High-quality fiberglass Statue sculpture needs to be considered from comprehensive factors such as material selection and process quality control standards. Although fiberglass sculpture material belongs to one of the low-cost materials, material and process requirements directly affect the effect of fiberglass sculpture and its later maintenance. Today, fiberglass sculpture manufacturers will talk about how to select high-quality fiberglass sculpture.
Selection of raw materials for fiberglass molds:
The raw materials of high-quality hand-pasted fiberglass sculpture molds are mainly resins, reinforcing materials and auxiliary materials. Reasonable selection of raw materials is an important link to ensure product quality and reduce cost. When selecting raw materials, the following conditions must be met:
(1) To meet the performance requirements of product design; (2) to adapt to the characteristics of the hand paste forming process; (3) cheap, adequate supply.
At present, the main raw materials are resin, reinforcing fiber (glass fiber cloth, chopped felt, surface felt), rubber coat, curing agent, accelerator, demoulding agent, color, toughening agent, filler (quartz powder, diamond powder, cast stone powder, asbestos powder), etc.
1. Selection of resin:
It is very important for high-quality Fiberglass Statues sculpture to choose resin varieties for hand paste molding, which is directly related to product quality and production process. Therefore, the type of resin must be determined according to product performance, service conditions, and process requirements.
High-quality fiberglass sculpture resin belongs to organic matter, which has a certain taste. It should have a certain peculiar smell after smelling directly or rubbing, so it can be identified by smell. The feeling of resin products is relatively warm, the temperature is faster, there is no cold sucker feeling or feeling is shorter. Resin products have a small proportion.
Firstly, two kinds of resins, 001 *7 and 201 *7, can be distinguished by using different wet and true densities. A little resin can be put into a saturated salt brine. The floating resin is 201 *7 anion resin, and the sinking resin is 001 *7 anion resin.
In identifying the strong and weak type of anodic resin
First, the appearance of strong acidic cationic resin is brown, while weak acidic cationic resin is milky white or light yellow.
Secondly, the volume expansion of cation resin is judged by the transformation expansion rate. The volume expansion of cation resin is changed from hydrochloric acid to H type, and then from caustic soda to Na type. Weak acidic resin is obviously larger than strong acidic resin.
Finally, the strong and weak anion resins can be identified by immersing them in phenolphthalein-added sodium hydroxide for 10 minutes. After being washed with non-ionic water, the strong anion resins are purple, the macroporous strong anion resins are pink, and the weak anion resins remain unchanged.
