Njira zopewera kugwiritsa ntchito muffle ng’anjo

The muffle ng’anjo angagwiritsidwe ntchito kusanthula mankhwala, kutsimikiza thupi ndi Kutenthetsa mbali yaing’ono zitsulo mu kutentha mankhwala mbali yaing’ono zitsulo mu ma laboratories a mabizinesi mafakitale ndi migodi, kafukufuku wa sayansi ndi mayunitsi ena. Pali mfundo zingapo zomwe muyenera kuziganizira mukamagwiritsa ntchito:

Pamene ng’anjo ya muffle imagwiritsidwa ntchito kapena kugwiritsidwanso ntchito pakatha nthawi yayitali yosagwira ntchito, ndikofunikira kuchita uvuni. Uvuni uyenera kukhala kutentha kwa 200 ° C kwa maola anayi. Maola anayi kuchokera 200 ° C mpaka 600 ° C. Mukagwiritsidwa ntchito, kutentha kwa ng’anjo sikuyenera kupitirira kutentha kowonjezera kuti musawotche zinthu zamagetsi zamagetsi. Lekani kuthira zakumwa zosiyanasiyana ndi zitsulo zosungunuka mosavuta m’ng’anjo. Ng’anjoyo imayendetsedwa ndi kutentha kosachepera 50 ℃, ndipo waya wa ng’anjoyo amakhala ndi moyo wautali.

M’pofunika kuti muffle ng’anjo ndi wolamulira ntchito mu malo chinyezi wachibale si upambana 85%, ndipo palibe conductive fumbi, mpweya waphulika kapena mpweya zikuwononga. Pamene zipangizo zachitsulo ndi mafuta kapena zina ziyenera kutenthedwa, mpweya wambiri wosasunthika umakhudza ndi kuwononga maonekedwe a chinthu chotenthetsera magetsi, kuwononga ndi kufupikitsa moyo wake. Choncho, kutentha kuyenera kupewedwa panthawi yake ndipo chidebecho chiyenera kusindikizidwa kapena kutsegulidwa bwino ndi kutsukidwa.

Wowongolera ng’anjo ya muffle ayenera kukhala ndi kutentha kozungulira kwa 0-40 ℃. Musatulutse thermocouple mwadzidzidzi pa kutentha kwakukulu kuti muteteze jekete kuti lisaphwanyike.

Malinga ndi zopempha za luso, fufuzani nthawi zonse ngati mawaya a ng’anjo yamoto yotentha kwambiri ndi yabwino kwambiri, ngati cholozera cha chizindikirocho chikugwedezeka ndikukhala pamene chikuyenda, ndipo gwiritsani ntchito potentiometer kukonza maonekedwe a maginito, demagnetization, kukulitsa waya, ndi shrapnel Kuchulukitsa zolakwika chifukwa cha kutopa, kuwonongeka bwino, ndi zina zambiri. Nthawi zambiri amalimbikira kuyeretsa ng’anjo yamoto kuti muchotse ma oxide ndi zinthu zina mung’anjo nthawi.
