Pigmentová fialová 23-Corimax fialová RLS

Pigment violet 23 is an organic compound that is a commercial pigment. It is member of the dioxazine family of heterocyclic compounds, but derived from carbazoles. It is prepared by condensation of chloranil and 3-amino-N-ethylcarbazole. It has a centrosymmetric angular structure. For many years, the structure was assigned, incorrectly, as having a "linear structure" (EC no. 228-767-9, CAS RN 6358-30-1) which differ in terms of the carbazole ring fusion.

Pigment violet 23 is prepared by condensation of an aniline with chloranil.[From Wiki]

Zeyachem is a global supplier of Dioxazine Violet pigments that provide a bluish violet shade, a color not obtainable by other pigments.

The extremely high color strength of Pigment violet 23 makes it a suitable pigment as a shading component. PV23 also exhibits excellent heat fastness and light fastness properties, making it suitable for inks and many paints and coatings applications.

Corimax Violet RLS is a reddish blue shade Dioxazine Violet (PV23) pigment with very high color strength and excellent overall fastness properties, suitable for inks, paints and coatings, including industrial coatings, powder coatings and automotive coatings.

Vlastnosti:

low viscosity, high gloss, high color strength. Pigment Violet 23 is a transparent purple violet pigment with high saturation and tinting strength.

C.I.Pigment Violet 23 show good tinting strength in flexible PVC while poor resistance to immigration.

P.V.23 heat resistance above 230℃ in polyolefins, when used in transparent PS, temperature shall below 220℃, above this PV 23 shall decompose. When worked in polyester, it is 280℃ stable in 5 hours, while concentration shall above 0.05%.

The pigment is easy to use and requires no rinsing. To ensure maximum color intensity and proper adhesion to the pulp, a retention agent must be added to the pulp before the pigment is applied. Our pigments are supplied by volume sizes. The actual weight varies, depending upon the density of the pigment.

použitie:

Odporúčané pre automobilové farby, architektonické farby, zvitky, priemyselné farby, práškové farby, tlačiarenské pasty, PVC, guma, PS, PP, PE, PU, ofsetové farby, atramenty na vodnej báze, atramenty na báze rozpúšťadla, UV atramenty.

Pigment Violet 23 (PV 23) has now been around for more than 55 years. Its beginnings go back to 1928, when a patent was filed for the pigment after researchers at the Hoechst company in Germany first undertook the multistage synthesis based on carbazole, an ingredient of coaltar, and chloranile. Until the end of World War II the pigment was only used to process diamine light blue, a direct dyestuff for cotton.

With the invention of reactive dyes, which considerably simplified the dyeing and printing process for cellulose fibers, this application lost its importance. A new and promising use for PV 23 was quickly found due to the pigment’s ability to produce unique colors.

PV 23 has been used as a pigment since 1953. PV 23 belongs to the group of high-performance polycyclic pigments (HPP’s) that are used whenever the requirements for a colorant are particularly high. These include high light fastness and weather fastness, fastness to solvents, and heat stability. In addition, PV 23 stands out by its high coloring power. Under the electron microscope, the crude violet shows a highly granular crystalline form, whereas the pigment particles are miniscule.

Použitie produktu:Pigmentová fialová 23 sa používa hlavne na farbenie náterov, tlačiarenských farieb, gumy a plastov a tiež na farbenie syntetických vlákien.
Existuje 124 druhov komerčných formulácií pigmentu. Karbazoazín je druh modrej fialovej odrody so silnou a nezvyčajnou aplikáciou a špecifický povrch monolitovej fialovej RN je 74 m2 / g. To je široko používaný v rôznych oblastiach, ako je povlak, atramentová tlač, plast a tlač tkanín a farbenie. Pri vyfarbovaní má dobrú stálosť. Môže sa používať na sušenie vzduchom, automobilových farieb OEM a farieb na pečenie, najmä na latexové farby s tonerom CuPc a silným svetlým odtieňom. Môže sa použiť na farbenie plastov s tepelnou odolnosťou 280 ℃ v polyolefíne a vysokou retenciou farieb (pre HDPE s 1 / 3SD je potrebné iba 0,07% koncentrácie pigmentu); môže sa tiež použiť na farbenie polyesteru a PE.

Princíp syntézy: Karbazol sa používa ako surovina a N-etylácia sa uskutočňuje za normálneho tlaku v prítomnosti katalyzátora fázovej inverzie a nitračná reakcia a redukčná reakcia sa uskutočňujú na syntézu 2-amino-N-etylkarbazolu; 3,5,6-tetrachlórparaquinón (chloranil) sa podrobí kondenzačným reakciám a reakciám s uzavretím kruhu, filtruje sa, premyje sa vodou a suší sa, čím sa získa surová karbazolová violeť; nakoniec, všeobecné ošetrenie pigmentáciou miesením alebo miesením, čím sa získa CI pigmentová fialová 23.
