style="text-indent:25px">【正盟環(huán)保】低松香型免清洗助焊劑是一種專為用于機(jī)器焊接高級(jí)多層電路板的助焊劑。此類助焊劑助焊能力強(qiáng)，發(fā)泡性能好，不含鹵素，在焊接時(shí)產(chǎn)生的煙霧和其殘余物對(duì)焊料和裸銅無(wú)腐蝕性，在較高的預(yù)熱溫度100℃～130℃時(shí)得到狀態(tài)。因此，它是一種較理想的免清洗助焊劑，在板子上具有極高的表面絕緣阻抗以及快干的效果，板子的粘膩感亦可以減少到低的程度，能夠輕易地通過(guò)測(cè)試程序，適用于任何高0端線路板波峰焊、噴焊及手工焊。該助焊劑中溶劑既要對(duì)焊接表面具有良好的保護(hù)作用，又要有適當(dāng)?shù)酿ざ?。高沸點(diǎn)的醇保護(hù)效果較好，但黏度大、使用不便；低沸點(diǎn)的醇黏度低，但保護(hù)性差，廣州助焊劑品牌，因而可以考慮選擇混合醇的方法，廣州助焊劑品牌。有資料表明，乙醇、乙二醇，廣州助焊劑品牌、丙三醇和乙二醇丁醚的配比(質(zhì)量比)為2:8:8:1的混合溶劑效果上佳。買助焊劑認(rèn)準(zhǔn)正盟牌。廣州助焊劑品牌</p><div

①提高經(jīng)濟(jì)效益：實(shí)現(xiàn)免清洗后，直接的就是不必進(jìn)行清洗工作，因此可以大量節(jié)約清洗人工、設(shè)備、場(chǎng)地、材料（水、溶劑）和能源的消耗，同時(shí)由于工藝流程的縮短，節(jié)約了工時(shí)提高了生產(chǎn)效率。 ②提高產(chǎn)品質(zhì)量：由于免清洗技術(shù)的實(shí)施，要求嚴(yán)格控制材料的質(zhì)量，如助焊劑的腐蝕性能（不允許含有鹵化物）、元器件和印制電路板的可焊性等；在裝聯(lián)過(guò)程中，需要采用一些先進(jìn)的工藝手段，如噴霧法涂敷助焊劑、在惰性氣體保護(hù)下焊接等。實(shí)施免清洗工藝，可避免清洗應(yīng)力對(duì)焊接組件的損傷，因此免清洗對(duì)提高產(chǎn)品質(zhì)量是極為有利的。 ③有利于環(huán)境保護(hù)：采用免清洗技術(shù)后，可停止使用ODS物質(zhì)，也大幅度地減少了揮發(fā)性有機(jī)物（VOC）的使用，從而對(duì)保護(hù)臭氧層具有積極作用。湖州生產(chǎn)助焊劑環(huán)保級(jí)助焊劑，可免除清洗工序，進(jìn)而節(jié)約制造商的生產(chǎn)費(fèi)用和工作時(shí)間。</p><div
