Nā ʻokoʻa ma waena o Hydroxypropyl Starch ether a me Hydroxypropyl Methylcellulose i ke kūkulu ʻana.

Hydroxypropyl Starch Etera (HPSE) a meHydroxypropyl Methylcellulose (HPMC)ʻelua mau ʻano polymers hiki ke hoʻoheheʻe ʻia i ka wai i hoʻohana mau ʻia i ka ʻoihana kūkulu. ʻOiai kaʻana like lākou i kekahi mau mea like, aia nā ʻokoʻa koʻikoʻi i kā lākou hana kemika a me nā ʻano hana. Aia ma lalo iho nā ʻokoʻa nui ma waena o Hydroxypropyl Starch Ether a me Hydroxypropyl Methylcellulose i nā noi kūkulu.

1. Hana Kemika:

• HPSE (Hydroxypropyl Starch Ether):
  • Loaʻa ʻia mai ka starch, ʻo ia ka carbohydrate i loaʻa mai nā kumu mea kanu like ʻole.
  • Hoʻololi ʻia ma o ka hydroxypropylation e hoʻonui i kāna mau waiwai.
• HPMC (Hydroxypropyl Methylcellulose):
  • Loaʻa mai ka cellulose, he polymer maoli i loaʻa i loko o nā paia o nā mea kanu.
  • Hoʻololi ʻia ma o ka hydroxypropylation a me ka methylation e hoʻokō i nā waiwai i makemake ʻia.

2. Mea Kumu:

• HPSE:
  • Loaʻa ʻia mai nā kumu lāʻau maloʻo, e like me ke kulina, ka ʻuala, a me ka tapioka.
• HPMC:
  • Loaʻa mai nā kumu cellulose ma muli o nā mea kanu, pinepine i ka pulp lāʻau a i ʻole ka pulupulu.

3. Solubility:

• HPSE:
  • Hōʻike maʻamau i ka hoʻoheheʻe wai maikaʻi, e ʻae i ka hoʻopuehu maʻalahi i nā ʻano wai.
• HPMC:
  • Hiki ke hoʻoheheʻe ʻia i ka wai, e hoʻoheheʻe ʻia i loko o ka wai.

4. Thermal Gelation:

• HPSE:
  • Hiki i kekahi hydroxypropyl starch ethers ke hōʻike i nā waiwai gelation thermal, kahi e piʻi ai ka viscosity o ka hopena me ka mahana.
• HPMC:
  • ʻAʻole hōʻike maʻamau i ka gelation wela, a paʻa mau kona viscosity ma waena o nā ʻano wela.

5. Nā waiwai hana kiʻiʻoniʻoni:

• HPSE:
  • Hiki ke hana i nā kiʻiʻoniʻoni me ka loli maikaʻi a me nā waiwai adhesion.
• HPMC:
  • Hōʻike i nā waiwai hana kiʻiʻoniʻoni, hāʻawi i ka hoʻomaikaʻi ʻana i ka hoʻopili ʻana a me ka hoʻohui ʻana i nā hana kūkulu.

6. Ke kuleana ma ke kūkulu ʻana:

• HPSE:
  • Hoʻohana ʻia i nā noi kūkulu hale no kona mānoanoa, paʻa wai, a me nā waiwai adhesive. Hiki ke hoʻohana ʻia i nā huahana gypsum-based, morta, a me nā mea hoʻopili.
• HPMC:
  • Hoʻohana nui ʻia i ke kūkulu ʻana no kāna hana ma ke ʻano he mānoanoa, ka mea mālama wai, a me ka hoʻonui ʻana i ka hana. Loaʻa maʻamau ia i loko o nā mortar ciment-based, tile adhesives, grouts, a me nā mea hana ʻē aʻe.

7. Kaulike:

• HPSE:
  • Hoʻohālikelike me ka laulā o nā mea hoʻohui a me nā mea hana ʻē aʻe.
• HPMC:
  • Hōʻike i ka hoʻohālikelike maikaʻi me nā mea hana like ʻole a me nā mea hoʻohui.

8. Hoʻonohonoho manawa:

• HPSE:
  • Hiki ke hoʻopili i ka manawa hoʻonohonoho o kekahi mau mea hana kūkulu.
• HPMC:
  • Hiki ke hoʻololi i ka manawa hoʻonohonoho o ka mortar a me nā huahana cementitious ʻē aʻe.

9. Hiki ke hiki:

• HPSE:
  • ʻO nā kiʻiʻoniʻoni i hana ʻia e hydroxypropyl starch ethers e maʻalahi.
• HPMC:
  • Hāʻawi i ka maʻalahi a me ke kūʻē ʻana i nā ʻano hana kūkulu.

10. Nā ʻāpana noi:

• HPSE:
  • Loaʻa i loko o nā ʻano mea hana kūkulu, me ka plaster, putty, a me nā mea hoʻopili.
• HPMC:
  • Hoʻohana maʻamau ʻia i loko o nā mortar ciment-based, tile adhesives, grouts, a me nā mea hana ʻē aʻe.

I ka hōʻuluʻulu ʻana, ʻoiai ʻo Hydroxypropyl Starch Ether (HPSE) a me Hydroxypropyl Methylcellulose (HPMC) e lawelawe i nā kumu like i ke kūkulu ʻana, ʻo ko lākou kumu kemika kūʻokoʻa, nā hiʻohiʻona solubility, a me nā waiwai ʻē aʻe e kūpono iā lākou no nā ʻano hana like ʻole a me nā noi i loko o ka ʻoihana hale. ʻO ka koho ma waena o lākou e pili ana i nā koi kiko'ī o ka mea kūkulu hale a me nāʻano hana i makemakeʻia.
