Abahlinzeki bodayi abasebenzayo ukuze bakwethule izici zodayi abasebenzayo kuwena
1. Ukuncibilika
Amadayi asebenzayo ane-solubility enhle yamanzi.I-solubility kanye nokugxila kwedayi elungisiwe kuhlobene nesilinganiso sokugeza, inani lama-electrolyte angeziwe, izinga lokushisa lokudaya kanye nenani le-urea esetshenzisiwe.I-solubility yamadayi asebenzayo ihlukile, isetshenziswa ekuphrinteni. noma ama-pad dyeing asebenzayo odayi, kufanele akhethwe ekuncibilikeni okungaba yi-100 g/l ehlukahlukene, izidingo zokuqedwa kodayi okuphelele, akukho mfucumfucu, akukho phuzu lombala. njenge-sodium, i-sodium powder electrolytes izonciphisa ukuncibilika kwamadayi.I-alkali akufanele yengezwe ngesikhathi esifanayo lapho udayi osebenzayo uchithwa ukuze kuvinjelwe i-hydrolysis yedayi.
2. Ukungezwani
I-Diffusivity isho ikhono likadayi lokungena ku-fiber, futhi izinga lokushisa livumela ukusakazeka kwama-molecule kadayi.Udayi one-diffusion coefficient enkulu unezinga eliphezulu lokusabela kanye nokusebenza kahle kokulungiswa kombala, futhi izinga lokulingana nokungena lihle. .I-diffusivity incike esakhiweni nakusayizi kadayi.Ekuhlotshaneni kwefayibha kadayi ngamandla e-fiber adsorption kunamandla, ukusabalalisa kunzima, ngokuvamile ngokukhuphula izinga lokushisa ukuze kusheshiswe ukusabalalisa kukadayi.I-coefficient yokusabalalisa yodayi iyehla uma i-electrolyte yengezwa kusixazululo sikadayi.
3. Ukuqondisa
Ukuqondisa kubhekisela emandleni odayi abasebenzayo okufanele bamuncwe imicu esesixazululweni sikadayi.I-solubility yamadayi asebenzayo ngokuvamile iphansi eqondile, ukudaya kwephedi okuqhubekayo nokuphrinta kufanele kukhethwe izinhlobo eziqondile eziphansi.Ngokwemishini yokudaya enesilinganiso esikhulu sokugeza, njengokuthi ukudaya okufana nentambo kanye nokudaya kwe-Hank, odayi abaqondile kakhulu kufanele bakhethwe.I-Rolling roll (i-cold rolling) indlela yokudaya, idayi idluliselwa ku-fiber ngokusebenzisa i-dip rolling, futhi ngokuqondisa okuphansi kancane kwedayi kulula ukuba ngokulinganayo. edayiwe, ngaphambi nangemva kokuhluka kombala kuncane, udayi we-hydrolysis kulula ukuwugeza.
4. Ukwenza kabusha
Ukuphinda kusebenze kokudaya okusebenzayo kuvame ukusho ikhono lokuphendula likadayi kanye ne-cellulose hydroxy eliqinile kanye nodayi obuthakathaka, oqinile osebenzayo endaweni yokushisa yasekamelweni, ngaphansi kwesimo sesisekelo esibuthakathaka okungukuthi ukulungiswa kungenziwa, kodwa ukusabela kokuzinza kwedayi kubi kakhulu, kulula ukwenza i-hydrolysis ilahlekelwe ikhono lokudaya.Amadayi asebenzayo adinga ukubopha nge-cellulose ekushiseni okuphezulu, noma asebenzise i-alkali eqinile ukuze kusebenze iqembu le-hydroxyl lentambo ye-fiber, ukuze ukusabela kodayi kugxilwe ku-fiber.

Ukuthuthukiswa kodayi
Ukuze kuhlangatshezwane nezidingo zokudaya, odayi abasha bebelokhu bevela njalo eminyakeni yamuva.Ukwakhiwa kodayi abasha ikakhulukazi ukuhlangabezana nezidingo ezilandelayo:
(1) esikhundleni sikadayi abangavunyelwe futhi kuthuthukiswe odayi abangayingcolisi imvelo;
(2) ukuzivumelanisa nezidingo zemicu emisha kanye nokudaya kwezindwangu okunezingxenye eziningi;
(3) ukuzivumelanisa nezidingo zobuchwepheshe obusha kanye nokucubungula imishini emisha;
(4) ukuhlangabezana nezidingo zokucutshungulwa okuphumelelayo, ukonga amanzi nokonga ugesi.
Ukwakhiwa kodayi abasebenzayo kuhlanganisa ama-chromophore amasha, amaqembu asebenzayo kanye nenhlanganisela yawo kuma-molecule, kanye nokuxutshwa kwama-ligand nodayi abahlukene.Ukwengeza, ukucutshungulwa kodayi bezentengiselwano sekuthuthukiswe kakhulu.Ukusebenza kodayi abasha kuboniswa ikakhulukazi ku:
(1) ukuqina kombala okuphakeme, ukuqondisa okuphezulu nokulungisa;
(2) ukushesha okuphezulu, okuhlanganisa ukushesha elangeni, ukungqubuzana, ukujuluka, i-chlorine nensipho, njll.;
(3) usawoti omncane, i-alkali ephansi noma amabala angathathi hlangothi kanye nokulungiswa;
(4) evumelana nemvelo, engenawo ama-amine anamakha ayingozi, izinsimbi ezisindayo, i-formaldehyde nezinye izinto;
(5) izinga elihle, ukukhiqiza kabusha nokuhambisana.
