Kaʻina no ka hanaʻana o ka hanaʻana o ka mellouse cellounuse eter

Ka hana aʻO Mathyl celllouse etherpili i ka hoʻololiʻana i ka cemikina o ka cellouse ma o nā mea e hoʻohuli ai. ʻO MillLulse cellulouse (mc) kahi wai wai-wai-wai-wai-i hoʻohana nuiʻia ma nāʻano likeʻole. Eia kekahi overview maʻamau o ke kaʻina hana no ka hanaʻana o ka mathyl celliete eter:

1. E koho i ke kumu o ke kumu kūʻai:

• Hoʻomaka ke kaʻina hana me ke kohoʻana o ke kumu o ke kumu o ke celoulose Kohoʻia ke kumu o ka cellouse ma luna o nāʻano i makemakeʻia o ka huahana mollunuse hope loa.

2.

• ʻO ke kumu kūʻai koho koho i kohoʻia, he kaʻina hana e wāwahi i lalo i nā fibers i kahiʻanoʻoi aku ka nui. Hiki ke loaʻa i ka pulpping ma o nā hana mechanical a iʻole nāʻano lāʻau.

3

• ʻO ka celllud cellouse e hanaʻia e ka mālamaʻana iā ia me kahi hopena alkaline. Ke hana nei kēia i nā pahuhopu i ka holoiʻana i nā fibers cellouse, e hana hou ana iā lākou i ka hopena o keʻano o ka hopena o ka nui o ka nui.

4. ETEROTIOTIFORE RAME:

• ʻO ka mea i hanaʻia i loko o ka cellulose i loko o ka hoʻohuihuiʻana, kahi o nā hui eter, i kēia hihia, nā hui potdroxyl
• Ua pili keʻano o ka ethenafication e hoʻohana i ka hoʻohanaʻana i nā mea a me nā mea e like me ka sodium hydroxide a me ka mityll chlofate. ʻO nā kūlanaʻano, e pili ana i ka mahana, ka hoʻowalewale, a me ka manawa hopena, e mālama ponoʻia e hoʻokō i ke kiʻekiʻe o ka hoʻokaeʻana (DS).

5..

• Ma hope o ka hopena o ka ethetification Laweʻia nā hana holoi ma hope e hoʻopau ai i ka hoʻopauʻana i nā ceffical centual a me nā haumia.

6.

• Ka hoʻomaʻemaʻeʻia ka hoʻomaʻemaʻe a me ka minifladd cellouse e loaʻa i ka fellow mollul hope loa ma keʻano he nui a iʻole nā ​​granuna.

7.

• ʻO nāʻano hana likeʻole, e komo pū me nā mea e pili ana i ka nukle magnec ʻO ke kiʻekiʻe o ka hoʻololiʻana (DS) kahi hōʻailona koʻikoʻi i hōʻikeʻia i ka wā hana.

8. Hana a me ke kauʻana:

• ʻO ke keleponaʻo Mathyl Cellulose eter i hanaʻia i nā helu likeʻole e hoʻokō i nā koi kiko'ī o nā noi likeʻole. Hiki paha i nā māka likeʻole ma ko lākou mau viscosity, ka nui o ka'āpana, a me nā waiwai'ē aʻe.
• Hoʻopiliʻia nā huahana hope loa no ka hoʻokaʻawaleʻana.

He mea nui ia e hoʻomaopopo i nā kūlana kūikawā a me nā uku i hoʻohanaʻia ma keʻano o keʻano e pili ana i nā huahana proprietary a me nā mea i makemakeʻia e nā mea kūʻai aku. Loaʻa i nā keleponaʻo Mathylse i nā noi meaʻai ma kaʻoihana meaʻai, nā hale pule, a me nā'āpana'ē aʻe ma muli o kāna mau mea hana-sollability
