Chithovu chamkuwa ndi chinthu cha porous chopangidwa kuchokera ku chisakanizo cha zitsulo zamkuwa ndi zinthu zotulutsa thovu pamwamba, zomwe zimawotchedwa ndikukulitsidwa pa kutentha kwakukulu. Mu ng'anjo yotentha, thovu lamkuwa ndilosavuta kutulutsa mpweya mumlengalenga chifukwa mamolekyu a okosijeni amatha kulowa mkati mwa thovu kudzera m'mitsempha ya thovu ndikuchitapo kanthu ndi mkuwa kuti apange oxide yamkuwa.

Ceramic thovu fyuluta akhoza bwino kusokoneza inclusions mu zitsulo zamadzimadzi ndi kusintha khalidwe kuponyera ndi zokolola, ceramic thovu fyuluta ali ndi njira zinayi zazikulu kuyeretsa bwino zitsulo madzi.

Kumanga zotchinga zomveka kumbali zonse ziwiri za msewu waukulu ndi njira yabwino yopewera ndikuwongolera kuipitsidwa kwa phokoso lamisewu, zotchinga zomveka zokhala ndi kutalika kokwanira, kutalika, nthawi zambiri, zimatha kuchepetsa phokoso la 10-15dB. Ngati mukufuna kuwongolera kuchuluka kwa kuchepetsa phokoso, muyenera kukhala mu kapangidwe ndi kapangidwe ka zotchinga zomveka, kuti muwongolere.

Silicon carbide ceramics ikupanga mafunde m'munda wa zida zapamwamba ndi magwiridwe ake apamwamba komanso ntchito zambiri. Kuchokera kumadera otentha kwambiri kupita kumalo owononga komanso owononga, zoumba za silicon carbide zatsimikizira kukhala zosankha zambiri komanso zodalirika m'mafakitale osiyanasiyana.

M'nkhani zaposachedwa, ntchito yomanga ndi yodabwitsa chifukwa cha kupezeka kwa zinthu zosagwira moto - thovu la aluminiyamu. Zinthu zatsopanozi zimatha kusintha momwe timayendera chitetezo chamoto m'nyumba, kupatsa okonza ndi okhalamo chitetezo chatsopano komanso mtendere wamalingaliro.

Silver thovu ndi mtundu watsopano wa zinthu zinchito ndi mkulu porosity, lalikulu enieni pamwamba m'dera, ndi permeability wabwino, etc. Kugwiritsa ntchito ngati chothandizira ali ndi ubwino wa ntchito mkulu, bata wabwino, ndi kusankha bwino, zomwe zimapangitsa kukhala m'malo abwino kwa zida zasiliva zomwe zilipo.

Kuyika kwa zinthu za aluminium thovu ndikosavuta komanso kosavuta:
Masitepe oyika khoma aperekedwa: kupachika kowuma → keel yaikulu → vice keel → mbale yopachika kapena misomali yodzigunda yokha pamodzi ndi kumata );
Chifukwa gulu la aluminium thovu ndi lopepuka kwambiri, kuyika kwa denga kumatha kupangidwa mwakufuna gluing, kupachika kwa I-beam, kuyamwa kwa maginito, kosavuta kwambiri.

Chithovu cha Nickel chikukopa chidwi kwambiri pamagulu ophatikizika, makamaka zinthu zatsopano zopangidwa ndi BEIHAI Composites. Nkhani yapaderayi ili ndi ntchito zambiri komanso zopindulitsa, zomwe zimapangitsa kuti zikhale zofunikira kwambiri m'mafakitale osiyanasiyana.

M'zaka za zana la 21, ndi zida zankhondo zochulukirachulukira, zolakwa ndi chitetezo ziyenera kudalira zida zankhondo zasayansi, zamphamvu komanso zopepuka (zisoti, malaya amkati, mapewa, zophimba kumaso) kuti zidziletse kusandutsidwa chakudya cha mizinga.
Ndi zida zotani zomwe zili zotetezeka kwambiri popeza luso lankhondo lapita patsogolo? Kupambana kwaposachedwa kwambiri ndi malaya amkati osalowa zipolopolo opangidwa ndi thovu lachitsulo lophatikizika lomwe limatha kusweka chipolopolo chowuluka mosangalala.
Sichitsulo chilichonse, koma chopangidwa ndi kusungunula aluminiyumu mozungulira mpira wachitsulo wopanda kanthu. Chithovu chachitsulo chophatikizika ndi chopepuka kuposa 70% kuposa chitsulo chokhazikika - ndipo chimatenga mphamvu zochulukirapo 80 kuposa chitsulo. Zida zankhondo zimapangidwa ndi chitsulo chophatikizika chachitsulo ndi boron carbide ceramic, pomwe mbale yakumbuyo ndi Kevlar.

Chithovu cha Aluminiyamu Monga mtundu watsopano wokongoletsera malo, Aluminiyamu Foam yawonetsa kukongola kwake kwapadera komanso chiyembekezo chogwiritsa ntchito kwambiri pantchito yokongoletsa mkati mwanyumba yayikulu.
