Chemistry o ka metholoud ™ celllouse

Hui pū™ He hōʻailona hōʻailona o nā leka uila i hanaʻia e Dow. Ua loaʻa i kēia mau leka uila e loaʻa mai nā mea elima, kahi polyom kūlohelohe maoli i loaʻa i nā paia lāʻau. ʻO ka chemistry o ka methoced ™ e pili ana i ka hoʻololiʻana o ka cellouse ma o nā ethelification o nā meaʻala. ʻO nāʻano mua o ka method e loaʻa ana i ka hydroxyproopsllllfall mydroxlyl middlelcell Eia kekahi overview ākea o ka chemistry o ka methoced ™:

1. Hydroxyprockl middlelcellse (hpmc):

• Kūlana:
  • ʻO HPMC kahi wai wai-wai-wai me nā cosithentsʻelua: hydroxyprooppyl (hp) a me nā mi).
  • Hōʻike nā pūʻulu hydroxyproopyll i ka hana hydrophil
  • Hāʻawi ka huiʻana i nā hui Mithll
• KA MEA O OTHEROTIFILINA:
  • Ua hanaʻiaʻo HPMC ma o ka hoʻonuiʻana i ka cellulose me ka propplene propide (no nā hui hydroxyproopyl) a me Mithyl chloride).
  • Mālamaʻia nā kūlana kūpono e hoʻokō ai i ka pae i makemakeʻia o ka spelltient (ds) no nā hui hydroxyproopsl a me nā hui miyyl.
• Nā waiwai:
  • Hōʻikeʻo Hpmc i nā lako wai momona, nā kiʻi kiʻi kiʻi, a hiki ke hāʻawi i ka hoʻokuʻu i mālamaʻia i nā noi pharmaceturical.
  • ʻO ke kiʻekiʻe o keʻano o keʻano o keʻano he ciscosity o ka poscoity o ka polymer, ka nui o ka wai, a me nā waiwai'ē aʻe.

2.

• Kūlana:
  • Mc he celllouse cellouse me ka cobritunts othyl.
  • Ua like ia me HPMC akā ua nele i nā hui hydroxyproopsl.
• KA MEA O OTHEROTIFILINA:
  • Ua hanaʻiaʻo MC e ka eterifying cellouse me ka mloride.
  • Hoʻoholoʻia nā kūlana kūpono e hoʻokō ai i ke kiʻekiʻe o nā mea i makemakeʻia.
• Nā waiwai:
  • MC ka wai wai-wai a he noi noi i na halekuai o na haumana, hana, a me na hana kaa.
  • Ua hoʻohanaʻia ia he mea nāna e hoʻopili, hili, a stablizer.

3, nā waiwai maʻamau:

• Wai wai wai
• ʻO ka hoʻokumu kiʻi kiʻi: hiki iā lākou ke hana i nā kiʻiʻoniʻoni a me nā kiʻiʻoniʻoni, e hana ana iā lākou i mea kūpono i nā noi likeʻole.
• ʻO SWickening: Metopled ™ celllouse e hana ana i nā mea hana e like me nā mea nui e like me nā mea he nui o nā hopena o nā hopena.

4. Nā noi:

• Nā Pharmaceutitical: i hoʻohanaʻia ma nā lole papaʻaina, nā mea paʻa, a me nāʻano hana i hoʻopaʻaʻia.
• Hana i: hana i loko o nā waimaka, nā mea a me nā mea hana, a me nā mea'ē aʻe.
• Meaʻai: hoʻohanaʻia e like me nā mea nui a me nā stabilizers i nā huahana meaʻai.
• ʻO ka mālama pilikino:ʻikeʻia i loko o nā cosmetics, shampoos, a me nā mea mālama pilikino'ē aʻe.

ʻO ka Chemistry o ka metholoud ™ cellulose e nā mea e hana ai iā lākou e pili ana i nā waiwai o nā mea e pono ai. Hiki ke hoʻopiliʻia nā waiwai kiko'ī ma o ka hoʻoponoponoʻana i ke kiʻekiʻe o keʻano a me nā mea hana'ē aʻe.
