Mhlawumbi ukugquma kukaloliwe omdala obalekayo kumboniso bhanyabhanya kunokuvuselela iinkumbulo zethu zobuntwana ngokulula, ngokungathi sibalisa ibali lexesha elidlulileyo.
Kodwa xa olu hlobo lwesandi lungekho kwiimuvi, kodwa luhlala luvela kwikhaya lethu, mhlawumbi le "nkumbulo yobuntwana" ijika ibe ziingxaki ezingapheliyo ngephanyazo. Esi sandi singemnandanga yingxolo.
Ingxolo ayiphazamisi nje amaphupha abantu kuphela, kodwa okona kubalulekileyo, imeko-bume yengxolo yexesha elide inokubangela umonakalo ongenakulungiseka kwi-physiology kunye nengqondo yabantu, kwaye yenye yezona zinto zibalulekileyo zongcoliseko kwimekobume yanamhlanje.
Ukunciphisa ingxolo kunye nokugqunywa kwesandi kuye kwaba yimfuno engxamisekileyo engqongqo yabantu.
Ngokuqhelekileyo, izinto ezichaphazela inqanaba lengxolo ziquka ubukhulu becala umthamo womthombo wesandi kunye nomgama phakathi komsindo kunye nomthombo wesandi.
Kwimeko yokuba umthamo, i-audio frequency kunye nomgama phakathi komthombo wesandi kunye nomntu akatshintshi lula, ngokomeleza umqobo wesandi somzimba - ukusebenza kwesandi sokugquma kweengcango kunye neefestile, ukuhanjiswa kwesandi kuvaliwe kangangoko kunokwenzeka, ngaloo ndlela. ukwenza ulonwabo kwaye ukhululekile okusingqongileyo.
Ingxolo ayikhululeki ngokwasemzimbeni okanye ngokwasengqondweni, ayithandeki, ayikhululeki, ingafunwa, okanye izandi ezicaphukisayo, ezingamkelekanga kwabo bayivayo, ezichaphazela incoko okanye ukucinga kwabantu, umsebenzi, ukufunda, kunye nokuphumla isandi se.
Uluhlu lwezandi zokuva kwindlebe yomntu malunga ne-20Hz ~ 20kHz, kwaye uluhlu oluphakathi kwe-2kHz kunye ne-5kHz yeyona ndawo inovakalelo kwindlebe yomntu. Izandi ezisezantsi kakhulu neziphezulu kakhulu zinokubangela ukungakhululeki.
Olona luhlu lwevolumu lukhululekile ngu-0-40dB. Ke ngoko, ukulawula indawo yethu yokuhlala kunye nokusebenza kwe-acoustic kule ndawo kunokuphucula intuthuzelo ngokuthe ngqo nangoqoqosho.
Ingxolo ye-low-frequency ibhekisela kwingxolo ene-20 ~ 500Hz, i-frequency ye-500Hz ~ 2kHz yi-frequency ephakathi, kwaye i-frequency ephezulu yi-2kHz ~ 20kHz.
Kubomi bemihla ngemihla, i-air-conditioning compressors, oololiwe, iinqwelomoya, iinjini zemoto (ingakumbi kufutshane neendlela kunye ne-viaducts), iinqanawa, iilifti, oomatshini bokuhlamba, iifriji, njl. , izixhobo zomculo, i-square dance, inja ekhonkothayo, usasazo lwesikolo, iintetho, njl. njl. ubukhulu becala ziingxolo eziphuma phezulu.
Ingxolo ye-low-frequency inomgama omde wothumelo, amandla okungena anamandla, kwaye ayitshintshi kakhulu ngomgama, owona yingozi kakhulu kwi-physiology yabantu.
Ingxolo ye-high-frequency inokungena okungahambi kakuhle, kwaye iya kuncitshiswa kakhulu njengoko umgama wokusabalalisa ukhula okanye udibana nemiqobo (umzekelo, ngokunyuka kweemitha ezili-10 kumgama wokusasazwa komsindo ophezulu, ingxolo iya kuthotywa yi-6dB).
Umthamo ngowona unomdla wokuziva. Umthamo ulinganiswa ngee-decibels (dB), kwaye umthamo we-ambient ngaphantsi kwe-40dB yeyona ndawo ikhululekile.
Kwaye umthamo ongaphezulu kwe-60dB, abantu banokuziva bengonwabanga.
Ukuba umthamo udlula i-120dB, kuthatha umzuzu omnye kuphela ukubangela ukungeva okwethutyana kwindlebe yomntu.
Ukongeza, umgama phakathi komthombo wesandi kunye nomntu kwakhona uchaphazela indlela umntu ayibona ngayo ingxolo. Okukhona umgama uqhubeka, kokukhona uphantsi umthamo.
Nangona kunjalo, kwingxolo ye-low-frequency, impembelelo yomgama ekunciphiseni ingxolo ayibonakali.
Xa kungenakwenzeka ukwenza utshintsho oluninzi kwindawo enenjongo, kunokuba lukhetho lobulumko ukutshintshela kumnyango okumgangatho ophezulu kunye nefestile, kwaye uzinike ikhaya elinoxolo nelihle.
Iseti elungileyo yeengcango kunye neefestile inokunciphisa ingxolo yangaphandle ngaphezulu kwe-30dB. Ngolungelelwaniso lwendibaniselwano yobuchwephesha, ingxolo inokuncipha ngakumbi.
