What are the types of chemical additives?

Feb 24, 2016

  Chemical additives are used as a chemical additive in a certain industry.It's a wide variety,it generally consists of a metal processing additives, additives for plastics, papermaking additives, building auxiliaries, water treatment chemicals, coating auxiliaries, leather auxiliaries, electronic industrial auxiliaries, textile auxiliaries, wood additives.

   What are the types of chemical additives?

   Metal processing aids can be divided into:Anti rust lubricant, metal cleaning agent, drawing liquid, press liquid, cutting fluid, electroplating additives, metal craft liquid, etc.

   Plastic additives can be roughly divided into:

Plastic brightener, plastic deodorant, foaming agent, antifogging agent, antioxidant, release agent。

   Papermaking additives can be divided into:

Four types of chemicals used in pulp and paper making, paper making, coating auxiliaries and paper two.

   Coating additives can be divided into:

Bright agent, dispersing agent, conductive agent, curing agent, driers, toughening agent, emulsifier, thickening agent, defoaming agent, leveling agent, anti skinning agent, flatting agent, light stabilizer, anti mildew agent, antistatic agent etc.

   Textile printing and dyeing auxiliaries are generally divided into:

Thickener, adhesive, crosslinking agent, emulsifier, dispersant and other printing auxiliaries, etc.

   Wood additives can be roughly divided into:

Wood preservative, wood waterproof agent, wood preservatives, bleaching agent, flame retardant wood, wood softener etc.
   1. General complexing agent 1) features: it is used for and is coordinated to the metal ions, complexation, the complexation process is reversible; 2) use: sustained release agent, corrosion inhibitor, scale inhibitor, masking agent and so on; 3) products: tartaric acid, citric acid, gluconic acid, alginic acid and its sodium salt, trimerization of phosphate, pyrophosphate, metaphosphate, amino trimethylene phosphonic acid and its sodium salt, N - (2-hydroxyethyl) iminodiacetic acid, iminodiacetic acid, ammonia triacetic acid NTA, EDTA and sodium, polyacrylate, polystyrene sulfonic acid and its sodium salt, and so on.

   2. Strong complexing agent (chelating agent) 1) features: to and is coordinated to the metal ions, chelation chelation is the most complex, poor reversibility; 2) use: sustained release agent, corrosion inhibitor, scale inhibitor, softening agent, flocculant and so on; 3) products: nitrilotriacetic acid nitrilotriacetic acid (NTA), ethylenediamine tetra Ethyl Acid, EDTA and sodium, ethylene diamine tetramethylidene phosphoric acid sodium edtmps, diethylene triamine penta fork, phosphonate detpmp, amino trimethylene phosphate, phytic acid and so on
