Low price enamel glass lined equipment

The core parts of enamel glass lined equipment are enamel glass layer and metal substrate.A high-quality enamel layer requires the use of high-purity porcelain glaze,which can form a dense,smooth,and corrosion-resistant surface through proportioning and complex firing processes.Some low-priced equipment manufacturers,in order to reduce costs,may use inferior porcelain glazes with high impurity content,which greatly reduces the performance of the enamel layer.
The quality of the metal substrate is equally crucial.High quality enamel equipment usually uses steel such as low-carbon steel or stainless steel,which has good strength and toughness.But low-priced equipment may use recycled steel or inferior steel,whose composition is unstable and contains a lot of impurities and defects.This not only affects the overall strength of the equipment,but may also cause adverse reactions with the enamel during the enamel firing process,resulting in weak adhesion of the enamel layer and easy detachment.

The production of enamel glass lined equipment requires multiple complex processes,including pre-treatment of the metal substrate,enamel coating,and high-temperature firing.Strict quality control is required at every stage to ensure the performance of the equipment.However,low-priced equipment manufacturers often simplify their production processes in pursuit of greater profits.

In the pre-treatment stage of metal substrates,normal processes require rust removal,degreasing,sandblasting,and other treatments to remove surface oil stains,rust,and oxide scales,providing a good foundation for the adhesion of porcelain glaze.However,low-priced equipment may omit some steps or shorten processing time,resulting in unclean surface treatment of the metal substrate and weakened bonding between the enamel and the metal substrate.
High temperature firing is a key step in forming an excellent enamel layer.Different porcelain glazes require specific firing temperature and time curves to ensure that the glaze is fully melted,flows,and uniformly adheres to the surface of the metal substrate.Low price equipment manufacturers may lower the firing temperature or shorten the firing time,which can save energy and reduce costs,but may prevent the enamel layer from achieving ideal performance,such as insufficient hardness and poor corrosion resistance.
Strict quality inspection is an important link in ensuring the quality of enamel glass lined equipment.Legitimate manufacturers will conduct inspections on each device,including visual inspection,measurement of enamel layer thickness,pressure resistance test,corrosion resistance test,etc.Low price equipment manufacturers may reduce testing items or lower testing standards,or even omit some testing steps.
For example,in the detection of the thickness of the enamel layer,if the thickness is uneven or too thin,it will affect the corrosion resistance and service life of the equipment.However,low-priced equipment may not perform thickness measurement,resulting in some equipment with quality hazards entering the market.In terms of pressure resistance and corrosion resistance tests,low-priced equipment manufacturers may use lower test pressures and shorter test times,which cannot truly reflect the performance of the equipment in actual use.
When purchasing enamel equipment,manufacturers are required to provide detailed quality inspection reports,including inspection results for appearance,measurement of enamel layer thickness,pressure resistance test,corrosion resistance test,and other related items.By reviewing the quality inspection report,one can understand the quality status of the equipment and ensure that the purchased equipment meets relevant standards and requirements.
Low priced enamel glass lined equipment often has many problems in raw materials,production processes,and quality testing,making it difficult to ensure its quality.When purchasing glass lining equipment,enterprises should not only focus on price,but also comprehensively consider factors such as equipment quality,performance,and after-sales service,and choose products with reliable quality and high cost-effectiveness to ensure the production safety and economic benefits of the enterprise.
