Ponena za chotchinga chomveka, aliyense ayenera kuchidziwa bwino.Monga mlonda wamsewu, imamangidwa pagwero la phokoso kapena mbali zonse za msewu.Phokosolo likatumizidwa ku chotchinga cha mawu, lidzagwedezeka ndipo lidzatenga gawo lina.Ndiye phokoso chotchinga makamaka zochokera phokoso mayamwidwe.Chani?Masiku ano, opanga zotchinga zomveka adzakuuzani za izo.
Wopanga zotchinga zomveka
1. Ubweya wagalasi
Ubweya wagalasi wa Centrifugal ndi mtundu wazinthu zotchinjiriza zomwe zidatuluka m'ma 1980.Ndi membala wa banja la fiber glass.Imagwiritsa ntchito ukadaulo wapamwamba kwambiri wapadziko lonse lapansi wowomba ma centrifugal kuti upangitse magalasi osungunuka ndikuwapopera ndi utomoni wa thermosetting.Zinthuzo zimachiritsidwa ndi kutentha.
Ubweya wagalasi umapangidwa makamaka ndi mchenga wa quartz, feldspar, sodium silicate, boric acid, ndi zina zambiri, zomwe zimapangidwa ndi thonje lagalasi losungunuka kwambiri.
Makhalidwe azogulitsa a thonje loyamwa magalasi: kulemera kopepuka, kokwanira kwa mayamwidwe apamwamba, magwiridwe antchito abwino oletsa moto komanso kukhazikika kwamankhwala kwabwino kwambiri, ndipo sikumatsimikizira chinyezi.
2. Aluminiyamu CHIKWANGWANI
Aluminiyamu fiber sound absorbing panel ndi mtundu wachitsulo wotulutsa mawu womwe umapangidwa ndi mbali ziwiri za aluminiyamu mesh net sandwiching ulusi wa aluminiyumu womveka ndi zojambulazo za aluminiyumu.Ili ndi ntchito yabwino kwambiri yoyamwitsa mawu, kulimba kwamphamvu kwambiri, zinthu zopepuka, mayendedwe osavuta komanso kukana kwanyengo.
Aluminiyamu CHIKWANGWANI ali ndi makhalidwe awa:
Zinthu zoonda kwambiri: Makulidwe a aluminiyumu yotulutsa mawu otulutsa mawu nthawi zambiri amakhala pakati pa 0.8-2mm, ndipo kachulukidwe ka bolodi ndi 1.4-3.2kg/m2.Zosavuta kunyamula chifukwa cha kukula kwake kochepa komanso kulemera kwake
1. The 35mm wandiweyani kuchepetsa phokoso koyenera ndi 0.7, ndi 1.8mm wandiweyani kuchepetsa phokoso coefficient ndi 0.9.
Zokongoletsa: The bolodi akhoza utoto mitundu yosiyanasiyana, mtundu ndi wokongola kwambiri, ndi kukongoletsa kwenikweni ndi mayamwidwe phokoso.
Kukonza kosavuta: Mbale ya aluminiyamu imatha kukonzedwa bwino kwambiri, yosavuta kubowola, kupindika ndi kudula.Ntchito yomangayo ikachitika, sipadzakhala fumbi la fiber lomwe limwaza ndikuwononga chilengedwe komanso kukhudza thanzi la ogwira ntchito.
2, aluminiyamu ya thovu
Chithovu cha aluminium chimapangidwa ndi aluminiyamu yoyera kapena kuwonjezeredwa ndi zowonjezera mu aloyi ya aluminiyamu.Imakhala ndi thovu ndipo imakhala ndi zitsulo komanso kuchita thovu.
Chithovu cha aluminiyamu chimakhala ndi ntchito yabwino kwambiri yotulutsa mawu, kuchuluka kwa mayamwidwe a phokoso sikupitirira 0.64, ndipo phokoso lochepetsera phokoso liri pakati pa NRCO.75, yomwe ndi yabwino kwambiri phokoso la magalimoto makamaka potengera mafupipafupi ndi otsika. , ndipo ndi wapamwamba kuposa mitundu ina ya zipangizo zokomera mawu.Pamwamba pa aluminiyumu yokhala ndi thovu imatha kudziyeretsa pambuyo pa mvula, popanda kusokoneza magwiridwe antchito.
