摘要： The present disclosure relates to an absorbent tissue paper product comprising one ply (10) being an essentially continuous ply (10) of fibrous structure having a first side (1) and a second side (2), said first side (1) having a surface roughness arithmetical mean height (Sa1), and said second side (2) having a surface roughness arithmetical mean height (Sa2). Said ply has a micro-embossed structure and a difference between the surface roughness arithmetical mean heights of the first side (1) and the second side (2) is 7μm or less (│Sa1-Sa2│≤ 7μm), and said ply (10) having a bulk of at least 7.5 cm3/g. The disclosure also relates to a method and an apparatus for producing such an absorbent tissue paper product.

摘要： 一种无卤无机阻燃材料及其制备方法和应用，属于无机液相阻燃技术领域。无卤无机阻燃材料，由包括以下组分的原料混合制备得到：体积比为2.5:2.5:1～2:3:1硫酸铝水溶液、硫酸铁饱和水溶液和偏硅酸钠水溶液；所述偏硅酸钠水溶液和硫酸铝水溶液的摩尔浓度独立地为0.09～0.11mol/L；所述硫酸铁饱和水溶液为15～17℃条件下的饱和水溶液。该无卤无机阻燃材料作用于可燃物表面后，原料中各溶质组分能够在高温条件下发生分解反应，阻止可燃物的进一步燃烧；同时原料中各溶质组分在分解过程中吸热，降低可燃物表面温度，起到阻燃效果。且阻燃后剩余附着物易回收，对环境几乎无负面影响。
