Ukuprintwa kuqhutyelwa kumphezulu wento, i-electrostatic phenomena nazo zibonakaliswa ngokukodwa kumphezulu wento. Inkqubo yoshicilelo ngenxa yengxabano phakathi kwezinto ezahlukeneyo, impembelelo kunye noqhagamshelwano, ukuze zonke izinto ezibandakanyekayo kushicilelo lombane omileyo.
Umonakalo wombane omileyo
1. kuchaphazela umgangatho woshicilelo lwemveliso
Umphezulu we-substrate ehlawuliswayo, njengephepha, i-polyethylene, i-polypropylene, i-cellophane, njl., iya kubhengeza uthuli lwephepha okanye ukudada emoyeni, uthuli, ukungcola, njl., okuchaphazela ukuhanjiswa kwe-inki, ukwenzela ukuba ushicilelo luqhakaze, njl., okubangelwa ukuhla komgangatho weemveliso eziprintiweyo. Okwesibini, njenge-inki enomrhumo wombane, ekuhambeni kokukhutshwa, ukuprintwa kuya kubonakala "kwindawo ye-inki ye-electrostatic", kwinqanaba lokushicilela elincinci lihlala livela kule meko. Kwintsimi yokushicilela, njengokukhutshwa kwe-inki ehlawulisiweyo kwi-edge of the print, kulula ukuvela kumda "we-ink whiskers".
2. Ukuchaphazela ukhuseleko lwemveliso
Kwinkqubo yokushicilela ngenxa yesantya esiphezulu, ukuhluthwa kuya kuvelisa umbane ongatshintshiyo, xa umbane we-static uqokelela ukukhokelela ngokulula ekuphumeni komoya, okubangela ukutshitshiswa kombane okanye umlilo. Xa i-voltage iphezulu kakhulu, i-inki ehlawulisiweyo iya kubangela inki, i-solvent fire, isongelo ngqo kukhuseleko lomsebenzisi.
Uvavanyo lombane omileyo
1. Injongo ephambili yovavanyo lombane ongatshintshiyo ekupakishweni nasekushicileleni izityalo kukuhlalutya ubungakanani bomonakalo; amanyathelo okuthintela ukufunda; gweba ukuphumelela kokupheliswa kombane ongatshintshiyo. Kufuneka ukhethe umntu ojongene nezihlangu ezichasene ne-static, izihlangu zokuqhuba, iimpahla zokusebenza ezichasene ne-static kunye nesithuba ngasinye sokubonwa kombane osisigxina, iziphumo ziya kuhlanganiswa kwaye zixelwe kumasebe afanelekileyo.
2. Ukuhlelwa kweprojekthi yokufumanisa i-electrostatic: ukusetyenziswa kwezinto ezintsha ekrwada xa into enoqikelelo lwentsebenzo engatshintshiyo; eyona nkqubo yemveliso ihlawuliswa ukubhaqwa kwemeko; amanyathelo okhuseleko lwe-electrostatic ukugweba ukusebenza kokusetyenziswa kokubona.
(1) into eneprojekthi yokuqikelela ukusebenza kombane ongatshintshiyo zezi zilandelayo: ukumelana nomphezulu wento. Ukusetyenziswa kwemitha yokumelana nomgangatho ophezulu okanye i-ultra-high resistance resistance measurement, uluhlu oluya kwi-1.0-10 ohms.
(2) eyona mveliso yequmrhu elihlawuliswayo kunye neeprojekthi zokubona umbane ongashukumiyo zimi ngolu hlobo lulandelayo: umzimba ohlawuliweyo umlinganiselo we-electrostatic enokubakho, isixhobo sokulinganisa esinokubakho sombane esinoluhlu oluphezulu lwe-100KV lufanelekile, ukuchaneka kwenqanaba le-5.0; ubushushu bendawo engqongileyo kunye nomlinganiselo wokufuma onxulumeneyo; umlinganiselo wesantya esibalekayo somzimba ohlawuliweyo; ukuzimisela koxinzelelo lwegesi evuthayo; umgangatho wokuqhuba ukumisela ixabiso lokumelana nomhlaba; I-ACL-350 yenkampani ye-Deray ngumthamo wangoku Owona mitha womlinganiselo omncinci ongaqhagamshelwanga wedijithali.
Iindlela zokuphelisa umbane omileyo ekushicileleni
1. Indlela yokuphelisa iikhemikhali
Kwi-substrate surface efakwe umaleko we-agent ye-antistatic, ukuze i-substrate conductive, ibe yi-insulator eqhuba kancinci. Ukupheliswa kweekhemikhali kwesicelo ekusebenzeni kukho imida emikhulu, njengokongezwa kwamacandelo ekhemikhali kwiphepha lokushicilela, umgangatho wephepha leempembelelo ezimbi, ezifana nokunciphisa amandla ephepha, ukunamathela, ukuqina, amandla okuqina, njl., ngoko ke indlela yeekhemikhali isetyenziswa kakhulu.
