Methylhydroxyethylcellulose (MHEC) chinhu chinowanzo shandiswa mukuwedzera mune simende-based zvinhu zvakaita sedhaka nekongiri. Iyo ndeyemhuri ye cellulose ethers uye inotorwa kubva kune yakasikwa cellulose kuburikidza nemakemikari ekugadzirisa maitiro.
MHEC inonyanya kushandiswa seyakakora, inochengetedza mvura mumiriri uye rheology modifier mune simende-based zvigadzirwa. Inobatsira kuvandudza kushanda uye kuwirirana kwemasanganiswa esimende, zvichiita kuti zvive nyore kubata panguva yekuvaka. MHEC inopawo mamwe mabhenefiti akati wandei, anosanganisira:
Kuchengetwa kwemvura: MHEC ine simba rekuchengetedza mvura, iyo inodzivirira kuoma kusati kwasvika kwezvinhu zvakagadzirirwa simenti. Izvi zvinonyanya kukosha munzvimbo dzinopisa, dzakaoma kana kuti nguva yekushanda yakawedzerwa inodiwa.
Yakavandudzwa Kunamatira: MHEC inosimudzira kunamatira pakati pesimende zvinhu uye mamwe ma substrates akadai sezvidhinha, dombo kana tile. Inobatsira kuvandudza simba rezvisungo uye inoderedza mukana we delamination kana kupatsanurwa.
Yakawedzerwa Nguva Yakavhurika: Nguva yekuvhura ndiyo nguva yenguva iyo dhaka kana yekunamatira inoramba ichishandiswa mushure mekuvaka. MHEC inobvumira nguva yakareba yakazaruka, ichibvumira nguva yakareba yekushanda uye kugadzirisa zviri nani zvinhu zvisati zvasimba.
Enhanced Sag Resistance: Sag resistance inoreva kugona kwechinhu kuramba kudonha kwakamira kana kudonha kana kwaiswa panzvimbo yakatwasuka. MHEC inogona kuvandudza sag kuramba kwesimende-yakavakirwa zvigadzirwa, kuve nechokwadi chekunamatira kuri nani uye kuderedza deformation.
Kuvandudzwa kwekushanda: MHEC inoshandura rheology ye-cement-based materials, inovandudza kuyerera kwavo uye kupararira. Inobatsira kuwana musanganiswa wakapfava uye unowirirana, zvichiita kuti zvive nyore kubata nekushandisa.
Kudzora Kugadzirisa Nguva: MHEC inogona kupesvedzera nguva yekumisikidza simenti-yakavakirwa zvinhu, zvichibvumira hukuru hwekutonga pamusoro pekurapa maitiro. Izvi zvinonyanya kubatsira mumamiriro ezvinhu apo nguva yakareba kana ipfupi yekuseta inodiwa.
Izvo zvinofanirwa kucherechedzwa kuti iyo chaiyo zvivakwa uye kuita kweMHEC kunogona kusiyana zvichienderana neiyo molecular uremu, dhigirii rekutsiva, uye zvimwe zvinhu. Vagadziri vakasiyana vanogona kupa MHEC zvigadzirwa zvine maitiro akasiyana kuti zvienderane nemashandisirwo chaiwo.
Pakazere, MHEC inowedzerwa yakawanda-inoshanda iyo inogona kusimudzira mashandiro uye kugadziridzwa kwesimende-yakavakirwa zvinhu, ichipa mabhenefiti akadai sekuvandudza adhesion, kuchengetwa kwemvura, sag kuramba uye inodzorwa kuseta nguva.
