Ezicini eziningi zokukhiqizwa kwezimboni, ukuguga kwemishini bekulokhu kuyisici esibalulekile esithinta ukusebenza kahle kokukhiqiza kanye nezindleko. Ukuze kuxazululwe le nkinga, kuye kwavela izinto ezihlukahlukene ezivimbela ukugqoka, phakathi kwazo i-silicon carbide wear-resistant lining iye yaba "intandokazi entsha" emkhakheni wezimboni ngenxa yokusebenza kwayo okuhle kakhulu. Namuhla, ake singene sijule kulesi sihloko esiwumlingo.
1, Yinii-silicon carbide-resistant lining?
I-Silicon carbide (i-SiC) iyinhlanganisela eyakhiwe i-silicon ne-carbon, enesakhiwo sekristalu esiyingqayizivele nesizinzile. Amayunithi ayo esakhiwo ayisisekelo ahlanganiswe i-SiC ne-CSi tetrahedra. I-silicon carbide-resistant lining iyisendlalelo esivikelayo esenziwe ngezinto ze-silicon carbide ukuvikela ingaphakathi lemishini ekugugeni nasekudabukeni. Ingenziwa ibe yizimo ezihlukahlukene, njengezindandatho ze-ceramic, amalayini e-ceramic, njll., bese ifakwa ezindongeni zangaphakathi zezinto zokusebenza njengamapayipi, imizimba yephampu, nezisele ezivame ukuguguleka nokungqubuzana.
I-2, Izinzuzo ze-silicon carbide ulwelweno olungagugi
1. Ukuqina okuphezulu nokumelana nokugqoka okuphezulu: Ukuqina kwe-silicon carbide ceramics kuphakeme kakhulu, okwesibili kuphela kwedayimane elinzima kakhulu ngokwemvelo. Lobu bunzima obuphakeme buyenza ibe namandla ngokwedlulele ukumelana nokugqoka, ikwazi ukumelana nokuguguleka kwesivinini esikhulu kanye nokungqubuzana okuqinile kwezinto, okunweba kakhulu impilo yensizakalo yezinto zokusebenza, kuyenze ibe into efanelekile engagugi emkhakheni wezingubo ezisindayo. Uma kuqhathaniswa nezinye izinto ezijwayelekile ezikwazi ukumelana nokugqokwa, i-silicon carbide wear-resistant linening inezinzuzo ezibalulekile ekuphikisweni kokugqokwa, okunganciphisa imvamisa yokugcinwa kwemishini nokushintshwa kwamabhizinisi kanye nezindleko zokukhiqiza eziphansi.
2. Ukuminyana okuphansi nesisindo esilula: I-silicon carbide inomthamo ophansi kakhulu kunezinsimbi ezifana nensimbi. Isibonelo, ukuminyana kokusabela kwe-silicon carbide ceramics kungu-3.0g/cm ³ kuphela, kuyilapho ukuminyana kwamaceramics e-silicon carbide angenangcindezi kungu-3.14-3.0g/cm ³. Endabeni yevolumu efanayo, isisindo se-silicon carbide wear-resistant lining silula, esingasizi nje kuphela ukuthutha nokufakwa, kodwa futhi sinciphisa umthwalo wemishini wemishini, okwenza ukusebenza kwemishini kube lula, nokwenza ukufakwa kwamapayipi nezinye izinto zokusebenza kube phezulu nangaphezulu.
3. Ukumelana nokushisa okuphezulu: Inokuqina okuhle kokushisa kanye nesakhiwo sekristalu esiyingqayizivele se-silicon carbide siyivumela ukuthi imelane namazinga okushisa aphezulu, ngezinga lokushisa elishisayo elifinyelela ku-1350 ℃. Lesi sici senza i-silicon carbide-resistant lining igcine ukusebenza okuzinzile ngisho nasezindaweni zokushisa okuphezulu, ngaphandle kokuguqulwa noma ukulimala ngenxa yamazinga okushisa aphezulu, okuyenza ifaneleke izimo ezihlukahlukene zezimboni ezisezingeni eliphezulu ezifana ne-metallurgy, amandla nezinye izimboni.
4. Ukumelana nokugqwala: I-Silicon carbide inezinto zamakhemikhali ezizinzile futhi ingabonisa ukumelana nokugqwala okuhle ebusweni bamakhemikhali ahlukahlukene. Kungakhathaliseki ukuthi kuthuthwa imidiya eqinile ene-asidi neye-alkali ekukhiqizweni kwamakhemikhali noma emkhakheni wokuvikelwa kwemvelo njengokuhlanzwa kwendle, ulayini olungagugiyo lwe-silicon carbide lungavikela izinto zokusebenza ngendlela ethembekile, luvimbele okokusebenza ukuthi lungagqwali amakhemikhali, futhi lunwebe impilo yesevisi yezisetshenziswa.
5. I-conductivity ebuthakathaka kanye ne-anti-static: Izitsha zobumba ze-silicon carbide zine-conductivity ebuthakathaka, okuzenza zifanelekele izinhlelo zokusebenza ezinezidingo eziqinile zikagesi omile, njengama-workshops angaqhumi. Kulezi zindawo, ugesi omile ungase ubangele izingozi ezinkulu zokuphepha, futhi umsebenzi we-anti-static we-silicon carbide-resistant lining ungavimbela ngempumelelo ukunqwabelana kukagesi omile futhi uqinisekise ukuphepha kokukhiqiza.
6. Kulula ukwakha, ekwazi ukucubungula izingxenye ezinkulu neziyinkimbinkimbi: I-silicon carbide ingacutshungulwa kusetshenziswa izinqubo ezifana ne-reaction sintering, okuyinikeza izinzuzo ezinkulu ekubumbeni. Ngale nqubo, izitsha zobumba ezinosayizi omkhulu kanye nezitsha zobumba ezinokwakheka okuyinkimbinkimbi zingakhiqizwa. Lokhu kusho ukuthi kungakhathaliseki ukuthi ukwakheka nobukhulu bezinto zokusebenza kukhethekile kangakanani, ulwelwesi lwe-silicon carbide olungagugi lungashintshwa kahle ukuze luhlangabezane nezidingo zemishini ehlukene yezimboni.
I-silicon carbide-resistant lining ibonise inani elikhulu lohlelo lokusebenza emkhakheni wezimboni ngenxa yezinzuzo zayo eziningi. Ngokuthuthuka okuqhubekayo kanye nenqubekelaphambili yesayensi yezinto zokwakha, kukholakala ukuthi ulwelwesi lwe-silicon carbide olungagugi luzosetshenziswa emikhakheni eyengeziwe, lunikeze ukwesekwa okuqinile kokusebenza kahle nokuzinzile kokukhiqizwa kwezimboni. Uma unentshisekelo ku-silicon carbide-resistant lining, sicela ukhululeke ukuxhumana nathi nganoma yisiphi isikhathi ukuze uhlole izimfihlo eziningi mayelana nezitsha zobumba ze-silicon carbide ndawonye.
