Iqhaza Le-Sodium Cyanide Embonini Yepulasitiki

Isingeniso

Sodium i-cyanide (I-NaCN), inhlanganisela ye-inorganic, inohlu olubanzi lwezinhlelo zokusebenza kuzo zonke izimboni ezahlukahlukene naphezu kwemvelo yayo enobuthi obukhulu. Kwe Imboni yepulasitiki, I-sodium cyanide idlala izindima ezibalulekile eziningana ezinqubweni ezehlukene, okunomthelela ekukhiqizeni izinhlobonhlobo zezinto zepulasitiki nemikhiqizo.

Ukukhiqizwa Kwezimbangi ZePlastiki

I-Adiponitrile Synthesis Yokukhiqiza Inayiloni

Enye yezinhlelo zokusebenza ezibalulekile ze I-Sodium Cyanide embonini yepulasitiki isekukhiqizweni kwe I-Adiponitrile, okuyisandulela esiyinhloko INylon 6.6 - ifayibha yokwenziwa esetshenziswa kabanzi emkhakheni wepulasitiki. Inqubo ihilela ukukhiqizwa kwe-hydrogen cyanide kusuka i-sodium cyanide. I-Hydrogen cyanide bese ibamba iqhaza ochungechungeni lokusabela ukwenza i-adiponitrile. Ngokukhula kwesidingo senayiloni embonini yezindwangu kanye nomkhakha wokukhiqiza wemikhiqizo ehlukahlukene efana nezingubo, okhaphethi, nezingxenye zezimoto, isidingo se-adiponitrile, futhi ngenxa yalokho, i-sodium cyanide, siyakhula. Isibonelo, ekukhiqizeni amabhande ezihlalo zezimoto ezisezingeni eliphezulu, imicu inayiloni engu-6.6, etholakala ku-adiponitrile ekhiqizwa kusetshenziswa izinqubo ezisekelwe ku-sodium cyanide, inikeza amandla adingekayo nokuqina.

Ukukhiqizwa kwe-Acrylonitrile ye-Polyacrylonitrile (PAN)

I-sodium cyanide nayo ihilelekile ekukhiqizeni i-acrylonitrile, esetshenziselwa ukukhiqiza i-polyacrylonitrile (PAN). I-PAN iyi-polymer ebalulekile esebenza ezindaweni ezinjengemicu yokwenziwa embonini yendwangu nanjengesandulela semicu yekhabhoni. Ekukhiqizeni i-acrylonitrile, amakhemikhali atholakala kwi-sodium cyanide asabela nezinye izinhlanganisela ukuze akhe i-acrylonitrile monomer. Lawa ma-monomers abe esenziwe i-polymerized ukuze enze i-polyacrylonitrile. Amafayibha ekhabhoni enziwe nge-PAN anamandla amakhulu - kuya - kwesisindo futhi asetshenziswa ezingxenyeni ze-aerospace, imishini yezemidlalo esebenza kahle kakhulu, nezinto eziyinhlanganisela eziphambili. Ukusetshenziswa kwe-sodium cyanide ochungechungeni lokukhiqiza lwe-acrylonitrile kanye nemikhiqizo ye-PAN elandelayo kugqamisa ukubaluleka kwayo ekuvumela ukukhiqizwa kwezinto ezisekelwe kupulasitiki ezisezingeni eliphezulu nezisezingeni eliphezulu.

