Nā waiwai o ka Methyl Cellulose
ʻO ka Methyl cellulose (MC) he cellulose ether i loaʻa ka nui o nā noi i nā ʻoihana like ʻole, me ka meaʻai, nā lāʻau lapaʻau, a me ke kūkulu ʻana. Aia kekahi o nā waiwai o MC:
- Solubility: Hiki ke hoʻoheheʻe ʻia ka MC i ka wai a hiki ke hana i kahi hopena maʻemaʻe a paʻa i ka wela lumi. Hiki ke hoʻoheheʻe ʻia i loko o kekahi mau mea hoʻoheheʻe kūlohelohe, e like me ka ethanol a me ka methanol.
- Viscosity: ʻO ka viscosity o nā hoʻonā MC e pili ana i nā kumu he nui, me ke ʻano o ka hoʻololi ʻana, ke kaumaha molekala, a me ka neʻe ʻana o ka hopena MC. Hōʻike nā haʻina MC i ke ʻano kahe kahe ʻole o Newtonian, ʻo ia hoʻi ka loli ʻana o ka viscosity me ka shear rate.
- Hana kiʻiʻoniʻoni: Hiki i ka MC ke hana i kahi kiʻiʻoniʻoni ke hoʻoheheʻe ʻia i ka wai a maloʻo. ʻO ke kiʻiʻoniʻoni i hoʻokumu ʻia e MC he maʻalahi, akaka, a he mau mea pale maikaʻi.
- ʻO ke kūpaʻa wela: He kūpaʻa wela maikaʻi ka MC a hiki ke pale i nā mahana a hiki i 200 ° C me ka ʻole o ka hōʻino nui.
- Hoʻohālikelike: Ua kūpono ʻo MC me nā mea ʻē aʻe he nui, me nā cellulose ethers, starch, a me nā protein.
- Hydrophilicity: He hydrophilic nui ka MC, ʻo ia hoʻi he pili ikaika i ka wai. Hoʻohana ʻia kēia waiwai i ka MC i nā mea hoʻohālikelike kahi mea nui e mālama ai i ka wai, e like me ka meaʻai a me nā huahana mālama pilikino.
ʻO ka holoʻokoʻa, ʻo nā waiwai o MC e lilo ia i mea maʻalahi i hiki ke hoʻohana ʻia i nā noi like ʻole.
