Umdleke Wokubeka Kwemibhali (30° + Umkhakha Wokuvuselela) Ukunciphisa Ukuphatha Kwe-Tribo Nokuphatha Kokugcina

Isibezo sokubeka kwe-30° esihle kangaka sisebenzisa ukungafani kwezindlela zokugcina amandla okusakaza ngokuthintana kwesibezo nesithakazelo—lokhu kuyisidingo esibalulekile kuqondisa izinto ezincane, apho ukungafani kwezindlela zokugcina amandla kwenza amandla angavumelekile. Ngokudibaniswa nezindlela zokuhlela (okuvamile ukuba kubili-0.5–1.5 mm), lokhu kususa izinyathelo ezingaphambili ezinokuthintana ngamandla okusakaza nokuphuma kwamandla, futhi kunciphisa isibezo sokusakaza ngaphezu kwe-60% (I-Journal Yokuxhumana Nokuphatha Amadusti 2022). Isibezo sokuhlela esingaphansi kususela kumakhanda akhona ukuthi kufike kwezindawo eziningi kwezindawo zokuphuma kwamandla okusakaza, okuyisidingo esibalulekile sokuphulwa kwezindawo zokuphuma kwamandla okusakaza. Ukukhetha i-durometer (okuvamile ukuba kubili-80A–90A Shore) kubalansisa ukuthintana nokunqoba nokunqoba okufanele ukuthintana ngokuphelele nesithakazelo ngaphandle kokuthintana kakhulu. Izinhlelo zokubeka ezinokuthintana ngokuphambuka kwezindawo zokuphuma kwamandla ziyagcina isibezo sokuxhumana nokuphatha, zisusela kwezindawo zokuphuma kwamandla okusakaza nokuthintana kwezindawo zokuphuma kwamandla.

Lokhu kuchazwa kwezindlela zokusebenza kuzokuvikela ukuthi kufanele kube yini ngokwesibonelo se-ATEX futhi kuzokubusa izikhathi zokusisha—kukhombisa izinkinga zezimali nezimali kwezindawo zokuphatha izinkampani ezinamandla.

Ukuhlanzwa nokuhlaziywa: Ngaphezu kwezimali zokugcina isibonelo esingaphansi kwezindawo zase-ATEX/IECEx Zone 21 nase-MSHA

Kungani Ukuthi Ukubala Kwemali Yomkhakha + Ukubala Kwesilinganiso Sokugcina Isithunzi (IEC 61340-4-1) Kuyisisekelo

Ukubeka ubuhle bakho kuphela ematholeni okugcina isibonelo esingaphansi kwezimali zokugcina isibonelo esingaphansi kweziblade zokususa amasiko esibonelo se-ATEX kuyenza izikhululeko ezingavumelekileyo kwezimali zokuhlanzwa. Kwezindawo zokugcina amakhanda okwesilika noma amagraini, umthelela wokugcina isibonelo esingaphansi kungabiza izimali zokugcina isibonelo esingaphansi, kubuka izinkinga zokugcina isibonelo esingaphansi ezinamandla okugcina isibonelo esingaphansi ezinamandla okugcina isibonelo esingaphansi. Ukubala kwemali yomkhakha kubala ukuthi amandla ayagcina isibonelo esingaphansi kwenqubo yomkhakha wonke, kubuka izinkinga ezingafihliwe.

Isiqhelo se-IEC 61340-4-1 sibiza ukuzilungiselela kwe-resistivity yomkhawulo ne-tribocharging rate ngokuhlanganisa. Lokhu kusimula izimo zokufana kwemithambo nezinto eziphathelene nempilo, kubala amasparki okuphazimula phakathi kokusebenza kwezinkinga. Uma akukho lokuzilungiselela kwezimbili, imithambo ingalungiselelwa kwezinye izikhathi kodwa ingabangela amasparki angaphezulu kwe-3,000 mJ ngokugcina kwezindawo ezinkulu—kuyaphikisana nokuthi isikhundla sokuphazimula kwezincwadi zemithambo siyisikhundla sokuphazimula esingaphezulu kwe-0.25 mJ.

Kusukela ku-Zone 21/22 (izindawo zokuphazimula kwezincwadi), i-ATEX ne-IECEx zibiza izirhwebu zokuzilungiselela kwe-IEC 61340-4-1 ezilungile, ngokuhlanganisa nezirhwebu zokulungiselela kwe-MSHA zokulinda ukugcina. Lokhu kuvumela ukuthi imithambo ibe yezinkulungwane zokulungiselela ukuphazimula ngokuphelele kwezindlela zokusebenza—akukho kuphela ngokufakwa.

Imibuzo Evame Ukubuzwa

Kungani imithambo yezinkulungwane zokulungiselela ukuphazimula kubalulekile kuzindawo zokuphazimula kwezincwadi?
Bazivimba ukuphazimula okwenzeka ngamasparki wokuphazimula ngokuthi bakhupha umoya ngendlela evumile, okubalulekile kuzindawo apho izincwadi ziyathatha isikhundla sokuphazimula.

Yini lezindlela zokusebenzisa izinkulungwane zokulungiselela ukuphazimula njenge-carbon black kule mithambo?
Izinkokhelo zokugcina ezinamandla njengecarbon black, i-CNTs, ne-graphene zifakwa ukuze kufikwe imiphumela yokungagcina isithakazelo ngaphandle kokukhula kwezinkinga zemithombo yezinye izinto zokusebenza.

Izicertifiketi eziyini okufanele zibe nazo lezi ziblade?
Kufuneka zibe nesicertifiketi se-ATEX/IECEx/MSHA, esibonisa ukuthi ziyasebenza ngokuphelele futhi zisafule kumilayimu eyodwa yezindawo eziphakeme kakhulu.
