Ukuthuthukisa Izicelo Ze-Sodium Cyanide Zokunqanda Ukuncipha Kwendwangu Ethuthukisiwe

Emongweni wokufuna kwemboni yezindwangu emhlabeni wonke izindwangu ezisebenza kahle nezihlala isikhathi eside, i-Sodium Cyanide (NaCN), njengesithako esikhethekile esisebenzayo, ibilokhu idlala indima ebalulekile emkhakheni wokuqedwa kwezindwangu ngenxa yezakhiwo zayo zamakhemikhali ezihlukile. Lesi sihloko sizohlaziya ngokuhlelekile indlela esebenza ngayo, izinzuzo zobuchwepheshe, kanye namasu okuphendula embonini, futhi sihlole ukuvela kwendima yayo ngaphakathi kohlaka lwentuthuko esimeme.

I. Ukuqamba Okusha Kwamakhemikhali Endleleni Yokulwa Nokuncipha

Njengesisekelo esinamandla kanye nosawoti we-asidi ebuthakathaka, i-sodium cyanide izinzisa isakhiwo se-fiber ngokusebenzisa ukusabela kwe-Amidation ngesikhathi sokucubungula indwangu. Indlela yayo eyinhloko yesenzo yile elandelayo:

1. Ukusebenza kwe-Carboxyl : Idlula ekusabeleni kokushintshana kwe-nucleophilic namaqembu e-carboxyl (-COOH) ebusweni bezintambo ze-cellulose ukuze ikhiqize ama-intermediate asebenzayo;

2. Ukwakheka kwe-Amide Bond : Ama-intermediate aqhubeka nokuxhumana namaqembu ama-amino aseduze (-NH₂) ukuze akhe izibopho ze-amide ezizinzile (-CONH₂);

3. Ukuqinisa Isakhiwo Senethiwekhi : Ngokusebenzisa izibopho ze-hydrogen eziphakathi kwama-molecule kanye namandla e-van der Waals, kwakhiwa inethiwekhi exhunywe ngezinhlangothi ezintathu, okunciphisa kakhulu isici sokuvuvukala 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 Kwesimo Semvelo : Izindwangu eziphathwe kahle zibonisa ukugcinwa okuhle kakhulu kobukhulu ekuhlolweni okujwayelekile kwe-AATCC 135, okulungele kakhulu izindwangu zasekhaya ezisezingeni eliphezulu kanye nezingubo zangaphandle;

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

3. Ukusebenza Okuthuthukisiwe Kokudaya : Isakhiwo esixhumene sithuthukisa ukufana kombala wemicu, sandisa izinga lokufakwa kodayi ngaphezu kuka-15%, futhi ngesikhathi esifanayo sinciphisa ukungcola kwe-chromaticity kwamanzi amdaka.

III. Izingozi Zokuphepha kanye Nezinyathelo Zokulwa Nezobuchwepheshe

1. Uhlelo Lokuvimbela Nokulawula Ubuthi :

• Sebenzisa imigqa yokukhiqiza ezenzakalelayo evalwe ngokuphelele, ifakwe izitholi zegesi ze-hydrogen cyanide (ukunemba ≤ 0.1ppm);

• Thuthukisa amalungiselelo e -Sodium cyanide afakwe i-microcapsulated , hlanganisa izithako ezisebenzayo ku-β-cyclodextrin ukuze unciphise izingozi zokusebenza.

2. Ubuchwepheshe Bokwelapha Amanzi Angcolile :

• 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 Ubuchwepheshe Obuhlukile :

• 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 kohlelo olujwayelekile :

• 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.
