Problems solved by technology

[0004] Therefore, the requirements for the water spray sheet are relatively high. The water spray sheet works in the cooling tower for a long time, and the requirements for temperature resistance and Vicat (heat distortion temperature) are relatively high. The pressure bearing capacity of the current ordinary water spray sheet at high temperature is very limited. , affect its life, in addition, the water shower sheet for nuclear power is located in the nuclear power plant for a long time, and the main component of the water shower sheet is PVC resin. There will be a lot of ultraviolet radiation in the work of the nuclear power plant. After a long time of ultraviolet radiation, PVC is easy to age, and The tensile strength and elongation at break will gradually decrease, which will affect the performance of the water spray sheet

Abstract

The invention discloses a water spraying sheet for high-vicat nuclear power and a manufacturing method of the water spraying sheet, and belongs to the field of the water spraying sheets. The water spraying sheet for the high-vicat nuclear power comprises the following components in parts by mass: 60-80 parts of PVC resin, 20-30 parts of chlorinated polyvinyl chloride, 3-5 parts of lead sulfate tribasic, 1-3 parts of barium stearate, 0.5-2.5 parts of inorganic filler, 0.5-2.5 parts of an ultraviolet inhibitor and 0.4-2 parts of a polymer thermal resistant modifier, wherein the inorganic filleris mica powder. The water spraying sheet provided by the invention is relatively high in vicat softening temperature, strong in tensile yield strength and UV radiation resistance, and excellent in overall performance.

Description

technical field [0001] The invention relates to the technical field of water shower sheets, in particular to a water shower sheet for high-vicat nuclear power plants and a manufacturing method thereof. Background technique [0002] With the rapid development of technology, and at the same time people's continuous demand for electricity, thermal power plants pollute the environment heavily on the one hand and waste resources, on the other hand, it is difficult to meet people's electricity needs, while nuclear power generation can generate a large amount of electricity The nuclear power plant is a new type of power plant that uses the energy stored in the nucleus to generate electricity. The nuclear power plant needs to cool down when it is working, and the cooling tower is an important part of the cooling process. [0003] As an important part of the cooling tower, the water spraying device is related to a series of issues such as the heat exchange efficiency, service life, m...
