Sodium Cyanide: Zofunika Kwambiri Zopangira Mankhwala

Udindo Wosiyanasiyana wa Sodium Cyanide: Lupanga Lakuthwa Pawiri Pamafakitale

Sodium cyanide, pawiri yodziwika bwino chifukwa cha kawopsedwe kwambiri, nthawi zambiri imawonedwa kudzera m'maso mwanzeru ndi nkhawa. Komabe, kupitilira chikhalidwe chake chowopsa, Sodium cyanide imagwira ntchito ngati gawo lofunikira mumitundu yosiyanasiyana Mapulogalamu a mafakitale, kuwonetsa gawo lake losasinthika m'magawo kuyambira asatayike ku Nsalu ndi Pachikuz. Nkhaniyi ikufotokoza za kagwiritsidwe ntchito kosiyanasiyana kwa Sodium Cyanide, kuwonetsa kufunikira kwake kwinaku akuvomereza kuopsa kwachibadwa kokhudzana ndi kagwiridwe kake ndi kagwiritsidwe ntchito.

1. Sodium Cyanide mu Pharmaceutical Production

Chimodzi mwazinthu zodziwika kwambiri za sodium cyanide ali m'makampani opanga mankhwala, makamaka mu kaphatikizidwe ka barbiturates ndi sulfonamides. Ma barbiturates, omwe kale ankatchulidwa kwambiri ngati mankhwala ogonetsa komanso ogona, asiya kukondedwa chifukwa chopanga njira zina zotetezeka. Komabe, amakhalabe ndi gawo lazachipatala, makamaka ngati mankhwala oletsa matenda enaake akupha, monga organochlorine mankhwala endosulfan, komanso kasamalidwe ka neonatal kernicterus.

Kupanga kwa diethyl malonate, chinthu chofunikira kwambiri pakupanga ma barbiturates, kumadalira kwambiri sodium cyanide. M'mafakitale, sodium cyanide imagwiritsidwa ntchito limodzi ndi sodium chloroacetate kupanga sodium fluoroacetate, yomwe pambuyo pake imayikidwa ndi ethanol kuti itulutse diethyl malonate. Njira yamankhwala iyi imatsimikizira kufunika kwa sodium cyanide mu gawo lazamankhwala, komwe imathandizira kupanga mankhwala omwe ali ndi chithandizo chofunikira kwambiri.

2. Sodium Cyanide mu Kupanga Zovala

Pankhani ya nsalu, sodium cyanide imagwira ntchito yofunika kwambiri popanga ulusi wopangira. Malinga ndi malipoti aposachedwa, ulusi wopangira umakhala pafupifupi 70% ya ulusi wonse wansalu womwe umapangidwa ku China, chiwerengero chomwe chikuwonetsa kufunikira kwa zinthu izi m'magwiritsidwe osiyanasiyana, kuyambira mafashoni mpaka ku mafakitale. Kukonza pafupifupi ulusi wonse wopangidwa kumafuna kugwiritsa ntchito sodium cyanide ngati zopangira.

Kusinthasintha kwa ulusi wopangidwa, womwe umaphatikizapo poliyesitala, nayiloni, ndi acrylic, kwapangitsa kuti ikhale yofunika kwambiri pamakampani opanga nsalu. Udindo wa sodium cyanide m'gawoli ndi wofunikira, chifukwa umathandizira pakupanga mankhwala omwe amasintha zopangira kukhala ulusi womwe umapangidwa kukhala nsalu. Kudalira kwa sodium cyanide pakupanga nsalu kumawonetsa kufunikira kwa chigawochi kuposa mbiri yake yapoizoni, kuwonetsa zofunikira zake pokwaniritsa zofuna zamalonda amakono.

3. Sodium Cyanide mu Electroplating

Ntchito ina yofunika kwambiri ya sodium cyanide ndi m'munda wa electroplating, komwe imagwiritsidwa ntchito kupititsa patsogolo kuyika kwazitsulo monga golide ndi siliva. Mu electroplating, sodium cyanide imapanga ma ion ovuta ndi zitsulo zomwe zimakutidwa, zomwe zimapangitsa kuti pakhale ma ion zitsulo a cyanide. Njirayi ndiyofunikira kuti mukwaniritse zomaliza zamtundu wa electroplated.

