Zvigadzirwa zvepasi:
Kudzora fluidity: MHEC inogona kugadzirisa fluidity uye viscosity yezvinhu zvekuzvimiririra pasi kuti ive nechokwadi chekuti pasi rakati sandara uye rakatsetseka.
4. Kushandiswa kweMHEC mumhizha yekuputira
Pendi yemvura:
Kuomesa nekudzikamisa: Mumvura-yakavakirwa pendi, MHEC inoshanda seyakakora uye yakagadzikana kuvandudza kumiswa uye kugadzikana kwepende uye kudzivirira sedimentation yepigments uye fillers.
Kuvandudza rheology: Inogonawo kugadzirisa rheology yepende, kuvandudza brushability uye flatness.
Latex pendi:
Kuvandudza kuchengetedza kwemvura uye firimu-kugadzira zvinhu: MHEC inowedzera kuchengetedza kwemvura uye firimu-kugadzira zvinhu zvependi ye latex uye inovandudza anti-scrub performance yependi firimu.
5. Kushandiswa kweMHEC mukuchera mafuta
Drilling fluid:
Kuvandudza viscosity uye kugadzikana: Mumafuta ekuchera mvura, MHEC inovandudza viscosity uye kugadzikana kwemvura yekuchera, inobatsira kutakura zvidhiro zvekucheka, uye inodzivirira kudonha kwemadziro zvakanaka.
Deredza kurasikirwa kwekusefa: Kuchengeta kwayo mvura kunogona kuderedza kurasikirwa kwekusefa uye kudzivirira kukuvadzwa kwekuumbwa.
Mvura yekupedzisira:
Lubrication uye kuchenesa: MHEC inoshandiswa mukupedzisa fluid kuvandudza lubricity uye kuchenesa kugona kwemvura.
6. Kushandiswa kweMHEC mumhizha yezvokudya
Food thickener:
Kune zvigadzirwa zvemukaka uye zvinwiwa: MHEC inogona kushandiswa seyakakora mune zvigadzirwa zvemukaka uye zvinwiwa kuvandudza kuravira uye kugadzikana.
Stabilizer:

9. Zvakanakira nekuipira kweMHEC
Zvakanakira:
Versatility: MHEC ine mabasa akawanda akadai sekukora, kuchengetedza mvura, kumiswa, emulsification, nezvimwewo, uye ine huwandu hwakawanda hwekushandisa.
Hushamwari kwezvakatipoteredza: MHEC chinhu chinoorera chine kusvibiswa kushoma kwezvakatipoteredza.
Kugadzikana kwakasimba: Inoratidza kugadzikana kwakanaka pasi pe pH yakasiyana uye tembiricha mamiriro.
Zvakaipa:
Mutengo wepamusoro: Kana uchienzaniswa nemamwe makuhwa echinyakare, mutengo wekugadzira weMHEC wakakwira.
Kuenderana neMamwe Makemikari: Mune mamwe magadzirirwo, MHEC inogona kunge iine nyaya dzekuenderana nemamwe makemikari.
Nekuda kwehunhu hwayo hwakanaka hwemuviri nemakemikari, methyl hydroxyethyl cellulose (MHEC) inoshandiswa zvakanyanya mumaindasitiri mazhinji akadai sekuvaka, machira, peturu, chikafu, mushonga uye kugadzira mapepa. Seyakakora, inochengetedza mvura, binder uye stabilizer, inopa yakakosha kuita rutsigiro kune zvigadzirwa uye maitiro muminda dzakasiyana. Nekudaro, mumashandisirwo anoshanda, kuenderana kwayo nezvimwe zvinongedzo uye mutengo zvinhu zvinofanirwawo kutariswa. Mune ramangwana, nekufambira mberi kwehunyanzvi uye shanduko mukudiwa kwemusika, nzvimbo dzekushandisa dzeMHEC dzinogona kuwedzerwa.
