Ntxiv txog 3-4 Tbsp ntawm Borax rau txhua khob dej hauv koj cov tshuaj. Do kom txog thaum Borax dissolves nyob rau hauv dej. Koj xav kom cov dej ntshiab vim yog dej nag ces koj siv lead ua yuav huab.

Tsuas yog li ntawd, ntau npaum li cas Borax koj yuav tsum ua kom muaju?

Rau txhua khob dej, ntxiv 3-4 tablespoons ntawm Borax . Do kom txog thaum cov dej ntshiab thiab feem ntau ntawm cov Borax yog yaj. (Kuv feem ntau ua 3 khob dej ib zaug.) Ntxiv thiab nplawm kom txog thaum cov dej tsis so lub Borax.

Yog vim li cas borax ua crystals? Crystals tuaj yeem tsim tau thaum cov kua supersaturated uas muaj cov ntxhia yaj hauv cov dej txias. Hauv qhov kev ua no, cov tshuaj supersaturated tau ua los ntawm cov dej kub thiab borax (ib soft siv lead ua ). Raws li kev daws txias, cov dej molecules tuaj ze ua ke dua ua rau kev sib sau borax siv lead ua txhawm rau txhawm rau txhawm rau ntxuav cov yeeb nkab.

Ua li no, dab tsi zoo li borax crystals?

Borax yog ib qho piv txwv ntawm siv lead ua - "Ib qho khoom nrog tiaj tus sab thiab symmetrical puab vim hais tias nws cov molecules yog teem nyob rau hauv ib tug tshwj xeeb, rov ua qauv." Txhua siv lead ua muaj tus qauv rov ua raws li nws qhov tshwj xeeb puab . Tej zaum lawv yuav loj lossis me, tab sis lawv txhua tus muaj tib yam " puab ".

Yuav siv sijhawm ntev npaum li cas los ua borax siv lead ua?

Tawm thaum hmo ntuj Cov dej hauv cov yeeb nkab ntxuav yuav tsum daim ntawv siv lead ua hauv 12-24 teev tom ntej. Ntev npaum li koj tso lawv lawm ces lawv yuav loj tuaj. Nco ntsoov tias tsis muaj ib qho ntawm cov yeeb nkab ntxuav tau kov ib leeg lossis ob sab ntawm lub hub kom lawv loj tuaj yeem loj tuaj.
