Nzira yekuchengetedza sei muffle furnace?

Muffle furnace inowanzonzi marudzi anotevera: choto chemagetsi, choto chekudzivirira, Maofu furnace, uye muffle furnace. Iyo muffle vira ndeyeyakajairwa yekudziya yemidziyo, iyo inogona kukamurwa kuita bhokisi choto, chubhu choto uye crucible choto zvinoenderana nechitarisiko uye chimiro. Izvi zvinotevera zvinotsanangura nzira yekuchengetedza yemoto muffle:

1. Apo mufuri wemoto unoshandiswa kamwe chete kana kushandiswa zvakare mushure menguva refu yekushanda, inofanira kubikwa. Nguva yehovhoni inofanira kuva 200 ° C kusvika 600 ° C kwemaawa mana. Paunenge uchishandiswa, tembiricha yechoto haifanire kudarika tembiricha yakatarwa, kuitira kuti isapisa chinhu chinopisa. Zvinorambidzwa kudira zvinwiwa zvakasiyana-siyana uye zviri nyore kunyungudika simbi muchoto. Iyo muffle furnace inoshanda pane tembiricha iri pasi pe50 ℃ pazasi petembiricha yakakwira, uye waya yechoto ine hupenyu hurefu.

2. Iyo muffle furnace uye controller inofanira kushanda munzvimbo iyo hunyoro husingapfuuri 85%, uye hapana guruva rinoita, gasi rinoputika kana gasi rinoparadza. Kana iyo simbi yesimbi ine girisi kana yakafanana inoda kupiswa, huwandu hukuru hwegasi hunoputika huchakanganisa uye hunokanganisa pamusoro peiyo yemagetsi kupisa chinhu, zvichiita kuti iparadzwe uye kupfupisa hupenyu. Naizvozvo, kupisa kunofanirwa kudzivirirwa nenguva uye mudziyo unofanirwa kuvharwa kana kuvhurwa zvakanaka kuti ubvise.

3, iyo muffle furnace controller inofanirwa kugumira kushandisa mune ambient tembiricha ye0-40 ℃.

4. Maererano nezvinodiwa zveunyanzvi, gara uchitarisa kana wiring yevira remagetsi uye mutongi ari mumamiriro akanaka. Iyo tembiricha-yekuyera thermocouples yakabatana kune controller inogona kukanganisa mutongi, zvichiita kuti mutongi aratidze kukosha kusvetuka mavara, uye kukanganisa kuyerwa kunowedzera. Iyo yakakwirira tembiricha yechoto, zvakanyanya kujeka chiitiko ichi. Nokudaro, simbi yekudzivirira chubhu (shell) ye thermocouple inofanira kunge yakanyatsogadziriswa, uye kana zvichidiwa, shandisa thermocouple ine katatu-waya kubuda. Muchidimbu, *** matanho anofanirwa kutorwa kuderedza kupindira.

5. Usabudisa thermocouple pakarepo pakupisa kwepamusoro kudzivirira jekete kubva pakuputika.

6. Chengetedza kamuri yevira yakachena uye bvisa okisidhi muchoto munguva.

7. Panguva yekushandiswa, paunenge uchishandisa zvinhu zvealkaline kusanganisa sampuli kana kupisa madhipoziti muchoto, mamiriro ekushanda anofanirwa kunyatsodzorwa, uye ndiro inopikisa inofanira kuiswa pasi pechoto kudzivirira kuparara kwechoto.
