Examples of factors affecting the life of Glass Blocks

For precious Glass Blocks, using the full length directly affects the production processing of capital, for using the unit, the use of Glass Blocks stature, the longer the more able to cut fruit processing products.

Influence the use of a piece of Glass Blocks full length there are many, the elements of the assumptions used to know these elements, then it can help a good unit extends the application of Glass Blocks are used to reduce the yield criterion.

First is the quality of the Glass Blocks, a piece of Glass Blocks, the quality of high and low, and has certain effect on the use of Glass Blocks stature, quality high and low about Glass Blocks produce processors, so choose high quality Glass Blocks is to ensure that the first condition of Glass Blocks using full length. The quality of the Glass Blocks first refers to the appearance of the Glass Blocks the stand or fall of quality and processing technology, choose high quality appearance (primary air bubbles may be no bubbles, no less stones, anhydrous grain, no scratch the surface of the Glass Blocks, marginal without crack, etc.) of the Glass Blocks to ensure that the use of Glass Blocks stature.

Second impact Glass Blocks using taking another major factor is using temperature stability, assuming that under constant temperature application will use life spans are long, assuming that often under temperature change conditions apply, Glass Blocks is simple the most will fracture.

In addition, the cleanliness of the Glass Blocks in the equipment and the equipment in addition to the above two primary factors is directly affecting the application of the Glass Blocks.

Glass Blocks in the heating furnace heating, if all Glass Blocks in the middle of the temperature is higher than the temperature of edge, Glass Blocks in the process of cooling and heat center shorten than cold shortening of edge, Glass Blocks are cooled to room temperature and temperature difference after all disappear, Glass Blocks edge length scales will be greater than the center, in the edge of Glass Blocks form larger contraction stress, to balance the uneven stress Glass Blocks type a saddle shape. Are the same, a piece of Glass Blocks within the furnace is heated, if ultimately delay temperature distribution in the plane of the edge is higher than the central, Glass Blocks in the process of cooling and shorten the hot Glass Blocks edge measure is greater than the center part of the cooler to shorten, all Glass Blocks are cooled to room temperature and temperature difference of sight, the center of the Glass Blocks scale will be greater than the size of edge, constitute a large tensile stress in Glass Blocks edge condition, to balance the uneven stress Glass Blocks all appear pot shape, moreover this kind of condition is a two-way street, is the center of the Glass Blocks out will be changes in both directions.

I. 2.3 random temperature dispersion

Both uneven temperature distribution is mainly due to improper operation caused, random uneven temperature distribution may be because the device, led by bad tempered furnace heating wire is part of the onset of damage, the orientation of the temperature sensor changes or distortion, Glass Blocks in the pile on the table is not reasonable, etc all can make the Glass Blocks balance, the random uneven temperature distribution will cause Glass Blocks plane direction during the course of heating uneven temperature distribution of Glass Blocks in cooling shortened different irregular area attack and no rules will cause the decreasing of the Glass Blocks bad flatness.

1.3 thermal deformation caused by uneven cooling

Well-known, Glass Blocks after heated to softening point was agile cooling, satisfy the compressive stress in the appearance of Glass Blocks attacks, in the interior of the Glass Blocks attack processes of tensile stress and compressive stress phase equilibrium is toughened Glass Blocks, toughened Glass Blocks after the first release compressive stress when by external force, and then attack tensile stress in the Glass Blocks appearance so that the strength of the toughened Glass Blocks is higher than general Glass Blocks. Toughened glass pieces of the existence of a Glass Blocks, persistent stress in Glass Blocks deformation of internal stress imbalance will also attack: when the appearance of the compressive stress is larger than the appearance to balance the stress at the compressive stress of Glass Blocks winding down, the same, the appearance of the compressive stress is larger than the appearance of the compressive stress to balance stress at Glass Blocks twist up, Glass Blocks in the process of cooling for two looks uneven cooling speed, the cooling speed of the appearance of attack appearance of stress is greater than the cooling speed is slow.
