Carboxymethyl cellulose (CMC), he matū whakaputa cellulose wairewa-wai teitei te mahi, he whānuitia ngā whakamahinga i roto i ngā waituhi tā, ngā penupenu pania, me ngā rauemi tākai. I te whanaketanga o te hangarau tā ki ngā tere teitei ake, te atawhai taiao, me te mamati, ko te CMC, me ōna āhuatanga whakamātotoru, hanga kiriata, marara, me te pupuri wai pai rawa atu, kei te noho hei tāpiri mahi nui mō te whakapai ake i te kounga tā.
- Te Tūranga Matua o te CMC i roto i ngā Pūnaha Tā
1.1. Te Whakamātotoru me te Whakahaere Rheological
He pānga matotoru nui tō te CMC, e whakahaere ana i te whanonga rheological o ngā waituhi, o ngā otinga paninga rānei. Ka pupuri i tētahi matotoru ina okioki te pūnaha, ā, ka whakaiti i te matotoru i raro i te kutikuti, ka whakapai ake i te rere. Mā tēnei āhuatanga rheological "pērā i te kirihou" ka āwhina i te whakawhiti pumau o te waituhi i te wā tā, ka karo i ngā raruraru pēnei i te tauhiuhi waituhi, te aho, te totohu rānei, ā, ka whakapai ake i te mārama me te ōrite o ngā rārangi kua tāia.
1.2. Ngā Pānga o te Mararatanga me te Whakapūmautanga
I roto i ngā waituhi tae, ka taea e te CMC te piri ki te mata o ngā matūriki tae, ka hanga he pānga aukati pumau, he pānga aukati pākawa rānei, ka whakapai ake i te mararatanga o te tae, ka whakaiti hoki i te whakakotahitanga o ngā matūriki. Ehara i te mea ka whakarei ake te pūnaha mararatanga tae pumau i te kaha o te tae me te kaha huna anake, engari ka roa ake hoki te ora o te waituhi.
1.3. Te Hanga Kiriata me te Whakapai Ake i te Piringa
I muri i te maroke, ka whakaatuhia e te CMC ngā āhuatanga hanga kiriata tino pai, ka hanga he paparanga piri ōrite ki runga i te pepa, i ngā mata kiriata rānei, ka whakarei ake i te hononga i waenga i te mangumangu me te papa, ka whakapai ake hoki i te ātete ki te pakū, te ātete ki te wai, me te roa o te mahi o te paparanga kua tāia.
1.4. Ngā Pānga Pupuri Makuku me te Ārai-Whakamaroke
I roto i ngā waituhi wai me te tānga flexographic, ka taea e te CMC te whakaiti i te tere maroke o te waituhi i runga i te pereti tā, i roto rānei i te pūnaha rokiroki waituhi, ka ārai i te aukati pereti me te whakapai ake i te pumau o te tā tonu.
- Ngā horopaki tono noa o te CMC i roto i te umanga tā
2.1. Ngā Pūnaha Waituhi Wai-ā-Wai
He nui ake te whakamahinga o te CMC i roto i ngā waituhi tānga gravure me te flexographic e hangai ana ki te wai, hei whakapai ake i te matotoru, te marara, me te pumau, me te whakarei ake i te kī o te ahua. Nā ōna āhuatanga pai mō te taiao me te kore-paitini, he mea pai ake tēnei hei whakakapi i ngā whakamātotoru hangai tuku iho.
2.2. Te Hanga Pepa Panipani me te Pepa Motuhake
I roto i ngā tukanga paninga mō te pepa paninga, te kāri mā, me te pepa ahurea, ka whakamahia te CMC hei here me te whakarerekē rheology, e whakatairanga ana i te hanganga kiriata ōrite, e whakapai ake ana i te maeneene o te pepa, te kanapa, me te āheinga tā. Ina koa i roto i ngā pepa kanapa-nui, ka taea e te CMC te whakapai ake i te tohatoha matūriki tae, ka hua ake he taipitopito mārama ake.
2.3. Ngā Waituhi Tānga Waituhi
I te whanaketanga o te hangarau inkjet, kei te piki haere te whakamahinga o te CMC i roto i ngā pūnaha waituhi inkjet wai:
Te whakahaere i te āhua me te horapa o te pata;
Te whakapai ake i te pumau o te tae;
Te whakaiti i te tere o te aukati i te pane tā.
Ka āwhina i te whakapai ake i te kounga whakaahua i ngā mara tino tika pērā i te tānga whakaahua me te tānga tapanga.
2.4. Ngā Rauemi Tānga me ngā Rauemi Whakapā Kai
He haumaru te CMC, kāore hoki he paitini, ā, ka taea te whakamahi i roto i ngā pūnaha waituhi tā mōkihi kai hei whakapai ake i te piri me te ātete ki te hinu, me te whakatutuki i ngā whakaritenga taiao pēnei i te pirau koiora me te iti o te hekenga.
- Ngā Auahatanga Whakamahinga Auaha o te CMC i roto i te Ahumahi Tā
3.1. Te Whakawhanaketanga o te Whakakapinga Teitei me te CMC Mahi-ā-ringa
Mā te whakanui ake i te taumata o te whakakapinga (DS) me te ōritetanga, ka taea te whakapai ake i te ātete ki te tote, te māramatanga, me te whai huatanga o te matotoru, kia pai ake ai mō ngā waituhi wai-totoka teitei me ngā waituhi inkjet.
3.2. Hangarau Whakaranu Tae Nano-tauine
Te whakaranuCMCKa taea e ngā nano-pigments te whakapai ake i te pumau o te horapa, te whakaiti i te rahi o te matūriki waituhi, me te whakarei ake i te māramatanga tae me te taipitopito i roto i te tānga taumira teitei.
3.3. Tāpiri Matua mō ngā Pūnaha Wai-Paipai, Ā-Taiao hoki
I te mea kei te kaha haere ngā here VOC, kei te tere piki haere te hiahia mō ngā waituhi wai me ngā wanihi wai. He rauemi tūturu tēnei, ā, ka taea te whakahou me te pirau i te CMC, ā, ka noho hei wāhanga nui o ngā hanganga waituhi matomato.
3.4. Te Whanuitanga o te CMC i roto i te Tānga Mamati
Mā te whakarerekē i te taumaha ngota me te tohu matotoru, ka taea te whakarite i te CMC mō te tānga waituhi tere-teitei, ka whakapai ake i te tika o te whakahaere pata me te whakarato i te pumau me te roa ake mō te tānga mamati.
