Tionchar an phróisis bhrionnaithe ar eagraíocht agus airíonna barra tíotáiniam Gr2
Apr 07, 2024
Is iad ábhair bhrionnú barra tíotáiniam Gr2 den chuid is mó cóimhiotail tíotáiniam íon agus tíotáiniam de chomhdhéanamh éagsúla, agus tá slata tíotáiniam, dtinní, púdar miotail agus miotail leachtacha ag staid bhunaidh an ábhair. Tugtar an cóimheas brionnú ar an gcóimheas idir limistéar trasghearrtha na miotail roimh dhífhoirmiú go dtí an limistéar trasghearrtha tar éis dífhoirmithe. Tá caidreamh iontach ag rogha cóimheas brionnú ceart, teocht teasa réasúnta agus am sealbhaíochta, tús réasúnta agus teocht bhrionnú deiridh, méid réasúnta dífhoirmithe agus luas dífhoirmithe chun cáilíocht an táirge a fheabhsú agus costais a laghdú. Is barraí cruinne nó cearnacha iad gaibhneachta ginearálta beaga agus meánmhéide mar bhearnaí. Tá eagraíocht gráin barra agus airíonna meicniúla aonfhoirmeach, go maith, cruth cruinn agus méid, cáilíocht dromchla maith, éasca le táirgeadh mais a eagrú. Chomh fada is go bhfuil an teocht teasa agus na coinníollacha dífhoirmithe rialaithe go réasúnta, ní gá is féidir dífhoirmiúchán mór brionnú a bhrionnú le gaibhneachta feidhmíochta den scoth.
