Njengoba umkhiqizo, embonini yokudla neminye imikhiqizo yezimboni, ngesimo sokusebenza kuyahlukahluka, impahla ye-powder nayo ivame kakhulu.
Lokhu kwenza uhlelo lokusebenza emaphaketheni, nakanjani kuyoba phama powder uhlobo lwezimpahla, ngakho, yini imbangela imishini ukupakisha powder kuqhuma?
Isimiso sokuqhuma kwempushana: okokuqala ukubheka ukuhlukaniswa kothuli oluqhumayo nokuhlanganisana.
Ngokuvamile kulula ukuqhuma ingozi ye-aluminium powder, i-zinc powder, i-ferrosilicon powder, i-magnesium powder, i-iron powder, i-aluminium processing grinding powder, zonke izinhlobo ze-plastic powder, ukuhlanganiswa kwe-organic of intermediates ezenza imithi, ufulawa kakolweni, ushukela, amapulangwe ezinkuni, udayi. , i-bakelite ash powder, i-milk powder, itiye, uthuli lwempushana kagwayi, uthuli lwamalahle, ne-plant fiber njll.
Lezi zinto ziyimbangela yokuqhuma kothuli oluvutha kalula lunezakhi ezinamandla zokunciphisa u-H, C, N kanye no-S ezifana nokuba khona, lapho zihlala ndawonye ne-peroxide nothuli oluqhumayo, bese zibola, ngokusabela kwe-oxidation ukukhiqiza inani elikhulu legesi, noma igesi. inani lincane, kodwa khulula inani elikhulu lokushisa kokuvutha.
I-aluminium powder, isibonelo, inqobo nje uma umkhathi we-carbon dioxide usengozini yokuqhuma.
ukuqhuma kothuli kalula kuya kokubonakalayo, izakhiwo zamakhemikhali zothuli nezimo zemvelo.
Ngokuvamile cabanga ukuthi izinto ezisetshenziswayo maningi amathuba okuba zibe khona ekushiseni kokuqhuma, njengothuli lwamalahle, ikhabhoni, isulfure, njll.
Isivinini se-oxidation sezinto eziqhuma kalula, njenge-magnesium powder, i-aluminium powder, i-ferrous oxide, udayi, njll.
Uthuli olushajiwe kulula futhi ukubangela ukuqhuma, njenge-synthetic resin powder, uthuli lwefiber, isitashi, njll.
Lezi zinto ezimbi ezisetshenziswayo ezinomshini noma i-air friction electrostatic eqoqiwe, lapho ifinyelela inani elithile, ingakhipha ukukhishwa kwenhlansi kagesi, ukuqhuma komlilo.
ngokuvamile akulula ukubangela ukuqhuma kothuli inhlabathi, isihlabathi, i-iron oxide, izinto zokugaya, usimende, uthuli lwe-quartz nothuli ngemva kokufana nokuvutha.
Amakhemikhali anjalo omzimba othuli azinzile, ngakho akulula ukuwashisa.
Kodwa uma lolu hlobo lothuli lukhiqizwa kwinkungu kawoyela ne-CO, CH4 kanye negesi negesi evuthayo, nakho kulula ukuqhuma.
ukuqhuma kothuli okubukwayo okwakhiwa yintuthuko emithathu elandelayo: enye iwuthuli oluntantayo ngaphansi kwesenzo sokushisa ukukhishwa kwe-distillation ngokushesha okomile noma ukufakwa kwegesi ukukhiqiza igesi evuthayo;
Okwesibili, ingxube yegesi evuthayo nomoya kanye nokuvutha;
Okwesithathu kuwuthuli olukhishwa ukushisa okushisayo, ukudluliswa kokushisa kanye nendlela yokumiswa noma eduze kothuli, ngemva kokuqhubeka komjikelezo wokushisisa oshisisa uthuli.
Ngokulandelana kweluphu ngayinye, izinga lokusabela liye lasheshiswa, ngokushisa okukhulu, ukuqhuma kokwakheka kokuphela.
Lokhu kusabela kokuqhuma kwelangabi nesivinini sokuqhuma, isivinini samagagasi okuqhuma, ingcindezi izoqhubeka nokusheshisa futhi ikhule, kanye nentuthuko ngokugxuma nemingcele.
ukuhlaziywa okungenhla kwezimbangela ze-vacuum
umshini wokupakisha ngoba i-powder packaging explosive, futhi leli phepha lethula isimiso sokuqhuma kothuli futhi kulula ngathi ukukhiqiza i-powder explosive substance, kholelwa ukuthi ingasisiza kangcono ukugwema izingozi ezinjalo.
Ngakho-ke, lapho sikhetha
umshini wokupakisha, uzonaka kumele akhethe imikhiqizo engaqhumi, lokhu kubaluleke kakhulu.
