Processing technology of adhesive tape

The invention discloses a processing technology of an adhesive tape and relates to the field of chemical technologies. The processing technology of the adhesive tape comprises processes of cutting and polishing, cleaning, fixed-length stitching, punching and preparation and smearing of a pressure-sensitive adhesive. During the fixed-length stitching process, a teflon sealing film is taken and cut into a tape which has equal width as a BOPP original tape, and the tape is placed onto a conveyor; after heated and softened at 60-68 DEG C, the tape is pressed onto the BOPP original tape at the pressure of 1-2 MPa; and BOPP original tapes are pressed at the interval of 10-15 cm on the tape-shaped teflon sealing film so as to obtain a composite film. The technology is simple. A fixed quantity of the tape can be torn. After the BOPP original tape and the sealing film are pressed together, characteristics of the BOPP transparent original tape such as good viscidity, lightness and thinness, etc. can be maintained, and the problem that an opening is not easy to find when in use and fingers easily touch glue so as to influence viscidity can be solved by the use of the sealing film. After the transparent adhesive tape is pasted, the sealing film is stretched, and on the basis of the transparent adhesive tape, the sealing film is coated. Thus, the problem that the sealing film is easy to break is solved, and sealing waterproofness of the transparent adhesive tape is also enhanced. Advantages of both the sealing film and the transparent adhesive tape are combined.

A kind of LED lamp with plug-in outlet position waterproof structure

The invention relates to an LED lamp with an inserting type wire outlet position waterproof structure. The wire outlet positions of an existing waterproof LED lamp are usually connected through screws or buckles, and therefore the waterproofness or the tensile strength is poor. The LED lamp comprises a base, a cover and an LED lamp panel, the base is provided with the wire outlet position waterproof structure with wire outlets and sliding blocks, the wire outlets and the sliding blocks are provided with upper threads and lower threads respectively, and the wire outlets and the sliding blocks are clamped tightly through the upper threads and the lower threads to form channels allowing wires to extend outwards, so that sealing and waterproofness of the wire outlet positions are achieved. Clamping parts in the original structure are formed by the sliding blocks and the wire outlets, the connecting modes between the clamping parts are changed from an original screw connecting mode and an original button stand connecting mode to an inserting connecting mode, the connecting portions of the sliding blocks and the connecting portions of the wire outlets have connecting strength and waterproof sealing performance due to the fact that the sliding blocks and the wire outlets are connected in the inserting mode, the tensile strength of the wires is guaranteed, and therefore the wires cannot be separated from the LED lamp panel even if external force is exerted on the wires.

Cable terminal tail pipe and connecting process thereof

The invention discloses a cable terminal tail pipe and a connecting process thereof. The cable terminal tail pipe comprises a conical pipe and a circular pipe; a cable connecting part connected with the metal sheath of a cable is formed at the small-caliber end of the conical pipe; the cable connecting part is cylindrical; and a spiral groove matched with the outer circumferential face of the metal sheath of the cable is formed in the inner wall of the cable connecting part. When the cable terminal tail pipe is used, the cable connecting part is in threaded connection with the metal sheath ofthe cable; and the end, far away from the conical pipe, of the cable connecting part, is fixed to the metal sheath of the cable through cold welding. With the cable terminal tail pipe and the connecting process thereof of the invention adopted, the problems of water inflow, discharge, heating and the like caused by the phenomena of de-leading, breakage, oxidation and the like easily occurring in acable terminal tail pipe and a connecting method thereof in the prior art, and the problem that cable outer shielding and even main insulation are burnt to a certain extent due to high temperature ina lead coating process in the prior art can be solved. The cable terminal tail pipe has very high practical value.
