R\u00e9ponse rapide :<\/strong> Powder-coating caking usually reflects a combination of temperature, time, pressure, humidity, particle-size distribution and formulation softening. Storage and handling conditions should be verified before changing the additive package.<\/p>\n

 <\/p>\n

Les rev\u00eatements en poudre ont tendance \u00e0 s'agglom\u00e9rer \u00e0 une certaine temp\u00e9rature, ce qui est principalement d\u00fb au ramollissement de la r\u00e9sine, de l'agent de nivellement et d'autres mat\u00e9riaux dans le rev\u00eatement en poudre lorsqu'ils sont expos\u00e9s \u00e0 la chaleur.<\/p>\n

Les r\u00e9sines des peintures en poudre thermodurcissables, qui constituent les principaux mat\u00e9riaux filmog\u00e8nes, sont des polym\u00e8res organiques de faible poids mol\u00e9culaire.<\/p>\n

 <\/p>\n

Ces r\u00e9sines ont une propri\u00e9t\u00e9 physique, \u00e0 basse temp\u00e9rature, c'est un \u00e9tat vitreux dur et cassant, lorsque la temp\u00e9rature augmente jusqu'\u00e0 un certain degr\u00e9, la r\u00e9sine commence \u00e0 se transformer en une certaine \u00e9lasticit\u00e9 et produit un \u00e9tat d'adh\u00e9sion, en dessous de cette temp\u00e9rature, la r\u00e9sine retourne \u00e0 l'\u00e9tat vitreux non adh\u00e9sif, l'\u00e9tat vitreux de la r\u00e9sine et l'\u00e9tat visco\u00e9lastique de la transformation mutuelle de la temp\u00e9rature est appel\u00e9 la temp\u00e9rature de transition vitreuse de la r\u00e9sine.<\/p>\n

 <\/p>\n

La temp\u00e9rature de transition vitreuse de la r\u00e9sine \u00e9poxy et de la r\u00e9sine polyester est d'environ 50 degr\u00e9s Celsius. La temp\u00e9rature de transition vitreuse de l'agent de nivellement \u200d-liquide est inf\u00e9rieure \u00e0 z\u00e9ro degr\u00e9 Celsius.<\/p>\n

 <\/p>\n

Plus la quantit\u00e9 de mat\u00e9riau \u00e0 faible temp\u00e9rature de transition vitreuse ajout\u00e9e \u00e0 la formulation du rev\u00eatement en poudre est importante, plus la temp\u00e9rature de transition vitreuse du syst\u00e8me est basse. La temp\u00e9rature de transition vitreuse du syst\u00e8me de poudre est positionn\u00e9e \u00e0 environ 40 degr\u00e9s Celsius au moment de la production, et cette temp\u00e9rature est fix\u00e9e comme une temp\u00e9rature de s\u00e9curit\u00e9 pour l'agglom\u00e9ration du rev\u00eatement en poudre. \u200d<\/p>\n

L'augmentation de la temp\u00e9rature facilite l'agglom\u00e9ration des produits de rev\u00eatement en poudre. Comment pr\u00e9venir l'agglom\u00e9ration des produits de rev\u00eatement en poudre dans notre travail ?<\/p>\n

Tout d'abord, nous devons \u00e9tablir un concept selon lequel<\/p>\n

 <\/p>\n

La prise en masse du rev\u00eatement en poudre \u00e0 une certaine temp\u00e9rature est une loi naturelle. Pour \u00e9viter la prise en masse du rev\u00eatement en poudre, l'ensemble du processus de production du rev\u00eatement en poudre, tel que le broyage, l'emballage, le stockage et le transport, doit \u00eatre inf\u00e9rieur \u00e0 la temp\u00e9rature de transition vitreuse des produits de rev\u00eatement en poudre. \u200d<\/p>\n

Sur la base de ce point de vue, les solutions suivantes sont disponibles.<\/p>\n

 <\/p>\n

1) Dans la production de r\u00e9sine de polyester, choisir certains alcools ou acides qui peuvent augmenter sa temp\u00e9rature de transition vitreuse, ou r\u00e9duire la quantit\u00e9 d'alcools qui peuvent abaisser la temp\u00e9rature de transition vitreuse de la r\u00e9sine pour augmenter la temp\u00e9rature de transition vitreuse de la r\u00e9sine de polyester.<\/p>\n

