Aplikasyon à tamisage ekipman nan pwodiksyon ultrafine Zenk poud

Superfine zinc powder is a gray metal regular spherical fine powder produced by distillation in a uniquely designed zinc powder furnace with a density of 7.14g/cm3, melting point of 419 degree and boiling point of 907 degree . Insoluble in water, soluble in acid and alkali, ammonia water, with strong reducibility. It has the advantages of high activity, good corrosion resistance, environmental protection, less surface oxidation, smooth and neat spherulite surface, good dispersity, uniform particle size, large specific surface area, small loose weight, high coating covering efficiency, good chemical reduction effect and so on. Stable in dry air, easy to agglomerate in humid air, and form basic carbonate and cover the surface of particles. Its average particle size is between 3 and 4UM. As the key raw material of zinc-rich anticorrosive coating, it is widely used in coating of large steel components that are not suitable for hot plating and electroplating, such as large outdoor steel structures, ocean engineering, Bridges, pipelines, ships and containers, etc. In addition to being used for zinc-rich anticorrosive coating, zinc powder products are also used for mechanical galvanized production of steel products such as screws, nails and nails. With the development of China's economy, the demand for ultrafine zinc powder has also increased sharply, so the demand for ultrafine zinc powder special sieve is increasingly strong. But in the early 1990s, China's ultrafine screening equipment is almost entirely imported, but there is no ultrafine zinc powder special sieve, which directly increases the cost of ultrafine zinc powder, reduce the profits of enterprises.

Anpil manifaktirè chwazi ekran koule lè ekran poud zenk, prensip la nan koule lè se pa wotasyon wo -vitès nan wou klasman an, yo fè distenksyon ant rafineman nan poud zenk: wou klasifikasyon ak pati fiks nan espas sa a se piti anpil. , se zòn chofaj la, lè poud zenk aktif la ap vin fonn agglomerate, e menm combustion. Caking pral fè pwodwi a san kalifye, ak poud zenk pa ka boule dife louvri, pa fasil jwenn, pafwa jiskaske trè grav jwenn dife, pèt lou. Se pa sèlman tout ekipman an pral abandone, men pa gen okenn garanti sekirite.

Konpayi nou an apre ane nan rechèch, sou baz ekran koule lè, konbine avèk bezwen aktyèl yo, pou karakteristik sa yo nan poud zenk yon nouvo ekipman tès depistaj, poud zenk pa pral chofe agglomerate oswa konbisyon espontane nan machin nan Van. Ekipman tès depistaj sa a konpoze de sistèm lame ak total pou retire pousyè, travay sik presyon negatif, pa gen pousyè; Gen yon kouch seleksyon koryas matyè premyè nan lame a, ki genyen batay la pwoblèm nan gwo patikil kraze nèt la; Materyèl la anvan tout koreksyon antre nan zòn nan atomize apre atomize respire nan espre nan ekran may 500, pasaj la presyon negatif lè nan nèt la nan pèseptè a, nan kalòj la fèmen lè wring egzeyate anbalaj la pwodwi fini, men se nèt la voye nan pati anba a nan plak ekran an anba netwayaj la toubiyon; Nan moman sa a, gen yon ti kras amann poud tou desann, yo pral vire moute pa sistèm nan seleksyon segondè lè, flite ankò sou ekran an may 500; Finalman, ekran an vibre nan priz la materyèl koryas, ap tann pou yon sèten kantite presyon negatif simonte, otomatikman louvri pòt la presyon negatif, egzeyat. Presizyon nan poud koryas se jeneralman ant -200 may plis 500 may, efè a se trè evidan.
