Nature The white or the decadent powder, the density 5.606, the melting point 1975℃, is one kind of intermediate oxide, does not dissolve in the water or the ethyl alcohol, dissolves in the acid and alkali solution. When high temperature assumes the yellow, after the cooling, restores the white. Outward appearance White powder Project Top-quality product Second product Third-class product The zinc oxide (does idea)%≥ 98 95 90 The lead monoxide (counts by Pb %≤) 0.0055 0.05 0.059 Cd(Cd) 0.005 0.004 0.048 As(AS) 0.004 0.0042 0.052 H2O(H2O) 0.2 0.2 0.22 Characteristic 1,st, the zinc oxide and other zinc source compare, unit zinc cost obvious low, favors the low feed additive the cost, the recruitment is equal to the sulfuric acid monohydrate zinc 44%, seven water zinc sulfate 28% 2,nd, the zinc oxide to do the powdery zinc source, the stability is good in the feed, does not contain water, does not agglomerate, the invariability, is advantageous for the feed processing and the standing storage, is small to the feed Vitamin influence. 3,rd, the zinc oxide makes the zinc source, compared to other zinc source change by the animal absorption, is made up the zinc effect to be good. Major technique target High quality conforms to GB/T 3185-92 (by percentage idea) Memory Should in cool, dry, ventilates place the airtight preservation Packing Plastic knitting bag inside lining plastic bag packing, each bag of net weight 25 kilograms.
