suma:
Methylhydroxyethylcellulose (MHEC) is a versatile cellulose ether inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana nekuda kwekunaka kwekuchengetedza mvura uye inonamira zvinhu.MHEC inotorwa kubva kune yakasikwa cellulose uye yakawana zvikumbiro mukuvaka, mishonga, chikafu uye cosmetics.
Kemikari chimiro uye zvivakwa:
MHEC ndeye methyl-inotsiva hydroxyethylcellulose derivative ine yakasarudzika molecular chimiro.Iyo cellulose musana inopa inherent biodegradability uye kuenderana kwezvakatipoteredza, zvichiita kuti MHEC ive sarudzo yekutanga kune akawanda maapplication.Mapoka eHydroxyethyl uye methyl anowedzera kunyungudika kwayo uye anoshandura maitiro ayo emuviri nemakemikari, achiipa akasiyana mabasa.
Nzira yekuchengetedza mvura:
Chimwe chehukuru hunhu hweMHEC kugona kwayo kwekuchengetedza mvura.Muzvivakwa zvekuvaka zvakadai semadhaka uye simiti-based products, MHEC inoshanda semugadziri wekuchengetedza mvura, kudzivirira kurasikirwa nekukurumidza kwemvura panguva yekurapa.Izvi zvakakosha kuchengetedza kwakaringana processability, kunatsiridza kunamatira uye kuwedzera kuita kwese kwechinyorwa.
MHEC inowana kuchengetedza kwemvura kuburikidza nenzira dzinoverengeka:
Hydrophilicity: Iyo hydrophilic chimiro cheMHEC inoita kuti itore uye ichengetedze mamorekuru emvura.Iyo cellulose musana, pamwe neiyo hydroxyethyl uye methyl mapoka, inoumba chimiro chinokwanisa kuchengetedza mvura mukati me matrix ayo.
Mafirimu ekugadzira zvinhu: MHEC inogona kuumba firimu rakatetepa, rinoshanduka kana rakaparadzirwa mumvura.Iyo firimu inoshanda sechipingamupinyi, inoderedza kubuda kwemvura uye ichipa chidziviriro chekudzivirira kuchengetedza unyoro mukati mezvinhu.
Kukora mhedzisiro: Sezvo MHEC ichizvimba mumvura, inoratidza kukora mhedzisiro.Izvi zvinowedzera viscosity zvinobatsira pakuchengetedza mvura zviri nani, kudzivirira mvura kubva pakuparadzana kubva kune zvinhu uye kuchengetedza musanganiswa wakafanana.
Zvikumbiro mukugadzira:
Indasitiri yekuvaka inovimba zvakanyanya neMHEC nekuda kwekuchengetedza mvura.MHEC inobatsira dhaka, grout uye zvimwe cementitious zvinhu nekusimudzira kushanda, kuderedza kuputika nekuvandudza kunamatira.Pamusoro pezvo, MHEC inofambisa kupomba uye kupfapfaidza zvinhu zvekuvaka, zvichiita kuti ive yekuwedzera yakakosha mumaitiro emazuva ano ekuvaka.
Adhesive properties:
Mukuwedzera pakuchengetedza mvura, MHEC inobata basa rinokosha pakuvandudza kunamatira mune zvakasiyana-siyana zvekushandisa.Iyo inonamira zvimiro inonyanya kukosha mune anotevera maindasitiri:
Tile Adhesives: MHEC inowanzoshandiswa mumatairi adhesives kuti iwedzere kusimba kwechisungo pakati pe tile uye substrate.Inoumba mafirimu anoshanduka uye inovandudza kushanda, kuve nechokwadi chisungo chakasimba uye chinogara kwenguva refu.
Wallpaper Pasting: Mukugadzira mapepa ekunamatira, MHEC inobatsira kubatanidza iyo Wallpaper kumadziro.Inodzivirira paste kubva pakuoma nguva isati yakwana uye inosimudzira chisungo chakasimba uye chinogara kwenguva refu.
Joint Compounds: MHEC inoshandiswa muzvikamu zvakabatana nekuda kwekusunga kwayo uye kukora zvinhu.Inobatsira kuwana yakatsetseka uye inonamira kupedzisa mune drywall application.
mukupedzisa:
Methylhydroxyethylcellulose (MHEC) ifaceted cellulose ether ine yakanakisa kuchengetedza mvura uye inonamira zvimiro.Yayo yakasarudzika molecular chimiro, hydrophilicity, firimu-kugadzira kugona uye thickening mhedzisiro inoita kuti ishandiswe zvakanyanya mumaindasitiri akasiyana.Kubva pazvinhu zvekuvaka kuenda kumishonga uye zvizorwa, MHEC inoita basa rakakosha mukuvandudza mashandiro echigadzirwa uye kuve nechokwadi chekushanda kwakakwana.Sezvo maindasitiri achiramba achitsvaga zvakatipoteredza uye zvinobudirira mhinduro, MHEC inoramba iri yakakosha uye yakagadzikana sarudzo yeakasiyana maapplication.
