intshayelelo

Sodium i-cyanide (I-NaCN), ikhompawundi ye-inorganic, inoluhlu olubanzi lwezicelo kuwo wonke amashishini ahlukeneyo nangona indalo yayo enetyhefu kakhulu. Kwi Ishishini leplastiki, Isodium cyanide idlala iindima ezibalulekileyo kwiinkqubo ezahlukeneyo, inegalelo ekuvelisweni kwezinto ezahlukeneyo zeplastiki kunye neemveliso.

Ukuveliswa kweePlastiki zangaphambili

I-Adiponitrile Synthesis yeMveliso yeNyiloni

Enye yezicelo ezibalulekileyo ze Isodium cyanide kwishishini leplastiki kwimveliso ye Adiponitrile, esisandulela esingundoqo se Inayiloni 6.6 - ifayibha yokwenziwa esetyenziswa ngokubanzi kwicandelo leplastiki. Inkqubo ibandakanya ukuveliswa kwehydrogen cyanide ukusuka sodium cyanide. I-Hydrogen cyanide ke ithatha inxaxheba kuthotho lweempendulo ukwenza i-adiponitrile. Ngokukhula kwemfuno yenayiloni kumzi mveliso wamalaphu kunye necandelo lemveliso yeemveliso ezahlukeneyo ezifana nempahla, iikhaphethi, kunye neendawo zemoto, imfuno ye-adiponitrile, kwaye ngenxa yoko, i-sodium cyanide, iyanda. Ngokomzekelo, ekuveliseni amabhanti e-automotive high-quality, i-nylon 6.6 fibers, ephuma kwi-adiponitrile eveliswe ngokusebenzisa iinkqubo ezisekelwe kwi-sodium cyanide, zinika amandla afunekayo kunye nokuqina.

Ukuveliswa kwe-Acrylonitrile ye-Polyacrylonitrile (PAN)

I-sodium cyanide nayo ibandakanyeka kwimveliso ye-acrylonitrile, esetyenziselwa ukuvelisa i-polyacrylonitrile (PAN). I-PAN yipolymer ebalulekileyo enezicelo kwiindawo ezifana neentsinga zokwenziwa kushishino lwamalaphu nanjengesandulela semicu yekhabhoni. Kwimveliso ye-acrylonitrile, i-sodium cyanide - iikhemikhali eziphuma kwiikhemikhali zisabela kunye nezinye iikhompawundi ukwenza i-acrylonitrile monomer. Ezi monomers ke ngoko polymerized ukwenza polyacrylonitrile. Iintsinga zeCarbon ezenziwe ngePAN zinamandla amakhulu - ukuya kumlinganiselo wobunzima kwaye zisetyenziswa kumacandelo e-aerospace, izixhobo zemidlalo ezisebenza kakhulu, kunye nezixhobo eziphambili ezihlanganisiweyo.

NjengoNcedo lokuSabela

I-Catalysis kwi-Specific Polymerization Reactions

Kwiimpendulo ezithile zepolymerization kwishishini leplastiki, i-sodium cyanide inokusebenza njenge-catalyst okanye uncedo lokuphendula. Ngokomzekelo, kwezinye iinkqubo ze-polymerization ye-condensation apho amaqela athile asebenzayo kufuneka aphendule ukwenza amakhonkco e-polymer, i-sodium cyanide inokwenza lula ukusabela ngokukhuthaza ukusebenza kwee-reactants. Inokukunceda ekuphuleni nasekudaleni amabhondi ekhemikhali ngendlela ekhawulezisa inkqubo ye-polymerization, ekhokelela ekuveliseni ngokufanelekileyo kweeplastiki. Oku kuluncedo ngokukodwa kwimveliso yeeplastiki ezikhethekileyo apho ulawulo oluchanekileyo malunga nesantya sokusabela kunye nesakhiwo sepolymer sifunekayo. Ngokusebenzisa i-sodium cyanide njengoncedo lokuphendula, abavelisi banokufikelela ubunzima obufunwayo bemolekyuli kunye ne-polymer architecture ngempumelelo ngakumbi.

Ukuququzelela ukuguqulwa kweMichiza kwiPlastiki

I-sodium cyanide ingasetyenziselwa ukwazisa amaqela ekhemikhali athile okanye imisebenzi kwiipolima zeplastiki. Ngokusetyenziswa kweekhemikhali eziyilwe ngononophelo, iqela lecyanide elisuka kwisodium cyanide linokufakwa kumqolo wepolymer okanye amatyathanga asecaleni. Olu hlengahlengiso lunokutshintsha iipropathi zeplastiki, ezinjengokuphucula ukunyibilika kwayo, ukusebenza kwakhona, okanye iimpawu zokubambelela. Umzekelo, ekuveliseni izinto zokuncamathelisa ezithile ezisekwe kwiipolima zeplastiki, ukungeniswa kwamaqela aphuma kwi-cyanide kunokonyusa amandla okuncamathela okuncamathela kwii-substrates ezahlukeneyo, okwenza ukuba kusebenze ngakumbi kwizicelo ezinjengokubopha iinxalenye zeplastiki kwi-electronics okanye kumashishini eemoto.

