Ziva nezve anti-static esd mapurasitiki

Zvigadzirwa zvepurasitiki zvinoshandiswa zvakanyanya munzvimbo dzakasiyana siyana senge midziyo yemumba, kutakura, magetsi uye magetsi nekuda kwezvivakwa zvavo zvakanakisa. Nekudaro, izvi zvakakwirira zvekusimbisa zvivakwa uye zvinowanzoita muchishandiso, nekuda kwekunyepedzera kupfava uye kugadzira, kuunganidzwa kwemhosva yemagetsi, kugadzirwa kwetsivi dzakawanda dzakavanzika.

Izvo zvinhu zvinogona kukanganisika zvinoenderana nekwavo kupokana:

Inosimbisa Zvishandiso: 10 ^ 12 ~ 10 ^ 15 OHM / SQ

Zvinyorwa zveAntisticatic: 10 ^ 10 ~ 10 ^ 12 OHM / SQ

Static dissipative zvinhu: 10 ^ 6 ~ 10 ^ 12 ohm / sq

Zvigadzirwa Zvekuitisa: ≤ 10 ... 5 OHM / SQ

Maitiro ekubvisa magetsi akaunganidzwa pane pamusoro pezvigadzirwa zvepurasitiki pamwe nekudzivirira kuti gadzirise magetsi emagetsi ave ari munda wakakurumbira mumunda wePolymer

Iyo huwandu hwemagetsi emagetsi inogadzirwa nema plastics inogona kutaurwa maererano nekwavo pasi pepfungwa kana vhoriyamu kuramba. Mhando dzakasiyana dzezvigadzirwa zvepurasitiki dzinowanzoratidza zvakasiyana pasi pepasi pepamusoro uye vhoriyamu kuramba. Kazhinji, iyo yakakura kupokana kana kuvhiringidza kupokana, zviri nyore kune zvigadzirwa zvepurasitiki kuti zviunganidze magetsi, uye zvakanyanya kukosha kweiyo yemagetsi yeagetsi.

Kurongeka kwekuraira ndekwekuti:

(Zvakakodzera Kubhadharwa) Polyurethane, nylon, acetate, polypropylene, polyvinylone chloride, polyethylone copolymer, polythylene, polytetrafluorolene (polytetrafluorolene (polytetrafluorolene (polytetrafluorolene (polytetrafluorolene)

Electrostatic njodzi

(1) Electrocution

Muzhinji, magetsi emagetsi haikonzere kukuvadza kumunhu, asi electrocution inogona kuitika, nekuti zvishoma zvidiki zvidhori, zvakaringana kugadzira iyo yakanyanya sticic voltage.

Semuenzaniso, mukugadzirwa kwemufananidzo wemufananidzo, iyo manhamba voltage yakagadzirwa dzimwe nguva inogona kuve yakakwira zviuru zvemavara, zvichiita kuti zvive nyore kuti vanhu vave malek. Kazhinji kuburitsa electrocution static voltage ye 8000V.

(2) discharge

Kana iyo Static Voltage yakakura kupfuura 500V, kusimuka kwechiitiko kunogona kuitika, kana paine zvinhu zvinopisa munharaunda panguva ino, zvinowanzotungamira kumoto mukuru uye nekuputika kwangu uye nemoto, zvinokonzerwa nezvinhu zvepurasitiki inogadzirwa nemagetsi magetsi.

.

Semuenzaniso, mukugadzira maitiro epurasitiki yefirimu, nekuda kwekukwezva kwemagetsi, kugadzira iyo firimu inonamatira kumishini, isiri nyore kutoreredzwa. Mumwe muenzaniso, nekuda kwekukwezva electrattraction, zvigadzirwa zvepurasitiki zvichashambadzira guruva mumhepo, zvichikanganisa runako rwezvigadzirwa; Firimu kugadzira maitiro nekuda kweiyo static yemagetsi uye inokanganisa kujekesa kweiyo firimu uye nemhando yepamusoro yekodhi uye zvichingodaro.

