Description

A kind of manufacturing process of ceramic water channel tap
Technical field
The invention belongs to supply equipment technical field, and in particular to a kind of manufacturing process of ceramic water channel tap.
Background technology
Tap is last one of outpost of the tax office that municipal network water supply enters after family, is the valve of the stream of a control water only Door.The species of tap is a lot, is distinguished according to structure, can be divided into several taps such as single-plicate, twin and tri-coupling type, separately Outside, also monolever and dual-handle point.Single-plicate can connect cold water pipe or hot-water line;Twin can connect cold and hot two pipes simultaneously Road.Distinguished according to material, then can be divided into stainless steel faucet, cast iron bibcock, overall plastic tap, brass screw down bib cock, zinc again Alloy material tap and the polymer composite fire hose are first-class.Various faucet performances are different, are suitably applied different occasions.
The main tap used is metal faucet currently on the market, and its housing parts is using brass, aluminium alloy, no Become rusty the multiple materials such as steel, then assembles to form the tap with complete function by each part.Due to different water channels and valve element Performance is different, and the property of this tap is also not quite similar, and some materials occur old under the immersion of long-time current, easily The problem of change, corrosion or content dissolution.Some poisonous and hazardous materials may be contained in some resin materials, and some are closed Some heavy metal substances may also be contained in the smelting process of gold, these materials are once dissolved in water, and drinking for a long time can Harm can be brought to user health.
The appearance of the taps of material such as some later ceramics so that the anti-oxidant and decay resistance band of fire hose head material To improve, also solve water body may contaminated hidden danger, but ceramic material has impact resistance poor, freezing tolerance Shortcoming that is weak, easily bursting, the service life that these also result in ceramic tap is relatively low.
The content of the invention
For problem above, it is an object of the invention to provide a kind of manufacturing process of ceramic water channel tap, using this The tap of technique productions, with corrosion-resistant, anti-aging feature, resist cold strong shock resistance, and very safety will not occur Harmful substance dissolution.
A kind of manufacturing process of ceramic water channel tap, including following manufacturing step:

(2) water channel is molded:Water channel blank is made in pottery mud hot die-casting molding, calcining dewaxing, calcining are carried out to water channel blank Temperature is 1350-1380 DEG C, and calcination time 3-4h naturally cools to normal temperature after calcining, then carries out surface grinding process, obtains Required ceramic water channel.
(3) prepared by aluminum alloy casing:Aluminium alloy extrusions is sent into extruder, shell group is processed using extrusion forming technology Part, then edge of blank cutting is polished smooth, obtains shell blank, shell blank is sent in electroplating pool and plated in outer surface Last layer chromium metal level.
(4) tap is assembled:Water channel and shell, which are assembled, to be put into mould and fixed, is filled in organic polymer filler Die cavity gap, after after cooling and shaping in mould, be removed from the molds carry out refine processing, then by the ceramic cartridge of tap, Go out the parts groups such as the network of rivers, sealing ring, clamp nut and install whole, ceramic water channel tap needed for obtaining.
It is preferred that, the powder in step (1) crosses 250-300 mesh sieves after ball mill grinding.
It is preferred that, the temperature of whipping process is 65-70 DEG C in step (1).
It is preferred that, ceramic water channel carries out curing in water after the completion of preparing in step (2), and curing time is 1-2d.
It is preferred that, aluminium alloy extruded shaping uses extrusion forming technology in step (3).
It is preferred that, the chromium metal coating thickness in step (3) is 0.05-0.1mm.
It is preferred that, organic polymer filler in step (5) for polycaprolactone.
It is preferred that, the filling temp of the organic polymer filler in step (5) is 60-65 DEG C.
Compared with prior art, the present invention has following beneficial effect:
The tap of the manufacturing process manufacture for a kind of ceramic water channel tap that the present invention is provided, due to the master of inner waterway It is ceramics to want material so that it has a good acid-alkali-corrosive-resisting, oxidation resistance, for a long time using being not easy to hair in flowing water Raw aging;Property is stable, and any poisonous and harmful dissolution is not had, for a long time using also not resulting in water pollution;Can be not With the use of aquatic environment from different places, tap service life is long.
The sheathing material of the type tap is chromium plating aluminium alloy, and internal water channel, valve element and seals and other component can be risen To good protective effect, infringement of the external environment condition to internal part is prevented;Organic polymer is filled between shell and water channel Filler, can play cushioning effect, allow the tap to resist stronger external impact.In addition, the shell of chromium plating also has Good aesthetic.
