Abstract
The utility model relates to a fishing net fall, in particular to a ceramic fishing net fall, which comprises a cylindrical body. The body is axially provided with a cylindrical hole capable of containing a rope to penetrate through, and a glaze layer with a thickness of 10-100um is further arranged on the surface of the body. Being different from an old-style fishing net fall adopting harmful lead as raw materials of a body, the ceramic fishing net fall adopts harmless ceramics to replace the original harmful lead as raw materials, the glaze layer has corrosion resistance, and the ceramic fishing net fall is also a green and environment-friendly product without any pollution to offshore, and also has the great advantage of greatly reduced production prices compared with the lead with higher price.
Description
Technical field
The utility model relates to a kind of fishing net and weighs down, and particularly a kind of ceramic fishing net weighs down.
Background technology
Present to fish for the fishnet major part all roughly be such structure: the net that certain mesh size is arranged, the fishing net that all is provided with a determining deviation on its rope upper and lower portion, top rope weighs down, the fishing net that can bag the game with formation.It is cylindrical inner hollow that fishing net weighs down with fishing net, and rope passes wherein, and fishing net weighs down and can rotate by the wiring rope.Fishing net weighs down body and is generally made by heavy metal lead.But it is plumbous with polluted water.Moreover, because the metallic lead price is higher, also a very big burden concerning the fisherman.Korea S openly speciallys permit fishing net in No. the 80505th, the communique and weighs down and made by iron or stainless body etc., make fishing net in use can effectively prevent plumbous pollution, wearing and tearing and can partly reduce cost, but because iron is prone to the situation of winding when operation after the corrosion in seawater; The body that uses stainless body material to make is not perishable, but cost is too high.
The utility model content
The utility model is just for addressing the above problem.
The technical solution of the utility model is: ceramic main body of the present utility model is cylinder, and the columniform hole that rope passes that holds is arranged vertically, and described body surfaces also has the glaze layer.
The thickness of glaze layer is 10-100um.If thickness is less than 10um, the glaze layer is thin excessively, and damage easily makes net weigh down smoothness decline and twines; If the thickness of glaze layer has surpassed 100um, though can make wearability, corrosion resistance etc. have raising, noneconomic problem will occur on production cost.
The utility model changes the consistent lead with toxic that uses, replace with nontoxic pottery, the appearance sintering ceramic glaze layer of making pottery, being greatly increased aspect wear-resisting and the corrosion resistance, is that the Green Product that seawater is polluted is understood in a kind of brand-new not worrying fully.
Because need not be plumbous, fishing net of the present utility model be when repairing, and also without any harm, this also is another target that this patent is pursued to human body.
Usually fish for fishing net service life at 3-6 month, generally also can be discarded together with plumbous fishing net bob of making, thus to huge financial burden of numerous fishermen Lai Shuoshi.This utility model has been abandoned high price lead in the past and has been the pattern of bulk stock, adopts the low price pottery to make, and makes production cost reduce greatly, and economical and practical property economically is the another feature of this product.
Description of drawings
Fig. 1 is a surface structure schematic diagram of the present utility model.
Fig. 2 is Figure 1A-A line sectional view and partial enlarged drawing.
Fig. 3 is an actual user mode schematic diagram of the present utility model.
Wherein: the utility model 100, body 10, glaze layer 20.
Embodiment
The employed carcass material of the utility model is to add the part grog in the clay or sand mixes, and glaze is leaded and fusible glaze boron, and cost is all very low.
The ceramic glaze layer that the utility model forms need reach 10-100um, if thickness less than 10um, the glaze layer is thin excessively, the glaze layer sustains damage easily; If the thickness of glaze layer has surpassed 100um, owing to the blocked up wearability that causes, corrosion resistance etc. have raising so, but noneconomic problem will occur on production cost.Certainly ceramic thickness does not need to produce by above-mentioned thickness fully, can be according to specific circumstances, and specifically the service condition that needs is regulated the thickness of ceramic glaze layer.
The method for coating of ceramic glaze layer of the present utility model adopts common method for coating, and by 2～3 hours fire, firing of pottery was not special feature of the present utility model under 720～1000 degree celsius temperature.
Embodiment one:
Commercially available low-temperature glaze is coated in them on carcasses of heavy 200 grams that mold pressing makes according to common method for coating, through 3 hours, makes the thickness of ceramic glaze layer reach 20um under 720 degrees centigrade condition.
Embodiment two:
Commercially available low-temperature glaze is coated in them on carcasses of heavy 200 grams that mold pressing makes according to common method for coating, through 3 hours, makes the thickness of ceramic glaze layer reach 100um under 900 degrees centigrade condition.
Embodiment three:
Commercially available low-temperature glaze is coated in them on carcasses of heavy 200 grams that mold pressing makes according to common method for coating, through 3 hours, makes the thickness of ceramic glaze layer reach 100um under 1000 degrees centigrade condition.
The concentration that is placed into salinity by the sample that above-mentioned three kinds of embodiments are obtained is in 5% brine spray test machine, and under 35 ± 2 degrees centigrade temperature, through 400 hours, its corrosion resistance that detects by an unaided eye all reached good performance.
Claims (2)
1. a ceramic fishing net weighs down, and the ceramic main body is a cylinder, and the columniform hole that rope passes that holds is arranged vertically, it is characterized in that described body surfaces also has the glaze layer.
2. a kind of ceramic fishing net according to claim 1 weighs down, and the thickness that it is characterized in that described glaze layer is 10-100um.