(2) R\u00e9duire la quantit\u00e9 de polym\u00e8res \u00e0 faible temp\u00e9rature de transition vitreuse utilis\u00e9s dans la formulation du rev\u00eatement en poudre, tels que l'agent de nivellement et l'agent d'all\u00e8gement, afin de garantir que la temp\u00e9rature de transition vitreuse du syst\u00e8me de rev\u00eatement en poudre ne sera pas r\u00e9duite.<\/p>\n

(3) Dans la production, les fragments bris\u00e9s de la bande d'acier doivent \u00eatre suffisamment refroidis avant d'entrer dans le processus de broyage, et la vitesse d'alimentation doit \u00eatre r\u00e9duite, le volume d'air induit doit \u00eatre augment\u00e9, et l'air d'entr\u00e9e doit \u00eatre \u00e9quip\u00e9 d'un conditionneur d'air froid pour contr\u00f4ler la temp\u00e9rature de broyage. Toutefois, si le broyage pr\u00e9c\u00e8de le refroidissement des morceaux de mat\u00e9riau broy\u00e9s, ces derniers moyens ne joueront pas un bon r\u00f4le, il faut envisager la m\u00e9thode de refroidissement forc\u00e9 des d\u00e9bris de mat\u00e9riau cass\u00e9 pour le traitement \u00e0 basse temp\u00e9rature, qui est plus efficace que l'ajout d'un syst\u00e8me de conditionnement d'air. \u200d<\/p>\n

L'\u00e9t\u00e9 approche et les rev\u00eatements en poudre pr\u00e9sentent souvent des amas de poudre et m\u00eame des grumeaux lorsqu'ils sont utilis\u00e9s. Cela est d\u00fb \u00e0 la temp\u00e9rature et \u00e0 l'humidit\u00e9 ambiantes \u00e9lev\u00e9es pendant la production, le stockage et le transport, et la temp\u00e9rature de transition vitreuse des rev\u00eatements en poudre est sup\u00e9rieure \u00e0 40 degr\u00e9s. Afin d'\u00e9viter que le rev\u00eatement en poudre ne s'agglom\u00e8re au cours du processus d'application, il convient de tenir compte des aspects suivants.<\/p>\n

1. Lors du choix de la r\u00e9sine, utiliser une r\u00e9sine ayant une temp\u00e9rature de transition vitreuse (TG) \u00e9lev\u00e9e. La temp\u00e9rature de transition vitreuse de la r\u00e9sine \u00e9poxy conventionnelle et de la r\u00e9sine polyester est d'environ 50\u2103, ce qui peut r\u00e9pondre \u00e0 la demande g\u00e9n\u00e9rale. Lorsque les exigences de stockage sont \u00e9lev\u00e9s, la r\u00e9sine synth\u00e9tique peut r\u00e9duire l'utilisation d'alcools qui va r\u00e9duire la temp\u00e9rature de transition vitreuse de la r\u00e9sine, \u00e9poxy durcissement disponible amine alicyclique.<\/p>\n

2. Dans la conception de la formulation du rev\u00eatement en poudre pour r\u00e9duire l'utilisation de polym\u00e8res \u00e0 faible temp\u00e9rature de transition vitreuse, tels que l'agent de nivellement, la temp\u00e9rature de transition vitreuse \u00e0 environ 30 \u2103, vous pouvez ajouter un peu moins. L'ajout de plastifiant r\u00e9duira le groupe rigide de la r\u00e9sine et abaissera le TG de la r\u00e9sine, et l'ajout d'un TGIC excessif abaissera \u00e9galement le TG de la r\u00e9sine.<\/p>\n

3. Les additifs auxiliaires comprennent un agent d'\u00e9coulement de la poudre s\u00e8che et un agent antiagglom\u00e9rant suppl\u00e9mentaire, du noir de carbone blanc. Le principal composant de l'agent d'\u00e9coulement de la poudre s\u00e8che est une mati\u00e8re organique en poudre de cire pour l'anti-adh\u00e9sion. L'agent anti-agglom\u00e9rant appartient principalement \u00e0 la classe des silicates des substances inorganiques, et la feuille est broy\u00e9e ensemble avec l'utilisation de tamis, peut jouer un r\u00f4le dans la pr\u00e9vention de l'adh\u00e9rence de la poudre. L'ajout de silice se fait principalement par fum\u00e9es, avec un poids sp\u00e9cifique faible, ce qui permet d'absorber facilement l'humidit\u00e9. Par cons\u00e9quent, lors de l'utilisation, il convient de bien disperser la silice, d'\u00e9viter l'humidit\u00e9 et de veiller \u00e0 ce que la couleur sombre ne pr\u00e9sente pas de taches blanches.<\/p>\n

