Zvivakwa uye zvinoshandiswa zveHydroxyTHYL Cellulose (Hec)

1. Zvivakwa zveHydroxyTHYL Cellulose
HydroxytHyl Cellulose (HEC, HydroxyTH Cellerose) inhengo yemvura ine mvura yakawanikwa nemakemikari yekugadziridzwa kwemasikirwo emusango cellulose. Chimiro chayo chinoumbwa neye glucose zvikamu zvakabatana ne β-1,4-glycosic zvisungo. HydroxytHyl mapoka (-Ch2ch2oh) anounzwa muHydroxyTH Cellulose Moleulose Molelloles, ayo anobatanidza neHydroxyl mapoka emheremalose kuburikidza nemakemikari maitiro. Nekuda kwekugadziridzwa uku, hec ine zvakawanda zvivakwa zvakasiyana kubva kune yekutanga cellulose.

Zvivakwa zvemuviri
Chitarisiko: Hec inowanzove chena kana kubva kune chena-chena amorphous poda neine fluidity.
Solubility: Hec inochema mumvura, kunyanya mumvura inotonhora, ichigadzira mhinduro viscous. Izvi zvinokonzerwa neHydrogen kusungwa pakati peiyo hydroxyt broub uye mamorekuru emvura, ayo anogonesa helc aburudzwe mumvura.
Viscosity: Mhinduro yeHec mumvura inoratidza viscossity yakakwira, uye viscosity yakanyatsoenderana neyekunyorwa nehuremu hwemanyorerwe uye kusunganidzwa kwemhinduro. Kazhinji, vhiza yehec inowedzera nekuwedzera kwehuremu hwemanyorerwe.
Kugadziriswa kweTermal: Hec ine yakanaka yekudzikama yekugadzikana uye inogona kuchengetedza yakagadzikana kuita mukati meimwe tembiricha yekupisa. Kazhinji, hec inogona kutsungirira kupisa kwakanyanya, asi kuita kwayo kuchadzikira mushure mekuwedzera tembiricha.

Zvemakemikari zvivakwa
Nzvimbo yepamusoro: Iyo hydroxyteth yeboka muHec Molecule ndeye hydrophilic, iyo inobvumira hyc yekuumba mhinduro yakagadzikana mumvura uye kugadzirisa nzvimbo yekuvandudza.
Kuwedzeredza: Nekuchinja mamiriro ekuita mumakemikari, iyo molecular uremu, solubility, visucosity uye zvimwe zvivakwa zvehec zvinogona kugadziriswa kuti usashandise zvakasiyana zvinoshandiswa zvinoshandiswa.
PH Sungika: Hec yakagadzikana mune isina kwayakarerekera kana isina kusimba alkaline nharaunda, asi iyo solubility inogona kukanganisika kune imwe nhanho iri pasi pemamiriro ezvinhu akasimba kana alkaline mamiriro.

2. Kushandisa kwehydroxyethyl cellulose
Nekuda kwezvakawanda zvakanakisa zvivakwa, hec yakave ichishandiswa zvakanyanya muminda dzakasiyana siyana. Izvo zvinoshandiswa zvinosanganisira zvinosanganisira zvinotevera zvikamu:

Indasitiri yekuvaka muindasitiri yekuvaka, hec inowanzo shandiswa seyakawedzera kuti zvinhu zvekuvakisa, kunyanya kuSimende, Gypsum, majasi, zvinonamatira uye zvimwe zvigadzirwa. Hec inogona kuvandudza kusarudzika, fluidity uye kuiswa kwezvinhu izvi. Mukuwedzera, hec inogona zvakare kuvandudza kuchengetwa kwemvura yemutya, kwatambanudza nguva yekuvakwa, uye kudzivirira simende kubva pakuisa nekukurumidza. Nekuda kwezvinhu zvaro zvakakora, hec zvinogona kuvandudza kufukidzwa uye kuderedza kwekuzvidzora kwemakosi.

Dailymical emakemikari indasitiri yemitambo yezuva nezuva Basa guru reHec mune izvi zvigadzirwa rakaita sediki, kumhanyisa mumiririri, emulsifier uye stabilizer. HEC inogona kubatsira zvigadzirwa kuchengetedza viscossity yakakodzera, ipa kunzwa kwakanaka kwekushandiswa, uye kugadzirisa kusimba kwechigadzirwa. Uye zvakare, hec inogona zvakare kugadzirisa zvivakwa zvetsiva zvekudzivirira kuti uve nechokwadi chekufanana kwavo uye kushanda panguva yekushandisa.

Chikafu Chekudya Hec chinoshandiswa sedhizaini, stabilizer uye emulsifier muindasitiri yechikafu, kunyanya mune zvekudya senge ice cream, muto, comics uye salad zvipfeko. Nekuti hec ine yakanaka mvura solubility, inogona kuvandudza kuravira uye kuwanda kwechikafu, kuwedzera hukama hwezvigadzirwa, kuvandudza hunhu hwekudya, uye kuwedzera hupenyu hwesherufu.

Indasitiri yechechi muindasitiri yemishonga, hec inonyanya kushandiswa semutakuri, emulsififier, inonamatira uye yakasimba yezvinodhaka. Izvo zvinoshandiswa kugadzirira mishonga yemuromo, mafuta ezimusi, maGels, ziso rekugadzirira zvinodhaka, hec anogona kudzora huwandu hwezvinodhaka, chengetedza kugadzikana kwezvinodhaka, uye kuvandudza bioavilalility yemishonga.

Sangano remunda hec rinowanikwa zvakanyanya mukurima seyekudzivirira chirimwa mumiriri, pesticaride emulsifier uye fetiraizer thickener. Zvinogona kuvandudza kuparadzirwa kwemishonga yekuuraya zvipembenene, batsira zvipuka zvechipfuva kuti vasiye zvakanyanyisa uye kuvandudza kuderedza mishonga yekuuraya zvipuka. Panguva imwecheteyo, hec inogona zvakare kuvandudza kugadzikana kwefetiraiza, kuderedza kurasikirwa kwefetiraiza muvhu, uye kuwedzera kugona kwekushandiswa kwefetiraiza.

Sindasitiri yechipfuva hec inoita basa rakakosha muindasitiri yePetroleum, kunyanya mukurovedza mvura uye nemafuta emakemikari. Iyo inoshandiswa seyakakwenenzverwa, kumhanyisa mumiririri uye stabilizer. HEC inogona kuwedzera iyo visikopa yekukwevera mvura yemvura uye kusimudzira kutakura kugona kwezvinwiwa, kuitira kuti zvibate zvinobudirira kutakura marara pakukwevera panguva yekudhirowa. Panguva imwecheteyo, hec inogona zvakare kudzivirira kusvetuka kwemvura mumafuta uye gasi matsime panguva yekukwevera kuti ive nechokwadi chekufambira mberi kwekuita.

HydroxytHyl Cellulose (Hec) inguva-yakashata polymer zvinyorwa zvine chekuita nekuita kwakanaka. Yayo yakasarudzika yakakura uye kugadzikana uye yakanaka mvura solubility inoita kuti ishandiswe zvakanyanya mumaindasitiri akawanda sekuvaka, makemikari ezuva nezuva, chikafu, kurima uye petroleum. Nekuvandudzwa kwehunyanzvi, maitiro ekugadzira uye kutonga kwehyoko kweec kuchapfuurira nekuvandudza, uye tarisiro dzayo dzekushandisa dzichava dzakawedzera.
