ʻO ke ala lehu no ke ana ʻana i ka Sodium Carboxymethyl Cellulose

ʻO ke ʻano lehu he hana maʻamau i hoʻohana ʻia no ka hoʻoholo ʻana i ka ʻike lehu o kahi mea, me ka sodium carboxymethyl cellulose (CMC). Eia ka papa kuhikuhi nui o ke ʻano hana lehu no ke ana ʻana i ka CMC:

1. Hoʻomākaukau Laʻana: E hoʻomaka ma ke kaupaona pololei ʻana i kahi laʻana o ka pauka sodium CMC. E hilinaʻi ka nui o ka laʻana i ka ʻike lehu i manaʻo ʻia a me ka naʻau o ke ʻano analytical.
2. Kaʻina Lehu: E kau i ka laʻana i kaupaona ʻia i loko o kahi kīʻaha i kaupaona mua ʻia a i ʻole ipu lehu. E puhi i ka ipuhao i loko o ka umu muffle a i ʻole ka mea hoʻomehana like ma kahi mahana i ʻōlelo ʻia, maʻamau ma waena o 500°C a me 600°C, no kahi manawa i koho mua ʻia, maʻamau he mau hola. Hoʻopau kēia kaʻina hana i nā mea kūlohelohe o ka hāpana, a waiho ʻia ka lehu inorganic.
3. ʻO ka hoʻoluʻu a me ke kaupaona: Ma hope o ka pau ʻana o ke kaʻina hana lehu, e ʻae i ka crucible e maʻalili i loko o kahi desiccator e pale ai i ka komo ʻana o ka wai. Ma hope o ka maʻalili ʻana, e kaupaona hou i ka pahu i loko o ke koena lehu. ʻO ka ʻokoʻa o ke kaumaha ma mua a ma hope o ka lehu e hōʻike ana i ka maʻi o ka lehu o ka hāpana sodium CMC.
4. Heluhelu: E helu i ka pākēneka o ka lehu i loko o ka hāpana sodium CMC me ka hoʻohana ʻana i kēia ʻano:
   $Maʻiʻo\; Lehu\; (\%)=(Ke\; kaupaona\; ʻana\; o\; ke\; kaumaha\; o\; ka\; Laʻana)\times 100$

   Maʻiʻo Lehu (%)=(Ke kaumaha o ka Laʻana/Ke kaumaha o ka lehu​)×100

5. E hana hou a hōʻoia: E hana hou i ke kaʻina hana lehu a me ka helu ʻana no nā laʻana he nui e hōʻoia i ka pololei a me ka hana hou ʻana. E hōʻoia i nā hopena ma ka hoʻohālikelike ʻana iā lākou me nā maʻamau i ʻike ʻia a i ʻole ma ka hana ʻana i nā ana like ʻole me ka hoʻohana ʻana i nā ala ʻē aʻe.
6. Noʻonoʻo: I ka hana ʻana i ka lehu no ka sodium CMC, pono ia e hōʻoia i ka hoʻopau piha ʻana o nā ʻāpana organik me ka wela ʻole, hiki ke alakaʻi i ka decomposition a i ʻole volatilization o nā ʻāpana inorganic. Eia hou, he mea koʻikoʻi ka mālama pono ʻana a me ka mālama ʻana i nā laʻana lehu i mea e pale ai i ka hoʻohaumia ʻana a me ka hōʻoia ʻana i ke ana pololei ʻana o ka ʻike lehu.

Hāʻawi ke ala lehu i kahi ala hilinaʻi e ana i ka nui o ka lehu o ka sodium carboxymethyl cellulose, e ʻae ai i ka mana maikaʻi a me ka hoʻokō ʻana i nā koi hoʻoponopono i nā ʻoihana like ʻole, me ka meaʻai, nā lāʻau lapaʻau, a me nā mea hoʻonaninani.