Kwizinto eziKhethekileyo zokwenziwa kwePlastiki

Ukuveliswa kweSodium Ferrocyanide - iiPlastiki ezizinzile

I-sodium cyanide isetyenziselwa ukuveliswa kwe-sodium ferrocyanide, esebenza njenge-stabilizer kwiiplastiki. Iiplastiki ziyinxalenye ebalulekileyo yeemveliso ezininzi zamashishini kunye nabathengi, kwaye ukuzinza kwazo kubalulekile ekugcineni umgangatho wemveliso kunye nobomi. I-sodium ferrocyanide inceda ekuthinteleni ukuthotywa kweeplastiki ngenxa yezinto ezahlukeneyo ezinjengobushushu, ukukhanya, kunye nokuvezwa kweekhemikhali. Kwizicelo apho iiplastiki zichaneke kwiimeko ezinzima, ezifana nefenitshala yangaphandle, imibhobho yothutho lwekhemikhali, okanye izindlu zesixhobo sombane, ukusetyenziswa kwe-sodium ferrocyanide - iiplastiki ezizinzileyo, ezivumela ukusetyenziswa kwe-sodium cyanide kwinkqubo yayo yokuvelisa, iqinisekisa ukuba iimveliso zeplastiki zigcina ingqibelelo yazo yesakhiwo kunye nokusebenza kwexesha.

Igalelo kwiMveliso yePlasstiki yobuNjineli bokuSebenza okuPhezulu

Kwimveliso yeplastiki yobunjineli obuphezulu, eyenzelwe ukujamelana neemeko ezinzima ezifana nobushushu obuphezulu, uxinzelelo oluphezulu, kunye neendawo ezinobungozi, i-sodium cyanide inokudlala indima engathanga ngqo kodwa ebalulekileyo. Njengoko kukhankanyiwe ngaphambili, inegalelo kwimveliso yeemonomer eziphambili kunye noncedo lokuphendula olusetyenziswa ekudibaneni kwezi plastiki ziphambili. Ngokomzekelo, ekuveliseni i-polyetheretherketone (PEEK), esetyenziselwa kwi-aerospace, i-automotive, kunye nezicelo zonyango ngenxa yeempawu zayo ezigqwesileyo zokumelana neekhemikhali, inkqubo yokudibanisa eyinkimbinkimbi inokubandakanya amanyathelo axhomekeke kwiikhemikhali ezivela kwi-sodium cyanide. Nangona ukusetyenziswa ngokuthe ngqo kwe-sodium cyanide kwimveliso ye-PEEK isenokungabonakali, ikhonkco lonikezelo lweekhemikhali ngokubanzi elikhokelela ekuvelisweni kwee-PEEK monomers kunye nokulungiswa kwe-polymerization reactions kunokulandelwa emva kokusetyenziswa kwe-sodium cyanide kumanqanaba angaphambili okwenziwa kweekhemikhali.

Iingqwalasela zokusiNgqongileyo noKhuseleko

Ngelixa i-sodium cyanide ibalulekile kwishishini leplastiki, ubutyhefu bayo obugqithisileyo bufuna amanyathelo angqongqo okhuseleko kuzo zonke izigaba zokusetyenziswa kwayo, ukusuka kwimveliso ukuya ekulahlweni. Kwiindawo zokuvelisa iplastiki, iinkqubo ezifanelekileyo zokuphatha, ezifana nokusetyenziswa kwezixhobo zokukhusela zomntu, iindawo zokusebenza ezinomoya ococekileyo, kunye nokugcinwa okukhuselekileyo kwe-sodium cyanide, kubalulekile ukukhusela nayiphi na ingozi yengozi kubasebenzi. Ukongeza, iinkxalabo zokusingqongileyo malunga nokulahlwa kwenkunkuma enesodium cyanide okanye iimveliso zayo zibalulekile. Kukho imigaqo engqongqo yokuqinisekisa ukuba nayiphi na inkunkuma iphathwa ngokufanelekileyo ukuze kuthintelwe ukungcoliseka komhlaba, amanzi nomoya. Ukurisayikilisha kunye namanyathelo okunciphisa inkunkuma nawo ayaphononongwa ukuze kuncitshiswe impembelelo yokusingqongileyo eyayanyaniswa nokusetyenziswa kwesodium cyanide kushishino lweplastiki. Umzekelo, iinzame ziyenziwa ukuphuhlisa iinkqubo ezivaliweyo apho iimveliso zesodium cyanide -iziphumo ezinxulumene nemveliso yeplastiki zinokuphinda zisetyenziswe okanye ziphinde zisetyenziswe ngendlela ekhuselekileyo nezinzileyo.

isiphelo

I-sodium cyanide inendima eneenkalo ezininzi kushishino lweplastiki, ukusuka ekubeni sisithako esiphambili ekuvelisweni kwezinto zangaphambili zeplastiki eziyimfuneko ezifana ne-adiponitrile kunye ne-acrylonitrile ukuze isebenze njenge-catalyst, i-reaction aid, kunye negalelo kwimveliso yeeplastiki ezikhethekileyo kunye nokusebenza okuphezulu. Ngaphandle kwemiceli mngeni eyayanyaniswa nobutyhefu kunye neempembelelo zokusingqongileyo, iipropathi zayo ezizodwa zeekhemikhali ziyenza ibe yinto eyimfuneko kwiwebhu entsonkothileyo yeenkqubo zokwenziwa kweplastiki. Njengoko ishishini leplastiki liqhubeka nokuphuhlisa nokuphuhlisa izinto ezintsha kunye neendlela zokuvelisa, indima ye-sodium cyanide inokuvela, kodwa ukubaluleka kwayo ekwenzeni ukuveliswa koluhlu olubanzi lweemveliso zeplastiki kunokwenzeka ukuba kuqhubeke, ngaphandle kokuba ukhuseleko kunye nokukhathazeka kokusingqongileyo kuqwalaselwe ngokwaneleyo ngokuqhubela phambili kwezobuchwepheshe kunye nokuthotyelwa okungqongqo kokulawula.
