The invention discloses a production technology and a device of improving fastness of an ink jetted code on a PP-R pipeline. According to the technology, the surface of the pipeline is coated with a water-proof bottom layer before code ink jetting of the pipeline; the water-proof bottom layer increases surface free energy of the PP-R pipeline and a bonding force between ink and the pipeline; the jetted code fastness of the ink jetted code on the PP-R pipeline is improved. According to the technology, the surface of the pipeline is coated with the water-proof bottom layer by a circular arc sponge head; the water-proof bottom layer comprises a base material, a waterproofing agent, a curing agent, a surfactant, an adhesive and an environment-friendly plasticizer that are in defined parts; the molecular polarity of the surface of the PP-R pipeline can be improved effectively; the adhesion between the ink and the PP-R pipeline is increased, so that the jetted code fastness is improved; the appearance of the obtained PP-R pipeline is identical with that of the original pipeline; the jetted code fastness is improved by 3 times or above; the technology is simple to operate and easy to achieve, and has no influence on a production speed; the surface of the obtained PP-R pipeline is not damaged; long-term heat resistance pressure of a product is effectively ensured; the product can be used for 50 years or more.

The invention discloses a production process of high-precision circular weft machine accessories, comprising the following steps: processing an inner needle cylinder blank and a plurality of outer needle cylinder blanks that can be fixed and covered on the outer side wall of the inner needle cylinder blank; A threaded hole is processed on the inner side wall of the inner cylinder blank, and a connecting hole corresponding to the threaded hole is processed in the inner syringe blank; the outer syringe blank is fixed; the outer wall of the outer syringe blank is processed until the outer wall of the outer syringe blank The needle groove is full; multiple processed outer needle cylinder blanks and inner needle cylinder blanks are fixedly connected together to form a needle cylinder; the needle cylinder processed by this process, when the needle groove on the outer surface of the needle cylinder is damaged during the working process , the outer needle cylinder blank can be replaced according to the damaged area, and the entire needle cylinder does not need to be scrapped, which is more environmentally friendly and reliable; during processing, the entire needle cylinder will not be scrapped because of an error in the processing of a certain needle groove, which will cause the processing failure of the entire needle cylinder, High processing error tolerance.

The invention discloses a method for removing pollutant granules in a barrier layer and a metal layer, comprising the following steps: etching a metal layer and a barrier layer which are doped with pollutant granules by a dry etching technique and etching to the surface of a dielectric layer; and milling and removing the partial thick dielectric layer by a chemical mechanical polishing process. By employing the method, the production cost of a semiconductor apparatus can be lowered.
