Delinting penetrant for cotton-seed processing

Abstract

The invention discloses a delinting penetrant for cotton-seed processing. The delinting penetrant is prepared by the following technological processes: feeding 650-750 parts by weight of polyoxyethylene ether into a reactor with mixing function, sequentially adding 240-280 parts by weight of emulsifier TS-10 (alkyl acid polyoxyethylene alkyl ether) or 6501 (coconut oil fatty acid diethanol amide)and 30-50 parts by weight of triethanolamine, and stirring for 20-60 minutes to obtain the delinting penetrant finally. The product prepared by the process disclosed by the invention does not cake incold winter, is resistant against strong acid and strong base and has fast wetting speed and stable performance, and usage amount can be greatly reduced during seed processing; meanwhile, residual acid content in the processed seeds is low, the production cost is reduced, and the product operating requirement is met.

Description

technical field [0001] The invention relates to a penetrating agent for cotton seed processing. Background technique [0002] The current cotton seed processing mainly adopts the acid delinting process, including the excessive dilute sulfuric acid delinting process and the foam acid (also called metered acid) seed delinting process. For some reason, the short wool outside the cotton wool seed is relatively dense. , Therefore, in the acid delint processing process, it is necessary to add a penetrant to the cotton wool, mainly to promote the sulfuric acid solution to quickly and evenly wet the cotton wool and react with it, so as to shorten the delint time. [0003] At present, the penetrating agent products for cotton seed delinting are various ionic surfactants and polymer compounds, such as polyoxyethylene ethers of octylphenol, nonylphenol and dodecylphenol, and there is no Considering that the climate in Xinjiang is relatively cold in winter, the products are easy to sol...

Problems solved by technology

[0003] At present, the penetrating agent products for cotton seed delinting are various ionic surfactants and polymer compounds, such as polyoxyethylene ethers of octylphenol, nonylphenol and dodecylphenol, and there is no Considering that the climate in Xinjiang is relatively cold in winter, the products are easy to solidify and have poor penetration effects under the condition of relatively low temperature. At the same time, especially in high latitude areas such as Xinjiang with abundant sunlight and large temperature difference between day and night, the cotton produced is medium Most of them have a high fat content, which further affects the penetration effect, so that the amount used in cotton seed processing is often increased to achieve the expected effect, which increases the cost of cotton seed processing
