HUALONG CASTING MATERIAL

The detachable insulation cover of the casting vulcanizer is more suitable for the equipment

During the operation of the casting vulcanizer, high temperature will be generated, and a large amount of heat will be lost, resulting in a waste of energy. Therefore, the thermal insulation of casting vulcanizers is the premise of improving production efficiency. Therefore, the removable insulation cover of the vulcanizer is especially suitable for the vulcanizer.

What should be paid attention to when casting vulcanizer

The casting vulcanizer found that the tape and the heating plate were bonded together after the vulcanization of individual users in use. The reason for this problem is that the user does not put spacers such as newspapers or talcum powder between the upper and lower heating plates according to the operation requirements.

Installation of vulcanizer plate of casting vulcanizer

The cast vulcanizer plate is used to place the model of the vulcanized product, and the pressure is transmitted to the model through the plate to heat the model. The vulcanizer plate moves in the guide rail. Under the action of the pin plug, the upper stroke of the plate is not restricted, and the upper plate can be directly reached. The downstroke is limited. Therefore, a positioning stopper is installed on the guide rail to determine the lower limit position of each plate, and at the same time, the distance between the plates is ensured so that the product model can be placed.

Structure of main parts of casting vulcanizer

The pressure generated in the hydraulic cylinder of the casting vulcanizer acts between the upper and lower beams. Beam: The beam is bent during the work, and the column is stretched. Beams and columns generate considerable stress because even a small vulcanizer can generate forces of 2-6 meganewtons. Therefore, a lot of stress is generated on the beam and the column. In order to ensure the structural strength and rigidity, the beams and columns are made of solid. The beams are generally cast in cast iron. The shape of the beam is selected according to the conditions of the strength of the part. The maximum bending distance is in the middle of the beam, so the middle stress is the largest.

Properties of Basic Phenolic Resin

Basic Phenolic Resin synthesized by using phenol and formaldehyde as raw materials and using alkali (NaOH, KOH, LiOH) as a catalyst. Because the resin contains a large amount of alkali, the phenolic hydroxyl group in the resin exists in the form of phenolic anion, and the resin contains a large amount of alkali. It has a certain alkalinity, so it has good water solubility, and the curing agent used is generally an organic fat of polyol.
