Momwe Mungagwiritsire Ntchito Dry Ice Blasting Malo Oyera？

Dry ice blasting ndi njira yophulika yomwe imagwiritsa ntchito mapepala owuma a ayezi ngati njira yophulitsira. Ubwino wogwiritsa ntchito ma pellets owuma ngati kuphulika kwa media ndikuti samatulutsa tinthu tambiri tomwe timatulutsa tinthu tating'onoting'ono tikugwira ntchito. Ubwinowu umapangitsanso kuti kuphulika kwa ayezi kukhale njira yabwino yoyeretsera.

Kodi abrasive amapanga bwanji?

1.     Gawo loyamba: CO2 yamadzimadzi imatulutsa ayezi wowuma pansi pa decompression mwachangu. Kenako idzapanikizidwa kukhala ma pellets ang'onoang'ono osakwana madigiri 79.

2.     Panthawi yowuma ya ayezi, mpweya woipa wa carbon dioxide umalowa mu cylinder yokakamiza ya pelletizer. Ndi kuthamanga kwa pelletizer, madzi a carbon dioxide amasanduka matalala owuma.

3.     Kenako chipale chofewa chowuma chimakanikizidwa kudzera mu mbale ya extruder kenako ndikupanga ndodo youma ya ayezi.

4.     Chomaliza ndikuphwanya timitengo ta ayezi touma kukhala ma pellets.

Masamba owuma a ayezi nthawi zambiri amayezedwa 3 mm m'mimba mwake. Panthawi yophulitsa, imatha kudulidwa kukhala tizidutswa tating'ono.

Pambuyo pomvetsetsa momwe madzi owuma amapangira madzi oundana, tiyeni tidziwe zambiri za momwe tingawagwiritsire ntchito poyeretsa malo.

Kuwuma kwa ayezi kumakhala ndi zotsatira zitatu:

1.     Kinetic mphamvu:Mu physics, mphamvu ya kinetic ndi mphamvu yomwe chinthu kapena tinthu tating'ono timakhala ndi chifukwa cha kuyenda kwake.

 Njira yowuma ya ayezi imatulutsanso mphamvu ya kinetic pamene tinthu tating'ono ting'onoting'ono ta madzi oundana tagunda pa chandamalepansi pa kuthamanga kwambiri. Ndiye nthumwi zouma khosi zidzaphwanyidwa. Kuuma kwa Mohs kwa ma pellets owuma a ayezi kumakhala kofanana ndi pulasitala. Choncho, imatha kuyeretsa pamwamba bwino.

2.     Mphamvu yotentha:mphamvu yotentha imatha kutchedwanso mphamvu ya kutentha. Kutentha kwamphamvu kumayenderana ndi kutentha. Mu physics, mphamvu yomwe imachokera ku kutentha kwa chinthu chotenthedwa ndi mphamvu yotentha.

Monga tanena kale, co2 yamadzimadzi imapanikizidwa kukhala ma pellets ang'onoang'ono paminus 79 degrees. Pochita izi, kutentha kwa kutentha kumapangidwa. Ndipo pamwamba pa zinthu zomwe ziyenera kuchotsedwa zidzawonetsa ming'alu yabwino. Pakakhala ming'alu yabwino pamwamba pa zinthuzo, pamwamba pake pamakhala ming'alu komanso yosavuta kusweka.

3.     Chifukwa cha kugwedezeka kwa kutentha, ma carbon dioxide ena oundana amalowa m'ming'alu ya dothi ndikutsitsa pansi. The sublimates achisanu mpweya carbon dioxide chifukwa buku la izo chawonjezeka ndi chinthu cha 400. The kuchuluka voliyumu wa mpweya woipa akhoza kuphulitsa zigawo dothi izi.

Zotsatira zitatu izi zimapangitsa kuti kuphulika kwa ayezi kutha kuchotsa utoto wosafunikira, mafuta, mafuta, zotsalira za silicon, ndi zina. Umu ndi momwe kuphulika kwa ayezi kowuma kumatsuka pamwamba.
