Kaʻina hana hana a me ka hana o ka hydryethyl cellulouse (hec)

I. Ka Palapala

ʻO Hydroxythyl Cellouse (hec) kahi potic-inic wai-inic ākea ākea, nā lole, ke kūkuluʻana i kēlā me kēia lā. Loaʻaʻo Hec e ka hoʻololiʻana i ka chemila o ka cellouse, a me kona mau waiwai a me nā hoʻohanaʻana e hoʻoholoʻia e nā mollul sellulose.

II. Pūhala Hana

ʻO ke kaʻina hana hana o Hec nui loa e pili ana i nā hana e pili ana i kēia: Cellilose ethelificalificalification, holoi, holoi, hoʻomaloʻo, e hoʻomaʻemaʻe ana. ʻO kēia ka mea i hōʻikeʻia i kēlā me kēia papa kuhikuhi:

Hoʻokomoʻiaʻo Cellulouse

Ua mālama muaʻiaʻo Cellouse me Alkali e hana i nā Alkali Celloul (Cellulose Alkali). Hoʻohana pinepineʻia kēia kaʻina hana i kahi reactors, e hoʻohana ana i ka hopena sodium hydroxide e hana i ka cellulose kūlohelohe e hana ai i ka cellulose. ʻO ka hopena o keʻano e like me kēia:

Cpp-oh + naoh → Oon-Old-Old-OLD-O-NaHLell-O-NaO + Na Keiki-Na-na-na-NaH

A laila,ʻo Alkali cellous e hana me ka olleyne olleyne oxide e hana i ka cellulose hydroesethyl cellulose. Ua laweʻia ka hopena ma lalo o ke kiʻekiʻe kiʻekiʻe, maʻamau 30-100 ° C, a me keʻano kiko'ī penei:

Cell-O-Na-Ch2Rell2O → cAll-O-Ch2ch2Ohcell-O-cell 2ch 2H

Pono kēiaʻano i ka mana kūpono o ka mahana, ke kaomi a me ka nui o ka overlene o Everlene i hoʻohuiʻia e hōʻoia i kaʻano kūpono a me ka maikaʻi o ka huahana.

Ka holoi

ʻO ka hopena o ka hopena o ka mea kanu hec maʻamau e like me ka Alkali, Evertenene oxde a me nā huahana'ē aʻe e laweʻia e ka wai wai ʻO ka nui o ka wai e koiʻia i ka wā holoi holoi wai, a me ka mea kūʻai aku ma hope o ka holoiʻana i ka holoiʻana a hoʻokuʻuʻia.

Hilahila

ʻO ka'ōpū ma hope o ka holoiʻana i ka holoiʻana, maʻamau ma ka maʻamau recouum filtration a iʻole ka hoʻokaʻawaleʻana i ka hoʻokaʻawaleʻana i kaʻike.

Haunaele

Hoʻopiliʻia ka hec dehydted hec, maʻamau ma ka holoiʻana i ka maloʻo a iʻole ka uila. Pono ke kauʻana a me ka manawa e kāohiʻia i ka wā o ke kaʻina maloʻo e pale ai i keʻano kiʻekiʻe o ka wela a iʻole agglomeration paha.

Kūhā

Pono ka block ic pale i ka lepo a ua hana i ka neʻeʻana i kahi'āpana o ka neʻeʻana i kahi papa hana maʻamau, aʻo ka hopena hope loa a iʻole nā ​​huahana granur a iʻole nā ​​huahana granur.

III. Nā hiʻohiʻona hiʻohiʻona

Wai wai wai

Ua loaʻa iā Hec ka waiʻona wai maikaʻi a hiki ke hoʻopau koke i ka wai anuanu a me ka wai wela e hana ai i kahi'ōnaehana transparent a iʻole ka hoʻololiʻana. Hanaʻia kēia waiwai hemolele i hoʻohana nuiʻia e like me ka shaickener a me ka stabilizer a me ke stabilizer ma nā lole a me nā huahana o nā mea i kēlā me kēia lā.

Hiʻi

Hōʻikeʻo Hec i ka hopena nui o ka nui o nā kahe momona i loko o ka hopenaʻala, a me kona mau haole, a hoʻonui kona mau kiʻekiʻe me ka hoʻonuiʻia o ke kaumaha Molecu-o ke kaupaona Molecular. Hoʻomaopopo kēia waiwai waiwai ke hoʻokani i kahi roole ma keʻano he nui a me ka ho'ōlaʻana i ka wai.

Rheology

Hec aqueous solution he mau mea waiwai likeʻole, a me kona mau koho i hoʻololiʻia me ka loli o ka helu shear, e hōʻike ana i kaʻili a iʻole ka pseudoplaticty. Hiki i kēia waiwai Rheological e hoʻoponopono i keʻano a me ke kūkuluʻana i ka hana a me ke kūkuluʻana i nā kāhiko a me ka ailaʻailaʻailaʻaila.

Emullification a me ka hoʻokuʻuʻana

Hec maikaʻiʻo Hec a me nā mea hoʻopiʻi, hiki ke hoʻopaʻaʻia i nā'āpana i hoʻokuʻuʻia a iʻole nā ​​mea i hoʻopaʻaʻia i ka hoʻopiʻiʻana a me nā kiʻi. No laila, ua hoʻohana pinepineʻiaʻo Hec i nā huahana e like me nā mea e like me nā coatings a me nā mea i hoʻopauʻia.

Biodegradabilita

ʻO Hec kahi clivative kūlohelohe maikaʻi me ka biodegratablibveblib,ʻaʻole i hōʻeha i ke kaiapuni, a hui i nā koi o ka pale o ke kaiāulu.

IV. Kahua noi

Nā pāpale

I nā lole wai-wai e hoʻohanaʻia, ua hoʻohanaʻiaʻo hec ma keʻano he skickener a me ka stabilizer e hoʻomaikaʻi i ka uluʻana o ka wai.

Kūkulu hoʻi

I loko o nā mea waiwai, ua hoʻohanaʻiaʻo Hec i ka mokuahi o ka mokuahi e pili ana i ke kauʻana a me ka hoʻokomoʻana i ka hana hana a me ka hoʻomauʻana o ka wai.

ʻO nā Keʻena o kēlā me kēia lā

I loko o nā pale, shampoos, a me nā niho niho, ua hoʻohanaʻiaʻo hec e like me ka shaickener a me ka stabilizer e hoʻomaikaʻi i ka huahana. 

'Iniena? 【MAPELESDING?

I ka hanaʻana o ka aila a me nā wai kīwī, hoʻohanaʻia e hoʻoponopono i keʻano o ka rheology a me nā mea hoʻopiʻi hoʻopiʻi a hoʻomaikaʻi i ka pono o ka dhellinging a palekana.

Ka pepa hoʻohou

I ke kaʻina pepa, ua hoʻohanaʻiaʻo Hec e mālama i ka palapul pludity a hoʻomaikaʻi i ka lole a me nāʻano o ka pepa.

Ua hoʻohana nuiʻia ka maʻi maʻi hydrolsethyl ʻO kāna kaʻina hana e pili ana i ke kaʻina hana. Ma o nāʻanuʻu o nā cellouse, holoi, ka hanaʻana, e maloʻo ana, e mākaukau nā huahana maikaʻi a me ka maikaʻi. I ka wā e hiki mai ai, me ka hoʻomaikaʻiʻana i nā pono palekana palekana kaiāulu a me ka holomua o kaʻenehana, e pālahalahaʻia nā mea pāʻani o Hec.
