医药用碳酸氫鈉(小苏打)用量很大,近来货源較为紧張,为了滿足医疗需要,我厂在党和行政的鼓励和支持下,进行試制,克服种种困难,經过多次試制,終于成功。現已投入生产,經檢查和含量测定,純度达到99.8%以上。制造过程: 原料:純碱(炭酸鈉),石灰石,煤炭,水。爐灶(附图)是外用火磚,內用黄泥和炭渣食盐等建成,爐桥是活的。先將引火物如木塊和易燃的东西置于爐桥上面,再上煤炭約全部煤炭的五分之一,然后將石灰石与煤(無烟塊煤)按1:1或1:2分层裝于爐內,裝至达通气管下半尺之处为止。此时在爐桥下面將引火物点燃,至全部煤炭、石灰石燃紅,將盖(用铁锅)盖好,並用沙將盖周圍空隙处封閉好,不使气体跑出。此时爐内的二氧化碳气体經过气管进入洗滌塔庥没鸫u內用洋灰建成,上面有加水管(头用雨栅或用洒水壶头),下有龙头並与进气管相平,二氧化碳气体經此塔洗滌后便进入反应室?从κ矣没鸫u建成,頂上角留有小活门,并有3—5个气洞,側面留有门夷谏栌卸嗖慵?用木制成,上編有竹帘,將碳酸鈉加10—15%水潤湿,调合均匀置木架上,架上铺有紗布。第一层架铺的碳酸鈉层在右边留少許空隙,第二层在
The amount of sodium bicarbonate (baking soda) used in medicine is very large, and the supply has been tight recently. In order to meet the medical needs, our factory has carried out trial production under the encouragement and support of the party and the administration to overcome various difficulties, and after several trial productions, Finally succeeded. Now it has been put into production. After inspection and content determination, the purity has reached 99.8%. Manufacturing process: Raw materials: soda ash (sodium carbonate), limestone, coal, water. The stoves (drawings) are external fire bricks, built with yellow mud and carbon residue salt, etc. The furnace bridge is alive. First place firelight objects such as wooden blocks and flammable things on the top of the furnace bridge, and then add about one-fifth of coal to all coal, and then press limestone and coal (non-smoking lump coal) at 1:1 or 1:2 The layers are installed in the furnace and installed up to half a foot of the vent pipe. At this time, the firelighters are ignited below the furnace bridge, until all coal and limestone burn red, the lid is covered (with a wok), and the gap around the lid is closed with sand so that no gas escapes. At this time, the carbon dioxide gas in the furnace enters the scrubbing tower through the gas pipe, and is built with cement dust. There is a water pipe (head with a rain grate or a watering can head) above the gas pipe, and there is a faucet and a level with the intake pipe. After the carbon dioxide gas is washed in this tower, it enters the reaction chamber. It is built from κ矣, and there are small traps on the top corner, and there are 3-5 gas holes. Made of bamboo blinds, add 10-15% water to wet the sodium carbonate, mix evenly on a wooden stand, and spread gauze on the rack. The first layer of sodium carbonate lays a little space on the right, and the second layer
