Nō nā tata nei, kua angitu te rōpū R&D o Shanghai Qixuan Chemical Technology Co., Ltd. ki te whakawhanake i tētahi ranunga anionic-nonionictāpiri patu pepeke. He mea hanga ki te hinu kātoro ethoxylate, te butyl EO-PO block polyether me te calcium dodecylbenzenesulfonate hei wāhanga matua, e aro ana tēnei hua ki ngā āhuatanga uaua o te ahumahi i roto i te whanaketanga o ngā patupatu, tae atu ki te ngoikore o te pumau o te emulsion, te rerenga o te pata rehu, te huka me te ngoikore o te ātete ki te wai mārō. He mea hanga mō ngā hanganga patupatu rongonui pērā i ngā kukū emulsiable, ngā emulsion hinu-i-roto-i-te-wai me ngā microemulsions. Ka taea e tēnei tāpiringa whakaranu hou te āwhina i ngā kaihanga ki te whakaoti i ngā wero hanganga me te waihanga uara hou i waenganui i te akiaki mō te whakaiti i ngā patupatu me te whakapai ake i te whai huatanga?
Kei te tino rerekē te hanganga o te umanga patu pepeke. I te whakatinanatanga tonu o ngā kaupapa here ā-motu mō te whakaiti i ngā patu pepeke, te whakarei ake i te whai huatanga me te whakakapinga i ngā hanganga matomato, kei te aro atu ngā kaihanga ki te pikinga o te pēhanga R&D. I tētahi taha, kei te akiaki te mākete i te whanaketanga o ngā hanganga kawenga-nui, me te whakawhāiti i te whakamahinga o te whakarewa waro, me te whakatakoto i ngā whakaritenga pakari ake mō te kaha whakapūkara me te hototahitanga pūnaha o ngā tāpiringa. I tētahi atu taha, he tino rerekē ngā āhuatanga tono mara, me te rerekētanga whānui o te pakeketanga o te wai puta noa i ngā rohe me te matotoru koretake o ngā kiriuhi ware pi i runga i ngā rau hua. He maha ngā hanganga e paahitia ana ngā whakamātautau taiwhanga engari e pāngia ana e te rere o ngā pata, te kore e ranea te whakatakotoranga o ngā matū hohe me te kore e pai te whai huatanga mara ina waimeha me te rehu i raro i ngā āhuatanga mara.
He maha ngā wā ka tūtaki ngā kairangahau hanga matū ki ngā arai hangarau noa. Ko ngā matū kore-ionic e whakamahia ana ko rātou anake ka iti te ātete ki te electrolyte, ā, ka puta pea te wehenga hinu, te wehewehe rānei i raro i te rokiroki pāmahana teitei, pāmahana iti rānei. Mena ka whakawhirinaki noa ngā kaihanga matū ki ngā emulsifier anionic, kāore e ranea te mahi whakamakuku me te urunga ki te whakapai ake i te whakatakotoranga pesticides ki ngā hua whainga. Ko te nui o te pahuka e puta ana i te wā e whakaoho ana, e whakararuraru ana hoki i te pai o te whakaputanga. He maha ngā kaihanga e hoko ana i ngā monomer maha mō te whakaranu i roto i te whare, ka hua ake he rārangi hoko rauemi mata whānui, he roa ake ngā huringa patuiro hanga matū me te nui o te mōrearea o te rerekētanga o te mahi puranga-ki-puranga, ka piki ake ngā utu R&D me te whakahaere kounga. Kei te hiahia nui te mākete ki tētahi tāpiringa whakaranu katoa-i-te-kotahi e whakauru ana i ngā mahi emulsification, dispersion, makuku me te urunga ki te whakahaere i te whanaketanga hanga matū me te pupuri i te pumau rokiroki mo te wā roa me te whai huatanga pono o te mara.
I runga i ngā tau maha o te wheako kua kohia ki te hanga matū horoi, i whakamahia e te tīma R&D o Qixuan te pūnaha whakakotahitanga anionic-nonionic. He maha ngā wāhanga o te whakataurite HLB, ngā whakamātautau rokiroki wera, ngā whakamātautau huringa tio-rewa, ngā aromatawai pumau wai mārō me ngā whakamātautau mākū rau i whakahaerehia, ā, i arotauhia ngā ōwehenga wāhanga kia oti ai tēnei tāpiringa whakaranu. Engari i te whakaranu tinana noa o ngā rauemi mata e toru, ka whakawhirinaki te hua ki ngā hononga ā-kanohi i waenga i ngā ngota hei hanga i tētahi kiriata ā-kanohi me te pakari teitei me te whakatutuki i te whakaurunga mahi maha-mahi.
He rerekē te mahi a ngā wāhanga matua e toru, ā, he rite tonu te hua o ēnei mahi ki te mahi tahi.
Ko te hinu kātoro ethoxylate te poutokomanawa matua o te pūnaha emulsifying non-ionic, he monomer mahi pakari e whakamahia whānuitia ana i roto i ngā āwhina pesticides. Ko tōna mekameka ngako roa i ahu mai i te hinu kātoro he tino pai te lipophilicity me te hototahitanga pai ki ngā rauemi hangarau pesticides hinu. Ko ngā wāhanga Polyoxyethylene e whakarato ana i ngā rōpū hydrophilic me te mahi i ngā mahi emulsification me te dispersion nui, e whakaiti ana i te taumahatanga interfacial hinu-wai me te whakauru i ngā rauemi hangarau hinu-wāhanga hei hanga i ngā emulsions ōrite. Ka tukuna hoki e ia he mahi makuku me te horapa tino pai hei whakahaere i te horapa wai ki runga i ngā mata rau hua. Ki te whakatauritea ki ngā ethoxylates waipiro ngako tuku iho, he whānui ake te manawanui pāmahana o te hinu kātoro ethoxylate me te urutau pH whānui. He hototahi ki ngā kai hohe maha e hangai ana ki te hinu tae atu ki ngā organophosphates me ngā pyrethroids, e whakatakoto ana i te turanga pakari mo te pūnaha tāpiri katoa.
