Pewarna? Pigmen? Bagaimana membedakannya

Halo semuanya! Saya seorang karyawan bintang di CHROMÉCLAIR, sebuah merek dari merek cat kuku gel bebas hemaHari ini, kita akan membedakan antara pewarna dan pigmen dari empat perspektif.

Apa perbedaan antara pigmen dan pewarna?

Pigmen dan pewarna keduanya disebut sebagai bahan pewarna. Zat berwarna yang larut dalam air terutama digunakan untuk mewarnai sutra, wol, katun, dan bahan lainnya disebut pewarna. Kategori lainnya, yang tidak larut dalam air, terutama bergantung pada minyak atau lem untuk menempel pada permukaan bahan dan disebut pigmen, yang juga dikenal sebagai cat. Pigmen: Terutama berbasis mineral, seperti besi oksida merah, oker (oksida besi), sinabar, vermilion (merkuri sulfida), timbal merah (timbal tetroksida), dan verdigris (tembaga karbonat dasar). Pewarna: Also known as pigments. They can be natural or synthetic. Natural dyes are commonly encountered in daily life:

• Apabila makan semangka di musim panas, sari buahnya yang berwarna merah akan menodai pakaian putih dan sulit untuk dibersihkan-ini adalah jenis pewarna.

• Saat bersantap di restoran, air yang mengandung gardenia menghasilkan rona kuning tua-ini juga berfungsi sebagai pewarna kain.
• Tanaman yang dijumpai dalam kehidupan sehari-hari, termasuk bunganya, juga bisa digunakan untuk mewarnai.

Perbedaan 1: Kelarutan

Pewarna adalah zat yang mudah larut yang digunakan untuk memberikan warna pada bahan dari pelarut. Pigmen adalah zat partikulat yang tidak larut yang tersebar di dalam media yang diwarnai, menghasilkan efek hamburan. Meskipun perbedaan sederhana ini tetap valid dalam banyak kasus, namun ada banyak pengecualian, sehingga memerlukan kriteria tambahan untuk membedakan kedua pewarna ini. Tidak ada satu definisi pun yang sepenuhnya memuaskan, karena senyawa tertentu dapat diklasifikasikan sebagai pewarna atau pigmen, dan sering kali tergantung pada aplikasi yang dimaksudkan. Selama bertahun-tahun, telah umum dikatakan bahwa "pewarna larut, pigmen tidak larut.” This is generally true: Most dyes are water-soluble at some stage when applied to fibers or fabrics. However, there are exceptions, or at least borderline cases. For example, reduction dyes, such as indigo used to dye blue jeans, are typically insoluble in water but “dissolve” through reduction during the dyeing process. Unlike dyes, pigments are always insoluble in water within their application medium: any degree of solubility (termed “bleed” in the pigment industry) is considered a defect. To my knowledge, there are no exceptions. In other words, when a colorant typically used as an insoluble pigment is employed in solution, it is often simply called a dye!

Perbedaan Kedua: Organik dan Anorganik

Another traditional distinction between dyes and pigments is that dyes are organic compounds, while pigments are inorganic compounds. The number of inorganic dyes is virtually zero, but since the rise of the organic chemical industry, the number of organic pigments has steadily increased. Today, the distinction is one-sided: Most dyes remain organic, but most colored pigments are no longer inorganic. Until recently, all white pigments were inorganic—such as titanium dioxide or zinc oxide—but plastic microspheres are now being used as highly efficient, lightweight white light-scattering pigments. (e.g., water-based hollow microsphere plastic pigments, hollow microsphere white pigments)

Perbedaan Ketiga: Proses Pewarnaan

The third distinction arises from the coloring process of dyes and pigments on materials such as coatings or plastics. Coloring agents that dissolve in the medium and form transparent mixtures are called dyes, while pigments do not dissolve but scatter light, creating translucent or opaque formulations. Pigments are used when opacity is required, while dyes—typically divided into alcohol-soluble and oil-soluble types—are employed to color transparent media without compromising their transparency. Another method to achieve transparency involves using pigments with very small particle sizes or, if feasible, pigments with refractive indices similar to the medium.

Perbedaan Keempat: Mekanisme Pengikatan

The final distinction, which proves most effective and least exceptional for us, is based on the mechanism by which the colorant binds to the substrate. If the colorant exhibits affinity for the substrate (textiles, paper, etc.) and becomes an integral part of the colored material without requiring an intermediate binder, we classify this colorant as a dye. This material affinity or affinity for the substrate clearly distinguishes dyes from pigments. Pigments lack affinity for the substrate and require a binder to fix them onto the substrate. Pigments cannot adhere to surfaces without a binder. I hope this article helps you understand pigments more easily!