2. Indlela yokuphelisa ngokwasemzimbeni
Musa ukutshintsha ubume bezinto usebenzisa iimpawu ze-electrostatic ukuphelisa, yindlela esetyenziswa kakhulu.
(1) indlela yokuphelisa umhlaba: ukusetyenziswa kwee-conductors zetsimbi ukuphelisa umbane ongatshintshiyo kunye noqhagamshelwano lomhlaba, kunye nomhlaba we-isotropic, kodwa ngale ndlela akukho mpembelelo kwi-insulator.
(2) indlela yokuphelisa ulawulo lokufuma
Ukuchaswa komphezulu wezinto zokushicilela kunye nokufuma komoya kwanda kwaye kuyancipha, ngoko ke ukwandisa ukufuma komoya ohambelanayo, unokuphucula umgangatho wephepha. Ivenkile yokuprinta ilungele iimeko zokusingqongileyo zezi: ubushushu obumalunga nama-20 degrees, ukufuma kwemo engqongileyo yomzimba ohlawulisiweyo ngama-70% nangaphezulu.
(3) imigaqo yokukhetha izixhobo zokuphelisa i-electrostatic
Iplanti yoshicilelo esetyenziswa ngokuqhelekileyo izixhobo zokuphelisa i-electrostatic, uhlobo lokukhutshwa kwe-corona ephezulu yombane, i-ion flow electrostatic eliminator kunye nohlobo lwe-radioisotope eziliqela. Eyokuqala ezimbini zazo zitshiphu, kulula ukuyifaka kunye nokusetyenziswa kwaye akukho mitha yeathom kunye nezinye iingenelo zisetyenziswa ngokubanzi:.
Uhlobo lokungeniswa kwe-electrostatic eliminator bar: oko kukuthi, uhlobo lokungeniswa kwebrashi yokuphelisa i-electrostatic, umgaqo kukuba incam ye-eliminator kufutshane nomzimba ohlawuliweyo, ukufakwa kwe-polarity kunye nomzimba ohlawulisiweyo kwi-polarity ye-electrostatic yentlawulo echaseneyo, ngaloo ndlela yenza i-electrostatic neutralization.
I-high-voltage discharge electrostatic eliminator: yahlulwe ibe yi-electronic and high-voltage transformer type, ngokutsho kwe-polarity yokukhupha yahlulwe ibe yi-unipolar kunye ne-bipolar, i-unipolar eliminator ye-electrostatic inefuthe kuphela kwintlawulo, i-bipolar inokuphelisa naluphi na uhlobo lwentlawulo. Kwinkqubo yoshicilelo ingasetyenziselwa ukupheliswa kwebhrashi yombane omileyo kunye nohlobo lokukhutshwa kwamandla ombane aphezulu udityaniso lweendlela ezimbini zokuphelisa umbane ongatshintshiyo. Umgaqo wokufakela indawo yokufakelwa kombane we-static eliminator: kulula ukusebenza, ngokukhawuleza emva kwenxalenye elandelayo ye-solvent yokugubungela.
3. amanyathelo okuthintela umbane ongatshintshiyo
Apho kukho izixhobo zenkqubo yeengozi ze-electrostatic kunye neendawo, kufuneka zibe kwindawo ezingqongileyo apho iirhasi eziqhumayo zinokuthi zenzeke, zomeleze amanyathelo okungenisa umoya, ukuze ugxininiso lulawulwe ngaphantsi koluhlu lokudubula; ukuthintela izithinteli ze-electrostatic ngexesha lokutshatyalaliswa kombane kumqhubi, i-insulator electrostatic enokubakho ulawulo olungaphantsi kwe-10KV. Apho kukho ugqabhuko-dubulo kunye nommandla wengozi yomlilo, abaqhubi kufuneka banxibe izihlangu ezichasene ne-static kunye nee-ovaroli ezichasayo. Indawo yokusebenza igalelwe umhlaba ophetheyo, ukuchasana komhlaba okuqhubayo emhlabeni kungaphantsi kwe-10 ohms, ukugcina iipropati zokuqhuba, abaqhubi bathintelwe ngokungqongqo ukuba banxibe iimpahla zefiber zokwenziwa (ngaphandle kweempahla eziye zaphathwa rhoqo ngesisombululo esichasene ne-static) kule ndawo ingasentla, kwaye kuthintelwe ngokungqongqo ukukhulula kule ndawo ingasentla.
