塑料焊接

1．熔接(jie)法：超聲波振動(dong)隨焊頭(tou)將超聲波傳導至焊件(jian)，由于兩焊件(jian)處聲阻(zu)大，因此(ci)產(chan)生(sheng)局部高溫，使(shi)焊件(jian)交界面(mian)熔化。在(zai)一定壓力下，使(shi)兩焊件(jian)達到(dao)美(mei)觀、快速、堅固(gu)的熔接(jie)效(xiao)果。

2．埋(mai)植(zhi)(插)法(fa)：螺母或其它金(jin)(jin)(jin)屬欲插入塑料工(gong)件。首先將(jiang)超聲波傳(chuan)至金(jin)(jin)(jin)屬，經(jing)高(gao)速振動，使金(jin)(jin)(jin)屬物直接埋(mai)入成(cheng)型塑膠內，同時將(jiang)塑膠熔化，其固化后完(wan)成(cheng)埋(mai)插。

3．鉚接法：欲將(jiang)金屬和塑料或兩塊(kuai)性(xing)質不同的塑料接合起來，可(ke)利用超聲波(bo)鉚接法，使焊件不易脆化、美觀、堅固(gu)。

4．點(dian)焊(han)法(fa)：利用小型(xing)焊(han)頭將兩件(jian)大型(xing)塑(su)料制品分點(dian)焊(han)接，或整排齒狀的焊(han)頭直接壓于兩件(jian)塑(su)料工件(jian)上，從而達到點(dian)焊(han)的效(xiao)果。

5．成(cheng)型法：利用超聲波將(jiang)塑(su)料(liao)(liao)工(gong)件瞬間(jian)熔化成(cheng)型，當塑(su)料(liao)(liao)凝(ning)固(gu)時(shi)可使(shi)金屬(shu)或其它(ta)材質的(de)塑(su)料(liao)(liao)牢(lao)固(gu)。

6．切除(chu)法：利用焊頭及底座的特(te)別設計方式，當塑(su)料(liao)工件剛射出時，直接壓于(yu)塑(su)料(liao)的枝干(gan)上，通過超聲(sheng)波傳導達(da)到切除(chu)的效果。超聲(sheng)波處理可以用于(yu)材料(liao)的檢測(ce)和分析，如厚度測(ce)量、缺陷檢測(ce)等。江(jiang)蘇供(gong)應超聲(sheng)波處理報價

超聲除螨

科研(yan)人員(yuan)發(fa)現，螨蟲的(de)(de)(de)(de)聽覺神(shen)經系(xi)統(tong)很脆弱，對特(te)定頻(pin)率的(de)(de)(de)(de)超(chao)聲(sheng)(sheng)非常敏感(gan)，針對螨蟲的(de)(de)(de)(de)這(zhe)種生(sheng)理(li)(li)特(te)性，已有科技公(gong)司的(de)(de)(de)(de)研(yan)究人員(yuan)開發(fa)出(chu)了超(chao)聲(sheng)(sheng)波除螨儀。這(zhe)種新(xin)型(xing)的(de)(de)(de)(de)除螨產品(pin)(pin)采(cai)用現代微電子技術手段，直接用特(te)殊頻(pin)率的(de)(de)(de)(de)超(chao)聲(sheng)(sheng)作用于螨蟲的(de)(de)(de)(de)聽覺神(shen)經系(xi)統(tong)，使其(qi)生(sheng)理(li)(li)系(xi)統(tong)紊亂，煩(fan)躁(zao)不安，食(shi)欲(yu)不振，**終奄(yan)奄(yan)一息(xi)逐(zhu)漸死亡。采(cai)用這(zhe)種原理(li)(li)的(de)(de)(de)(de)除螨產品(pin)(pin)不用添加任何化(hua)學藥劑(ji)，無毒(du)無二次污染，對人體和家中寵物都沒(mei)有傷害，是比較理(li)(li)想的(de)(de)(de)(de)除螨產品(pin)(pin)。湖(hu)北超(chao)聲(sheng)(sheng)波處理(li)(li)超(chao)聲(sheng)(sheng)波在(zai)食(shi)品(pin)(pin)加工行業中可用于殺菌、脫水(shui)、分(fen)離(li)等方面。

