Te pūhui hauwaioraitiri (HEC)He pūhui pūmua kore-ionic, wairewa-wai te HEC, i whiwhihia mā te whakarerekētanga matū o te cellulose tūturu. Nā te mea he pai rawa atu ōna āhuatanga whakamātotoru, whakaemulsifying, whakatārewatanga, whakaū, me te hototahitanga, e whakamahia whānuitia ana te HEC i roto i te umanga matū o ia rā, inā koa i roto i ngā hua horoi wai pērā i ngā wai horoi rihi, ngā hopi ringa, me ngā shampoo.
1. Te Tūranga Mahi a te HEC i roto i ngā Wai Horoi Rīhi
I roto i ngā wai horoi rihi, ko ngā mahi matua a HEC ko ēnei e whai ake nei:
Te Whakamātotoru me te Whakahaere: Ka whakanuia e te HEC te matotoru o te pūnaha wai horoi rihi, ka pai te āhua, te rere o te wai, me te wheako kaiwhakamahi.
Te Whakapūmau i te Whakatārewatanga: I roto i ngā wai horoi rihi kei roto ngā tāpiringa matūriki (pēnei i ngā matūriki tango kiri me te paura pērara), ka taea e te HEC te aukati i te whakatōnga matūriki me te pupuri i te ōritetanga o te hanganga.
Te Whakapūmau i te Pahuka: Ka taea e te HEC te mahi tahi me ngā matū horoi hei whakapai ake i te pai me te pumau o te pahuka.
Whakatikatika Hototahi: Hei pūmua kore-ionic, he tino hototahi te HEC ki ngā matū horoi anionic, cationic, me te kore-ionic, ā, ka ārai i te wehewehenga o ngā hanganga.
2. Tikanga Pūmautanga HEC
2.1. Te Pūmautanga o te Wera
He pai ake te pumau o te HEC i te pāmahana i te nuinga o ngā pūmua taiao. I roto i ngā pūnaha matū o ia rā i te 25–50°C, ka mau tonu te hanganga ngota o te HEC, ā, kāore e ngawari te pirau.
Ahakoa i roto i ngā taiao whakaputa pāmahana teitei (pērā i te wā rewa me te whakamahana) me ngā taiao rokiroki mō te wā roa, ka mau tonu te matotoru pai o ngā pūnaha HEC-matotoru me te kore e tino angiangi. He mea nui tēnei āhuatanga mō te hoko pumau o ngā hopi horoi i te wā e kawe ana i te pāmahana teitei, i ngā mākete tonga rānei.
2.2. Te Pūmautanga o te Ionic
He maha ngā wā kei roto i ngā wai horoi rihi ngā tote kore-waro (pērā i te konutai pūhaumāota me te konutai whanariki) me ngā wāhanga irahiko. He maha ngā wā ka ngoikore te pānga o ngā whakamātotoru noa i ēnei katote. Heoi, hei pūmua kore-ionic, kāore e pāngia te mahi whakamātotoru HEC e ngā huringa o te kukū irahiko.
I roto i ngā pūnaha tote nui, ka mau tonu te matotoru me te mārama o te HEC, ka ārai i te maturuturunga me te wehewehenga o te tote i roto i ngā hopi horoi i te wā e rongoa ana.
2.3. Te pumau o te pH
Ko te pH o ngā wai horoi rihi kei waenganui i te 6.5 me te 8.5. He tino pai te pumau matū o te HEC i roto i tēnei awhe, me te kore e pakaru, e kore rānei e whakahohe. Ahakoa kei roto i te hanganga he matū paku kawakore, he matū waikawa rānei, ka mau tonu te makuku kaha o ngā mekameka ngota HEC, kia mau tonu ai te ōritetanga o te pūnaha.
Hei tāpiri atu, ko te āhua kore-ionic o te HEC ka karo i te pokanoa o te utu e puta mai ana i ngā piki me ngā heke o te pH, kia noho mārama tonu ai te wai horoi rihi mō te wā roa.
