Copper bars are a high current conductive product suitable for high and low voltage electrical appliances, switch contacts, and distribution equipment. Electrical engineering such as bus ducts. Copper busbar, also known as copper busbar, follows the quality requirements of GB/T 5585.1-2005 standard/60364-5-523. Due to its superior conductivity to aluminum, copper bars have been widely used in electrical equipment, especially in complete power distribution devices. Generally, copper bars are used for the A, B, C, N phase busbar and PE busbar in the distribution cabinet. Copper bars are mainly used on primary lines. High current phase lines, zero lines, and ground wires all use copper bars. Copper bars are used for the connection of high current primary components on electrical cabinets.

Enamelled round aluminum wire is one of the main types of electromagnetic wire. It consists of bare wire which is annealed and softened by conductor and insulating layer, and then after repeated spraying and baking. But to meet the standard requirements of production, but also to meet customer requirements of the product is not easy, it is affected by raw material quality, processing parameters, production equipment and environmental factors, therefore, all kinds of enamoured wire quality characteristics are not the same, but have high temperature resistance, mechanical properties, electrical properties and chemical Chemical performance and excellent freezing resistance, suitable for long-term work at 200℃ and chemical invasion of freezing equipment. Corroded electrical equipment, dry type transformer, oil immersed transformer and epoxy pouring transformer and other mechanical and electrical equipment.

如何從色香味形看中藥飲片質(zhì)量?
發(fā)布時間:2023-03-21     閱讀數(shù):666    來源:

為了提高中藥飲片質(zhì)量,則應(yīng)該遵守科學(xué)的規(guī)范標(biāo)準(zhǔn),嚴(yán)格按照《中藥飲片炮制規(guī)范》炮制各種中藥飲片。下面河北全泰藥業(yè)有限公司給大家講講如何從色香味形看中藥飲片質(zhì)量?

? ? ? ?1、【色】各種藥材的顏色是不同的,藥材因加工或貯藏不當(dāng),就會改變其固有的色澤。藥材的顏色是否符合要求,是衡量藥材質(zhì)地好壞的重要因素。如果外觀色澤改變,往往意味著它的化學(xué)成分及臨床療效都有改變,如大黃、黃連變黑,黃芩變綠,荊芥、薄荷變黯,白芍泛紅等,都是質(zhì)變的標(biāo)志。炮制可改變飲片的顏色,炒焦品表面呈焦黃色,炒炭后表面焦黑色,內(nèi)部焦黃色,若內(nèi)外全黑即為不合格。飲片變色多與藥材傷水、火燥不及時、炮制不當(dāng)、貯藏日久、蟲蛀生霉、經(jīng)常日曬等有關(guān)。

? ? ? ?2、【香】各種藥物固有的氣味,是鑒別真?zhèn)蝺?yōu)劣的依據(jù)之一,如魚腥草具魚腥氣,白鮮皮具羊膻氣,香加皮具濃厚的香氣可與地骨皮區(qū)別。種子類藥材炮制時,要炒至鼓起有香氣溢出為合格。有的藥物貯存過程中,有效成分會逐漸揮發(fā)散失,香氣變淡,用到臨床也會影響療效,麝香密封陰涼干燥處保存就是這個道理,薄荷、荊芥、細辛年久失氣則療效下降。所以要加快藥材流通,減少貯存時間,保持藥材的新鮮度。

? ? ? ?3、【味】藥材的味道與本身含有的成分有關(guān),也是衡量品質(zhì)的標(biāo)準(zhǔn)之一,如烏梅、木瓜、山楂以酸為佳,黃連、黃柏以苦為佳,甘草、黨參以甜為佳,蓽茇以辛辣為佳,辣味可以幫助鑒別海風(fēng)屯與青風(fēng)屯,生半夏、生天南星辛辣、麻舌、刺喉、忌口嘗,炮制標(biāo)準(zhǔn)以味淡、不麻舌為合格。

? ? ? ?4、【形】形指形狀、大小、厚薄等,也是影響療效的一個重要因素。加工的中藥飲片很多不合格,主要是形偏大、偏厚,段偏長,調(diào)劑不方便,影響成分煎出。
