Ukuchaza Kwemithambo Nokufunda Umkhondo: Yini Okwenza Isinhlangano Sokugcina Isithunzi Sesibhakabhaka Sibe Yilokho Ekhubazekayo

Isibhakabhaka Esisheshile, i-MDF, Nezinkulungwane Zokugcina Isithunzi: Ukuhlaziya Kwezirating zokaSTC Kwezinkhulu, Izinqambu, Nokugcina Isithunzi

Indlela okubukwene kuyo indlu kusuka ngaphakathi kuyathuthukisa kakhulu ukuthi yisiphi isikhundla sokugcina umbono, okubhalwa ngokuthi STC rating. Kunezinto ezintathu eziphambili ekhona lapha: ubukhulu, ukugcina, nokuhlanganiswa. Izinto eziningi ziyasebenza kahle kuvimba umbono ngoba azihlabele kahle uma umbono uvala kubo kusuka ngaphandle. Lokho kukuthi izindlu ezenziwe ngamathambo amaningi njenge-‘solid hardwood’ noma MDF zisebenza kahle kunezinye ezincane. Iindlela zezindlu zezinhlangothi ze-MDF zingafumana i-STC rating engaphezulu kwe-40, okuyenza kuzo kubalulekile kuvimba izimbono zezinsuku zonke. Lezi zinhlangano zizithatha ubukhulu obukhulu kubukhulu bakho bazo ngaphandle kokuthi zibheke izimbono zezinkumbu ezingavimbi kahle ezikwenziwe ngamathambo amancane noma ezisemthandazweni yabo ngaphakathi.

Izinto ezihlanganisiwe eziyinhloko ziqhubekisela phambili izinto ngokusebenzisa indlela yazo enezingqimba, ngokuvamile zihlanganisa insimbi noma indawo ye-gypsum nalezo zinhlanganisela ezikhethekile zokunciphisa ezinekhwalithi ye-viscous elastic. Okwenzeka lapha kuyathakazelisa ngempela ukuthi lezi zinto ziguqula ukudlidliza kube amandla okushisa esikhundleni sokuzivumela zidlule, okwenza umehluko omkhulu uma kuziwa ekunciphiseni umsindo kumaza aphakathi. Uma sibheka indlela asebenza ngayo uma eqhathaniswa ne-standard single material cores, imiklamo esezingeni eliphakeme ecindezelwe ngokuvamile inikeza cishe amaphuzu angu-6 kuya kwangu-10 engeziwe e-STC. Lokho kubalulekile ezindaweni lapho abantu kudingeka bezwe omunye nomunye ngokucacile phakathi nezingxoxo noma bajabulele umculo ngaphandle kwemisindo engafuneki yangemuva.

Kungani Ukwakhiwa Kwezingqimba Ezinobukhulu, Ezinkulu, Nezinciphayo Kubusa Ekuhlukaniseni Okuphansi

Umsindo ongaphansi kuka-125 Hz ovela ezintweni ezinjengezinhlelo zokushisa, ama-elevator asebenza, noma ngisho nalezo zikhulumi ezinkulu zama-bass emagumbini omculo udala izinkinga ezinkulu zeminyango evimba umsindo. Inkinga iwukuba nalezo zimpondo ezinde eziqhubeka zidlula ezintweni esikhundleni sokuvinjwa.