2.4. Te Pūmautanga o te Hototahi
He tino pai te hototahitanga o te HEC ki ngā momo surfactants (pēnei i te AES, LAS, APG, me ētahi atu) me te kore e puta he flocculation, he stratification rānei. Ka taea e ōna mekameka ngota te hanga taunekeneke ngoikore ki ngā surfactants i roto i te otinga, ā, ka whakapai ake i te viscoelasticity me te pumau o te pahuka o te pūnaha.
I roto i ngā pūnaha matatini kei roto ngā kakara matū, ngā tae, me ngā mea tiaki, ka mau tonu te marara pai o te HEC, ka ārai i te wehenga o ngā wāhanga, i te ua rānei i te wā e rokiroki ana mō te wā roa.
3. Ngā Take Matua e Pā Ana ki te Pūmautanga o te HEC
3.1. Te Tohu Whakakapinga (DS) me te Tohu Matotoru:
He pai ake te wairewa me te manawanui tote o ngā HEC whakakapinga-teitei, ā, he pai mō ngā hanganga hopi mārama; he kaha ake te kaha whakamātotoru o ngā hua whakakapinga-iti engari he iti ake te pumau. I te nuinga o te wā, ka whiriwhiria ngā HEC he matotoru waenga ki te teitei (25000–60000 mPa·s) hei taurite pai ake i te whakamātotoru me te mārama.
3.2. Tukanga Whakakorenga:
Me horahia te HEC kia ōrite ki te wai matao, kātahi ka whakamahana mārire kia memeha rawa, kia kore ai e piri. Mēnā kāore i tino memeha, ka ngāwari te puta o ngā matūriki, te pōuri rānei i roto i te pūnaha, ā, ka pā ki te pumau o te hanganga.
3.3. Te Hanganga o te Kukū o te Irahiko:
Ahakoa he pai te manawanui o te HEC ki te tote, tera pea ka heke te matotoru ina nui rawa te kukū o te electrolyte i roto i te pūnaha (>6% NaCl). Nō reira, i roto i ngā hanganga tote-nui, me whakanui ake te nui o te HEC i tāpirihia, me whiriwhiri rānei i tētahi momo HEC kua whakarerekētia.
3.4. Momo Kaihoroi:
He paku rerekē te hototahitanga o te HEC ki ngā pūnaha surfactant rerekē. Hei tauira, he pai ake te pumau o te pahuka a te HEC i roto i ngā pūnaha LAS me te AES; i roto i ngā wai horoi rihi e pai ana ki te taiao kei roto ko te APG, he nui ake te kitea o ngā pānga whakamātotoru me te whakatārewatanga o te HEC.
4. Ngā Painga o te HEC i roto i ngā Wai Horoi Rīhi
Te Māramatanga o te Pūnaha: He mārama, he mārama hoki te wai kua rewa, ā, kāore e pā ki te āhua o te wai horoi rihi.
Pai te pirau: I ahu mai i te cellulose tūturu, e hangai ana ki te ia o ngā hua matū o ia rā e pai ana ki te taiao.
He iti te riri: Kāore e pāngia te kiri e te mate pāwera, ā, he pai mō ngā wai horoi rihi ngawari.
Hototahi Whānui: E pā ana ki ngā momo pūnaha wai horoi rihi rerekē, pērā i ngā wai horoi rihi kūpapa, ngā tātai kukū, me ngā tātai huka nui, huka iti rānei.
HECEhara i te mea he whakamātotoru pai noa iho i roto i ngā wai horoi rihi engari he mea whakaū pūnaha matua hoki. Nā tōna pumau wera, pumau ionic, pumau pH, me te hototahitanga pai rawa atu ka mau tonu te āhua me te mahi pai o ngā wai horoi rihi i te wā e rongoa ana, e kawe ana, e whakamahia ana hoki. Mā te whiriwhiri tika i ngā momo HEC me ngā tukanga tāpiri, ka taea te whakapai ake i te kounga whānui me te whakataetae mākete o ngā wai horoi rihi. I te heke mai, me te whanaketanga o te tiaki taiao matomato me te matū pumau, ka whakaatu a HEC i ngā tūmanako whānui mō te tono i roto i ngā hua hopi kounga teitei.
