Ntau txoj hauv kev yog siv los xa cov nqi hluav taws xob rau cov khoom siv hluav taws xob tawg. Koj tuaj yeem siv cov roj av nchuav los ntawm tus nqi mus rau qhov chaw fuse, los yog cov hmoov phom tawg. Powder stopin kuj tseem siv, uas muab tso rau hauv cov ntawv ntim, lossis lwm txoj hauv kev muaj. Txawm li cas los xij, lawv tsis tuaj yeem ntseeg tau vim lawv tsis tuaj yeem muab lub sijhawm kub hnyiab ntawm qhov deb, thiab lawv tsis tuaj yeem siv rau huab cua phem lossis thaj chaw tshwj xeeb.
Ib zaug, txoj hlua pickford tau nrov heev, uas tuaj yeem tiv nrog yuav luag txhua txoj haujlwm ntawm lub sijhawm ntawd. Nws tau ua ua ntej, uas ua rau nws muaj peev xwm nqa tawm blasting yam tsis muaj ncua sij hawm. Nws tuaj yeem hlawv txawm tias lub teeb los nag thiab cua, thiab kuj tau muab lub tswv yim meej ntawm lub sij hawm detonation, txij li cov khoom tseem ceeb hauv nws yog hmoov stopin, uas muaj qee lub sij hawm kub hnyiab (ib thib ob ib meter ntawm qaum).
Lwm qhov tshwj xeeb uas fickford qaum muaj yog nws elasticity. Nws tuaj yeem dov dawb, nqa tau yooj yim, thiab thaum npaj qhov tawg, qhwv nws tom qab txhua qhov kev cuam tshuam, uas tso cai rau sappers los teeb tsa cov nqi luv luv, thaum lawv lawv tus kheej tuaj yeem nyob hauv npog.
Zoocov khoom ntawm fickfords, qaum, qhov chaw tsim khoom uas muaj nyob rau hauv winding nres nrog textiles, tau txais vim qhov tsim. Qhov tseeb yog tias cov khoom nquag tau qhwv nrog ib txheej ntawm cov ntaub, uas yog impregnated nrog rab phom. Qhov no ua kom muaj kev sib xyaw ua ke thiab tiv thaiv kom tsis txhob muaj kev sib tsoo. Tom ntej no, ib txheej thib ob ntawm textile yog siv, uas yog smeared nrog bitumen. Nws tiv thaiv nws los ntawm ya raws, muab elasticity ntxiv thiab muab cov pa oxygen rau lub fickford qaum thaum combustion, uas yog ib qho tseem ceeb heev.
Txawm li cas los xij, txoj hlua hluav taws kub dej no muaj qhov tsis zoo. Nws tsis zam qhov kub tsis zoo, vim nws tawg thiab tawg. Nws kuj tuaj yeem ua kom ntub dej, thiab nyob rau hauv tej yam kev mob ntawm high humidity los yog nyob rau hauv dej nws yog xyaum tsis siv. Tias yog vim li cas hnub no nws yog suav hais tias yog tsis siv lawm, thiab thaum nqa tawm blasting fickfords, lub qaum yog xyaum tsis siv nyob qhov twg.
Muaj ntau lwm cov lus qhia hluav taws kub uas muaj kev ua tau zoo dua thiab kev ntseeg siab. Nyob rau tib lub sijhawm, lawv cov khoom tsim tau yooj yim dua thiab pheej yig dua, uas tuaj yeem txo tus nqi ntawm blasting. Bickford qaum yuav luag tsis tuaj yeem yuav hnub no. Txawm hais tias cov khw muag khoom feem ntau muag lwm cov ntawv qhia hluav taws uas siv cov thev naus laus zis sib txawv thiab siv cov ntsiab lus sib txawv, tab sis uas muaj tib lub npe. Peb tuaj yeem hais tias tsuas yog lub npe tseem tshuav ntawm thawj qhov kev tsim tawm ntawm ntau pua xyoo dhau los, uas tau ruaj khov rau hauv tib neeg lub cim xeeb.
Yog li, fickford qaum tuaj yeem yuav ntawm txhua lub khw tshwj xeeb lossis nqa los ntawm cov khoom siv hluav taws xob niaj hnub. Qhov twgcov ntawv luam tawm yuav zoo ib yam li cov thawj xyoo dhau los tsuas yog pom tau. Qhov tseeb, qhov no yog ib qho khoom sib txawv kiag li uas ua tau raws li cov kev xav tau niaj hnub no thiab kev ua haujlwm.
