锡槽底砖采用优质原料，经精密配料、成型、烘干和烧成、切铣磨加工和钻孔、成品烘干、检验等多道工序生产。产品的理化性能优良，外观尺寸精确，抗氢扩散能力、抗霞石化能力和抗碱侵蚀能力显著，经10余年连续使用后未出现表面霞石化剥落和开裂。特别是新型底砖FTB-40B具有氢扩散性低，热膨胀率低，导热系数低，弹性模量低，荷重软化温度高的优点。该产品用于整个浮法玻璃锡槽池底。
Adopted high quality raw materia , tin bath bottom blocks are produced with the processing of fine batching,moulding,drying fring, cxting,grinding,mlling,driling,finishedproductdrying, detecting,etc.The dimension is accurate and the physical and chemical properties especiallytheperformances of resistance to hydrogen difusion,flaking resistance and alkal atacking resistance are perfect, there was no any nephelineafter ten years service in tin bath. Especially new developed tin bath bottom block FTB-40B,it has advantages of lowhydrogen diffusion, low thermal expansion, low thermal conductivity , low elasticity modulus and high refractoriness underload.This product could be used in the whole bottom of float glass tin bath.
