Tus electrostatic tso tawm yog dab tsi?
Ua ntej, qhov ua rau hluav taws xob zoo li qub:
Txhua yam tshuaj yog tsim los ntawm atoms, thiab cov qauv hauv nruab nrab ntawm atoms yog protons, neutrons, thiab electrons. Cov kws tshawb fawb txhais tau tias protons zoo, tsis muaj hluav taws xob, thiab cov electrons uas tsis zoo. Nyob rau hauv ib txwm ua, tus naj npawb ntawm protons ntawm tus atom yog tib yam li cov xov tooj ntawm electrons, thiab qhov zoo thiab tsis pom zoo, yog li sab nraud tshwm sim tsis muaj nqi. Txawm li cas los xij, vim muaj teeb meem sab nraud xws li kev sib txhuam los yog hauv daim ntawv muaj ntau yam xws li hluav taws xob, hluav taws xob, thermal energy, chemical zog, thiab lwm yam, qhov zoo thiab tsis muaj hluav taws xob hluav taws xob ntawm cov atom.
Qhov hluav taws xob tau zoo yog tsim los ntawm kev faib tawm cov nqi tsub los ntawm kev sib txhuam, thiab rov faib cov nqi vim tias muaj kev cuam tshuam cov nqi. Raws li ib txwm muaj, qhov zoo ntawm tus nucleus sib npaug rau qhov tsis zoo ntawm tus electron, qhov zoo thiab tsis zoo, yog li nws tsis paub. Txawm li cas los xij, yog tias cov electrons tawm ntawm orbit los ntawm sab nraud quab yuam, ua rau tsis siv koos pij tawj hluav taws xob, xws li qhov tseeb tias hluav taws xob tsis sib haum yog txheej txheem uas ua rau qhov tsis zoo thiab tsis zoo. Thaum ob qho khoom sib txawv sib txawv thiab rub tawm ib leeg, qhov electron ntawm ib qho khoom yuav raug xa mus rau lwm qhov, thiab lawv tau zoo vim tias tsis muaj electrons.
Thib ob, vim li cas tib neeg thiaj muaj hluav taws xob hauv lawv lub cev:
Thaum tib neeg lub cev txav, ntawm daim tawv nqaij rubbed tiv thaiv cov khaub ncaws thiab nruab nrab ntawm cov khaub ncaws thiab cov khaub ncaws, thiab hluav taws xob zoo li qub. Nrog rau cov khoom siv hauv vaj hauv tsev thiab hnav cov khaub ncaws ntawm cov tshuaj fiber ntau hauv lub caij ntuj no, qhov hluav taws xob hluav taws xob uas raug hluav taws xob tau los ntawm cov khoom siv hauv vaj hauv tsev yuav muab ntxig thiab tsim los ntawm tib neeg lub cev. Tsis tas li ntawd, sab hauv phab ntsa thiab cov plag tsev feem ntau yog cov thev naus laus zis, thiab cua yog qhuav, yog li lawv muaj feem raug hluav taws xob.
Cov khoom uas siv tshuaj los tiv thaiv zoo li qub
1. Kev hnav khaub ncaws zoo li qub thiab lub dab teg, pob tw
Cov khaub ncaws hnav zoo li qub tau muab faib rau cov khoom qub, cov khau loj, cov khau, cov hnab looj tes tiv thaiv los tiv thaiv, cov ntiv tes hno tiv thaiv zoo li qub, los tiv thaiv ntiv taw thiab zoo li ntawd. Nws tshem tawm cov hluav taws xob hauv hluav taws xob ntawm cov khaub ncaws los ntawm txoj kev tawm hauv lub cev thiab tawm ntawm cov khoom siv hluav taws xob. Txij li cov hlau tsis muaj fiber ntau rau cov hlau, cov tshuaj tua kab mob muaj cov kab mob ruaj khov hluav taws xob thiab tsis hloov vim lub sij hawm ntxhua khaub ncaws.
Lub pob zeb tiv thaiv no muaj nyob rau hauv txoj kev grounding, thiab nws tuaj yeem tso tus nqi ntawm tib neeg lub cev kom zoo, thiab yog ib qho tseem ceeb ntawm kev tiv thaiv khoom thaum tus neeg ua haujlwm cuam tshuam cov khoom hluav taws xob.
2. Los tiv thaiv pem teb
Anti-static av nplai tam sim no ua si lub luag hauj lwm tseem ceeb nyob rau hauv tus txheej txheem ntawm electrostatic tiv thaiv. Nws kuj muaj ntau hom kev ntsuas los tiv thaiv teeb meem, uas yog lub sij hawm-rhiab thiab ib ntus. Cov ntaub ntawv raug muab faib rau cov hlua hluav taws xob, PVC, conductive ceramics, thiab lwm yam. Txoj kev muab pov tseg yog muab faib rau hauv pem teb ncaj thiab pem hauv ntej, uas txiav txim tau raws li qhov tseeb cov nqi thiab cov nqi.
3. Anti-static lev
Cov txheej txheem los tiv thaiv lub rooj sib txig (static table mat) yog tsim los ntawm cov khoom qub thiab roj hmab. Nws feem ntau yog siv rau kev ua hauj lwm los tiv thaiv kev ua haujlwm ntawm cov kab sib dhos, khoom khib nyiab tiv thaiv, thiab ntau lawm hauv pem teb pas thiab pas ntoo. Cov xim ntawm txheej txheej ntawm cov khoom yog muab faib ua ntsuab nyom, cov khoom siv hluav taws xob yog ib qho chaw ua hauj lwm antistatic; hauv qab txheej yog dub, thiab cov khoom siv hluav taws xob yog xim dub.
