Ukuze siphendule lo mbuzo, kufanele siqale siqonde ukuthi kuyini ukuqhuma? Futhi yini igwebu lensimbi?
1. Iziqhumane zihlukaniswe kakhulu zibe iziqhumane ezibonakalayo namakhemikhali
- Umgomo wokuqhuma komzimba:
Ukuqhuma komzimba kubangelwa izinguquko zomzimba (ezifana nezinga lokushisa, ivolumu, ingcindezi, njll.), futhi izakhiwo kanye nokwakheka kwamakhemikhali ezinto eziqhumayo akushintshi ngaphambi nangemva kokuqhuma.
Amandla okuqhuma okubalulekile avela kakhulu emandleni okuncipha, amandla okushintsha kwesigaba, amandla e-kinetic, amandla okugeleza, amandla ashisayo, amandla kagesi, njll.
Ukuqhuma ngokweqile kwegesi okungewona amakhemikhali, ukuqhuma kwegesi ewuketshezi, ukuqhuma kwegesi ewuketshezi noketshezi olushisa kakhulu, ukushisa kokuncibilika, ukushisa kwe-dilution, ukushisa kwe-adsorption, ukuqhuma okubangelwa ukushisa kwangaphandle, ukuqhuma okubangelwa uketshezi olugelezayo, ukuqhuma okubangelwa i-overcurrent. , ukuqhuma okubangelwa indawo yokukhipha Ukuqhuma komoya konke kungokwesigaba sokuqhuma komzimba.
- Izimiso zokuqhuma kwamakhemikhali:
Imiphumela yamakhemikhali ivela ekuphenduleni kwamakhemikhali.
Kungakhathaliseki ukuthi ingxube yezinto ezivuthayo nomoya, noma ukuqhuma (okufana ne-dynamite), into yokuqhuma kwamakhemikhali isistimu engazinzile, ezobhekana nokusabela okunamandla kwe-exothermic ngaphansi kwesenzo samandla athile angaphandle. , ukukhiqiza izinga lokushisa eliphezulu nokucindezela okukhulu, futhi ukhiqize umphumela onamandla owonakalisayo.
- Kufanele kuhlangatshezwane nemibandela emihlanu elandelayo:
A. Izinto ezivuthayo ezinikeza amandla, okungukuthi, iziqhumane;
B. Ama-accelerants omlilo (ama-oxidants), njenge-oxygen, umoya;
Into evuthayo kanye ne-accelerant ixubene ngokulinganayo;
D. Ingxube ibekwe endaweni evalekile (ezungezwe);
Khanyisa amandla amaningi.
2. Iyini igwebu lensimbi?
I-Metal Foam iwuhlobo lwensimbi enezimbotshana ene-porosity engaphezu kuka-90% namandla athile nobulukhuni. Lo mkhiqizo uyingxenye yensimbi equkethe i-pore foam, i-porosity iphakeme kuneyensimbi evamile ene-sintered, futhi ubukhulu bembobo bungafinyelela ku-7 mm.
I-Metal Foam iyinhlanganisela yezigaba ezimbili ezakhiwe isigaba esihlakazekile se-pore kanye nesigaba se-metal matrix skeleton esiqhubekayo nesigaba, futhi izakhiwo zayo zincike ethonyeni le-metal matrix, i-porosity, isakhiwo se-pore kanye nenqubo yokulungiselela.
3. Igwebu lensimbi lisetshenziswa ekunqandeni amalangabi angaqhumi
Igwebu lensimbi linokungena kahle koketshezi kanye nokumelana nomlilo okuhle. Ingafakwa emapayipini athwala amagesi avuthayo noma uketshezi ukumisa ukuqhuma ngokumunca ukushisa ukuze kumiswe ukusabalala kwamalangabi.
Lo mkhiqizo ulungele i-acetylene, i-oxygen flame gas welding kanye nobuchwepheshe bokusika igesi, izinjini zezimayini kanye nokushintshwa kwamandla, ukucwenga uwoyela namapayipi egesi avuthayo, amasistimu okushisa, amasistimu okubuyisela uwoyela negesi, iziko lokushisa, izinhlelo zokuhlanza igesi, njll. isetshenziswe njengesicwebi esingangenwa umlilo nesingaqhumisi amathangi okugcina njengegesi eliwuketshezi nophethiloli.
