Chemistry ea Methocele ™

Methocel™ ke mofuta oa ethe ea celluulothe e hlahisoang ke DoW. Ethe e se-ena e bo-'mè ea selefouno e tsoa ho selefoui, polymer ea tlhaho e fumanehang maboteng a limela. Khemistrical ea Methocele ™ e kenyelletsa pherekano ea cellulose ka karabelo ea chelete. Mefuta ea mantlha ea Metholl ™ e kenyelletsa hydroxypropyproppyl methylcelllllll (HPMC) le methylcelllulose (MC), e 'ngoe le e' ngoe e nang le litšobotsi tse ikhethang tsa lik'hemik'hale. Mona ke kakaretso e akaretsang ea k'hemistry ea Methocele ™:

1. HydroxypropyL methylcelllulose (HPMC):

• Sebopeho:
  • HPMC ke cellulose e nang le metsi a qhibilihileng ea metsi e nang le likeleli tse peli tsa 'mele: HydroxypropypropyL (HP) le methyl (m) lihlopha.
  • Lihlopha tsa hydroxypropyl li hlahisa ts'ebetso ea hydrophilic, ntlafatsallo ea metsi.
  • Lihlopha tsa methyl li kenya letsoho bakeng sa solubity le tšusumetso ea thepa ea polymer.
• Karabelo ea Etheright:
  • HPMC e hlahisoa ka bongata ba cellulose ea celloulose e nang le litlatsetso tsa pokello ea khomo
  • Maemo a sebelisitsoe ka hloko ho fihlela tekanyo e lakatsehang ea sebaka (DS) bakeng sa sebaka sa hydroxypropyl le lihlopha tsa methyl.
• LITLHAKISO:
  • HPMC e bonts'a lillo tse ntle tsa metsi, thepa e etsang lifilimi, 'me e ka thusa ho lokolloa ha meriana likopo tsa meriana.
  • Boemo ba ho nka karolo ho susumetsa pono ea polytrice, ho boloka metsing le thepa e 'ngoe.

2. MethylcelLulose (MC):

• Sebopeho:
  • MC ke selefounu ether le lithyl tse ntle.
  • Hoa tšoana le HPMC empa e haelloa ke lihlopha tsa hydroxyproPyl.
• Karabelo ea Etheright:
  • MC e hlahisoa ke celpelose e nang le tšepe e nang le methyl chloride.
  • Maemo a karabelo a laoloa ho fihlela sebaka se lakatsehang.
• LITLHAKISO:
  • MC e qhibiliha metsi ka metsi mme e na le lits'ebetso tsa meriana, kaho le indastering ea lijo.
  • E sebelisoa e le mophaphathehi, thickener le tsietsing.

3. Thepa e tloaelehileng:

• Sello sa metsi: Ka bobeli HPMC le MC li qhibiliha ka metsing a batang, a theha tharollo e hlakileng.
• Phetoho ea lifilimi: Li ka theha lifilimi tse tenang le tse kopaneng, li li etsa tse sebetsang lits'ebetsong tse fapaneng.
• Thickening: Li-Ether tsa selefounul ™ e hlahisa liketsahalo tse matla, tse amang maikutlo a tharollo.

4. Likopo:

• Meriana: E sebelisoa ka har'a maqhubu a matlapeng, lithunya le linonyana tse laoloang ke tsona.
• Kaho: O sebetsa ka liluma, likhoebo tsa taile le thepa e 'ngoe ea moaho.
• Lijo: E sebelisoa e le li-thickeners lihlahisoa tsa lihlahisoa tsa lijo.
• Tlhokomelo ea Botho: E fumaneha ka litlolo, Shampoos le lintho tse ling tsa tlhokomelo ea motho.

Khemistrical ea Ethe ea Methocele ™ e etsa hore thepa e feto-fetohang ka lits'ebeletso tse fapaneng, e fana ka taolo ho thepa ea liphiri tsa li-ruoloji ea phetisetsong. Meru e ikhethang e ka tsamaisana ka ho fetola boemo ba sebaka le liparame tse ling tsa ho etsa.