Ubwino wogwiritsa ntchito ayoni zitsulo za cyanide monga ma electrolyte mu electroplating ndizochulukirapo. Pamene ma ion aulere azitsulo zomatidwa amagwiritsidwa ntchito mwachindunji, kuchuluka kwa ma deposition kumatha kukhala okwera kwambiri, zomwe zimapangitsa kuti pakhale filimu yotayirira komanso yaporous yomwe ilibe kumatira koyenera komanso kukhazikika. Mosiyana ndi zimenezi, kugwiritsa ntchito sodium cyanide kumapangitsa kuti pakhale ndondomeko yoyendetsedwa bwino, zomwe zimapangitsa kuti zikhale zowuma komanso zokutira zofanana. Izi ndizofunikira makamaka pamagwiritsidwe omwe kukongola ndi magwiridwe antchito a malo opukutidwa ndizofunikira kwambiri.

Kuphatikiza apo, ntchito ya sodium cyanide ngati ligand mu electroplating imathandizidwa ndi kuthekera kwake kukhazikika ma ayoni achitsulo muyankho, kupewa kugwa kwamvula msanga komanso kuonetsetsa kuti plating imakhazikika. Chikhalidwechi chimakhala chopindulitsa makamaka pazitsulo zomwe zimakhala ndi oxidation kapena zowonongeka zina panthawi ya plating.

4. Kuganizira za Chitetezo ndi Zachilengedwe

Ngakhale kufunikira kwake kwa mafakitale, kugwiritsa ntchito sodium cyanide kuli ndi zoopsa zambiri. Kuchuluka kwake kawopsedwe kumadzetsa ngozi kwa ogwira ntchito komanso chilengedwe. Kukhudzana ndi sodium cyanide kungayambitse poizoni woopsa, ndi zizindikiro zoyambira mutu ndi chizungulire mpaka kulephera kupuma ndi imfa. Chifukwa chake, malamulo okhwima otetezedwa ndi malamulo ndiofunikira m'mafakitale omwe amagwiritsa ntchito mankhwalawa.

M'zaka zaposachedwa, pakhala kugogomezera kwambiri kufunikira kwa njira zina zotetezeka komanso kuwongolera machitidwe owongolera m'mafakitale omwe amadalira sodium cyanide. Makampani akupanga ndalama zambiri pofufuza kuti akhazikitse zolowa m'malo zomwe zili ndi poizoni komanso kukhazikitsa njira zodzitetezera kuti ziteteze ogwira ntchito komanso kuchepetsa kuwonongeka kwa chilengedwe. Vuto lagona pakulinganiza ubwino wa zinthu zapadera za sodium cyanide ndi kufunikira koteteza thanzi la anthu komanso chilengedwe.

5. Kutsiliza

Sodium cyanide ndi mankhwala ovuta omwe ali ndi kuthekera kotukuka kwa mafakitale komanso kufunikira kosamala. Kugwiritsa ntchito kwake muzamankhwala, nsalu, ndi ma electroplating kukuwonetsa ntchito yake yosasinthika pakupanga kwamakono. Komabe, zoopsa zomwe zimachitika ndi sodium cyanide sizinganyalanyazidwe. Pamene mafakitale akupitilira kukula, cholinga chiyenera kukhalabe pakuwonetsetsa kuti njira zotetezeka zikugwiritsidwa ntchito pogwiritsa ntchito phindu la gulu lamphamvuli.

Pomaliza, sodium cyanide imakhala ngati chikumbutso cha mitundu iwiri ya mankhwala ambiri omwe amagwiritsidwa ntchito m'makampani-okhoza kuyendetsa zatsopano ndi kupita patsogolo pomwe amakhalanso ndi chiopsezo chachikulu. Vuto lomwe likupitilira kwa opanga, owongolera, ndi ofufuza ndikuyendetsa bwino izi, kuwonetsetsa kuti mapindu a sodium cyanide atha kukwaniritsidwa popanda kusokoneza chitetezo kapena kukhulupirika kwa chilengedwe. Pamene tikupita patsogolo, kudzipereka pakugwiritsa ntchito moyenera komanso kuwongolera mosalekeza njira zotetezera kudzakhala kofunikira pakuthandizira zabwino za sodium cyanide ndikuchepetsa kuopsa kwake.
