I-Hydroxy ethyl methyl cellulose

IHydroxy ethyl methyl cellulose (HEMC), eyaziwa nangokuthi i-methyl hydroxy ethyl cellulose (MHEC), iyi-polymer eguquguqukayo etholakala ku-cellulose. Ihlanganiswa ngokuguqulwa kwamakhemikhali e-cellulose, okuholela ekwakhiweni okunezici eziyingqayizivele ezifanele ukusetshenziswa kwezimboni ezihlukahlukene. I-HEMC iyilungu lomndeni we-cellulose ether futhi yabelana ngokufana nokunye okuphuma kokunye okufana ne-methyl cellulose (MC) ne-hydroxypropyl methyl cellulose (HPMC).

Izakhiwo Ezibalulekile ze-Hydroxy ethyl Methyl Cellulose (HEMC):

I-1.I-Solubility Yamanzi: I-HEMC iyancibilika emanzini, yenza izixazululo ezicacile nezibonakalayo. Lesi sakhiwo sivumela ukuphathwa kalula nokufakwa ezinhlelweni ezinamanzi, okuyenza ifaneleke ukusetshenziswa ezinhlobonhlobo zokwakheka.

I-2.I-Thickening Agent: I-HEMC isebenza njenge-ejenti yokuqina ephumelelayo ekwakhiweni okusekelwe emanzini. Lapho ehlakazeka emanzini, amaketanga e-polymer e-HEMC ahlanganisa futhi enze isakhiwo senethiwekhi, okwandisa i-viscosity yesisombululo. Le ndawo ibalulekile ekulawuleni i-rheology nokugeleza kwezakhiwo zamapende, izinto zokunamathisela, neminye imikhiqizo ewuketshezi.

I-3.Ikhono Lokwenza Ifilimu: I-HEMC inamandla okwenza amafilimu lapho isetshenziswa ezindaweni ezingaphezulu futhi ivunyelwe ukuba yome. Lawa mafilimu asobala, aguquguqukayo, futhi abonisa ukunamathela okuhle kuma-substrates ahlukahlukene. Amafilimu e-HEMC asetshenziswa ezinhlelweni ezinjengama-coatings, ama-adhesives, nezinto zokwakha.

4.Ukugcinwa Kwamanzi Okuthuthukisiwe: I-HEMC yaziwa ngezindawo zayo zokugcina amanzi, okusiza ukuvimbela ukulahlekelwa umswakama nokugcina ukuvumelana okufunayo kokubunjwa ngokuhamba kwesikhathi. Lesi sakhiwo siwusizo ikakhulukazi ezintweni zokwakha ezifana nodaka, ama-grouts, nezinamatheliso zamathayili, lapho kudingeka khona ukusebenza isikhathi eside.

I-5.Ukusebenza Okuthuthukisiwe Nokunamathela: Ukwengezwa kwe-HEMC ekubunjweni kungathuthukisa ukusebenza ngokuthuthukisa ukugeleza nokusabalala kwezinto. Iphinde ikhuthaze ukunamathela kuma-substrates, okuholela ekuhlanganisweni okungcono nokusebenza komkhiqizo wokugcina.

I-6.Ukuqiniswa kwe-Emulsions kanye nokumiswa: I-HEMC isebenza njenge-stabilizer kuma-emulsions kanye nokumiswa, ukuvimbela ukuhlukaniswa kwesigaba nokuxazulula izinhlayiya. Lesi sakhiwo sisiza ukugcina i-homogeneity nokuzinza kokubunjwa, ukuqinisekisa ikhwalithi yomkhiqizo engaguquki.

I-7.Ukuhambisana Nezinye Izithasiselo: I-HEMC ihambisana nohlu olubanzi lwamanye amakhemikhali nezithasiselo, okuhlanganisa ama-pigments, ama-filler, nama-rheology modifiers. Ingafakwa kalula ekwakhiweni okuyinkimbinkimbi ukuze kuzuzwe izici zokusebenza ezifiselekayo.

Izicelo ze-Hydroxy ethyl Methyl Cellulose (HEMC):

I-1.Izinto Zokwakha: I-HEMC isetshenziswa kakhulu embonini yezokwakha njenge-thickener, i-ejenti yokugcina amanzi, kanye ne-binder kuma-mortar asekelwe kusimende, ama-plaster, nama-adhesives ama-tile. Ithuthukisa ukusebenza, ukunamathela, nokumelana nokucwila kwalezi zinto, okuholela ekusebenzeni okuthuthukisiwe nokuqina.

I-2.Paints and Coatings: I-HEMC iqashwe njenge-rheology modifier, i-thickener, kanye ne-stabilizer kumapende asekelwe emanzini, ama-coatings, noyinki. Ithuthukisa ukuhlakazeka kwe-pigment, ivimbele ukuwohloka, futhi ithuthukise izakhiwo zokusetshenziswa zalezi zakhiwo.

I-3.Adhesives and Sealants: I-HEMC isetshenziselwa ukunamathela kanye nama-sealants ukuze kuthuthukiswe amandla okubopha, i-tack, kanye nesikhathi esivulekile. Isebenza futhi njenge-ejenti yokuqina kanye ne-rheology modifier, ihlinzeka nge-viscosity oyifunayo kanye nezakhiwo zokugeleza zokusetshenziswa.

4.Imikhiqizo Yokunakekelwa Komuntu Siqu: I-HEMC ithola izinhlelo zokusebenza emikhiqizweni yokunakekela yomuntu siqu efana nokhilimu, izinto zokuthambisa, namashampoos njengokujiya, ukuzinzisa, kanye nefilimu yangaphambili. Inikeza ukuthungwa okufiselekayo, ukungaguquguquki, kanye nezakhiwo ze-rheological kulezi zakhiwo.

5.Ezemithi: Ekwenziweni kwemithi, i-HEMC isebenza njenge-binder, disintegrant, kanye ne-ejenti ekhishwayo elawulwayo kumaphilisi, amaphilisi, namafutha okugcoba. I-biocompatibility yayo kanye nokuncibilika kwamanzi kuyenza ifanele ukusetshenziswa komlomo kanye ne-topical.

6.Imboni Yokudla: Nakuba ingajwayelekile kangako, i-HEMC iphinde isetshenziswe embonini yokudla njengokujiya, ukuqiniswa, kanye ne-emulsifier emikhiqizweni ethile efana namasoso, okokugqoka, nama-dessert.

IHydroxy ethyl Methyl Cellulose (HEMC) iyi-polymer eguquguqukayo enezinhlelo zokusebenza ezihlukahlukene kuzo zonke izimboni eziningi. Ukuncibilika kwayo emanzini, izakhiwo ezijiyayo, ikhono lokwenza ifilimu, nokuhambisana nezinye izithasiselo kuyenza ibe yigugu ekwakhiweni, opende nezingubo zokunamathisela, izinto zokunamathisela, imikhiqizo yokunakekela abantu, imithi, kanye nokwakhiwa kokudla. Njengoba imizamo yocwaningo nentuthuko iqhubeka, i-HEMC kulindeleke ukuthi ibambe iqhaza elikhulayo ezinqubweni zesimanje zezimboni.
