1、 The main content of silicon defoamer formula in agricultural production system: 10% methylsilane oil, 10% sodium tripolyphosphate, 70% salt, 5% mannitol, 2% silicon dioxide 。 stay Silicon defoamer for agricultural production system Dimethyl silicone oil plays a role in defoaming. Usually, silicon dioxide (i.e. white carbon black )The main function of white carbon black is to help dimethyl silicone oil disperse in the foam end and improve the defoaming speed. 2、 Preparation method: At room temperature, first mix the methyl siloxane oil and silicon dioxide, then add the mixed sodium tripolyphosphate, mannitol, salt, etc., and fully mix them to obtain the silica defoamer for the agricultural production system of white powder products. Production of silicon defoamer emulsion for agricultural production system: add defoamer for white powder finished products cooled to a certain temperature Emulsifier And co emulsifier and fully stir them, and then pour the mixture into deionized water at a certain temperature (add slowly while stirring, so as to obtain silicon defoamer emulsion of agricultural production system with stable performance). 3、 The following matters should be paid attention to when using defoamer in agricultural production system: The emulsion shall be fully stirred before use or sampling. www.tjyfhkj.cn www.tjyfhkj.com www.zgyfhkj.cn Second, although the oil in water emulsion can be diluted at will, the stability of the emulsion will also decline sharply, such as stratification, so please add water to the defoamer and slowly stir when diluting. Better join Thickening agent To improve its stability. Third, because the emulsion is stable at the original concentration, the diluted emulsion must be used up in a short time. Fourth, prevent frost! Emulsion is sensitive to frost and temperature higher than 40 ° C, and easy to be damaged. If the frozen emulsion can be carefully defrosted, it must be tested before further use. Fifth, long-time strong oscillation or shearing (such as using mechanical pumps, homogenizers, etc.) or mixing will destroy the stability of the emulsion. http://zzt20120304.chemcp.com Sixth, if you want to improve the stability of the emulsion, you can add thickening agent to improve the viscosity of the emulsion. http://zzt20120304.goepe.com/ http://zjl542374980.net114.com http://com.fayifa.com/542374980/ http://www.zzt20120304.eb80.com/ http://zzt20120304.b2b.youboy.com/ http://zzt20120304.b2b.huangye88.com/http://yunhunjituan.chinawj.com.cn/ http://yunhui888.cn.china.cn/ http://zzt20120304.bmlink.com/ http://490974319.cn.makepolo.com/ http://zzt20120304.net114.com/ http://china.herostart.com/company/zzt20120304 http://zzt20120304.b2b.hc360.com http://www.zzt2012030.icoc.cc/ http://zzt20120304.cn.gongchang.com http://www.yunfanhui888.eb80.com/ http://zzt20120304.com.pe168.com/ http://yunfanhui.cn.gongchang.com http://zzt20120304.chinawj.com.cn http://zzt20120304.cn.made-in-china.com/ http://zzt20120304.cnbaowen.net/ http://zzt20120304.cn.nowec.com/ http://zzt20120304.qjy168.com/ http://zzt20120304.51sole.com/ http://zzt20120304.cn.b2b168.com/ http://zzt20120304.cn.coovee.net/ http://www.zzt20120304.jc85.com/ http://zzt20120304.jdol.com.cn/ http://b2b.wubaiyi.com/com/zzt20120304/ Yunhui Yunfanhui Chemical Building Materials Factory sincerely welcomes you to call us to research and manufacture various special-shaped sealing materials zzt20120304.b58b.com Thermal insulation and fireproof materials and water treatment * * agent flocculant sewage desilter * * bacteria agent fireproof insulation board coating foam glass plate pipe, removable Thermal clothing, Insulation sleeve , thermal insulation cover, energy-saving thermal insulation clothing, detachable valve thermal insulation clothing cover, low price, considerate service |
