Pehea e hoʻoholo ai i ka maikaʻi o ka cellulose mai ka lehu o ka hydroxypropyl methylcellulose ma hope o ka puhi ʻana

ʻO ka mea mua, pono mākou e hoʻomaopopo i ka lehu:

01. Ua kapa ʻia hoʻi ka ʻike lehu he koena ahi, hiki ke hoʻomaopopo wale ʻia he haumia i loko o ka huahana.E hana maoli ia i ka wā o ka hana ʻana.Ma hope o ka puka ʻana o ka huahana mai ka reactor etherification, e komo ia i ka pahu neutralization.I loko o ka pahu neutralization, hoʻoponopono mua ʻia ka waiwai pH i kū ʻole, a laila hoʻohui ʻia ka wai wela no ka holoi ʻana.Hoʻohui ʻia ka wai wela , ʻO ka holoi ʻana, ʻoi aku ka nui o nā manawa holoi, ʻoi aku ka haʻahaʻa o ka lehu, a me ka hope.

02. Hōʻike ʻia ka nui o ka lehu i ka maʻemaʻe o ka cellulose, ʻoi aku ka kiʻekiʻe o ka maʻemaʻe, ʻoi aku ka liʻiliʻi o ka lehu ma hope o ke ahi!

A laila, e nānā kākou i ka ʻike i loaʻa iā mākou ma o ke kaʻina puhi o hydroxypropyl methylcellulose.

ʻO ka mua: ʻO ka liʻiliʻi o ka lehu, ʻoi aku ka kiʻekiʻe o ka maikaʻi

Nā mea hoʻoholo i ka nui o ke koena lehu:

(1) ʻO ka maikaʻi o ka cellulose maka (ka pulupulu hoʻomaʻemaʻe): ʻO ka mea maʻamau, ʻoi aku ka maikaʻi o ka maikaʻi o ka pulupulu hoʻomaʻemaʻe, ʻoi aku ka keʻokeʻo o ka cellulose i hana ʻia, ʻoi aku ka maikaʻi o ka lehu a me ka paʻa wai.

(2) Ka helu o nā manawa holoi: aia kekahi lepo a me nā haumia i loko o nā mea maka, ʻoi aku ka nui o ka holoi ʻana, ʻoi aku ka liʻiliʻi o ka lehu o ka huahana i hoʻopau ʻia ma hope o ke puhi ʻana.

(3) ʻO ka hoʻohui ʻana i nā mea liʻiliʻi i ka huahana i hoʻopau ʻia e hopena i ka nui o ka lehu ma hope o ke ahi ʻana

(4) ʻO ka hana maikaʻi ʻole i ka wā o ke kaʻina hana e hoʻopilikia pū i ka lehu o ka cellulose

(5) I mea e huikau ai ka hihio o na kanaka a pau, e hoonui kekahi mau mea hana i ka hoonui ahi ia ia, a aneane aohe lehu ma hope o ke ahi ana.ʻAi piha ia, akā ʻokoʻa loa ka waihoʻoluʻu ma hope o ke puhi ʻana me ka pauda maʻemaʻe.

ʻO ka lua: ka lōʻihi o ka manawa kuni:

ʻO ka cellulose me ka pae paʻa wai maikaʻi e wela no ka manawa lōʻihi, a ʻo ia hoʻi no ka haʻahaʻa paʻa wai.
