Imikhiqizo yoboya bengilazi yezindonga zesangweji ihlukaniswe yaba izinhlobo ezimbili: uboya bengilazi bezwa kanye nebhodi loboya bengilazi.Ingaphezulu lomzwelo noma ibhodi lingagcotshwa ngeglue elimnyama noma linamathele ngongqimba olumnyama (umthombo: I-China Insulation Network) i-fiber yengilazi ezwakele ukuze kuqiniswe.Ilungele ukusetshenziswa kwezohwebo., Ukushisa okushisayo kwezindonga eziphindwe kabili ezakhiweni zezimboni nezomphakathi.

Imikhiqizo yoboya bengilazi yezindonga zamasemishi ingakunikeza izinzuzo ezilandelayo: Vimbela ukuminyana, ukunciphisa isisindo sodonga, ukwandisa indawo okusetshenziswa kuyo, ukonga amandla, ukwandisa ukunethezeka, ukuvala umsindo, nokuvimbela umlilo.

Uboya bengilazi be-Centrifugal bunokusebenza okuhle kokumunca umsindo komsindo we-mid-to-high-frequency.Izici eziyinhloko ezithinta ukusebenza kokumuncwa komsindo koboya bengilazi obuyicentrifugal ukushuba, ukuminyana kanye nokumelana nokugeleza komoya.Ukuminyana yisisindo sempahla nge-cubic meter ngayinye.Ukumelana nokugeleza komoya isilinganiso somfutho womoya kanye nesivinini somoya ezinhlangothini zombili zento ngayinye ubukhulu beyunithi.Ukumelana nokugeleza komoya kuyisici esibaluleke kakhulu esithinta ukusebenza kokumuncwa komsindo koboya bengilazi obuyicentrifugal.Uma ukumelana nokugeleza kukuncane kakhulu, kusho ukuthi izinto ezibonakalayo ziyingcosana futhi ukudlidliza komoya kulula ukudlula, futhi ukusebenza kokumuncwa komsindo kuyancipha;uma ukumelana nokugeleza kukhulu kakhulu, kusho ukuthi impahla iminyene, ukudlidliza komoya kunzima ukudlulisa, nokusebenza kokumuncwa komsindo nakho kuyancipha.

Ngoboya bengilazi obuyi-centrifugal, ukusebenza kokumuncwa komsindo kunokumelana nokugeleza okungcono kakhulu.Kubunjiniyela bangempela, kunzima ukukala ukumelana nokugeleza komoya, kodwa kungalinganiselwa futhi kulawulwe ukushuba nokuminyana kwenqwaba.

1. Ngokukhula kokuqina, i-coefficient yokumunca umsindo yemvamisa ephakathi nendawo nephansi ikhula kakhulu, kepha imvamisa ephezulu ishintsha kancane (ukumunca imvamisa ephezulu kuhlala kukhudlwana).
2. Uma ukushuba kungaguquki, ukuminyana kwenqwaba kuyanda, futhi i-coefficient yokumunca umsindo yefrikhwensi ephakathi nendawo ephansi nayo iyanda;kodwa lapho ukuminyana kwenqwaba kukhuphukela ezingeni elithile, impahla iba minyene, ukumelana nokugeleza kukhulu kunokumelana nokugeleza okufanele, futhi i-coefficient yokumunca umsindo iyehla esikhundleni.Ngoboya bengilazi obuyi-centrifugal obunobuningi obungu-16Kg/m3 nogqinsi olungaphezu kuka-5cm, imvamisa ephansi engu-125Hz icishe ibe ngu-0.2, futhi i-coefficient yokumunca yomsindo emaphakathi nendawo ephezulu (>500Hz) isondele ku-1.
3. Lapho ukujiya kuqhubeka nokukhula kusuka ku-5cm, i-coefficient yokumunca umsindo wemvamisa ephansi kancane kancane iyanda.Uma ukujiya kungaphezu kuka-1m, i-coefficient yokumunca yomsindo we-low-frequency engu-125Hz izophinde isondele ku-1. Uma ukujiya kushintshana futhi ukuminyana kwenqwaba kuyanda, i-coefficient yokumunca umsindo we-low-frequency ye-centrifugal glasswool izoqhubeka nokukhula.Uma ukuminyana kwenqwaba kusondele ku-110kg/m3, ukusebenza kokumuncwa komsindo kufinyelela inani lakhona eliphezulu, eliseduze no-0.6-0.7 ekugqimeni kuka-50mm kanye nemvamisa engu-125Hz.Uma ukuminyana kwenqwaba kudlula u-120kg/m3, ukusebenza kokumuncwa komsindo kuyehla ngenxa yokuthi okokusebenza kuba minyene, futhi nokusebenza kokumuncwa komsindo we-mid-frequency ephezulu kuyathinteka kakhulu.Uma ukuminyana kwenqwaba kudlula u-300kg/m3, ukusebenza kokumuncwa komsindo kuncipha kakhulu.

Ubukhulu boboya bengilazi obumunca umsindo obuvame ukusetshenziswa ku-architectural acoustics bungu-2.5cm, 5cm, 10cm, futhi ubuningi babo bungu-16, 24, 32, 48, 80, 96, 112kg/m3.Ngokuvamile sebenzisa 5cm ukujiya, 12-48kg/m3 centrifugal glass wool.
