[0003] However, since the 1980s, it has been found that asbestos fibers can penetrate into the human respiratory tract and deposit down, thereby causing various respiratory diseases, even lung cancer and malignant mesothelioma. It is a high carcinogen, and asbestos in almost all commodities has Carcinogenicity

specific Embodiment approach 1

[0022] Specific Embodiment 1: The asbestos-free, environmentally friendly and energy-saving diaphragm cloth of this embodiment is woven from one, two or three of polyether ketone ether fibers, polyphenylene sulfide fibers, and polypropylene fibers, and Diaphragm cloth that meets the following conditions: (1) unit weight: 0.5-1.5kg / square meter; (2) cloth thickness range: 0.5-1.5mm; (3) warp and weft density: warp 100-280 / 10cm, weft 56- 150 pieces / 10cm; (4) Alkali loss: no more than 2%; (5) Airtight performance No air bubbles are allowed within 2 minutes under the pressure of 300 mm water column.

specific Embodiment approach 2

[0023] Embodiment 2: This embodiment differs from Embodiment 1 in that when polyether ketone ether fiber and polyphenylene sulfide fiber are used as raw materials, the mass percentage of the two is 30-70:30-70.

specific Embodiment approach 3

[0024] Embodiment 3: This embodiment is different from Embodiment 1 in that when polyphenylene sulfide fibers and polypropylene fibers are used as raw materials, the mass percentage of the two is 70-95:5-30.

Abstract

The invention provides asbestos free environment protective and energy-saving type diaphragm cloth and the weaving method, which relates to diaphragm material and the weaving method. The diaphragm cloth of the invention adopts one, two or three component(s) from the polyether ketone ether fiber, the polyphenyl thioether fiber, and the polypropylene fiber, and meets the following requirements: unit weight: 0.5 to 1.5 kg / square meter; cloth thickness range: 0.5 to 1.5 mm; gauge of cloth: longitude 100 to 280 piece / 10 cm, latitude 56 to 150 piece / 10 cm; alkali loss: no larger than 2 percent; airtight protection performance: no air bubble produced in two minutes under the pressure of 300 mm water column, and the weaving can be performed according to the wool spinning technology and the cotton spinning technology. The invention breaks the trade barrier of the developed countries, the overall level of the hydrogen making and oxygen making equipment of our country is enhanced, and the pollution to the environment and the harm to the human body by the asbestos dust are reduced. Compared with the traditional asbestos diaphragm cloth, the thickness of the production can be reduced as low as 55 to 85 percent, and more than 10 percent of the energy can be conserved.

Description

technical field [0001] The invention relates to a diaphragm material and a weaving method thereof, in particular to an asbestos-free diaphragm cloth and a weaving method thereof. Background technique [0002] Since Austria used compressed asbestos as the diaphragm material base material in 1860, it has a history of more than 100 years. Asbestos has been widely used in many fields due to its low price, excellent temperature resistance, alkali resistance, high strength, and good operating performance. At present, asbestos diaphragm cloth is used as the diaphragm material in the water electrolysis hydrogen production and oxygen production equipment in my country. [0003] However, since the 1980s, it has been found that asbestos fibers can penetrate into the human respiratory tract and deposit down, thereby causing various respiratory diseases, even lung cancer and malignant mesothelioma. It is a high carcinogen, and asbestos in almost all commodities has Carcinogenicity. Beca...
