Hydroxyethyl cellulose using method Hec is a type of white or mild yellow, odorless, non-poisonous fibrous or powdered solid, h2o soluble non-ionic cellulose ether. Can be broadly employed in polypropylene, and polystyrene suspension method, emulsion and acrylate new latex paint, colorful coating, ion trade resin, day-to-day chemical compounds, oil field drilling, building materials, textile printing and dyeing, papermaking machinery processing and other departments. Hydroxyethyl cellulose, as a kind of nonionic surfactant, aside from thickening, suspension, glue, floating, into a film, colloid, water retention, and supply protection function 1. Directly when grinding paint to join: this method is the most straightforward, and the time is short. In depth measures are as follows: (1) in the high correct purified water should be additional to lower mixer drum (usually, ethylene glycol, wetting agents and movie previous and so on to be part of at this time) and (two) start to stir consistently at reduced velocity and slowly include hydroxyethyl cellulose (3) continue to stir until all moist particles (4) insert fungicide, PH regulator, and so on. (five) stir right up until entirely dissolved all hydroxyethyl cellulose (resolution viscosity elevated considerably) to be part of other parts in the system, grinding into paint. 2. Matched with into gruel phenology: as the organic solvent that is negative for hydroxyethyl cellulose solvent, as a result can be outfitted with porridge by organic and natural solvent. The most commonly used natural and organic solvents this sort of as ethylene glycol, propylene glycol, and film former (this kind of as glycol and diethylene glycol butyl acetate), drinking water is also toxic solvent, Food Additives Were Demonized in China water is utilized jointly with natural liquid, used for outfitted with porridge. The evolution of hydroxyethyl cellulose can be straight extra to paint. When the gruel hydroxyethyl cellulose has totally been sacks. When included paint, then instantly dissolve, and thickening influence. Be part of right after nonetheless have to keep on to stir until finally totally dissolved hydroxyethyl cellulose, uniform so significantly. Standard porridge disc is created of 6 natural solvent or water combined with a hydroxyethyl cellulose, about five-30 minutes, hydroxyethyl cellulose hydrolysis and obviously risen. General drinking water during the summer time humidity is way too large, must not be utilized for geared up with porridge. three. Equipped with mom liquor with Hudson: this method is equipped with a high concentration of mother liquor very first, then add to the latex paint, the method has the advantage of higher versatility, can be right added to paint in the completed merchandise, but should be appropriately stored. Phase and strategy with strategy one in action (one) - (4) are equivalent, the difference is require higher must minimize mixer, only some electricity adequate to keep hydroxyethyl fibers evenly dispersed in aqueous answer of mixed with can. Keep on to stir until finally entirely dissolved into a viscous solution. Need to pay out consideration to is: the mould must be as shortly as attainable to be part of in the mother liquor.
