Ngwa Sodium Cyanide na-aga n'ihu maka mgbochi mgbochi akwa akwa

N'ọnọdụ nke ụwa Industrylọ ọrụ akwaỊchụso akwa dị elu na nke na-adịte aka, sodium cyanide (NaCN), dị ka ihe mgbakwunye na-arụ ọrụ pụrụ iche, na-aga n'ihu na-arụ ọrụ dị mkpa n'ọhịa nke imecha ihe mgbochi mgbochi n'ihi njirimara kemịkalụ ya pụrụ iche. Edemede a ga-enyocha usoro ya n'usoro, uru teknụzụ, yana atụmatụ nzaghachi ụlọ ọrụ, wee nyochaa mgbanwe ọrụ ya n'ime usoro mmepe mmepe.

I. Kemịkalụ ọhụrụ n'ime usoro mgbochi mgbochi

Dị ka isi siri ike na nnu acid na-adịghị ike, sodium cyanide na-eme ka usoro eriri ahụ guzosie ike site na Amidation mmeghachi omume n'oge nhazi textile. Ụzọ ọrụ ya bụ isi bụ nke a:

1.Carboxyl arụ ọrụ: Ọ na-enweta mmeghachi omume nucleophilic ngbanwe ya na ndị otu carboxyl (-COOH) n'elu eriri cellulose iji mepụta ndị na-arụ ọrụ n'etiti;

2.Amide Bond Formation: Ndị etiti na-aga n'ihu na njikọ amino dị n'akụkụ (-NH₂) iji mepụta njikọ amide kwụsiri ike (-CONH₂);

3.Mmesi ike nke Network Structure: Site intermolecular hydrogen bonds na van der Waals agha, a na-arụ a atọ akụkụ cross-njikọ netwọk na-ebelata n'ụzọ dị ukwuu na ọzịza ihe onwunwe nke eriri.

Usoro a na-ebelata mbelata nke eriri ndị sitere n'okike dị ka owu na ajị si 8-12% na usoro ọdịnala ruo n'okpuru 3%, na arụmọrụ na-adịgide adịgide ọbụlagodi mgbe ịsachara ihe karịrị ugboro 50.

II. Mmekọrịta mmekọrịta nke arụmọrụ zuru oke

1.Morphological Stability: Ihe ndị a na-edozi ahụ na-egosipụta njide akụkụ dị mma na ọkọlọtọ AATCC 135, nke dị mma maka akwa ụlọ dị elu na uwe n'èzí;

2.Touch Optimization: Mmeghachi omume amidation na-ebelata ikpughe nke ìgwè hydroxyl n'elu eriri, na-ebelata ọnụ ọgụgụ esemokwu nke ákwà site na 20-30%, na-eme ka mmetụ ahụ dịkwuo nro;

3.Enwekwara arụmọrụ dyeing: Usoro ejikọtara ọnụ na-eme ka ọdịdị ahụ dị n'otu nke eriri ahụ dịkwuo mma, na-eme ka ọnụ ọgụgụ na-edozi ihe dị elu karịa 15%, ma n'otu oge ahụ na-ebelata mmetọ chromaticity nke mmiri mkpofu.

III. Ihe egwu nchekwa na usoro nka nka

1.Mgbochi na-egbu egbu na Sistemụ Njikwa:

• Nabata ahịrị mmepụta akpaaka emechiela nke ọma, nwere hydrogen cyanide ndị na-achọpụta gas (ezigbo ≤ 0.1ppm);

• Mepụta microencapsulated sodium cyanide nkwadebe, tinye ihe ndị na-arụ ọrụ na β-cyclodextrin iji belata ihe egwu arụ ọrụ.

2.Teknụzụ ọgwụgwọ mmiri mmiri:

• Ewebata catalytic wet air oxidation process (CWO), nke nwere ike ime ka ọnụọgụ nke cyanide dị elu ruo 99.9% n'okpuru ọnọdụ 250 ° C na 8MPa;

• Ejikọtara ya na sistemu mmebi enzyme nke ndu, jiri cyanide hydratase mee ka ion cyanide fọdụrụnụ ghọọ amonia nitrogen na-adịghị emerụ ahụ.

IV. Mgbanwe ụlọ ọrụ na Outlook Ọdịnihu

1.Exploration nke Alternative Teknụzụ:

• Ndị na-emekọ ihe na-ejikọta Chitosan: Mepụta oyi akwa mgbochi mgbochi na gburugburu ebe obibi site na mmeghachi omume copolymerization graft, yana ọnụego biodegradation nke 85%;

• Ọgwụgwọ Plasma: Jiri plasma argon na-ekepụta elu eriri ka ọ mepụta usoro siri ike nanoscale iji gbochie mbelata.

2.Upgrading nke Standard System:

• Ụdị EU REACH Regulation nke edegharịrị na 2024 depụtara sodium cyanide dị ka ihe nwere oke nchegbu (SVHC), na-esetịpụ njedebe nke 0.1mg/kg maka akwa akwa;

• Kansụl National Textile and Apparel Council ewepụtala "Nka na ụzụ nka maka Green Anti-Shrinkage Finishing", chọrọ ka ụlọ ọrụ guzobe usoro nlekọta gburugburu ebe obibi usoro ndụ.

mmechi

Ngwa nke sodium cyanide na ngalaba mgbochi mgbochi textile na-egosipụta njikọ miri emi nke teknụzụ kemịkal na sayensị ihe. N'agbanyeghị na-eche nrụgide nchebe gburugburu ebe obibi ihu, site na mmepụta usoro na ntinye nke usoro nlekota nke ọgụgụ isi, uru ọrụ ya ka nwere ike ịhapụ ya n'ihu n'ihu n'ime usoro nchekwa siri ike. N'ọdịnihu, ụlọ ọrụ ahụ ga-eme ka mgbanwe ahụ dịkwuo elu na teknụzụ mmecha nke bio-based na ọgụgụ isi, na-akwalite ụlọ ọrụ textile ka ịzụlite n'ụzọ nke ịdị elu dị elu na nkwado dị ukwuu.
