Crucible hman dan tur leh hman dan tur kaihhruaina

Crucibles hi laboratory leh industrial production-a high-temperature melting, heating, emaw reaction atana hman tur container pawimawh tak a ni. An hman dan dik hian experimental safety leh result dikna a nghawng nghal vek a ni. A hnuaia tarlan te hi standard crucible handling procedure leh fimkhur dan tur te an ni.

1. Inbuatsaihna

Hman hmain crucible hi a integrity enfiah hmasa phawt la, a chhe lo emaw, a chhe lo emaw a awm lo em tih enfiah hmasa phawt ang che. Material (quartz, ceramic, graphite ang chi) temperature tolerance chu a lum lutuk loh nan teh rawh. Internal stress tihbo nan crucible thar hman hmasak hmain preheat hmasa phawt a tha. Tin, grip him leh high-temperature resistance neih theih nan matching crucible tongs te pawh thlang bawk ang che.

2. Loading leh Placement

Crucible-a material i dah dawnin, a lum laiin a luang chhuak lo turin a capacity hmun thuma ṭhena hmun hnih{0}} aia tam loah tihtlem tur a ni. Thil chi hrang hrang (metal powder ang chi) i khawih chuan venhimna layer hmangin khuh la, a nih loh leh addition rate chu ti hniam rawh. Crucible chu heat-resistant pad emaw dedicated stand emaw-ah dah la, a hnuai lamah pawh lumna inang tlang taka awm theih nan local overheating leh cracking a awm loh nan.

3. Heating leh Process Control

Heating hi zawi zawiin tih tur a ni a, chu chu thermal shock thlen thei tur a lum nghal loh nan. Muffle furnace emaw electric furnace emaw hman hunah chuan target temperature thlenga 5-10℃/min rate-a tihsan a tha a, observation port kaltlangin a dinhmun enfiah a tha bawk. Stirring emaw sampling emaw a ngai a nih chuan invenna hmanrua bun a ngai a, hmanraw bik hman a ngai bawk. Crucible body nena direct contact hi khap tlat a ni.

4. Cooling leh Post-Processing tih dan

A lum hnuah crucible chu natural takin room temperature thlenga lum turin dah tur a ni. Rapid cooling (tui hmanga silfai ang chi) khap a ni. Crucible chu a lum laiin sawn chuan a puak thei a ni. I sawn hmain temperature him taka a lum hma chu nghak rawh. Hman zawhah a la awm zawng zawng chu silfai nghal la, chutiang chuan thil chhe thei thilte chu a chhung lam bang-ah a innghat lo va, a tichhia lo ang.

5. Hriselna atana fimkhur dan tur

Operation chhung zawng hian high-temperature gloves, goggles leh invenna thawmhnaw ha la, kang thei thil lakah pawh hla takah awm rawh. Crucible a chhe a nih chuan hman kha titawp nghal la, a hnah te chu uluk takin paih la, chutiang chuan a hrual leh boruak bawlhhlawh a awm loh nan.

Experimental safety leh data rintlakna atan crucible hman dan dik a pawimawh hle. Procedure khauh taka zawm hian hlauhawmna nasa takin a tihziaawm thei a, hmanrua dam chhung pawh a ti rei thei bawk.