Ko te poraka polyether butyl EO-PO te mea hei whakanui i te mahi. Mā tōna hanganga poraka EO-PO ka taea te whakarerekē i te HLB ngāwari, ā, mā te rōpū pito butyl ka whakawhiwhia te hua ki te kaha uru motuhake. I roto i ngā pūnaha whakapūhui, ka arotau i te hanganga kiriata ā-kanohi me te whakapai ake i te ātete kutikuti, kia ātete ai ngā whakapūhui i te whakakorenga i te wā e whakaoho ana, e whakakī ana me te waimeha i te wāhi. I roto i ngā āhuatanga rehu mara, ka whakaiti i te taumahatanga mata wai, ka whakatairanga i te urunga o ngā kai hohe mā roto i ngā kiriuhi tipu, ka whakanui ake i te pai o te mimiti me te whakapai ake i te whai huatanga o te whakahaere mara. I taua wā, he iti te pahuka o tēnei poraka polyether, ka pehi i te whakaputa pahuka i te wā e hanga ana me te rehu ana, ka whakakore i te hiahia mō ngā tango pahuka tāpiri me te whakangawari i ngā tohutao whakatakotoranga.
Ko te konupūmā dodecylbenzenesulfonate, e mōhiotia whānuitia ana ko te Agricultural Emulsifier 500#, he emulsifier anionic matarohia, ā, he wāhanga nui o tēnei pūnaha whakaranu. Ko tōna mekameka alkylbenzene lipophilic e piri ana ki te wāhanga hinu, ko ngā rōpū hydrophilic konupūmā sulfonate ka hanga i ngā kiriata atanga pumau i roto i te wāhanga wai. Ko te whakakotahitanga o ngā surfactants anionic me te non-ionic he huarahi hangarau kua whakamātauhia pai i roto i te emulsification pesticides. I muri i te whakaranu, ka eke te kiriata atanga ki te pakari teitei ake, ā, ko tōna ātete ki te wai mārō me ngā electrolytes he nui ake i ngā tāpiringa wāhanga-kotahi. Ina werohia e te wai mara pakeke-teitei me ngā poke mai i ngā rauemi hangarau, ka ātete te pūnaha ki te demulsification me te stratification, ka whakapai ake i te rokiroki wera me te pumau pāmahana-iti o ngā hanganga me te whakarite i te mahi pumau o te wā-papa.
Mā te whakaurunga o ngā mahi maha ka whakawhiwhia tēnei tāpiri ranu ki ngā painga matua e whā mō te whakamahinga.
Tuatahi, he pai ake te pumau o te emulsion. I whakamanahia e ngā whakamātautau rokiroki wera me te huringa huka-rewa, ka whakaatuhia e te emulsion te rahi matūriki ōrite, ā, ka ātete ki te wehenga hinu, te wehewehenga me te flocculation. He pai mō ngā kukū emulsiable (EC), ngā emulsions hinu-i-roto-i-te-wai (EW), ngā microemulsions (ME), ā, ka taea hoki te whakauru ki roto i ngā whakatakotoranga kukū whakatārewatanga (SC) kua tohua, e kapi ana i ngā whakaritenga whanaketanga whakatakotoranga matua o ngā kaihanga.
Tuarua, he tino pai te ātete ki te wai mārō me te hototahi whānui. He pai te urutau ki ngā momo matū hohe o ngā patu pepeke hinu. Ka paku rerekē te mahi whakapūkara i raro i ngā pūtake wai o ngā momo pakeke, ka whakaiti i te mōrearea o te whai huatanga kore pumau i puta mai i te kounga wai o te mara.
Tuatoru, te whakamakuku me te urunga hei whakarei ake i te whai huatanga. Ka whakaitihia te kukū o te mata wai, ka whakaitihia te rere o ngā pata ki runga i ngā rau ware pi pērā i te kāpeti me te citrus, ka whakanui ake i te whakatakotoranga o ngā kai hohe, ka whakapakari i te urunga, ā, ka tautoko i ngā kiritaki ki te whakaiti i ngā patu pepeke me te whakapai ake i te whai huatanga.
Tuawhā, te tuku kua rite te whakatakoto hei whakahaere i ngā kaihoko'te whakahaere hanganga. Kāore e hiahiatia ana e ngā umanga hanganga te hoko i ngā monomer maha mō te whakaranu i te papaanga, te whakaiti i ngā kāwai rarangi rauemi mata, te whakapoto i ngā huringa whanaketanga hanganga me te karo i ngā mōrearea rerekētanga puranga e puta mai ana i te whakaranu o roto. Ka taea hoki e Qixuan Chemical te whakarato i te whakatikatika hanganga me te tautoko i ngā ratonga hangarau e ai ki ngā kiritaki.'ngā momo matū hohe me ngā whakaritenga hanganga.
