ʻO ka Methylcellulose kahi derivative cellulose maʻamau i hoʻohana nui ʻia i ka lāʻau lapaʻau, ka meaʻai a me ka ʻoihana. He polymer hiki ke hoʻoheheʻe ʻia i ka wai i hana nui ʻia me ka cellulose mea kanu maoli e ka hoʻololi kemika, a he nui nā waiwai kūʻokoʻa, e like me ka mānoanoa, gelling, suspension, film-forming and water retention.
Nā hiʻohiʻona a me ka hoʻohana ʻana o ka methylcellulose
Mānoanoa a gelling agent: I ka ʻoihana meaʻai, hoʻohana pinepine ʻia ka methylcellulose ma ke ʻano he mānoanoa a me ka gelling agent e kōkua i ka hoʻomaikaʻi ʻana i ke ʻano a me ka ʻono o ka huahana. No ka laʻana, i loko o nā huahana e like me ka ice cream, jam a me ka pāpale salakeke, hiki i ka methylcellulose ke hāʻawi i ka viscosity maikaʻi a hoʻomaikaʻi i ka paʻa o ka huahana.
Nā mea lawe lāʻau a me nā mea kōkua: I ka ʻoihana lāʻau lapaʻau, hoʻohana pinepine ʻia ka methylcellulose ma ke ʻano he lāʻau lapaʻau, e like me ka mea hoʻopili a me ka mea hoʻopihapiha no nā papa. Hiki ke hoʻohana ʻia ma ke ʻano he lāʻau hoʻokuʻu hoʻokuʻu i ka lāʻau e kāohi i ka hoʻokuʻu ʻana o ka lāʻau lapaʻau a hōʻoia i ka paʻa a me ka lōʻihi o ka hopena lāʻau.
Hoʻohana i nā mea hana hale: Ma ke kahua o nā mea kūkulu hale, hoʻohana ʻia ka methylcellulose ma ke ʻano he mānoanoa a me ka mea mālama wai i ka sima, gypsum a me nā uhi e hoʻomaikaʻi ai i ka hana hana a me ka lōʻihi o ka mea.
ʻO ka ʻokoʻa ma waena o ka methylcellulose a me nā mea antifoaming
ʻO nā antifoaming agents kahi papa o nā kemika i hoʻohana ʻia e hoʻopau a hoʻopau paha i nā ʻōpū i loko o ka wai, a loaʻa pinepine ʻia i ka hoʻoili ʻana i nā meaʻai, nā lāʻau lapaʻau, nā mea hoʻonaninani, ka hana pepa, nā kemika, a me ka mālama wai. Hoʻohana pinepine ʻia nā antifoaming agents ma ka hoʻemi ʻana i ka ʻili o ka ʻili o ka wai e pale ai i ka hana ʻana o ka huʻa, a i ʻole ma ka hāpai ʻana i ka hāʻule wikiwiki ʻana o ka ʻūhā i hana ʻia. ʻO nā mea hana antifoaming maʻamau ka aila silicone, polyethers, fatty acid esters, a me kekahi mau mea paʻa, e like me ka silicon dioxide.
Eia naʻe, ʻaʻole ʻo methylcellulose kahi mea antifoaming ma ke ʻano. ʻOiai hiki i ka methylcellulose ke hana i kahi hopena viscous ke hoʻoheheʻe ʻia i loko o ka wai, a hiki i ka viscosity o kēia hopena ke hoʻopili i ka hoʻokumu ʻana o ka huʻa i kekahi mau hihia, ʻaʻole ia i nā waiwai o ka ʻili o nā mea antifoaming maʻamau. I nā huaʻōlelo ʻē aʻe, ʻo ka hana nui o ka methylcellulose ʻo ia ka hana ma ke ʻano he mānoanoa, gelling agent, suspending agent, a me nā mea ʻē aʻe, ma mua o ka hoʻohana pono ʻia ʻana e hoʻopau a hoʻopau i ka pua.
Hiki ke huikau a me nā hihia kūikawā
ʻOiai ʻaʻole he antifoaming agent ka methylcellulose, i loko o kekahi mau mea kikoʻī a i ʻole nā huahana, hiki ke hoʻopilikia i ke ʻano o ka huʻa ma muli o kona hopena mānoanoa a me nā ʻano hoʻonā. No ka laʻana, i kekahi mau meaʻai a i ʻole nā lāʻau lapaʻau, hiki i ka viscosity kiʻekiʻe o ka methylcellulose ke kaupalena i ka hoʻokumu ʻana o nā ʻōpū a i ʻole e hoʻoheheʻe ʻia nā ʻōpū i hana ʻia. Eia naʻe, ʻaʻole hiki i kēia hopena ke hoʻokaʻawale ʻia ma ke ʻano he antifoaming agent no ka mea he ʻokoʻa loa kona ʻano hana nui mai ke ʻano kemika a me ke ʻano o ka hana o nā antifoaming agents.
ʻO ka Methylcellulose he mea hoʻohana nui i ka cellulose derivative me nā hana he nui, akā ʻaʻole ia i manaʻo ʻia he antifoaming agent. ʻOiai he hopena paha ia i ka hana huāhuʻu i kekahi mau hihia kikoʻī, ʻaʻole kēia i hoʻohana nui ʻia a i ʻole ka hana o ka hana. Loaʻa i nā mea antifoaming nā hana maʻamau a me nā mana hoʻomalu o ka foam, ʻoiai ʻoi aku ka hoʻohana ʻana o ka methylcellulose no ka mānoanoa, gelling, suspension a me ka paʻa wai. No laila, i ka hoʻohana ʻana i ka methylcellulose, inā makemake ʻia kahi hopena antifoaming maʻemaʻe, pono e koho ʻia kahi mea antifoaming kūikawā no ka hoʻohana pū ʻana.
