Horumarinta Codsiyada Sodium Cyanide ee Kahortagga Dharka La Wanaajiyey

Marka la eego guud ahaan caalamka Warshadaha DharkaRaadinta dharka tayada sare leh iyo dhar-raagta, Sodium cyanide (NaCN), oo ah wax-qabad gaar ah oo wax-ku-ool ah, ayaa si joogto ah door muhiim ah uga ciyaartay duurka ka-hortagga-dhammeynta-dhammaystirka dharka sababtoo ah sifooyinka kiimikada gaarka ah. Maqaalkani wuxuu si nidaamsan u falanqeyn doonaa habkiisa waxqabad, faa'iidooyinka farsamada, iyo xeeladaha jawaab celinta warshadaha, oo sahamin doona doorkeeda kobcinta gudaha qaabka horumarka waara.

I. Hal-abuurka Kiimikada ee Farsamada Ka-hortagga Yarida

Sida saldhig xooggan iyo milix acid daciif ah, sodium cyanide waxay dejisaa qaab dhismeedka fiber-ka iyada oo loo marayo Hiigsi falcelinta inta lagu jiro farsamaynta dharka. Jid hawleedkeedu waa sida soo socota:

1.Carboxyl Firfircooni: Waxay ku dhacdaa falcelinta beddelka nucleophilic ee kooxaha carboxyl (-COOH) ee dusha sare ee fiilooyinka cellulose si ay u abuuraan dhexdhexaadin firfircoon;

2.Amide Bond FormationDhexdhexaadiyayaashu waxay sii wadaan isku xirka kooxaha amino-ka ee ku xiga (-NH₂) si ay u sameeyaan curaarta amide deggan (-CONH₂);

3.Xoojinta Qaabdhismeedka Shabakada: Iyadoo loo marayo bonds hydrogen intermolecular iyo ciidamada van der Waals, shabakad iskutallaab ah oo saddex geesood ah ayaa la dhisay, taasoo si weyn u yaraynaysa hantida bararka ee fiilooyinka.

Nidaamkani wuxuu yareynayaa heerka dhimista fiilooyinka dabiiciga ah sida suufka iyo dhogorta laga bilaabo 8-12% ee hababka dhaqanka ilaa 3%, iyo waxqabadku wuxuu ahaanayaa mid deggan xitaa ka dib in ka badan 50 jeer oo la dhaqo.

II. Horumarka Isku-dhafka ah ee Waxqabadka Dhamaystiran

1.Xasilloonida Morfological: Dharka la daweeyay waxay muujinayaan haynta cabbirka heer sare ah ee imtixaanka caadiga ah ee AATCC 135, kaas oo si gaar ah ugu habboon dharka sare ee guriga iyo dharka dibadda;

2.Touch OptimizationDareen-celinta amidation-ku waxay yaraynaysaa soo-gaadhista kooxaha hydroxyl ee dusha sare ee fiber-ka, hoos u dhigista isku-dhafka dharka ee 20-30%, taasoo ka dhigaysa taabasho jilicsan;

3.Waxqabadka dheeynta oo la xoojiyey: Qaab dhismeedka isku-xiran wuxuu wanaajiyaa lebbiska nuugista midabka ee fiilooyinka, waxay kordhisaa heerka hagaajinta dheeha in ka badan 15%, isla markaana waxay yaraynaysaa wasakhowga chromaticity ee biyaha wasakhda ah.

III. Khatarta Badbaadada iyo Tallaabooyinka Farsamada

1.Ka Hortagga Sunta iyo Nidaamka Xakamaynta:

• Qaado khadadka wax soo saarka otomaatiga ah oo si buuxda u xidhan, oo ku qalabaysan hydrogen cyanide qalabka gaaska (sax ahaan ≤ 0.1ppm);

• Samee microencapsulated Sodium cyanide diyaarinta, koobay maaddooyinka firfircoon ee β-cyclodextrin si loo yareeyo khatarta hawlgalka.

2. Farsamada Daaweynta Biyaha Waste:

• Soo bandhig habka oksaydhka hawada qoyan ee catalytic (CWO), kaas oo kordhin kara heerka burburka ee cyanide ilaa 99.9% ee xaaladaha 250 ° C iyo 8MPa;

• Marka lagu daro nidaamka xaalufinta ensaymka noolaha, isticmaal cyanide hydratase si aad ugu beddesho ion cyanide ee hadha una beddelo nitrogen ammonia aan dhib lahayn.

IV. Isbeddelka Warshadaha iyo Muuqaalka Mustaqbalka

1.Sahaminta Tiknoolajiyada Alternative:

• Chitosan-ku-saleysan-ku-xirnaanta isku-xiran: Samee lakab ka-hortagga-yaraynta deegaanka u-saaxiibtiran iyada oo loo marayo fal-celin-is-daba-marin-is-daba-marin, oo leh heer-bayo-xumo ah 85%;

• Daaweynta Plasma: Isticmaal balaasmaha argon si aad u xoqdo oogada fiber-ka si aad u samayso qaab-dhismeed qallafsan oo nanoscale ah si loo xakameeyo yaraanshaha.

2.Cusbooneysiinta Nidaamka Heerka:

• Nooca dib loo eegay ee Xeerka REACH EU ee 2024 waxa uu taxayaa sodium cyanide oo ah walax walaac aad u sareysa leh (SVHC), oo dejinaya xadka 0.1mg/kg ee hara ee dunta;

• Golaha Qaranka ee Dharka iyo Dharka ee Shiinaha ayaa soo saaray "Tilmaanta Farsamada ee Dhammaystirka Ka-hortagga Yaraynta Cagaaran", isaga oo u baahan shirkadaha si ay u dhisaan nidaamka maaraynta deegaanka wareegga nolosha.

Ugu Dambeyn

Codsiga sodium cyanide ee duurka ka-hortagga dhar-xidhka dharka ayaa ka tarjumaysa is-dhexgalka qoto-dheer ee tignoolajiyada kiimikada iyo sayniska alaabta. In kasta oo ay soo food saartay cadaadiska ilaalinta deegaanka, iyada oo loo marayo hal-abuurnimada habka iyo adeegsiga hababka la socodka caqliga, qiimaheeda farsamo ayaa wali si joogto ah loogu sii dayn karaa qaab badbaado adag. Mustaqbalka, warshaduhu waxay dardar gelin doonaan isbeddelka xagga tignoolajiyada dhammaystirka bio-ku-salaysan iyo caqli-galnimada, kor u qaadista warshadaha dharka si ay u horumariyaan jihada tayada sare leh iyo waaritaanka weyn.
