Xyoo 1982 kev tso suab paj nruas "Victor Victoria," Julie Andrews hu nkauj zoo siab kawg ntawm nws tus xeeb ceem Parisian cabaret kev ua yeeb yam. Nws txhawb nqa daim ntawv thiab tsom-iav champagne ncig lub chav ua haujlwm. Qhov ci ntsa iab no tau qhia meej tias lub suab nrov nrawm lossis nrawm heev tuaj yeem tsoo cov khoom sib nrug li cas. Tab sis koj puas paub tias lub suab loj tuaj yeem siv tau los ua cov khoom siv sib txuas ua ke? Lub thev naus laus zis hu ua ultrasonic vuam yog siv los sib sau ua ke cov khoom lag luam los ntawm ntau qhov kev lag luam - xws li los ntawm cov cuab yeej siv kho mob mus rau cov kis las kis las mus rau tsheb.
Feem ntau, koj tuaj yeem khi cov khoom siv los ntawm kev siv cov khawm fasteners xws li ntsia hlau, ntsia hlau lossis xov. Qhov no yog qhov tsim nyog rau cov hlau, ntoo, ntaub thiab plastics. Rau ntau plastics, lo yog siv; cov kua nplaum ua rau cov ntawv cog lus sib txuas ntawm cov kua nplaum nws tus kheej thiab ntawm cov chaw uas muaj cov ntaub ntawv yas. Cov hlau tuaj yeem sib koom ua ke los ntawm cua sov lwm cov hlau ua cov kab mob sib khi, xws li cov hlau lead hauv cov hluav taws xob sib txuas. Hloov pauv, cov hlau tuaj yeem ncaj qha melted ua ke (welding); ib zaug melted hlau nto txias, cov hlau daim ntawv cog lus ua ke. Vuam feem ntau yuav tsum tau qhib cov nplaim hluav taws lossis tsau kom ua tiav qhov kub siab tsim nyog los ua kom cov hlau qhov chaw ua ke. Yog li, nws tuaj yeem yog tus txheej txheem kim rau qee qhov haujlwm tsim ua.
Ib qho tshiab thiab pheej yig dua vuam txheej txheem tau qhia nyob rau xyoo 1940s. Cov txheej txheem, ultrasonic vuam, siv cov loj-lub suab sib tsoo thiab cov siab ua rau cov khoom lag luam ua ke thiab yuav tsum muaj zog tsawg dua li cov pa hlau tsis sib txuas. Ultrasonic hlau txuas tsim thaum xyoo 1950 mus txog xyoo 1990 li cov khoom siv hluav taws xob siv hauv cov khoom siv tau dhau los ua ntau dua thiab cov koos pij tawj tuaj yeem tswj cov txheej txheem. Txij li lub sijhawm no, cov txheej txheem tau ua rau plastics, qhov twg nws tau ua nrov heev.
Hauv tsab xov xwm no, peb yuav saib cov khoom siv thiab cov txheej txheem lub cev ntawm ultrasonic vuam, yuav ua li cas Tshiab Tshuav tau siv nws los ua khau kis las, thiab qhov zoo thiab qhov tsis zoo ntawm cov txheej txheem no. Ua ntej, cia peb los saib kom ze li cas lub suab tsis sib txuas cov khoom siv, ob qho tib si hlau thiab yas.
