I-Reactive Dyeing inesimo esihle kakhulu sokuncibilika emanzini.Odayi abasebenzayo ikakhulukazi bathembele eqenjini le-sulfonic acid ku-molecule kadayi ukuze bancibilike emanzini.Odayi abasebenzayo be-meso-temperature abaqukethe amaqembu e-vinylsulfone, ngaphandle kwamaqembu e-sulfonic acid Ngaphezu kwalokho, i-β-ethylsulfone sulfate yayo futhi iyiqembu elihle kakhulu lokuqedwa.Esixazululweni esinamanzi, ama-ion e-sodium eqenjini le-sulfonic acid kanye neqembu -ethylsulfone sulfate abhekana ne-hydration reaction ukuze enze udayi wakhe i-anion futhi uncibilike emanzini.Ukudaywa kodayi abasebenzayo kuncike kuma-ion angalungile odayi azodaywa ku-fiber.Ukuncibilika kodayi abasebenzayo kudlula 100 g/L.
I-solubility yamadayi amaningi yi-200-400 g/l, kanti abanye odayi bangafinyelela ku-450 g/l.
Kodwa enqubo yokudaya, ukuncibilika kwedayi kuzokwehla ngenxa yezizathu ezihlukahlukene (noma ngisho nokungancibiliki ngokuphelele).
Lapho ukuncibilika kwedayi kuncipha, ingxenye yedayi izoshintsha isuka ku-ion eyodwa yamahhala ibe yizinhlayiya, futhi ukuhoxiswa kwecala phakathi kwezinhlayiya kuncipha kakhulu.
Izinhlayiya nezinhlayiya zizodonselana ukuze zakhe i-agglomeration
Kulolu hlobo lokuhlanganisa, izinhlayiya zikadayi zihlangana zibe ama-aggregate, bese ziba ama-aggregate, futhi ekugcineni zibe ama-flocs.Nakuba i-floc iyiqoqo elixekethile, ngenxa yesendlalelo esiphindwe kabili kagesi esakhiwe ngamashaji amahle nabi azungezile, kunzima ukuthi amandla okugunda otshwala obujwayelekile bodayi awuchithe, futhi i-floc ilula kalula kwendwangu.Imvula ngaphezulu, okuholela ekungcoleni noma ekungcoleni.
Uma udayi usunenhlanganisela enjalo, ukushesha kombala kuzokwehla ngokusobala, futhi kuzobangela amazinga ahlukene amabala, amabala, namabala.Kwamanye amadayi, ama-flocs azoqhubekisela phambili ukusheshisa umhlangano ngaphansi kwe-shear force yotshwala obudayi, okubangela ukuphelelwa amandla kwamanzi kanye nosawoti ngaphandle.Uma usawoti usuphumile, umbala odayiwe uzokhanya ngokwedlulele, noma ungadayiwe, noma ngabe udayiwe, kuzoba amabala amnyama namabala.
Ukudaya Okusebenzayo
Izimbangela zokuhlanganisa udayi
Isizathu esiyinhloko yi-electrolyte.Enqubweni yokudaya, i-electrolyte eyinhloko yi-accelerant yodayi (i-sodium sulphate powder nosawoti).I-accelerant yodayi iqukethe ama-ion e-sodium, kanti i-sodium ion elingana ne-molecule kadayi iphansi kakhulu kunaleyo ye-accelerant yedayi.Inombolo elinganayo ye-sodium ion kanye nokugxila okuvamile kwe-accelerator ngesikhathi senqubo evamile yokudaya ngeke kube nethonya elikhulu ekuncibilikeni kwedayi ekugezeni okudayi.
Kodwa-ke, lapho inani le-ejenti ekhuthaza udayi landa, ukugcwala kwe-sodium ion esixazululweni nakho kuyanda.I-ion ye-sodium eyeqile izovimbela i-ionization ye-sodium ion emaqenjini ancibilikile ama-molecule edayi, ngaleyo ndlela kunciphise ukuncibilika kwedayi.
Uma ukugxila kokusheshisa udayi kudlula u-200 g/L, odayi abaningi bazothola amazinga ahlukene wokuhlanganisa.
Uma ukugxila kokusheshisa udayi kudlula u-200 g/L, odayi abaningi bazothola amazinga ahlukene wokuhlanganisa.
Lapho ukugxila kwe-ejenti ekhuthaza udayi kudlula u-250 g/L, izinga lokuhlanganisa lizoqina, kuqala kwakheke ama-agglomerate, bese kwakheka ngokushesha ama-agglomerates kanye nama-floccules ngaphansi kwamandla okugunda ekhambi likadayi.Kwabanye odayi abanokuncibilika okuphansi, Ingxenye yabo ikhishwa usawoti futhi iphelelwe amanzi emzimbeni.
Amadayi anezinhlaka ezihlukene zamangqamuzana ane-anti-aggregation ehlukene kanye nokumelana nosawoti.Ukuncipha kokuncibilika, kuba kubi kakhulu ukumelana nokuhlanganiswa kanye nokuphuma kukasawoti.
Ukuncibilika kwedayi ikakhulukazi kunqunywa inani lamaqembu e-sulfonic acid ku-molecule kadayi kanye nenani lama-β-ethylsulfone sulfate.
Ngesikhathi esifanayo, i-hydrophilicity ye-molecule kadayi inkulu, i-solubility ephezulu, futhi i-hydrophilicity ephansi, i-solubility ephansi.(Isibonelo, odayi abanesakhiwo se-azo bangama-hydrophilic kakhulu kunamadayi anesakhiwo se-heterocyclic.) Ngaphezu kwalokho, uma udayi umkhulu, ukuncipha kokuncibilika, kanye nesakhiwo samangqamuzana, kukhuphuka ukuncibilika.
Singabahlinzeki beReactive Dyeing.Uma unesidingo semikhiqizo yethu, sicela ukhululeke ukuxhumana nathi.
