Quick answer:<\/strong> For fluorescent-whitening and food-contact discussions, buyers usually focus on specification fit, migration risk, regulatory boundaries, and how the additive behaves in the finished plastic system rather than treating it as a simple color question.<\/p>\n\n\n\n

1. Pencerah optik OB dan Pencerah optik OB-1 adalah bahan kimia yang sama sekali berbeda<\/strong><\/h3>\n\n\n\n\n

2. Pencerah optik OB<\/a> dan Pencerah optik OB-1<\/a>keduanya terlihat seperti saudara. Ketika banyak orang mendengar Optical brightener OB dan Optical brightener OB-1 untuk pertama kalinya, mereka menerima begitu saja bahwa Optical brightener OB-1 adalah kompleks ob. Dengan produk ini, kemurnian ob dikurangi satu menjadi Optical brightener OB-1. Jadi, apa perbedaan antara Optical brightener OB dan Optical brightener OB-1, produk apa yang harus menggunakan Optical brightener OB, dan produk apa yang lebih cocok untuk optical brightener OB-1.<\/h4>\n\n\n\n

Nama kimia: Pencerah optik OB-1<\/h4>\n\n\n\n

Nama lain Pencerah Fluoresen 393; 4,4\u2032-Bis (2-benzoxazolyl) stilbene; Pencerah Fluoresen OB-1<\/h4>\n\n\n\n

Nomor CAS: 1533-45-5<\/h4>\n\n\n\n

Rumus molekul: C28H18N2O2<\/h4>\n\n\n\n

Berat molekul: 414,45<\/h4>\n\n\n\n

Pencerah optik OB-1 cocok untuk memutihkan serat kimia seperti serat poliester, serat nilon, dan serat polipropilena. Mencerahkan dan mencerahkan plastik polipropilena, PVC kaku, ABS, EVA, polistirena, polikarbonat, dll. Ini ditambahkan dalam polimerisasi konvensional poliester dan nilon.<\/h4>\n\n\n\n

Untuk mencapai pemutihan plastik yang seragam dengan sifat yang berbeda-beda, zat pemutih fluoresen tidak hanya harus beradaptasi dengan kondisi pemrosesan plastik, tetapi juga harus memiliki dispersi molekuler yang cukup atau kelarutan yang sempurna di dalam plastik. Pada plastik, efek pencerahan optik tidak dapat ditampilkan atau sangat berkurang. Pemilihan model yang tepat dari bahan yang berbeda, akan sangat meningkatkan efek pencerahan zat pemutih fluoresen.<\/h4>\n\n\n\n

3. Rumus molekul Optical brightener OB adalah C26H26N2O2S, dan rumus molekul Optical brightener OB-1 adalah C28H18N2O2. Dari gambar di atas, kita bisa melihat secara jelas bahwa keduanya adalah bahan kimia yang sama sekali berbeda.<\/h4>\n\n\n\n

<\/p>\n\n\n\n

Produk apa yang menggunakan Optical brightener OB, produk mana yang lebih cocok untuk Optical brightener OB-1?<\/strong><\/h3>\n\n\n\n

<\/p>\n\n\n\n

Walaupun keduanya merupakan dua zat kimia yang berbeda, namun dari penamaannya, Anda juga bisa menebak, bahwa ada banyak kesamaan di antara keduanya. Contohnya, Optical brightener OB dan Optical brightener OB-1 memiliki berbagai macam aplikasi. Sebagian besar OB plastik dan Optical brightener OB-1 dapat digunakan secara umum, dan efek pemutihan serta pencerahannya terlihat jelas. Jadi, di manakah letak perbedaannya?<\/h4>\n\n\n\n

<\/p>\n\n\n\n

1. Titik leleh: Pencerah optik OB-1> Pencerah optik OB<\/h3>\n\n\n\n

<\/p>\n\n\n\n

Karena titik leleh pencerah optik OB adalah 200 derajat, dan titik leleh pencerah optik OB-1 setinggi 360 derajat, hal ini menentukan bahwa pencerah optik OB tidak dapat digunakan untuk produk plastik bersuhu tinggi, seperti selubung AC dan beberapa peralatan dapur. Oleh karena itu, jika produk Anda memerlukan pemrosesan suhu tinggi, pencerah optik OB-1 adalah pilihan pertama Anda.<\/h4>\n\n\n\n

