Ezimbonini ezishisa kakhulu njenge-metallurgy, i-ceramics, kanye nobunjiniyela bamakhemikhali, ukuzinza nokuqina kwemishini kuthinta ngqo ukusebenza kahle kokukhiqiza kanye nezindleko. Njengengxenye "yomphimbo" yesistimu yokushisa, i-burner sleeve ibilokhu ibhekene nezinselele ezifana nomphumela womlilo, ukugqwala kokushisa okuphezulu, kanye nokushintsha kwezinga lokushisa okungazelelwe. Inkinga yokuguquguquka kanye nokuphila isikhathi esifushane kwe-metal burner sleeves yendabuko ishintshwa buthule uhlobo olusha lwezinto:imikhono yesishisi se-silicon carbide (SiC)seziba yintandokazi entsha ezimweni zokushisa okuphezulu kwezimboni ngenxa yokusebenza kwazo “okuqinile”.
1, i-Silicon carbide: Yazalelwa amazinga okushisa aphezulu
I-silicon carbide ayiyona umkhiqizo osafufusa elabhorethri. Ngasekupheleni kwekhulu le-19, abantu bathola le nhlanganisela eyakhiwe yi-silicon ne-carbon. Isakhiwo sayo sekristalu siyinika 'amandla amakhulu' amathathu amakhulu:
1. Ukumelana nokushisa okuphezulu: okukwazi ukugcina amandla ku-1350 ℃, okudlula kakhulu izinga lokuncibilika kwezinsimbi ezivamile;
2. Ukumelana nokuguguleka: Njengoba ibhekene nezimo zokuguguleka okuphezulu, isikhathi sayo sokuphila siphindwe kaningana kunesezinto ezivamile;
3. Ukumelana nokugqwala: Inamandla okumelana nezimo ezi-acidic kanye ne-alkaline kanye nokugqwala kwensimbi encibilikisiwe.
Lezi zici zenza i-silicon carbide ibe ukukhetha okuhle kwezinto zokusika, ikakhulukazi ezifanele imishini yokushisa edinga ukuchayeka isikhathi eside emalangabini avulekile.
2. Izinzuzo ezintathu ezinkulu zesikhafu sesishisi se-silicon carbide
Uma kuqhathaniswa nemikhono yensimbi yendabuko noma ye-ceramic ephikisayo, izinzuzo zenguqulo ye-silicon carbide zibonakala ngokucacile:
1. Ukuphinda kabili isikhathi sokuphila
Isivikelo sesishisi sensimbi sithambekele ekushiseni nasekuthambiseni emazingeni okushisa aphezulu, kuyilapho ukuqina kwe-silicon carbide kwandisa impilo yayo yenkonzo izikhathi ezi-3-5, kunciphisa imvamisa yokuvala nokufaka esikhundleni.
2. Ukonga amandla kanye nokuthuthukiswa kokusebenza kahle
Ukushisa kwe-silicon carbide kuphindwe kaningana kunokwezinto zobumba ezivamile, ezingadlulisa ukushisa ngokushesha, zithuthukise ukusebenza kahle kokushisa kukaphethiloli, futhi zinciphise ukusetshenziswa kwamandla.
3. Ukulungiswa okulula
Imelana nokuguguleka, imelana nokugqwala, futhi imelana nokushisa okuphezulu, okudinga ukulungiswa okulula kwansuku zonke, okunciphisa kakhulu izindleko zokulungisa.
3, Yiziphi izimboni ezikudinga kakhulu?
1. Isitofu se-ceramic: Sifanelekela izindawo zokushisa ezicwebezelayo ezingaphezu kuka-1300 ℃
2. Ukwelashwa kokushisa kwensimbi: ukumelana nokuqhekeka kwensimbi encibilikisiwe kanye nokuguguleka kwe-slag
3. Ukushiswa kukadoti: ukumelana nokugqwala okunamandla kwegesi equkethe i-chlorine
4. Isithando sokuncibilikisa ingilazi: sifanele ukusebenza isikhathi eside ngaphansi kwesimo sezulu se-alkaline
4, amathiphu okusebenzisa
Nakuba ukusebenza kahle kwesikhafu sesishisi se-silicon carbide kuqinile, ukusetshenziswa okufanele kusabalulekile:
1. Gwema ukushayisana kwemishini ngesikhathi sokufakwa ukuze uvimbele imifantu efihliwe
2. Kunconywa ukwandisa izinga lokushisa isinyathelo ngesinyathelo ngesikhathi sokuqala kokubanda
3. Susa njalo ungqimba lokubilisa olungaphezulu bese ugcina umlomo ungaphazanyiswa
Njengomhlinzeki wesevisi yezobuchwepheshe ohileleke kakhulu emkhakheni wezinto eziphikisayo zezimboni, sihlala sinaka ukusetshenziswa kanye nokuguqulwa kobuchwepheshe bezinto ezisezingeni eliphezulu. Ukukhuthazwa kwemikhono yokushisa ye-silicon carbide akuyona nje ukuthuthukiswa kwezinto, kodwa futhi kuyimpendulo yesidingo sokukhiqiza kwezimboni "okusebenzayo kakhudlwana, okonga amandla, nokuthembekile". Esikhathini esizayo, sizoqhubeka nokwenza ngcono izinqubo zomkhiqizo futhi sinike amandla amabhizinisi amaningi ukusebenzisa izixazululo ezimelana nokushisa okuphezulu "ezihlala isikhathi eside futhi ezingabizi kakhulu".
Ithimba lochwepheshe laseShandong Zhongpeng lingakunikeza iziphakamiso zokukhetha ezenziwe ngokwezifiso kanye nokusekelwa kobuchwepheshe. Siyakwamukela ku-sivakasheleukuthola izixazululo ezikhethekile.
