Ngexesha lokusebenza kwemihla ngemihla kwabaxubi bepowder, abaqhubi banokudibana nalo mbuzo udidayo:
Kutheni ezinye iipowder zixubana kakuhle nangokufanelekileyo, ngelixa ezinye zifuna ulawulo oluqinileyo lobushushu kunye nokufuma? Oku kudla ngokuvela kwingcamango eyintloko edideka lula—“umgubo owomileyo” xa kuthelekiswa “nomgubo wekhemikhali owomileyo.”Nangona zombini zibonakala ngathi ziipowder ezomileyo, ngokwembono yesayensi yezinto ezisetyenzisiweyo, zinezahluko ezisisiseko.
I. Iinkcazo
Igama elithi “umgubo owomileyo” ligama elibanzi elibhekisa kwizinto zokwenza imveliso zoshishino. Kwimiba yeshishini kunye netekhnoloji yomgubo, libhekisa kuzo zonke izinto ezikhoyo ngendlela yamasuntswana aqinileyo omileyo.
Ezi zinto zifumaneka kakhulu kwimveliso yemihla ngemihla yemizi-mveliso, njengomgubo womgubo kunye nobisi kwishishini lokutya, iipowders zamayeza, kunye neepigments kunye nezizalisi kwishishini leekhemikhali.
Ngokwembono yabaxubi bepowder, injongo ephambili ekucubunguleni le "powders eyomileyo" idla ngokufezekiswaukuxuba okufanayo ngokomzimbaIinjineli zokuxuba zigxila kakhulu kwizinto ezifana nokusasazwa kobungakanani bee-particle, i-particle morphology, uxinano, kunye nokuhamba kakuhle ukuqinisekisa ukuba izinto ezahlukeneyo azihlukani emva kokuxuba.
Ngokwahlukileyo koko, "umgubo wekhemikhali owomileyo" yingcamango ecacileyo nechazwe kancinci enomsebenzi ocacileyo weekhemikhali kunye nokusebenza kwayo.
Kwimiba yobunjineli kunye nokhuseleko lomlilo, eli gama libhekisa kudidi lweempuphu ezenziwe ngobunjineli ezidizayinwe ngeefomyula ezikhethekileyo zeekhemikhali. Azizo nje izinto ezibonakalayo, kodwa zikwayizinto ezisebenzayo ezineenjongo ezithile zeekhemikhali.
Eyona ndlela zisetyenziswa ngayo njengezinto zokucima umlilo. Umzekelo, umgubo wekhemikhali owomileyo we-ABC wenziwe kakhulu yi-ammonium phosphate, ngelixa umgubo wekhemikhali owomileyo we-BC wenziwe kakhulu yi-sodium bicarbonate. Ezi powder zenzelwe ukuba zenze ii-chemical reaction phantsi kweemeko ezithile (ezifana nokuvezwa emlilweni) ukuze kuthintelwe ukutsha.
II. Umahluko kwiMixer Processing
Kwimigubo eqhelekileyo eyomileyo, umsebenzi oyintloko womxube kukujonganaukuziphatha kokuxubana ngokomzimba.
Abaqhubi kufuneka balungise isantya sokuxuba kunye nobude bexesha ngokweempawu zezinto ezifana ne-engile yokuphumla kunye noxinano olukhulu, ukuze kuthintelwe ukuhluma emva kokuxubana. Injongo kukufezekisa "ukufana" ngokwasemzimbeni.
Yonke le nkqubo iguquguquka kancinci. Nangona ucoceko lokusingqongileyo, ubushushu, kunye nokufuma kusafuneka kuqwalaselwe, ngokubanzi akukho mngcipheko mkhulu weekhemikhali obandakanyekayo.
Nangona kunjalo, kwiipowders zekhemikhali ezomileyo, imingeni ekuxubeni iyatshintsha iyeuzinzo lweekhemikhali kunye nokuchaneka kokwenziwa.
Xa kucutshungulwa ezo powders, injongo ayisekho nje ukuxuba, kodwa ikwakukuba:
● ukuthintela iimpembelelo zekhemikhali ezingalindelekanga
● ukuqinisekisa umlinganiselo ochanekileyo wokwenziwa kwefomyula
● ukugcina uzinzo lokusebenza kakuhle
Umzekelo, kwimveliso yepowder yokucima umlilo, umlinganiselo we-ammonium phosphate kwizongezo kufuneka ube ngokuchanekileyo kakhulu. Nokuba ukuphambuka okuncinci kwindlela equlunqwe ngayo kunokunciphisa kakhulu ukusebenza kokucima umlilo okanye kubangele ukuba imveliso ingasebenzi kakuhle.
Ukongeza, ezi powders zihlala zi-hygroscopic kwaye zinokubonisa iimpawu ezithile zokubola okanye zokucaphukisa. Ke ngoko, iinkqubo zokuxuba zinokufuna ukuxhotyiswa ngezi zinto zilandelayo:
● iinkqubo zokuvala uthuli kunye nokuthintela ukuvuza ezisebenza kakuhle
● iinkqubo zokukhusela igesi ezingasebenziyo (xa kufuneka)
● iinkqubo zokulawula ubushushu ukunciphisa ubushushu obuveliswa kukungqubana ngexesha lokuxuba
La manyathelo anceda ekuthinteleni ukubola, ukonakala, okanye ukubola kwezixhobo ngexesha lokucubungula.
III. Iindawo zokusetyenziswa
Lo mahluko ubonakala ngakumbi kwizicelo zokucima umlilo.
Kwimigangatho yamazwe ngamazwe efana neenkqubo zokwahlulwa kwe-NFPA, igama elithi “umgubo owomileyo” lidla ngokusetyenziselwa ukubhekisa kwiiarhente zokucima umlilo ezikhethekileyo zeClass D metal fires, ngelixa elithi “umgubo wekhemikhali owomileyo” lidla ngokubhekisa kwiiarhente zokucima umlilo zeClass A, B, kunye neC.
Nangona kunjalo, kwiimeko zorhwebo nezemihla ngemihla, kuba ii-ABC dry chemical powders zezona zisetyenziswa kakhulu, la magama mabini adla ngokusetyenziswa ngokutshintshana.
Nangona kunjalo, nokuba kukho umahluko phakathi kwamagama, umgaqo osisiseko uhlala ungaguquguquki:
Umgubo wekhemikhali owomileyo sisixhobo esisebenzayo esenzelwe iinjongo ezithile zeekhemikhali, ngelixa umgubo owomileyo oqhelekileyo ngokuyintloko sisixhobo esikrwada esisetyenziselwa ukuxuba.
