Cette propri\u00e9t\u00e9 est tr\u00e8s importante pour les syst\u00e8mes de polyester insatur\u00e9 et les syst\u00e8mes de s\u00e9chage UV compos\u00e9s de monom\u00e8res multifonctionnels. Dans ces syst\u00e8mes chimiques complexes, le photo-initiateur 1173 agit comme un conducteur \u00e9l\u00e9gant, dirigeant m\u00e9thodiquement la r\u00e9action de durcissement. Il a non seulement l'avantage d'\u00eatre peu odorant, \u00e9vitant ainsi l'odeur piquante d\u00e9sagr\u00e9able lors de l'utilisation, mais il est aussi parfaitement performant en termes de stabilit\u00e9 de la couleur. Cette stabilit\u00e9 de la couleur est comme un gardien loyal qui prot\u00e8ge le royaume de la couleur, permettant au produit durci de conserver longtemps sa couleur d'origine sans le probl\u00e8me g\u00eanant du jaunissement. Il convient \u00e9galement de mentionner qu'il pr\u00e9sente une excellente compatibilit\u00e9 et qu'il peut \u00eatre facilement compos\u00e9 avec d'autres photo-initiateurs, comme des pi\u00e8ces de puzzle qui s'assemblent pour obtenir un effet plus important.<\/p>\n<p>Dans le vaste domaine des applications pratiques, le photo-initiateur 1173 s'est r\u00e9v\u00e9l\u00e9 extr\u00eamement polyvalent. Prenons l'exemple des syst\u00e8mes de vernis acryliques photopolym\u00e9risables. Ils peuvent \u00eatre utilis\u00e9s sur tous les supports, des produits en bois d\u00e9licats aux \u00e9quipements m\u00e9talliques robustes, en passant par le papier ordinaire et divers types de plastique. Si l'on observe l'\u00e9volution de l'industrie du meuble au fil des ans, on constate qu'au d\u00e9but, avant l'av\u00e8nement de ce photo-initiateur tr\u00e8s efficace, il fallait souvent beaucoup de temps pour durcir la laque sur les surfaces en bois, et la finition \u00e9tait sujette \u00e0 des d\u00e9colorations et \u00e0 d'autres probl\u00e8mes. L'arriv\u00e9e du photo-initiateur 1173 a \u00e9t\u00e9 comme l'injection d'un puissant stimulant cardiaque dans l'industrie, am\u00e9liorant consid\u00e9rablement l'efficacit\u00e9 de la production et la qualit\u00e9 des produits.<\/p>\n<p>Dans l'industrie moderne, les rev\u00eatements plastiques UV, les rev\u00eatements bois UV, les encres papier UV et d'autres domaines sont ins\u00e9parables de la pr\u00e9sence du photo-initiateur 1173. Il est comme un h\u00e9ros dans les coulisses de ces domaines, conduisant tranquillement le d\u00e9veloppement de l'industrie. Les \u00e9tudes de march\u00e9 montrent que les produits utilisant le photo-initiateur 1173 se sont consid\u00e9rablement am\u00e9lior\u00e9s en termes de stabilit\u00e9 de la qualit\u00e9 et d'acceptation par le march\u00e9. Cela n'est pas seulement d\u00fb \u00e0 ses excellentes performances, mais aussi au fait qu'il s'adapte aux besoins sp\u00e9cifiques du syst\u00e8me incolore.<\/p>\n<p>En outre, il compl\u00e8te le 907 et, en particulier, il a un effet synergique lorsqu'il est utilis\u00e9 avec le TPO et le 819 dans les rev\u00eatements et les encres durcissant aux UV, les rev\u00eatements transparents pour le bois, les plastiques et les m\u00e9taux, ainsi que les vernis de surimpression. On peut supposer que sans la pr\u00e9sence du photo-initiateur 1173, ces sc\u00e9narios d'application industrielle complexes pourraient \u00eatre mis \u00e0 mal. Par exemple, dans l'impression de films plastiques, si la couleur est instable ou si le durcissement est incomplet, cela entra\u00eenera une augmentation significative du taux de rejet du produit, ce qui causera d'\u00e9normes pertes \u00e9conomiques \u00e0 l'entreprise. L'application du photo-initiateur 1173 est comme une couche d'armure solide pour ces industries, garantissant le bon d\u00e9roulement de la production et la haute qualit\u00e9 des produits.<br \/>\nD'un point de vue chimique plus approfondi, la structure mol\u00e9culaire du photo-initiateur 1173 d\u00e9termine qu'il peut g\u00e9n\u00e9rer efficacement des radicaux libres sous irradiation de lumi\u00e8re UV, initiant ainsi une r\u00e9action de polym\u00e9risation. Ce m\u00e9canisme de r\u00e9action chimique pr\u00e9cis est la raison fondamentale pour laquelle il se distingue des autres photo-initiateurs. En outre, son adsorption et sa r\u00e9activit\u00e9 sur diff\u00e9rentes surfaces mat\u00e9rielles ont \u00e9galement fait l'objet de recherches exp\u00e9rimentales approfondies et d'une optimisation, ce qui constitue une base th\u00e9orique solide pour sa large application.<\/p>\n<p><strong>Paquet :<\/strong> Tambour de 20 ou 25 kg.<\/p>\n<p><strong>Stockage :<\/strong><\/p>\n<p>Les produits sont conserv\u00e9s dans un entrep\u00f4t sec, propre et bien ventil\u00e9.<\/p>\n<p>\u00c9viter l'exposition \u00e0 la lumi\u00e8re et \u00e0 la chaleur.<\/p>\n<p>Prot\u00e9ger le produit des fuites, de la pluie et de l'insolation pendant le transport.<\/p>\n<h2><strong><b>Contactez-nous d\u00e8s maintenant !<\/b><\/strong><\/h2>\n<h4><strong><b>Si vous avez besoin de Price, veuillez indiquer vos coordonn\u00e9es dans le formulaire ci-dessous.
