Embodiment
[0031] 1. Preparation of bamboo charcoal fiber
[0032] Carbonization: First, heat the bamboo to 450-550°C at a heating rate of 5°C / min for low-temperature carbonization. After low-temperature carbonization for 30 minutes, heat the carbonized product after low-temperature carbonization to 800-1100°C at a heating rate of 5°C / min. Carry out high-temperature carbonization, and obtain the final carbonized product after high-temperature carbonization for 90 minutes;
[0033] Activation: Put the above-mentioned charcoal into the atomization equipment for spray activation, atomize into a transient spray, and the charcoal is rapidly cooled and extinguished to produce a complex porous structure to complete the activation of the charcoal;
[0034] Pulping: Grinding the activated bamboo charcoal to make sub-nanometer bamboo charcoal powder, mixing the bamboo charcoal powder into the raw pulp of polyester or viscose, and stirring to make it evenly dispersed in the raw pulp.
[0035] Fila...

Abstract
The invention belongs to the technical field of bathroom hoses, and relates to a preparation method of a bamboo carbon fiber reinforced PVC hose. The method comprises the steps that bamboo carbon fiber is knitted into a net through a net knitting machine on a production line, and the bamboo carbon fiber net and polyvinyl chloride resin are compositely extruded through an extruder to form the bamboo carbon fiber reinforced PVC hose of a three-layer structure, wherein the bamboo carbon fiber reinforced PVC hose sequentially comprises a PVC inner layer, a bamboo carbon fiber middle layer and a PVC outer layer from inside to outside, and the bamboo carbon fiber is prepared through the steps of low-temperature carbonization, high-temperature carbonization, spray activation, pulping, shredding and the like of bamboo wood. The hose prepared through the preparation method of the bamboo carbon fiber reinforced PVC hose is not knitted from metal, has good mechanical property and heat resistance,and can meet the use requirements of bathroom cold and hot water pipes.
Description
technical field [0001] The invention belongs to the technical field of sanitary hoses and relates to a preparation method of bamboo carbon fiber reinforced PVC hoses. Background technique [0002] The sanitary hoses in the prior art are generally divided into two types, one is a cold water hose, and the other is a general purpose hose for hot and cold water. Among them, most of the cold water hoses have three layers, the inner polyvinyl chloride (hereinafter referred to as PVC) layer, the middle 1000D network cable reinforcement layer, and the outer PVC layer. The general hose for hot and cold water has four layers, the inner PVC layer, the middle 1000D polyester network cable reinforcement layer, the outer PVC layer, and the outer steel wire braided reinforcement layer. [0003] The disadvantages of this hot and cold water pipe are: complicated process, low production efficiency of steel wire weaving, high cost of steel wire, and easy wire leakage of joint installation ste...