Antisticatic application

Static kubvumidzwa kunoda kuvhiringidza kuvhiringidzika kweshoma pane 10 ^ 12 ω ω ^ 12 ω get-cm

Electromagnetic Shancoves inodiwa vhoriyamu kupokana mu 10 ~ 10 ^ - cm. Electromagnetic wave kukanganiswa ndiko kwakanangana neruzha, kuyerwa mune madhiri (DB). Kuchengetedzeka kuyamadza kwakanaka kana kwakaipa, kunogona kukamurwa mumakwenzi anotevera: Yakadzika shoeling 10 ~ 30db; Shoelinging 30 ~ 60db; yakanaka yekuchengetedza 60 ~ 90DB; High Shielding> 90DB. Semuenzaniso, zvishandiso zvemagetsi zvinoda kuvharidzira kusvika ku 35DB kana anopfuura.

Muitisi wemagetsi anoda vhoriyamu kupokana pazasi 10 ω-cm.

Zvigadzirwa zveAntisticatic

Kunyangwe chigadzirwa chepurasitiki chichatakura zvigadzirwa zvemagetsi kana hukuru hwemagetsi emagetsi zvinogona kuongororwa nehoriyamu kupokana kana magetsi maitiro.

Insulator: Vhoriyamu Rudzidziso> 10 ^ 12 ω-cm kana Ditrive <10 ^ -9s / cm.

Semiconductor: Vhoriyamu Rudzidziso 10 ... 6 kusvika 10 ^ 12 ω-cm kana Docitivity 2 kusvika 10 ^ -9s / cm.

ConcerT: Vhoriyamu Rudzidziso <10 ^ 6 ^ 6 ω-cm, kana Docitivity> 2S / cm.

Akanaka Conductor: Vhoriyamu Rudzidziso <10ω-cm

Maantistatic plastics anoda vhoriyumu yavo kuramba pasi pegumi ... 12 ω-cm;

Mafambiro ekugadzirisa anoda vhoriyamu yavo yekupesana kuti isingasviki 10 ^ 6 ω get-cm kana kuitisa> 2S / cm.

Anti-static mapurasitiki anowanzo kukamurwa mumhando dzinotevera:

1. Actorsing Purastics: Aya mapurasitiki anowanzo kuvhenganiswa nevanoita vamiririri, senge kabhoni dema kana simbi poda, panguva yekugadzira yekugadzira kuti uwedzere kuitwa kwepurasitiki. Aya mapurasitiki anowanzove aine magetsi epamusoro maitiro, ayo anogona kunyatso bvisa kana kuderedza kuvaka kweiyo static magetsi. Comments maitiro ekugadzirisa anosanganisira polypropylene, polyethylene, uye polystyrene

2. Antistatic Plastics: Aya mapurasitiki anowanzo kuve pamusoro pekurapa kwakakosha, kuitira kuti iwane huwandu hwehukama, nekudaro kuderedza chizvarwa kana kuunganidzwa kwemagetsi. Uku kurapwa kunosanganisira nzvimbo yekufambisa, wedzera antistatic mumiririri. MaPurasitiki epurasitiki anowanzo shandiswa mukuda kudzivirira kupindira kwemagetsi asi haadi huwandu hwekuita chiitiko chechiitiko, chakadai seyemagetsi zvigadzirwa, zvigadzirwa zvekurapa uye zvichingodaro.

3. Electrostatic Plastic Purasitiki Static Shoeling Plassics inowanzo shandiswa muzvigadzirwa zvemagetsi senge shells, electromagnetic yekuvhara uye zvimwe zvikamu.

4. Static dissipative plastics: idzi mapurasitiki vane kukurumidza kuburitsa magetsi emagetsi kunzvimbo yakatenderedza, nekudaro inoderedza kuunganidzwa kwemagetsi emagetsi. Static dissiparative plastics inowanzo kuve pamusoro mushure mekurapa kwakakosha kana kuwedzerwa kuti ugone kuburitsa kurapa kwekupomerwa kweiyo compand, yakadai sehodhi. Ivo vanowanzoshandiswa mune zvekushandisa izvo zvinoda kukurumidza kuburitswa kwemagetsi emagetsi, akadai seSemiconductor kugadzira zvigadzirwa uye guruva kuputika nzvimbo dzine njodzi.
