line-height: 32px; widows: 1;">如何提高实心烧结砖的强度是每一个实心烧结砖厂家颇为关心的问题，从现在烧结砖的生产技术来讲，提高烧结砖的强度可以从以下的几个方面着手：</span><br /> <p style="margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em;

0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;">1.提高实心烧结砖砖机的成型压力</span><br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important; color: rgb(51, 51, 51);" /> 实心烧结砖砖机成型压力的提高kpl竞猜平台，使实心烧结砖的密度提高。只有提高砖坯的密度kpl竞猜平台，才能烧出高强度的烧结砖。实践证明，成型压力（2.2到2.3之间）MPa的砖坯，烧出砖抗压强度一般为（13.9到15之间）MPa，而成型压力达到3MPa的砖坯，烧出砖的抗压强度很容易达到20MPa。</span></span></p> <div> <span style="font-family: "Hiragino Sans GB", "Microsoft YaHei", Arial, sans-serif; font-size: 16px; line-height: 32px; widows: 1;"><span style="margin: 0px; padding: 0px; max-width: 100%; line-height: 32px; box-sizing: border-box !important; word-wrap: break-word !important;"> 2.适当提高实心烧结砖的温度</span><br style="margin: 0px; padding: 0px; max-width: 100%; line-height: 32px; color: rgb(51, 51, 51); box-sizing: border-box !important; word-wrap: break-word !important;" /> <span style="line-height: 32px;"> 同样的原料、同样的砖机生产出来的实心烧结砖砖坯，焙烧温度不同，实心烧结砖的强度也不一样。试验结果表明，实心烧结砖的抗压强度，随着隧道窑焙烧温度的提高而增大kpl竞猜平台。</span></span><br /> <p

!important;"> 3.适当延长实心烧结砖的保温时间</span></span></span></span></p> <p style="margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); line-height: 2em; box-sizing:

!important;">同样的升温、降温速度，实心烧结砖的烧结温度都为900℃，实心烧结砖保温时间不同，则实心烧结砖的抗压强度也不一样kpl竞猜平台kpl竞猜平台。实心烧结砖具有适宜的保温时间，对提高实心烧结砖抗压强度和质量是有益的。<br /> <span style="line-height: 32px;"> </span><span style="margin: 0px; padding: 0px; max-width: 100%; line-height: 32px; box-sizing: border-box !important; word-wrap: break-word !important;"> 4.推荐实心烧结砖采用低温长烧</span><br style="margin: 0px; padding: 0px; max-width: 100%; line-height: 32px; color: rgb(51, 51, 51); box-sizing: border-box !important; word-wrap: break-word !important;" /> <span style="line-height: 32px;"> 现在实心烧结砖普遍掺有内燃，且多采用“高温短烧”以提高产量为目标。实践证明，内燃砖采用“高温短烧”的烧成方法，虽然能提高产量kpl竞猜平台，但对实心烧结砖的产品质量是有一定影响，产品往往有黑心、黑疤kpl竞猜平台kpl竞猜平台、裂纹、压花等不良现象，抗压强度也有所降低。更为重要的是增加了煤耗kpl竞猜平台，浪费了能源，对眐pl竞猜平台kpl竞猜平台；ど肪巢焕?。因此，应提倡采用“低温长烧”的方法。</span></span></span></span><br
