Ukuqhubela phambili kwezicelo zeSodium Cyanide zokuphucula i-Team Textile Antishrinkage

Kwimeko yokufuna kweShishini leeMpahla kwihlabathi liphela iilaphu ezisebenza kakuhle nezihlala ixesha elide, iSodium Cyanide (NaCN), njengesithako esikhethekileyo esisebenzayo, idlale indima ebalulekileyo kwicandelo lokugqitywa kwelaphu ngenxa yeempawu zayo ezikhethekileyo zeekhemikhali. Eli nqaku liza kuhlalutya ngokucwangcisiweyo indlela yokusebenza kwalo, iingenelo zobugcisa, kunye namaqhinga okuphendula kushishino, kwaye lihlolisise uphuhliso lwendima yalo ngaphakathi kophuhliso oluzinzileyo.

I. Utshintsho lweMichiza kwi-Anti-Shrinkage Mechanism

Njengesiseko esomeleleyo kunye netyuwa ye-asidi ebuthathaka, i-sodium cyanide izinzisa isakhiwo sefayibha nge- Amidation reaction ngexesha lokucubungula ilaphu. Indlela yayo eyintloko yokusebenza yile ilandelayo:

1. Ukusebenza kweCarboxyl : Ifumana impendulo yokutshintshwa kwe-nucleophilic kunye namaqela e-carboxyl (-COOH) kumphezulu weefayibha ze-cellulose ukuze ivelise ii-intermediates ezisebenzayo;

2. Ukwakheka kwe-Amide Bond : Ezi ziphakathi zidibanisa amaqela e-amino akufutshane (-NH₂) ukuze zenze ii-amide bonds ezizinzileyo (-CONH₂);

3. Ukuqinisa ulwakhiwo lweNethiwekhi : Ngokusebenzisa iibhondi zehydrogen eziphakathi kweemolekyuli kunye namandla e-van der Waals, kwakhiwa inethiwekhi edibeneyo enamacala amathathu, nto leyo enciphisa kakhulu ipropati yokudumba kweefayibha.

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 lweMofological : Amalaphu aphathweyo abonisa ukugcinwa okugqwesileyo kobukhulu kuvavanyo oluqhelekileyo lwe-AATCC 135, olufaneleke ngokukodwa kwimpahla yasekhaya ephezulu kunye neempahla zangaphandle;

2. Ukuphucula ukuchukumisa : I-amidation reaction inciphisa ukuvezwa kwamaqela e-hydroxyl kumphezulu wefayibha, inciphisa i-friction coefficient yelaphu ngama-20-30%, okwenza ukuchukumisa kube lula;

3. Ukusebenza Kokudaya Okuphuculweyo : Isakhiwo esidityaniswe ngomgca siphucula ukufunxwa kombala kweefayibha, sonyusa izinga lokufakwa kwedayi ngaphezulu kwe-15%, kwaye kwangaxeshanye sinciphisa ungcoliseko lwe-chromaticity lwamanzi amdaka.

III. Imingcipheko yoKhuseleko kunye neMilinganiselo yobuGcisa yokuNqanda

1. Inkqubo yoThintelo noLawulo lweTyhefu :

• Sebenzisa imigca yemveliso ezenzekelayo evalekileyo ngokupheleleyo, exhotyiswe nge-hydrogen cyanide gas detectors (ukuchaneka ≤ 0.1ppm);

• Phuhlisa amalungiselelo e -Sodium cyanide afakwe i-microcapsulated , faka izithako ezisebenzayo kwi-β-cyclodextrin ukunciphisa iingozi zokusebenza.

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. Ukuhlola iiTekhnoloji 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 esemgangathweni :

• 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.
