Synthesis a me nā hiʻohiʻona huahana o ka hydrosypoppropplolose

Hydrexypropropsl hydrolcellse (HPMC)ʻo ia kahi o nā eter cellouse eter i hanaʻia mai loko mai o ka cellouse kūlohelohe ma o ka hoʻololiʻana i keʻano. Ua hoʻohana nuiʻia ia ma nā papa o ke kūkuluʻana, nā lāʻau lapaʻau, meaʻai a me nā cosmetics. ʻO kāna kaʻina hana synthesis a me nā hiʻohiʻona huahana e hāʻawi i ka hana kūʻokoʻa a hiki ke hoʻokō i nāʻano hana likeʻole.

1. Synthesis of hydroxyproopplolose

ʻO ka hoʻomākaukauʻana o ka kimacell®hpmc e hoʻohana i ka collul kūlohelohe maoli e like me ka mea hana a me keʻano o ka hana a me keʻano o ka alkali. ʻO ke kaʻina hana synthesis e pili ana i nā pae aʻe:

Alkalization o Cellulose

E like me nā mea e like me nā mea e like me ka pulp pulp a iʻole ka lāʻau lāʻau lapaʻau a me ka ikaika e hana ai i kahi mahana a me ka ikaika alkali. ʻO ke kaʻina hana alkalization e hoʻonui i ka kaulahao Molecular a hoʻonui i kona hanaʻana me ka mea e hoʻonui ai i ka mea e hoʻopili ai.

ʻO ka hoʻohālikelikeʻana

Ua hanaʻiaʻo Alkali Cellouse me Formaldehyde a me Prosplene Glycol Propylene Oxde e hana i ka mydrocrelllulol. I ka wā o ka hopena,ʻo ka hanaʻana a me ka hydroxyprobial e hana i ka manawa manawaleʻa

ʻO ka heleʻana a me ka holoiʻana

Ma hope o ka pauʻana o ka hopena, hoʻohuiʻia kahi hopena acidic e hana i keʻano kūpono, a laila holoiʻia me ka wai e lawe i ka wai

Ka maloʻo a me ka crushing

Ua maloʻo ka hpmc i kahi kiko'ī haʻahaʻa haʻahaʻa a wāwahi i ka pauka e loaʻa ai ka huahana hope loa. Hiki ke hoʻoponoponoʻia ka nui o ka'āpana o ka huahana e like me nā koi noi.

2.ʻO nā hiʻohiʻona huahana o ka hydroxyproopplolose

Loaʻa iā HPMC i nā waiwai pilikino a me nā mea kūʻai aku, e hana maikaʻi ana i nāʻano noi.

Maikaʻi loa wai

Hiki ke hoʻolōʻihiʻiaʻo HPMC i ka wai anuanu e hana i kahi'ōmaʻomaʻo kohu transparent, aʻaʻole i piliʻia kāna kūleʻa e ka paʻakikī o ka wai. ʻO HPMC ka nui o ka wai wela, akā hiki iā ia ke hoʻihoʻi i ka nohona ma hope o ka pauʻana o ka wai. Ua kūpono kēia waiwai i nā hiʻohiʻona e pono ai i ka hana getion thermal.

Nā waiwai o nā mea kanu

ʻO HPMC kahi waiwaiʻole me ka ponoʻole o nā alenian maikaʻi i nā maʻi, alkaliis a me nā paʻakai, a hiki ke noho paʻa i lalo o nā kūlana'ē aʻe.

ʻO nā waiwai maikaʻi a me nā waiwai

ʻO ka hopena kūpono o ka hpmc i loaʻa i ka hopena nui, a hoʻonui kona mau hōʻailona me ka hoʻonui o ka loaʻaʻana a me ke kaumaha molela. ʻO kāna mau'ōhua a me kāna mau waiwai kiʻi kiʻi e hana ai e hana maikaʻi i nā lole a me nā adhesives.

ʻO nā waiwai Grouction Thermal Greak

ʻO ka hpmc solution folt i lalo o keʻano he geversible gevers i ka hoʻomehanaʻana a hoʻihoʻi hou i ke kūlana wai ma hope o ka hoʻomaʻemaʻe. Hoʻohana nuiʻia kēia waiwai o keʻano o keʻano ma nā hale hana

Non-toxic a me biocompatible

Mai ka HPMC i loaʻa mai i ka cellulose kūlohelohe a loaʻa i ka biocompatibility a me ka palekana, ua hoʻohana nuiʻia ma nā papa hana lāʻau lapaʻau e pili ana i nā papa hana lāʻau lapaʻau.

Hoʻololi e hoʻoponopono i ka hana

Hiki ke hoʻoponoponoʻia ka pae o ka sciody (ds a me ms) o ko ka kimacell®Hpmc i hiki ke hoʻoponoponoʻia, e hoʻololi ana i nā koina o nā noi likeʻole.

Hpmc hiki ke hoʻohanaʻia e like me ka mea i hōʻemiʻia a me ka nui o ka momi ma ka papa hana, e like me ka mea e hoʻokele ai i ka lāʻau lapaʻau, a ma keʻano emulsifier i kaʻoihana meaʻai. Me ka holomua o ka'ōmaʻomaʻo'ōmaʻomaʻo a me ka hoʻomohalaʻana i ka hoʻomohalaʻana, a me ka hoʻomohala haʻahaʻa haʻahaʻa o ka hpmc no ka noiʻiʻana i ka wā e hiki mai ana.

Ua liloʻo HydroxyPropsLlElfloplose i lilo i mea waiwai a me nā mea nui i kaʻoihana a me nā ola o kēlā me kēia lā me kāna hana maikaʻi a me ka hanaʻole.
