ho qhibiliha ha metsi ka hydroxyethylcellulose

Hydroxyethylcellulose (HEC) ke polima e qhibilihang ka metsing e atisang ho sebelisoa e le sekontiri se teteaneng, emulsifier, le binder lits'ebetsong tse fapaneng, ho kenyeletsoa lihlahisoa tsa tlhokomelo ea motho, meriana le mekhoa ea indasteri. Sengoliloeng sena se tla hlahloba ho qhibiliha ha metsi ha HEC, ho kenyelletsa le thepa ea eona, melemo le lits'ebetso.

Thepa ea HEC

HEC ke mofuta o fetotsoeng oa selulose o hlahisoang ka ho phekola cellulose ka ethylene oxide. Ts'ebetso ena e fella ka polymer e nang le tekanyo e phahameng ea ho qhibiliha ha metsi, hammoho le lisebelisoa tse ling tse etsang hore e be molemo mefuteng e fapaneng ea likopo. Tse ling tsa thepa ea HEC li kenyelletsa:

  1. Ho qhibiliha ha metsi: HEC e qhibiliha haholo ka metsing, e leng ho etsang hore ho be bonolo ho e kenya ka har'a metsoako le ho fana ka tumellano e babatsehang le lisebelisoa tse ling tse qhibilihang ka metsing.
  2. Bokhoni ba ho nona: HEC e na le bokhoni ba ho tenya litharollo tse nang le metsi, e etsa hore e be molemo lits'ebetsong moo ho batloang ho ts'oana kapa ho ts'oana ha viscous.
  3. Lintho tsa ho etsa lifilimi: HEC e na le thepa ea ho etsa filimi e etsang hore e be molemo lits'ebetsong moo ho batloang tšireletso kapa ho roala.
  4. Botsitso: HEC e tsitsitse ho feta mefuta e mengata ea pH le maemo a mocheso, e leng se etsang hore e be molemo ka mefuta e sa tšoaneng ea lihlahisoa.

Melemo ea HEC Metsi a Sollubility

Ho qhibiliha ha metsi a HEC ho fana ka melemo e mengata e etsang hore e be molemo lits'ebetsong tse fapaneng, ho kenyelletsa:

  1. Kenyelletso e bonolo: Ho qhibiliha ha metsi a phahameng a HEC ho etsa hore ho be bonolo ho kenyelletsa metsoako, kaha e qhibiliha kapele le ha bonolo.
  2. Ho lumellana le lisebelisoa tse ling: HEC e lumellana haholo le lisebelisoa tse ling tse qhibilihang ka metsing, e leng se etsang hore ho be bonolo ho e etsa le lisebelisoa tse ling.
  3. Ts'ebetso e ntlafetseng ea sehlahisoa: Ho qhibiliha ha metsi a HEC ho ka ntlafatsa ts'ebetso ea lihlahisoa ka ho fana ka thepa e teteaneng, emulsifying le ea ho etsa lifilimi.
  4. Nako e fokotsehileng ea ho sebetsa: Ho qhibiliha ha metsi ha HEC ho ka fokotsa nako ea ho sebetsa, kaha ho felisa tlhokahalo ea mehato e eketsehileng ea ho qhaqha polymer.

Lisebelisoa tsa HEC Metsi a Solubility

Ho qhibiliha ha metsi a HEC ho sebelisoa lits'ebetsong tse ngata, ho kenyelletsa:

  1. Lihlahisoa tsa tlhokomelo ea motho ka mong: HEC e atisa ho sebelisoa lihlahisoa tsa tlhokomelo ea botho tse kang li-shampoo, li-conditioner, le lihlapa tsa 'mele e le ntho e matlafatsang le emulsifier.
  2. Meriana ea Meriana: HEC e sebelisoa tlhahisong ea meriana e le setsi se kopanyang, se senyang, le se laoloang-ho lokolloa.
  3. Lijo le lino tse tahang: HEC e sebelisoa indastering ea lijo le lino e le motenya, emulsifier le stabilizer.
  4. Mekhoa ea indasteri: HEC e sebelisoa lits'ebetsong tsa indasteri tse kang ho etsa pampiri, ho etsa pente, le ho cheka oli e le ntho e matlafatsang le ho fetola rheology.

Ho qhibiliha ha metsi a HEC ho bohlokoa ka ho khetheha lits'ebetsong moo ho hlokahalang tekanyo e phahameng ea ho qhibiliha ha metsi, kaha e fana ka tumellano e babatsehang le lisebelisoa tse ling tse qhibilihisang metsi 'me e ka ntlafatsa ts'ebetso ea sehlahisoa.
