Phapang lipakeng tsa Hydroxypropyl Starch ether le Hydroxypropyl Methylcellulose ka Kaho

Hydroxypropyl Starch Ether (HPSE) leHydroxypropyl Methylcellulose (HPMC)ke mefuta e 'meli ea li-polymer tse qhibilihang ka metsi tse sebelisoang haholo indastering ea kaho. Ha ba ntse ba arolelana lintho tse ling tse tšoanang, ho na le liphapang tse ka sehloohong mefuteng ea bona ea lik'hemik'hale le litšobotsi tsa ts'ebetso. Ka tlase ke phapang e kholo lipakeng tsa Hydroxypropyl Starch Ether le Hydroxypropyl Methylcellulose lits'ebetsong tsa kaho:

1. Sebopeho sa Lik'hemik'hale:

• HPSE (Hydroxypropyl Starch Ether):
  • E tsoa ho starch, e leng carbohydrate e fumanoang mehloling e fapaneng ea limela.
  • E fetotsoe ka hydroxypropylation ho ntlafatsa thepa ea eona.
• HPMC (Hydroxypropyl Methylcellulose):
  • E tsoa ho cellulose, polymer ea tlhaho e fumanehang maboteng a lisele tsa limela.
  • E fetotsoe ka hydroxypropylation le methylation ho fihlela thepa e lakatsehang.

2. Litaba tsa Mohloli:

• HPSE:
  • E fumanoa mehloling ea setache e thehiloeng limela, joalo ka poone, litapole, kapa tapioca.
• HPMC:
  • E tsoa mehloling ea selulose e thehiloeng limela, hangata makhasi a lehong kapa k'hothone.

3. Sollubility:

• HPSE:
  • Ka tloaelo e bonts'a ho qhibiliha ha metsi hantle, ho lumella ho hasana habonolo mefuteng e thehiloeng metsing.
• HPMC:
  • Ho qhibiliha ha metsi haholo, ho etsa litharollo tse hlakileng ka metsing.

4. Thermal Gelation:

• HPSE:
  • Li-ether tse ling tsa hydroxypropyl starch li ka bonts'a thepa ea gelation ea mocheso, moo viscosity ea tharollo e eketsehang ka mocheso.
• HPMC:
  • Ka kakaretso ha e bontše gelation ea mocheso, 'me viscosity ea eona e lula e tsitsitse ho pholletsa le mefuta e mengata ea mocheso.

5. Lintho tsa ho Etsa Lifilimi:

• HPSE:
  • E ka theha lifilimi tse nang le thepa e ntle ea ho fetoha le maemo.
• HPMC:
  • E bonts'a thepa ea ho etsa lifilimi, e kenyang letsoho ho ntlafatseng ho khomarela le ho kopanya ha ho etsoa kaho.

6. Seabo Kahong:

• HPSE:
  • E sebelisoa lits'ebetsong tsa kaho bakeng sa ho teteana ha eona, ho boloka metsi, le thepa ea sekhomaretsi. E ka sebelisoa lihlahisoa tse thehiloeng ho gypsum, seretse le sekhomaretsi.
• HPMC:
  • E sebelisoa haholo moahong bakeng sa karolo ea eona e le setenya, sesebelisoa sa ho boloka metsi, le se matlafatsang ts'ebetso. Hangata e fumanoa liretseng tse entsoeng ka samente, li-adhesives tsa lithaele, li-grouts, le mekhoa e meng.

7. Ho lumellana:

• HPSE:
  • E lumellana le mefuta e mengata ea li-additives le lisebelisoa tse ling.
• HPMC:
  • E bonts'a tumellano e ntle le lisebelisoa tse fapaneng tsa kaho le li-additives.

8. Ho beha Nako:

• HPSE:
  • E ka ama nako ea tlhophiso ea litlhophiso tse itseng tsa kaho.
• HPMC:
  • E ka susumetsa nako ea ho beha seretse le lihlahisoa tse ling tsa cementitious.

9. Ho feto-fetoha ha maemo:

• HPSE:
  • Lifilimi tse entsoeng ka hydroxypropyl starch ethers li atisa ho fetoha habonolo.
• HPMC:
  • E kenya letsoho ho feto-fetoha ha maemo le ho hanyetsa ha crack ha ho etsoa kaho.

10. Libaka tsa Kopo:

• HPSE:
  • E fumaneha lihlahisoa tse fapaneng tsa kaho, ho kenyeletsoa samente, putty, le li-adhesive formulations.
• HPMC:
  • Hangata e sebelisoa liretseng tse entsoeng ka samente, likhomaretsi tsa lithaele, li-grouts le lisebelisoa tse ling tsa kaho.

Ka kakaretso, ha bobeli ba Hydroxypropyl Starch Ether (HPSE) le Hydroxypropyl Methylcellulose (HPMC) ba sebeletsa merero e ts'oanang ea kaho, tšimoloho ea bona ea lik'hemik'hale tse fapaneng, litšobotsi tsa ho qhibiliha, le lisebelisoa tse ling li etsa hore li tšoanelehe bakeng sa mefuta e sa tšoaneng ea lihlahisoa le lisebelisoa ka har'a indasteri ea mohaho. Khetho pakeng tsa bona e itšetlehile ka litlhoko tse khethehileng tsa thepa ea kaho le litšobotsi tse lakatsehang tsa ts'ebetso.
