Detailed introduction

Product Introduction

When an alumina plant leaches alumina from bauxite or sintered bauxite, some insoluble substances are generated. These substances tend to accumulate in the equipment used. Set and equipment Deposits of scale build up on the walls of equipment such as pipelines, evaporation tanks, and heat exchangers. The presence of these substances is detrimental to the operation of alumina production, as they lead to processing losses and significantly reduce the heat transfer efficiency of equipment and devices—including heat exchange tubes, boiling tanks, and pipeline walls—due to severe scaling. Therefore, preventing and removing scale buildup has become a critical task for alumina plants aiming to save energy and reduce consumption. The chemical composition and phase structure of scale formed during the alumina production process are as follows: ： The main mineral phase component of fouling on the heating tubes of the casing preheater is sodium silicate slag. The fouling on the evaporator is primarily sodium aluminosilicate. ， In particular, it precipitates in the form of kalsilite. This occurs because, during the evaporation process, the solubility of silica in the sodium aluminate solution decreases as the evaporation temperature rises. As a result, the concentration of silica in the mother liquor becomes supersaturated during evaporation, leading to its precipitation in the form of sodium aluminosilicate and the formation of scale on the tank walls. The scale formed during the evaporation process also contains certain amounts of substances such as sodium carbonate and sodium sulfate. Through research, we have investigated the formation patterns of scale on the heating surfaces during the evaporation of the mother liquor and the effects of scale-inhibiting additives on mitigating scale formation on these heating surfaces. ， For this type of situation, our company has developed a special scale-inhibiting agent specifically designed for aluminum oxide evaporation. This scale-inhibiting agent demonstrates remarkable effectiveness. ， It can effectively slow down the rate of scale formation on the heating surface and also help loosen existing scale on the heating surface. ， Easy to clean.

Instructions for use

Introduce the liquid to be processed into the system at a certain distance before it enters the evaporation equipment. It enables the agent to be thoroughly mixed with the liquid to be treated. ;The dosage is generally administered by counting. The metering pump introduces the system, where aluminum oxide evaporates per cubic meter of liquid to be treated, providing specialized scale inhibition. agent The appropriate addition amount for PO-606 is: 8g ~ 20g , specific dosage depends on the root. Determined by water body and working conditions. 。
