Cleaning agent for screw extruder and preparation method thereof

Abstract

The invention provides a cleaning agent for a screw extruder. The cleaning agent is characterized in that the cleaning agent mainly containing an inorganic mineral micro fiber powder body comprises the following ingredients in parts by weight: 50-60 parts of micro fiber powder body, 20-30 parts of inorganic adsorbent, 5-10 parts of activator, 3-5 parts of lubricant and 1-2 parts of dispersant. The invention further provides a preparation method of the cleaning agent for the screw extruder; the method comprises the following steps of micro-dispersing the micro fiber powder body by a vertical jet micro-pulverizer and activating and modifying the by using the activator to obtain a micro fiber brush; and the method is characterized in that the micro fiber brush obtained due to the activation and the modification by using the activator can promote the activator to permeate into the stubborn carbon deposit and dust deposit so as to activate the carbon deposit and the dust deposit, and the inorganic absorbent slightly expands to absorb various activated granular impurities and rapidly remove the impurities out of the screw by adhesion. The cleaning agent has the characteristics of good cleaning effect, high cleaning speed, and no new resin residues, can be applied to the cleaning of the screw extruders in the industries of plastic, rubber, food and the like, and is especially suitable for the cleaning of various types of resin.

Description

technical field [0001] The invention belongs to the field of cleaning agents, and relates to a granular solid cleaning agent, in particular to a solid granular cleaning agent specially used for cleaning screw extruders and a preparation method thereof. Background technique [0002] Screw extruder is a high-efficiency continuous production equipment commonly used in plastics, rubber, and food processing industries. Since the screw machine usually needs refueling, color changing, shutdown, maintenance, etc., it is inevitable to leave materials in the dead angles and gaps between the screw thread and the barrel. On the one hand, the leftover materials are easy to carbonize and stick to the screw and are difficult to remove. Long-term carbonization, fouling, and material accumulation will cause impurities to enter the product from time to time, seriously affecting precision production and product quality; Productivity. [0003] In order to quickly clean the screw extruder, Chi...

Problems solved by technology

[0005] The present invention aims at the defects of incomplete cleaning of carbon deposits, poor adaptability and high cost of current screw cleaning agents, and proposes a screw extruder cleaning agent with inorganic mineral microfiber powder as the main material. The screw cleaning agent is The microfiber powder is dispersed and activated and modified with the activator to form a microfiber brush, and the activated agent is activated and modified to form a microfiber brush to promote the penetration of the active agent into the stubborn carbon deposit and scaling, thereby activating the carbon deposit and scaling, and using The micro-expansion adsorption of the inorganic adsorbent quickly adheres various activated granular impurities out of the screw, cleans thoroughly, fast, and does not leave new resin. It is suitable for the cleaning of screw extruders in plastics, rubber, food and other industries. Especially suitable for cleaning various types of resins
