Chithovu cha aluminiyamu chimapezeka posakaniza ufa wa aluminiyamu wa alloy ndi chinthu cholekanitsidwa panthawi ya kutentha ndi mpweya. Iwo ali ndi makhalidwe a kulemera kuwala, mkulu porosity ndi mkulu enieni pamwamba dera. Ili ndi mawonekedwe onse azitsulo zachitsulo ndi thovu, ndipo imakhala ndi mphamvu yotsutsa kwambiri, mphamvu yeniyeni yeniyeni, kukana kutentha kwakukulu, kukana moto wamphamvu, komanso imakhala ndi chitetezo champhamvu chamagetsi ndi zosefera. Lero, tikuwonetsa zabwino zisanu ndi ziwiri za kuyesa kwa thovu la aluminium mwatsatanetsatane.

1. Kuyang'ana thovu la aluminiyamu - kusanthula magwiridwe antchito
Chinthu chachikulu chopangidwa ndi chithovu cha aluminiyamu ndi chakuti chimakhala ndi pores ambiri mkati, zomwe zimapangitsa kuti zikhale zopepuka komanso zolemera kwambiri. Chifukwa cha izi, chithovu cha aluminiyamu chimakhala chodzaza masangweji abwino kwambiri pamapanelo ophatikizika a masangweji, omwe amawongolera kwambiri mawonekedwe azinthu zophatikizika zomwe zimapakidwa, kotero kuti kukana kwake kupindika, mphamvu yopondereza, ndi kuthekera kwa mayamwidwe a phokoso zimatheka. kuwongolera kogwira mtima. Poyerekeza ndi masangweji achikale a zisa, zinthu za aluminiyamu zokhala ndi thovu zimachepetsa mtengo ndikuthana ndi vuto la anisotropy la masangweji a uchi.

2. Kuzindikira za aluminiyumu thovu - kusanthula ntchito mayamwidwe mphamvu
Njira kuchokera ku mphamvu kupita ku kukanikizana kwa zinthu za thovu imagawidwa m'magawo atatu, gawo loyamba ndi siteji ya zotanuka. Pambuyo pa kupsinjika, ma pores amkati azinthu zotayidwa thovu amatha kusinthanso zotanuka. Gawo lachiwiri ndi gawo lopanga nsanja. Pamene mawotchi mphamvu ya thovu zotayidwa zakuthupi kufika pa Irrecoverable mlingo, akulowa akuumba mapindikira siteji. Panthawiyi, ma pores amkati amatha kusinthika monga kulolera ndi kukwawa, ndipo pamapeto pake amagwa kwathunthu. Pamene mlingo wa kugwa kufika kukhudzana pakati pa pore makoma osiyana, izo amalowa gawo lachitatu: kachulukidwe siteji. Chifukwa chake, chithovu cha aluminiyamu chikakakamizidwa, chimakhala ndi chikhalidwe chapadera cha kupanikizana. Pochita izi, kupanikizika kumasandulika kukhala mphamvu ya foam deformation, yomwe imagwira bwino mphamvu ya mphamvu yowonongeka.

3. Kuzindikira chithovu cha aluminiyamu - kusanthula magwiridwe antchito a shock
Aluminiyamu yokhala ndi thovu imakhala ndi zonyowa kwambiri, nthawi 5 mpaka 10 kuposa ya aluminiyamu yoyera. Chikhalidwe ichi chimagwirizana ndi porosity, kukula kwa pore ndi matalikidwe amtundu wa aluminium thovu lokha. Kukwera kwa porosity, kucheperachepera kwa pore ndikukulirakulira kwa kupsyinjika, kumapangitsanso kuti thovu la aluminiyamu likhale lonyowa.

