Application of N-Vinyl pyrrolidone

N-Vinyl pyrrolidone is achromatic bright aqueous with ablaze aldehydic smell.Mainly acclimated in authoritative hair administration gels, pharmacy disinfectant.Keep in beneath 5 °C. the monomers can be added to the UV curable blanket formulations, accumulation of adjustable and adamant artificial film. In radiation anesthetic blueprint to add NVP can advance the top ablaze and low optical blanket addendum rate, viscosity. Strengthening the achievement of products, advance abundance and abate the abuse to the ambiance pressure, is the appliance industry of drop conformal coatings application the charge to investigate the capital reason. Wooden attic industry acclimated in the ultraviolet aggressive blanket by abacus NVP can action no wax attic agnate concrete properties. Paper or paperboard acclimated in the UB and EB abating coatings, accepted requirements, low bendability and top acknowledgment activity. NVP through convalescent advancement and altitude standards and accommodated these standards, and advance acceptable abating characteristics.

N-Vinyl pyrrolidone is a achromatic to bare liquid, with a appropriate odor. It is miscible in baptize and amoebic solvents. It is the forerunner to polyvinylpyrrolidone ( PVP ), an important constructed material. The NVP monomer is frequently acclimated as a acknowledging diluent in ultraviolet and electron-beam curable polymers activated as inks, coatings or adhesives. metal UV abating coatings for accepted use of cationic vinyl ether / adhering actinic or heterocyclic arrangement composition, action of NVP and vinyl ether or acrylic anatomic crosslinking in these systems anatomy a affectionate of acceptable alive diluent. Packaging bazaar application EB and UV abating technology, to acceleration up the assembly amount and abate activity consumption. Excellent achievement and beneath odor abating press ink in awning press ink bazaar occupies an important share. Electrical accessories manufacturers to await on UV coatings accelerated processing and the action of low temperature aegis of cables and electrical apparatus and printed ambit board. Stringent discharge requirements and accept college abating rate, accomplish the automated development of a alternation of a advanced ambit of abating adhesive.

Cationic monomer properties

Cationic monomer as top purity, accumulated level, quaternary ammonium salt, top allegation body cationic monomer. The DMDAAC solution, actualization is achromatic cellophane liquid, no acerbic smell, hardly consistency. DMDAC absolutely and calmly acrid in water. Its atomic blueprint is C8H16NCl, the atomic weight of the 161.5. The atomic anatomy absolute ethylenic bifold bond, can be through a array of polymerization reaction, the accumulation of beeline homopolymers and copolymers. The characteristics of DMDAAC, at allowance temperature is actual stable, not hydrolysis, non-flammable, baby affliction to the skin, low toxicity. The artefact has two kinds: one absolute a baptize band-aid of a assertive concentration; a solid white powder. This artefact is agreeable 65% and 60% aqueous solution, two specifications. In 200 liter polyethylene artificial brazier or polyethylene artificial lined galvanized adamant drums of 200 kgs net each. Due to ablaze ( UV ) or top temperature will could cause the artefact to polymerize, therefore, appropriate accumulator should abstain light, at the aforementioned time accumulator temperature should not beat 30℃.

Cationic monomer as a cationic monomer polymer or copolymer are formed through the polymer. The polymer, in bolt dyeing and finishing auxiliaries can be acclimated as accomplished non-formaldehyde acclimation agent, in the bolt on the film, advance the dyeing fastness; in papermaking additives can be acclimated as assimilation and arising agent, cardboard blanket antistatic; in the action of baptize analysis can be acclimated for the decolorization, flocculation and purification, top able and nontoxic; in circadian actinic industry, can be acclimated in absterge carding agent, wetting abettor and antistatic agent; in oilfield chemicals, can be acclimated as flocculant, baptize active agent. Its capital role is to allegation neutralization, adsorption, flocculation, purification, decolorization, abnormally as a constructed adhesive modifier, able with conductive, antistatic. It is one of the a lot of important cationic monomer, can homopolymerization copolymerization with added monomers, such as acrylamide, methacrylamide, acrylonitrile, methyl acrylate, methyl methacrylate, styrene, acrylic acerbic or methacrylic acid, the polymer into a quaternary ammonium group, and can be broadly acclimated for bearing flocculant, antistatic coatings, cardboard additives, oilfield chemicals, cilia additives such as accomplished polymer products.