<\/p>\n\n\n\n

2. Dispersi dan stabilitas: Pencerah optik OB> Pencerah optik OB-1<\/h3>\n\n\n\n

<\/p>\n\n\n\n

Di sini, pertama-tama kami harus menjelaskan bahwa dispersibilitas yang baik berarti produk lebih mudah larut dan merata. Misalnya, cat dan tinta memiliki persyaratan yang tinggi pada daya sebar zat pemutih fluoresen; stabilitas yang baik berarti bahwa produk tidak mudah berpindah tempat dan menguning pada tahap selanjutnya. Misalnya, beberapa sol sepatu yang lebih rendah berwarna putih dan bersih saat pertama kali dibeli, tetapi menguning dan berubah warna setelah beberapa saat, yang menunjukkan bahwa stabilitas zat pemutih fluoresen buruk.<\/h4>\n\n\n\n

<\/p>\n\n\n\n

Tentu saja, saya tidak mengatakan bahwa dispersi dan stabilitas pencerah optik OB-1 tidak bagus, tetapi sedikit lebih buruk daripada ob. Karena perbedaan ini, Lianda Fluorescence Technology umumnya tidak merekomendasikan penggunaan pencerah optik OB-1 pada lapisan tinta dan plastik lunak. Ob relatif lebih baik dalam hal dispersibilitas dan ketahanan cuaca, dan tidak mudah menguning. Situasi migrasi.<\/h4>\n\n\n\n

<\/p>\n\n\n\n

Harga adalah perbedaan terbesar antara Pencerah optik<\/strong><\/strong> ob dan Pencerah optik OB-1<\/strong><\/h3>\n\n\n\n

<\/p>\n\n\n\n

Sebenarnya, perbedaan terbesar antara Optical brightener OB dan Optical brightener OB-1 adalah harganya. Saya ingat bahwa 6 tahun yang lalu, harga Optical brightener OB mirip dengan Optical brightener OB-1. Namun, karena perbaikan perlindungan lingkungan nasional China, pasokan bahan baku OB pencerah optik mengalami masalah, sehingga harga OB pencerah optik meroket. Pencerah optik OB lebih dari dua kali lebih mahal dari pencerah optik OB-1. Menurut perkiraan departemen R&D Longchang Chemical, itu mungkin meningkat. Karena perbedaan harga yang sangat besar, pelanggan yang dapat menggunakan pencerah optik Pencerah optik OB-1 harus mencoba memilih Pencerah optik OB-1. Mereka yang memiliki persyaratan khusus, seperti pelapis tinta kelas atas dan plastik lunak, disarankan untuk menggunakan pencerah optik OB.<\/h4>\n\n\n\n

<\/p>\n\n\n\n

Menghadapi melonjaknya harga OB pencerah Optik, departemen R&D Longchang Chemical terus berinovasi dan mengembangkan pencerah khusus yang cocok untuk berbagai produk untuk menggantikan OB pencerah Optik, mengurangi biaya bagi pelanggan, seperti ld- untuk masterbatch warna.s01, ld-y01 untuk pelapis tinta berbasis minyak khusus, dll.

How buyers usually evaluate specialty additives in compliance-sensitive plastics<\/h2>\n

Food-contact and compliance-sensitive additive projects usually need a tighter screen than general industrial formulations. The strongest path usually combines specification review, migration thinking, and validation in the real polymer system.<\/p>\n

    \n
  • Start from the regulatory boundary:<\/strong> customer and market requirements often decide the screening route before formulation optimization begins.<\/li>\n
  • Check the polymer and processing route:<\/strong> the same additive can behave differently across resin systems, temperatures, and contact conditions.<\/li>\n
  • Review appearance together with compliance:<\/strong> visual performance still needs to be balanced against safety and documentation needs.<\/li>\n<\/ul>\n

    FAQ for buyers and formulators<\/h3>\n

    Why do compliance-sensitive plastic additives need more than a basic specification check?<\/strong>
    Because end-use exposure, migration limits, and customer requirements can change whether an additive is commercially acceptable.<\/p>\n

    Is visual effect enough to justify additive selection in food-contact plastics?<\/strong>
    Usually no. Appearance needs to be reviewed together with processing, documentation, and compliance fit.<\/p>\n","protected":false},"excerpt":{"rendered":"
