Problems solved by technology

Most of the domestic spinning equipment only measures and controls the ambient temperature of spinning, and occasionally performs simple manual intervention on the humidity, such as adding desiccant, dehumidifier, etc., based on this method to spray electrospun fibers Simple and arbitrary control of ambient temperature and humidity lacks operational reliability and stability of environmental parameters, which is extremely unfavorable for high-quality production or research of electrospun fibers
A small number of high-end electrospinning fiber equipment in foreign countries has installed special temperature and humidity control devices in the spray environment, but the equipment structure is complex and expensive, which is not conducive to large-scale promotion and use in China

Abstract

The invention relates to an electrospinning fiber injection device with the controllable injection environment and a control method of the injection environment, belonging to the field of electrostatic spinning. In order to realize thermostatic control over temperature and humidity of electrostatic spinning and make a spinning space compact and adjustable, the technical key points are described inthat an air-blowing tank is composed of four rectangular support racks; the four rectangular support racks form integrated or detachable connection through a mode of connecting left with right side walls; the upper side wall of each rectangular support rack communicates with the air-blowing tank; the inner side wall and the outer side wall are enclosed walls; then a transverse air-blowing openingis formed in at least one inner side wall of the four rectangular support racks; the lower side wall is equipped with an air-blowing opening, through which an air curtain is sent; and a transverse air-blowing opening is formed in the inner side wall of one rectangular support of the air-blowing tank.

Description

technical field [0001] The invention belongs to the field of electrospinning, and relates to a device for controlling constant temperature and humidity of an electrospinning injection environment. Background technique [0002] Electrospinning technology is widely used in the field of nanofiber material preparation. Due to its excellent physical and chemical properties, nanofiber materials have a wide range of application fields and unlimited development prospects. Countries are stepping up to improve the existing electrospinning technology or develop new electrospinning equipment. In the process of electrospinning, the charged polymer solution is sprayed, stretched, split, volatilized and solidified in a high-voltage electrostatic field to finally form fibrous properties. There are many parameters that affect the morphology and properties of electrospun fibers, such as the voltage provided by the high-voltage power supply, the distance between the collecting plate and the s...
