Thepa ea 'Mele ea Hydroxyethyl cellulose

Hydroxyethyl cellulose (HEC) ke polymer e qhibilihang ka metsing e nkiloeng ho cellulose. E sebelisoa haholo liindastering tse fapaneng ka lebaka la thepa ea eona e ikhethang ea 'mele. Tse ling tsa litšobotsi tsa bohlokoa tsa 'mele tsa hydroxyethyl cellulose li kenyelletsa:

1. Ho qhibiliha: HEC e qhibiliha ka metsing 'me e etsa litharollo tse hlakileng, tse tiileng. Ho qhibiliha ha HEC ho ka fapana ho latela lintlha tse kang tekanyo ea ho nkeloa sebaka (DS) ea lihlopha tsa hydroxyethyl le boima ba limolek'hule ba polymer.
2. Ho thibana ha metsi: HEC e na le ho thibana ho hoholo ka hara tharollo, e ka fetoloang ke mabaka a fapaneng a kang mahloriso a polymer, mocheso le sekhahla sa ho beola. Litharollo tsa HEC hangata li sebelisoa e le metsoako e teteanang lits'ebetsong tse fapaneng, ho kenyeletsoa le pente, likhomaretsi le lihlahisoa tsa tlhokomelo ea motho ka mong.
3. Bokhoni ba ho Etsa Filimi: HEC e na le bokhoni ba ho etsa lifilimi tse tenyetsehang le tse kopaneng ha li omisoa. Thepa ena e sebelisoa lits'ebetsong tse kang ho koahela matlapa le likhasepheng meriana, hammoho le litlolong le lihlahisoa tsa tlhokomelo ea botho.
4. Ho Boloka Metsi: HEC e na le thepa e ntle ea ho boloka metsi, e leng se etsang hore e be polymer e atlehang e qhibilihang metsing bakeng sa ho sebelisoa thepa ea kaho e kang li-mortar, grouts le render. E thusa ho thibela tahlehelo ea metsi ka potlako nakong ea ho kopanya le ho sebelisa, ho ntlafatsa ho sebetsa le ho khomarela.
5. Ho Tsitsisa Thempereichara: HEC e na le botsitso bo botle ba thempereichara, e boloka thepa ea eona holim'a mefuta e fapaneng ea thempereichara. E ka mamella mocheso oa ts'ebetso o kopanang le liindasteri tse fapaneng ntle le ho senyeha ho hoholo.
6. Botsitso ba pH: HEC e tsitsitse holim'a mefuta e mengata ea pH, e leng se etsang hore e lokele ho sebelisoa mefuteng e nang le maemo a asiti, a sa nke lehlakore, kapa a alkaline. Thepa ena e lumella tšebeliso ea eona lits'ebetsong tse fapaneng ntle le matšoenyeho mabapi le ho senyeha ho amanang le pH.
7. Ho tsamaellana: HEC e tsamaellana le mefuta e meng e mengata, ho kenyeletsoa le letsoai, li-acid le li-solvent tsa tlhaho. Ho tsamaellana hona ho lumella ho etsoa ha litsamaiso tse rarahaneng tse nang le thepa e etselitsoeng liindasteri tse kang meriana, tlhokomelo ea botho le kaho.
8. Ho bola ha lintho tse phelang: HEC e nkiloe mehloling e nchafatsoang joalo ka lepolanka la patsi le k'hothone, e leng se etsang hore e bola ha lintho tse phelang le ho ba mosa tikolohong. Hangata e ratoa ho feta li-polymer tsa maiketsetso lits'ebetsong moo ho amehang botsitso.

Thepa ea 'mele ea hydroxyethyl cellulose (HEC) e etsa hore e be tlatsetso ea bohlokoa liindastering tse fapaneng, moo e tlatsetsang ts'ebetsong, botsitso le ts'ebetsong ea mefuta e mengata ea lihlahisoa le liforomo.
