Surface - active agent that this kind of product uses , for instance : gather ethylene glycol , ren base phenol and gather oxygen and ethylene ether , gather the amine salt in alcohol ether , polyvinyl alcohol , alkyl sulphonate , season etc .

2 ) the shape and average size of the nanometer caco3 particles have been tested through tem . 3 . on the basis of hlb suitable surface - active agents such as polyether , tween - 60 , span - 20 and span - 80 , which exist as capsules , are selected

Surface - active agent these play carrier and help function that dissolve in bending over in iodine , complexing ability of them it helps to be very much ideal to dissolve result , these kind of iodine there are quite a few of " existence forms of iodine " that do not possess the sterilization activation but waste of bending over , can leave yellow to dye even burn the skin at skin also at the same time
16.
Moreover , because there are many kinds of surface - active agents , there are many kinds of prescription and making technology , therefore , it is various in style that the iodine produced is bent over , the iodine with the document report bends over more than 100 kinds , in market not of our country sell iodine bend over because too it more than 10 kinds , like gathering there aren t ethylene glycol the iodines , ren base phenol , the iodine can only exist to bend over with the liquid state , the stability is bad , the sterilization level is low , the poisonous side effect is different , have been eliminated for a long time in the western developed country

By adopting x - ray diffraction and transmission electron microscope ( tem ) , this thesis has insepectd the size and the structure of the calcium carbonate ( caco3 ) particles . according to hydrophile and lipophile balance ( hlb ) , the suitable surface - active agents have been selected and put into lubricating oil with nanometer caco3 particles
18.
Meanwhile , fundamental principles about electroless tin plating by reducing agent and disproportionation reaction were explained . function of every component in the bath was explained that complexing agent can effectively change the potential of copper and tin , and accelerate the beginning of replacement reaction favorably ; reducing agent can increase the rate of chemical reaction and has the effect of promoting reaction dynamics too ; antioxidant can effectively prevent sn2 + in the bath from being oxidated ; additive agent a can improve the stability of the bath ; additive agent b has such effects as refining and brightening for the tin deposits , and it enlarges the range of brightening section ; additive agent c used as leveling agent can not only make the depostis level off , but also improve the dispersive ability of the bath ; surface - active agent can solve bubble problem which gathered on the surface of the deposits , and improve the surface quality of the deposits and the bath stability

Henan road technologies limited is a pure chemical production of fine chemicals mainly to study the high - tech enterprises , is the production of carbon jimiji surface - active agents , and conventional carbon surface active agent than its spot , more pro - oil base , a number of lower - level critical jiaoshu concentrations may increase as the number of levels of reactive surface in the extremely low concentrations of an outstanding performance , and some anions and surface active agent hunrong without precipitation

The law of dispersion behavior of diamond and carborundum in medium of water was studied . the influence of the ph , dispersants and surface - active agent on the dispersion behavior of particles was researched . by calculation of potential energy the essence of dispersion behavior of particles in water was analyzed
