Abstract
The invention relates to a self-sinking microporous aerated pipe, which is characterized by consisting of the following components in percentage by weight: 45 to 50 percent of PVC resin, 45 to 50 percent of plasticizer, 1 to 2 percent of external lubricant, 0.3 to 0.8 percent of internal lubricant, and 1 to 3 percent of stabilizing agent. The inner diameter of the aerated pipe is 6 to 12mm; 1 to 3 rows of micropores with the diameter of 0.2 to 0.3mm are formed on the pipe wall of the aerated pipe; the distance between adjacent micropores is 0.5 to 3cm; and the arrangement direction of each row of micropores is vertical to the pipe diameter of a gas pipe. The self-sinking microporous aerated pipe has the advantages that: the aeration capacity is improved, the gas transmission length is long, the micropores are hardly blocked by impurities and infiltrated water in the pipe is easily discharged.
Description
One, technical field
The present invention relates to a kind of aeration tube, relate in particular to a kind of self-sinking microporous aerated pipe.
Two, background technology
The water body dissolved oxygen is the prerequisite that aerobic hydrobiont depends on for existence, for ensureing in the aquaculture pond water body competent dissolved oxygen is arranged, need carry out aeration oxygen replenishing to its bottom, the present micropore aeration pipe that uses need load the bob heavy mail and just can sink under water, and the micropore size of this micropore aeration pipe only is 20～30 μ m, the shortcoming that exists is a little less than the oxygen transfer rate, and the water in micropore is stopped up by impurity in the water easily and infiltration is managed from micropore can't be discharged; Simultaneously when air is imported, owing to be covered with micropore around the tube wall of this micropore aeration pipe, make blower fan be no more than 50 meters to the gas transmission length of single micropore aeration pipe, therefore need to increase an inlet mouth and blower fan every 50 meters, construction cost height thus, Operation and Maintenance complexity.
Three, summary of the invention
At above-mentioned shortcoming, the object of the present invention is to provide a kind ofly can improve that oxygen transfer rate, gas transmission length are long, micropore be difficult for being stopped up and managing by impurity in the infiltration self-sinking microporous aerated pipe of easily discharging.
Technology contents of the present invention is that a kind of self-sinking microporous aerated pipe is characterized by it and is made up of following components in weight percent
Polyvinyl chloride resin 45～50
Softening agent 45～50
Internal lubricant 0.3～0.8
Stablizer 1～3
Wherein the aeration tube internal diameter is 6～12mm; Being provided with 1～3 row's diameter on the tube wall of this aeration tube is the micropore of 0.2～0.3mm, and adjacent micropore spacing is 1.5～3cm, and the orientation of every row's micropore is vertical with the caliber of pneumatic tube.
In above-mentioned self-sinking microporous aerated pipe, polyvinyl chloride resin is polyvinyl chloride (PVC) RESINS SG-5, and softening agent is dioctyl ester DOP, and external lubricant is a polyethylene wax, and internal lubricant is a stearic acid, and stablizer is the nontoxic calcium zinc stablizer.
In above-mentioned self-sinking microporous aerated pipe, the spacing of adjacent micropore reduces along with the increase of aeration tube internal diameter.
In the present invention, self-sinking microporous aerated pipe makes by common process production, be about to extrude, to finalize the design after raw material mixes and cool off after make pipe, after punching on the pipe, promptly make the finished product self-sinking microporous aerated pipe.
The advantage that the present invention had is:
1, the density of the aeration tube made of the present invention can be drowned oneself under water in water greater than the density of water; Aperture at the tube wall of pneumatic tube is bigger, makes micropore be difficult for being stopped up by impurity in the water, and infiltration is easily discharged in the pipe.
2, the micropore that distributes on tube wall of the present invention is less, can satisfy the demand of aeration oxygen replenishing, can make again that gas transmission length increases in the pipe, can reach more than 100 meters, effectively improves dynamic efficiency, reduces blower fan quantity, saves cost.
Four, description of drawings
Fig. 1 is a structural representation of the present invention.
Five, specific embodiment
In following routine embodiment: polyvinyl chloride resin is that the Shandong letter is sent out a polyvinyl chloride (PVC) RESINS SG-5, softening agent is the dioctyl ester DOP that raises sub-petrochemical industry, external lubricant is the polyethylene wax that Jiangyin City happy magnificent plastics company limited produces, internal lubricant is the stearic acid of Japan oil and fat chemical company limited, and the nontoxic calcium zinc stablizer is the CZX-118 nontoxic calcium zinc composite thermal stabilizer of Shenzhen Sen Deli additives for plastics company limited
Example 1: 48Kg polyvinyl chloride resin, 48Kg softening agent, 1.5Kg external lubricant, 0.5Kg internal lubricant, 2Kg stablizer mixed after extrude, finalize the design, cooling and drilling technology make self-sinking microporous aerated pipe; The aeration tube internal diameter that makes is 7mm; Being provided with 1 row's diameter as shown in Figure 1 on the tube wall 2 of aeration tube 1 is the micropore 3 of 0.2mm, and adjacent micropore 3 spacings are 2cm, and the orientation of this row's micropore 3 is vertical with the caliber of pneumatic tube.
Claims (2)
