Te pūhui hauwaioraitiri (HEC)He pūmua wairewa-kore-ionic te HEC. He whānuitia te whakamahinga i roto i te umanga paninga nā te mea he pai te wairewatanga ki te wai, he matotoru, he āhuatanga hanga kiriata, he pai hoki te mahi mata. I roto i ngā hanganga paninga, ehara i te mea ka whakaratohia e te HEC ngā āhuatanga rheological e tika ana, engari he mahi nui anō hoki ki te piri o ngā paninga.
1. Ngā āhuatanga hanganga o te HEC
He mea tito ngā ngota HEC i ngā mekameka cellulose me ngā whakakapinga hydroxyethyl. He hanganga polyhydroxy tō tōna mekameka cellulose, ka taea te hanga i tētahi taunekeneke kaha ki te mata o te papa paninga mā roto i ngā hononga hauwai, ā, ka pai ake te piri o te paninga. Hei tāpiri, ka whakanuia e te whakakapinga hydroxyethyl i roto i te ngota AnxinCel®HEC tōna wairewatanga wai, ka taea ai te horapa ōrite i roto i te paninga, ā, ka pai ake te kounga hanga kiriata o te paninga.
2. Te Tikanga o te HEC ki te Piringa Paninga
Ko te HEC i roto i ngā paninga ka whakarei ake i te piri o ngā paninga mā roto i ngā tikanga e whai ake nei:
Te whakapai ake i te makuku o te mata
He pai te kaha o te mata o te HEC, ka taea te whakaiti i te kukū o te mata o te paninga, me te whakapai ake i te mākū o te paninga ki te mata o te papa. Mā tēnei mākū ka taea e te paninga te pā tata atu ki te mata o te papa, ka whakaiti i ngā āputa i te atanga, ā, ka whakapai ake i te piri i waenga i te paninga me te papa.
Ka whakarei ake te hononga hauwai i te hononga ā-kanohi
Ka taea e ngā rōpū hydroxyl i roto i ngā ngota HEC te hanga hononga hauwai me ngā rōpū mahi porowhita i runga i te mata o te papa (pērā i te rakau, te karāhe, te konganuku, me ētahi atu). Ka whakarei ake tēnei pānga i te hononga ā-tinana i waenga i te paninga me te papa, ka iti ake te tūponotanga o te paninga ki te tihore i raro i ngā kaha o waho.
Te whakahaere i ngā rawa rheological
He pānga nui tō te HEC ki te whakahaere i ngā āhuatanga rheological o te paninga, ka whakaiti i tōna rere mā te whakamātotoru i te paninga me te ārai i te totohu nui o te paninga i runga i te mata o te papa. Ka āwhina tēnei āhuatanga i te paninga ki te hanga i tētahi kiriata ōrite ki runga i te mata o te papa, me te whakaiti i te hekenga o te piri i puta mai i te matotoru o te kiriata kāore i te ōrite.
Te pānga āwhina hanga kiriata
Ka taea e te HEC te whakapai ake i te kounga hanga kiriata o te paninga i te wā e hanga kiriata ana, kia mau tonu ai te paninga, kia ōrite ai hoki i muri i te maroke. Mā tēnei ōritetanga ka whakaitihia ngā wāhi hapa o te paninga, ā, ka whakapai ake i te piri whānui.
3. Ngā tauira o ngā tono HEC i roto i ngā paninga rerekē
Ngā paninga hoahoanga wai
I roto i ngā paninga hoahoanga, ka whakapai ake a HEC i te piri o ngā paninga ki ngā papa pakitara (pērā i te sima, te gypsum rānei) mā te whakamātotoru, te whakapai ake i te mākū, me te whakapakari i te kaha o te kiriata. Hei tāpiri, ka whai wāhi ngā āhuatanga ārai-totoka o HEC ki te maeneene o te mata o te paninga i muri i te paninga.
Ngā paninga rakau
Mō ngā paninga rakau, he tino kitea te pānga here hauwai o te HEC. He nui ngā rōpū hydroxyl i te mata o te rakau, ā, ka taea e te HEC te hanga hononga piri ki a ia, ka whakapai ake i te roa me te piri o te paninga.
Ngā paninga whakarewa
I roto i ngā paninga whakarewa, mā te whakapai ake i te mākū o te HEC ka taea e te paninga te kapi pai ake i te mata whakarewa, ā, ka whakarei ake i te piri o te paninga mā te polarity. He mea nui tēnei i roto i ngā paninga ārai-waikura.
Ngā paninga karāhe
He pai te pānga piri o te HEC ki ngā mata maeneene kore-pororaru pērā i te karāhe, ā, mā ngā āhuatanga pororaru o ngā rōpū hydroxyl i roto i ōna ngota ka taea te whakakī i te korenga o te hototahi matū i waenga i te mata karāhe me te paninga.
4. Ngā herenga o te HEC ki te piri o te paninga
AhakoaHECHe nui ngā painga o te HEC ki te whakapai ake i te piri o te paninga, engari he iti anō hoki ōna herenga. Hei tauira, he ngāwari te mimiti i te makuku i roto i te taiao haumākū nui, ā, ka heke pea te mahi paninga. Hei tāpiri, mō ētahi paninga ahumahi e hiahiatia ana, me whakamahi tahi te HEC me ētahi atu tāpiringa hei whakatutuki i te mahi teitei ake.
Hei mea whakamātotoru me te tāpiri hanga kiriata nui, mā te whakamahinga o te AnxinCel®HEC ki ngā paninga ka tino whakapai ake i te piri o ngā paninga. Mā tēnei ka taea e ngā paninga te urutau pai ake ki ngā momo papa mā roto i ngā tikanga maha pēnei i te whakarei ake i te mākū, te hanga hononga hauwai, me te whakapai ake i ngā āhuatanga hanga kiriata. Heoi, i roto i ngā whakamahinga tūturu, me arotau te nui o te tāpiri me te hototahi o te HEC me te tauira paninga motuhake me te taiao whakamahi kia tino whai hua ai tana mahi.
