Problems solved by technology

But now the faucets on the market are basically made of copper and zinc alloy materials, which will cause secondary pollution of water quality. If used for a long time, the electroplating layer will fall off or copper rust will grow. Lead and copper rust will pollute tap water and damage people's health. Stainless steel faucets do not need electroplating, the manufacturing process will not pollute th

Embodiment 1

[0026] An anti-scaling stainless steel faucet, the base body is cast with 0Cr19Ni10Nb, the surface is densely covered with a micropit structure with a coverage rate of not less than 99%, a particle size of 5 μm-8 μm, and a hexamethyldisiloxane hydrophobic film layer is fixed.

[0027] The manufacturing method of the above-mentioned scale-resistant stainless steel faucet comprises the following steps:

[0028] 1) Preparation before production

[0029] ① Raw material preparation: Prepare 1Kg of 0Cr19Ni10Nb stainless steel masterbatch and sufficient amount of hexamethyldisiloxane by weight;

[0030] ② Preparation of modified process materials: prepare a sufficient amount of silica powder with a particle size of 5 μm-8 μm;

[0031] ③Equipment and tooling preparation: prepare sandbox, disposable faucet imitation wax mold, sufficient amount of ethyl silicate hydrolyzate, sufficient amount of powdery bauxite clinker with a particle size of 800 mesh, and sufficient amount of powdered...

Embodiment 2

[0045] The whole is consistent with Example 1, the difference is:

[0046] The manufacturing method of the above-mentioned scale-resistant stainless steel faucet comprises the following steps:

[0047] 1) Preparation before production

[0048] ① Raw material preparation: Prepare 0Cr19Ni10Nb stainless steel masterbatch 1.2Kg and sufficient amount of hexamethyldisiloxane by weight;

[0049] 2) Investment manufacturing

[0050] ②Immerse the clean wax model into the ethyl silicate hydrolyzate, shake it up and down for 10 seconds, then take it out, and then evenly spread the mixed powdery alumina-vanadium clinker on the surface of the clean wax model coated with the ethyl silicate hydrolyzate , to obtain the wax model to be processed;

[0051] ③Place the wax model to be treated obtained in step ② in a room temperature environment with a relative humidity of 65%, wait for it to dry and solidify automatically, and then immerse it in ethyl silicate hydrolyzate;

Abstract

The invention discloses an incrustation-resistant stainless steel faucet and a manufacturing method thereof. A base body of the incrustation-resistant stainless steel faucet is cast through OCr19Ni10Nb, micro-pit structures with the coverage rate not lower than 99% and the grain size ranging from 5 microns to 8 microns are densely distributed on the surface, and a hexamethyldisiloxane hydrophobicfilm layer is fixed. Austenitic stainless steel serves as the base body of the incrustation-resistant stainless steel faucet, the technology is simple and mature, the surface has the lotus leaf effect, and cleaning is easy.

Description

technical field [0001] The invention relates to the field of faucet manufacture, in particular to a scale-resistant stainless steel faucet and a manufacturing method thereof. Background technique [0002] Stainless steel, because it is safe and lead-free, has no corrosion and seepage, and will not cause secondary pollution to water quality, is actually very suitable for making faucets. But now the faucets on the market are basically made of copper and zinc alloy materials, which will cause secondary pollution of water quality. If used for a long time, the electroplating layer will fall off or copper rust will grow. Lead and copper rust will pollute tap water and damage people's health. Stainless steel faucets do not need electroplating, the manufacturing process will not pollute the environment, keep the water quality pure and hygienic, and will not need to be replaced frequently due to the peeling off of the electroplating layer. [0003] However, the stainless steel fauce...
