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

Boemong ba lefats'e Indasteri ea Lesela'ho phehella masela a sebetsang hantle le a tšoarellang nako e telele, Sodium cyanide (NaCN), e le tlatsetso e khethehileng e sebetsang, e 'nile ea tsoela pele ho phetha karolo ea bohlokoa tšimong ea ho qeta lesela le khahlanong le shrinkage ka lebaka la thepa ea eona e ikhethang ea lik'hemik'hale. Sengoliloeng sena se tla sekaseka ka tatellano mokhoa oa ts'ebetso, melemo ea tekheniki, le maano a karabelo ea indasteri, 'me se hlahlobe karolo ea eona ea ho iphetola ha lintho ka har'a moralo oa nts'etsopele ea moshoelella.

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

E le setsi se matla le letsoai le fokolang la acid, sodium cyanide tsitsisa sebopeho sa fiber ka ho Amidation karabelo nakong ea ts'ebetso ea masela. Mokhoa oa eona oa mantlha oa ts'ebetso ke o latelang:

1.Carboxyl Activation: E kenella karabelo ea nucleophilic substitution le lihlopha tsa carboxyl (-COOH) holim'a likhoele tsa cellulose ho hlahisa li-intermediate tse sebetsang;

2.Amide Bond Formation: Li-intermediate li tsoela pele ho hokahanya le lihlopha tsa amino tse haufi (-NH₂) ho theha li-amide bond tse tsitsitseng (-CONH₂);

3.Ho matlafatsa Sebopeho sa Marang-rang: Ka li-intermolecular hydrogen bonds le matla a van der Waals, marang-rang a mararo a marang-rang a marang-rang a hahoa, a fokotsa haholo thepa ea ho ruruha ea 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.Morphological Stability: Masela a ts'oaroang a bonts'a ho bolokoa ka mokhoa o babatsehang ka mokhoa o babatsehang oa tlhahlobo ea AATCC 135, e loketseng ka ho khetheha bakeng sa masela a phahameng a ntlo le liaparo tsa ka ntle;

2.Touch Optimization: Boitšoaro ba amidation bo fokotsa ho pepeseha ha lihlopha tsa hydroxyl holim'a fiber, ho fokotsa coefficient ea lesela ka 20-30%, ho etsa hore ho ama ho be bonolo;

3.Ts'ebetso e Ntlafetseng ea ho daea: Sebopeho se kopantsoeng le sefapano se ntlafatsa ho lumellana ha mebala ea likhoele, ho eketsa tekanyo ea ho lokisa dae ka ho feta 15%, 'me ka nako e ts'oanang e fokotsa tšilafalo ea chromaticity ea metsi a litšila.

III. Likotsi Tsa Tšireletseho le Mehato ea Botekgeniki

1.Toxicity Thibelo le Control System:

• Amohela mehala ea tlhahiso e koetsoeng ka botlalo, e nang le haedrojene cyanide lisebelisoa tsa khase (ho nepahala ≤ 0.1ppm);

• Hlahisa microencapsulated Sodium cyanide litokisetso, ho kenyelletsa metsoako e sebetsang ho β-cyclodextrin ho fokotsa likotsi tsa ts'ebetso.

2.Theknoloji ea ho hloekisa 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.Tlhahlobo ea Mahlale a Mang:

• 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.Nchafatso ea Tsamaiso ea Boemo:

• 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.