超(chao)(chao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)(bo)在媒質中(zhong)的(de)(de)(de)反射(she)、折射(she)、衍射(she)、散射(she)等傳(chuan)播(bo)(bo)規律，與(yu)可聽聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)(bo)的(de)(de)(de)規律沒有本質上的(de)(de)(de)區別。但是(shi)超(chao)(chao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)(bo)的(de)(de)(de)波(bo)(bo)(bo)(bo)(bo)長(chang)很(hen)短，只(zhi)有幾厘米(mi)，甚(shen)至千(qian)分(fen)之幾毫米(mi)。與(yu)可聽聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)(bo)比較(jiao)，超(chao)(chao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)(bo)具(ju)有許(xu)多奇異特(te)性：傳(chuan)播(bo)(bo)特(te)性──超(chao)(chao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)(bo)的(de)(de)(de)波(bo)(bo)(bo)(bo)(bo)長(chang)很(hen)短，通(tong)常的(de)(de)(de)障礙物(wu)的(de)(de)(de)尺寸要(yao)比超(chao)(chao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)(bo)的(de)(de)(de)波(bo)(bo)(bo)(bo)(bo)長(chang)大好多倍，因此超(chao)(chao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)(bo)的(de)(de)(de)衍射(she)本領很(hen)差，它(ta)在均勻介質中(zhong)能夠定向直線傳(chuan)播(bo)(bo)，超(chao)(chao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)(bo)的(de)(de)(de)波(bo)(bo)(bo)(bo)(bo)長(chang)越(yue)短，該特(te)性就越(yue)。功率(lv)特(te)性──當聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)音在空(kong)(kong)氣中(zhong)傳(chuan)播(bo)(bo)時，推(tui)動空(kong)(kong)氣中(zhong)的(de)(de)(de)微粒往復振動而對(dui)微粒做功。聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)(bo)功率(lv)就是(shi)表(biao)示聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)(bo)做功快慢的(de)(de)(de)物(wu)理量。在相(xiang)同強度下(xia)，聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)(bo)的(de)(de)(de)頻率(lv)越(yue)高，它(ta)所具(ju)有的(de)(de)(de)功率(lv)就越(yue)大。

③熱效應。由于超聲波(bo)頻率高，能量大，被(bei)介質吸收時能產生的熱效應。

④化(hua)(hua)學(xue)效應(ying)(ying)。超(chao)聲波(bo)的(de)(de)作(zuo)用(yong)(yong)可促使(shi)發(fa)生(sheng)或加速(su)某些(xie)(xie)化(hua)(hua)學(xue)反應(ying)(ying)。例(li)如純的(de)(de)蒸(zheng)餾水經超(chao)聲處(chu)理(li)后(hou)產(chan)生(sheng)過氧化(hua)(hua)氫；溶有(you)氮(dan)氣的(de)(de)水經超(chao)聲處(chu)理(li)后(hou)產(chan)生(sheng)亞硝(xiao)酸；染料的(de)(de)水溶液經超(chao)聲處(chu)理(li)后(hou)會變色或退色。這些(xie)(xie)現(xian)象的(de)(de)發(fa)生(sheng)總與(yu)空(kong)化(hua)(hua)作(zuo)用(yong)(yong)相伴隨。超(chao)聲波(bo)還可加速(su)許(xu)多化(hua)(hua)學(xue)物質的(de)(de)水解(jie)、分解(jie)和聚合過程(cheng)。超(chao)聲波(bo)對光(guang)化(hua)(hua)學(xue)和電化(hua)(hua)學(xue)過程(cheng)也有(you)明(ming)顯影響。各種氨基酸和其他有(you)機物質的(de)(de)水溶液經超(chao)聲處(chu)理(li)后(hou)，特征吸(xi)(xi)收光(guang)譜帶消(xiao)失而呈(cheng)均勻的(de)(de)一般吸(xi)(xi)收，這表明(ming)空(kong)化(hua)(hua)作(zuo)用(yong)(yong)使(shi)分子結構發(fa)生(sheng)了改變。超(chao)聲波(bo)處(chu)理(li)技(ji)術在GF、航空(kong)航天等領域具有(you)重要(yao)戰略意義。

