3. Mmiri na-agbaze:

• Ọrụ Nlekọta Ahụ Ike:
  • Na-egosipụtakarị mmiri dị mma ịgbaze, na-enye ohere maka mgbasa dị mfe na usoro ndị dabere na mmiri.
• HPMC:
  • Mmiri na-agbaze nke ọma, na-emepụta ihe ngwọta doro anya n'ime mmiri.

4. Mmepụta okpomọkụ:

• Ọrụ Nlekọta Ahụ Ike:
  • Ụfọdụ hydroxypropyl starch ethers nwere ike igosipụta njirimara jelation okpomọkụ, ebe viscosity nke ngwọta ahụ na-abawanye ka okpomọkụ na-arị elu.
• HPMC:
  • N'ozuzu, ọ naghị egosipụta okpomọkụ, ọ naghịkwa adịkarị mfe ịhụ ihe dị iche iche.

5. Njirimara Ịmepụta Ihe Nkiri:

• Ọrụ Nlekọta Ahụ Ike:
  • Nwere ike ịmepụta ihe nkiri nwere ezigbo mgbanwe na njirimara njikọta.
• HPMC:
  • Na-egosipụta àgwà ndị na-emepụta ihe nkiri, na-enye aka na mma njikọta na njikọta n'ime usoro ihe owuwu.

6. Ọrụ na Iwu Ụlọ:

• Ọrụ Nlekọta Ahụ Ike:
  • A na-eji ya arụ ọrụ owuwu maka ime ka ọ sie ike, idobe mmiri, na ihe ndị na-eme ka ọ dị nro. A pụrụ iji ya mee ihe na ngwaahịa gypsum, mortars, na gluu.
• HPMC:
  • A na-ejikarị ya arụ ọrụ dịka ihe na-eme ka mmiri sie ike, ihe na-ejide mmiri, na ihe na-eme ka ọrụ dịkwuo mma. A na-ahụkarị ya na ngwa agha e ji simenti mee, ihe na-arapara taịlị, ihe e ji agwakọta ihe, na ihe ndị ọzọ e ji mee ya.

7. Ndakọrịta:

• Ọrụ Nlekọta Ahụ Ike:
  • Dakọtara na ọtụtụ ihe mgbakwunye na ihe owuwu ndị ọzọ.
• HPMC:
  • Na-egosi ezigbo ndakọrịta na ihe owuwu dị iche iche na ihe mgbakwunye.

8. Oge Ịtọ Oge:

• Ọrụ Nlekọta Ahụ Ike:
  • Nwere ike imetụta oge ntọala nke ụfọdụ usoro owuwu.
• HPMC:
  • Nwere ike imetụta oge ntọala nke ngwa agha na ngwaahịa simenti ndị ọzọ.

9. Mgbanwe:

• Ọrụ Nlekọta Ahụ Ike:
  • Ihe nkiri ndị e ji hydroxypropyl starch ethers mepụta na-adịkarị mfe ịgbanwe.
• HPMC:
  • Na-enye aka na mgbanwe na iguzogide mgbawa n'usoro ihe owuwu.

10. Ebe Ngwa:

• Ọrụ Nlekọta Ahụ Ike:
  • A na-ahụ ya n'ọtụtụ ngwaahịa owuwu dị iche iche, gụnyere plasta, putty, na ihe ndị e ji agwakọta ihe.
• HPMC:
  • A na-ejikarị ya eme ihe n'ime ihe e ji simenti rụọ, ihe e ji ejikọta taịlị, ihe e ji kpụọ ihe, na ihe ndị ọzọ e ji arụ ụlọ.

Na nchịkọta, ọ bụ ezie na Hydroxypropyl Starch Ether (HPSE) na Hydroxypropyl Methylcellulose (HPMC) na-arụ ọrụ yiri nke ahụ n'iwu ụlọ, ebe kemịkalụ dị iche iche ha si malite, njirimara ịgbaze agbaze, na ihe ndị ọzọ na-eme ka ha dabara adaba maka nhazi na ojiji dị iche iche n'ime ụlọ ọrụ ụlọ. Nhọrọ dị n'etiti ha dabere na ihe achọrọ kpọmkwem nke ihe owuwu na njirimara arụmọrụ achọrọ.
