Nyob rau hauv xyoo tas los no, raws li ib yam tshiab ntawm fastening khoom,integrated rau testau txais kev lees paub kev lag luam sai thiab cov neeg siv khoom txaus siab vim lawv txoj haujlwm-txuag, yooj yim, ua haujlwm tau zoo thiab nyab xeeb, thiab tau qhia txog kev txhim kho sai. Piv nrog rau cov tsoos expansion bolt fastening txoj kev, nws muaj ob qho zoo heev.
Ua ntej tshaj plaws, cov ntsia hlau sib xyaw muaj nws tus kheej lub zog thiab tsis tas yuav txuas nrog hluav taws xob lossis roj. Nws yog lub teeb thiab portable thiab tuaj yeem ua tiav cov haujlwm fastening nrog tsuas yognuv gunthiab integrated fastener.
Qhov thib ob, tsis tas yuav tsum muaj qhov siab-altitude drilling, kev tsim kho yooj yim thiab ceev, kev siv zog tsawg, kev tsim kho tau zoo dua qub (ntau dua 20 zaug), thiab cov nqi tsim kho tau txo qis heev.
Tam sim no, cov ntsia hlau sib xyaw ua ke ntawm kev ua lag luam tuaj yeem muab faib ua peb pawg raws li lawv cov khoom: binary explosive integrated rau tes, nitrocellulose integrated rau tes, thiab“ntau lub hauv paus tawg”integrated rau tes. Yog li, dab tsi yog qhov txawv ntawm peb hom kev sib xyaw ua ke ntawm cov ntsia hlau, thiab peb yuav xaiv li cas?
Kev sib xyaw
1.1ob lub hauv paus explosives yog tsim los ntawm nitrocellulose (NC, tseem hu ua nitrocellulose) thiab nitroglycerin (NG), feem ntau nyob rau hauv daim ntawv granular. Granularob lub hauv paus explosives yuav tsum tau ua los ntawm nitrocellulose uas ua tau raws li cov kev cai ntawm GJB 3204A-2020 thiab nitroglycerine uas ua tau raws li cov kev cai ntawm GJB 2012-1994 raws li cov ntaub ntawv tseem ceeb, thiab yuav tsum tsis txhob muaj detonators, hlau hmoov, combustion catalysts, khoom tawg thiab txwv oxidants. Nws yog txiav txim los ntawm lub xeev. Nws muaj cov yam ntxwv ntawm lub zog siab, qis hygroscopicity, zoo lub cev ruaj khov, thiab ruaj khov ballistic kev ua tau zoo.
1.2 Nitrocellulose (tseem hu ua single-base explosive) yog tsim los ntawm nitrocellulose thiab feem ntau yog cylindrical. Cylindrical ib puag ncig tawg yuav tsum tau ua los ntawm nitrocellulose uas ua tau raws li cov kev cai ntawm GJB 3204A-2020 raws li cov khoom siv tseem ceeb, nrog cov ntsiab lus nitrogen tsis pub tsawg dua 12.60%. Lawv yuav tsum tsis txhob muaj cov detonators, hlau hmoov, combustion catalysts, khoom tawg los yog oxidants thiab lub zog tivthaiv txwv los ntawm lub xeev. Yooj yim heev.
1.3 Nws“multi-base explosives”tiag tiag ntxiv lub zog txhawb zog, muaj zog oxidants, thiab npib tsib xee hydrazine nitrate (ib qho oxidant txwv tsis pub los ntawm lub xeev) thiab lwm yam tshuaj rau cov hmoov ib leeg los txhim kho lawv cov khoom ua tau zoo thiab ua tiav cov txiaj ntsig ntawmob lub hauv paus explosives. . Qhov laj thawj tseem ceeb yog tias cov ntsiab lus nitrogen ntawm nitrocellulose siv yog qis dua 12.60%. Tshwj xeeb tshaj yog thaum tov nrog detonators thiab ib leeg-hauv paus phom phom, kev nyab xeeb thiab ruaj khov ntawm tus“multi-base explosives”yog neeg pluag heev. Muaj ntau yam xwm txheej kev nyab xeeb uas tau tshwm sim thoob plaws hauv lub tebchaws hauv peb lub xyoos dhau los yog qhov kev mob siab rau. Ntxiv txwv tsis pub oxidants tuaj yeem ua txhaum lossis ua txhaum cai. Yog li ntawd, piv nrog rau peb hom explosives,ob lub hauv paus explosives yog superior thiab muaj kev ruaj ntseg thiab stability ntau dua.
