Using a uv masterbatch with these additives keeps colors bright and materials strong. <\/p>\n<h3>\u65e0\u673a\u7d2b\u5916\u7ebf\u5438\u6536\u5242<\/h3>\n<p> Inorganic uv absorbers use minerals like titanium dioxide, zinc oxide, and cerium oxide. These additives scatter and reflect uv rays instead of soaking them up. They work well in coatings, films, and paints. The table below compares some inorganic uv absorbers: Carbon black is another strong uv absorber. It soaks up uv, visible, and infrared light. This makes it useful in many products. Adding these minerals to a uv masterbatch gives strong protection for outdoor items. <\/p>\n<h3>\u5e38\u89c1\u7528\u9014\u548c\u5e94\u7528<\/h3>\n<p> \u8fd9\u4e24\u79cd\u7c7b\u578b\u7684\u7d2b\u5916\u7ebf\u5438\u6536\u5668\u5728\u8bb8\u591a\u884c\u4e1a\u90fd\u6709\u5e94\u7528\u3002\u4ee5\u4e0b\u662f\u4e00\u4e9b\u5e38\u89c1\u7528\u9014\uff1a <\/p>\n<ul>\n<li>\u6c7d\u8f66\u4fdd\u62a4\u6c7d\u8f66\u90e8\u4ef6\u4e0d\u892a\u8272\u3002<\/li>\n<li>\u7ed3\u6784\u4f7f\u5efa\u7b51\u6750\u6599\u4fdd\u6301\u575a\u56fa\u548c\u8272\u5f69\u9c9c\u8273\u3002<\/li>\n<li>\u5305\u88c5\uff1a\u5e2e\u52a9\u98df\u54c1\u548c\u8d27\u7269\u514d\u53d7\u7d2b\u5916\u7ebf\u7684\u4f24\u5bb3\u3002<\/li>\n<li>\u4e2a\u4eba\u62a4\u7406\uff1a\u4fdd\u62a4\u76ae\u80a4\u548c\u5934\u53d1\u514d\u53d7\u7d2b\u5916\u7ebf\u4f24\u5bb3\u3002<\/li>\n<li>\u519c\u4e1a\uff1a\u7528\u4e8e\u519c\u4e1a\u7eba\u7ec7\u54c1\uff0c\u4fdd\u62a4\u519c\u4f5c\u7269\u3002<\/li>\n<li>\u6d82\u6599\u548c\u7c98\u5408\u5242\uff1a\u4f7f\u7269\u54c1\u66f4\u6301\u4e45\u3001\u66f4\u7f8e\u89c2\u3002<\/li>\n<\/ul>\n<p> \u4f60\u7ecf\u5e38\u4f1a\u53d1\u73b0\u4e00\u4e2a <a href=\"https:\/\/changhongchemical.com\/product\/\" target=\"_blank\" rel=\"noopener\">UV \u6bcd\u7c92<\/a> \u5728\u5851\u6599\u3001\u8584\u819c\u548c\u7ea4\u7ef4\u4e2d\u4f7f\u7528\u3002\u8fd9\u79cd\u6dfb\u52a0\u5242\u6709\u52a9\u4e8e\u963b\u6b62\u7d2b\u5916\u7ebf\u964d\u89e3\uff0c\u4f7f\u4ea7\u54c1\u7115\u7136\u4e00\u65b0\u3002\u4e86\u89e3\u7d2b\u5916\u7ebf\u5438\u6536\u5242\u7684\u7528\u9014\u6709\u52a9\u4e8e\u60a8\u9009\u62e9\u6700\u9002\u5408\u81ea\u5df1\u9700\u8981\u7684\u7c7b\u578b\u3002 <\/p>\n<h2>\u7d2b\u5916\u7ebf\u5438\u6536\u5242\u4e0e\u7d2b\u5916\u7ebf\u7a33\u5b9a\u5242\u7684\u6bd4\u8f83<\/h2>\n<h3>\u4e3b\u8981\u533a\u522b<\/h3>\n<p> \u60a8\u53ef\u80fd\u4f1a\u8ba4\u4e3a <a