I. Qualit\u00e9 du mat\u00e9riau (d\u00e9termine la stabilit\u00e9)
Types de pierre
Priorit\u00e9 : Vert de Jinan \/ Vert de Fujian \/ Santal noir indien
Caract\u00e9ristiques : grain fin et uniforme, sans fissure, sans impuret\u00e9, meilleure stabilit\u00e9
\u00c0 \u00e9viter : Les pierres marbr\u00e9es de couleurs m\u00e9lang\u00e9es, les mat\u00e9riaux dont la texture se superpose de mani\u00e8re \u00e9vidente.
Qualit\u00e9 des mat\u00e9riaux
Les \u00e9quipements de pr\u00e9cision doivent \u00eatre s\u00e9lectionn\u00e9s : Mat\u00e9riau de qualit\u00e9 A \/ Mat\u00e9riau de qualit\u00e9 00
Pas de fissures, pas de lignes de couleur, pas de cavit\u00e9s, r\u00e9sistance \u00e0 la d\u00e9formation \u00e0 long terme
II. Pr\u00e9cision de la plan\u00e9it\u00e9 (la plus critique)
Class\u00e9 par norme nationale : Grade 000, Grade 00, Grade 0, Grade 1, Grade 2
Inspection des panneaux LCD \/ Traitement au laser :
Doit \u00eatre de niveau 00 ou sup\u00e9rieur
Exigences communes :
Plan\u00e9it\u00e9 : \u2264 2\uff5e5 \u03bcm\/m
Rugosit\u00e9 : Ra \u2264 0.025\uff5e0.1 \u03bcm (finition miroir)
Une pr\u00e9cision insuffisante signifie que m\u00eame un \u00e9quipement co\u00fbteux ne peut pas mesurer avec pr\u00e9cision ou traiter de mani\u00e8re stable.
III. Pr\u00e9cision g\u00e9om\u00e9trique (perpendicularit\u00e9, parall\u00e9lisme)
Les \u00e9quipements de haute pr\u00e9cision n\u00e9cessitent de contr\u00f4ler non seulement la surface, mais aussi la qualit\u00e9 de l'eau :
perpendicularit\u00e9 lat\u00e9rale
Positionnement des rainures en T \/ trous filet\u00e9s
Parall\u00e9lisme global
Exigences g\u00e9n\u00e9rales pour l'inspection LCD et l'\u00e9quipement laser :
Perpendicularit\u00e9 : \u2264 0,005 mm \/ 100 mm
Pr\u00e9cision de la position du trou : \u00b10,01 mm
IV. Dimensions et \u00e9paisseur (la rigidit\u00e9 d\u00e9termine la d\u00e9formation)
Principe : plus la taille est grande, plus elle doit \u00eatre \u00e9paisse ; plus elle est lourde, plus elle est stable.
R\u00e9f\u00e9rence conventionnelle d'\u00e9paisseur :
Plateau Episs\u00e9
Les grandes tailles doivent \u00eatre dot\u00e9es de raidisseurs \/ de bords \u00e9pais.
M\u00e9thode d'installation
Appui \u00e0 trois points (nivellement naturel)
Support distribu\u00e9 multipoint (grandes tables)
Trous filet\u00e9s \/ rainures en T
Traitement \u00e0 la demande ; il est strictement interdit d'agrandir ou de modifier les trous de mani\u00e8re arbitraire par la suite.
La profondeur et la position des trous doivent \u00eatre d\u00e9termin\u00e9es \u00e0 l'avance.
VI. Adaptabilit\u00e9 \u00e0 l'environnement (d\u00e9termine la dur\u00e9e de vie)
Coefficient de dilatation thermique
Pr\u00e9f\u00e9r\u00e9 : (2.5\uff5e5)\u00d710-\u2076 \/\u2103
Amortissement des vibrations
Plus le grain est dense, meilleur est l'amortissement et plus forte est la r\u00e9sistance aux vibrations.
R\u00e9sistance \u00e0 la corrosion
Pour les salles blanches et les environnements acides ou alcalins, choisir un mat\u00e9riau dense et sans pores ; effectuer un traitement d'\u00e9tanch\u00e9it\u00e9 si n\u00e9cessaire.
R\u00e9sum\u00e9 minimaliste : Guide de s\u00e9lection en une phrase
Plate-forme en granit pour l'inspection des panneaux LCD et le traitement au laser :
Jinan Green Grade A material Grade 00 flatness sufficient thickness to ensure rigidity precision hole positioning three-point \/ distributed support clean room sealing treatment<\/p>\n\n\n\n
