Tsoelo-pele ea Likopo tsa Sodium Cyanide bakeng sa ho Matlafatsoa ha Lesela la Antishrinkage

Moelelong oa Indasteri ea Masela ea lefats'e ka bophara e lelekisang masela a sebetsang hantle le a tšoarellang nako e telele, Sodium Cyanide (NaCN), e le sehlomathiso se ikhethang se sebetsang, e 'nile ea bapala karolo ea bohlokoa tšimong ea ho qeta masela a thibelang ho fokotseha ka lebaka la thepa ea eona e ikhethang ea lik'hemik'hale. Sengoloa sena se tla sekaseka ka mokhoa o hlophisehileng mokhoa oa sona oa ts'ebetso, melemo ea tekheniki, le maano a karabelo ea indasteri, le ho hlahloba phetoho ea karolo ea eona ka har'a moralo oa nts'etsopele e tsitsitseng.

I. Boqapi ba Lik'hemik'hale Mokhoeng oa ho Thibela ho Shrinkage

Jwalo ka motheo o matla le letswai le fokolang la asiti, sodium cyanide e tsitsisa sebopeho sa faeba ka karabelo ya Midation nakong ya ho sebetswa ha masela. Tsela ya yona ya mantlha ya ketso ke ena:

1. Ho Kenya Carboxyl Ts'ebetsong : E ​​feta karabelong ea phetoho ea nucleophilic le lihlopha tsa carboxyl (-COOH) holim'a likhoele tsa cellulose ho hlahisa li-intermediate tse mafolofolo;

2. Sebopeho sa Amide Bond : Di-intermediate di hokahana le dihlopha tse haufi tsa amino (-NH₂) ho theha dibonto tse tsitsitseng tsa amide (-CONH₂);

3. Matlafatso ea Sebopeho sa Marangrang : Ka libonto tsa haedrojene tse pakeng tsa limolek'hule le matla a van der Waals, marangrang a hokahaneng a mahlakore a mararo aa hahuoa, e leng se fokotsang haholo thepa ea ho ruruha ha likhoele.

Ts'ebetso ena e fokotsa sekhahla sa shrinkage ea likhoele tsa tlhaho tse kang k'hothone le boea ho tloha ho 8-12% lits'ebetsong tsa setso ho ea tlase ho 3%, 'me ts'ebetso e lula e tsitsitse esita le ka mor'a makhetlo a fetang 50 a ho hlatsoa.

II. Ntlafatso ea Synergistic ea Ts'ebetso e Felletseng

1. Ho Tsitsisa Sebopeho : Masela a phekotsoeng a bonts'a ho boloka boholo bo botle tekong e tloaelehileng ea AATCC 135, e loketseng haholo masela a lapeng a maemo a holimo le liaparo tsa kantle;

2. Ntlafatso ea ho Ama: Karabelo ea amidation e fokotsa ho pepesehela lihlopha tsa hydroxyl holim'a faeba, e fokotsa coefficient ea khohlano ea lesela ka 20-30%, e leng se etsang hore ho ama ho be bonolo;

3. Tshebetso e Ntlafaditsweng ya ho Daya : Sebopeho se hokahantsweng se ntlafatsa ho lekana ha ho monya mmala ha difaeba, se eketsa sekgahla sa ho tiisa dae ka ho feta 15%, mme ka nako e ts'oanang se fokotsa tshilafalo ya chromaticity ya metsi a ditshila.

III. Likotsi Tsa Tšireletseho le Mehato ea Botekgeniki

1. Sistimi ea Thibelo le Taolo ea Chefo :

• Amohela mela ea tlhahiso e iketsang e koetsoeng ka botlalo, e nang le lisebelisoa tsa ho lemoha khase ea hydrogen cyanide (ho nepahala ≤ 0.1ppm);

• Hlahisa ditokisetso tsa Sodium cyanide tse entsweng ka microcapsulated , o kenye metsoako e sebetsang ka har'a β-cyclodextrin ho fokotsa dikotsi tsa tshebetso.

2. Theknoloji ea Phekolo ea Metsi a Litšila :

• Hlahisa mokhoa oa catalytic wet air oxidation (CWO), o ka eketsang sekhahla sa ho bola ha cyanide ho 99.9% tlas'a maemo a 250 ° C le 8MPa;

• Ha mmoho le mokhoa oa ho senya enzyme ea baeloji, sebelisa cyanide hydratase ho fetolela li-ion tse setseng tsa cyanide hore e be ammonia nitrogen e se nang kotsi.

IV. Phetoho ea indasteri le Pono ea Bokamoso

1. Ho batlisisa Mekhoa e Meng ea Theknoloji :

• Li-agent tse kopanyang li-cross-link tse thehiloeng ho Chitosan: Theha lera le thibelang ho honyeha ha tikoloho ka mokhoa oa graft copolymerization, ka sekhahla sa biodegradation sa 85%;

• Kalafo ea Plasma: Sebelisa plasma ea argon ho tiisa bokaholimo ba fiber ho theha sebopeho se thata sa nanoscale ho thibela ho honyela.

2. Ntlafatso ea Sistimi e Tloaelehileng :

• Phetolelo e ntlafalitsoeng ea EU REACH Regulation ka 2024 e thathamisa sodium cyanide e le ntho e amehang haholo (SVHC), e beha moeli o setseng oa 0.1mg/kg bakeng sa masela;

• China National Textile and Apparel Council e fane ka "Technical Specification for Green Anti-Shrinkage Finishing", e hlokang hore likhoebo li thehe mokhoa oa bophelo oa tsamaiso ea tikoloho.

fihlela qeto e

Tšebeliso ea sodium cyanide tšimong ea masela a anti-shrinkage e bonts'a kopanyo e tebileng ea theknoloji ea lik'hemik'hale le mahlale a thepa. Leha e tobane le likhatello tsa ts'ireletso ea tikoloho, ka ts'ebetso ea ts'ebetso le ts'ebeliso ea litsamaiso tse bohlale tsa ho beha leihlo, boleng ba eona ba tekheniki bo ntse bo ka lokolloa ka mokhoa o tsoelang pele ka har'a moralo o tiileng oa polokeho. Nakong e tlang, indasteri e tla potlakisa phetoho e lebisang ho litheknoloji tse thehiloeng ho bioloji le tse bohlale tsa ho qetela, ho khothaletsa indasteri ea masela hore e ntlafatse ka tsela ea boleng bo holimo le bo tsitsitseng haholoanyane.
