ʻO nā hōʻailona nui e ana i ka maikaʻi o ka CMC ʻo ke degere o ka hoʻololi (DS) a me ka maʻemaʻe.ʻO ka maʻamau, ʻokoʻa nā waiwai o CMC inā ʻokoʻa ka DS;ʻoi aku ka kiʻekiʻe o ka hoʻololi ʻana, ʻoi aku ka maikaʻi o ka solubility, a ʻoi aku ka maikaʻi o ka ʻike a me ka paʻa o ka hopena.Wahi a nā hōʻike, ʻoi aku ka maikaʻi o ka transparency o CMC inā ʻo ke degere o ka hoʻololi ʻana he 0.7-1.2, a ʻo ka viscosity o kāna hoʻonā wai ka mea nui loa i ka wā o ka pH waiwai he 6-9.
I mea e hōʻoiaʻiʻo ai i kona maikaʻi, ma kahi o ke koho ʻana i ka mea etherifying agent, pono e noʻonoʻo ʻia kekahi mau mea e pili ana i ke kiʻekiʻe o ka hoʻololi ʻana a me ka maʻemaʻe, e like me ka pilina pili ma waena o ka alkali a me ka etherifying agent, ka manawa etherification, ka wai wai ʻōnaehana, ka mahana. , ka waiwai pH, ka hoʻonā ʻana a me ka paʻakai.
Hoʻohana nui ʻia ʻo Sodium carboxymethyl cellulose i ka ʻaila, meaʻai, lāʻau lapaʻau, textile, papermaking a me nā ʻoihana ʻē aʻe, no laila he mea nui loa e hoʻoponopono pololei i kona maʻemaʻe, a he ana hoʻi ia e hōʻoia ai i kona hopena hoʻohana, a laila, Pehea mākou e ʻike ai, honi, hoopa, a palu e hookolokolo i kona maemae?
1. ʻO ka sodium carboxymethyl cellulose me ka hoʻomaʻemaʻe kiʻekiʻe he kiʻekiʻe loa ka paʻa ʻana o ka wai, ka hoʻouna māmā maikaʻi, a ʻo kona kiʻekiʻe paʻa wai e like me 97%.
2. ʻO nā huahana me ka maʻemaʻe kiʻekiʻe ʻaʻole e honi i ka ʻala o ka ammonia, starch a me ka waiʻona, akā inā he haʻahaʻa haʻahaʻa, hiki iā lākou ke honi i nā ʻano ʻono like ʻole.
3. ʻO ka sodium carboxymethyl cellulose maʻemaʻe he fluffy visually, a he liʻiliʻi ka nui o ka nui,ʻo ka laulā: 0.3-0.4 / ml;ʻoi aku ka maikaʻi o ka hoʻoheheʻe ʻana o ka moekolohe, ʻoi aku ka kaumaha o ka lima, a he ʻokoʻa koʻikoʻi me ke ʻano kumu.
4. Hoʻohālikelike ʻia ka maʻiʻo chloride o CMC ma CL, ma hope o ke ana ʻana o ka maʻiʻo CL, hiki ke hoʻololi ʻia ka ʻike NaCl i CL%*1.65
Aia kekahi pilina ma waena o ka CMC content a me ka chloride, akā ʻaʻole nā mea āpau, aia nā mea haumia e like me ka sodium glycolate.Ma hope o ka ʻike ʻana i ka maʻemaʻe, hiki ke helu ʻia ka ʻike NaCl NaCl%=(100-purity)/1.5
Cl%=(100-maemae)/1.5/1.65
No laila, he ʻono paʻakai ikaika ka hua ʻōlelo alelo, e hōʻike ana ʻaʻole kiʻekiʻe ka maʻemaʻe.
I ka manawa like, ʻo ka sodium carboxymethyl cellulose maʻemaʻe kiʻekiʻe he kūlana fiber maʻamau, aʻo nā huahana haʻahaʻa haʻahaʻa he granular.Ke kūʻai ʻana i kahi huahana, pono ʻoe e aʻo i kekahi mau ala maʻalahi o ka ʻike.Eia kekahi, pono ʻoe e koho i kahi mea hana me ka inoa maikaʻi, i ʻoi aku ka maikaʻi o ka huahana.
Ka manawa hoʻouna: Nov-11-2022
