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

N'ihe gbasara mbọ ụlọ ọrụ mmepụta ákwà zuru ụwa ọnụ na-agba iji mee ka ákwà dị elu ma na-adịgide adịgide, Sodium Cyanide (NaCN), dịka ihe mgbakwunye ọrụ pụrụ iche, na-arụ ọrụ dị mkpa mgbe niile n'ihe gbasara imecha ákwà mgbochi ịda mbà n'obi n'ihi ihe kemịkalụ pụrụ iche ya. Isiokwu a ga-enyocha usoro ọrụ ya, uru teknụzụ, na atụmatụ nzaghachi ụlọ ọrụ n'ụzọ zuru oke, ma nyochaa mgbanwe ọrụ ya n'ime usoro mmepe na-adịgide adịgide.

I. Kemịkalụ ọhụrụ n'ime usoro mgbochi mgbochi

Dịka ntọala siri ike na nnu asịd na-adịghị ike, sodium cyanide na-eme ka nhazi eriri ahụ sie ike site na mmeghachi omume Amidation n'oge nhazi ákwà. Isi ọrụ ya bụ dịka ndị a:

1. Mmelite Carboxyl : Ọ na-eme mgbanwe mgbanwe nucleophilic na otu carboxyl (-COOH) n'elu eriri cellulose iji mepụta etiti na-arụ ọrụ;

2. Nhazi Njikọta Amide : Ndị etiti na-ejikọ njikọ na otu amino dị n'akụkụ (-NH₂) iji mepụta njikọ amide kwụsiri ike (-CONH₂);

3. Ime ka usoro netwọk sikwuo ike : Site na njikọ hydrogen dị n'etiti molekul na ike van der Waals, a na-ewu netwọk nwere akụkụ atọ, na-ebelata nke ukwuu ihe gbasara ịba ụba nke eriri ndị ahụ.

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. Ịkwụsi ike n'ọdịdị : Ákwà ndị a gwọrọ na-egosipụta njide akụkụ dị mma na ule AATCC 135 ọkọlọtọ, nke dabara adaba karịsịa maka ákwà ụlọ dị elu na uwe dị n'èzí;

2. Mmezi Mmetụ Aka : Mmeghachi omume amidation na-ebelata ikpughe nke otu hydroxyl n'elu eriri ahụ, na-ebelata oke esemokwu nke ákwà ahụ site na 20-30%, na-eme ka mmetụ ahụ dị nro;

3. Arụmọrụ agba agba ka mma : Nhazi njikọ cross-connected na-eme ka nha nhata agba nke eriri dị na agba dịkwuo mma, na-eme ka ọnụego agba agba dịkwuo elu karịa 15%, ma n'otu oge ahụ na-ebelata mmetọ chromaticity nke mmiri mkpofu.

III. Ihe egwu nchekwa na usoro nka nka

1. Sistemụ Mgbochi na Njikwa Nsí :

• Jiri ahịrị mmepụta akpaaka nke ejiri ihe nchọpụta gas hydrogen cyanide mee ihe (nke ziri ezi ≤ 0.1ppm);

• Mepụta nkwadebe Sodium cyanide nke nwere obere ihe mkpuchi , tinye ihe ndị dị na β-cyclodextrin iji belata ihe egwu ọrụ.

2. Teknụzụ Ọgwụgwọ Mmiri Mkpofu :

• 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. Nchọgharị nke Teknụzụ Ndị Ọzọ :

• 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. Mmelite nke Sistemụ Ọkọlọtọ :

• 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.
