Abstract

The invention discloses a powder alkali cleaner, comprising the following substances of: 25-35 wt% of grape alkali, 54-69 wt% of sodium hydroxide, 2-12 wt% of tetrasodium edetate, and 0-2 wt% of soda ash. The powder alkali cleaner provided by the invention is applicable to clean spinning spinnerets (PACK), parts and monomer candles of chemical fiber and terylene factories; can remove carbide, heat scale, dirt, grease stain and polymer, resist rust, and strip titanium dioxide (TiO2) on filter tubes; by using the powder alkali cleaner, two third of additive volume can be saved, the waste processing amount can also be reduced, the filter changing period of filter cores can be prolonged, the production process can be improved, and the output and quality can be greatly enhanced.

Description

technical field [0001] The invention relates to a special powdery cleaning agent, which is especially suitable for cleaning a polymerization filter element (candle) and a spinning spinneret (PACK) in a chemical fiber polyester factory. Background technique [0002] At present, when domestic and foreign cleaning agents are used in chemical fiber polyester factories to clean the polymerization unit filter element, it is difficult to remove the titanium dioxide (TiO2) on the filter tube with a fineness of 10μ. 2 ) stripping, resulting in a short filter cycle and high replacement frequency, which greatly affects the production of chemical fibers; and the general use of cleaning agents is large, and the amount of wastewater is also large, causing troubles in sewage treatment. [0003] In addition, China's chemical fiber industry is currently actively working towards the development of fine fiber denier products. The finer the fiber, the higher the quality requirements; The filte...
