Indlela Imfundo Yokuvikela Kwezinyawo Iyahlukena Phakathi Kwe-Acrylic Ne-Polycarbonate
Umthetho Wemali, Ukuqina, Ne-Damping: Kungani Umphakathi Womthebe Uchaza Iziphumo Ze-STC
Ukuba sibheka izikithi zeSound Transmission Class (STC), singabona ukuthi kungani i-acrylic kanye ne-polycarbonate zihlenzela ngendlela eyahlukene njengemithuthi yesono ngokwemipawu yabo ephathelene. Ngokwesiqiniseko seLeyi yeMass, izinto ezinzima zombi zazinzima kakhulu ukuthi zivikile sona sona. Kodwa kukhona okuningi kunjalo kuphela. I-acrylic inemipawu engcono engayivikela sona, kodwa indlela yalo epholile yenza imiba emazingeni ethile. Ngokuthakatha kwezigaba phakathi kwe-500 kuye ku-2000 Hz, isono esigcwele kwi-acrylic singakhuphuka ngakude kuya ku-15 dB ngoba yizinkinga zokuxhasana. I-polycarbonate isebenza kahle kule ndawo ngoba inemipawu yokulahla. Okwakhiwe kwi-polycarbonate kungukuthi umphakathi walo wemolekiyu ungalungisa izivivinyo kumandla wokushisa, okusenza kube yisiphelo kwezigaba ezincane kusuka ku-500 Hz. Izivikelo zibonisa ukuthi ihlenzela kahle kakhulu kuma-acrylic ngaphezu kwe-30% kwezigaba ezincane ngokulingana kwebhodi. Ukuphola kuyindlela kumele kubalwe futhi kusizo sokugcina. I-acrylic inendlela yokuthembeka kakhulu ngokufakwa noma xa kuthathwa izigaba zokushisa ngokugcina, okokuthi kugcina kuyakwephula indlela yalo yokuvikela sona. I-polycarbonate isohlala inembile, isohlala inamandla okuvikela sona sona noma kuthathwa izidingo, yenza kube yisikrweleti esihle kakhulu kuzo zonke izifakelo lapho kudingeka ukusebenza kwesono kube yisiphelo.
I-Lab vs Izilingo Ezifanayo Ze-STC: Kungani Ukufakwa Kwasekhaya Kuyekela Ukwenzakala Kwesibopho Somthwalo Wengoma
Iziphumo zezivivinyo zeSTC kuzindiza zihlukanisa isimo esihle kakhulu kusebenza kwasebenzayo, zibonakala ngama-5 kuze kube nama-10 angaphezulu kunalokho okuhlukileyo emhlabeni. Lokhu kubekwa ngoba kunezindlela ezihlekile kumahlathi njengezigaba zomthombo, izikhwama zezilimi, izihlangothi ezingavumelekile kangako, njalo-njalo. Iziphumo zeacrylic kudinga ukufakwa okuphelele kungakhohlwa konke. Noma yiziphumo ezincane zokufaka kungahola ukuthi kuhluleke amanzi futhi kusuke isilinganiso seSTC ngama-20% uma kufakiwe embangalini. Kodwa-ke, ipolycarbonate inika into engahambelani noyilo, inkobe yakhe ivumela ukuthi isebenze ngisho xa izinhlangothi azidingi ukuba zide ngcono. Lokhu kusiza ekugcineni kwezilonda zomculo, ngakho ke kancane kabehlo isilinganiso seSTC esivelile kuzivivinyo kuzothinta kumsebenzi wasebhakheni, kuyathatha kancane kabehlo ama-90% weqiniso. Iziphatshwa ziyafakwa kakhulu emakhundleni apho ubude bwezulu bubuyekezwa. I-acrylic ihluka kakhulu ngenxa yokuguqulwa kwebhodi (ngaphaya kuka-7 x 10^-5 ngadekheride), ikhiye izindlela zokuhlola phansi kwezinsuku. Ipolycarbonate ayigxile ngaphezu (ngaphaya kuka-6.8 x 10^-5 ngadekheride) futhi isebenza ngokwesithunzi sasiphumo sokugcina. Lokhu kwenza ipolycarbonate ibe yisikhetho esihle kakhulu kumsebenzi lapho umculophumo kumele kuphileni, njengezihospitali ezingadinga ukugcinwa kwegazi labantu noma izistima zokurekhoda eprofeshinali apho ukunciphisa umbala kumele kube yisiphetho. Nakuba ziphawula izilinganiso ezifana, ipolycarbonate ithathe isikhathi eside kakhulu kumasebenzi akhona.

