Le stockage des poudres se fera g\u00e9n\u00e9ralement dans un endroit ventil\u00e9 et sec, et la temp\u00e9rature de l'espace de stockage ne doit pas d\u00e9passer 30 degr\u00e9s.<\/p>\n<p>&nbsp;<\/p>\n<p>Les diff\u00e9rentes vari\u00e9t\u00e9s de poudre ne peuvent pas \u00eatre plac\u00e9es ensemble pour \u00e9viter la pollution mutuelle. Diff\u00e9rents fabricants de poudre, dans la construction, la poudre doit \u00eatre recycl\u00e9e, c'est-\u00e0-dire qu'un lot utilis\u00e9 et ensuite le lot suivant, non utilis\u00e9 la poudre doit \u00eatre scell\u00e9e dans une bo\u00eete pour \u00e9viter la contamination.<\/p>\n<p>&nbsp;<\/p>\n<p>Environnement de la construction<\/p>\n<p>Les unit\u00e9s de construction de poudres ont des exigences diff\u00e9rentes en mati\u00e8re d'environnement, il y a des unit\u00e9s \u00e0 ciel ouvert et des unit\u00e9s ferm\u00e9es, il y a des ateliers de production \u00e0 travers le corps, il y en a plusieurs.<\/p>\n<p>&nbsp;<\/p>\n<p>L'environnement de construction de la poudre doit \u00eatre ind\u00e9pendant et \u00e9quip\u00e9 d'un dispositif de r\u00e9cup\u00e9ration de la poudre. La poudre non utilis\u00e9e ne peut pas \u00eatre plac\u00e9e dans la salle de pulv\u00e9risation. Chaque jour, avant et apr\u00e8s le travail, pulv\u00e9riser la pi\u00e8ce \u00e0 l'aide d'un fardage ou d'un aspirateur pour nettoyer le sol en profondeur. La concentration de poussi\u00e8re dans la salle de pulv\u00e9risation ne doit pas \u00eatre trop importante. Tout d'abord, ce n'est pas bon pour la sant\u00e9 humaine, et ensuite le point important est que la poudre dans un certain espace pour atteindre une certaine concentration produira une explosion, ce qui est tr\u00e8s dangereux. Les principaux composants de la poudre \u00e9tant des mat\u00e9riaux chimiques inflammables, la chambre de pulv\u00e9risation doit \u00eatre interdite au feu.<\/p>\n<p>&nbsp;<\/p>\n<p>Ph\u00e9nom\u00e8ne de perte de lumi\u00e8re des poudres et traitement<\/p>\n<p>(1) La poudre dans le four au-del\u00e0 de la dur\u00e9e et de la temp\u00e9rature sp\u00e9cifi\u00e9es est susceptible d'entra\u00eener une perte de lumi\u00e8re \u00e0 la surface. La temp\u00e9rature de la poudre de polyester \u00e9poxy est g\u00e9n\u00e9ralement constante et ne d\u00e9passe pas 190 degr\u00e9s. La temp\u00e9rature constante g\u00e9n\u00e9rale de la poudre de polyester pur ne d\u00e9passe pas 220 degr\u00e9s.<\/p>\n<p>&nbsp;<\/p>\n<p>Des mat\u00e9riaux diff\u00e9rents n\u00e9cessitent une \u00e9nergie thermique diff\u00e9rente, de sorte que le temps pass\u00e9 dans le four est diff\u00e9rent. Par exemple, le temps de placement dans le four d'un type d'aluminium, d'une plaque de fer mince, etc. ne d\u00e9passe g\u00e9n\u00e9ralement pas 15 \u00e0 20 minutes. Les grandes pi\u00e8ces m\u00e9talliques sont g\u00e9n\u00e9ralement plac\u00e9es dans le four pendant 30 \u00e0 60 minutes.<\/p>\n<p>&nbsp;<\/p>\n<p>(2) Dans la construction, pour r\u00e9duire les d\u00e9chets, la poudre recycl\u00e9e est ajout\u00e9e au nouveau m\u00e9lange de poudre, ce qui entra\u00eene souvent une perte de luminosit\u00e9 \u00e0 la surface de la pi\u00e8ce. La m\u00e9thode correcte consiste \u00e0 ajouter environ 3 kg de poudre (normale), mais ne doit g\u00e9n\u00e9ralement pas d\u00e9passer 5 kg, sous peine de perte de luminosit\u00e9.<\/p>\n<p>&nbsp;<\/p>\n<p>(3) la poudre est soumise \u00e0 une temp\u00e9rature \u00e9lev\u00e9e ou \u00e0 une surextrusion, ce qui entra\u00eene un ph\u00e9nom\u00e8ne de mottage. Cette situation entra\u00eene souvent une perte de luminosit\u00e9 de la poudre. Dans ce cas, il convient g\u00e9n\u00e9ralement d'\u00e9mietter la poudre \u00e0 l'aide d'un tamis, puis de la combiner avec la poudre non \u00e9miett\u00e9e, ce qui permet de r\u00e9soudre le probl\u00e8me.<\/p>\n<p>&nbsp;<\/p>\n<p>(4) Les poudres de diff\u00e9rents fabricants sont m\u00e9lang\u00e9es les unes avec les autres, en raison des interf\u00e9rences mutuelles, la poudre perd \u00e9galement de sa luminosit\u00e9. Si vous avez besoin d'une poudre d'un autre fabricant, vous devez utiliser un g\u00e9n\u00e9rateur \u00e9lectrostatique pour nettoyer le canon, le pistolet, le tube \u00e0 poudre et le milieu environnant, puis passer \u00e0 une autre poudre.