4. Le processus de production contr\u00f4le principalement l'extrusion et le broyage. Lors de l'extrusion, la longue voie et le refroidissement physique par ventilateur peuvent r\u00e9duire efficacement la temp\u00e9rature des flocons, et lorsque les flocons sont refroidis, ils sont broy\u00e9s. Lors du broyage de la poudre, la vitesse d'alimentation peut \u00eatre r\u00e9duite, la quantit\u00e9 d'air induit peut \u00eatre augment\u00e9e de mani\u00e8re appropri\u00e9e et un refroidisseur peut \u00eatre ajout\u00e9 \u00e0 l'entr\u00e9e d'air pour r\u00e9duire la temp\u00e9rature dans la canalisation si n\u00e9cessaire. La poudre de broyage doit \u00eatre refroidie \u00e0 une temp\u00e9rature inf\u00e9rieure \u00e0 la temp\u00e9rature ambiante avant d'\u00eatre emball\u00e9e. Certaines usines de poudre seront emball\u00e9es dans une bo\u00eete de poudre avec deux sacs int\u00e9rieurs s\u00e9par\u00e9s, mais aussi pour emp\u00eacher l'accumulation de poudre, dans une certaine mesure pour emp\u00eacher l'agglutination de la poudre.<\/p>\n

5. Les poudres doivent \u00eatre stock\u00e9es dans un atelier sec et \u00e0 l'abri de la lumi\u00e8re ; certains produits tr\u00e8s brillants et les fleurs flottantes qui s'imbibent facilement doivent \u00eatre stock\u00e9s dans des entrep\u00f4ts climatis\u00e9s ou envelopp\u00e9s d'une couche de papier d'aluminium autour de l'isolant du produit. Pour le transport, il convient d'utiliser des v\u00e9hicules climatis\u00e9s ou des camions recouverts d'une toile d'ombrage, et non des camions-citernes, et d'\u00e9viter l'accumulation d'objets lourds.<\/p>\n

Conclusion : l'agglutination facile des mati\u00e8res premi\u00e8res en poudre \u00e0 haute temp\u00e9rature est un processus naturel, qui n'est pas n\u00e9cessairement un indicateur de l'\u00e9valuation des mati\u00e8res premi\u00e8res, qu'elles soient bonnes ou mauvaises. Outre l'anti-agglom\u00e9ration \u00e0 haute temp\u00e9rature, la pr\u00e9vention des incendies et des catastrophes doit \u00eatre importante, tout comme l'atelier doit arr\u00eater de fumer, interdire le chargement des voitures \u00e9lectriques, l'exposition des fils de l'\u00e9quipement, etc.<\/p>\n

La fa\u00e7on de traiter le mottage du rev\u00eatement en poudre.
\n1. Dans la production de r\u00e9sine de polyester, choisir un alcool ou un acide qui peut am\u00e9liorer sa temp\u00e9rature de transition vitreuse, ou r\u00e9duire la quantit\u00e9 d'alcool qui peut r\u00e9duire la temp\u00e9rature de transition vitreuse de la r\u00e9sine afin d'am\u00e9liorer la temp\u00e9rature de transition vitreuse de la r\u00e9sine de polyester.
\n2. Lors de la planification des formulations de rev\u00eatement en poudre, r\u00e9duire la quantit\u00e9 de polym\u00e8res \u00e0 faible temp\u00e9rature de transition vitreuse, tels que les agents de nivellement et les agents \u00e0 face longue, afin de s'assurer que la temp\u00e9rature de transition vitreuse du syst\u00e8me de rev\u00eatement ne baisse pas.
\n3. En termes de production, les fragments bris\u00e9s doivent \u00eatre suffisamment refroidis avant d'entrer dans le processus de broyage, la vitesse de broyage doit \u00eatre r\u00e9duite et le volume d'air doit \u00eatre augment\u00e9 pour contr\u00f4ler la temp\u00e9rature de broyage.<\/p>\n
