Method for preparing zinc oxide desulfurizer using zinc oxide white powder 99.7%

Faoi láthair, áirítear ar na modhanna chun díshalannóirí ocsaíd since a ullmhú le púdar bán ocsaíd since 99.7%: modh meascáin thirim, modh deascadh, agus modh glóthach sol. Is modh traidisiúnta é an modh cumasc tirim, agus úsáidtear an modh deascadh níos minice anois, cé gur modh nua é an modh sol-fhoirmiú le déanaí.

1) The dry blending method is to combine zinc oxide white powder 99.7% and other additives, pore formers, and binders by adding appropriate amounts of water, organic solvents, stirring, grinding, mechanical crushing, ultrasonic waves, vibration and other smashing methods. Mix them uniformly, and then extrude them into different shapes such as flakes, strips, or spheres through extruders or tablet presses, then dry them in an oven and roast them in a muffle furnace to obtain samples. This manufacturing method is simple, large in production capacity, and low in operating costs. The biggest disadvantage is that the desulfurizer of this process is not easy to make the components of the desulfurizer highly dispersed and uniform. The same chemical components are not as active and thermally stable as those prepared by the precipitation method. Good desulfurizer.

2) An modh chun desulfurizer ocsaíd since a ullmhú le púdar bán ocsaíd since 99.7%. Amach anseo, cuirfear modh deascadh aonfhoirmeach agus modh sol-fhoirmiú in ionad an mhodha mheasctha de réir a chéile. Tá an modh deascadh aonfhoirmeach difriúil ón modh deascadh díreach sa mhéid is nach n-imoibríonn agus go deascann an deascán breise leis an ábhar réamhtheáite, ach ar dtús scaoiltear an deascán go mall agus go haonfhoirmeach sa chrios neamhsháithithe. Úsáideann an modh sol-fhoirmiú collóidigh a bheith scaipthe go mór i gcáithníní nana-mhéid chun díshalannóirí a tháirgeadh.
