Example Embodiment

[0008] Examples:

[0009] Fix the straightened 32-152m bristles in a round tower-shaped metal cylinder. After soaking with white water, drain the remaining water into a pressure-resistant and temperature-resistant metal container, close the container lid, and open the opening for steam pressure and heating , Gauge pressure 0-6kg / cm 2 , Thermometer at room temperature -160℃, after holding pressure for 0-4 hours, close the open steam, open the closed steam heating, gauge pressure 0-6kg / cm 2 , Thermometer at room temperature -160℃, keep pressure for 0-4 hours, and turn on the vacuum pump for suction at the same time, control the vacuum state until the container and the moisture of the bristles meet the production requirements of the next process, the moisture should be controlled at 8-15% , Turn off the closed steam, turn off the vacuum pump to open the container cover without negative pressure in the container, take out the metal cylinder, and remove the metal cylinder to obtain the...

Abstract

The high pressure, high temperature and vacuum bristle straightening and drying process includes water soaking, high temperature and high pressure straightening, vacuum drying and other steps. It features that the vacuum pump is used to make negative pressure state inside the container, so as to make water inside the connector and in bristle gasified and exhausted to atmosphere. The technological process is simple, convenient, low in water, power and gas consumption, short, high in product quality and environment friendly.

Description

Technical field: [0001] The invention is a method for straightening and drying pig bristles in high-pressure, high-temperature vacuum, which is composed of high-pressure, high-temperature, straightening, vacuum, drying and other processes of pig bristles. Production of high-quality brush bristles of various types. Background technique: [0002] The pig bristles currently used as raw materials in the brush industry must be straightened before they can be used. The modern traditional process is: 1. Boil in normal pressure boiling water until the straightening is qualified → enter the drying room and dry until the next process. The production requirements are 2. High pressure and high temperature water boiling and straightening → drying in the drying room until the production requirements of the next process shall prevail. The process method is expensive, time-consuming, and has a long production cycle; it consumes more water, electricity, coal, and steam, and the product qual...
