Abstract

The invention discloses a soak solution for cleaning screws of a plastic extruder, and relates to the technical field of machining device cleaning. The soak solution is prepared from, by weight, 90-100 parts of calcined diatomite, 12-16 parts of nanometer aluminium oxide, 50-60 parts of tea seed powder, 25-30 parts of orange leaf powder, 20-25 parts of coconut powder, 12-18 parts of hydroxyethyl cellulose, 12-16 parts of straw ash, 10-15 parts of glycine betaine, 10-15 parts of antirust additives, 7-12 parts of sodium n-alkyl benzene sulfonate, 7-12 parts of citric acid, 6-10 parts of sucrose ester, 6-10 parts of triolein, 5-8 parts of sodium chloride, 30-35 parts of glycol ether and 200-250 parts of diesel oil. With calcined diatomite as the main raw material and modified through nanometer aluminium oxide and with tea seed powder, orange leaf powder and the like as auxiliaries, the prepared soak solution is good in cleaning effect, short in preparation time, and easy to remove.

Description

Technical field: [0001] The invention relates to the technical field of processing equipment cleaning, in particular to a soaking liquid for cleaning the screw of a plastic extruder. Background technique: [0002] Extruders for processing plastic products often need to produce products in different colors according to customer requirements. Before changing the color of the produced product, the screw of the screw extruder must be cleaned to prevent the residual color of the previous batch of products on the screw from affecting the color of the subsequent product. The usual cleaning methods are: (1) After heating a large amount of raw materials to be produced, continuously extrude the last batch of residual materials in the screw until the color of the extruded plastic is the same as the color of the product to be produced. This cleaning method not only Waste of raw materials and time, and high energy consumption; (2) use screw cleaners containing cleaning resin, such as pa...
