Abstract

The invention discloses a calcium-free high-purity PVC chemical tube and a production process thereof. The tube is prepared from the following raw materials in parts by weight: 100 parts of PVC resin powder, 2-6 parts of an organic tin stabilizing agent, 0.5-1.2 parts of barium stearate, 0.2-0.8 part of PE wax, 2-6 parts of chlorinated polyethylene, 2-6 parts of MBS resin, 1-4 parts of acrylate, 3-5 parts of dioctyl phthalate and 8-15 parts of activated precipitated barium sulfate. The calcium-free high-purity PVC chemical tube is prepared by kneading and extruding the above materials in parts by weight. The calcium-free high-purity PVC chemical tube is free of calcium-containing auxiliary materials, good in stability and high in cross-linking degree, and capable of remarkably improving the purity and the efficiency of extraction and purification of rare metals.

Description

A kind of without calcium high-purity PVC chemical industry tubing and production technique thereof
Technical field
The present invention relates to polymer composite, be a kind ofly specifically widely used in refining that high purity rare metal extraction tank tubing system connects without calcium high-purity PVC chemical industry tubing and production technique thereof.
Background technology
It is existing that for refining high purity rare metal, (as: purity is the yttrium oxide of 99.99%, cerium oxide, terbium sesquioxide, dysprosium oxide, Neodymium trioxide, europium sesquioxide and Erbium trioxide etc.) extraction tank usually adopt common PVC(Polyvinylchlorid, polyvinyl chloride) sheet material makes, it is all common PVC chemical industry pipe that tubing system between extraction equipment connects, common PVC chemical industry pipe have employed more light calcium carbonate, therefore when adopting this common PVC chemical industry pipe to carry out extraction process, easily in extraction solution, separate out calcium ion, the calcium concn that contains in extraction solution is caused usually to be greater than 2.0 μ g/ml, in extraction solution, calcium ion concn is too high, pole be unfavorable for DNA purity up to 99.99% the purification of rare metal.
Summary of the invention
Object of the present invention be just to provide a kind of without the need to add calcic auxiliary material, good stability, degree of crosslinking strong, can significantly improve rare metal purification by liquid extraction time purity and efficiency without calcium high-purity PVC chemical industry tubing and production technique thereof.
The present invention is made up of the raw material of following weight parts:
PVC resin powder 100, organotin stabilizer 2-6, barium stearate 0.5-1.2, PE wax 0.2-0.8, chlorinatedpolyethylene 2-6, MBS resin 2-6, CALCIUM ACRYLATE 1-4, dibutyl ester 3-5, activation process white 8-15.
A kind of production technique without calcium high-purity PVC chemical industry tubing of the present invention comprises following processing step:
A. by dosage, PVC resin powder is put in plastic hot mixing machine, then organotin stabilizer, barium stearate, chlorinatedpolyethylene, MBS resin, CALCIUM ACRYLATE and dibutyl ester is added successively, PE wax and activation process white is added again after to be mixed, high-speed kneading in plastic hot mixing machine, when mixture temperature reaches 120 DEG C, compound is dropped into cold stirring in machine to cool, be cooled to less than 60 DEG C stand-by;
B. PVC twin screw extruder is warming up to technique temperature required, fuselage sections: 180 DEG C, a district, two 175 DEG C, districts, three 172 DEG C, districts, four 170 DEG C, districts, five 165 DEG C, districts, six 170 DEG C, districts, die temperature: 180 DEG C, a district, two 182 DEG C, districts;
C. above-mentioned fully kneaded compound is dropped in PVC twin screw extruder, adopt the vacuum pressure sizing of 0.07MPa, and process by certain speed ratio, can obtain after cooling without calcium high-purity PVC chemical industry tubing.
The present invention is not owing to adopting calcic auxiliary material, therefore after employing the present invention, with support the use the concentration that greatly can reduce the calcium ion in extraction solution without the high-purity plate of calcium, test through practical application, calcium ion concn in extraction solution is less than 0.5 μ g/ml, meet the requirement that rare-earth trade refines the rare metal of high purity 99.99% completely, and efficiency when greatly can improve rare metal purification by liquid extraction.
