Abstract
The invention discloses a method for preparing enamel glass glaze with high anticorrosion performance for glyphosate production equipment. The method comprises the following steps of: preparing all raw materials, melting for 4 hours at the temperature of 1,350+/-20 DEG C to obtain molten liquid, quenching in water, air-drying for 4 hours in a hot air drying oven at the temperature of 90 DEG C to obtain a lump material, drying the prepared lump material, ball-milling by adding a certain amount of mill addition to obtain glaze slurry, coating the glaze slurry on an iron green body, sintering at the temperature of 880 DEG C, and keeping the temperature for a quarter of an hour. The method has the advantages that: various properties of the prepared porcelain glaze for the equipment are greatly improved, and the porcelain glaze is particularly suitable for production process reactions with strong chemical corrosion, high temperature and strong mechanical shock such as glyphosate and the like. The porcelain glaze greatly improves the stability and prolongs service life of chemical glass-lined equipment; and the overall performance of the chemical glass-lined equipment using the porcelain glaze approaches or reaches the international advanced level.
Description
Technical field
The present invention relates to a kind of glaze formulation and preparation method thereof, relate in particular to a kind of prescription and preparation method thereof of strong antiseptic property enamel of glyphosate production equipment.
Background technology
Chemical reaction kettle uses enamel for glassed steel to be air retaining wall, is the traditional technology of reaction apparatus always.But enamel for glassed steel commonly used, often can only be acidproof, or can only be alkaline-resisting etc. function, and when reaction under intensively stirred shearing force impact condition; When violent difference variation situation was perhaps arranged, the glaze layer of equipment liner very easily came off, on the one hand because overhaul of the equipments cause produce influenced; The opposing party's cover-coat enamel pull-up falls, and makes the equipment corrosion situation aggravate, thereby reduces the working life of equipment; Conventional chemical plant enamel for glassed steel sintering time is longer; Most about 15 hours, in the preparation process, energy consumption was higher.
Summary of the invention
The object of the present invention is to provide a kind of prescription and preparation method thereof of strong antiseptic property enamel of glyphosate production equipment; This glaze layer has performances such as anti-strong acid, anti-highly basic, anti-violent mechanical stirring shearing force impact, the sudden turn of events of temperature resistance difference; Make the performance of each side can both have an isostatic to embody; The minimizing client is the cycle of exchange device more, has improved production efficiency.

Its preparation method is: after above-mentioned all raw materials are prepared; In 1350 ± 20 ℃ of temperature environments, found became melt liquid in four hours after, earlier through shrend, then in 90 ℃ of hot air driers after air-dry four hours the piece material; With the piece material elder generation ball milling after super-dry that makes; Will add following mill addition at mechanical milling process, mill addition and piece material mass ratio are following, are 1 in piece material weight: clay 5%, wilkinite 0.5%, sodium silicofluoride 0.5% and water 50%; Obtain glaze slip behind the ball milling, be coated on the iron embryo after, behind 880 ℃ of firing process, the insulation qr, get final product.
(0.4-0.6MPa) atomisation forms one deck coating to the glaze slip that defibrination of the present invention obtains on the iron embryo of glyphosate production equipment through high-pressure air;
Technique effect of the present invention is: the enamel each item performance on the equipment that makes improves greatly, is particularly suitable for production technique such as the Glyphosate 62 IPA Salt reaction of extensive chemical burn into high-temperature, strong physical shock.This kind enamel has improved the stability and the life-span of chemical glass lining device greatly, its overall performance of chemical glass lining device that uses this kind enamel near or reached international most advanced level.
