Abstract
The invention discloses a preparation method of a high-quality permeation tube, and belongs to pipelines of irrigation facility in agricultural production. The high-quality permeation tube comprises the following components: 40-mesh tread powder, 60-mesh tread powder, low-density polyethylene (LDPE 4314), common LDPE, high-density polyethylene (HDPE), PE modifier, external lubricating agent, internal lubricating agent and azodicarbonamide (AC). The preparation method of the high-quality permeation tube comprises the steps of: adding the above raw materials to a mixer according to a weight ratio, sufficiently stirring at the temperature raising from normal temperature to 70 DEG C, and taking out a mixed material; placing the mixed material in a plastic extruder, and extruding and shaping; and cutting the extruded pipelines according to specification requirement, and processing and boring side holes according to preset requirement. Because the high-quality permeation tube effectively overcomes the defects of high aging speed, short life, poor blast prevention capability, nonuniform water inflow and outflow, easy breakage and the like, the investment cost of the pipelines of the irrigation facility in agricultural production is reduced, and the popularization of water-saving drip irrigation technique in agricultural science is promoted.
Description
Technical field
The present invention relates to the pipeline of irrigating facility in the agriculture production, especially relate to a kind of droping irrigating pipe of agricultural sciences water saving, specifically a kind of preparation method of high-quality permeation tube.
Background technology
Drip irrigation is to have certain pressure water, evenly and lentamente water is splashed near the soil plant root by filtering by tubing system by the permeation tube of terminal, implements the purpose of localized irrigation.Drip irrigation has water-saving, it is even, energy-conservation to irrigate, strong adaptability, volume increase, the saving of labor of soil and landform, make things convenient for the advantage such as farm work.Yet the drip irrigation facility investment is higher, stops up easily in the work, and is therefore higher to water quality requirement.Drip irrigation is applicable to the area that the cash crop such as fruit tree, vegetables, flowers, warmhouse booth and water source extremely lack, the irrigation of high-lift draw water irrigated area and topographic relief larger area, and also there is certain development prospect in sandy soil and salt water area strong to water-permeable, poor water retention property simultaneously.
The existing prescription of making permeation tube and preparation method mainly are again by the extrusion machinery shaping after adopting plastics and tyre surface powder commonly used etc. to mix.Its quality is made us carrying on a shoulder pole outstanding, and especially aging speed is exceedingly fast, the problems such as anti-explosion ability of life-span short (generally can only use about 1 year), Inlet and outlet water are inhomogeneous, frangibility.Also so virtually increased the cost of the investment of drip irrigation.
Summary of the invention
In order to overcome the shortcomings such as existing permeation tube aging speed is fast, the objective of the invention is to provide a kind of prescription simply, the preparation method of the reliable and stable a kind of high-quality permeation tube that is shaped.
The technical solution adopted for the present invention to solve the technical problems is: a kind of component of high-quality permeation tube and weight ratio:
40 purpose tyre surface powder 25KG account for 39.6%,
60 purpose tyre surface powder 12.5KG account for 19.7%,
LDPE (4314) 10KG accounts for 15.8% (LDPE is polyethylene),
Common LDPE 10KG accounts for 15.8%,
HDPE (6001) 3KG accounts for 4.7%,
PE modification agent 1.5KG accounts for 2.4%,
Outer lubrication prescription 0.5KG accounts for 0.8%,
Interior lubrication prescription 0.5KG accounts for 0.8%,
AC 0.03KG accounts for 0.47% (AC whipping agent).
A kind of preparation method of permeation tube
(1) put mixer into after the raw material of above nine kinds of components is weighed by weight and fully stir, the stirring of mixer hold in both hands rotating speed be 1400 minutes/turn, the temperature of stirring rises to 70 ℃ from normal temperature, namely can take out compound.
(2) compound that takes out is put into plastics extruder and carry out extrusion molding, the speed of extrusion molding is 8～9 meters on per minute clock, and per pass length and the temperature of forcing machine in moulding process is respectively: the 1st road length is 0.48 meter, and temperature is 150 ℃; The 2nd road length is 0.48 meter, and temperature is 150 ℃; The 3rd road length is 0.48 meter, and temperature is 160 ℃; The 4th road length is 0.48 meter, and temperature is 165 ℃; The 5th road length is 0.48 meter, and temperature is 170 ℃.
(3) block by specification requirement and extrude pipeline, and carry out the side opening Drilling operation by the requirement of drafting.
The invention has the beneficial effects as follows: because deficiencies such as the present invention has overcome effectively that aging speed is fast, the life-span is short, anti-explosion ability, Inlet and outlet water are inhomogeneous, frangibility, can reduce the pipeline investment cost of irrigating facility in the agriculture production, be conducive to promote popularizing of agricultural sciences water-saving drip irrigation technology.
