Kusimudzira Sodium Cyanide Zvikumbiro zveEnhanced Textile Antishrinkage

Mukutsvaga kweIndasitiri yeMachira yepasi rose machira anoshanda zvakanaka uye anogara kwenguva refu, Sodium Cyanide (NaCN), sechinhu chinobatsira zvikuru, yakaramba ichiita basa rakakosha mumunda wekugadzirisa machira nekuda kwehunhu hwayo hwemakemikari. Chinyorwa chino chichaongorora mashandiro ayo, zvakanakira zvehunyanzvi, uye nzira dzekupindura kumaindasitiri, uye kuongorora kushanduka kwebasa rayo mukati mehurongwa hwebudiriro inoenderera mberi.

I. Chemical Innovation muAnti-Shrinkage Mechanism

Sehwaro hwakasimba uye munyu usina acid, sodium cyanide inosimbisa chimiro chefiber kuburikidza neAmidation reaction panguva yekugadzirisa machira. Nzira yayo huru yekuita ndeiyi inotevera:

1. Kushanda kweCarboxyl : Inoita seyakachinja nucleophilic substitution reaction nemapoka ecarboxyl (-COOH) pamusoro pefibers dzecellulose kuti igadzire active intermediates;

2. Kuumbwa kweAmide Bond : Zvinobatanidza zvinobatana nemapoka emaamino ari pedyo (-NH₂) kuti zvigadzire maamide bonds akagadzikana (-CONH₂);

3. Kusimbiswa kweMagadzirirwo eNetwork : Kuburikidza nepakati pemahydrogen bonds uye van der Waals forces, network ine mativi matatu inogadzirwa, zvichideredza zvakanyanya kuzvimba kwemafibers.

Iyi nzira inoderedza shrinkage yehuwandu hwemafiber echisikigo akadai sekotoni nemvere dzemakwai kubva pa8-12% mumagariro echinyakare kusvika pasi pe3%, uye kushanda kunoramba kwakagadzikana kunyange mushure menguva dzinopfuura makumi mashanu dzekugeza.

II. Synergistic Kuvandudza Kwekuita Kwakazara

1. Kugadzikana kweMagadzirirwo : Machira akagadzirwa anoratidza kugadzikana kwakanaka mukuyedzwa kweAATCC 135 kwakajairika, uko kwakakodzera zvakanyanya machira epamba epamusoro uye zvipfeko zvekunze;

2. Kugadzirisa Kubata: Kuita kwe amidation kunoderedza kuratidzwa kwemapoka e hydroxyl pamusoro pe fiber, zvichideredza friction coefficient yejira ne20-30%, zvichiita kuti kubata kuite nyore;

3. Kushanda Kwakanaka Kwekudhaya : Chimiro chakabatana chinovandudza kufanana kwemavara eshinda, chinowedzera mwero wekuisa dhayi neinopfuura 15%, uye panguva imwe chete chinoderedza kusvibiswa kwemvura yakasviba ne chromaticity.

III. Kuchengetedza Njodzi uye Technical Countermeasures

1.Sisitimu yekudzivirira uye kudzora chepfu :

• Shandisa mitsetse yekugadzira yakagadzirwa otomatiki yakavharirwa zvizere, ine hydrogen cyanide gas detectors (kururama ≤ 0.1ppm);

• Gadzirai mishonga yeSodium cyanide yakavharirwa muzvikamu zvidiki , sanganisai zvinhu zvinoshanda zviri muβ-cyclodextrin kuti muderedze njodzi dzekushanda kwemishonga.

2. Tekinoroji yekurapa mvura yakasviba :

• Taurira iyo catalytic wet air oxidation process (CWO), iyo inogona kuwedzera decomposition rate ye cyanide kusvika 99.9% pasi pemamiriro e250 ° C uye 8MPa;

• Yakabatana neiyo biological enzyme degradation system, shandisa cyanide hydratase kushandura yasara cyanide ayoni kuita isingakuvadze ammonia nitrogen.

IV. Shanduko yeindasitiri uye Remangwana Outlook

1.Kutsvaga Matekinoroji Anogona Kushandiswa :

• Chitosan-based cross-linking agents: Gadzirai nharaunda inochengetedza shrinkage layer kuburikidza negraft copolymerization reactions, ine biodegradation rate ye85%;

• Kurapa kwePlasma: Shandisa argon plasma kuisa fiber pamusoro kuti iite nanoscale rough chimiro kuti inhibit shrinkage.

2. Kuvandudzwa kweStandard System :

• Shanduro yakadzokororwa yeEU REACH Regulation muna 2024 inonyora sodium cyanide sechinhu chinonyanya kunetsa (SVHC), ichiisa muganho wasara we0.1mg/kg kumachira;

• China National Textile and Apparel Council yakapa "Technical Specification yeGreen Anti-Shrinkage Finishing", inoda kuti mabhizinesi atange hupenyu hwekutenderera kwemamiriro ekunze.

mhedziso

Kushandiswa kwe sodium cyanide mumunda we textile anti-shrinkage kunoratidza kubatanidzwa kwakadzama kwemakemikari tekinoroji nesainzi yemidziyo. Kunyangwe kutarisana nedzvinyiriro yekuchengetedzwa kwezvakatipoteredza, kuburikidza nekuvandudza maitiro uye nekushandiswa kweakangwara ekutarisa masisitimu, kukosha kwayo kwehunyanzvi hunogona kuramba kuburitswa mukati meiyo yakasimba kuchengetedza. Mune ramangwana, indasitiri inomhanyisa shanduko yakananga kubio-based uye nehungwaru kupedzisa matekinoroji, kusimudzira indasitiri yemachira kuti ikure munzira yemhando yepamusoro uye kusimudzira kukuru.
