Aluminiyamu yopangidwa ndi thovu imapangidwa powonjezera zowonjezera ku aluminiyamu yoyera kapena aloyi ya aluminiyamu kudzera mukupanga thovu, ndipo imakhala ndi zitsulo zonse ndi kuwira. Imakhala ndi kachulukidwe kakang'ono, mphamvu yoyamwa kwambiri, kukana kutentha kwambiri, kukana kwamphamvu kwamoto, kukana dzimbiri, kutsekereza phokoso ndi kuchepetsa phokoso, kutsika kwamafuta, kutchinga kwamphamvu kwamagetsi, kukana kwamphamvu kwa nyengo, kuthekera kosefera, kukonza kosavuta, kuyika kosavuta, komanso kukweza kwambiri. kupanga kulondola , Kupaka pamwamba kumatha kuchitika.

Aluminiyamu thovu ndi mtundu watsopano wa zinthu zopepuka zachitsulo zopangidwa ndi aluminium alloy thovu. Ili ndi kachulukidwe kakang'ono komanso mphamvu zambiri zapadera. Lili ndi zinthu zambiri zabwino kwambiri monga kuyamwa kwamawu ndi kutsekereza mawu, kuyamwa mphamvu ndi kutsamira, kuletsa moto komanso kusaphulika. Amagwiritsidwa ntchito kwambiri muzamlengalenga zankhondo, zoyendera njanji, kupanga zombo, ndi zina. Pakati pa "Zapamwamba Khumi Zomwe Zingatheke Kwambiri Zatsopano M'tsogolomu" zosankhidwa ndi atolankhani akunja, zinthu za aluminium thovu zili pa nambala 6.

Titha kusintha mbiri ya aluminiyamu ya thovu yokhala ndi ma apertures osiyanasiyana, makulidwe ndi zofunikira malinga ndi kapangidwe kake.

1. Makhalidwe amachitidwe

① Opepuka: Kachulukidwe ndi 0.1-0.4 nthawi ya aluminiyamu yachitsulo;

② Kuuma kwapadera kwapadera: kuuma kwake kwapadera ndi nthawi 1.5 kuposa chitsulo;

③ Kuchuluka kwamphamvu kwamayamwidwe owopsa komanso kuchuluka kwa mayamwidwe amphamvu:magwiridwe antchito ndi5-10nthawi ya aluminiyamu yachitsulo. Porosity Pamene chithovu cha aluminiyamu chokhala ndi mlingo wa 84% chapunduka ndi 50%, chimatha kuyamwa mphamvu zoposa 2.5MJ/cm3.

④ Ubwino wamayimbidwe ntchito: 1. Phokoso kutchinjiriza ntchito (yotsekedwa selo): PameneKuthamanga kwa phokoso kumakhala pakati pa 800-4000HZ, Kutsekemera kwa phokoso kwa thovu la aluminiyamu yotsekedwa ndi pamwamba pa 0.9. 2. Mayamwidwe amawu (kang'ono kudzera m'mabowo ndi m'mabowo): Mafunde amphamvu akakhala pakati pa 125 mpaka 4000HZ, mphamvu yoyamwa kwambiri ya thovu la aluminiyamu yodutsa m'bowo imatha kufika pa 0.8, ndipo pafupifupi mayamwidwe a phokoso la bandi ya octave kuposa 0.4.

⑤ Kuchita bwino kwambiri kwachitetezo chamagetsi: pomwe ma frequency a electromagnetic wave ali pakati pa 2.6-18GHZ, ma elekitiromaginito, kuchuluka kwachitetezo kumatha kufika 60-90dB.

⑥ Matenthedwe abwino: Kutentha kwa thovu la aluminiyamu yotsekeka yokhala ndi porosity ya 80-90% ndi 0.3-1W/m#8226;k, yofanana ndi nsangalabwi. Chithovu cha aluminiyamu chodutsa m'bowo chimakhala ndi ntchito yabwino yochotsa kutentha pansi pamikhalidwe yokakamiza chifukwa cholumikizana ndi pores.

⑦ sichiyaka ndipo imalimbana bwino ndi kutentha. □ Kuchita bwino kwa dzimbiri, kukana nyengo, kuyamwa kwa chinyezi chochepa, kusakalamba, Kupanda poizoni.

⑧ Yosavuta kukonza: yabwino kudula, kubowola, ndi simenti; imatha kupindika mu mawonekedwe ofunikira poumba; itha kugwiritsa ntchito organic kapena Inorganic utoto ntchito pamwamba mankhwala; imatha kukumbidwa mbali zonse ziwiri kuti apange bolodi lalikulu lopepuka, lolimba kwambiri. Kukula kwanthawi zonse: 600x1200x5/10MM, 500x1000x5/10MM.

⑨ Kuyika kosavuta: Zinthu za aluminiyamu zokhala ndi thovu zimatha kukhazikitsidwa pamalo okwera popanda zida zonyamulira zamakina, monga: denga, makoma ndi madenga, ndi zina zotero, zimatha kulumikizidwa ndikukhazikitsidwa ndi njira zamakina kapena mwachindunji ndi zomangira, kapena zimatha amamatiridwa pakhoma kapena padenga ndi zomatira.

⑩ Mapangidwe a "sangweji" opangidwa ndi chitsulo chochepa kwambiri chachitsulo-aluminium chithovu - mbale yachitsulo yopyapyala imatenga zabwino zamtundu wa aluminiyamu thovu ndi mphamvu yopindika kwambiri, zitha kugwiritsidwa ntchito ngati zida zomangira zatsopano, zida zomangira zolimba kwambiri, ndi zina.

2. Mapangidwe ake

• Khomo lalikulu ndi 0.3-7mm;
• High ndi controlable porosity: 63% -90%;
• Malo enieni ndi 10—45cm2/cm3;
• Mitundu yosiyanasiyana ya maselo; otsekedwa selo, kudzera mu selo ndi yaying'ono kudzera mu cell aluminium thovu;
• Mapangidwe ndi mapangidwe a pore a chimango chachitsulo amatha kuwongolera, omwe angagwirizane ndi zosowa zosiyanasiyana.

3. Kuchuluka kwa ntchito

Mayamwidwe amawu ndi zida zotchinjiriza mawu: aluminiyumu yokhala ndi thovu imatha kugwiritsidwa ntchito powongolera phokoso la njanji zowunikira zam'tawuni, misewu yayikulu, ngalande zapansi panthaka, zida zamakina, komanso kukonza zipinda zomvera, maholo okhala ndi ntchito zambiri ndi zomveka zina zamkati. Chithovu cha aluminiyamu chomamva mawu chimamatidwa ku konkriti kapena chitsulo ndikumangika mbali zonse ziwiri za ma viaducts ndi njanji zopepuka ngati makoma akulu akulu otulutsa mawu, zomwe zimatha kuchepetsa phokoso lamayendedwe akumizinda. Phokoso la aluminiyumu lopangidwa ndi thovu lingagwiritsidwe ntchito podzipatula phokoso m'zipinda zamakompyuta zamafakitale, makina ndi zida, ndi malo omanga panja, ndikuthana ndi zolephera zambiri zomwe zimagwiritsidwa ntchito kwambiri potengera mawu monga ubweya wagalasi ndi asibesitosi.

4. Malo ogwiritsira ntchito

aluminiyumu yokhala ndi thovu imatha kupanga mawonekedwe ofunikira posintha makulidwe ake ndi kapangidwe ka pore. Ichi ndi chithumwa cha zinthu zapaderazi. Choncho, amagwiritsidwa ntchito kwambiri m'madera ambiri.
