Izakhiwo kanye nokusetshenziswa okuyinhloko kwe-react-sintered silicon carbide

Izakhiwo ze-Reaction-sintered silicon carbide kanye nokusetshenziswa okuyinhloko? I-silicon carbide nayo ingabizwa ngokuthi i-carborundum noma isihlabathi esingashisi umlilo, iyinhlanganisela ye-inorganic, ehlukaniswe yaba i-silicon carbide eluhlaza kanye ne-silicon carbide emibili. Uyazazi izakhiwo kanye nokusetshenziswa okuyinhloko kwe-silicon carbide? Namuhla, sizokwethula izakhiwo kanye nokusetshenziswa okuyinhloko kwe-silicon carbide.

I-reactive sintering silicon carbide ukusetshenziswa kwesihlabathi se-quartz, i-coke ye-petroleum calcined (noma i-coking yamalahle), i-wood slag (ukukhiqizwa kwe-silicon carbide eluhlaza idinga ukwengeza usawoti wokudla) nezinye izinto zokusetshenziswa, ngokusebenzisa isithando somlilo sikagesi esiqhubekayo sokuncibilikisa izinga lokushisa eliphezulu.

Izici ze-react-sintered silicone carbide:

1. I-thermal conductivity kanye ne-thermal yokwandisa i-coefficient ye-silicon carbide. Njengohlobo lwezinto eziphikisayo, isitini se-carbonized sinokumelana okuhle kakhulu nokushaqeka. Lokhu kubonakala ngokuyinhloko ekuqhubeni kwayo okushisayo okuqinile (i-coefficient yokudlulisa ukushisa) kanye ne-coefficient ephansi kakhulu yokwandisa ukushisa.

2, ukuqhutshwa kwe-silicon carbide. I-Silicon carbide iyimpahla ye-semiconductor, ukuqhutshwa kwayo kuyahlukahluka ngohlobo kanye nenani lokungcola okwethulwa ku-crystallization, futhi ukumelana kuphakathi kwe-10-2-1012Ω · cm. Phakathi kwazo, i-aluminium, i-nitrogen ne-boron inethonya elikhulu ekuziphatheni kwe-silicon carbide, futhi ukuqhutshwa kwe-silicon carbide nge-aluminium eyengeziwe kukhuphuka kakhulu.

3. Ukumelana ne-silicon carbide. Ukumelana kwe-silicon carbide kuyashintsha ngokushintsha kwezinga lokushisa, kodwa ngaphakathi kwebanga elithile lokushisa kanye nezici zokushisa ze-resistor yensimbi ziyahlehliswa. Ubudlelwano phakathi kokumelana nezinga lokushisa kwe-silicon carbide bunzima kakhulu. I-conductivity ye-react-sintered silicon carbide ikhuphuka ngezinga lokushisa likhuphukela enanini elithile, futhi ukuqhutshwa kwe-conductivity kuyehla lapho izinga lokushisa likhuphuka futhi.

Ukusetshenziswa kwe-silicon carbide:

I-1, izinto ezikwazi ukumelana nokugqoka - ikakhulukazi ezisetshenziselwa ukwenza isondo lesihlabathi, i-sandpaper yokugaya, i-whetstone, isondo lokugaya, i-grinding paste kanye nemikhiqizo ye-photovoltaic kumaseli e-photovoltaic, amaseli e-photovoltaic kanye nezingxenye zokugaya phezulu, ukugaya nokupholisha.

I-2, izinto eziphikisayo ezisezingeni eliphezulu - zingasetshenziswa njenge-deoxidizer yemboni ye-metallurgical kanye nezinto ezimelana nokugqwala, ukwenza izinto eziqhubekayo zokushisa eziphakeme zokushisa ezifakelwe ngaphambili, izingxenye ezingaguquki, njll.

I-3, i-ceramics esebenzayo - ayigcini nje ukunciphisa umthamo womlilo, kodwa futhi ithuthukise ikhwalithi yemikhiqizo yokushisa yezimboni, ukunciphisa isikhathi somjikelezo, iyinto efanelekile engaqondile ye-ceramic glaze sintering, izinga lokushisa eliphezulu eliqhubekayo le-non-oxide ceramics, elibonisa i-porcelain e-sintered.

4, izinsimbi ezingavamile - amabhizinisi ensimbi nensimbi, inkambu ye-metallurgical concentrator field, anesicelo esithile.

I-5, enye - isetshenziselwa ukwenza i-far-infrared radiation coating noma i-silicon carbide plate dry-infrared radiation dryer.

I-silicon carbide ngenxa yezinto ezibushelelezi zamakhemikhali e-organic, i-coefficient yokudlulisa ukushisa okuphezulu, i-coefficient encane yokwandisa umugqa, ukumelana okuhle kokugqokwa, ngaphezu kwezinto ezikwazi ukumelana nokugqoka, kukhona okunye ukusetshenziswa okuyinhloko, okufana nalokhu: ngenqubo entsha ye-silicon carbide powder glue i-centrifugal impeller noma i-cylinder body cavity, ingathuthukisa ukumelana nokugqoka futhi ikhulise impilo yesevisi izikhathi ezi-1 kuya kwezi-2; Isetshenziselwa ukwenza i-high grade refractory material, izinga lokushisa eliphezulu ukumelana nokushaqeka, usayizi omncane, isisindo esilula namandla aphezulu, ukuvikelwa kwemvelo kanye nomphumela wokonga amandla kusobala. I-silicon carbide yezinga eliphansi (equkethe cishe u-85% we-SiC) iyi-ejenti enhle ye-deoxidizing, engase isetshenziselwe ukusheshisa izinga lokwenziwa kwensimbi, futhi ilungele ukuphatha ukwakheka kanye nokwenza ngcono ikhwalithi yensimbi. Ngaphezu kwalokho, i-silicon carbide isetshenziselwa ukwenza izinto eziningi zokushisa zikagesi i-silicon molybdenum rod.
