WHAKAITI WAI AWHINA TEITEI (SMF)He mea hanga ki te anion wairewa-wai, he nui te polymer o te anion hiko. He kaha te mimiti o te SMF, ā, he pānga motuhake ki te sima. Ko te SMF tētahi o ngā paipa wai i roto i te raima whakaiti wai. Ko ngā āhuatanga matua: he mā, he tere whakaiti wai teitei, he momo kore-hau, he iti te ihirangi katote hauota, kāore e waikura i runga i ngā pae maitai, ā, he pai te urutau ki ngā momo sima. I muri i te whakamahinga o te raima whakaiti wai, ka nui ake te kaha me te uruhanga o te raima i te tīmatanga, ka pai ake ngā āhuatanga hanga me te pupuri wai, ā, ka whakarerekētia te tiaki mamaoa.
I roto i te hinganga o te raima, ko te āhua ōrite tonu ka taea te whakaiti i te ranunga wai whakaranu e kiia nei ko te kaihoko whakaiti wai tino whai hua. Mēnā ka tupu te hinganga o te raima, ka taea te whakaiti i te nui o te wai e pau ana i te whakaranu me te wai mā te neke atu i te 15%.
Te whanaketanga hītori:I whakawhanakehia te whakatupuranga tuatahi o te kaihopu whakaiti wai tino whai hua me te superplasticizer e hangai ana ki te amine resin i te tīmatanga o te tekau tau atu i 1960. Nā te mahi a te kaihopu whakaiti wai noa e te lignesulfonate i whakawhanakehia i te mutunga o te tekau tau atu i 1930, e mōhiotia ana hoki ko te super plasticizer. Ko te kaihopu whakaiti wai tino whai hua o te whakatupuranga tuarua ko te amino sulfonate, ahakoa i muri i te whakatupuranga tuatoru o te superplasticizer - raupapa waikawa polycarboxylic. Ko te copolymer honohono me te waikawa sulfonic me te waikawa carboxylic te mea tino nui i roto i te whakatupuranga tuatoru o te kaihopu whakaiti wai tino whai hua, ā, ko tana mahi ko te kaihopu whakaiti wai tino mahi pai rawa atu.
Ngā momo matua:Ka taea e te tere whakaheke wai tino whai hua te eke ki te neke atu i te 20%. Ko te nuinga o ēnei he raupapa naphthalene, he raupapa melamine me te kaihoko whakaiti wai, ā, ko te raupapa naphthalene te mea matua, e 67%. Ina koa, ko te nuinga o ngā kaihoko whakaiti wai tino whai hua he mea hanga ki te naphthalene hei rauemi mata matua. E ai ki te ihirangi o te Na2SO4 i roto i te superplasticizer raupapa naphthalene, ka taea te wehewehe ki ngā hua kukū teitei (ihirangi Na2SO4 < 3%), ngā hua kukū waenga (ihirangi Na2SO4 3%-10%) me ngā hua kukū iti (ihirangi Na2SO4 > 10%). Ko te nuinga o ngā tipu hanga superplasticizer naphthalene he kaha ki te whakahaere i te ihirangi o te Na2SO4 i raro i te 3%, ā, ka taea e ētahi umanga matatau te whakahaere i te ihirangi o te NA2SO4 i raro i te 0.4%.
Ko te raupapa naphthalene o te kaihopu whakaiti wai te mea nui rawa atu i roto i tō tātou whenua, ko te kaihopu whakaiti wai tino whai hua (neke atu i te 70% o te nui o te kaihopu whakaiti wai), e tohuhia ana e te tere whakaheke wai teitei (15% ~ 25%), kāore he hau, he iti te pānga ki te wā whakatakoto, he pai te urutau ki te sima, ka taea te whakamahi me ētahi atu momo tāpiringa matū, he iti hoki te utu. He maha ngā wā ka whakamahia te Naphthalene superplasticizer ki te whakarite i te raima he nui te nekenekehanga, he kaha teitei me te mahi teitei. He tere ake te ngaronga o te hinganga o te raima me te naphthalene superplasticizer. Hei tāpiri, me whakapai ake te urutau o te naphthalene raupapa wai me ētahi sima.
Ngā Āhuatanga:He kaha te pānga o te matū whakaiti wai tino whai hua ki te sima, ka taea te whakapai ake i te rere o te ranunga sima me te mimiti o te raima, me te whakaiti i te wai e pau ana, ka whakapai ake i te mahi o te raima. Engari ka tere ake te ngaronga o te mimiti o te raima e ētahi matū whakapūkara nui, ā, ka nui rawa te whakaranu ka rere te wai. Kāore te matū whakaiti wai tino whai hua e whakarerekē i te wā whakatakoto o te raima, ā, he iti noa te pānga whakaroa ina nui te horopeta (nui rawa te whakauru), engari kāore e whakaroa i te tipu kaha wawe o te raima whakapakeke.
Ka taea e ia te whakaiti i te wai e pau ana, ā, ka whakapai ake i te kaha o te raima i ngā tau rerekē. Mēnā ka mau tonu te kaha, ka taea te penapena i te sima mā te 10% neke atu rānei.
He iti te nui o te katote pūhaumāota, kāore he pānga waikura ki te pae maitai. Ka taea e ia te whakarei ake i te ātete ki te waikura, te ātete ki te huka-rewa me te ātete ki te waikura o te raima, me te whakapai ake i te roa o te ora o te raima.
TONO:
1, He pai mō ngā momo hanganga ahumahi me ngā hanganga ā-iwi katoa, te tiaki wai, te kawe waka, te tauranga, te hanganga miihini ā-tāone me te raima whakapakari i makahia ki te wāhi.
2, He pai mō te raima kaha teitei, te kaha tino teitei me te kaha waenga, me ngā whakaritenga o te kaha wawe, te ātete huka ngawari, te raima tere nui.
3, He pai mō ngā mema raima kua oti te hanga o te tukanga whakaora mamaoa.
4, He pai mō ngā momo ranunga matū o ngā wāhanga whakapakari whakaiti-wai (Master Batch).
Tākai: 25kg/Pēke
Rokiroki: Rokiroki ki roto i te pouaka kua kati pai, ātete ki te mārama, me te tiaki mai i te makuku.
