Embodiment Construction

[0030] use figure 1 process and figure 2 A glyphosate potassium salt preparation produced by advanced equipment, the raw materials include solid-phase glyphosate with a moisture content of 9%-10%, alkaline salt or alkali containing potassium ions at a concentration of 45%-49%, And the weight ratio of the two is 1:1.05-1.1, and it also contains tallow amine surfactant accounting for 9%-10% of the total weight and cocamide synergist accounting for 3%-4% of the total weight.

[0031] During production, the glyphosate mother liquor is first dehydrated by using a horizontal scraper centrifuge. The speed of the horizontal scraper centrifuge is about 800-850 rpm, with intermittent start and stop, and the start and stop cycle is about 2-3 minutes; the liquid phase The pipe diameter of the outlet is about 100mm, and the diameter of the outlet for solid-phase glyphosate is about 450mm.

[0032]Then adopt spiral mixer to mix materials, described spiral mixer, by cylinder body 1, stirr...

Abstract

The invention provides a glyphosate potassium salt preparation, which comprises the following compositions: solid glyphosate with moisture rate of 6%-12%, 40%-48% alkaline salt or alkaline solution containing potassium ions, 8%-12% of tallow amine surfactant, and 2-5% of cocamidopropyl synergist, and other filling agents. For the forming equipment, firstly a horizontal scraper centrifugal machine is started on or off intermittently, then the glyphosate potassium salt preparation is mixed and prepared in a spiral mixer with the heating temperature of 55-65DEG C. the mutual penetrating performance of all compositions can be increased according to the proportion of the used surfactant, synergist and raw materials, the cloud points of the preparation can be increased, the hydrophilicity is increased, and the adaptability of environment temperature can be increased; in addition, no emission of three wastes during production and forming do not exist.

Description

technical field [0001] The invention relates to the formulation, process and forming device of glyphosate potassium salt in the field of agrochemical industry. Background technique [0002] Glyphosate is a commonly used pesticide, and other salts can be used to synthesize glyphosate ammonium salt, glyphosate potassium salt, glyphosate isopropoxide, glyphosate ammonium sulfate, etc. [0003] The invention of application number 998107301 provides a glyphosate concentrate formulation preferably containing more than 400 g / l expressed as glyphosate acid, comprising glyphosate potassium salt, alkyl glycoside surfactant and alkoxylated Alkylamine surfactants wherein the preferred total concentration of alkylglycoside and alkoxylated alkylamine is about 160 to 300 g / l, the preferred ratio of alkylglycoside to alkoxylated alkylamine per 1 part by weight From about 1 part by weight of alkoxylated alkylamine to about 1 part by weight of alkylglycoside to about 5 parts by weight of alk...
