I roto i te umanga peita, he mea nui te pumau me te rheology o te whakapiri tae. Heoi, i te wā e rongoa ana, e whakamahia ana hoki, he maha ngā raruraru o te whakapiri tae pēnei i te matotoru me te whakakotahi, ka pā ki te pānga hanga me te kounga paninga.Te pūhui hauwaioraitiri (HEC), hei whakamātotoru pūmua wairewa-wai noa, he mea nui tana mahi i roto i ngā hanganga peita. Ka taea e ia te whakapai ake i ngā āhuatanga rheological o te whakapiri tae, te ārai i te kohikohi, me te whakapai ake i te pumau rokiroki.
1. Ngā take mō te matotoru me te whakakotahitanga o te whakapiri tae peita
Ko te matotoru me te whakaemi o te whakapiri tae peita e pā ana ki ngā āhuatanga e whai ake nei:
Te mararatanga o te tae kore pumau: Ka taupatupatu pea ngā matūriki tae i roto i te whakapiri tae i te wā e rongoa ana, ka hua ake he nui rawa te kukū me te haaputuputu.
Te mimiti o te wai i roto i te pūnaha: I te wā e rongoa ana, ka piki ake te matotoru o te whakapiri tae i te mimiti o tētahi wāhanga o te wai, ā, ka puta he mea maroke ki runga i te mata.
Te kore hototahi i waenga i ngā tāpiringa: Ka tauhohe pea ētahi matū whakamātotoru, kaiwhakamarara, ētahi atu tāpiringa rānei tetahi ki tetahi, ka pā ki ngā āhuatanga rheological o te whakapiri tae, ka hua ake he pikinga matotoru rerekē, he hanganga flocculent rānei.
Te pānga o te kaha kutikuti: Mā te whakaoho, te papu rānei ā-ringa mō te wā roa ka pakaru te hanganga mekameka pūmua i roto i te pūnaha, ka whakaiti i te rere o te whakapiri tae, ka nui ake te matotoru, te matotoru rānei.
2. Te tikanga mahi a te hydroxyethyl cellulose
Ko te Hydroxyethyl cellulose (HEC) he matū kore-ionic cellulose, he pai te matotoru, te kaha ki te whakarite i te rheological me te pumau o te horapa. Ko tōna tikanga mahi matua i roto i te whakapiri tae peita ko:
Te whakamātotoru me te whakatikatika rheological: Ka taea e te HEC te whakakotahi me ngā ngota wai mā te hononga hauwai hei hanga i tētahi paparanga waikura pumau, hei whakanui ake i te matotoru o te pūnaha, hei ārai i te kohikohi me te taunga o ngā matūriki tae, me te whakarite kia mau tonu te rere pai o te whakapiri tae i te wā e tū ana, e hangaia ana rānei.
Pūnaha marara pumau: He pai te mahi mata o te HEC, ka taea te pani i ngā matūriki tae, te whakarei ake i tō rātou marara i roto i te wāhanga wai, te ārai i te kohikohinga i waenga i ngā matūriki, ā, nā reira ka whakaitihia te flocculation me te agglomeration.
Ārai i te mimiti wai: Ka taea e te HEC te hanga i tētahi paparanga tiaki, te whakaroa i te tere mimiti o te wai, te ārai i te matotoru o te whakapiri tae nā te ngaronga o te wai, me te whakaroa i te wā rokiroki.
Ātete kutikuti: Ka hoatu e te HEC he thixotropy pai ki te peita, ka whakaiti i te matotoru i raro i te kaha kutikuti teitei, ka whakahaere i te hanganga, ā, ka taea te whakahoki wawe i te matotoru i raro i te kaha kutikuti iti, ka whakapai ake i te mahi ārai-totoka o te peita.
3. Ngā painga o te hydroxyethyl cellulose i roto i te whakapiri tae peita
Ko ngā painga o te tāpiri i te hydroxyethyl cellulose ki te pūnaha whakapiri tae peita e whai ake nei:
Te whakapai ake i te pumau o te rokiroki o te whakapiri tae: Ka taea e te HEC te aukati i te whakatō me te kohikohinga o te tae, kia mau tonu ai te rere o te whakapiri tae i muri i te rokiroki roa.
Te whakapai ake i te mahi hanga: Ka hoatu e te HEC ki te whakapiri tae he āhuatanga rheological tino pai, kia māmā ai te paraihe, te hurihuri, te rehu rānei i te wā hanga, ka whakapai ake i te urutau hanga o te peita.
Te whakapakari i te ātete wai: Ka taea e te HEC te whakaiti i te huringa matotoru i puta mai i te mimiti wai, kia mau tonu ai te pumau o te whakapiri tae i raro i ngā āhuatanga taiao rerekē.
Hototahi kaha: He whakamātotoru kore-ionic te HEC, he pai te hototahitanga ki te nuinga o ngā mea whakamarara, ngā kaihoko whakamakuku me ētahi atu tāpiringa, ā, e kore e puta he kore pumau i roto i te pūnaha whakatakotoranga.
Te tiaki taiao me te haumaru: Ko te HEC i ahu mai i te cellulose taiao, e tutuki ana i ngā whakaritenga tiaki taiao, kāore e tuku i ngā matū kino, ā, e hangai ana ki te whanaketanga matomato me te tiaki taiao o ngā paninga wai.
4. Te whakamahinga me ngā whakaaro mō te hydroxyethyl cellulose
Hei whakapai ake i te mahi a te HEC, me mārama ēnei āhuatanga ina whakamahia ana i roto i te tātai whakapiri tae paninga:
Te whakahaere tika i te nui o te tāpiri: Ko te nui o te HEC kei waenga i te 0.2%-1.0%. Me whakarerekē te nui o te whakamahinga kia rite ki ngā hiahia o te pūnaha paninga kia kore ai e nui rawa te matotoru, ā, kia pā ki te mahi hanga.
Te tukanga i mua i te whakarewanga: Me whakamarara te HEC, ka whakarewahia ki te wai i te tuatahi, kātahi ka tāpirihia ki te pūnaha whakapiri tae i muri i te hanga i tētahi otinga ōrite kia tino whai hua ai ōna pānga whakamātotoru me te marara.
Whakamahia me ētahi atu tāpiringa: Ka taea te whakataurite ki ngā mea whakamarara, ngā kaihoko whakamakuku, me ētahi atu hei whakapai ake i te pumau o te marara o ngā tae me te arotau i te mahi paninga.
Āraia ngā pānga pāmahana teitei: He nui te pānga o te pāmahana ki te wairewatanga o te HEC. E taunakihia ana kia wairewahia ki te pāmahana e tika ana (25-50℃) hei karo i te kohikohi, i te kore rānei e ranea te wairewatanga.
Te pūhui hauwaioraitiriHe mea nui te whakamahinga o te whakapiri tae peita. Ka taea e ia te whakaoti rapanga o te matotoru me te whakakotahitanga o te whakapiri tae, me te whakapai ake i te pumau o te rokiroki me te mahi hanga. Nā te matotoru, te pumau o te horapa me te ātete ki te mimiti wai, he mea nui tēnei hei tāpiri mō ngā peita wai. I roto i ngā whakamahinga mahi, mā te whakarerekētanga tika o te horopeta HEC me te tikanga tāpiri ka taea te whakanui ake i ōna painga me te whakapai ake i te kounga whānui o te peita. Mā te whanaketanga o ngā peita wai-hoahoa taiao, ka whānui ake ngā tūmanakohanga whakamahinga o te HEC.
