Methylhydroxyethylcellulose (MHEC) is cellulose ether inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, kusanganisira yekuvaka nekuvaka.Muzvipfeko zvekugadzira, MHEC inokosha yakakora iyo inopa zvivakwa zvakananga kune iyo yekupfekedza, nekudaro ichiwedzera kushanda kwayo.
Nhanganyaya yeMethyl Hydroxyethyl Cellulose (MHEC)
MHEC isiri-ionic cellulose ether inowanikwa kubva kune zvakasikwa polymer cellulose kuburikidza neakatevedzana emakemikari ekugadzirisa.Iyo inoratidzirwa neyakasiyana musanganiswa wemethyl uye hydroxyethyl mapoka akabatanidzwa kune ayo cellulose musana.Ichi chimiro chemolecular chinopa MHEC yakanakisa kuchengetedza kwemvura, kukora uye kudzikamisa zvivakwa, zvichiita kuti ive yakakodzera kune dzakasiyana siyana dzekushandisa muindasitiri yekuvaka.
Zvimiro zveMHEC
1. Rheological properties
MHEC inozivikanwa nekunaka kwayo rheological zvimiro, ichipa yakanakira viscosity uye kuyerera maitiro ekupfeka.Iko kukora mhedzisiro kwakakosha kudzivirira kudonha uye kudonha panguva yekushandiswa uye kuve nechokwadi chekupfeka uye kwakatsetseka.
2. Kuchengeta mvura
Chimwe chezvakakosha hunhu hweMHEC kugona kwayo kuchengetedza mvura.Izvi zvinonyanya kukosha kune zvivakwa zvekuvaka sezvo zvichibatsira kuwedzera nguva yakavhurika yepende, zvichibvumira kuenzana kuri nani uye kuderedza mukana wekuoma nguva isati yakwana.
3. Kuvandudza kunamatira
MHEC inosimudzira kunamatira nekuvandudza kunyorova kwepamusoro, kuve nechokwadi chekubatana kuri nani pakati pekupfeka uye substrate.Izvi zvinovandudza adhesion, durability uye yakazara coating performance.
4. Kugadzikana
MHEC inopa kugadzikana kumucheka, kudzivirira nyaya dzakadai sekugadzirisa uye kuparadzaniswa kwechikamu.Izvi zvinovimbisa kuti iyo yekupfekedza inochengetedza kufanana kwayo muhupenyu hwesherufu uye panguva yekushandiswa.
Kushandiswa kweMHEC mune zvekuvaka machira
1. Paint uye primer
MHEC inoshandiswa zvakanyanya mukugadzirwa kwemukati nekunze pendi uye primers.Hunhu hwayo hwekukora hunobatsira kuwedzera viscosity yejasi, zvichikonzera kufukidzwa kuri nani uye nekuvandudza kushanda kweapp.Kubata kwemvura kunovimbisa kuti pende icharamba ichishandiswa kwenguva yakareba.
2. Textured coating
Mumachira akashongedzwa, MHEC inoita basa rakakosha mukuwana dhizaini yaunoda.Yayo rheological zvimiro zvinobatsira zvakaenzana kumisa pigment uye mafirita, zvichikonzera kuenderana uye kwakafanana mameseji kupera.
3. Stucco nedhaka
MHEC inoshandiswa mukugadzira stucco uye dhaka kuvandudza kushanda uye kunamatira.Zvinhu zvayo zvekuchengetedza mvura zvinobatsira kuwedzera nguva yakazaruka, zvichiita kuti zvive nani kushandisa uye kupedza zvinhu.
4. Sealants uye Caulks
Zvipfeko zvekuvaka senge sealants uye caulk inobatsira kubva mukukora zvivakwa zveMHEC.Inobatsira kudzora kuenderana kwezvigadziriso izvi, kuve nechokwadi chekuisa chisimbiso uye kusungirirwa.
MHEC Zvakanakira muArchitectural Coatings
1. Kusachinja-chinja uye kubatana
Kushandiswa kweMHEC kunovimbisa kuti mabhanhire ekugadzira anochengetedza kuwirirana uye kunyange viscosity, nokudaro kukurudzira kunyange kushandiswa uye kuvhara.
2. Wedzera maawa ekuvhura
Izvo zvinochengetedza mvura zveMHEC zvinowedzera nguva yakazaruka yepende, zvichipa vanyori nevashandisi nguva yakawanda yekushandiswa kwakanyatso.
3. Kuvandudza kushanda
Mune stucco, dhaka uye mamwe machira ekuvaka, MHEC inovandudza mashandiro ekushandisa, zvichiita kuti zvive nyore kune vanonyorera kuti vakwanise kupedzisa kwavanoda.
4. Kuwedzerwa kusimba
MHEC inobatsira kuvandudza kusimba kwese kwejasi nekuvandudza kunamatira uye kudzivirira matambudziko akadai sekudonha uye kugadzirisa.
Methylhydroxyethylcellulose (MHEC) yakakosha mukobvu mune zvekuvaka machira ane yakakosha rheology uye kuchengetedza mvura.Mhedzisiro yaro pakusagadzikana, kushanda uye kusimba kunoita kuti ive sarudzo yekutanga mukugadzirwa kwependi, maprimers, machira emucheka, stucco, dhaka, sealants uye caulk.Sezvo indasitiri yekuvaka iri kuramba ichishanduka, MHEC inoramba iri chinhu chakasiyana-siyana uye chakakosha mukuvandudza kwepamusoro-kushanda kwekuvaka machira.