超聲效(xiao)應(ying)：當超聲波(bo)在(zai)介(jie)質中傳(chuan)播時，由于超聲波(bo)與(yu)介(jie)質的相互作用，使介(jie)質發生(sheng)(sheng)變(bian)化，從而產生(sheng)(sheng)一系(xi)列(lie)力學(xue)的、電磁學(xue)的超聲效(xiao)應(ying)，包括(kuo)以下(xia)兩種效(xiao)應(ying)：

①機械(xie)(xie)效應。超(chao)(chao)聲(sheng)(sheng)波(bo)(bo)的機械(xie)(xie)作用可(ke)促(cu)成(cheng)(cheng)液體(ti)的乳化、凝膠(jiao)的液化和(he)固體(ti)的分散。當超(chao)(chao)聲(sheng)(sheng)波(bo)(bo)流(liu)(liu)體(ti)介質中(zhong)形成(cheng)(cheng)駐波(bo)(bo)時，懸浮在(zai)(zai)流(liu)(liu)體(ti)中(zhong)的微小顆粒因(yin)受(shou)機械(xie)(xie)力(li)的作用而凝聚在(zai)(zai)波(bo)(bo)節處(chu)，在(zai)(zai)空間(jian)形成(cheng)(cheng)周(zhou)期(qi)性(xing)的堆積。超(chao)(chao)聲(sheng)(sheng)波(bo)(bo)在(zai)(zai)壓電材(cai)料和(he)磁致伸縮材(cai)料中(zhong)傳播(bo)時，由于(yu)超(chao)(chao)聲(sheng)(sheng)波(bo)(bo)的機械(xie)(xie)作用而引(yin)起的感生電極化和(he)感生磁化。

②空(kong)(kong)化(hua)作(zuo)用(yong)(yong)。超聲(sheng)波(bo)(bo)作(zuo)用(yong)(yong)于(yu)液(ye)體時(shi)可產(chan)生大(da)量小氣泡(pao)(pao)。一(yi)個原(yuan)因是液(ye)體內局部出(chu)現拉(la)應力而形成(cheng)負壓，壓強(qiang)的(de)(de)(de)降低使原(yuan)來溶(rong)于(yu)液(ye)體的(de)(de)(de)氣體過飽和(he)，而從(cong)液(ye)體逸出(chu)，成(cheng)為小氣泡(pao)(pao)。另(ling)一(yi)原(yuan)因是強(qiang)大(da)的(de)(de)(de)拉(la)應力把液(ye)體“撕開”成(cheng)一(yi)空(kong)(kong)洞，稱為空(kong)(kong)化(hua)。空(kong)(kong)洞內為液(ye)體蒸氣或溶(rong)于(yu)液(ye)體的(de)(de)(de)另(ling)一(yi)種(zhong)氣體，甚至(zhi)可能是真空(kong)(kong)。因空(kong)(kong)化(hua)作(zuo)用(yong)(yong)形成(cheng)的(de)(de)(de)小氣泡(pao)(pao)而不斷長大(da)或突然破滅(mie)。破滅(mie)時(shi)周圍液(ye)體突然沖(chong)入氣泡(pao)(pao)而產(chan)生高壓，同時(shi)產(chan)生激波(bo)(bo)。與(yu)(yu)空(kong)(kong)化(hua)作(zuo)用(yong)(yong)相(xiang)伴隨的(de)(de)(de)內摩擦可形成(cheng)電(dian)荷，并在氣泡(pao)(pao)內因放電(dian)而產(chan)光現象。在液(ye)體中進行超聲(sheng)處理(li)的(de)(de)(de)技術大(da)多與(yu)(yu)空(kong)(kong)化(hua)作(zuo)用(yong)(yong)有(you)關。江蘇供應超聲(sheng)波(bo)(bo)處理(li)報價
