Umkhiqizi we-refractory ukushisa okuphezulu kwe-sandblasting e-castable white corundum sand powder fine

Izinto eziphikisayo

umqondo:
Ikilasi lezinto ezingaphili ezingezona ezensimbi ezine-refractoriness engekho ngaphansi kuka-1580°C.I-Refractoriness ibhekisela kumazinga okushisa e-Celsius lapho isampula yekhoni ephikisayo imelana nesenzo sokushisa okuphezulu ngaphandle kokuthambisa nokuncibilika ngaphansi kwesimo sokungathwali.Kodwa-ke, incazelo ye-refractoriness kuphela ayikwazi ukuchaza ngokugcwele izinto eziphikisayo, futhi i-1580 ° C ayiphelele.Manje sekuchazwa ngokuthi zonke izinto ezinezici zazo zomzimba namakhemikhali ezivumela ukuthi zisetshenziswe endaweni yokushisa ephezulu zibizwa ngokuthi izinto eziphikisayo.Izinto eziphikisayo zisetshenziswa kabanzi kwezensimbi, imboni yamakhemikhali, i-petroleum, ukukhiqizwa kwemishini, i-silicate, amandla kanye neminye imikhakha yezimboni.Zinkulu embonini ye-metallurgical, zibalelwa ku-50% kuya ku-60% wesamba somkhiqizo.

umphumela:
Izinto eziphikisayo zisetshenziswa emikhakheni eyahlukene yomnotho wezwe njengensimbi, izinsimbi ezingenayo insimbi, ingilazi, usimende, izitsha zobumba, amakhemikhali e-petrochemicals, imishini, ama-boilers, imboni yokukhanya, amandla kagesi, imboni yezempi, njll., futhi kuyizinto ezibalulekile eziyisisekelo ukuqinisekisa ukusebenza kokukhiqiza kanye nokuthuthukiswa kwezobuchwepheshe kwezimboni ezingenhla.Idlala indima ebalulekile nengenakushintshwa ekuthuthukisweni kokukhiqizwa kwezimboni ezisezingeni eliphezulu.
Kusukela ngo-2001, iqhutshwa ukuthuthuka okusheshayo kwezimboni ezisezingeni eliphezulu ezifana nensimbi nensimbi, izinsimbi ezingenayo insimbi, amakhemikhali kaphethiloli, nezinto zokwakha, imboni ephikisayo igcine umfutho omuhle wokukhula futhi isibe ngumkhiqizi omkhulu kanye nomthengisi omkhulu wezinto eziphikisayo endaweni. umhlaba.Ngo-2011, ukukhiqizwa kwe-refractory yaseChina kwabalelwa cishe ku-65% wengqikithi yomhlaba, futhi ukukhiqizwa kwayo nomthamo wokuthengisa kubekwe phambili kancane kancane emhlabeni.
Ukuthuthukiswa kwemboni ephikisayo kuhlobene eduze nokugcinwa kwezimbiwa zasekhaya.I-Bauxite, i-magnesite ne-graphite yizinto ezintathu ezinkulu eziphikisayo.I-China ingelinye lamazwe amathathu ahweba kakhulu emhlabeni athumela i-bauxite, inqolobane enkulu kunazo zonke emhlabeni ye-magnesite, kanye nomhwebi omkhulu we-graphite.Izinsiza ezicebile ziye zasekela izinto zokuphikisa zaseShayina iminyaka eyishumi yentuthuko esheshayo.
Ngenkathi “Yohlelo Lweminyaka Eyishumi Nambili Yeminyaka Emihlanu”, i-China isheshisa ukuqedwa komthamo wokukhiqiza odle isikhathi esiningi nosebenzisa amandla amaningi.Imboni izogxila ekuthuthukisweni nasekugqugquzeleni izindawo ezintsha zokonga ugesi, ukuthuthukiswa kobuchwepheshe obuphelele bokonga ugesi, ukuphathwa kukagesi, ukulawulwa kokukhipha intuthu “yemfucumfucu emithathu” kanye nokusetshenziswa kwezinsiza “Zokumosha izinto ezintathu” Zokugaywa kabusha, njll. Sizibophezele ekutheni ukugaywa kabusha kwezinsiza kanye nokusetshenziswa kabusha kwezinto eziphikisayo ngemva kokusetshenziswa, ukunciphisa ukukhishwa kwemfucuza eqinile, ukuthuthukisa ukusetshenziswa okuphelele kwezinsiza, futhi kukhuthaze ngokuphelele ukongiwa kwamandla kanye nokunciphisa ukungcola.
"Inqubomgomo Yokuthuthukiswa Kwemboni Ephikisayo" iveza ukuthi ukusetshenziswa kweyunithi yezinto eziphikisayo embonini yensimbi yaseChina cishe amakhilogremu angama-25 ngethani lensimbi, futhi izokwehla ngaphansi kwamakhilogremu angu-15 ngo-2020. Ngo-2020, imikhiqizo yaseShayina e-refractory izophila isikhathi eside. , yonga amandla kakhudlwana, ayingcolisi, futhi iyasebenza.Imikhiqizo izohlangabezana nezidingo zokuthuthukiswa komnotho kazwelonke njengensimbi, izinto zokwakha, amakhemikhali, nezimboni ezisafufusa, futhi izokwandisa okuqukethwe kwezobuchwepheshe kwemikhiqizo ethunyelwa ngaphandle.

