Indlela yokuthuthukisa ukumelana nezinga lokushisa kwe ukuchithwa kwesithando somlilo ulayini? Ngemva kokuyifunda, ngiye ngazuza kakhulu!

Ukusebenza kokushisa okuphezulu kolwelwesi lwesithando somlilo ikakhulukazi kuncike ezintweni ezibonakalayo, zamakhemikhali kanye nokwakheka kwamaminerali wezinto eziphikisayo ezisetshenziswayo. Ngaphansi kwesisekelo sokukhetha izinto ezingavuthiwe neziyisizayo, inqubo ye-sintering iwukhiye wokuthola i-microstructure enhle yolayini lwesithando somlilo ukuze unikeze ukudlala okugcwele ekumelaneni kwayo nezinga lokushisa eliphezulu. Inqubo. Izinga lokuminyana kolayini be-sintering lihlobene nokwakheka kwamakhemikhali, isilinganiso sosayizi wezinhlayiyana, inqubo ye-sintering kanye nezinga lokushisa le-sintering lezinto eziphikisayo.

Inqubo yokwakha isithando somlilo

1. Susa iphepha le-mica lapho wakha isithando somlilo.

2. Isihlabathi se-crystal quartz sokwakhiwa kwesithando somlilo siphathwa ngale ndlela elandelayo:

(1) Ukukhetha izandla: ikakhulukazi susa izigaxa nokunye ukungcola;

(2) Ukuhlukaniswa kazibuthe: ukungcola kazibuthe kufanele kususwe ngokuphelele;

3. Impahla ye-ramming eyomile: kumele yomiswe kancane, izinga lokushisa lokumisa libe ngu-200℃-300℃, futhi ukugcinwa kokushisa kungaphezu kwamahora angu-4.

4. Ukukhethwa kwe-binder yesithando somlilo esiphakathi nendawo kagesi: sebenzisa i-boric anhydride (B2O3) esikhundleni se-boric acid (H3BO3) njengesibophezelo, futhi inani elingeziwe ngu-1.1% -1.5%.

Ukukhethwa kanye nengxenye yezinto zokwakha zesithando somlilo:

1. Ukukhethwa kwezinto zesithando somlilo: Kumele kuqashelwe ukuthi akuzona zonke izihlabathi ze-quartz ezine-SiO2≥99% ezingasetshenziswa njengezinto zokufakelwa kwesithando somlilo. Into ebalulekile ubukhulu bezinhlamvu zekristalu ye-quartz. Ukuqina kwezinhlamvu zekristalu, ukuncipha kwamaphutha e-lattice, kungcono. (Isibonelo, isihlabathi se-crystal quartz i-SiO2 sinokuhlanzeka okuphezulu, okumhlophe nokubonakala obala.) Uma ukhudlwana umthamo wesithando somlilo, ziphakama kakhulu izidingo zezinhlamvu zekristalu.

2. Ingxenye: Isilinganiso sesihlabathi sequartz solayini lwesithando somlilo: 6-8 mesh 10% -15%, 10-20 mesh 25% -30%, 20-40 mesh 25% -30%, 270 mesh 25% -30% .

Inqubo ye-Sintering kanye nezinga lokushisa le-sintering:

1. I-knotting of the lining: ikhwalithi yokufiphaza yolwelwesi ihlobene ngokuqondile nekhwalithi ye-sintering. Lapho uhlanganisa, ukusabalalisa usayizi wezinhlayiyana zesihlabathi kuyafana futhi akukho ukuhlukaniswa okwenzekayo. Isendlalelo sesihlabathi esinamafindo sinokuningi okuphezulu, futhi amathuba okuqhekeka ngemva kokucwiliswa kwe-sintering ancishisiwe, okuzuzisa ukuthuthukisa impilo yesevisi ye-lining yesithando somlilo.

2. Izansi yesithando somlilo esinamafindo: Ugqinsi lwesithando somlilo sicishe sibe ngu-280mm, futhi isihlabathi sigcwaliswa izikhathi ezine ukuze kuvinjelwe ukuminyana okungalingani yonke indawo lapho i-knotting yezandla, futhi ulayini lwesithando somlilo ngemva kokubhaka nokucwilisa akuminyene. Ngakho-ke, ukushuba kokuphakelayo kufanele kulawulwe ngokuqinile. Ngokuvamile, ubukhulu bokugcwalisa isihlabathi abukho ngaphezu kwe-100mm / isikhathi ngasinye, futhi udonga lwesithando somlilo lulawulwa ngaphakathi kwe-60mm. Abantu abaningi bahlukaniswa ngamashifu, abantu abangu-4-6 ishifu ngayinye, kanye nemizuzu engu-30 ukuze ifindo ngalinye lishintshwe, bazungeze isithando somlilo Jikelezisa kancane futhi usebenzise ngokulinganayo ukugwema ukuminyana okungalingani.

3. Udonga lwesithando somlilo: ubukhulu bomugqa wesithando somlilo buyi-110-120mm, ukwengeza izinto ezomile zokubopha ngamaqoqo, indwangu iyunifomu, ubukhulu bokugcwalisa abukho ngaphezu kwama-60 mm, futhi ukubopha kuyimizuzu eyi-15 (ukuhlanganisa ngesandla ngesandla. ) ize ilingane nonqenqema olungaphezulu lwendandatho yokungeniswa ndawonye. Isikhunta se-crucible asikhishwa ngemva kokuba i-knotting isiqediwe, futhi sisebenza njengokushisa kokungeniswa ngesikhathi sokomiswa nokucwiliswa.

4. Imininingwane yokubhaka kanye ne-sintering: Ukuze uthole uhlaka lwezendlalelo ezintathu zolayini lwesithando somlilo, inqubo yokubhaka neyokucwilisa ingahlukaniswa izigaba ezintathu:

5. Isiteji sokubhaka: ukushisa isikhunta se-crucible ku-600 ° C ngesivinini sika-25 ° C / h no-50 ° C / h ngokulandelanayo, futhi sigcine i-4h, inhloso ukukhipha ngokuphelele umswakama olayini lwesithando somlilo.

6. Isiteji se-semi-sintering: ukushisa ku-50 ° C / h kuya ku-900 ° C, ukubamba i-3h, ukushisa ku-100 ° C / h kuya ku-1200 ° C, ukubamba i-3h, izinga lokushisa kufanele lilawulwe ukuvimbela ukuqhekeka.

7. Isiteji se-sintering esiphelele: Ngesikhathi sokushisa okuphezulu, isakhiwo se-sintered se-crucible yesithando somlilo sikagesi esiphakathi siyisisekelo sokuthuthukisa impilo yaso yesevisi. Izinga lokushisa le-sintering lihlukile, ubukhulu besendlalelo se-sintering abanele, futhi impilo yesevisi iyancipha kakhulu.
