A multifunctional faucet and its manufacturing method

Abstract

The invention discloses a multifunctional faucet and a manufacturing method thereof; the multifunctional faucet comprises a base body and a coating attached on the base body; the substrate is composed of a valve body, a valve element, a handle and a water opening; the mixture of the coating is prepared from base stock, polytetrafluoroethylene aqueous dispersion, molybdenum disulfide, bronze powder, titanium dioxide, polyPhenylene sulfide, titanate coupling agent, defoaming agent, leveling agent, texanol alcohol ester in percentage; the manufacturing method comprises the steps of treatment of the base body, covering with the coating, sintering at high temperature, production test and storage; the multifunctional faucet overcomes the defects of serious environmental pollution to the product origin resulting from the electro-plating treatment method for the surface layers of the present faucets, single function of the faucets, easy corrosion to the surfaces, easy rusting and short service life and the like; and the manufacturing method is applicable to manufacturing various faucets, cast iron pipes and metal pipes.

Description

technical field [0001] The invention relates to a multifunctional faucet and a manufacturing method thereof. Background technique [0002] The surface treatment of the existing faucet shell adopts the electroplating layer treatment method, and the discharge of wastewater, waste residue, and waste electroplating solution such as pickling and alkali washing of electroplating is the biggest source of polluting the land and water resources and the environment, and the acid-alkali washing It takes 40 to 60 years for the land through which waste water, waste residue, and waste electroplating solution are discharged to recover and sow crops. Acid and alkali: These substances will change the pH value of the water and affect the performance of the water. Cyanide: It is highly toxic and will kill various species. species of aquatic organisms, metal ions: nickel, chromium, and mercury ions are absorbed by Becker-like organisms and plants, and will accumulate in their bodies. Once peopl...

[0002] The surface treatment of the existing faucet shell adopts the electroplating layer treatment method, and the discharge of wastewater, waste residue, and waste electroplating solution such as pickling and alkali washing of electroplating is the biggest source of polluting the land and water resources and the environment, and the acid-alkali washing It takes 40 to 60 years for the land through which waste water, waste residue, and waste electroplating solution are discharged to recover and sow crops. Acid and alkali: These substances will change the pH value of the water and affect the performance of the water. Cyanide: It is highly toxic and will kill various species. species of aquatic organisms, metal ions: nickel, chromium, and mercury ions are absorbed by Becker-like organisms and plants, and will accumulate in their bodies. Once people eat these contaminated foods by mistake, they will be poisoned; wastewater discharge such as: chrome-plating wastewater The wastewater produced by plating 10³m² workpieces contains 37kg of hexavalent chromium, and 90% of the amount of cyanide is excluded from the cyanide wastewater. , lung cancer, heart and other diseases, in the European Union and the United States and many other countries have imposed strict restrictions on hexavalent chromium and chromium-containing products, electrochrome plating and even Dacromet have reformed into chrome-free alternative products; and the faucet industry has It is a chrome-plated product, and no organisms and fish can be seen in the ponds, creeks, and pools around the electroplating area of ​​these faucets; secondly, the acid, alkali, salt, mist and amine gas in the home improvement kitchen are the most likely to cause corrosion to the faucet , especially the sulfur-containing soot in the kitchen when burning coal in rural areas, the electroplating faucet has been used for less than 3-6 months, and the surface electroplating layer is oxidized and rusted, which makes people's eyes full of rust stains and makes the kitchen and bathroom unsightly. Defects that seriously affect the service life of the product
