Embodiment Construction

[0013] The antibacterial kitchen and bathroom pipe is composed of three layers, the outer layer is a polypropylene layer, the middle layer is a reinforcement layer, and the inner layer is an antibacterial layer. The production process steps are:

[0014] A. Three-layer co-extrusion: After the three-layer raw materials are sent to the outer layer extruder, the middle layer extruder and the inner layer extruder for mixing, they are co-extruded at one time; When starting up and heating up, set the temperature in stages for 3 times, heat for a stable period, and then proceed to the next period; the first heating is 1 hour, the outer layer extruder, the middle layer extruder and the inner layer extruder 1 zone The temperature is 75-85°C, the temperature in zone 2-5 is 100-120°C, the temperature in zone 1 of the co-extrusion machine is 75-85°C, the temperature in zone 2-3 is 100-120°C, the temperature in zone 1-5 of the mold is 100-120°C; Heating for 1 hour, the temperature of the o...

Abstract

An antibacterial kitchen and bathroom pipe and its production process. The antibacterial kitchen and bathroom pipe is composed of three layers. The outer layer is a polypropylene layer, the middle layer is a reinforcement layer, and the inner layer is an antibacterial layer. The production process steps are: A. Three layers Co-extrusion: The three-layer raw materials are sent to the outer layer extruder, the middle layer extruder and the inner layer extruder respectively, and after mixing, they are co-extruded at one time; Three stages of temperature setting, heating for a stable stage, and then proceeding to the next stage, B. Shaping water cooling: the above-mentioned one-time co-extruded pipe is shaped by a pipe vacuum shaping machine, and the vacuum degree of the pipe vacuum shaping machine is controlled at -0.35—5MPa ; Then enter the vacuum water cooling box for cooling. Advantages: 1. The antibacterial layer contains silver-loaded zirconium phosphate as a non-eluting antibacterial agent, and the antibacterial effect is durable, high temperature resistant, and stable. 2. The quality is good and strong, the appearance is beautiful, the inner and outer walls of the pipe are smooth, no scale, and the heat resistance is more excellent.

Description

technical field [0001] The invention relates to a kitchen and bathroom pipe and a production process. Background technique [0002] Some of the kitchen and bathroom pipe products produced by the existing antibacterial kitchen and bathroom pipe production technology are not good enough, and some do not have antibacterial function. Contents of the invention [0003] The purpose of the present invention is to provide a production process for antibacterial kitchen and bathroom pipes in view of the lack of good product quality and no antibacterial function of the kitchen and bathroom pipes produced by the existing antibacterial kitchen and bathroom pipe production process. [0004] The antibacterial kitchen and bathroom pipe is composed of three layers, the outer layer is a polypropylene layer, the middle layer is a reinforcement layer, and the inner layer is an antibacterial layer. [0005] Its production process steps are: [0006] Three-layer co-extrusion: The three-layer ...
