1. Πώς να αποθηκεύσετε τα πάνελ φωτισμού;
Τα τελειωμένα πάνελ φωτισμού θα πρέπει να τοποθετούνται σε ξηρή και αεριζόμενη αποθήκη, όχι σε ύπαιθρο. Μέσα σε ένα χρόνο από την παραγωγή του φύλλου FRP, η χημική αντίδραση συνεχίστηκε και η αντοχή έχει ενισχυθεί. Μετά την απορρόφηση νερού, θα επηρεάσει τη διαδικασία σκλήρυνσης της σανίδας, η σανίδα θα ανθίσει, επηρεάζοντας τη διαπερατότητα του φωτός και την εμφάνιση της σανίδας και σε σοβαρές περιπτώσεις, η σανίδα θα απορριφθεί
1. Η επίδραση της περιεκτικότητας σε ίνες γυαλιού του φύλλου FRP στην ποιότητα του φύλλου;
Glass fiber is the reinforcing material of the lighting board, and it is the fundamental guarantee of strength and toughness. Today's lighting board production lines generally use two technologies: cut yarn or chopped strand mat. The cost of cutting yarn is low, and the adjustment is flexible during production. The disadvantage is that due to the production process, the glass fiber content of the plate is low, only 22 percent , so the strength of the plate is poor and the plate is brittle and easy to break. Cracks are easy to occur when fixing, and it is easy to cause water leakage problems. The cost of chopped strand mat is high, but the glass fiber content of the board can be relatively high, generally more than 30 percent , so the strength and toughness of the board are very good. Will not crack during handling and nailing. In the production of felts, the thicker products will be produced by stacking two or even three felts to meet the requirements of product thickness and glass fiber content. Clients may worry about tiering. This concern is unnecessary, and the same method is used in the automotive and aerospace industries to achieve strength. We have done a similar experiment: use 60 layers of 600G/M2 felt to make a product with a thickness of 80CM, and cut it along the thickness direction to do a strength test and there is no difference between the normal production board. In addition, due to the high resin content of the board produced by the cutting process, the flow of the resin will be thinner at the corners of the board during production, the thickness of the section will be uneven, and the thin position will be particularly vulnerable to damage. At the same time, the corner arcs of the plate shape are relatively large, which is quite different from the shape of the steel plate, and the overlap with the steel plate is not good.
