He aha ke kaʻina hana o ka methylcellulose?

ʻO Methylcellulose kahi ʻano polymer-based cellulose i hoʻohana ʻia i nā ʻano noi like ʻole, me ka meaʻai, nā lāʻau lapaʻau, a me nā mea hoʻonaninani. He pauda keʻokeʻo, ʻala ʻole, ʻono ʻole i hiki ke hoʻoheheʻe ʻia i ka wai anuanu a lilo i gel ke hoʻomehana ʻia. Hana ʻia ia ma ka mālama ʻana i ka cellulose me ka methyl chloride a me ka sodium hydroxide.

ʻO ke kaʻina hana o ka methylcellulose e pili ana i kekahi mau pae. ʻO ka hana mua ka loaʻa ʻana o ka mea maka, ʻo ia ka cellulose maʻamau. Hiki ke loaʻa ka cellulose mai nā kumu like ʻole, e like me ka pulp lāʻau, ka pulupulu, a me nā mea kanu ʻē aʻe. A laila mālama ʻia ka cellulose me ka methyl chloride a me ka sodium hydroxide e hana i ka polymer methylcellulose.

ʻO ka hana aʻe e hoʻomaʻemaʻe i ka methylcellulose. Hana ʻia kēia ma ka wehe ʻana i nā mea haumia e like me ka lignin, hemicellulose, a me nā mea ʻē aʻe e hiki ke hoʻopilikia i nā waiwai i makemake ʻia o ka methylcellulose. Hana ʻia kēia ma ka mālama ʻana i ka methylcellulose me ka waikawa a i ʻole ka alkali, a i ʻole ma ka hoʻohana ʻana i kahi kaʻina i kapa ʻia ʻo fractionation.

Ke hoʻomaʻemaʻe ʻia ka methylcellulose, a laila hoʻomaloʻo ʻia a lepo i lepo. A laila mākaukau kēia pauda no ka hoʻohana ʻana i nā ʻano hana like ʻole.

Hiki ke hoʻohana ʻia ka Methylcellulose ma ke ʻano he mea mānoanoa, emulsifier, stabilizer, a gelling agent. Hoʻohana ʻia ia i nā huahana meaʻai e like me ka ice cream, nā ʻaʻahu salakeke, a me nā ʻuala. I loko o nā lāʻau lapaʻau, hoʻohana ʻia ia ma ke ʻano he binder, suspending agent, a me ka uhi papa. I loko o nā mea hoʻonaninani, hoʻohana ʻia ia e like me ka mānoanoa, emulsifier, a me ka stabilizer.

ʻO ke kaʻina hana o ka methylcellulose he mea maʻalahi a maikaʻi. He ala maikaʻi loa ia e hana ai i nā ʻano huahana like ʻole me nā ʻano hoʻohana like ʻole. He mea palekana a ʻaʻohe mea ʻawaʻawa hiki ke hoʻohana ʻia i nā ʻano hana like ʻole.