Izindlela Zokuphakama Nezinkinga Zokuphakama Kaphakathi Kwezinqamlezo zomniki we-Acrylic
Ubuchwepheshe buka-acrylic buza umbono omkhulu ngosiko: kuthanda ukuthutha izikhathi phakathi kwe-1000 ne-2000 Hz, lapho sesikhona indlela yethu yokuzwa kusika. Izinto ezinezindlela eziphazanyayo zisebenza ngendlela eyahlukene kuka-acrylic. Zithatha izikhathi ezihlukile ngenkathi zizange zizilunge. I-acrylic just izishumayela lezi zikhathi ngokuphambene, okungaba yinkinga yokuthatha izilinganiso ze-STC ngalokho-15 dB kulezi zikhathi ezikhathini ngokulinganisa kwezinye izikhathi. Lokhu kubangelwa kungaba yinkinga yokugcina ubumnandi kusengxenweni kumakhanda okanye emakhospitalini, noma uma izwi elincane zilungiswa kahle. Indlela i-acrylic iyasebenza khona iyaphila kakhulu kumzimba. Isebenza kahle kakhulu kumzimba lapho izikhathi eziphakathi azisingeki kakhulu ekuxhumanyweni.
Lapho i-Acrylic Esebenza: Izigaba zeNtabi Yezemphakathi Nezimathetho ze-STC 32—36
I-Acrylic isahluko esihle kakhulu ezinhlanganweni eziphazamisekayo kumzimba obuthakathi, okuphazamisekayo ubunzima, uhlelo lwemali, nokwakha kakhulu. Indawo yalo ebucayeni yizigaba zenjabulo zezemphakathi ezingalawa STC 32—36, ikakhulukazi lapho:
- Umthwalo wokungcola kwe-high-frequency uphazamiseka (isibonelo, umthwalo wokuhlaba kwemoto, izinhlangano ze-HVAC)
- Ukuxhumana ngokubona nokuthuthwa kwelanga elihleli (92%) kungaphezu kokuphatha ngokugcwele komsindo
- Imitholoko yemali ibekisa amandla ekusebenzisa izinto ezilambathwe noma eziningi izikhala
Idatha eqashelwa kumasebe enziwe ngokulungiswa ngamaphaneli avuthi kusho ukuthi amaphaneli akhrilikekhiwanga engu-6mm angakhubaza ubukhuni bezindlela ukusuka ku-65 dB usuka phansi kuya kwi-45 ne-50 dB emasethathamweni ngezindawo zomsebenzi ezingaphandle kwesahlalo. Lokhu kukhupha kunezidingo ezaneleyo kakhulu kumisebenzi yonke into yosuku ngaphandle kokunakekela abasebenzi bafute isiphotho kubekho kuphela phezu kwabo. I-akhrilikekhiwanga lingaphelela iglasi engcono xa kufikwa ekuphatheleni komthelelo, kodwa kukhona izimfuno. Lomthelelo awusebenze kahle kuzindawo okukhona kuzo izindaba eziningi zezifreqensi ezincane noma xa kudingeka ikhodi yesivumelwano sesono esiphezulu kunesi-40 ukugcina izibongo ziwuchithe. Kulokhu kube khona izinkinga eziphambene, izinkampani ziqeda ukuthi bazame izikhambi ze-polikhabhonethe ngendlela ethile ngaphandle kokulala kuzinhlelo zemfundo ye-akhrilikhi.
