Cheap White Aluminium Oxide Grains Factory Malaysia

Silicate and hardener powder are mixed to make coating(glass beads manufacturers). When mixed, the silicon gel is precipitated on the surface of the hardener particles. A part of the gel is dispersed in the liquid due to the destruction of the stirring surface, then the coating is coated on the substrate and heated and hardened(black fused alumina). At this point, the gelation reaction accelerates, and soon the free water disappears and begins to dehydrate and agglomerate.

It is a coating material made of Mo, Mo Mn and other additives, which is coated on the ceramic surface in wet hydrogen at 1300 ~ 1700 ℃(pink corundum). After Ni plating, the joint metal is brazed with brazing materials. In the solid-liquid system, if the heat resistance of the joint is considered, the joint temperature should be raised as much as possible(black aluminum oxide blast media). Especially when the temperature is high, cooling and other issues need to be considered.


(cheap white aluminium oxide grains factory malaysia)However, considering the simple bonding process(white fused alumina), less deformation and deterioration of the base metal, the temperature of the binding part should be kept as low as possible. On the other hand, when the gelation is too few, the obtained film has poor water resistance and the film will blister during densification(black aluminium oxide). That is, the reaction between alkali silicate and hardener should be in a proper range.


At this time, if the proportion of the gelatinized part and the non gelatinized part is appropriate(white aluminum oxide), the film with good water resistance, adhesion and good appearance can be obtained. However, when the gelation part is too much before dehydration, the non condensing part will become less continuous(pink fused alumina), resulting in poor gloss and unevenness, cracking and poor adhesion (first adhered to silica gel).(cheap white aluminium oxide grains factory malaysia)


When the activity of hardener is too strong, it can not be simply reduced(white corundum). In order to adjust the reaction speed, in addition to changing the mixing ratio, the following operations should also be carried out: particle size change (comminution), specific surface area (firing conditions), composite oxide (mixed firing), surface covering(steel shot abrasive), modification of SiO2/MO on the binder surface, and mixing of alkali metals (I.i, Na, K).


The binder of zinc rich coating is ethyl silicate, which is formed by silica gel by hydrolysis(brown fused alumina price). The following is an example of coating metal. A small amount of multi-stage metal oxides, boric acid and phosphoric acid were dissolved in advance. As mentioned above, alkali silicate and hardener can react even at room temperature(glass bead abrasive). There is a problem of validity period. If the time is exceeded, various defects will be produced in the coating.


(cheap white aluminium oxide grains factory malaysia)The mixed coating consists of main agent mud and hardener mud, which are sold separately(black corundum). High melting point metal method high melting point metal method is also called "de law". At the same time, the alkali silicate part without gelation formed a strong glass membrane(garnet abrasive price). During the process of dehydration and condensation, the monomer base on the gel surface also dehydrate and agglomerate.
