Ukuqhubela phambili kwezicelo zeSodium Cyanide zokuphucula i-Team Textile Antishrinkage

Kwimeko yehlabathi Imveliso yeLtileUkusukela ukusebenza okuphezulu kunye nempahla ehlala ixesha elide, Isodium cyanide (I-NaCN), njengesongezo esikhethekileyo esisebenzayo, iqhubekile idlala indima ebalulekileyo kwibala lokunqanda ukushwabana kokugqiba ngenxa yeekhemikhali zayo ezizodwa. Eli nqaku liza kuhlalutya ngokucwangcisiweyo indlela yokusebenza kwayo, izibonelelo zobugcisa, kunye nezicwangciso zokuphendula kwishishini, kwaye liphonononge indima yalo yendaleko kwisakhelo sophuhliso oluzinzileyo.

I. Utshintsho lweMichiza kwi-Anti-Shrinkage Mechanism

Njengesiseko esomeleleyo kunye netyuwa ebuthakathaka yeasidi, sodium cyanide uzinzisa isakhiwo ifayibha ngokusebenzisa Amidation ukusabela ngexesha lokwenziwa kwelaphu. Undoqo wendlela yayo yile ilandelayo:

1.Carboxyl Activation: Ifumana i-nucleophilic substitution reaction kunye namaqela e-carboxyl (-COOH) kumphezulu we-cellulose fibers ukuvelisa i-intermediates esebenzayo;

2.Amide Bond Formation: I-intermediates iqhubela phambili i-cross-link kunye namaqela e-amino akufutshane (-NH₂) ukwenza iibhondi ezizinzileyo ze-amide (-CONH₂);

3.Ukomelezwa koLwakhiwo lweNethiwekhi: Ngokusebenzisa iibhondi ze-hydrogen ze-intermolecular kunye ne-van der Waals imikhosi, i-network-dimensional-dimensional cross-linked network yakhiwe, ukunciphisa kakhulu ipropati yokuvuvukala kweefayili.

Le nkqubo inciphisa izinga lokucutheka kwemicu yendalo efana nekotoni kunye noboya ukusuka kwi-8-12% kwiinkqubo zemveli ukuya ngaphantsi kwe-3%, kwaye ukusebenza kuhlala kuzinzile nasemva kwamaxesha angaphezu kwama-50 okuhlamba.

II. UPhuculo lweSynergistic lokuSebenza ngokuBanzi

1.Uzinzo lweMorphological: Amalaphu aphathwayo abonisa ukugcinwa kwe-dimensional egqwesileyo kuvavanyo oluqhelekileyo lwe-AATCC 135, olufanelekileyo ngokukhethekileyo kwimpahla yasekhaya ephezulu kunye nempahla yangaphandle;

2.UkuSebenzisa ukuTouch: Ukusabela kwe-amidation kunciphisa ukuvezwa kwamaqela e-hydroxyl kwi-fiber surface, ukunciphisa i-coefficient ye-friction yelaphu ngama-20-30%, okwenza ukuba umnxeba ube lula;

3.Ukwenziwa koMsebenzi oPhuhliweyo wokuDaya: Isakhiwo esidibeneyo siphucula ukufana kombala we-fibers, ukwandisa izinga lokulungiswa kwedayi ngaphezu kwe-15%, kwaye kwangaxeshanye kunciphisa ukungcoliswa kwe-chromaticity yamanzi amdaka.

III. Imingcipheko yoKhuseleko kunye neMilinganiselo yobuGcisa yokuNqanda

1.Inkqubo yoThintelo lweToxicity kunye noLawulo:

• Yamkela imigca yemveliso evalelwe ngokupheleleyo, exhotyiswe ngehydrogen i-cyanide izixhobo zegesi (ukuchaneka ≤ 0.1ppm);

• Phuhlisa i-microencapsulated Isodium cyanide amalungiselelo, faka izithako ezisebenzayo kwi-β-cyclodextrin ukunciphisa ingozi yokusebenza.

2.ITekhnoloji yoNyango lwamanzi amdaka:

• Yazisa inkqubo ye-catalytic wet air oxidation (CWO), enokunyusa izinga lokubola kwe-cyanide ukuya kuma-99.9% phantsi kweemeko ze-250 ° C kunye ne-8MPa;

• Idityaniswe nenkqubo yokuthotywa kwe-enzyme yebhayoloji, sebenzisa i-cyanide hydratase ukuguqula iiyoni ezishiyekileyo ze-cyanide zibe yi-ammonia nitrogen engenabungozi.

IV. INguqu yoShishino kunye neNkalo yekamva

1.Uphononongo lweeTechnologies ezizezinye:

• I-Chitosan-based cross-linking agents: Yenza umaleko wokuchasana nokushwabana okusingqongileyo ngokusabela kwegrafti ye-copolymerization, kunye nesantya se-biodegradation ye-85%;

• Unyango lwePlasma: Sebenzisa i-argon plasma ukuze udibanise umphezulu wefiber ukwenza i-nanoscale rough structure ukuthintela ukushwabana.

2.Ukuphuculwa kweNkqubo yoMgangatho:

• Uhlaziyo oluhlaziyiweyo lwe-EU REACH Regulation ngo-2024 ludwelisa i-sodium cyanide njengento exhalabisa kakhulu (SVHC), ibeka umda oshiyekileyo we-0.1mg/kg kwizinto ezilukiweyo;

• I-China National Textile and Apparel Council ikhuphe i-"Technical Specification for Green Anti-Shrinkage Finishing", ifuna ukuba amashishini aseke inkqubo yolawulo lokusingqongileyo kumjikelo wobomi.

isiphelo

Ukusetyenziswa kwe-sodium cyanide kwintsimi ye-textile anti-shrinkage ibonisa ukuhlanganiswa okunzulu kwetheknoloji yekhemikhali kunye nesayensi yezinto. Nangona ujongene noxinzelelo lokukhusela okusingqongileyo, ngokusebenzisa inkqubo entsha kunye nokusetyenziswa kweenkqubo zokubeka iliso ezihlakaniphile, ixabiso layo lobugcisa lisenokukhutshwa ngokuqhubekayo ngaphakathi kwesakhelo esingqongqo sokhuseleko. Kwixesha elizayo, ishishini liza kukhawulezisa inguqu kwi-bio-based kunye nobuchwephesha bokugqiba ubukrelekrele, ukukhuthaza ushishino lwamalaphu ukuba luphuhlise kwicala lomgangatho ophezulu kunye nozinzo olukhulu.
