&nbsp; &nbsp;纯碱的用途:&nbsp; 1.绝大部分用于工业,一小部分为民用。在工业用纯碱中,主要是轻工、建材、化学工业,约占2/3:其次是冶金、纺织、石油、国防、医药及其他工业。玻璃工业是纯碱消费部门,每吨玻璃消耗纯碱0.2t。化学工业用于制水玻璃、氟化钠、小苏打、硼砂、磷酸三钠等。冶金工业用作冶炼助熔剂、选矿用浮选剂,炼钢和炼锑用作脱硫剂。印染工业用作软水剂。制革工业用于原料皮的脱脂、中和铬鞣革和提高铬鞣液碱度。还用于生产合成洗涤剂添加剂三聚磷酸钠和其他磷酸钠盐等。&nbsp; 2.主要用于浮法玻璃、显像管玻壳、光学玻璃等。也可用于化工、冶金等其他部门。使用重质纯碱可以减少碱尘飞扬、降低原料消耗、改善劳动条件,还可提高产品质量,同时减轻碱粉对耐火材料的侵蚀作用,延长窑炉的使用寿命。&nbsp; 3.作缓冲剂、中和剂和面团改良剂,可用于糕点和面制食品,按生产需要适量使用。&nbsp; 4.基本化工原料,广泛用于造纸、冶金、玻璃、纺织、染料等工业。&nbsp; 5.作为洗涤剂用于羊毛漂洗,浴盐和医药用,鞣革中的碱剂。&nbsp; 6.用于食品工业,作中和剂、膨松剂,如制造氨基酸、酱油和面制食品如馒头、面包等。还可配成碱水加入面食中,增加弹性和延展性。&nbsp; 7.彩电专用试剂&nbsp; 8.广泛用于玻璃制品、化学品、造纸、冶金、医药、纺织和食品等工业&nbsp; 9.用作分析试剂,也用于制药工业和照相制版&nbsp; 10.无水碳酸钠用于化学及电化学除油、化学镀铜、铝的浸蚀、铝及合金的电解抛光、铝的化学氧化、磷化后的封闭、工序间的防锈、电解退除铬镀层和退除铬的氧化膜等,亦用于预镀铜、镀钢、镀钢铁合金电解液中&nbsp; 11.基本化工原料之一,用途广泛,是玻璃、肥皂、洗涤剂、纺织、制革、香料、染料、药品等的重要原料&nbsp; 12.定量分析中标定酸液的基准。测定铝、硫、铜、铅和锌。检验尿液和全血葡萄糖。分析水泥中二氧化硅的助溶剂。金属金相分析等&nbsp; 13.解酸药、渗透性轻泻剂。&nbsp;<img src="纯碱" style="max-width: 100%;">&nbsp;<!-- /* Font Definitions */ @font-face {font-family:宋体; panose-1:2 1 6 0 3 1 1 1 1 1; mso-font-alt:SimSun; mso-font-charset:134; mso-generic-font-family:auto; mso-font-pitch:variable; mso-font-signature:3 680460288 22 0 262145 0;} @font-face {font-family:"Cambria Math"; panose-1:2 4 5 3 5 4 6 3 2 4; mso-font-charset:0; mso-generic-font-family:roman; mso-font-pitch:variable; mso-font-signature:-536870145 1107305727 0 0 415 0;} @font-face {font-family:"\@宋体"; panose-1:2 1 6 0 3 1 1 1 1 1; mso-font-charset:134; mso-generic-font-family:auto; mso-font-pitch:variable; mso-font-signature:3 680460288 22 0 262145 0;} @font-face {font-family:Tahoma; panose-1:2 11 6 4 3 5 4 4 2 4; mso-font-charset:0; mso-generic-font-family:swiss; mso-font-pitch:variable; mso-font-signature:-520081665 -1073717157 41 0 66047 0;} /* Style Definitions */ p.MsoNormal, li.MsoNormal, div.MsoNormal {mso-style-unhide:no; mso-style-qformat:yes; mso-style-parent:""; margin:0cm; margin-bottom:.0001pt; text-align:justify; text-justify:inter-ideograph; mso-pagination:none; font-size:10.5pt; mso-bidi-font-size:12.0pt; font-family:"Times New Roman","serif"; mso-fareast-font-family:宋体; mso-font-kerning:1.0pt;} span.apple-converted-space {mso-style-name:apple-converted-space; mso-style-unhide:no;} .MsoChpDefault {mso-style-type:export-only; mso-default-props:yes; font-size:10.0pt; mso-ansi-font-size:10.0pt; mso-bidi-font-size:10.0pt; mso-ascii-font-family:"Times New Roman"; mso-fareast-font-family:宋体; mso-hansi-font-family:"Times New Roman"; mso-font-kerning:0pt;} /* Page Definitions */ @page {mso-page-border-surround-header:no; mso-page-border-surround-footer:no;} @page WordSection1 {size:612.0pt 792.0pt; margin:72.0pt 90.0pt 72.0pt 90.0pt; mso-header-margin:36.0pt; mso-footer-margin:36.0pt; mso-paper-source:0;} div.WordSection1 {page:WordSection1;} -->
