Low-wind-resistance HEPA for dust collector

Abstract

The invention discloses a low-wind-resistance HEPA for a dust collector. The low-wind-resistance HEPA comprises two glass fiber layers and a modification fiber layer located between the two glass fiber layers. The modification fiber layer comprises, by weight, 10-100 parts of propylene-styrene-butadiene copolymer cellosilk and 10-50 parts of carbon cellosilk. Due to the fact that the structure of a common HEPA is improved, the two glass fiber layers serve as base layers, the new modification layer is arranged between the two glass fiber layers and the propylene-styrene-butadiene copolymer cellosilk and the carbon cellosilk are introduced, the filtering performance of the HEPA is improved, and the wind resistance of the HEPA is reduced; due to modification of styrene in the propylene-styrene-butadiene copolymer cellosilk, the stability of flowing of airflow in a dust collector air channel is effectively improved, the dust filtration rate of the dust collector is obviously increased, and important components in the dust collector can be protected against dust corrosion.

Description

technical field [0001] The invention relates to a filter material, in particular to a low wind resistance Hypa for a vacuum cleaner. Background technique [0002] Haipa is the transliteration of HEPA. HEPA is a kind of high-efficiency filter paper, which can filter fine particles in the air and reduce secondary pollution. As we all know, Hypa is a very important high-frequency component in vacuum cleaners. However, due to factors such as cost control, various manufacturers are slow in the development of more high-quality and efficient Hypa. However, the existing Hypa is in After using for a period of time, it is prone to clogging, resulting in poor exhaust air of the vacuum cleaner, causing the temperature of the motor to rise, which seriously affects the life of the motor; or, some dust bags have good air exhaust effect, but the filter effect on dust is not good, resulting in Under the action of strong wind, the fine dust passes through the dust bag and is discharged from ...

As we all know, Hypa is a very important high-frequency component in vacuum cleaners. However, due to factors such as cost control, various manufacturers are slow in the development of more high-quality and efficient Hypa. However, the existing Hypa is in After using for a period of time, it is prone to clogging, resulting in poor exhaust air of the vacuum cleaner, causing the temperature of the motor to rise, which seriously affects the life of the motor; or, some dust bags have good air exhaust effect, but the filter effect on dust is not good, resulting in Under the action of strong wind, the fine dust passes through the dust bag and is discharged from the vacuum cleaner, thus causing secondary pollution to the indoor environment and seriously affecting the respiratory health of the human body.

At the same time, Hypa with poor filtering effect will also affect the working environment of the motor, causing fine dust to penetrate into the motor, thus seriously affecting the normal operation of the motor