href=\"https:\/\/changhongchemical.com\/product\/lcsorb-uv-3035-cas-5232-99-5\/\" target=\"_blank\" rel=\"noopener\">\u7d2b\u5916\u7ebf\u5438\u6536\u5668<\/a> \u548c\u7d2b\u5916\u7ebf\u7a33\u5b9a\u5242\u662f\u4e00\u6837\u7684\u3002\u5b83\u4eec\u90fd\u80fd\u4fdd\u62a4\u805a\u5408\u7269\u5236\u6210\u7684\u7269\u54c1\uff0c\u4f46\u4f5c\u7528\u4e0d\u540c\u3002\u7d2b\u5916\u7ebf\u5438\u6536\u5242\u7684\u4f5c\u7528\u5c31\u50cf\u4e3a\u4f60\u7684\u7269\u54c1\u63d0\u4f9b\u4fdd\u62a4\u3002\u5b83\u5438\u6536\u7d2b\u5916\u7ebf\u5e76\u5c06\u5176\u8f6c\u5316\u4e3a\u70ed\u91cf\u3002\u8fd9\u6837\u5c31\u80fd\u9632\u6b62\u7d2b\u5916\u7ebf\u4f24\u5bb3\u6750\u6599\u5e76\u5bfc\u81f4\u7d2b\u5916\u7ebf\u964d\u89e3\u3002 <a href=\"https:\/\/changhongchemical.com\/product\/uv-5151-cas-104810-48-2\/\" target=\"_blank\" rel=\"noopener\">\u7d2b\u5916\u7ebf\u7a33\u5b9a\u5242<\/a> do something else. They help after uv light has already started to harm the material. These additives stop bad chemical reactions by blocking free radicals. This helps keep the material strong even after some uv exposure. Here is a table that shows how they are different: <\/p>\n<h3>\u4f55\u65f6\u4f7f\u7528<\/h3>\n<p> Pick the right additive for what you need to protect. If you want to keep clear things from turning yellow, use uv absorbers. They help coatings and films stay new-looking. If you want to stop cracks or fading in plastics, use a uv stabilizer for plastics. Uv stabilizers for plastics help things stay strong and bendy, even after lots of sun. Use uv stabilizers for colored or thick items. These work deep inside the product. Uv stabilizer for plastics is used in outdoor chairs, car parts, and playground toys. For the best results, use both uv absorbers and uv stabilizers together. This gives your things the most protection from the sun. <\/p>\n<h2>\u9009\u62e9\u5408\u9002\u7684\u7d2b\u5916\u7ebf\u5438\u6536\u5668<\/h2>\n<h3>\u9009\u62e9\u56e0\u7d20<\/h3>\n<p> \u5f53\u4f60 <a href=\"https:\/\/changhongchemical.com\/uv-absorber-360-really-works-for-you%EF%BC%9F\/\" target=\"_blank\" rel=\"noopener\">\u9009\u62e9\u7d2b\u5916\u7ebf\u5438\u6536\u5668<\/a>, you need to think about a few things.

Outdoor furniture and car parts need different uv protection. The table below shows what to look for: You should also think about the weather. Humidity and heat can change how well uv absorbers work. Lots of moisture and high heat can make uv damage happen faster. So, you need an additive that can handle these things.

First, check what kind and how much uv your product will get. Next, see if your material already resists uv. Think about how long you want your product to last outside.

UV stabilizers help make this possible. When you add a uv absorber to plastic or coatings, it gives strong protection from sunlight. Studies show plastics with uv absorbers stay strong and keep out water, even after bad weather. For example, treated films can keep a high contact angle of 145\u00b0 after being outside. This means they stay tough and do not break down fast.