Izinto eziphikisayo zinezinhlobonhlobo eziningi kanye nokusetshenziswa okuhlukile.Kuyadingeka ukuhlukanisa ngokwesayensi izinto eziphikisayo ukuze kube lula ucwaningo lwesayensi, ukukhetha okunengqondo nokuphatha.Ziningi izindlela zokuhlukanisa izinto eziphikisayo, okuhlanganisa ukuhlukaniswa kwezibaluli zamakhemikhali, ukuhlukaniswa kwamakhemikhali amaminerali, ukuhlukaniswa kwenqubo yokukhiqiza, kanye nokuhlukaniswa kwe-material morphology.

Ukuhlukaniswa:
1.Ngokwezinga le-refractoriness:
Izinto ezijwayelekile eziphikisayo: 1580 ℃ ~ 1770 ℃, izinto eziphikisayo ezithuthukisiwe: 1770 ℃ ~ 2000 ℃, izinto eziphikisayo zebanga elikhethekile: > 2000 ℃
2. Izinto eziphikisayo zingahlukaniswa zibe:
Imikhiqizo eshisiwe, imikhiqizo engashisiwe, ama-refractories angakhiwe
3. Kuhlukaniswa ngezakhiwo zamakhemikhali:
I-Acid refractory, i-neutral refractory, i-alkaline refractory
4. Ukuhlukaniswa ngokwezigaba zamaminerali
Le ndlela yokuhlukanisa ingabonisa ngokuqondile ukwakheka okuyisisekelo nezici zezinto ezihlukahlukene zokuphikisa.Kuyindlela evamile yokuhlukanisa ekukhiqizeni, ekusetshenzisweni, nasocwaningweni lwesayensi, futhi inokubaluleka okuqinile kokusebenza okusebenzayo.
I-silica (silica), i-aluminium silicate, i-corundum, i-magnesia, i-magnesia calcium, i-aluminium magnesia, i-silicon ye-magnesia, i-carbon composite refractories, i-zirconium refractories, i-refractories ekhethekile.
6. Ukuhlelwa kwezinto eziphikisayo ezingakabunjwa (ezihlukaniswa ngendlela yokusetshenziswa)
Ama-castable, ama-spray coatings, izinto zokunqanda, amapulasitiki, izinto zokubamba, izinto zokuqagela, izinto zokugcoba, izinto ezomile ezidlidlizayo, izinto ezisakazwayo ezigeleza ngokwazo, ama-slurries aphikisayo.
Ama-refractories angathathi hlangothi ikakhulukazi akhiwa i-alumina, i-chromium oxide noma ikhabhoni.Umkhiqizo we-corundum oqukethe ngaphezu kwe-95% i-alumina uyinto esezingeni eliphezulu ephikisayo enezinhlobonhlobo zokusetshenziswa.
I-Chiping Wanyu Industry and Trade Co., Ltd., eyasungulwa ngo-2010, igxile ekukhiqizweni kwemikhiqizo engagugi futhi eqinile: isihlabathi sengxenye ye-corundum emhlophe, impushana ecolekile, kanye nemikhiqizo yochungechunge lwesihlabathi esiyimbudumbudu.
Ukucaciswa kochungechunge okumelana nokugqokwa: 8-5#, 5-3#, 3-1#, 3-6#, 1-0#, 100-0#, 200-0#, 325-0#
Imininingwane yesihlabathi esiyimbudumbudu: 20#, 24#, 36#, 40#, 46#, 54#, 60#, 80#, 100#, 150#, 180#, 200#, 220#, 240#,
