Kudhinda kunoitwa pamusoro pechinhu, electrostatic phenomena inonyanya kuratidzwa pamusoro pechinhu. Iyo yekudhinda maitiro nekuda kwekukweshana pakati pezvinhu zvakasiyana, kukanganisa uye kubata, kuitira kuti zvinhu zvese zvinobatanidzwa mukudhindwa kwemagetsi akamira.
Kukuvadza kwemagetsi emagetsi
1. kukanganisa kunaka kwekudhindwa kwechigadzirwa
Iyo pamusoro peiyo substrate yakachajiswa, senge bepa, polyethylene, polypropylene, cellophane, nezvimwewo, inoshambadza guruva remapepa kana kuyerera mumhepo, guruva, tsvina, nezvimwewo, zvichikanganisa kufambiswa kweinki, kuitira kuti kudhinda kutumbuke, nezvimwe. ., zvichikonzera kudzikira kwemhando yezvigadzirwa zvakadhindwa. Chechipiri, zvakadai seinki ine mutero wemagetsi, mukufamba kwekubuda, kudhindwa kuchaonekwa pa "electrostatic inki spot", pamwero wekudhinda kwakaonda kunowanzoonekwa mumamiriro ezvinhu aya. Mundima yekudhinda, yakadai sekuchaja inki kubuda pamucheto wekudhindwa, zviri nyore kuoneka pamucheto we "inki whiskers".
2. Kukanganisa kuchengetedzwa kwekugadzirwa
Muchirongwa chekudhinda nekuda kwekumhanya-mhanya, kupfekenura kunoburitsa magetsi akamira, kana static magetsi anoungana kuti atungamirire nyore kumhepo inobuda, zvichikonzera kuvhunduka kwemagetsi kana moto. Kana iyo voltage yakakwira zvakanyanya, iyo inki inochajirwa ichakonzera iyo inki, moto wesolvent, kutyisidzira kwakananga kune kuchengetedzwa kweanoshanda.
Muedzo wemagetsi akamira
1. Chinangwa chikuru chekuyedzwa kwemagetsi static mukurongedza uye kudhinda zvidyarwa ndezvekuongorora dhigirii rekukuvadza; kudzidza matanho ekudzivirira; kutonga kushanda kwe static magetsi ekubvisa. Inofanirwa kudoma munhu ane mutoro we anti-static shangu, conductive shangu, anti-static hembe dzebasa uye imwe neimwe post yakajairwa static magetsi yekuona, mhedzisiro yacho ichaunganidzwa uye kuudzwa kune akakodzera madhipatimendi.
2. classification ye electrostatic monitoring project: kushandiswa kwezvinhu zvitsva kana chinhu chine static performance prediction; chaiyo yekugadzira nzira yekuchaja mamiriro ekuonekwa; electrostatic kuchengetedza matanho ekutonga kushanda kwekushandiswa kwekuonekwa.
(1) chinhu chine static magetsi kuita mapurojekiti ekufanotaura seanotevera: chinhu chepamusoro resistivity. Iko kushandiswa kwemamita akakwirira ekupikisa kana ultra-yakakwirira kupikisa mita kuyerwa, chiyero kusvika 1.0-10 ohms.
(2) iyo chaiyo kugadzirwa kwechaji yemuviri ine static magetsi ekuona mapurojekiti ndeaya anotevera: akachaja muviri electrostatic inogona kuyerwa, electrostatic inogona kuyera chiridzwa chine huwandu hwepamusoro hwe100KV hwakakodzera, iko kurongeka kwe5.0 level; tembiricha yenzvimbo yakapoteredza uye kuyerwa kwehunyoro hunyoro; chaja body running speed measurement; gasi rinopisa rinopisa kugadzirisa; conductive ground to ground resistance value kutsunga; Deray company's ACL-350 ndiyo yazvino vhoriyamu Iyo diki isiri-inobata digitaalinen electrostatic kuyerwa mita.
