Problems solved by technology

[0003] At present, expanded perlite is useful for washing daily chemical products, but industrial-grade expanded perlite has large particles, rough surface, weak adsorption, and insufficient whiteness. Especially when used as a raw material for hand sanitizer, it is not easy to rub and easily hurt the skin. , and the oil absorption ability is not strong, the cleaning ability is not enough

Embodiment Construction

[0019] The present invention will be further elaborated below in conjunction with specific examples.

[0020] The processing method of perlite for cleaning of the present invention, concrete following steps:

[0021] Step S1: screening raw ore, selecting components by mass percentage including 68%-70% of silicon dioxide, 12.5-15% of aluminum oxide, 1-1.5% of iron oxide, 3.5%-4% of sodium oxide, calcium oxide 0.5-2%, 3-3.5% potassium oxide, 0.1%-0.4% manganese oxide, 4-6% water, and other components of perlite ore as raw materials, screened out perlite ore suitable for particle size grade as raw material, using Raw sand with a particle size of 0.15-0.2mm.

[0022] Step S2: Gas preheating, put the qualified perlite into the preheating furnace through the funnel, burn and heat with gas, so that the temperature in the preheating furnace cavity reaches the required preheating temperature, the preheating temperature is 320°C, preheating stay for 24 minutes;

[0023] Step S3: Comb...

Abstract

The invention discloses a processing method for cleaning perlite. The processing method comprises the following steps: weighing raw materials consisting of, by mass, 68 to 70% of silica, 12.5 to 15% of alumina, 1 to 1.5% of iron oxide, 3.5 to 4% of sodium oxide, 0.5 to 2% of calcium oxide, 3 to 3.5% of potassium oxide, 0.1 to 0.4% of manganese oxide and 4 to 6% of water, with the balance being perlite ore sand; preheating and retaining the raw materials in a preheating furnace with a temperature of 300 to 350 DEG C for 20 to 25 min; then adding the preheated raw materials into an expansion generation furnace and carrying out contact combustion at a temperature of 950 to 1000 DEG C; and carrying out retention for 1 to 5 s after occurrence of expansion so as to prepare the cleaning perlite. The cleaning perlite prepared in the invention has a whiteness as high as more than 98, uniform particle sizes, an average particle size of 1 mm and a porous microstructure, is light, loose and soft, can be crushed by slight pressing of fingers, shows water and oil absorbing ability and good cleaning effect and can be widely used as a raw material for daily washing chemicals like a liquid soap or a hand cleaner.

Description

technical field [0001] The invention relates to the technical field of expanded perlite, in particular to a processing method of perlite for cleaning and perlite for cleaning. Background technique [0002] Perlite is an acidic siliceous volcanic glass rock containing crystal water formed by volcanic action, which belongs to igneous rock; because there are pearl-like cracks in the rock section, it is called perlite in magma. Its micro-powder material is roasted at high temperature to form a lightweight thermal insulation granular material with closed and open pores, which is called expanded perlite. Expanded perlite is a lightweight, versatile new material. It has the characteristics of light apparent density, low thermal conductivity, good chemical stability, wide temperature range, low moisture absorption capacity, non-toxic, odorless, fireproof, sound absorption, etc., and is widely used in various industrial sectors. [0003] At present, expanded perlite is useful for w...
