川消滅火器使用前要知道產生問題原因

對于滅火器的使用用戶來說，只能承擔滅火器配置后的檢查和維護職責，確保滅火器始終處于一種完好的使用狀態。產生質量問題的根源就在于滅火器生產企業和中介維修企業。總之，川消滅火器使用前要知道產生問題原因。
For the users of fire extinguishers, they can only undertake the inspection and maintenance responsibilities after the fire extinguishers are configured to ensure that the fire extinguishers are always in a good state of use. The root cause of quality problems lies in fire extinguisher production enterprises and intermediary maintenance enterprises. In short, we should know the cause of the problem before using Chuanxiao fire extinguishers.
原材料選定不符或控制把關不嚴
The selection of raw materials is inconsistent or the control is not strict
（1）部分不良滅火器生產企業為牟取大利潤，放松對于原材料的質量控制，ABC干粉滅火劑的含量指標一降再降，以次充好；用低含量的BC干粉滅火劑代替ABC干粉滅火劑，以假亂真；后甚采用一些滑石粉或不明粉狀物充填于滅火器內。
(1) In order to make large profits, some poor fire extinguisher manufacturers have relaxed the quality control of raw materials. The content index of ABC dry powder fire extinguishing agent has fallen again and again, and inferior fire extinguishing agents are replaced by good ones; Replace ABC dry powder fire extinguishing agent with BC dry powder fire extinguishing agent with low content to confuse the false with the true; Later, some talc powder or unknown powder was even used to fill the fire extinguisher.
（2）一些規范的滅火器生產企業在原材料選定和質量控制方面也存在疏于管理現象。特別是對于干粉滅火器的噴射機構，未能嚴格按照滅火器型式試驗時確定的噴射孔徑進行選擇和檢驗，導致干粉滅火器噴射機構的孔徑超出能保證滅火器有效噴射時間的孔徑范圍，而出現在檢查滅火器噴射性能時滅火器噴射時間短問題。
(2) Some standardized fire extinguisher production enterprises are also lax in the selection of raw materials and quality control. Especially for the injection mechanism of dry powder fire extinguishers, the selection and inspection of the injection hole diameter determined during the type test of the fire extinguisher were not strictly carried out, resulting in the hole diameter of the injection mechanism of dry powder fire extinguishers exceeding the hole diameter range that can ensure the effective injection time of the fire extinguisher, and the problem of short injection time of the fire extinguisher when checking the injection performance of the fire extinguisher occurred.
（3）為降低成本尋求利用筒體鋼板厚度標準的下偏差時失去控制，導致滅火器筒體測量壁厚小于標準規定的小壁厚值；少數不良企業甚直接以次充好，以薄代厚。近年來滅火器本身發生爆炸的案例時有發生。
(3) In order to reduce the cost, when seeking to use the lower deviation of the cylinder steel plate thickness standard, it loses control, resulting in the measured wall thickness of the fire extinguisher cylinder being less than the small wall thickness value specified in the standard; A few bad enterprises even directly shoddy, thin for thick. In recent years, the fire extinguisher itself has exploded from time to time.
滅火器生產裝配工藝質量控制不嚴
The quality control of fire extinguisher production and assembly process is not strict
（1）在滅火器檢查中發現滅火器內干粉滅火劑的充裝量少于或超出標準規定的充裝誤差范圍。滅火劑充裝得少，可以理解為生產企業為降低成本，采取不正常手段，減少滅火劑充裝量。可是對于多充怎么理解呢？這就是干粉充裝工藝控制不嚴導致的。目前國內干粉滅火劑的充裝自動計量控制裝置還不普及，并且現已使用的自動計量控制還存在計量控制不夠準確的缺陷，所以大多廠家的干粉滅火劑的充裝全靠人工操作，再加上監督校核不嚴，其精度可想可知，所以在批量生產中出現多充或少充現象。
(1) During the inspection of the fire extinguisher, it is found that the filling amount of dry powder extinguishing agent in the fire extinguisher is less than or exceeds the filling error range specified in the standard. The low filling of fire extinguishing agent can be understood as that the manufacturer adopts abnormal means to reduce the filling amount of fire extinguishing agent in order to reduce the cost. But how to understand overcharge? This is caused by the lax control of dry powder filling process. At present, the automatic metering control device for the filling of dry powder extinguishing agent in China is not popular, and the automatic metering control used now still has the defect that the metering control is not accurate enough. Therefore, the filling of dry powder extinguishing agent of most manufacturers depends on manual operation, coupled with the lax supervision and verification, its accuracy can be expected, so there is the phenomenon of overcharge or undercharge in mass production.
（2）在
川消滅火器質量檢驗中發現的滅火器噴射后內部余粉過多，噴射剩余率超出標準規定值產生的原因主要是滅火器內部的虹吸管長度不足，還有在裝配過程中干粉防潮濕性或干粉本身過潮，導致滅火器噴射時干粉的流動性不好或有結塊現象而剩余粉過多。所以選定適宜長度的虹吸管和采取有效的防潮措施可以有效減少噴射剩余率超標現象。
(2) In the quality inspection of Chuanxiao fire extinguisher, it was found that there was too much residual powder inside the fire extinguisher after spraying, and the spraying residual rate exceeded the standard specified value. The main reasons were the insufficient length of the siphon inside the fire extinguisher, and the moisture resistance of the dry powder or the excessive moisture of the dry powder itself during the assembly process, which led to the poor liquidity of the dry powder or the agglomeration of the dry powder when the fire extinguisher was sprayed, resulting in too much residual powder. Therefore, selecting siphons with appropriate length and taking effective moisture-proof measures can effectively reduce the phenomenon of excessive spraying residual rate.