Static magetsi ekubvisa nzira mukudhinda
1. Nzira yekubvisa kemikari
Muchikamu chepasi chepamusoro chakavharidzirwa nemucheka we antistatic agent, kuitira kuti substrate conductive, ive zvishoma conductive insulator. Kemikari kubviswa kwechishandiso mukuita kune zvipingamupinyi zvakakura, sekuwedzera kwezvikamu zvemakemikari mubepa rekudhinda, iwo bepa mhando yeakaipa mhedzisiro, sekudzikisa simba rebepa, kunamatira, kusimba, kusimba kwesimba, nezvimwe. saka nzira yemakemikari haina kunyanya kushandiswa.
2. Nzira yekubvisa muviri
Usashandura hunhu hwezvinhu uchishandisa iyo electrostatic properties kubvisa, ndiyo inonyanya kushandiswa nzira.
(1) nzira yekubvisa pasi: kushandiswa kwesimbi conductor kubvisa static magetsi uye pasi kubatana, uye pasi isotropic, asi nenzira iyi hapana mhedzisiro pane insulator.
(2) humidity control kubvisa nzira
Kudhinda zvinhu pamusoro pekupokana nehunyoro hwemhepo kunowedzera uye kuderera, saka wedzera hunyoro hwemhepo, unogona kuvandudza conductivity yepepa. Dhinda shopu inokodzera mamiriro ezvakatipoteredza ndeiyi: tembiricha ingangoita 20 madhigirii, yakachajiswa nharaunda mwando we70% kana kupfuura.
(3) electrostatic kubvisa midziyo yekusarudza nheyo
Kudhinda chirimwa chinowanzo shandiswa electrostatic elimination equipment induction, high-voltage corona discharge type, ion flow electrostatic eliminator uye radioisotope mhando yakati wandei. Iwo maviri ekutanga akachipa, ari nyore kuisa uye kushandisa uye hapana atomic mwaranzi uye zvimwe zvakanakira zvinoshandiswa zvakanyanya :.
Induction type electrostatic eliminator bar: kureva, induction type electrostatic elimination bhurashi, musimboti ndewekuti muromo weeliminator padhuze nemuviri wakachajwa, induction ye polarity uye muviri wakachajiswa pane electrostatic polarity yemuchaji wakatarisana, nokudaro zvichiita kuti electrostatic neutralization. .
High-voltage discharge electrostatic eliminator: yakakamurwa kuva yemagetsi uye yakakwirira-voltage transformer mhando, maererano discharge polarity rakakamurwa unipolar uye bipolar, unipolar electrostatic eliminator chete ane pesvedzero pachaji, bipolar anogona kubvisa chero mhando muripo. Muchiito chekudhinda chinogona kushandiswa mukubvisa static magetsi bhurashi uye yakakwira voltage discharge mhando mbiri musanganiswa wenzira dzekubvisa static magetsi. Iyo musimboti weiyo static magetsi eliminator yekumisikidza nzvimbo: nyore kushanda, pakarepo mushure mechikamu chinotevera cheyekuputira solvent.
3. matanho ekudzivirira static magetsi
Iko kune electrostatic hazard process process equipment uye nzvimbo, inofanira kunge iri munzvimbo dzakapoteredzwa umo magasi anoputika anogona kuitika, simbisa matanho ekufemesa, kuitira kuti kusungirirwa kunodzorwa pasi penzvimbo inoputika; kudzivirira electrostatic insulators panguva yekuvhunduka kwemagetsi kune anoshanda, iyo insulator electrostatic inogona kutonga pazasi 10KV. Ikoko kune nzvimbo inoputika uye ine ngozi yemoto, vashandi vanofanira kupfeka anti-static shangu uye anti-static hovhorosi. Iyo nzvimbo yekuvhiya yakarongedzwa nevhu rinoita, conductive pasi kuramba pasi pasi pasi pe10 ohms, kuchengetedza iyo conductive zvivakwa, vanoshanda vanorambidzwa zvachose kupfeka synthetic fiber hembe (kunze kwehembe dzakagara dzichirapwa ne anti-static solution. ) munzvimbo iri pamusoro, uye zvinorambidzwa zvachose kubvisa hembe munzvimbo iri pamusoro.
