Te pūhui hauwaioraitiri (HEC)He pūhui kore-ionic, wairewa-wai tēnei i ahu mai i te cellulose taiao kua whakarerekētia e te matū. He tino pai ōna āhuatanga whakamātotoru, hanga kiriata, whakaemulsifying, whakaū, me te pupuri wai. I roto i ngā pūnaha paninga wai, ko te HEC tētahi o ngā whakamātotoru me ngā whakarerekē rheology e whakamahia whānuitia ana. Ko tōna mahi ngātahi ka pā tika ki te kaha mahi o te paninga, te pumau rokiroki, me ngā āhuatanga hanga kiriata.
1. Ngā Mahi Matua a te HEC i roto i ngā Paninga Wai
1.1. Te Whakamatotoru me te Whakarerekētanga Rheology
He tino pai te wairewatanga o te HEC ki te wai me ōna āhuatanga whakamātotoru. Ka whakanui ake i te matotoru o te pūnaha mā te hononga ā-tinana me te here hauwai, ka whakapai ake i ngā āhuatanga rheological o te paninga. Ka hua ake tēnei i te matotorutanga teitei ake i te wā okioki, ka ārai i te taunga o te tae. I te wā e whakamahia ana, ka whakaatuhia e ia ngā āhuatanga angiangi-kutikuti pai rawa atu, ka whakarite i te taurite o te mahi paninga paraihe/roera. He mea nui tēnei āhuatanga rheological "pseudoplastic" mō te paninga maeneene me te hanganga kiriata ōrite.
1.2. Te Whakapūmau i ngā Pūnaha Marara
Ka taea e ngā rōpū hydroxyethyl nui i runga i te mekameka ngota HEC te hanga hononga hauwai, ngā taunekeneke hiko rānei ki ngā mata o ngā tae me ngā whakakī i roto i ngā peita wai-wai, ā, ka whakarei ake i te pumau o te marara. Ka ārai tēnei i te rere o te tae me te whakatō, ka whakapai ake i te pumau o te penapena o te peita, ā, ka roa ake te ora o te hua.
1.3. Te Whakapai Ake i te Mahi o te Taupānga
Mā te tāpiri i te nui o te HEC e tika ana ka whakarei ake i te thixotropy o te peita, ka whakaiti i te tauhiuhi me te totohu i te wā e pania ana. Ina koa i ngā paninga o te mata o te whare, o te tuanui rānei, ka ārai pai te pānga matotoru o te HEC i te totohu, ā, ka whakarite kia ōrite te matotoru o te kiriata. Ka whakapai ake hoki i te hinu i te wā e pania ana ki te paraihe me te roera, ka hua ake he ahua maeneene ake.
1.4. Te Hanganga Kiriata me te Pupuri Wai
Mā te pupuri wai nui o te HEC ka āwhina i te whakahaere i te tere maroke o te paninga, ka ārai i ngā hapa pēnei i te ngatata me ngā kōhao iti i puta mai i te mimiti tere. I roto i ētahi pūnaha, ka āwhina hoki i te hanga i tētahi hanganga kiriata ōrite me te matotoru, ka whakapai ake i te piri me te kanapa o te mata.
1.5. Te Hototahi Kaha me te Urutau Taiao
He whakamātotoru kore-ionic te HEC, he tino hototahi ki ngā momo whakamomona anionic, cationic, me te kore-ionic. Ka taea te whakamahi whānui i roto i ngā pūnaha maha, tae atu ki ngā whakamomona kiriaku, ngā whakamomona vinyl acetate-kiriaku, me ngā whakamomona copolymer ethylene-vinyl acetate, e urutau ana ki ngā taiao tono me ngā whakaritenga whakatakotoranga rerekē.
2. Ngā Whakamahinga o te HEC i roto i ngā Paninga Wai-Kāore
2.1. Ngā Peita Ratex o Roto, o Waho hoki
He mea whakamātotoru te HEC i roto i ngā peita rapa, e whakapai ake ana i te pumau o te peita me te mahi tono. Mō ngā peita o roto, ka whakarei ake i te maeneene o te kiriata me te ātete ki te tauhiuhi; mō ngā peita o waho, ka āwhina ki te whakapai ake i te ātete ki te huarere me te ātete ki te mirimiri.
2.2. Ngā Paninga Rakau Wai-Tuhinga
I roto i ngā pūnaha paninga rakau, ka whakaratohia e te HEC te whakataurite me te māramatanga tino pai, ka whakahaere i te whakahekenga, ā, ka whakarite kia maeneene, kia ōrite te kiriata. Hei tāpiri, ko ōna kakara iti me ōna āhuatanga pai ki te taiao e hangai ana ki te ia whanaketanga o ngā paninga matomato hou.
2.3. Ngā Paninga Wai Ahumahi
Ka taea te whakamahi i te HEC i roto i ngā pūnaha ahumahi pērā i ngā peita ārai-waikura wai, ngā peita papa, me ngā paninga tiaki whakarewa, hei whakapai ake i te pumau o te rokiroki me te urutau ki te tono, e tuku ana i ngā painga o te whakahaere utu me te mahi pumau.
2.4. Ngā Paninga Toi me ngā Paninga Pānga Motuhake
Nā te mea ka taea te whakahaere i te rheology me te hototahi pai o te pūnaha, ka taea te whakamahi i te HEC ki ngā paninga pānga motuhake pērā i ngā peita kakano onepu, ngā peita rite ki te kōhatu, me ngā peita kakano, hei āwhina i te whakatutuki i ngā kakano whakapaipai me ngā kakano mata motuhake.
3. Ngā Āhuatanga Whakamahinga o te HEC i roto i ngā Paninga Wai
I te mea he kaha ake ngā ture taiao me te whakakorenga āta haere o ngā paninga whakarewa, kei te piki haere tonu te wāhi mākete o ngā paninga wai. Hei whakamātotoru i ahu mai i te taiao, he iti te paitini, he pai hoki mō te taiao, e hangai ana a HEC ki te ia o te umanga ki ngā hangarau matomato, iti te VOC. Ko ngā ahunga whanaketanga ā muri ake nei mō HEC ka arotahi ki ngā wāhanga e whai ake nei:
Whakarerekētanga Mahi-Teitei: Te whakapai ake i te ātete kutikuti, te ātete whākōkī, me te pumau pāmahana mā te whakarerekētanga hanganga hei whakatutuki i ngā hiahia o ngā pūnaha paninga teitei.
Mana Rheology Atamai: Mā te whakawhanake i ngā pānga HEC me ngā āhuatanga aro-kutikuti me te aro-pāmahana ka taea te whakarerekē tika ake i te mahi tono.
Ngā Mahi Whakaranu: Mā te whakaranu ki te polyurethane, ki ngā whakarerekētanga rheology kiriaku, ki ngā etera cellulose rānei ka hangaia he pūnaha whakamātotoru hiato, ka whakarei ake i te mahi whānui me te whai huatanga utu.
HECehara i te mea he whakamātotoru tuku iho i roto i ngā paninga wai anake, engari he tāpiri mahi matua hoki e tutuki ai te taurite i waenga i te kaha mahi me te mahi taiao. I te whanaketanga hangarau me te tipu haere o te hiahia mō ngā rauemi hanga matomato, e matapaetia ana ka whānui ake ngā tūmanakohanga tono mākete.
