Te whakamahinga o te konutai carboxymethyl cellulose i roto i te wai keri

Ko te konutai carboxymethyl cellulose (CMC-Na te whakarapopototanga) he matū pūmua wairewa-wai nui, ā, e whakamahia whānuitia ana i roto i te wai keri hinu. Nā ōna āhuatanga ahurei he wāhanga nui tēnei i roto i te pūnaha wai keri.

1. Ngā āhuatanga taketake o te konutai carboxymethyl cellulose

Ko te konutai carboxymethyl cellulose he etera cellulose anionic i hangaia e te cellulose i muri i te maimoatanga alkali me te waikawa chloroacetic. Kei roto i tōna hanganga ngota he maha o ngā rōpū carboxymethyl, e pai ai te wairewa me te pumau i roto i te wai. Ka taea e te CMC-Na te hanga i tētahi otinga matotoru teitei i roto i te wai, me ngā āhuatanga matotoru, pumau me te hanga kiriata.

2. Te whakamahinga o te konutai carboxymethyl cellulose i roto i te wai keri

Whakamātotoru

Ka whakamahia te CMC-Na hei whakamātotoru i roto i te wai keri. Ko tana mahi matua he whakanui ake i te matotoru o te wai keri me te whakarei ake i tōna kaha ki te kawe i ngā tapahi toka me ngā tapahi keri. Mā te matotoru tika o te wai keri ka taea te ārai i te hinga o te pakitara o te poka, me te pupuri i te pumau o te poka.

Kaiwhakaiti i te ngaronga wai

I te wā e keri ana, ka uru te wai keri ki roto i ngā pūwero o te hanganga, ka ngaro te wai i roto i te wai keri, ka moumou noa i te wai keri, engari ka hinga pea te pakitara o te poka me te kino o te puna wai. Hei whakaiti i te ngaronga wai, ka taea e te CMC-Na te hanga i tētahi keke tātari matotoru ki runga i te pakitara o te poka, ka whakaiti i te ngaronga tātari o te wai keri me te tiaki i te hanganga me te pakitara o te poka.

hinu whakahinuhinu

I te wā e keri ana, ka nui te wera e puta mai i te waku i waenga i te mata o te keri me te pakitara o te puna, ka nui ake te pakaru o te taputapu keri. Mā te hinu whakahinuhinu o te CMC-Na ka āwhina i te whakaiti i te waku, te whakaiti i te pakaru o te taputapu keri, me te whakapai ake i te whai huatanga o te keri.

Kaiwhakaū

Tērā pea ka rere te wai keri, ka memeha rānei i raro i te pāmahana tiketike me te pēhanga tiketike, ā, ka ngaro tana mahi. He pai te pumau o te CMC-Na ki te wera me te ātete ki te tote, ā, ka taea e ia te pupuri i te pumau o te wai keri i raro i ngā āhuatanga uaua me te whakaroa i tōna roanga mahi.

3. Te tikanga mahi a te konutai carboxymethyl cellulose

Te whakatikatika i te matotoru

Kei roto i te hanganga ngota o te CMC-Na he maha ngā rōpū carboxymethyl, ka taea e rātou te hanga hononga hauwai i roto i te wai hei whakanui ake i te matotoru o te otinga. Mā te whakarerekē i te taumaha ngota me te taumata whakakapinga o te CMC-Na, ka taea te whakahaere i te matotoru o te wai keri kia tutuki ai ngā hiahia o ngā āhuatanga keri rerekē.

Whakahaere tātari

Ka taea e ngā ngota CMC-Na te hanga i tētahi hanganga whatunga toru-ahu i roto i te wai, ka taea ai te hanga i tētahi keke tātari matotoru ki runga i te pakitara o te puna, me te whakaiti i te ngaronga tātari o te wai keri. Ko te hanganga o te keke tātari ehara i te mea e whakawhirinaki ana ki te kukū o te CMC-Na anake, engari ki tōna taumaha ngota me te taumata whakakapinga.

Whakahinuhinu

Ka taea te mimiti i ngā ngota CMC-Na ki te mata o te mata keri me te pakitara o te puna ki roto i te wai hei hanga i tētahi kiriata whakahinuhinu, hei whakaiti hoki i te tauwehenga waku. Hei tāpiri, ka taea hoki e te CMC-Na te whakaiti ā-kore i te waku i waenga i te mata keri me te pakitara o te puna mā te whakarerekē i te matotoru o te wai keri.

Te pumau o te wera

Ka taea e te CMC-Na te pupuri i te pumau o tōna hanganga ngota i raro i ngā āhuatanga pāmahana teitei, ā, kāore e ngāwari ki te pirau wera. Nā te mea ka taea e ngā rōpū carboxyl i roto i ōna ngota te hanga hononga hauwai pumau me ngā ngota wai hei ātete i te kino pāmahana teitei. Hei tāpiri, he pai hoki te ātete tote o te CMC-Na, ā, ka taea te pupuri i tana mahi i roto i ngā hanganga tote. 

4. Ngā Tauira Whakamahinga o te Sodium Carboxymethyl Cellulose

I roto i te tukanga keri tūturu, he mea whakamiharo te pānga o te konutai carboxymethyl cellulose. Hei tauira, i roto i tētahi kaupapa keri poka hohonu, i whakamahia he pūnaha wai keri kei roto ko te CMC-Na hei whakahaere pai i te pumau me te ngaronga tātari o te poka, hei whakanui ake i te tere keri, hei whakaiti hoki i te utu keri. Hei tāpiri, he whānuitia hoki te whakamahinga o te CMC-Na i roto i te keri moana, ā, nā tōna ātete pai ki te tote ka pai ai tana mahi i roto i te taiao moana.

Ko te whakamahinga o te konutai carboxymethyl cellulose i roto i te wai keri e whai wāhi ana ki ngā āhuatanga e whā: te whakamātotoru, te whakaiti i te ngaronga o te wai, te whakahinuhinu me te whakau. Ko ōna āhuatanga ā-tinana me ā-matū ahurei e mea ana hei wāhanga nui i roto i te pūnaha wai keri. Mā te whanaketanga tonu o te hangarau keri, ka whānui ake ngā tūmanakohanga whakamahinga o te konutai carboxymethyl cellulose. I roto i ngā rangahau a meake nei, ka taea te whakapai ake i te hanganga ngota ngota me ngā tikanga whakarerekētanga o te CMC-Na kia pai ake ai tana mahi me te whakatutuki i ngā hiahia o ngā taiao keri uaua ake.