Njengosizo Lokusabela

I-Catalysis ku-Specific Polymerization Reactions

Kwezinye izimo ze-polymerization embonini yepulasitiki, i-sodium cyanide ingasebenza njenge-catalyst noma insiza yokusabela. Isibonelo, kwezinye izinqubo ze-condensation polymerization lapho amaqembu athile asebenzayo adinga ukusabela ukuze akhe amaketanga e-polymer, i-sodium cyanide ingenza kube lula ukusabela ngokukhuthaza ukwenziwa kusebenze kwama-reactants. Kungasiza ekwephuleni nasekwakheni amabhondi amakhemikhali ngendlela esheshisa inqubo yokwenza i-polymerization, okuholela ekukhiqizweni okuphumelelayo kwamapulasitiki. Lokhu kuwusizo ikakhulukazi ekukhiqizeni amapulasitiki akhethekile lapho kudingeka khona ukulawula okunembile kwezinga lokusabela kanye nesakhiwo se-polymer. Ngokusebenzisa i-sodium cyanide njengosizo lokuphendula, abakhiqizi bangakwazi ukufeza isisindo esidingekayo se-molecular and polymer architecture ngokuphumelelayo.

Ukwenza Ukuguqulwa Kwamakhemikhali Kupulasitiki

I-sodium cyanide ingasetshenziselwa ukwethula amaqembu athile amakhemikhali noma ukusebenza kwawo kuma-polymer epulasitiki. Ngokuphendula kwamakhemikhali okuklanywe ngokucophelela, iqembu le-cyanide elisuka ku-sodium cyanide lingafakwa kumgogodla we-polymer noma amaketanga aseceleni. Lokhu kuguqulwa kungashintsha izici zepulasitiki, ezinjengokuthuthukisa ukunyibilika kwayo, ukusebenza kabusha, noma izici zokunamathela. Isibonelo, ekukhiqizeni izinto ezinamathelayo ezithile ezisekelwe kuma-polymers epulasitiki, ukwethulwa kwamaqembu atholwe yi-cyanide kungathuthukisa ikhono le-adhesive lokunamathela kuma-substrates ahlukene, kukwenze kusebenze kangcono ekusetshenzisweni okufana nokuhlanganisa izingxenye zepulasitiki ezimbonini zikagesi noma zezimoto.

Ekukhiqizeni Ipulasitiki Okukhethekile

Ukukhiqizwa kwe-Sodium Ferrocyanide - Ipulasitiki Ezinzile

I-sodium cyanide isetshenziswa ekukhiqizeni i-sodium ferrocyanide, esebenza njenge-stabilizer kumapulasitiki. Amapulastiki ayingxenye ebalulekile yemikhiqizo eminingi yezimboni neyabathengi, futhi ukuzinza kwawo kubalulekile ekugcineni ikhwalithi yomkhiqizo neminyaka yokuphila. I-sodium ferrocyanide isiza ekuvimbeleni ukuwohloka kwamapulasitiki ngenxa yezinto ezahlukahlukene ezinjengokushisa, ukukhanya, nokuchayeka kwamakhemikhali. Ezinhlelweni lapho amapulasitiki echayeke endaweni enzima, njengasefenisha yangaphandle, amapayipi okuthutha amakhemikhali, noma izindlu zemishini kagesi, ukusetshenziswa kwe-sodium ferrocyanide - amapulasitiki azinzile, anikwe amandla ngokusetshenziswa kwe-sodium cyanide ekukhiqizeni kwawo, kuqinisekisa ukuthi imikhiqizo yepulasitiki igcina ubuqotho besakhiwo nokusebenza kwayo ngokuhamba kwesikhathi.

