Description de filtre en c\u00e9ramique poreuse<\/a> am\u00e9lioration de la qualit\u00e9
\nDepuis la mise en place de tests rigoureux en laboratoire, le filtre en mousse c\u00e9ramique n\u2019a pas satisfait \u00e0 la norme \u00e0 deux reprises dans des lots de r\u00e9sistance de 70 mesh, et le nombre de lots non conformes pour ces deux lots s\u2019\u00e9levait \u00e0 environ 1 500 pi\u00e8ces ; ce type de lot non conforme est le signe d\u2019une r\u00e9sistance instable. Une pi\u00e8ce contr\u00f4l\u00e9e au hasard ne r\u00e9pond pas \u00e0 la norme, et la pi\u00e8ce non conforme, apr\u00e8s un nouveau contr\u00f4le, est parfois jug\u00e9e conforme et peut \u00eatre remise en stock, tandis que parfois, le nouveau contr\u00f4le s'av\u00e8re \u00e0 nouveau non conforme et ce produit ne peut pas \u00eatre remis en stock ; les raisons de cette situation sont les suivantes :
\n1. Le broyage effectu\u00e9 par la machine \u00e0 p\u00e2te est irr\u00e9gulier, ce qui se traduit par une r\u00e9sistance \u00e0 la compression in\u00e9gale : de nombreuses \u00e9chantillons pr\u00e9sentent une r\u00e9sistance faible et la valeur moyenne n'est pas conforme \u00e0 la norme ;
\n2. Au cours de la phase de refroidissement et de mise au point du nouveau four \u00e0 rouleaux, un lot s'est r\u00e9v\u00e9l\u00e9 non conforme ; l'instabilit\u00e9 de la temp\u00e9rature du nouveau four a entra\u00een\u00e9 un processus de frittage anormal du produit ;
\n3. La viscosit\u00e9 de la suspension est instable, ce qui entra\u00eene l'instabilit\u00e9 de la filtre en c\u00e9ramique poreuse.<\/a> La quantit\u00e9 d'eau ajout\u00e9e aux ingr\u00e9dients pr\u00e9sentant les m\u00eames caract\u00e9ristiques techniques le m\u00eame jour a vari\u00e9, et cette variation est importante ; l'instabilit\u00e9 des mati\u00e8res premi\u00e8res est la cause directe de l'instabilit\u00e9 de la viscosit\u00e9 de la suspension.
\nApr\u00e8s l'apparition de ce probl\u00e8me, l'\u00e9quipe de l'atelier de production a proc\u00e9d\u00e9 \u00e0 une analyse rapide des causes et mis en place des mesures correctives en temps opportun. En fonction des causes \u00e0 l'origine des probl\u00e8mes li\u00e9s aux produits non conformes, le contenu et les m\u00e9thodes des mesures correctives ont \u00e9t\u00e9 d\u00e9finis. L'objectif est d'am\u00e9liorer la qualit\u00e9 des produits afin qu'ils soient plus soign\u00e9s et plus r\u00e9sistants.<\/p>\n
