Zvigadzirwa zvegirazi zvemvere dzemasangweji madziro zvakakamurwa kuva marudzi maviri: girazi mvere dzakanzwa uye girazi mvere bhodhi.Pamusoro peinonzwa kana bhodhi rinogona kuputirwa neglue dema kana kunamatira nerunyoro rwedema (mabviro: China Insulation Network) girazi fiber inonzwikwa kusimbisa.Inokodzera kushandiswa kwekutengeserana., Thermal insulation yemadziro maviri muindasitiri uye zvivakwa zveveruzhinji.

Zvigadzirwa zvegirazi zvemvere dzemasangweji madziro zvinogona kukupa zvinotevera zvikomborero: Kudzivirira condensation, kuderedza uremu hwemadziro, kuwedzera nzvimbo yekushandisa, kuchengetedza simba, kuwedzera kunyaradza, kuvharira inzwi, uye kudzivirira moto.

Centrifugal girazi shinda ine yakanaka inonzwika kunyudza kuita kwepakati-kusvika-yakakwira-frequency ruzha.Zvinhu zvikuru zvinokanganisa kuita kwekurira kweiyo centrifugal girazi mvere ndiko ukobvu, density uye kuramba kuyerera kwemhepo.Density huremu hwezvinhu pa cubic meter.Mhepo kuyerera kupikisa chiyero chekumanikidzwa kwemhepo uye kumhanya kwemhepo pamativi ese echinhu pahukobvu hweyuniti.Kuramba kuyerera kwemhepo ndicho chinhu chakanyanya kukosha chinokanganisa kurira kwekuita kwe centrifugal girazi remvere.Kana kuyerera kwekudzivirira kuri kudiki, zvinoreva kuti zvinhu zvacho zviri zvishoma uye kudengenyeka kwemhepo kuri nyore kupfuura, uye kuita kwekunzwa kwekurira kunoderedzwa;kana kuyerera kwekudzivirira kwakakura zvakanyanya, zvinoreva kuti zvinhu zvakanyanyisa, kudengenyeka kwemhepo kunonetsa kufambisa, uye kuita kwekuita kwekurira kwakaderedzwa zvakare.

Kune centrifugal girazi mvere, iyo inzwi inonwisa kuita ine yakanyanya kuyerera kuramba.Muinjiniya chaidzo, zvakaoma kuyera kuyerera kwemhepo, asi inogona kufungidzirwa uye kudzorwa nekukora uye kuwanda kwehuwandu.

1. Nekuwedzera kwehupamhi, ruzha rwekunyura coefficient yepakati uye yakaderera frequency inowedzera zvakanyanya, asi iyo yakakwirira frequency inochinja zvishoma (yakakwira frequency absorption inogara yakakura).
2. Kana ukobvu husina kuchinjika, kuwanda kwehuwandu hunowedzera, uye ruzha rwekupinza coefficient yepakati-yakaderera frequency inowedzerawo;asi kana kuwanda kwehuwandu hunowedzera kune imwe nhanho, zvinhu zvinova dense, kuyerera kwekupokana kwakakura kupfuura iyo yakanyanya kuyerera kuyerera, uye iyo inzwi rekutora coefficient inoderera panzvimbo.Kune centrifugal girazi wool ine hukuru density ye16Kg/m3 uye ukobvu hunodarika 5cm, yakaderera frequency 125Hz ingangoita 0.2, uye yepakati uye yakakwirira frequency (> 500Hz) inonzwika coefficient iri pedyo ne1.
3. Kana ukobvu huchiramba huchiwedzera kubva pa5cm, iyo yakaderera-frequency yekunyudza inonzwika coefficient zvishoma nezvishoma inowedzera.Kana ukobvu hwakakura kupfuura 1m, iyo yakaderera-frequency 125Hz inopfenyura coefficient ichave zvakare pedyo ne 1. Kana ukobvu huripo uye kuwanda kwehuwandu huchiwedzera, iyo yakaderera-frequency inotorwa inonzwika coefficient ye centrifugal girazi wool icharamba ichiwedzera.Kana iyo yakawanda density iri padyo ne110kg/m3, kuita kwekurira kwenzwi kunosvika pakukosha kwayo, iyo iri pedyo ne0.6-0.7 pahupamhi hwe50mm uye frequency ye125Hz.Kana kuwanda kwehuwandu hunopfuura 120kg/m3, kuita kwekurira kweruzha kunodzikira nekuti zvinhu zvinova zvakanyanyisa, uye iyo yepakati-uye yakakwirira-frequency yekunyudza inzwi inokanganiswa zvakanyanya.Kana iyo yakawanda density ichipfuura 300kg/m3, kuita kwekurira kwekurira kunoderera zvakanyanya.

Ukobvu hwegirazi-inotora girazi shinda inowanzoshandiswa mukuvaka acoustics ndeye 2.5cm, 5cm, 10cm, uye huwandu hwayo huzhinji ndeye 16, 24, 32, 48, 80, 96, 112kg/m3.Kazhinji shandisa 5cm gobvu, 12-48kg/m3 centrifugal girazi wool.
