Yakajairwa viscosity maseru eHPMC mumashandisirwo ekuvaka
1 Nhanganyaya
Hydroxypropyl Methylcellulose (HPMC) chinhu chakakosha chekuvaka chinowedzera uye chinoshandiswa zvakanyanya muzvigadzirwa zvakasiyana muindasitiri yezvivakwa zvekuvaka, senge dry-mix mortar, putty powder, tile adhesive, etc. HPMC ine mabasa mazhinji akadai sekukora, kuchengetedza mvura, uye kuvandudza kushanda kwekuvaka. Kuita kwayo kunotsamira pamwero mukuru pane viscosity yayo. Ichi chinyorwa chichaongorora zvakadzama iwo akajairika viscosity siyana eHPMC mune akasiyana ekuvaka maapplication uye maitiro avo pakuita kwekuvaka.
2. Basic maitiro eHPMC
HPMC is not-ionic water-soluble cellulose ether inowanikwa nekemikari kugadziriswa kwechisikigo cellulose. Iine zvinotevera zvinozivikanwa maficha:
Kukora: HPMC inogona kuwedzera viscosity yezvinhu zvekuvaka uye inopa kushanda zvakanaka.
Kuchengetwa kwemvura: Inogona kunyatso kudzikisa kubuda kwemvura uye kugadzirisa hydration reaction inoshanda ye simenti uye gypsum.
Lubricity: Inoita kuti zvinhu zvipfave panguva yekuvaka uye kuve nyore kuisa.
Firimu-yekugadzira zvimiro: Iyo firimu yakaumbwa ine kusimba kwakanaka uye kuchinjika uye inogona kuvandudza pamusoro pezvinhu zvezvinhu.
3. Kushandiswa kweHPMC mune zvekuvaka
Tile adhesive: Basa guru reHPMC mukunamira kwetairi ndere kuvandudza simba rekubatanidza uye kuvhura nguva. Iyo viscosity range inowanzoitika pakati pe20,000 ne60,000 mPa·s kupa yakanaka yekubatanidza zvivakwa uye nguva yakavhurika. Yakakwira viscosity HPMC inobatsira kuwedzera kusimba kwechisungo chekunamatira mataira uye kuderedza kutsvedza.
Putty poda: Pakati peputty powder, HPMC inonyanya kutamba basa rekuchengetedza mvura, mafuta uye kuvandudza kushanda. Iyo viscosity inowanzova pakati pe40,000 ne100,000 mPa·s. Yepamusoro viscosity inobatsira kuchengetedza hunyoro muhupfu hweputty, inovandudza nguva yekushanda kwayo yekuvaka uye kutsetseka kwepasi.
Dry musanganiswa dhaka: HPMC inoshandiswa mune yakaoma musanganiswa dhaka kusimudzira kunamatira uye kuchengetedza mvura zvivakwa. Common viscosity ranges dziri pakati pe15,000 ne75,000 mPa·s. Mumamiriro akasiyana ekushandisa, kusarudza HPMC ine viscosity yakakodzera inogona kukwidziridza kuita kwekubatanidza uye kuchengetwa kwemvura kwedhaka.
Idhaka inozvimisa: Kuti iite kuti dhaka rinozvimisa rive nekuyerera kwakanaka uye kudzikamisa mhedzisiro, viscosity yeHPMC inowanzova pakati pe20,000 ne60,000 mPa·s. Iyi viscosity renji inovimbisa kuti dhaka rine mvura yakakwana pasina kukanganisa simba rayo mushure mekurapa.
Mvura isingapindi mvura: Mumachira asingapindi mvura, iwo viscosity yeHPMC ine simba guru pane zvekupfeka zvivakwa uye firimu-kugadzira zvinhu. HPMC ine viscosity iri pakati pe10,000 ne50,000 mPa·s inowanzo shandiswa kuve nechokwadi chekuyerera kwakanaka uye firimu-kuumba zvimiro zvejasi.
4. Kusarudzwa kweHPMC viscosity
Iyo viscosity kusarudzwa kweHPMC inonyanya kuenderana nebasa rayo mune chaiyo maapplication uye zvinodiwa zvekuvaka. Kazhinji, iyo yakakwira viscosity yeHPMC, zviri nani kukora uye kuchengetwa kwemvura, asi yakawandisa viscosity inogona kukonzera matambudziko ekuvaka. Naizvozvo, kusarudza HPMC ine viscosity yakakodzera ndiyo kiyi yekuona mhedzisiro yekuvaka.
Kukora mhedzisiro: HPMC ine yakakwira viscosity ine yakasimba thickening mhedzisiro uye inokodzera maapplication anoda yakakwirira adhesion, senge tile glue uye putty poda.
Kuita kwekuchengetedza mvura: HPMC ine viscosity yakakwirira yakanakisa mukudzora hunyoro uye inokodzera zvinhu zvinoda kuchengetedza hunyoro kwenguva yakareba, senge yakaoma-musanganiswa dhaka.
Kushanda kwekushanda: Kuti uvandudze kushanda kwechinhu, viscosity ine mwero inobatsira kuvandudza kutsetseka kwemabasa ekuvaka, kunyanya mumadhaka ekuzvimisa.
5. Zvinhu zvinokanganisa HPMC viscosity
Dhigirii repolymerization: Iyo yakakwira dhigirii yepolymerization yeHPMC, iyo yakakura viscosity. Zvishandiso zvakasiyana zvinoda kusarudzwa kweHPMC ine madhigirii akasiyana epolymerization kuti uwane mhedzisiro yakanaka.
Solution concentration: Iko kusungirirwa kweHPMC mumvura kuchakanganisawo viscosity yayo. Kazhinji kutaura, iyo yakakwira iyo yakagadziriswa mhinduro, iyo yakakura viscosity.
Tembiricha: Tembiricha ine yakakosha kukanganisa kune viscosity yeHPMC mhinduro. Kazhinji, viscosity yeHPMC mhinduro inodzikira sezvo tembiricha inowedzera.
Sekuwedzera kwakakosha muzvivakwa zvekuvaka, HPMC's viscosity inokanganisa zvakanyanya kuita kwekuvaka uye kushandisa mhedzisiro yechigadzirwa chekupedzisira. The viscosity range yeHPMC inosiyana pakati pezvishandiso, asi kazhinji iri pakati pe10,000 ne100,000 mPa·s. Paunenge uchisarudza HPMC yakakodzera, zvinodikanwa kunyatso funga nezve maitiro eviscosity pazvinhu zvenyama zvinoenderana nezvinodiwa zvekushandisa uye mamiriro ekuvaka, kuitira kuti uwane yakanakisa mhedzisiro yekushandisa.
