style="text-indent:25px">【正盟環(huán)?！繜o松香型免清洗助焊劑是采用無鹵素、無松香和合成樹脂以及新型活性劑的體系。無松香、無鹵素的免清洗型助焊劑主要由活化劑、溶劑、成膜物和抗氧化熱穩(wěn)定劑組成。溶劑選用高沸點醇和低沸點醇的混合物；活化劑選用有機酸和有機胺的混合物；成膜物選用合成高分子樹脂材料，這類物質(zhì)具有良好的電氣性能，常溫下起保護膜作用不顯活性，在200℃~300℃的焊接溫度下顯示活性。硅改性丙烯酸樹脂具有無腐蝕、防潮及三防性能優(yōu)異的特點，可將其作為成膜劑。另外選用抗氧化熱穩(wěn)定劑對苯二酚、保護劑苯駢三氮唑作為輔助成分。如以已二酸、癸二酸、苯駢三氮唑為活性成分，乙二醇單丁醚、乙醇、異丁醇為溶劑，美國托馬思兩性活性劑、碳氟離子表面活性劑、快速滲透劑OT為特殊成分的低固含量免清洗助焊劑。</p><p style="text-indent:25px">【正盟環(huán)保】常用的焊料錫（Sn），是銀白色、有光澤、有延展性、呈脆性、在空氣中不易氧化的金屬，熔點為232℃。由于純錫，呈脆性，并且能與大多數(shù)金屬熔融形成合金，因此為了讓以錫為主的焊料具有韌性，同時降低熔點，必須與另外一種金屬熔融，以改善錫焊料的焊接性能。鉛（Pb），是青灰色、質(zhì)軟、密度大、有延展性、有毒性、在空氣中易氧化的金屬，熔點為327℃。但是鉛，是一種不錯的錫焊料添加料，當與錫按比例熔融混合后，就得到常用的‘含鉛焊錫料’。這種‘含鉛錫焊料’，熔點變低，利于低溫焊接，能容易與大多數(shù)金屬結(jié)合（即：容易上焊料），并且價格低、導電性好、焊點可靠。生產(chǎn)水基環(huán)保免清洗焊劑、光伏組件助焊劑廠家。</p><div

style="text-indent:25px">【正盟環(huán)?！恐竸┏煞?近幾十年來，在電子產(chǎn)品生產(chǎn)錫焊工藝過程中，一般多使用主要由松香、樹脂、含鹵化物的活性劑、添加劑和有機溶劑組成的松香樹脂系助焊劑.這類助焊劑雖然可焊性好，成本低，但焊后殘留物高.其殘留物含有鹵素離子，會逐步引起電氣絕緣性能下降和短路等問題，要解決這一問題，必須對電子印制板上的松香樹脂系助焊劑殘留物進行清洗.這樣不但會增加生產(chǎn)成本，而且清洗松香樹脂系助焊劑殘留的清洗劑主要是氟氯化合物.這種化合物是大氣臭氧層的損耗物質(zhì)，屬于禁用和被淘汰之列.仍有不少公司沿用的工藝是屬于前述采用松香樹指系助焊劑焊錫再用清洗劑清洗的工藝，效率較低而成本偏高。正盟環(huán)保生產(chǎn)環(huán)保助焊劑，品質(zhì)可靠，可加工。紹興助焊劑危害</p><p

style="text-indent:25px">【正盟環(huán)?！繕渲盗兄竸?在電子產(chǎn)品的焊接中使用比例較大的是樹脂型助焊劑。由于它只能溶解于有機溶劑，故又稱為有機溶劑助焊劑，其主要成分是松香。松香在固態(tài)時呈非活性，只有液態(tài)時才呈活性，其熔點為127℃活性可以持續(xù)到315℃。錫焊的溫度為240～250℃，所以正處于松香的活性溫度范圍內(nèi)，且它的焊接殘留物不存在腐蝕問題，這些特性使松香為非腐蝕性焊劑而被廣泛應用于電子設(shè)備的焊接中。為了不同的應用需要，松香助焊劑有液態(tài)、糊狀和固態(tài)3種形態(tài)。固態(tài)的助焊劑適用于烙鐵焊，液態(tài)和糊狀的助焊劑分別適用于波峰焊。紹興助焊劑危害</p><p
