Rov qab-siab nyhuv:
Qee yam khoom siv (xws li quartz, piezoelectric ceramics, thiab lwm yam), thaum raug rau sab nraud quab yuam, tsis tsuas yog hloov lawv cov duab qhov ntev, tab sis kuj sab hauv polarize, thiab muaj nqi nyob rau saum npoo los tsim hluav taws xob teb; thaum lub zog sab nraud ploj, cov khoom xa rov qab mus rau nws lub xeev qub, Qhov tshwm sim no hu ua cov nyhuv piezoelectric; Ntawm qhov tsis sib xws, yog tias cov tshuaj no tau muab tso rau hauv hluav taws xob teb, lawv qhov ntev geometric kuj hloov.Qhov qhov tshwm sim ntawm kev hloov kho tshuab ntawm cov tshuaj vim qhov kev txiav txim ntawm ib qho hluav taws xob sab nraud tau hu ua qhov cuam tshuam piezoelectric effect.
Ultrasonic ua thiab Ultrasonic Lace Txiav Machine yog txhua daim ntawv thov ntawm cov nyhuv piezoelectric.
◆ Cov Hauv Paus:
Qhov ntsuas ultrasonic ntawm lub tshuab ultrasonic lace tau muab faib ua ob qho loj, ib lub tshuab hluav taws xob ultrasonic thiab tshuab ultrasonic transducer, raws li qhia hauv daim duab hauv qab no.

Cov ultrasonic transducer system muaj li ntawm ultrasonic transducer, tshuab raj thiab lub tshuab raj tshuab raj. Thaum 220V, 50Hz fais fab zaus AC tam sim no nkag mus rau ultrasonic lub tshuab hluav taws xob, lub tshuab hluav taws xob pib ua haujlwm, hloov 50Hz zaus rau 20000Hz, thiab khaws nws ntawm qhov zaus no. Qhov 20000Hz tawm tam sim no los ntawm lub tshuab hluav taws xob ultrasonic ntws mus rau hauv lub transducer, thiab lub tshuab hloov pauv hloov hluav taws xob lub zog rau hauv kev siv zog los tsim lub tshuab hluav taws xob ultrasonic kev txiav tawm mus rau nws sab saud, qhov ntau ntawm tsuas yog 0.005 ～ 0.01mm, thiab tom qab ntawd qhov nrawm ntawm kub thiab lub cuab tam tau hloov pauv. Tus pas nrig yog nthuav dav los ntawm 0.05 mus rau 0.1mm, thiab lub ntsej muag kawg ntawm lub cuab yeej tsav tsheb yog ultrasonically vibrated. Muaj lub paj log ntawm sab saud lub cuab tam. Thaum cov ntaub yog nias nruab nrab ntawm lub paj log thiab lub ntsej muag kawg ntawm lub cuab yeej tshuab raj, Los ntawm kev sib txhuam ntawm qhov chaw tiv tauj thiab nruab nrab ntawm cov ntsuas, qhov kub ntawm qhov chaw sib chwv nce siab, thiab txiav (qhov siab tshaj plaws ntawm lub paj log) , perforation (qhov siab tshaj plaws ntawm lub paj log) lossis embossing (qhov thib ob siab tshaj plaws ntawm lub paj log) tshwm sim.
