Its low price and high dry strength make it a common traditional option.<\/p>\n\n\n\n<p data-block-type=\"core\">However, as steel plants place greater emphasis on continuous production, environmental requirements, and briquette quality, more companies are beginning to reconsider the limitations of water glass binding agents.<\/p>\n\n\n\n<p data-block-type=\"core\">So, how does water glass compare with a modern composite binding agent?<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"what-is-a-water-glass-binder\" data-block-type=\"core\"><strong>What Is a Water Glass Bin<\/strong><strong>der<\/strong><strong>?<\/strong><strong><\/strong><\/h2>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full is-resized\" data-block-type=\"core\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2026\/05\/Image-2-1.png\" alt=\"water glass\" class=\"wp-image-19290\" style=\"width:500px\" srcset=\"https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2026\/05\/Image-2-1.png 1024w, https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2026\/05\/Image-2-1-300x300.png 300w, https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2026\/05\/Image-2-1-150x150.png 150w, https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2026\/05\/Image-2-1-768x768.png 768w, https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2026\/05\/Image-2-1-12x12.png 12w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Water Glass<\/figcaption><\/figure>\n\n\n\n<p data-block-type=\"core\">Water glass, or sodium silicate, is an inorganic liquid binder&nbsp;commonly used in cold briquetting processes. It works mainly through a dehydration hardening mechanism.<\/p>\n\n\n\n<p data-block-type=\"core\">During drying, water gradually evaporates and silicate gel structures form inside the briquette, creating bonding strength. After complete drying, briquettes made with water glass can achieve relatively high cold&nbsp;compressive strength&nbsp;(CCS).<\/p>\n\n\n\n<p data-block-type=\"core\">Because of its availability and low cost, water glass has long been used in:<\/p>\n\n\n\n<ul class=\"wp-block-list\" data-block-type=\"core\">\n<li data-block-type=\"core\">Steel mill waste briquetting<\/li>\n\n\n\n<li data-block-type=\"core\">Coal briquette production<\/li>\n\n\n\n<li data-block-type=\"core\">Iron ore fines agglomeration<\/li>\n\n\n\n<li data-block-type=\"core\">Mineral powder pelletizing<\/li>\n<\/ul>\n\n\n\n<p data-block-type=\"core\">However, its bonding mechanism also creates several <strong>practical limitations<\/strong>&nbsp;during production and transportation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"main-problems-of-water-glass-binding-agents\" data-block-type=\"core\"><strong>Main Problems of Water Glass Binding Agents<\/strong><strong><\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"poor-wet-strength-before-drying\" data-block-type=\"core\"><strong>Poor Wet Strength Before Drying<\/strong><strong><\/strong><\/h3>\n\n\n\n<p data-block-type=\"core\">One of the biggest disadvantages of water glass binder is its<strong> low wet strength<\/strong>.<\/p>\n\n\n\n<p data-block-type=\"core\">Since the bonding force mainly develops after dehydration, wet briquettes often remain weak before moisture is fully removed. Inside the briquette, the silicate gel network is not yet completely formed, resulting in limited bonding ability during the early stage.<\/p>\n\n\n\n<p data-block-type=\"core\">This can lead to:<\/p>\n\n\n\n<ul class=\"wp-block-list\" data-block-type=\"core\">\n<li data-block-type=\"core\">Briquette deformation<\/li>\n\n\n\n<li data-block-type=\"core\">Cracking during handling<\/li>\n\n\n\n<li data-block-type=\"core\">Powder loss during transportation<\/li>\n\n\n\n<li data-block-type=\"core\">Low drop strength<\/li>\n<\/ul>\n\n\n\n<p data-block-type=\"core\">In many plants, wet briquettes made with sodium silicate can only withstand around 1&nbsp;drop before breaking&nbsp;during the drop test. This creates problems during conveying, stacking, and transportation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"heavy-dependence-on-drying\" data-block-type=\"core\"><strong>Heavy Dependence on Drying<\/strong><strong><\/strong><\/h2>\n\n\n\n<p data-block-type=\"core\">Because water glass relies heavily on dehydration hardening, drying becomes a critical step.<\/p>\n\n\n\n<p data-block-type=\"core\">For factories without drying systems, natural air drying may take several days depending on humidity and weather conditions. This slows production turnover and requires large storage areas for curing.<\/p>\n\n\n\n<p data-block-type=\"core\">For many steel plants and recycling facilities, adding a dryer also means:<\/p>\n\n\n\n<ul class=\"wp-block-list\" data-block-type=\"core\">\n<li data-block-type=\"core\">Higher fuel consumption<\/li>\n\n\n\n<li data-block-type=\"core\">Increased operating costs<\/li>\n\n\n\n<li data-block-type=\"core\">Additional equipment investment<\/li>\n<\/ul>\n\n\n\n<p data-block-type=\"core\">This is especially inconvenient for plants seeking continuous and efficient briquetting production.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"high-silicon-content\" data-block-type=\"core\"><strong>High Silicon Content<\/strong><strong><\/strong><\/h2>\n\n\n\n<p data-block-type=\"core\">Another concern with water glass binding agents is silicon introduction.<\/p>\n\n\n\n<p data-block-type=\"core\">Since sodium silicate  itself contains silicon, excessive use may increase Si content in the final briquettes. In some steelmaking and recycling applications, additional silicon may affect slag volume or reduce metal recovery efficiency.<\/p>\n\n\n\n<p data-block-type=\"core\">For steel plants that require stricter chemical composition control, low-silicon binding agents are becoming increasingly important.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"why-composite-binding-agents-are-becoming-more-popular\" data-block-type=\"core\"><strong>Why Composite Binding Agents Are Becoming More Popular<\/strong><strong><\/strong><\/h2>\n\n\n\n<p data-block-type=\"core\">Compared with traditional water glass binder, modern composite binding agents are designed to provide more balanced performance in both wet and dry conditions.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large is-resized\" data-block-type=\"core\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2026\/05\/IMG_4732-1-1024x683.jpg\" alt=\"jianjie briquette binder for steel waste\" class=\"wp-image-19276\" style=\"width:500px\" srcset=\"https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2026\/05\/IMG_4732-1-1024x683.jpg 1024w, https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2026\/05\/IMG_4732-1-300x200.jpg 300w, https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2026\/05\/IMG_4732-1-768x512.jpg 768w, https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2026\/05\/IMG_4732-1-1536x1024.jpg 1536w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">\u5efa\u6770\u590d\u5408\u7c98\u7ed3\u5242<\/figcaption><\/figure>\n\n\n\n<p data-block-type=\"core\">A <a href=\"https:\/\/www.jianjiebinder.com\/zh\/composite-binder-for-iron-ore-pellets\/\" data-type=\"post\" data-id=\"17773\">composite briquetting binder<\/a> usually combines organic and inorganic materials through multi-component formulation technology.
