Ukuthuthukisa Izicelo Ze-Sodium Cyanide Zokunqanda Ukuncipha Kwendwangu Ethuthukisiwe

Esimweni somhlaba jikelele Umkhakha WezindwanguUkuphishekela izindwangu ezisebenza kahle nezihlala isikhathi eside, I-Sodium Cyanide (I-NaCN), njengesengezo esisebenzayo esikhethekile, iye yadlala indima ebalulekile ngokuqhubekayo emkhakheni wokuqeda ukushwabana kwendwangu ngenxa yezakhiwo zayo zamakhemikhali eziyingqayizivele. Lesi sihloko sizohlaziya ngendlela ehlelekile indlela yokusebenza kwayo, izinzuzo zobuchwepheshe, namasu okuphendula imboni, futhi ihlole ukuvela kwendima yayo ngaphakathi kohlaka lwentuthuko esimeme.

I. Ukuqamba Okusha Kwamakhemikhali Endleleni Yokulwa Nokuncipha

Njengesisekelo esiqinile nosawoti we-asidi ebuthakathaka, i-sodium cyanide uzinzisa ukwakheka fibre ngokusebenzisa Amidation ukusabela ngesikhathi sokucubungula izindwangu. Umgomo wayo oyinhloko umi kanje:

1.Carboxyl Activation: Ibhekana ne-nucleophilic substitution reaction namaqembu e-carboxyl (-COOH) ebusweni bemicu ye-cellulose ukuze kukhiqizwe okuphakathi okusebenzayo;

2.Amide Bond Formation: Abaphakathi baqhubeka nokuxhumanisa namaqembu e-amino aseduze (-NH₂) ukuze bakhe amabhondi ama-amide azinzile (-CONH₂);

3.Ukuqiniswa Kwesakhiwo Senethiwekhi: Nge-intermolecular hydrogen bond kanye namandla e-van der Waals, inethiwekhi enezinhlangothi ezintathu exhunywe ngokuphambana iyakhiwa, kunciphisa kakhulu indawo yokuvuvukala kwemicu.

Le nqubo inciphisa izinga lokushwabana kwemicu yemvelo efana ukotini noboya kusuka ku-8-12% ezinqubweni zendabuko kuya ngaphansi kuka-3%, futhi ukusebenza kuhlala kuzinzile ngisho nangemva kwezikhathi ezingaphezu kuka-50 zokugeza.

II. I-Synergistic Ukuthuthukiswa Kokusebenza Okuphelele

1.Ukuzinza kwe-Morphological: Izindwangu ezilashiwe zibonisa ukugcinwa kwe-dimensional okuhle kakhulu ekuhlolweni okujwayelekile kwe-AATCC 135, efaneleka ngokukhethekile izindwangu zasekhaya ezisezingeni eliphezulu nezimpahla zangaphandle;

2.Ukuthuthukisa Ukuthinta: Ukusabela kwe-amidation kunciphisa ukuvezwa kwamaqembu e-hydroxyl endaweni yefayibha, kunciphisa i-coefficient yokungqubuzana kwendwangu ngo-20-30%, okwenza ukuthinta kube bushelelezi;

3.Ukusebenza Okuthuthukisiwe Kokudaya: Isakhiwo esixhumene nesiphambano sithuthukisa ukufana kokumuncwa kombala kwemicu, kwandisa izinga lokulungisa udayi ngaphezu kuka-15%, futhi ngesikhathi esifanayo kunciphisa ukungcoliswa kwe-chromaticity kwamanzi angcolile.

III. Izingozi Zokuphepha kanye Nezinyathelo Zokulwa Nezobuchwepheshe

1.Isistimu Yokuvimbela Nokulawula Ubuthi:

• Yamukela imigqa yokukhiqiza ezenzakalelayo evalwe ngokugcwele, efakwe i-hydrogen i-cyanide izitholi zegesi (ukunemba ≤ 0.1ppm);

• Thuthukisa i-microencapsulated I-sodium cyanide amalungiselelo, hlanganisa izithako ezisebenzayo ku-β-cyclodextrin ukunciphisa izingozi zokusebenza.

2.Wastewater Treatment Technology:

• Yethula inqubo ye-catalytic wet air oxidation (CWO), engakhuphula izinga lokubola kwe-cyanide liye ku-99.9% ngaphansi kwezimo ezingu-250°C kanye ne-8MPa;

• Ngokuhambisana nohlelo lokuwohloka kwe-enzyme yebhayoloji, sebenzisa i-cyanide hydratase ukuguqula ama-ion asele e-cyanide abe yi-ammonia nitrogen engenangozi.

IV. Uguquko Lwemboni kanye Nekusasa Le-Outlook

1.Ukuhlola Alternative Technologies:

• Ama-agent axhumanisa ama-cross-link ase-Chitosan: Yakha ungqimba oluvikela ukushwabana kwemvelo ngokusabela kwe-graft copolymerization, ngezinga lokuwohloka kwemvelo lama-85%;

• Ukwelashwa kwe-Plasma: Sebenzisa i-argon plasma ukuze unamathisele i-fiber surface ukuze wakhe isakhiwo esimahhadlahhadla esingalinganisa ukuvimbela ukuncipha.

2.Ukuthuthukiswa Kwesistimu Ejwayelekile:

• Inguqulo ebuyekeziwe ye-EU REACH Regulation ngo-2024 ibala i-sodium cyanide njengento ekhathazayo kakhulu (SVHC), ibeka umkhawulo oyinsalela ongu-0.1mg/kg wezindwangu;

• I-China National Textile and Apparel Council ikhiphe "Ukucaciswa Kwezobuchwepheshe Kwe-Green Anti-Shrinkage Finishing", edinga amabhizinisi ukuthi asungule uhlelo lokulawulwa kwemvelo lomjikelezo wempilo.

Isiphetho

Ukusetshenziswa kwe-sodium cyanide emkhakheni we-textile anti-shrinkage kukhombisa ukuhlanganiswa okujulile kobuchwepheshe bamakhemikhali kanye nesayensi yezinto. Naphezu kokubhekana nezingcindezi zokuvikelwa kwemvelo, ngokusebenzisa inqubo emisha kanye nokusetshenziswa kwezinhlelo zokuqapha ezihlakaniphile, inani layo lobuchwepheshe lisengakwazi ukukhishwa ngokuqhubekayo ngaphakathi kohlaka oluqinile lokuphepha. Ngokuzayo, imboni izosheshisa uguquko oluya kubuchwepheshe bokuqedela obusekelwe ku-bio kanye nobuhlakani bokuqedela, ukukhuthaza imboni yendwangu ukuthi ithuthuke ngendlela yekhwalithi ephezulu kanye nokusimama okukhulu.
