Traditional cleaning industrial equipment has a variety of cleaning methods, mostly using chemical agents and mechanical methods. With the increasingly strict requirements of China's environmental protection laws and regulations and the increasing awareness of people's environmental protection and safety, the types of chemicals that can be used in industrial production cleaning will become less and less. Laser cleaning has the characteristics of no grinding, non-contact, low heat effect and suitable for all kinds of objects.
Ishlov beriladigan qism yuzasidagi ifloslantiruvchi moddalar orasida ishlov beriladigan buyum yuzasidagi biriktirma va sirt o'rtasidagi birikma asosan quyidagi kuchlarga bog'liq. Ularning orasida kapillyar kuch, adsorbsiya kuchi va elektrostatik kuchni yo'q qilish eng qiyin, shuning uchun lazerni tozalash bu kuchlarni engish kerak. Zarrachalarning o'lchamlari qanchalik kichik bo'lsa, ularni olib tashlash uchun zarur bo'lgan tezlashuv shunchalik katta bo'ladi, shuning uchun an'anaviy tozalash texnologiyasi kichik diametrli ob'ektlarning sirt qo'shimchalarini olib tashlash qiyin.
Xitoyda lazerni tozalash texnologiyasini tadqiq qilish va asbob-uskunalarni ishlab chiqish kech boshlandi, asosan xorijiy mamlakatlarning rivojlanishini kuzatib bordi. Qisqa vaqt ichida ma’lum yutuqlarga erishilgan bo‘lsa-da, xorijiy davlatlar bilan solishtirganda sezilarli bo‘shliq bor. Shuning uchun, Xitoyda etuk lazer tozalash uskunalari ko'p emas. Bundan tashqari, tozalash samaradorligi va barqarorligini oshirish juda muhimdir.
Lazerli tozalash texnologiyasini tadqiq qilish 1980-yillarning o'rtalarida boshlangan, ammo u 1990-yillarning boshlariga qadar sanoat ishlab chiqarishiga kirmagan. Ko'p hollarda u asta-sekin an'anaviy tozalash usullarini almashtiradi. Xorijiy mamlakatlarda lazerni tozalashning zararsizlantirish diapazoni juda keng, qalin zang qatlamidan lazer yuzasida nozik zarrachalargacha olib tashlanishi mumkin. Zararsizlantirishda lazerni tozalash tajribalarida ishlatiladigan ko'plab turdagi uskunalar mavjud va ishlatiladigan lazerning to'lqin uzunligi keng. Biroq, lazerni tozalash texnologiyasining rivojlanishi notekis. Ba'zilari sanoatlashtirishda etakchi o'rinni egalladi, boshqalari esa hali ham laboratoriya bosqichida.
The emergence of laser cleaning technology has opened up a new field of industrial application of laser technology. Using China's existing laser technology conditions, supporting laser cleaning equipment has been developed. And make it practical in a short time. Industrialization. It is entirely possible and of great significance to promote the development of high-tech industries.