Pamene zinthu za aluminiyamu zokhala ndi thovu zimakhudzidwa ndi kupsinjika kwakunja, chifukwa cha ma pores osagwirizana, kugawa kwamphamvu kwapang'onopang'ono kumakhalanso kosagwirizana, kotero kuti mphamvu yowonongeka imasandulika kukhala kumeta ubweya wa ubweya, yomwe imawononga kupsinjika kwa kunja ndikusandulika kukhala mphamvu yotentha mkati mwa zitsulo zotayidwa thovu . Malinga ndi mawonekedwe awa a aluminiyamu yokhala ndi thovu, zinthu za aluminiyamu zopangidwa ndi thovu zimakhala chinthu chabwino kwambiri chododometsa. Monga ma bumpers agalimoto, zida zotsikira m'mlengalenga, ndi zina.

4. Kuyesa kwa aluminium thovu - kusanthula kamvekedwe ka mawu
Mapangidwe apadera a pore a aluminiyumu thovu amapangitsa kuti azikhala ndi mawu abwino oyamwa. Phokoso likadutsa mu pore, limayambitsa kumveka kwa phokoso mu pore, ndipo kukangana ndi khoma la pore kumapanga mphamvu ya kutentha, ndipo mphamvu ya kutentha imatayidwa kudzera mu aluminiyamu, kotero kuti mapangidwe a pore a aluminiyamu amatulutsa thovu bwino. amayamwa phokoso. Kumveka kwa mayamwidwe a aluminiyamu yokhala ndi thovu kumawonjezeka ndi kuwonjezeka kwa porosity, kuchepa kwa pore kukula komanso kuchuluka kwa makulidwe azinthu. Malinga ndi mayamwidwe amtundu wa aluminium thovu, amagwiritsidwa ntchito kwambiri m'ma studio ojambulira pawayilesi komanso zida zamaofesi.

5. Kuzindikira thovu la aluminiyamu - kusanthula magwiridwe antchito a electromagnetic shielding
Kafukufuku ndi kuyezetsa zikuwonetsa kuti zinthu za aluminiyamu zopangidwa ndi thovu zimakhala ndi chitetezo chabwino chamagetsi. Mphamvu ya maginito yothamanga kwambiri ikadutsa mu thovu, mphamvu ya maginito yomwe ilipo imapangidwa mkati mwa thovulo, lomwe limalepheretsa mphamvu ya maginito yoyambirira. Malinga ndi ntchitoyi, zida za aluminiyamu zopangidwa ndi thovu zimagwiritsidwa ntchito kuchipinda chamagetsi ndi zida zamagetsi,

Muzinthu zotetezera zida zamagetsi.

6. Kuzindikira zinthu za aluminiyamu thovu - kusanthula kusinthana kwa kutentha ndi ntchito ya kutentha kwa kutentha
Chifukwa chakuti zitsulo za aluminiyumu za thovu zimakhala ndi thovu zambiri za mpweya zomwe zimakhala ndi mphamvu zochepa zowonongeka, kutentha kwake sikuli kofanana ndi aluminium, koma ndikwabwino kwambiri kuposa mapulasitiki a thovu. Kutentha kwake kwa matenthedwe kumakhudzidwa ndi porosity, ndipo kumtunda kwa porosity, kumakhala koipitsitsa kwambiri. Pansi pa zochitika zachilengedwe, kutentha kumatayidwa ndi kusinthana kwa kutentha pakati pa mpweya kapena madzi ndi makoma a pore. Izi zimapangitsa chithovu cha aluminiyamu kukhala kusinthana kwabwino kwa kutentha kapena zinthu zotayira kutentha. Mwachitsanzo, chipangizo cha deicing chimayikidwa kutsogolo kwa mapiko a ndege, ndipo gasi wotenthetsera kapena antifreeze amatulutsidwa kuchokera ku aluminiyumu yopangidwa ndi thovu kuti akwaniritse cholinga cha deicing.

7. Kuzindikira chithovu cha Aluminium - kusefedwa kwa magwiridwe antchito
Chifukwa permeability a thovu zotayidwa, angagwiritsidwe ntchito ngati zinthu zabwino fyuluta m'minda zamoyo ndi mankhwala. Ma pores omwe ali mu aluminiyumu thovu amakhala ndi kusefa kwabwino komanso kulekanitsa pamagasi kapena zakumwa, komanso amatha kusefa zolimba za mpweya.
