Ukuphendula lo mbuzo, kufuneka siqale siqonde ukuba yintoni ugqabhuko-dubulo? Kwaye yintoni i-foam yesinyithi?
1. Iziqhushumbisi zahlulwe ubukhulu becala zibe ziziqhushumbisi ezibonakalayo nezekhemikhali
- Umgaqo wokudubula komzimba:
Ukuqhuma komzimba kubangelwa utshintsho lomzimba (njengobushushu, umthamo, uxinzelelo, njl.), kunye neempawu kunye nokwakheka kweekhemikhali zezinto eziqhumayo azitshintshi ngaphambi nangemva kokuqhuma.
Amandla ogqabhuko lwezinto eziphathekayo aphuma ikakhulu kumandla acuthekayo, amandla enguqu yesigaba, amandla ekinetic, amandla okuqukuqela, amandla ashushu, amandla ombane, njl.
Uxinzelelo olugqithisileyo lwenkqubo yegesi engeyiyo yekhemikhali, ukuqhuma kwegesi yolwelo, ugqabhuko-dubulo lwerhasi enyibilikisiweyo kunye nolwelo olushushu kakhulu, ubushushu bokunyibilika, ubushushu bokudityaniswa, ubushushu be-adsorption, ugqabhuko-dubulo olubangelwa kukufudumeza kwangaphandle, ugqabhuko-dubulo olubangelwa kukuqukuqela ulwelo, ugqabhuko-dubulo olubangelwa kukudlula. , ugqabhuko-dubulo olubangelwa yindawo yokukhupha Ukudubula komoya konke kudidi lodubulo olubonakalayo.
- Imigaqo yokudubula kweekhemikhali:
Iziphumo zeMichiza zivela kwiimpendulo zeekhemikhali.
Ingaba ngumxube wezinto ezinokutsha kunye nomoya, okanye i-explosive (efana ne-dynamite), i-substance of chemical explosion yinkqubo engazinzanga, eya kuba ne-reaction exothermic enobudlova phantsi kwesenzo samandla athile angaphandle. , ukuvelisa ukushisa okuphezulu kunye noxinzelelo oluphezulu, kwaye uvelise umphumo onamandla owonakalisayo.
- Le miqathango mihlanu ilandelayo kufuneka ifezekiswe:
A. Izinto ezinokutsha ezibonelela ngamandla, oko kukuthi, iziqhushumbisi;
B. I-accelerants yokutshisa (i-oxidants), njenge-oxygen, umoya;
Izinto ezinokutsha kunye ne-accelerant zixutywe ngokulinganayo;
D. Umxube ubekwe kwindawo evaliweyo (ejikelezwe);
Khanyisa unikezelo lwamandla olwaneleyo.
2. Yintoni igwebu lesinyithi?
I-Metal foam luhlobo lwetsimbi ene-porous ene-porosity engaphezu kwe-90% kunye namandla athile kunye nobunzima. Le mveliso yintsimbi equlethe i-foam ye-pore, i-porosity iphezulu kuneyentsimbi eqhelekileyo ene-sintered, kwaye ubukhulu bepore bunokufikelela kwi-7 mm.
I-foam ye-Metal yinto edibeneyo yesigaba sesibini esakhiwe nge-pore dispersed phase kunye ne-metal matrix skeleton isigaba esiqhubekayo kunye nesigaba, kwaye iimpawu zayo zixhomekeke kwimpembelelo ye-metal matrix, i-porosity, isakhiwo se-pore kunye nenkqubo yokulungiselela.
3. Isinyithi esinegwebu sisetyenziswa kwisithinteli-mlilo esingagqabhukiyo
I-Metal foam inokugqithiselwa kakuhle kolwelo kunye nokumelana nomlilo okulungileyo. Ingafakwa kwimibhobho ethwele iigesi ezinokutsha okanye ulwelo ukumisa ugqabhuko-dubulo ngokufunxa ubushushu ukunqanda ukusasazeka kwamadangatye.
Le mveliso ilungele i-acetylene, i-oxygen flame gas welding kunye ne-gas cutting technology, ii-motor mining kunye nokutshintsha kwamandla, ukucocwa kwe-oyile kunye nemibhobho yegesi evuthayo, iinkqubo zokutshisa i-oyile kunye ne-gas recovery systems, iziko lokufudumeza, iinkqubo zokucoca igesi, njl njl. zisetyenziswe njengesithako esingatshiyo kunye nesingagqabhukiyo kwiitanki zokugcina ezifana nerhasi enyibilikisiweyo nezibaso.