Iglasi iyona nxalenye ibaluleke kakhulu echaphazela ukugquma kwesandi kwiingcango kunye neefestile. Kwiintlobo ezahlukeneyo zengxolo, ukuqwalasela iglasi eyahlukileyo lolona khetho lobuchule kunye noqoqosho.
Ingxolo ephezulu frequency - insulating glass
Iglasi ye-insulating yindibaniselwano yeziqwenga ezi-2 okanye ngaphezulu zeglasi. Irhasi ekumaleko ombindi womngxunya inokufunxa amandla okungcangcazela kwesandi esiphakathi kunye nesiphezulu, ngaloo ndlela inciphisa ukuqina kwesandi.Isiphumo sokugquma kwesandi seglasi yokugquma inxulumene nobukhulu beglasi, irhasi yomaleko ongenanto kunye nenani kunye nobukhulu be-spacer layer.
Kwiimeko ezininzi, iglasi ye-insulating inesiphumo esihle kakhulu sokuthintela kwingxolo ephakathi nendawo ephezulu. Kwaye ngalo lonke ixesha ubukhulu beglasi buphindwe kabini, ingxolo inokuncitshiswa ngo-4.5 ~ 6dB.
Ngoko ke, ubukhulu beglasi ubukhulu beglasi, isandi somelele.
Sinokuyiphucula impembelelo yokugquma kwesandi kwiingcango kunye neefestile ngokunyusa ubukhulu beglasi yokugquma, ukuzalisa igesi engasebenziyo, kunye nokwandisa ubukhulu bomaleko ongenanto.
Isandi esiphantsi-insulatingiglasi elaminethiweyo
Ngaphantsi kobukhulu obufanayo, iglasi elaminethiweyo inefuthe elibonakalayo ekuthinteleni amaza aphakathi kunye namaza aphantsi omsindo, angcono kuneglasi yokugquma.
Ifilimu embindini weglasi elaminethiweyo ilingana nomgangatho omanzi, kwaye umaleko wokuncamathelisa we-PVB usetyenziselwa ukufunxa amaza omsindo aphakathi kunye naphantsi kwaye ucinezele ukungcangcazela kweglasi, ukuze kuphunyezwe isiphumo sokugquma isandi.
Kuyafaneleka ukuba uqaphele ukuba ukusebenza kwe-sound insulation ye-interlayer kunokuchaphazeleka kubushushu.
Ebusika obubandayo, i-interlayer iya kulahlekelwa enye ye-elasticity ngenxa yokushisa okuphantsi kunye nokunciphisa impembelelo yomsindo. Iglasi ye-laminated enomgobo, edibanisa iingenelo zombini zeglasi engenanto kunye neglasi elayitiweyo, inokuchazwa njengeglasi "ejikelezileyo" engenasandi.
Ulwakhiwo olutywiniweyo-uBanga lokuSebenza kwiBanga lokuNgena lizwi
Ukongeza kokuthembela kwiglasi, ukugquma kwesandi esilungileyo kukwanxulumene ngokusondeleyo nesakhiwo sokutywina.
I-MEDO isebenzisa iintlobo ezahlukeneyo ze-EPDM ze-automotive-grade-grade-sealing materials ezifana ne-soft and hard co-extrusion, i-foam epheleleyo, njl., ezinokuqina okugqwesileyo kwaye inokunciphisa ngempumelelo ukuqaliswa kwesandi. Uyilo lwesakhiwo sokutywinwa kweendlela ezininzi zombhobho, kunye neglasi, ziyancedisana ukwakha umqobo wengxolo.
indlela evulekileyo
Nangona kukho iindlela ezahlukeneyo zokuvula iingcango kunye neefestile zenkqubo, idatha yovavanyo ibonisa ukuba indlela yokuvula i-casement yokuvula ingcono kunokutyibilika ngokwemiqathango yokumelana noxinzelelo lomoya, ukutywinwa kunye nokugquma isandi.
Ngesiseko seemfuno ezibanzi, ukuba ufuna ukugquma isandi esingcono, iingcango zecasement kunye neefestile zikhethwa.
Ukongeza, ijika iifestilekunye neefestile ze-awning zinokuthathwa njengeendlela ezikhethekileyo zokusebenzisa iingcango zecasement kunye neefestile, ezineenzuzo zefestile zecasiment kwaye zineenzuzo zazo ezikhethekileyo, ezifana neefestile ezijikelezayo ezikhuselekileyo kwaye zithambile ngakumbi ekungeneni komoya.
I-MEDO, ethatha ingcali yesisombululo senkqubo njengoxanduva lwayo, iqokelele phantse iminyaka engama-30 yokuqokelela itekhnoloji, ixhomekeke kwisityebi kunye nesigxina sesiseko semveliso yemveliso, iguqulela indawo yesicelo kunye neemfuno zabathengi kulwimi loyilo, kwaye isebenzisa ubuchwephesha kunye nobungqongqo. Isimo sengqondo sezenzululwazi sokuma kweyona basebenzisi bangcono kakhulu, amava ombono wokubonelela ngesisombululo esisiso kwiprojekthi nganye kunye nokucinga okucwangcisiweyo kunye noyilo oluphambili.
