe rutivi, kana huwandu hweHPMC huri hudiki, kuchengetedza kwayo mvura hakuna kukwana, izvo zvinogona kukonzera kuti simende irasikirwe nemvura nguva isati yakwana, zvichikanganisa maitiro ekuoma uye zvichikonzera simba rekubatanidza risina kugadzikana; nepo kana huwandu hwacho hwakanyanya, zvinogona kukonzera kuti chinonamatira chive chakanyanya kusimba, zvichikanganisa mashandiro ekuvaka uye zvichitokonzera kudzikira kwesimba.
Ongororo dzakaratidza kuti huwandu hwakakodzera hweHPMC hunowanzova pakati pe0.5% ne2%, izvo zvinogona kuvandudza simba rekubatanidza mukati merudzi urwu uku zvichivimbisa zvimwe zvinhu zvakaita sekuyerera uye kushanda zvakanaka. Zvisinei, huwandu hwacho hunofanirwa kugadziriswa zvichienderana nerudzi rwe substrate nenzvimbo chaiyo yekushandisa.
3. Mhedzisiro yemuyero weHPMC pakushanda kwekuvaka
Kushanda kwekuvaka chimwe chezviratidzo zvakakosha zvekuongorora manamati, kunyanya kusanganisira kuyerera, nyore kwekuvakwa uye nguva yekushanda inogadziriswa. Huwandu hweHPMC hune mhedzisiro yakakura pahunhu uhwu. Sezvo huwandu hweHPMC huchiwedzera, viscosity yemanamati inowedzerawo, ichiratidza kunamira kwakasimba uye nguva yakareba yekuvhurwa. Kunyangwe nguva refu yekuvhurwa dzimwe nguva ichigona kuvandudza kuchinjika kwekuvakwa, inogonawo kukonzera kuti pamusoro pechivakwa panamatire uye kukanganisa mhedzisiro yekubatana.
Kune mhando dzakasiyana dzezvinhu zvakaita semataira, matombo, madziro, nezvimwewo, huwandu hweAnxinCel®HPMC hunofanira kugadziriswa. Semuenzaniso, kana nguva yakareba yekushanda nekugadzirisa ichifanira kudiwa, kuwedzera huwandu hweHPMC zvakakodzera kunogona kuwedzera nguva yekuvhura uye kudzivirira kuoma nekukurumidza, zvichikonzera kusasimba kwekubatana. Zvisinei, kana nguva yekuvhura yakareba zvakanyanya, zvinogona kukonzera kutsvedza kusingakoshi panguva yekuvaka uye kukanganisa kururama kwekuvaka.
4. Mhedzisiro yemuyero weHPMC pakudzivirira mvura uye kudzivirira mamiriro ekunze
HPMC haingogone chete kuvandudza simba rekubatanidza uye mashandiro ekuvaka, asiwo inovandudza kuramba kwemvura uye kuramba kweglue. HPMC inovandudza kuchengetedza mvura kwesimende, kuitira kuti gundi rakagadzirwa nesimende risarasikirwa nemvura nekukurumidza panguva yekuoma, nokudaro richiwedzera kuramba kwayo mvura uye kuramba kwemamiriro ekunze. Kana chiyero cheHPMC chakakodzera, kuramba kwemvura uye hupenyu hwebasa rechinhu chacho zvinogona kuvandudzwa zvakanyanya, kunyanya mumadziro ekunze nenzvimbo dzine hunyoro, uko kuramba kwemvura kwesimende kwakakosha.
Zvisinei, HPMC yakawandisa inogona kukonzera kukora kwakanyanya kwenamira, kukanganisa kugadzikana kwechimiro chezvinhu zvakagadzirwa nesimende, uye kuderedza kuramba kwayo mvura. Nokudaro, kugadzirisa chiyero cheHPMC kuti ienzanise kunyorova uye kuramba simende mvura ndicho chinhu chikuru chekuona kuti kubatana kwacho kunoshanda.
5. Mhedzisiro yemuyero weHPMC pane zvimwe zvinhu zvemuviri
Pamusoro pekusimba kwekubatana, mashandiro ekuvaka, kuramba mvura, nezvimwewo, chiyero cheHPMC chinokanganisawo zvimwe zvinhu zvemuviri zveglue. Semuenzaniso, nekuwedzera kwechiyero cheHPMC, kugadzikana kweglue kunogona kuvandudzwa nekuti HPMC inogona kudzivirira kudonha kwesedimentation uye kupatsanurwa kweglue muglue uye kuchengetedza hunhu hwakaenzana hwemuviri. Pamusoro pezvo, chiyero cheHPMCine chekuitawo nezvinhu zvakaita seruvara, hunhu hwekudzivirira kutsvedza, uye nguva yekupora kwechinamira. Mhando dzakasiyana dzeHPMC dzinogona kuita basa rakanaka pasi pezvinodiwa zvakasiyana zvekuvaka.
Sechinowedzerwa chakakosha chezvinonamira zvekuvaka, AnxinCel®HPMC ine simba guru pamhedzisiro yekubatanidza. Chiyero chayo chinofanira kugadziriswa zvichienderana nezvinodiwa zvekuvaka, hunhu hwesubstrate nemamiriro ekunze. Huwandu hwakakodzera hweHPMC hunogona kuvandudza simba rekubatanidza, mashandiro ekuvaka, kuramba mvura uye kuramba mamiriro ekunze, ukuwo huchichengetedza kugadzikana kwakanaka kwemuviri. Zvisinei, HPMC yakawandisa kana kusakwana kwayo kunogona kutungamira kune hunhu hwekunamira husina kugadzikana uye kukanganisa mhedzisiro yekubatanidza. Nokudaro, mukushandiswa kunoshanda, zvakakosha kuona chiyero chakakodzera cheHPMC kuburikidza nekuyedza nekugadzirisa kuti uwane mhedzisiro yakanaka yekubatanidza.
