南阳珍珠岩保温板

不同产地膨胀珍珠岩的筒压强度、孔隙率、粒度分布等性能,以及以其为主要原料制备的膨胀珍珠岩保温板的性能。结果表明:膨胀珍珠岩孔隙率越大,保温板的导热系数越低,保温性能越好;膨胀珍珠岩筒压强度高时,保温板的导热系数低、抗压强度高;科学的粒度分布有利于膨胀珍珠岩保温板保温性能的优化和提升;膨胀珍珠岩表面MTMS预聚物包覆有利于膨胀珍珠岩及膨胀珍珠岩保温板强度的提升,并可优化其保温性能;膨胀珍珠岩筒压强度、孔隙率、粒度分布等性能相互牵制、相互影响,要制备出性能优良的膨胀珍珠岩保温板,需使各项性能协调作用。

The perlite separates the heat preservation board (FSG hatred water heat preservation board) is take the inflated pearlite bulk as an aggregate, joins the water-repellent and the cementing agent carries on the heat insulation waterproofing heat preservation board which working procedures and so on configuration, screening, compression formation, drying make. The FSG hatred water heat preservation board has solved each kind of building roofing heat preservation, the heat insulation and the waterproof function effectively in a body's technical difficult problem, saved the massive constructions and the service fund.product characteristic:The nature is light, and heat preservation heat insulation performance fine fire protection. Dustproof. Moisture-proof, does not distort the modification, not rottenly mildewy, the non-toxic tasteless hatred water performance to be good, hates Shui Lvke to reach above 98% to construct safely easy and feasible, the roofing and the wall surface glue may the natural ore be raw materials, has the good environment-protective.

场上单一**保温材料易燃,存在安全隐患。无机材料保温效果不理想。研制出高强轻质,防火保温隔热材料拥有广阔市场空间。本实验采用水玻璃胶结经硅气凝胶浸泡后的膨胀珍珠岩颗粒,装入模具热压制板。实验表明,板材抗压强度为0.2MPa—0.3MPa,分析硅气凝胶未能充分浸入膨胀珍珠岩颗粒。憎水性材料,分析经硅气凝胶改性导致板材憎水性能增强。导热系数小可达0.049W·(m·k)-1,分析硅气凝胶部分浸入颗粒内部且充满板材空隙,水玻璃密封效果较好。膨胀珍珠岩保温板是集保温、隔热和防水功能于一体的新型外墙保温板材。珍珠岩保温板质轻且保温隔热性能优良,防火防尘防潮、不变形改性、不腐烂发霉、无毒无味憎水性能好(憎水率可达98%以上),施工安全简单易行,屋面与墙面粘贴均可以**矿石为原料,有良好的环保性。但是珍珠岩在使用过程中会产生裂纹,产生裂纹

FSG憎水树脂膨胀珍珠岩保温板屋面保温隔热操作工艺1、工艺流程基层清理─→弹线找坡─→管根固定─→隔汽层铺设─→抹找平层。2、操作步1）先将接触面清扫干净。2）按设计坡度及流水方向，找出屋面坡度走向，确定FSG憎水树脂膨胀珍珠岩保温板保温层的厚度范围。（3）穿越结构层的管根在FSG憎水树脂膨胀珍珠岩保温板保温层施工前，应用细石砼塞堵密实。（4）FSG憎水树脂膨胀珍珠岩保温板应紧靠在需保温的基层表面上并应铺平垫稳，分层铺设的板材，其上、下两层的接缝应错开，板之间用胶水贴严、粘牢，各层板间的缝隙，应用同类材料的碎屑嵌填密实，表面应与相邻两板的高度一致排汽槽的留置应与砂浆找平层分格缝一致，做找平层之前用宽约6cm的镀锌铁皮覆盖排汽道之上，以免水泥砂浆堵塞。
