Embodiment 1

[0016] First put the glass into a 400-hole crucible device, and melt the glass at 1050-1350°C by electric heating. After the glass melts, it becomes a liquid and flows down from the holes to form glass fiber filaments, which are wound on the rotating circle. At the same time, the adhesive is applied on the shaped drum. The running direction of the crucible forms a 90-degree angle with the cross-section of the drum. First, the running speed of the crucible equipment is adjusted to 6±1.2 m / min, and the linear speed of the drum is controlled at 470±50 m. / min. After 50 minutes, adjust the operating speed of the crucible equipment to 7±1.4 m / min, and control the linear speed of the drum rotation at 565±50 m / min. By adjusting the operating speed of the equipment, the glass fiber strands Form different angles to form the middle layer; after 100 minutes, adjust the running speed of the crucible equipment to 6±1.2 m / min, control the linear speed of the drum rotation at 470±50 m / min, an...

Abstract

The invention relates to a glass fibre oil fume filtering felt and a production method thereof. The glass fibre oil fume filtering felt comprises an upper layer, a middle layer, and a lower layer, wherein the upper layer and the lower layer both have the thickness of 0.5 to 2.5 millimeters and the fiber glass filament quantity of 25 to 27grams per square meter; and the middle layer has the thickness of 8 to 20 millimeters and the fiber glass filament quantity of 50 to 150 grams per square meter. The production of the glass fibre oil fume filtering felt comprises the following steps: puting glass into a crucible device to melt to form fiber glass filament; winding the fiber glass filament around a rotary barrel, applying an adhesive at the same time, and forming an angle by the operating direction of the crucible and the cross section of the barrel; and laying the fiber glass filament after the winding of the fiber glass filament is stopped and shaping by drying. The glass fibre oil fume filtering felt has relatively large dust capacity and relatively small wind pressure loss, thereby facilitating industrial production. Furthermore, the glass fibre oil fume filtering felt can be one-step arranged and formed, thereby ensuring the stability and reliability of production and reducing the production cost.

Description

technical field [0001] The invention relates to a glass fiber lampblack filter felt and a manufacturing method thereof. Background technique [0002] At present, when the household range hood is working, the oil fume is directly discharged into the air, or the filter material used cannot meet multiple requirements at the same time. The loss of wind pressure should not be large, and the filter material is also required to be waterproof, high temperature resistant and flame retardant. The material itself must be environmentally friendly, and no harmful substances can be released during use. Glass fiber itself is an inert material. Under normal conditions, its chemical and physical properties are very stable, and it can withstand high temperatures. Through our process design, the oil fume adsorption and wind pressure loss of the double-sided felt can reach one The balance point, let it meet both requirements at the same time. [0003] None of the existing domestic technologie...