<\/p>\n<p>&nbsp;<\/p>\n<p>(5) En r\u00e8gle g\u00e9n\u00e9rale, la poudre ne doit pas \u00eatre stock\u00e9e trop longtemps. Un stockage trop long modifie l'\u00e9clat, l'\u00e9clat g\u00e9n\u00e9ral de la poudre la plus \u00e9lev\u00e9e, la construction produit souvent un ph\u00e9nom\u00e8ne de perte de lumi\u00e8re. La poudre peu brillante, telle que le noir sans lumi\u00e8re, le gris sans lumi\u00e8re, etc., stock\u00e9e trop longtemps, est susceptible de pr\u00e9senter le ph\u00e9nom\u00e8ne d'ondulation du sable.<\/p>\n<p>&nbsp;<\/p>\n<p>(6) Poudre transparente et interf\u00e9rence avec d'autres poudres, dans la construction, tant que vous avez utilis\u00e9 de la poudre transparente, vous voulez changer les autres poudres, il faut que le pistolet, le canon d'alimentation en poudre et la chambre de pulv\u00e9risation soient bien nettoy\u00e9s.<\/p>\n<p><!-- lc-commercial-start --><\/p>\n<h2>Un itin\u00e9raire de s\u00e9lection pratique pour les projets li\u00e9s aux photoinitiateurs<\/h2>\n<p>Lorsque les acheteurs techniques ou les formulateurs \u00e9valuent des photoinitiateurs, le cadre de d\u00e9cision le plus utile concerne g\u00e9n\u00e9ralement la qualit\u00e9 de la polym\u00e9risation associ\u00e9e \u00e0 l'ad\u00e9quation \u00e0 l'application : quel paquet polym\u00e9rise de mani\u00e8re fiable, maintient une apparence acceptable et fonctionne toujours sous la lampe, l'\u00e9paisseur du film et les conditions du substrat du processus r\u00e9el.<\/p>\n<ul>\n<li><strong>Associez d'abord le paquet \u00e0 la lampe :<\/strong> Les lampes \u00e0 mercure, les LED UV et les syst\u00e8mes de lumi\u00e8re visible peuvent classer de la m\u00eame mani\u00e8re des photoinitiateurs tr\u00e8s diff\u00e9rents.<\/li>\n<li><strong>V\u00e9rifier la polym\u00e9risation en profondeur et la polym\u00e9risation de surface s\u00e9par\u00e9ment :<\/strong> un film sec en apparence peut \u00eatre faible en dessous.<\/li>\n<li><strong>\u00c9quilibrer le jaunissement avec la r\u00e9activit\u00e9 :<\/strong> La voie de polym\u00e9risation profonde la plus forte n'est pas toujours le meilleur choix commercial si la couleur ou le risque de migration deviennent inacceptables.<\/li>\n<li><strong>Utilisez la formule finale comme r\u00e9f\u00e9rence\u00a0:<\/strong> La charge de pigment, le paquet de monom\u00e8re et l'\u00e9paisseur du film peuvent tous modifier le classement apparent du m\u00eame initiateur.<\/li>\n<\/ul>\n<h3>R\u00e9f\u00e9rences de produits recommand\u00e9es<\/h3>\n<ul>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/fr\/product\/photoinitiator-819-irgacure-819-cas-162881-26-7\/\">CHLUMINIT 819<\/a>:<\/strong> Utile lorsqu'une formulation n\u00e9cessite une absorption plus forte et un soutien \u00e0 une cure plus profonde.<\/li>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/fr\/product\/irgacure-1173-cas-7473-98-5\/\">CHLUMINIT 1173<\/a>:<\/strong> Un point de comparaison pratique pour l'initiation classique par UV \u00e0 ondes courtes.<\/li>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/fr\/product\/photoinitiator-itx-cas-5495-84-1\/\">CHLUMINIT ITX<\/a>:<\/strong> Une ligne de support d'ondes longues utile dans de nombreux emballages d'encres d'imprimerie.<\/li>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/fr\/product\/photoinitiator-cq\/\">CHLUMINIT CQ<\/a>:<\/strong> Une r\u00e9f\u00e9rence directe pour les discussions sur le durcissement par la lumi\u00e8re visible et sensible \u00e0 la couleur.<\/li>\n<\/ul>\n<h3>FAQ pour les acheteurs et les formulateurs<\/h3>\n<p><strong>Pourquoi les m\u00e9langes de photoinitiateurs sont-ils si courants ?<\/strong><br \/>Parce qu'un produit peut contr\u00f4ler le jaunissement ou bien s'adapter \u00e0 la lampe, tandis qu'un autre am\u00e9liore la profondeur de durcissement ou les performances en vitesse de ligne, l'ensemble complet est souvent plus performant que n'importe quel grade individuel.<\/p>\n<p><strong>Une polym\u00e9risation incompl\u00e8te doit-elle toujours \u00eatre r\u00e9solue en ajoutant plus d'initiateur ?<\/strong><br \/>Pas automatiquement.
