Principais aplica\u00e7\u00f5es<\/h3>\n

Celulose e papel:<\/strong> Utilizado nos processos de cozedura da pasta de papel, deslenhifica\u00e7\u00e3o e fabrico de papel.<\/p>\n

Detergentes e sab\u00e3o:<\/strong> Fundamental para a s\u00edntese de sab\u00e3o, a produ\u00e7\u00e3o de detergentes sint\u00e9ticos e a refina\u00e7\u00e3o de \u00f3leos animais e vegetais.<\/p>\n

Ind\u00fastria t\u00eaxtil:<\/strong> Atua como agente desengomante, agente de lavagem e agente de merceriza\u00e7\u00e3o para tecidos de algod\u00e3o.<\/p>\n

S\u00edntese qu\u00edmica:<\/strong> Produz produtos qu\u00edmicos org\u00e2nicos (\u00e1cido f\u00f3rmico, fenol) e inorg\u00e2nicos (b\u00farax, cianeto de s\u00f3dio).<\/p>\n

Petr\u00f3leo e Metalurgia:<\/strong> Refina produtos petrol\u00edferos, trata a lama de perfura\u00e7\u00e3o de campos petrol\u00edferos e extrai alumina da bauxite (processo Bayer).<\/p>\n

Tratamento da \u00e1gua:<\/strong> Ajusta o pH, neutraliza as \u00e1guas residuais \u00e1cidas e remove metais pesados.<\/p>\n

Ind\u00fastria alimentar:<\/strong> O NaOH de qualidade alimentar \u00e9 utilizado para a limpeza de equipamentos e para a regula\u00e7\u00e3o do pH (em conformidade com as normas de seguran\u00e7a alimentar).<\/p>","protected":false},"excerpt":{"rendered":"
