Mukayaka, zonyansa zamtundu wazomwe zili m'chitsanzo zimakhala zokhazikika (monga sodium kolorayidi, potaziyamu chloride, sodium sulfate, etc.), ngati si chifukwa cha kutentha ndi kutuluka kwa nthunzi, njirayi ingagwiritsidwe ntchito kudziwa phulusa mu chitsanzo.

[Njira Yodziwira] Ikani chivundikiro cha ceramic (kapena nickel crucible) pa ng'anjo yamagetsi yotentha kwambiri (mwachitsanzo, ng'anjo yamoto) kapena lawi lamoto, kutentha mpaka kulemera kosalekeza pafupifupi (pafupifupi ola limodzi), kusunthira ku chowumitsira cha calcium chloride. ndi ozizira kutentha kwa chipinda. Chivundikiro cha crucible chinayesedwa palimodzi pamlingo wowunikira ndikuyika G1 g.

Mu crucible kale kulemera, kutenga chitsanzo yoyenera (malingana ndi phulusa mu chitsanzo, ambiri otchedwa 2-3 magalamu), anati 0.0002 magalamu, crucible chivindikiro pakamwa pafupifupi atatu kotala, ndi otsika moto pang'onopang'ono Kutentha crucible, kupanga chitsanzo pang'onopang'ono carbonization. , pambuyo pa crucible mu ng'anjo yamagetsi (kapena lawi la gasi), osachepera 800℃kuyaka kwa pafupifupi kulemera kosalekeza (pafupifupi maola atatu), kusamukira ku chowumitsira cha calcium chloride, utakhazikika kwa firiji, masekeli. Ndi bwino kuwotcha pambuyo pa maola a 2, kuziziritsa, kulemera, ndikuwotcha kwa ola la 1, kenako kuzizira, kulemera, monga masekeli awiri motsatizana, kulemera kumakhala kosasinthika, ndiye kumatanthauza kuti watenthedwa kwathunthu, ngati kulemera kumachepetsedwa. pambuyo kuwotcha yachiwiri, ndiye ayenera wachitatu kuwotcha, kutentha mpaka ofanana ndi kulemera zonse, anapereka G magalamu.

(G-G1) / chitsanzo kulemera x100= imvi%

[Zindikirani] - -Kukula kwachitsanzo kungathe kutsimikiziridwa molingana ndi kuchuluka kwa phulusa mu chitsanzo, phulusa laling'ono, lingatchulidwe za 5 magalamu a chitsanzo, phulusa lachitsanzo, likhoza kutchedwa pafupifupi 2 magalamu a chitsanzo.

2. Kutalika kwa nthawi yoyaka kumadalira kulemera kwa chitsanzo, koma kuyaka kumakhala kofanana ndi kulemera kosalekeza.

3. Kusiyana koyezera komwe kumayaka kawiri motsatizana kuli bwino kukhala 0.3 mg pansipa, kusiyana kwakukulu sikungapitirire 1 mg, kutengera kulemera kosalekeza ndiko.