Iqhaza Ekukhiqizeni Ipulasitiki Yobunjiniyela Esebenza Kakhulu

Ekukhiqizeni amapulasitiki wobunjiniyela asebenza kahle kakhulu, aklanyelwe ukumelana nezimo ezimbi kakhulu ezifana namazinga okushisa aphezulu, izingcindezi eziphezulu, nezindawo ezigqwalile, i-sodium cyanide ingadlala indima engaqondile kodwa ebalulekile. Njengoba kushiwo ngaphambili, kunomthelela ekukhiqizeni ama-monomer abalulekile kanye nezinsiza zokusabela ezisetshenziswa ekuhlanganiseni lawa mapulasitiki athuthukile. Isibonelo, ekukhiqizeni i-polyetheretherketone (PEEK), esetshenziselwa i-aerospace, izimoto, kanye nezicelo zezokwelapha ngenxa yezakhiwo zayo ezinhle kakhulu zokumelana nemishini namakhemikhali, inqubo yokuhlanganiswa eyinkimbinkimbi ingase ihlanganise izinyathelo ezithembele kumakhemikhali atholakala ku-sodium cyanide. Nakuba ukusetshenziswa okuqondile kwe-sodium cyanide ekukhiqizweni kwe-PEEK kungase kungabonakali, lonke uchungechunge lokunikezwa kwamakhemikhali okuholela ekukhiqizweni kwama-PEEK monomers kanye nokwenza kahle kokusabela kwe-polymerization kungalandelelwa emuva ekusetshenzisweni kwe-sodium cyanide ezigabeni zangaphambili zokukhiqiza amakhemikhali.

Ukucatshangelwa Kwemvelo Nokuphepha

Nakuba i-sodium cyanide ibalulekile embonini yepulasitiki, ubuthi bayo obudlulele bufuna izinyathelo eziqinile zokuphepha kuzo zonke izigaba zokusetshenziswa kwayo, kusukela ekukhiqizeni kuye ekulahleni. Ezindaweni zokukhiqiza amapulasitiki, izinqubo ezifanele zokuphatha, njengokusetshenziswa kwezinto zokuzivikela, izindawo zokusebenza ezinomoya omuhle, nokugcinwa okuphephile kwe-sodium cyanide, kubalulekile ukuvimbela noma yikuphi ukuchayeka ngengozi kubasebenzi. Ukwengeza, ukukhathazeka kwemvelo mayelana nokulahlwa kwemfucuza equkethe i-sodium cyanide noma imikhiqizo yayo kubalulekile. Kunemithetho eqinile ekhona yokuqinisekisa ukuthi noma iyiphi imfucuza iphathwa ngendlela ukuze kuvinjelwe ukungcoliswa komhlabathi, amanzi nomoya. Izinyathelo zokugaywa kabusha kanye nokunciphisa imfucuza nazo ziyahlolwa ukuze kuncishiswe umthelela wemvelo ohambisana nokusetshenziswa kwe-sodium cyanide embonini yepulasitiki. Isibonelo, kwenziwa imizamo yokuthuthukisa amasistimu eluphu avaliwe lapho imikhiqizo ye-sodium cyanide - ukusabela okuhlobene ekukhiqizeni kwepulasitiki kungagaywa kabusha noma kusetshenziswe kabusha ngendlela ephephile neqhubekayo.

Isiphetho

I-sodium cyanide inendima ehlukahlukene embonini yepulasitiki, isuka ekubeni yisithako esibalulekile ekukhiqizeni izanduleli zepulasitiki ezibalulekile njenge-adiponitrile ne-acrylonitrile ukuze isebenze njenge-catalyst, usizo lokusabela, nokuba negalelo ekukhiqizeni amapulasitiki akhethekile futhi asebenza kakhulu. Naphezu kwezinselelo ezihambisana nobuthi kanye nomthelela wemvelo, izakhiwo zayo zamakhemikhali eziyingqayizivele ziyenza ibe yinhlanganisela ebaluleke kakhulu kuwebhu eyinkimbinkimbi yezinqubo zokukhiqiza amapulasitiki. Njengoba imboni yepulasitiki iqhubeka nokusungula nokuthuthukisa izinto ezintsha nezindlela zokukhiqiza, indima ye-sodium cyanide ingase iguquke, kodwa ukubaluleka kwayo ekwenzeni ukukhiqizwa kwemikhiqizo eminingi yepulasitiki iqhubeke, inqobo nje uma ukukhathazeka kwezokuphepha kanye nemvelo kubhekwana nayo ngokwanele ngentuthuko yezobuchwepheshe kanye nokuhambisana nemithetho eqinile.
