Kusarudza viscosity yakakodzera yeHydroxypropyl Methylcellulose (HPMC) yekugadzira putty poda yakaoma dhaka kwakakosha pakuona kuita kwakakwana uye maitiro ekushandisa echigadzirwa chekupedzisira. Iyi sarudzo inobata zvivakwa zvakati wandei, zvinosanganisira kuchengetedza mvura, kushanda, kunamatira, uye nguva yekuvhura. Heino gwara rakazara rekukubatsira iwe kunzwisisa uye kusarudza iyo chaiyo HPMC viscosity yako putty poda yakaoma dhaka kugadzira.
Kunzwisisa HPMC
Hydroxypropyl Methylcellulose (HPMC) isiri-ionic cellulose ether yakagadzirwa kubva kune yakasikwa polymer cellulose kuburikidza nehurongwa hwemakemikari maitiro. Iyo inoshanda seyakakora, binder, firimu-yaimbova, uye mumiriri wekuchengetedza mvura mune yakaoma dhaka maumbirwo.
Akakosha Mabasa eHPMC muDry Mortar
Kuchengeta Mvura: Inopa hydration yakakwana ye simende uye lime, inosimudzira kushanda uye kuderedza kutsemuka.
Kukora: Inovandudza viscosity, inobatsira pakushanda kuri nani uye kugadzikana kwedhaka.
Adhesion: Inosimudzira kusimba kwekubatanidza kwedhaka kune substrates.
Workability: Inokanganisa kusununguka kwekushandisa uye kutsetseka kwekupedzisa.
Nguva Yakazaruka: Inowedzera nguva iyo dhaka rinoramba richishanda mushure mekusanganiswa nemvura.
Zvinhu Zvokufunga nezvazvo Paunosarudza HPMC Viscosity
Zvido zvekushandisa:
Wall Putty: Inoda chiyero pakati pekushanda uye kuchengetedza mvura. Kazhinji, yepakati viscosity HPMC (50,000 kusvika 100,000 mPa.s) yakakodzera.
Tile Adhesives: Yakakwira viscosity (100,000 kusvika 200,000 mPa.s) inodiwa kuti inamatire zvirinani uye kutsvedza kuramba.
Skim Coat: Kudzika kusvika pakati viscosity (20,000 kusvika 60,000 mPa.s) yekushandisa yakatsetseka uye kupera.
Environmental Conditions:
Tembiricha uye Humidity: Yepamusoro viscosity HPMC inogona kupa nani kuchengetedza kwemvura munzvimbo inopisa uye yakaoma, kuve nechokwadi chekushanda kwenguva refu uye kuderedza kuoma kusati kwasvika.
Base Material Hunhu:
Porosity uye Absorption Rate: Kune inonyudza zvakanyanya substrates, yakakwirira viscosity HPMC inobatsira kuchengetedza unyoro kwenguva refu, kudzivirira kuoma nekukurumidza uye kuve nechokwadi chekunamira kuri nani.
Inodiwa Performance Properties:
Kushanda: Yepamusoro viscosity HPMC inopa kusimba kusimba, izvo zvinogona kuvandudza kureruka kwekupararira uye kuderedza kudonha.
Yakavhurika Nguva: Yakareba nguva yakavhurika inodiwa kune yakakura-chiyero maapplication kana inopisa mamiriro ekunze, anowanikwa nepamusoro viscosity HPMC.
Sag Resistance: Yakakwira viscosity inopa zvirinani sag kuramba, yakakosha kune yakatwasuka application.
Matanho Anoshanda Mukusarudza HPMC Viscosity
Ongorora Rudzi rweMashandisirwo:
Sarudza kana chigadzirwa chacho chiri chemadziro putty, tile adhesive, kana skim jasi.
Nzwisisa zvinodiwa chaizvo sekuchengetedza mvura, kunamatira, uye nguva yekuvhura.
Lab Testing:
Ita diki batch bvunzo neakasiyana HPMC viscosities kuona kuita.
Yera ma parameter akadai sekuchengetedza mvura, kushanda, uye kusimba kwekunamatira.
Gadzirisa Kubva pane Zvabuda:
Gadzirisai sarudzo ye viscosity zvichienderana nemhedzisiro yebvunzo.
Ita shuwa kuti chigadzirwa chekupedzisira chinosangana nezvose zvekushandisa uye kuita zvinodiwa.
Yakajairwa Viscosity Ranges yeMashandisirwo Akasiyana
Wall Putty: 50,000 kusvika 100,000 mPa.s
Mataira Adhesives: 100,000 kusvika 200,000 mPa.s
Skim Coats: 20,000 kusvika 60,000 mPa.s
Impact yeViscosity paKuita
Low Viscosity HPMC (<50,000 mPa.s): Inopa kushanda zvakanaka uye kushandiswa kwakatsetseka. Zvishoma kushanda mukuchengetedza mvura uye sag resistance. Inokodzera majasi ekupedzisira akanaka uye skim jasi. Medium Viscosity HPMC (50,000 - 100,000 mPa.s): Inoenzanisa kuchengetwa kwemvura uye kushanda. Inokodzera general wall putty application. Inosimudzira kunamatira uye kuvhura nguva zvine mwero. High Viscosity HPMC (>100,000 mPa.s):
Yakanakisa kuchengetedza mvura uye adhesion zvivakwa.
Zvirinani sag kuramba uye nguva yakazaruka.
Yakanakira mataira adhesives uye yakakwirira-performance putty magadzirirwo.
Kusarudza iyo chaiyo HPMC viscosity ye putty poda yakaoma dhaka kugadzirwa isarudzo ine mativi mazhinji inokanganisa kuita kwechigadzirwa uye kushandiswa kwayo. Nekutarisisa zvinodiwa zvekushandisa, mamiriro ezvakatipoteredza, hwaro hwezvinhu hunhu, uye zvinodiwa kuita zvivakwa, vagadziri vanogona kusarudza yakakodzera HPMC giredhi. Kuitisa kwakaringana kuyedzwa kwema lab uye kugadzirisa kunovimbisa kuti iyo yakasarudzwa viscosity inosangana nezvinodiwa chaizvo zveyakagadzirirwa application, zvichikonzera yemhando yepamusoro, yakavimbika chigadzirwa.
