Te Pūtauora Waikawa (HEC)He pūmua wai-wairewa kore-ionic tēnei e whakamahia whānuitia ana i roto i ngā paninga wai hei whakamātotoru, hei whakaū, hei āwhina hanga kiriata, hei kaiwhakatārewa hoki. He pai tana mahi i roto i ngā paninga wai, nō reira he tūranga nui tōna i roto i ngā mara o ngā paninga whare, ngā peita rapa, ngā paninga ahumahi me ngā paninga toi.
1. He pai te mahi whakamātotoru
Ko tētahi o ngā painga nui o te hydroxyethyl cellulose ko tōna mahi whakamātotoru pai rawa atu. I roto i ngā paninga wai-wai, he mea nui te matotoru tika mō te mahi a te paninga, te āhuatanga hanga kiriata me te pumau o te rokiroki. Ka taea e te HEC te whai wāhi whakamātotoru pumau i raro i ngā āhuatanga pH rerekē, ā, he tino pai mō ngā pūnaha maha-wāhanga pērā i ngā peita rapa. Ka taea e ia te whakahaere pai i te whanonga rheological o te paninga, te ārai i te totohu, me te whakapai ake i te ahua o te paraihe, te paninga roera me te paninga papatahi i te wā hanga.
He tairongo te HEC ki te tere kutikuti, ā, he āhuatanga rūpahu-pēnei tōna, arā, he nui ake te matotoru i raro i ngā āhuatanga kutikuti iti, ā, ka heke te matotoru i raro i ngā āhuatanga kutikuti teitei i te wā hanga, he mea e āwhina ana ki te horapa me te whakataurite i te paninga.
2. He pai te mahi marara me te pumau
Kei roto i ngā peita wai ngā wāhanga pēnei i ngā tae, ngā whakakī, ngā whakaehu me ngā momo tāpiri. He tino uaua te pūnaha, ā, he ngāwari ki te whakatō me te whakarōpū. Hei pūmua kore-ionic, ka taea e te HEC te takai i ngā matūriki tae me ngā whakakī mā te hanga i tētahi hanganga whatunga toru-ahu, ka whakapai ake i te marara me te pumau o te pūnaha, ka ārai i te whakatō matūriki, ā, ka roa ake te wā rokiroki o te peita.
Nā te āhua kore-ionic o te HEC e hototahi ana ki ngā emulsions cationic, anionic me te kore-ionic, ngā tāpiringa rānei, ā, e kore e puta he tauhohenga kino ki ētahi atu kai, kia mau ai te pumau o te tauira peita.
3. Whakapai ake i te mahi hanga o te peita
Ka pā tika te mahi hanga ki te pānga o te paninga o te peita. Ka taea e te HEC te whakapai ake i te maeneene o te paraihe, te hurihuri me te paninga papatahi i roto i ngā peita wai-wai, te whakaiti i te tauhiuhi, me te whakangawari me te whai hua ake o te tukanga hanga. Mā tōna āhua rūpahu pai ka ārai i te peita kei totohu ina pania ki ngā mata poutū, kia rite ai, kia papatahi ai te paninga.
Ka taea e te HEC te whakarato i ngā āhuatanga hanga kiriata pai i te wā whakamaroke, kia maeneene ai te paninga, kia kore ai e pāngia e ngā hapa pēnei i te kōhao iti, te mimiti, me te ngatata, kia pai ake ai te pānga whakapaipai o te paninga.
4. Hoatu he pai te pupuri wai me ngā āhuatanga hanga kiriata ki te paninga
I te wā e whakamaroke ana te peita, he mea nui te mimiti o te wai kia pai ai te kounga o te hanganga kiriata. He pai te mahi pupuri wai a te HEC, ka taea te whakaroa i te tere mimiti o te wai, ka taea te whakarite me te whakaoti i te tukanga hanganga kiriata, ā, ka whakaiti i ngā raruraru o te paura me te pakaru i puta mai i te maroke tere rawa. Ina koa ka whakamahia i raro i te pāmahana teitei, i te taiao maroke rānei, ka tino whakapai ake te HEC i te matapihi mahi hanga me te whakapai ake i te kounga o te paninga.
5. Te tiaki taiao, te haumaru me te hototahi pai
I ahu mai te HEC i te cellulose tūturu, ā, he mea hanga mā te whakarerekētanga matū ngawari. Kāore he whakarewa kino me ngā matū waro pūngāwerewere (VOC) i roto, e hangai ana ki te ahunga whanaketanga o ngā paninga hou "matomato, tiaki taiao, me te waro iti". He haumaru, kāore hoki he paitini i te wā e whakamahia ana, kāore he pānga kino ki te tinana tangata me te taiao, ā, ko tētahi o ngā whakamātotoru taiao e whakamahia whānuitia ana i roto i ngā paninga wai.
Nā te mea he kore-ionic te HEC, he pai mō ngā pūnaha whakaehu ionic maha, he pai te hototahi ki ngā tāpiringa e whakamahia whānuitia ana, ā, ka taea te whakamahi whānuitia i roto i ngā paninga wai-wai me ngā whakaritenga mahi rerekē, pērā i ngā paninga pakitara o roto, ngā paninga pakitara o waho, ngā paninga ātete-mirimiri, ngā paninga ātete-haruru me ngā paninga huakita, me ētahi atu.
6. He pai te pumau o te rokiroki
He pai te pumau o te wai HEC i roto i te rokiroki mō te wā roa, ā, kāore e ngāwari te pirau e ngā moroiti. Kua tāpirihia ētahi hua HEC ki ngā aukati harore i mua i te tukanga whakaputa, e whakarei ake ana i ngā āhuatanga patu huakita me te ārai waikura, e whakaroa ana i te roa o te oranga o ngā hua paninga, ā, e whakaiti ana i te mōrearea o te pirau i puta mai i te rokiroki hē.
7. Ngā momo kanorau me te urutau tono
I tēnei wā, he maha ngā hua HEC me ngā nekehanga whakakapinga me ngā taumata matotoru rerekē kei te mākete, ka taea te whiriwhiri i runga i te momo paninga me te tikanga hanga motuhake (pēnei i te rehu, te hurihuri, te paraihe). He pai te HEC matotoru-teitei mō ngā wāhi e hiahia ana ki te paninga matotoru, ko te HEC matotoru-iti ia he pai mō ngā hua paninga he nui ngā whakaritenga mō te hanga ngāwari, e whakarei ake ana i te maha o ngā mahi me te whakataetae mākete o te hua.
Hei tāpiritanga tino nui, he mea nui hoki i roto i ngā paninga wai,He mea nui te mahi a te hydroxyethyl cellulose i roto i te umanga paninga hou nā te mea he tino matotoru., te whakau, te hanga, te hanga kiriata me ngā āhuatanga tiaki taiao. I te mea kei te kaha haere ngā ture taiao me te whanaketanga tonu o te hangarau paninga wai, ka whānui ake ngā tūmanakohanga whakamahinga o te HEC, ā, ka noho ko tōna arotautanga mahi me te whakawhānui i te tono hei huarahi nui mō ngā rangahau ā muri ake nei.
