Kuti tiyankhe funsoli, choyamba tiyenera kumvetsetsa kuti kuphulika n’chiyani? Ndipo thovu lachitsulo ndi chiyani?
1. Zophulika zimagawidwa makamaka kukhala zophulika zakuthupi ndi zamankhwala
- Mfundo ya kuphulika kwa thupi:
Kuphulika kwa thupi kumayambitsidwa ndi kusintha kwa thupi (monga kutentha, voliyumu, kupanikizika, etc.), ndipo katundu ndi mankhwala opangidwa ndi zinthu zophulika sizisintha kusanachitike komanso pambuyo pa kuphulika.
Mphamvu za kuphulika kwa zinthu zimachokera ku mphamvu ya shrinkage, mphamvu ya kusintha kwa gawo, mphamvu ya kinetic, mphamvu yothamanga, mphamvu yotentha, mphamvu yamagetsi, ndi zina zotero.
Kuphulika kwakukulu kwa gasi wopanda mankhwala, kuphulika kwa gasification yamadzimadzi, kuphulika kwa gasi wonyezimira ndi madzi otentha kwambiri, kutentha kwa kutentha, kutentha kwa dilution, kutentha kwa adsorption, kuphulika komwe kumayambitsidwa ndi kutentha kwakunja, kuphulika kwa madzi othamanga, kuphulika kwa madzi ochuluka. , kuphulika komwe kumachitika chifukwa cha malo otayira Kuphulika kwa mpweya zonse zili m'gulu la kuphulika kwakuthupi.
- Mfundo za kuphulika kwa mankhwala:
Zotsatira za mankhwala zimachokera ku zochitika za mankhwala.
Kaya ndi chisakanizo cha zoyaka zoyaka ndi mpweya, kapena zophulika (monga dynamite), chinthu cha kuphulika kwa mankhwala ndi dongosolo losakhazikika, lomwe lidzakumana ndi chiwawa chachiwawa choopsa pansi pa mphamvu inayake yakunja. , kutulutsa kutentha kwakukulu ndi kuthamanga kwakukulu, ndipo kumatulutsa zotsatira zowononga kwambiri.
- Zinthu zisanu zotsatirazi ziyenera kukwaniritsidwa:
A. Zinthu zoyaka zomwe zimapereka mphamvu, ndiko kuti, zophulika;
B. Kuwotcha accelerants (oxidants), monga mpweya, mpweya;
Zomwe zimayaka ndi accelerant zimasakanizidwa mofanana;
D. Kusakaniza kumayikidwa mu malo otsekedwa (ozungulira);
Yatsani mphamvu zokwanira.
2. Kodi thovu lachitsulo ndi chiyani?
Chithovu chachitsulo ndi mtundu wazitsulo zaporous ndi porosity yoposa 90% ndi mphamvu zina ndi kuuma. Izi ndi zinthu zachitsulo munali pore thovu, porosity ndi apamwamba kuposa wamba sintered porous zitsulo, ndi pore kukula akhoza kufika 7 mm.
Chithovu chachitsulo ndi gawo la magawo awiri opangidwa ndi pore obalalika gawo ndi zitsulo masanjidwewo mafupa mosalekeza gawo ndi gawo, ndipo katundu wake zimadalira mphamvu ya zitsulo masanjidwewo, porosity, pore kapangidwe ndi ndondomeko kukonzekera.
3. Chithovu chachitsulo chimagwiritsidwa ntchito poletsa kuphulika kwa malawi
Chithovu chachitsulo chimakhala ndi mpweya wabwino wamadzimadzi komanso kukana moto. Itha kuikidwa m'mapaipi onyamula mpweya woyaka kapena zamadzimadzi kuti aletse kuphulikako potengera kutentha kuletsa kufalikira kwa malawi.
Mankhwalawa ndi oyenera acetylene, kuwotcherera kwa mpweya wamoto wa okosijeni ndi ukadaulo wodula gasi, makina opangira migodi ndi masiwichi amagetsi, kuyenga mafuta ndi mapaipi oyaka moto, makina oyaka, makina obwezeretsa mafuta ndi gasi, ng'anjo zotentha, makina oyeretsera mpweya, ndi zina zotero. Agwiritsidwe ntchito ngati chotchinga moto komanso choletsa kuphulika kwa matanki osungiramo monga gasi wamadzimadzi ndi mafuta.
