Emkhakheni wokukhiqiza izimboni, ukukhetha izinto zobumba ezifanele kufana nokuthola abalingani abathembekile - kudinga ukumelana novivinyo lwesikhathi, ukumelana nezimo ezimbi kakhulu, nokuqhubeka nokwengeza inani ekusebenzeni kahle kokukhiqiza. Ungakhetha kanjani ngokuhlakanipha lapho ubhekene nohlu olumangalisayo lwemikhiqizo yobumba yezimboni? Lesi sihloko sizoveza izinto ezibalulekile zokukhetha izinto zobungcweti kanye nokugxila ekuhlaziyeni izinzuzo eziyingqayizivele zeizitsha zobumba ze-silicon carbide, eyaziwa ngokuthi “izikhali zezimboni”.
1, Imithetho Emithathu Yegolide Yokukhetha Izitsha Zobumba Zezimboni
1. Izinga lokufanisa ukusebenza: Okokuqala, kubalulekile ukucacisa izidingo ezibalulekile zesimo sokusetshenziswa. Ingabe yindawo yokushisa ephezulu kakhulu? I-medium enamandla okugqwala? Noma ukungqubuzana kwemishini okuvame kakhulu? Njengokukhetha imishini yokukhuphuka izintaba ukuze kuhlukaniswe phakathi kweqhwa nogwadule, izimo zokusebenza ezahlukene zidinga izinto zobumba ezinezimpawu ezifanayo.
2. Umjikelezo wokuphila kwenkonzo: Inani lezinto zobumba ezisezingeni eliphezulu libonakala ekusetshenzisweni kwesikhathi eside. Akufanele siqaphele nje izindleko zokuthenga zokuqala, kodwa futhi sibale izindleko ezingacacile ezibangelwa ukugcinwa kanye nokushintshwa kaningi. Izinto zobumba ezisezingeni eliphezulu zezimboni kufanele zithembeke njengezinto "ezingadingi ukulungiswa".
3. Amandla okusekela ubuchwepheshe: Abaphakeli abahle kakhulu abakwazi nje ukuhlinzeka ngemikhiqizo ejwayelekile, kodwa futhi bathuthukise amafomula kanye nezakhiwo zokuklama ngokusekelwe ezimweni ezithile zokusebenza, okuvame ukunquma ukusebenza kokugcina kwezinto ezisetshenziswayo.
2, Izinzuzo ezine ezinkulu zokusebenza kwe-silicon carbide ceramics
Njengezinto ezibonakalayo zezinto zobumba zezimboni zanamuhla, izinto zobumba ze-silicon carbide seziba ukukhetha okuthandwayo kwamabhizinisi amaningi. Inhlanganisela yayo yokusebenza eyingqayizivele ingabizwa ngokuthi “iqhawe eliyi-hexagonal” lezinto zobumba zezimboni:
1. Izembatho zempi eziqinile kakhulu: Isakhiwo sekristalu sisinika ubulukhuni obulandela idayimane kuphela, obungandisa ngempumelelo impilo yenkonzo yemishini ezimweni ezifana nezinhlelo zokudlulisa ezicindezelekile njalo kanye nama-bearings anembile.
2. Isivikelo samakhemikhali: Simelana kahle kakhulu nama-asidi aqinile, izinsimbi ezincibilikisiwe, njll., futhi sifaneleka kakhulu ezindaweni ezigqwalisayo njengemikhumbi yokusabela kwamakhemikhali kanye nezinhlelo zokususa i-sulfurization zezimboni, sigwema ukungcola okuphakathi okubangelwa ukulahleka kwezinto.
3. I-Thermal Stability Guardian: Ingagcina ukuqina kwesakhiwo ngisho noma amazinga okushisa aphezulu angu-1350 ℃, nge-coefficient yokwandisa ukushisa engu-1/4 kuphela yensimbi, okwenza kube ukukhetha okuhle kwama-oven ashisa kakhulu kanye nezinhlelo zokuvikela ukushisa zasemkhathini.
4. Isazi esilula: Njengoba sinobukhulu obuyingxenye eyodwa kwezintathu kuphela bensimbi, singanikeza amandla omshini afanayo noma aphezulu, futhi sinezinzuzo ezisobala emishinini ezenzakalelayo kanye nasezindaweni ezintsha zamandla ezidinga ukunciphisa isisindo kanye nokuthuthukiswa kokusebenza kahle.
3, Iziphakamiso zokukhetha izinto ezithuthukisiwe
Ngaphezu kwemingcele eyisisekelo, kunconywa ukugxila emininingwaneni yenqubo efana nokufana kwesakhiwo sezinto ezincane kanye nokushelela komphezulu. Lezi 'zimfanelo ezingabonakali' zivame ukunquma ukusebenza kwezinto ezimweni ezibucayi.
Ukukhetha izinto zobumba zezimboni empeleni ukukhetha "umqaphi" womugqa wokukhiqiza. Izinto zobumba ze-silicon carbide, ezinezinhlanganisela zazo ezihlukile zezakhiwo, zichaza kabusha ukuqonda kokuthembeka ekukhiqizeni kwezimboni. Uma ubhekene nezinselele zokusebenza eziyinkimbinkimbi, vumela lo mdlali oguquguqukayo embonini yezinto zokwakha akhe umugqa wokuzivikela oqinile.
Sesineminyaka engaphezu kweyishumi sihileleke kakhulu emkhakheni we-silicon carbide ceramics, sigxile ekuhlinzekeni ngezixazululo zezinto ezenziwe ngokwezifiso kumakhasimende. VakashelaShandong Zhongpengukuthola idatha eningi elinganisiwe ngezimo zohlelo lokusebenza, noma xhumana nethimba lethu lobunjiniyela ukuze wenze ngezifiso izixazululo zokukhetha izinto zakho.
