Hydroxypropyl methylcellulose (HPMC) ikemikari yakagadziridzwa cellulose inoshandiswa zvakanyanya muindasitiri yekuvaka nekuda kwezvivakwa zvayo zvakanaka.
1. Basic performance overview
HPMC isiri muchetura, isinganhuhwi, nonionic cellulose ether ine mvura yakanaka kunyungudika uye kunamira. Zvinhu zvayo zvikuru zvinosanganisira:
Kukora: Inogona kuwedzera zvakanyanya viscosity yemhinduro uye kuvandudza rheological maitiro ezvivakwa zvekuvaka.
Kuchengetwa kwemvura: Iine yakanakisa kuchengetedza mvura uye inogona kuderedza kurasikirwa kwemvura.
Adhesion: Wedzera kunamatira pakati pezvivakwa zvekuvaka uye substrates.
Lubricity: Inovandudza kutsetseka uye nyore kushanda panguva yekuvaka.
Kuramba kwemamiriro ekunze: kushanda kwakadzikama pasi pepamusoro kana pasi pemamiriro ekushisa.
2. Zvikumbiro zvakananga muindasitiri yekuvaka
2.1. Cement dhaka
Mudhaka resimende, HPMC inonyanya kushandiswa sechinhu chinochengeta mvura uye chikobvu. Inogona kudzivirira zvinobudirira dhaka kubva pakutsemuka uye kurasikirwa kwesimba nekuda kwekukurumidza kubuda kwemvura, uye panguva imwechete inovandudza mashandiro ekuvaka uye anti-sagging kugona. Doka rine simba rekuchengetedza mvura rinonyanya kukodzera kuvakwa munzvimbo yakakwirira yekupisa uye yakaderera humidity environments.
2.2. Tile adhesive
Tile inonamira inoda yakakwira chisungo simba uye kureruka kwekuvaka, uye HPMC inoita basa rakakosha mune izvi. Kune rumwe rutivi, inovandudza hukama hwekubatana kuburikidza nekukora uye kuchengetedza mvura; kune rumwe rutivi, inowedzera nguva yekuvhura kufambisa vashandi kugadzirisa nzvimbo yekeramic tile kwenguva yakareba.
2.3. Putty powder
Sechidziro chekuyera madziro, kuita kwekuvaka uye kupera kwechigadzirwa mhando yeputty poda zvine hukama nebasa reHPMC. HPMC inogona kuvandudza kutsetseka uye kuchengetwa kwemvura kweputty poda, kudzivirira kutsemuka kwemadziro uye upfu, uye kugadzirisa kusimba uye aesthetics yechigadzirwa chakapedzwa.
2.4. Gypsum-based products
Mune gypsum-based self-leveling uye caulking gypsum, HPMC inopa yakanakisa kukora uye kuchengetedza mvura zvivakwa, inovandudza shrinkage kuramba uye kushanda kwekuvaka kwezvigadzirwa zvegypsum, uye inodzivirira kupaza uye kusakwana simba rinokonzerwa nekurasikirwa kwemvura yakawandisa.
2.5. Kuvhara kwemvura
HPMC inogona kushandiswa seyakakora uye inodzikamisa yekuputira isina mvura, ichipa iyo coating iri nani rheology uye firimu-kugadzira zvivakwa kuti ive nechokwadi chekufanana uye kunamatira kweiyo coating.
2.6. Pfaya plaster uye pfapfaidza dhaka
Mumichina yekupfapfaidza, HPMC inopa yakanaka fluidity uye kupomba kuita, uku ichidzikisa sag uye delamination zviitiko, kuvandudza kugona uye kunaka kwekupfapfaidza kuvaka.
2.7. Exterior wall insulation system
Mukunze kwemadziro ekudzivirira masisitimu, kuchengetwa kwemvura uye anti-kutsvedza zvivakwa zveHPMC zvinoita basa rakakosha mukubatanidza uye kupurasita madhaka. Inogona kuvandudza zvakanyanya kuita kwekuvaka kwedhaka uye kuve nechokwadi kugadzikana uye kusimba kweiyo insulation system.
3. Zvakanakira zveHPMC muindasitiri yekuvaka
Kuvandudzwa kwekuita kwekuvaka: Kuwedzerwa kweHPMC kunoita kuti zvinhu zvekuvaka zvishande, maitiro ekuvaka ari munyoro, uye marara emidziyo uye kuoma kwekuvaka kunoderedzwa.
Deredza matambudziko emhando: Mushure mekuchengetwa kwemvura uye kunamatira kwavandudzwa, zvinhu zvacho zvichava nezvinetso zvishoma sekuputika uye delamination, kuvandudza kunaka kwechigadzirwa chakapedzwa.
Kuchengetedza magetsi uye kuchengetedzwa kwezvakatipoteredza: Kushanda kwakanyanya kweHPMC kunokwidziridza kuita kwezvinhu, kunoderedza tsvina yezviwanikwa kunokonzerwa nekuvakwa kwakadzokororwa, uye kune mhedzisiro yakanaka pakuchengetedza simba uye kuchengetedza kwezvakatipoteredza.
Kudzora kwemitengo: Nekuvandudza kushanda kwezvinhu, mutengo wekugadzirisa gare gare uye kutsiva unoderedzwa, zvichiita kuti ive yakanyanya hupfumi.
4. Mafambiro ebudiriro yeramangwana
Sezvo kudiwa kweindasitiri yekuvaka kwepamusoro-kuita uye zvakasvibira zvine hushamwari zvinhu zvichiwedzera, kugona kweHPMC mukugadzirisa uye kuumbwa kwekushandisa kuchiri kuongororwa. Semuyenzaniso, kusanganisa HPMC nemamwe magadzirirwo emakemikari kugadzira akakosha mafomula emhando dzakasiyana dzemashandisirwo igwara rakakosha rekusimudzira mune ramangwana. Pamusoro pezvo, kuenderera mberi nekuvandudza kugadzikana kwekuita kwayo uye kugona kwekugadzira kuburikidza nekugadzirisa maitiro ndiko zvakare kutariswa kwekutsvaga kwemaindasitiri.
Hydroxypropyl methylcellulose inoita basa rakakosha muindasitiri yekuvaka nekuda kwehunhu hwayo hwakanaka. Kubva kudhaka resimende kusvika kune inonamira mataira, kubva putty poda kusvika pakuputira mvura, kushandiswa kweHPMC kunovhara zvese zvezvinhu zvekuvaka. Mune ramangwana, nekufambira mberi kwetekinoroji uye nekushandisa kwakadzama, HPMC ichaita basa rakakosha mukubatsira indasitiri yekuvaka kuwana mashandiro epamusoro, kushandiswa kwesimba shoma uye zvinangwa zvekuchengetedza zvakasvibirira kwezvakatipoteredza.
