Abstract
The utility model discloses a separating machine screen used in Ni-P surfacing, which is formed by the heat treatment after a metal billet obtains the NI-P alloy gold plating by the method of the chemical plating or the electroplating. The utility model has strong abrasive resistance and can be used for sugar making, salt making, the gourmet power, the medicine, fertilizers, and separating machines of other chemical productions.
Description
A kind of screen cloth is used for the seperator of food, medicine, Chemical Manufacture.
Domestic existing Ni-based chromium plating seperator is with screen cloth acid-alkali-corrosive-resisting not, thereby use face is confined on the seperator of products such as the lower sugar of mother liquor acid basicity, monosodium glutamate.Have the used seperator of corrosive chemical products, all use the titanium screen cloth or the stainless steel mesh of foreign import, the price height, and need foreign exchange.And the seperator of anti-corrosion, wear-resisting nickel-phosphorus alloy coating screen cloth did not all occur both at home and abroad.
The purpose of this utility model is to provide the seperator screen cloth with nickel-phosphorus alloy coating that a kind of corrosion resistance is strong, wearability is high, thereby enlarges range of application, satisfies the domestic market needs.
Technical essential of the present utility model is on the metal bottom base of screen cloth, obtain nickel-phosphorus alloy coating with chemical plating or electric plating method after, form through heat treatment.
Domestic existing Ni-based chromium plating seperator screen cloth is done corrosion resistance test with the 2N solution of sulfuric acid or hydrochloric acid, in following two hours of the normal temperature erosion of chromium layer to the greatest extent, and under similarity condition, nickel-phosphorus alloy coating is not seen evidence of corrosion through sennight.Existing Ni-based chromium plating seperator is with chromium layer hardness 700～900HV(microhardness of screen cloth), and the hardness 800～1000HV of nickel-phosphorus alloy coating.Because the corrosion resistance of nickel-phosphorus alloy coating and the screen cloth height of the existing Ni-based chromium plating of hardness ratio.So can the expanded application scope on the seperator of salt manufacturing, medicine, food, chemical fertilizer and other Chemical Manufacture.
Accompanying drawing is the partial enlarged drawing of the seperator of nickel-phosphorus alloy coating with screen cloth.
Realize that embodiment of the present utility model can take multiple mode, the effect that variety of way obtains focuses on nickel-phosphorus alloy coating (2) near identical.Can select different metals, make screen cloth metal bottom base (1) with diverse ways, can form coating with chemical plating or electro-plating method, coating can make two-sided or single face.But best mode is an electroformed nickel substrate base, electroplates with nickel-phosphorus alloy coating, and coating is covered with the two sides of base at the bottom of the screen cloth, and one side can be slightly thinner.
Claims (1)
1, a kind of screen cloth is the seperator screen cloth of nickel-phosphorus alloy coating, has metal bottom base [1], it is characterized in that nickel-phosphorus alloy coating [2] be covered in metal bottom base [1] one side or two-sided on.
