Ingabe i-silicon nitride iyimpushana ye-ceramic?

(Ingabe i-silicon nitride iyimpushana yobumba?)

I-Silicon nitride iyimpahla ebophayo ye-athomu ezinzile futhi eqinile ekhombisa ukumelana nokugqwala okuhle kakhulu ekamelweni lokushisa. Ungqimba lwe-oxide lwakhiwe endaweni engaphezulu, luhlinzeka ngezinto ezikwazi ukumelana nokugqwala. Lesi sendlalelo sibalulekile ekumelaneni kwento ukugqwala.

Ngenxa yezinzuzo zayo, i-Silicon nitride iyinto ethandwayo yesakhiwo sezinhlelo zokusebenza eziningi ze-aerospace. Inezakhiwo ezinhle kakhulu zemishini nezinga lokushisa, okuyenza ibe indawo enhle yezinsimbi nezinye izinhlanganisela. Ingase futhi isetshenziswe ezinhlelweni ezingagugi, izinga lokushisa eliphezulu njengamaphedi we-rock arm yama-turbocharger nezinjini zegesi.

I-Silicon nitride iyisindo esingasindi ngokwedlulele, enesisindo esicishe sibe ngama-60% ngaphansi kwensimbi. Iphinde imelane kakhulu nokushaqeka kokushisa, okubalulekile ekusetshenzisweni kwezinga lokushisa eliphezulu. Inezici zemishini ezifanayo kwezinye izinto ezithuthukisiwe ze-ceramic. Izakhiwo ezishisayo nezemishini ye-Silicon nitride ziyenza ibe ukukhetha okuhle kakhulu kwezicelo ze-aerospace. Ihambisana nokuncibilika kwensimbi okungeyona insimbi.

Amabhondi e-athomu e-Silicon nitride ayivumela ukuthi ibonise izinhlobonhlobo zezakhiwo ezishisayo ezihlukile. Lesi sakhiwo sibaluleke kakhulu ezintweni zobunjiniyela. Ikala ukuthi impahla ikudlulisa kahle kangakanani ukushisa. Ngenxa yokwakheka kwamakhemikhali okuhlukile kwe-silicon kanye ne-microstructure, i-silicon nitride inokuhamba okuphansi okushisayo uma kuqhathaniswa nezinsimbi.

I-Silicon nitride iyinto ezinzile kakhulu enokwanda okuphansi kokushisa kanye nokumelana nokushaqeka okushisayo. Ivamise ukusetshenziselwa izingxenye zesakhiwo ezisezingeni eliphezulu ngenxa yamandla ayo aguquguqukayo aphezulu kanye nokuqina kokuphuka. Ngenxa yamandla ayo aphezulu futhi ilungele izicelo eziphezulu zokushisa futhi inokugqwala okuhle kakhulu nokumelana nokugqoka.

Izici eziphakeme ze-Silicon nitride mechanical and tribological ziye zayenza yaba i-tribomaterial ethandwayo. Ngenxa yalokho, i-silicon nitride iyinto ethandwayo yezicelo eziningi zezimboni. Izici zalesi sici zikwenza kube phezulu kunensimbi.

Izilinganiso ze-ATR-FTIR ne-XPS zembule izici eziningi ezithakazelisayo endaweni yezinto ezibonakalayo. Izikena ze-XPS zembula izindawo ze-zwitterionic kanye nezikhala ze-nitrogen. Lokho okutholakele kufakazelwa yi-cathodoluminescence kanye nemiphumela ye-ATR-FTIR.

Isakhiwo se-athomu kanye nezakhiwo ze-silicon nitride azishintshile. Nokho, ukwakheka kwamakhemikhali kwezakhi zayo kungashintsha ukusebenzisana kwayo kwe-electrostatic namagciwane. Ikakhulukazi, amaqembu e-silanol e-deprotonated aheha kakhulu i-electrostatic ezinsalela ze-methionine. Ngenxa yalokho, la ma-molecule ahlanganiswe ngokuqinile nobuso be-Si3N4.

Izindawo ezinamanzi zibonise i-silicon nitride inezindawo ezilwa namagciwane ngaphezu kwezakhiwo zayo zamakhemikhali. Ngokuqondile, igciwane le-ssRNA lisebenzisana nezinhlayiya ze-Si3N4 futhi liholela emazingeni aphezulu okusebenza kwegciwane. Nakuba izindlela eziqondile zalokhu kuhlangana kwamakhemikhali zihlukile kuhlobo ngalunye lwegciwane, ngokuvamile kufinyelelwa ngamaminithi. Lo mphumela uhlobene ne-hydrolysis ye-Si3N4 endaweni enamanzi.

Mayelana ne-RBOSCHCO

I-RBOSCHCO ingumhlinzeki wezinto zamakhemikhali othembekile emhlabeni wonke kanye nomkhiqizi onesipiliyoni seminyaka engaphezu kwengu-12 ekuhlinzekeni ngamakhemikhali asezingeni eliphezulu kanye nama-Nanomaterials. Le nkampani ithumela kwamanye amazwe amaningi, njenge-USA, Canada, Europe, UAE, South Africa, Tanzania, Kenya, Egypt, Nigeria, Cameroon, Uganda, Turkey, Mexico, Azerbaijan, Belgium, Cyprus, Czech Republic, Brazil, Chile, Argentina, Dubai, Japan, Korea, Vietnam, Thailand, Malaysia, Indonesia, Australia, Germany, France, Italy, Portugal njll. Njengomkhiqizi ohamba phambili wokuthuthukiswa kwe-nanotechnology, i-RBOSCHCO ibusa imakethe. Ithimba lethu lomsebenzi lochwepheshe linikeza izixazululo eziphelele zokusiza ukuthuthukisa ukusebenza kahle kwezimboni ezahlukene, ukudala inani, kanye nokubhekana kalula nezinselele ezahlukahlukene.
