1. Chii chinonzi hydroxyethyl cellulose (HEC)?
Hydroxyethyl cellulose (HEC)chinhu chakasikwa chepolymer compound uye cellulose derivative. Iyo inonyungudika nemvura inonyungudika ether inowanikwa nekuita kwe cellulose ne ethylene oxide. Iyo kemikari chimiro chehydroxyethyl cellulose ine basic skeleton ye cellulose, uye panguva imwe chete inounza hydroxyethyl (-CH2CH2OH) inotsiva mucheni yayo yemamorekuru, iyo inopa kunyungudika kwemvura uye zvimwe zvemuviri nemakemikari zvimiro. Iyo isiri-chepfu, isingatsamwire uye biodegradable kemikari inoshandiswa zvakanyanya mumaindasitiri akasiyana.
2. Kuita kwehydroxyethyl cellulose
Kunyungudika kwemvura: Hydroxyethyl cellulose ine kunyungudika kwakanaka mumvura uye inogona kukurumidza kunyungudutswa mumvura inotonhora kana inopisa kuti iite viscous solution. Iyo solubility inowedzera nekuwedzera kweiyo dhigirii yehydroxyethylation, saka ine yakanaka controllability mumaindasitiri ekushandisa.
Viscosity maitiro: Iyo mhinduro viscosity yehydroxyethyl cellulose yakanyatsoenderana neiyo molecular uremu, dhigirii re hydroxyethylation uye kusangana kwemhinduro. Viscosity yaro inogona kugadziridzwa mumashandisirwo akasiyana kuti asangane neyakasiyana maitiro zvinodiwa. Pakudzika kwakadzika, inozvibata seyakadzika-viscosity mhinduro, nepo pakakwirira, iyo viscosity inowedzera nokukurumidza, ichipa yakasimba rheological properties.
Nonionicity: Hydroxyethyl cellulose is nonionic surfactant iyo isingakanganisike nekuchinja kwepH kukosha kwemhinduro, saka inoratidza kugadzikana kwakanaka pasi pemamiriro akasiyana ezvakatipoteredza. Ichi chivakwa chinoita kuti chishandiswe zvakanyanya mumagadzirirwo mazhinji anoda kugadzikana.
Kukora: Hydroxyethyl cellulose ine yakanaka yekukora zvivakwa uye inoshandiswa seyakakora mune akawanda-based formulations. Inogona kunyatso kuwedzera viscosity yemvura uye kugadzirisa fluidity uye kushanda kwechigadzirwa.
Kugadzira firimu uye emulsifying zvivakwa: Hydroxyethyl cellulose ine mamwe mabhaisikopo-ekugadzira uye emulsifying zvimiro, uye inogona kuparadzira zvakadzika zvimisikidzo zvakasiyana mumultiphase system. Iyi pfuma inonyanya kukosha mumaindasitiri ezvekuzora uye machira.
Thermal kugadzikana uye solubility:Hydroxyethyl celluloseyakanyatsogadzikana pakupisa, inogona kuchengetedza kunyungudika kwayo uye kushanda mukati meimwe tembiricha yemhando, uye kuenderana nezvinodiwa zvenzvimbo dzekushisa kwepamusoro. Ichi chivakwa chinoita kuti zvive zvakanakira kushandiswa mune dzimwe nzvimbo dzakakosha.
Biodegradability: Nekuda kweiyo yakasikwa cellulose sosi, hydroxyethyl cellulose ine yakanaka biodegradability, saka haina zvainokonzeresa nharaunda uye iine hushamwari zvinhu.
3. Minda yekushandisa yehydroxyethyl cellulose
Indasitiri yekuvaka uye yekuputira: Hydroxyethyl cellulose inowanzoshandiswa seyakakora uye inochengetedza mvura muindasitiri yekuvaka, uye inoshandiswa zvakanyanya mumatope esimende, anonamira, dhaka rakaoma uye zvimwe zvigadzirwa. Inogona kuvandudza kushanda uye fluidity yezvinhu, kuvandudza kunamatira uye kusapinda kwemvura kuita kwejira. Nekuda kwekuchengetedza kwayo kwakanaka kwemvura, inogona kunyatso kuwedzera nguva yakavhurika yezvinhu, kudzivirira kubuda kwemvura nekukurumidza, uye kuve nechokwadi chekuvaka mhando.