Qhov tshwm sim
2.1 Cov tsos ntawm ob lub ntsiab lus tawg ua ke ntawm cov ntsia hlau yog me ntsis tsaus dua.
2.2 Cov ntsia hlau sib xyaw ntawm nitrocellulose thiab "multi-based explosives "muaj lub ntsej muag huv si thiab tsis muaj impurities, nrog cov xim liab thiab dawb txawv.
2.3 Qhov tawg ntawm binary explosive integrated ntsia hlau yog nyob rau hauv daim ntawv ntawm granules.
2.4 Nitrocellulose thiab thiaj li hu ua“multi-based explosive”Cov ntsia hlau sib xyaw feem ntau yog cylindrical.
Kev ua tau zoo
Piv nrog rau lwm yam ob hom, kev tsim cov nqi ntawm binary explosive integrated rau tes yog me ntsis siab dua, tab sis nws txoj kev nyab xeeb thiab kev ua tau zoo yog qhov zoo tshaj plaws, feem ntau xav txog plaub yam nram qab no.
3.1 Nws muaj lub zog loj, zoo sib xws, kev ua haujlwm ruaj khov thiab kev siv dav dav. Nws tuaj yeem ua tau raws li ntau yam kev siv ib puag ncig, tshwj xeeb tshaj yog cov xwm txheej muaj zog, ua rau nws xaiv qhov zoo tshaj plaws.
3.2 Kev nyab xeeb siab, lub detonator nyob rau hauv qab ntawm lub plhaub thiab yuav tsum tau ib txoj kev tshwj xeeb rau detonate. Txawm li cas los xij, qhov uas twb muaj lawm hu ua“ntau-raws li explosives”ntxiv detonator Cheebtsam rau cov khoom tawg, uas yuav tsum tau ntau lawm ntau lawm, tsheb thauj mus los, cia thiab siv. Txhua yam extrusion lossis cuam tshuam thaum cov txheej txheem no yuav ua rau muaj kev nyab xeeb loj thiab ua rau muaj kev phom sij loj.
3.3 Cov khoom muaj kev ruaj ntseg zoo.ob lub hauv paus explosives muaj cov dej noo tsis tshua muaj siab, tsis txhob nqus dej noo hauv huab cua, thiab yuav luag tsis muaj hluav taws kub. Tus hu“ntau-raws li explosives”yog hygroscopic heev thiab tsis tuaj yeem detonate, ua rau misfires. Vim yog cov tshuaj tiv thaiv exothermic uas tshwm sim thaum ya raws yog absorbed, muaj kev txaus ntshai ntawm spontaneous combustion nyob rau hauv tej yam kub kub.
3.4ob lub hauv paus explosives tshwj xeeb tshaj yog tus phooj ywg rau cov ntsia hlau phom, tsis txhob corrode, thiab tsis picky txog cov cuab yeej, thaum hu ua“multi-base explosives”hnyav corrode ntsia thawv phom thiab ua rau cov cuab yeej siv tsis tau, yog li cuam tshuam rau kev tsim kho thiab nce nqi. Qhov phom sij tshaj plaws yog corrosion ntawm cov ntsia hlau thiab hlau hangers. Tus yuam sij rau txhua lub hom phiaj kev siv fastening yog cov kav ntev thiab lub sijhawm ntawm cov ntsia hlau thiab hlau hangers. Vim yog corrosion, nws yog ib qho yooj yim rau vau los yog poob, ua rau poob ntawm cov khoom los yog txawm lub neej, uas yog tantamount rau ib tug ua txhaum cai!
Xaus
Thoob plaws hauv keeb kwm ntawm kev txhim kho riam phom thiab mos txwv nyob ib ncig ntawm lub ntiaj teb no, cov primer + explosive shooting txoj kev tseem yog cov txheej txheem niaj hnub tshaj plaws ntawm noob neej. Lwm txoj hauv kev, xws li kev sib txuas cov detonators nrog cov khoom tawg, tsis muaj kev tshawb fawb thiab kev ua tau zoo. Vim nws cov yam ntxwv ntawm tus kheej,ob lub hauv paus explosives tau raug pov thawj rau ntau pua xyoo thiab tseem irreplaceable nyob rau hauv cov nqe lus ntawm kev nyab xeeb, stability thiab kev cia siab rau.
Yog li ntawd, xaiv ob lub hauv paus tawgkev koom ua ke rau tes yog qhov koj xaiv zoo tshaj plaws thiab txawj ntse tshaj plaws!
