La production de acrylique de haute qualit\u00e9<\/a> Les exigences en mati\u00e8re de technologie des mati\u00e8res premi\u00e8res et de machines sont \u00e9lev\u00e9es, et la difficult\u00e9 et le co\u00fbt de production ne sont pas \u00e0 la port\u00e9e des petits ateliers ordinaires, en particulier pour le moulage des feuilles d'acrylique. Par cons\u00e9quent, le prix de l'acrylique est g\u00e9n\u00e9ralement plus \u00e9lev\u00e9. Afin de r\u00e9pondre \u00e0 la qu\u00eate de prix bas de certains clients, de nombreuses plaques de mauvaise qualit\u00e9 et \u00e0 bas prix sont apparues sur le march\u00e9. Elles portent toutes le nom d'acrylique, mais ne sont que des panneaux organiques ordinaires ou des panneaux composites (panneaux sandwich). La plupart d'entre eux sont fabriqu\u00e9s \u00e0 partir de mat\u00e9riaux enti\u00e8rement recycl\u00e9s et leur prix est bas.<\/p>\n\n\n\n

La recherche de la qualit\u00e9 \u00e9tant toujours le fil conducteur, comment les consommateurs peuvent-ils faire face \u00e0 un march\u00e9 h\u00e9t\u00e9rog\u00e8ne et choisir les produits qui leur conviennent ? Voici quelques astuces :<\/p>\n\n\n\n

  1. M\u00e9thode d'observation<\/strong>:
    C'est l'approche la plus courante, la plus intuitive et la plus \u00e9conome en main-d'\u0153uvre. Apr\u00e8s une longue p\u00e9riode dans cette industrie, vous pouvez voir la qualit\u00e9 du carton, s'il est m\u00e9lang\u00e9 avec des mat\u00e9riaux recycl\u00e9s ou s'il s'agit d'un carton organique ordinaire. La couleur est pure, la plaque de coul\u00e9e transparente est bleut\u00e9e \u00e0 la lumi\u00e8re, il y a des piq\u00fbres \u00e0 l'int\u00e9rieur de la plaque et l'odeur est tr\u00e8s piquante. Il s'agit de m\u00e9thodes tr\u00e8s pratiques.<\/li>
  2. M\u00e9thode de combustion<\/strong>:
    Cette m\u00e9thode est la plus efficace. Pour savoir si la qualit\u00e9 du panneau est satisfaisante, si le revendeur utilise d'autres sous-panneaux comme panneau de qualit\u00e9, il suffit de br\u00fbler un coin. La feuille acrylique de haute qualit\u00e9 ne s'enflamme pas imm\u00e9diatement lorsqu'elle est br\u00fbl\u00e9e, en particulier la feuille coul\u00e9e ne peut pas \u00eatre retir\u00e9e apr\u00e8s avoir br\u00fbl\u00e9.<\/li>
  3. M\u00e9thode de transmission de la lumi\u00e8re<\/strong>:
    Cette m\u00e9thode est d\u00e9riv\u00e9e des caract\u00e9ristiques de transmission de la lumi\u00e8re de l'acrylique. Elle permet d'\u00e9mettre une lumi\u00e8re blanche \u00e0 travers la plaque acrylique. Si une couleur jaune ou bleue est d\u00e9tect\u00e9e, cela peut indiquer que la qualit\u00e9 de l'acrylique est incorrecte, car la transparence de la plaque acrylique Le taux de lumi\u00e8re est tr\u00e8s \u00e9lev\u00e9 et la lumi\u00e8re apr\u00e8s avoir travers\u00e9 est une lumi\u00e8re blanche, qui n'absorbera pas la couleur de la lumi\u00e8re.<\/li>
  4. M\u00e9thode de collage<\/strong>:
    \u00c9galement appel\u00e9e m\u00e9thode de fusion \u00e0 chaud, elle se distingue par la diff\u00e9rence d'adh\u00e9rence entre un mat\u00e9riau acrylique de bonne qualit\u00e9 et un mat\u00e9riau acrylique de mauvaise qualit\u00e9. Par exemple, les mat\u00e9riaux acryliques de mauvaise qualit\u00e9 se collent les uns aux autres et sont difficiles \u00e0 s\u00e9parer apr\u00e8s avoir \u00e9t\u00e9 fondus, alors que les mat\u00e9riaux acryliques de bonne qualit\u00e9 se s\u00e9parent facilement.<\/li>
  5. M\u00e9thode des solvants<\/strong>:
    Il est recommand\u00e9 de placer les aquariums de deux mat\u00e9riaux dans deux gobelets remplis d'ac\u00e9tone. Retirez-les au bout de 24 heures. Le mat\u00e9riau de surface en r\u00e9sine non satur\u00e9e va gonfler, le panneau acrylique va gonfler et la partie immerg\u00e9e va se d\u00e9tacher.<\/li><\/ol>","protected":false},"excerpt":{"rendered":"","protected":false},"author":3,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-20713","post","type-post","status-publish","format-standard","hentry","category-industrial-news"],"yoast_head":"\nHow