Oiri yekuchera uye yekuchera mvura: Mukubvisa oiri, hydroxyethyl cellulose inoshandiswa seyakakora yekuchera mvura yekuchera uye kupera kwemvura, iyo inogona kunyatso gadzirisa rheology yemvura, kudzivirira kuiswa kwedhaka pamadziro etsime uye kudzikamisa tsime remadziro chimiro. Inogonawo kuderedza kupinda kwemvura uye kuvandudza kushanda uye kuchengeteka kwekuchera.
Cosmetics industry:Hydroxyethyl celluloseinoshandiswa zvakanyanya muzvigadzirwa zvekuchengetedza ganda, shampoo, gel yekugeza, cream cream uye zvimwe zvigadzirwa seyakakora, emulsifier uye stabilizer muzvizoro. Inogona kuwedzera viscosity yechigadzirwa, kuvandudza kuyerera kwechigadzirwa, kuwedzera kunzwa kwechigadzirwa, uye zvakare kugadzira firimu rinodzivirira paganda kuti ribatsire kunyorova uye kudzivirira.
Indasitiri Yemishonga: Hydroxyethyl cellulose inoshandiswa semushonga binder, inosimudzira-kuburitsa mumiririri, uye yekuzadza mahwendefa nemakapisi muindasitiri yemishonga. Inogona kuvandudza zvinhu zvemuviri zvekugadzirira zvinodhaka uye kuwedzera kugadzikana uye bioavailability yemishonga.
Indasitiri yeMachira neMapepa: Muindasitiri yemachira, hydroxyethyl cellulose inogona kushandiswa seyekubatsira dhayi uye kudhinda kunobatsira kuvandudza kudhaya kufanana uye kupfava kwemachira. Muindasitiri yekugadzira mapepa, inoshandiswa seyakakora mumapepa ekuputira kuvandudza kunaka kwekudhinda uye kupenya kwepamusoro kwepepa.
Indasitiri Yezvekudya: Hydroxyethyl cellulose inoshandiswawo mukugadzira chikafu, kunyanya seyakakora, emulsifier uye stabilizer. Inogona kugadzirisa kuravira uye kugadzirwa kwechikafu, semuenzaniso, mu ice cream, jelly uye zvinwiwa, inogona kuvandudza kugadzikana uye kunaka kwechigadzirwa.
Zvekurima: Mumunda wekurima, hydroxyethyl cellulose inowanzoshandiswa mukugadzirira mishonga yezvipembenene, machira efetereza uye zvigadzirwa zvekudzivirira chirimwa. Kukora uye kunyorovesa zvinhu zvinobatsira kuvandudza kufanana uye kunamatira kwevamiririri vekupfapfaidza, nokudaro vachivandudza kushanda kwemishonga yezvipembenene uye kuderedza kusvibiswa kune zvakatipoteredza.
Makemikari ezuva nezuva: Mukuchenesa imba uye zvigadzirwa zvekuchengeta munhu, hydroxyethyl cellulose inoshandiswa seyakakora uye inosimbisa kuwedzera mashandisiro ekushandisa uye kunzwa kwechigadzirwa. Semuyenzaniso, inowanzoshandiswa mumakemikari emazuva ese akadai sezvinwiwa zvekusuka ndiro, zvekugezesa mbatya, uye kuchenesa kumeso.
Hydroxyethyl celluloseimhando yepamusoro yemamolecular ine hunyanzvi hwekuita uye huwandu hwakawanda hwekushandisa. Kunyungudika kwayo kwemvura kwakanaka, kukora, kugadzikana kwemafuta uye biodegradability inoita kuti ishandiswe zvakanyanya muminda yakawanda senge kuvaka, peturu, zvizorwa, mishonga, uye machira. Nekuvandudzwa kwezvinodiwa zvekuchengetedza kwezvakatipoteredza uye kufambira mberi kwetekinoroji, tarisiro yekushandiswa kweHEC ichave yakakura uye ichave sarudzo yakakosha yezvinhu zvakasvibirira zvekuchengetedza kwezvakatipoteredza uye zvinoshanda zvekuwedzera.
