ʻO nā etera cellulose| Ka pauda polimer hiki ke hoopau hou ia

Cellulose ethersa me Redispersible Polymer Powder (RPP) ʻelua mau papa ʻokoʻa o nā mea, kēlā me kēia me kāna mau waiwai ponoʻī a me nā noi. E ʻimi kākou i kēlā me kēia māhele:

Cellulose Ethers:

1. Wehewehe:

• ʻO nā cellulose ethers he ʻohana o nā polymers hiki ke hoʻoheheʻe ʻia i ka wai i loaʻa mai ka cellulose, kahi polymer kūlohelohe i loaʻa i nā paia o nā mea kanu.

2. Nā ʻano:

• ʻO nā ʻano maʻamau o ka cellulose ethers me Methyl Cellulose (MC), Hydroxyethyl Cellulose (HEC), Hydroxypropyl Cellulose (HPC), a me Hydroxypropyl Methylcellulose (HPMC).

3. Waiwai:

• Hiki ke hoʻoheheʻe ʻia i loko o ka wai: ʻO nā cellulose ethers he mea hiki ke hoʻoheheʻe ʻia i ka wai, e hana ana i nā gel alohilohi.
• Viscosity: Hiki iā lākou ke hoʻololi i ka viscosity o nā hoʻonā, e kūpono iā lākou no nā noi like ʻole.
• Kiʻiʻoniʻoni: Nui nā cellulose ethers i loaʻa nā waiwai hana kiʻiʻoniʻoni.

4. Nā noi:

• ʻO nā lāʻau lapaʻau: Hoʻohana ʻia e like me nā mea hoʻopaʻa, nā mea hoʻokaʻawale, a me nā mea hoʻonaninani kiʻiʻoniʻoni i loko o nā ʻano papa.
• Hana ʻia: Hoʻohana ʻia i loko o ka mortar, sima, a me nā mea hoʻopili tile no ka hoʻomaikaʻi ʻana i ka hana a me ka hoʻopili ʻana.
• ʻOihana Meaʻai: Hoʻohana ʻia e like me nā mānoanoa a me nā stabilizer i nā huahana meaʻai like ʻole.
• Nā huahana mālama pilikino: Loaʻa i loko o nā mea hoʻonaninani, nā lotion, a me nā shampoos no ko lākou mānoanoa a hoʻopaʻa i nā waiwai.

ʻO ka pauka polimer hiki ke hoʻihoʻi ʻia (RPP):

1. Wehewehe:

• ʻO ka Redispersible Polymer Powder he pauka keʻokeʻo keʻokeʻo i hui pū ʻia me nā mea hoʻohui a me nā mea hoʻopihapiha.

2. Huina:

• Hana ʻia me nā emulsions polymer (e like me vinyl acetate-ethylene copolymers) i hoʻomaloʻo ʻia e lilo i pauka.

3. Waiwai:

• Hiki i ka wai hou: Hiki i ka RPP ke hoʻokaʻawale i ka wai e hana i kahi kiʻiʻoniʻoni, e like me ka emulsion polymer kumu.
• Hoʻopili: Hāʻawi i ka pili a me ka maʻalahi i nā morta, sima, a me nā mea hana ʻē aʻe.
• Hoʻokumu kiʻiʻoniʻoni: Hiki ke hana i kahi kiʻiʻoniʻoni cohesive a maʻalahi i ka maloʻo.

4. Nā noi:

• Ka Hana Hana Hana: Hoʻohana ʻia i loko o nā tile adhesives, nā mea hoʻoheheʻe sima, a me nā mea hoʻohui ponoʻī no ka hoʻomaikaʻi ʻana i ka adhesion, ka maʻalahi, a me ka pale wai.
• Mortars and Renders: Hoʻonui i nā waiwai e like me ka hana, ka lōʻihi, a me ka pili.
• Nā Pena a me nā Kāpena: Hiki ke hoʻohana ʻia i nā pena pena a me nā uhi no ka hoʻomaikaʻi ʻana a me ka hoʻopili ʻana.

Nā ʻokoʻa:

• Hiki ke hoʻoheheʻe:
  • Hiki ke hoʻoheheʻe ʻia nā cellulose eter i ka wai.
  • ʻAʻole hiki ke hoʻoheheʻe ʻia ka RPP i ka wai akā hiki ke hoʻopuehu hou i ka wai e hana i kahi kiʻiʻoniʻoni.
• Nā ʻāpana noi:
  • Loaʻa i nā cellulose ethers nā noi like ʻole i ka lāʻau lapaʻau, ka meaʻai, a me ka mālama pilikino, ma kahi o ke kūkulu ʻana.
  • Hoʻohana nui ʻia ʻo RPP i ka ʻoihana kūkulu no ka hoʻomaikaʻi ʻana i nā waiwai o ka mortar, sima, a me nā uhi.
• Huina Kemika:
  • Loaʻa ka cellulose ethers mai ka cellulose, kahi polymer maoli.
  • Hana ʻia ʻo RPP mai nā emulsion polymer synthetic.

I ka hōʻuluʻulu ʻana, ʻoiai ʻo cellulose ethers he mau polymers wai me nā noi like ʻole, ʻo Redispersible Polymer Powder he pauka wai ʻole i hoʻohana nui ʻia i ka ʻoihana hana e hoʻonui ai i nā waiwai o nā mea hana. Hāʻawi lākou i nā kumu like ʻole a koho ʻia ma muli o nā koi noi kikoʻī.
