有鉛焊錫絲和無鉛焊錫絲的對比 - 綠誌島—領先綠色科技

        有鉛焊錫絲和(he)無(wu)鉛(qian)焊(han)錫(xi)絲(si)是(shi)兩(liang)大(da)類(lei)不(bu)同(tong)的(de)焊(han)錫(xi)材(cai)料(liao)，有(you)鉛(qian)焊(han)錫(xi)絲(si)和(he)無(wu)鉛(qian)焊(han)錫(xi)絲(si)的(de)區(qu)別(bie)在(zai)於(yu)它(ta)們(men)的(de)金(jin)屬(shu)成(cheng)分(fen)不(bu)同(tong)
，所(suo)以(yi)合(he)金(jin)熔(rong)點(dian)也(ye)不(bu)同(tong)
，合(he)金(jin)成(cheng)分(fen)最(zui)明(ming)顯(xian)的(de)不(bu)同(tong)，從(cong)兩(liang)者(zhe)的(de)名(ming)稱(cheng)就(jiu)能(neng)知(zhi)道(dao)，一(yi)個(ge)含(han)鉛(qian)一(yi)個(ge)不(bu)含(han)鉛(qian)。無(wu)鉛(qian)焊(han)錫(xi)絲(si)其(qi)實(shi)並(bing)不(bu)是(shi)真(zhen)的(de)一(yi)點(dian)鉛(qian)金(jin)屬(shu)也(ye)沒(mei)有(you)
，隻(zhi)是(shi)含(han)鉛(qian)量(liang)非(fei)常(chang)低(di)，達(da)到(dao)國(guo)際(ji)環(huan)保(bao)要(yao)求(qiu)
，所(suo)以(yi)才(cai)稱(cheng)之(zhi)為(wei)環(huan)保(bao)無(wu)鉛(qian)焊(han)錫(xi)絲(si)。

        有鉛焊錫絲的熔點是183℃
，無鉛焊錫絲的熔點較高為227℃左zuo右you，含han鉛qian量liang的de多duo少shao決jue定ding了le焊han錫xi絲si熔rong點dian的de高gao低di。除chu熔rong點dian影ying響xiang焊han錫xi質zhi量liang外wai，需xu配pei合he焊han錫xi絲si使shi用yong的de助zhu焊han劑ji也ye是shi影ying響xiang焊han錫xi質zhi量liang的de關guan鍵jian因yin素su。焊han錫xi絲si熔rong化hua後hou助zhu焊han劑ji決jue定ding金jin屬shu的de活huo性xing，如ru果guo焊han錫xi絲si的de熔rong點dian過guo高gao，那na麼me助zhu焊han劑ji的de揮hui發fa速su度du就jiu會hui加jia快kuai

，焊han錫xi絲si的de流liu動dong性xing也ye會hui變bian得de不bu強qiang
，很hen容rong易yi產chan生sheng錫xi尖jian
、錫xi橋qiao和he拉la絲si等deng不bu良liang影ying響xiang。有you鉛qian焊han錫xi絲si和he無wu鉛qian焊han錫xi絲si的de可ke焊han性xing也ye有you很hen大da不bu同tong
，有you鉛qian焊han錫xi絲si相xiang對dui來lai說shuo更geng容rong易yi焊han接jie，隻zhi因yin無wu鉛qian焊han錫xi絲si中zhong錫xi含han量liang相xiang對dui較jiao高gao，進jin行xing焊han接jie操cao作zuo的de時shi間jian也ye會hui拉la長chang。
