Zvitatu zvakajairika acoustic zvinhu
Acoustic materials (zvikurukuru zvichireva zvinhu zvinobata inzwi) zvinosanganisira zvese zvehupenyu.MuUnited States, 1% chete yeacoustic materials inoshandiswa mundima yekurekodha mimhanzi, uye yakawanda inoshandiswa mukuvaka nekushongedza kwekugara, mahotera, maresitorendi, zvivako zvehofisi, nhandare, nezvimwewo. Pane zvinhu zvitatu zvakajairika zveacoustic mu China, asi mumwe nomumwe wavo ane matambudziko akakomba.
Yokutanga ibhegi rakapfava seponji.Ichi chinyorwa chine njodzi yakanyanya, uye chidzidzo chine ropa zvakanyanya yaive moto mubhawa muSanta Maria, Brazil muna Ndira gore rapfuura.Moto uyu wakauraya vanhu vanodarika mazana maviri nekukuvadza mazana.Vakakuvara vakazara muzvipatara zvose zvomunzvimbomo.Kubva pavhidhiyo mhenyu nemifananidzo, zvinogona kuonekwa kuti moto wakanga wakakura kwazvo, murazvo wakakwira nyaya dzakawanda, uye moto wakagara kwemaawa akawanda usati wadzima.Pepanhau reUnited States rinonzi “Los Angeles Times” rakati uyu ndiwo mwoto wakauraya zvikuru pasi rose mumakore gumi apfuura.
Maererano nekuferefeta, kuitira kugadzira mamiriro ekunze, bhendi repamba rakashandisa mafirework kuita mukirabhu yehusiku.Zvingave izvo twumoto zvinorova netsaona pamadziro efuro rinonzwika uye nekukurumidza kupararira padenga.Mukuru wemapurisa eSanta Maria, Marce, akataura kuti furo riri padenga rekirabhu yehusiku rinobvira moto uye rinongobvisa maungira uye harigone kushandiswa sechinhu chisina ruzha.“Iri ndiro bhegi rakapfava ratinogara tichitaura nezvaro iye zvino.Uzere nechipanje, kuti moto haugoni kudzora murazvo womoto, asi uchaubatsira.”
Pamusoro pekusachengeteka, kuita kwayo kunobata ruzha hakunawo kugadzikana, nekuti chipanje chinogadzirwa nezvinhu zvakabikwa zvinogara zvichikushwa, zvichipiswa, uye zvino kudzvanywa kuita chimiro.Munguva yese iyi, hapana chiyero chakafanana chetembiricha uye simba, saka kuwanda kwebatch yega yega yesponji kwakasiyana, uye ruzha rwekutorwa kweruzha rwakasiyanawo.
Rudzi rwechipiri ndeye polyester fiber inopfeza-inobata mapaneru.Nyaya iyi inogona kugadzirwa kuva mavara akasiyana-siyana, akanaka kwazvo uye ari nyore kuisa, asi zvakanakira izvi zvinogumira pane izvi, uye hazvina zvazvinoita pakunzwika.
Rudzi rwechitatu mapuranga emapuranga anotora-inzwi.Makambani mazhinji akashanya kunze kwenyika akaona kuti zvinhu zvemapuranga zvinotora ruzha zvinoshandiswa nevanhu zvakanaka uye zvinoshanda, saka vanodzoka kuzodzidza nekupfekedzawo huni pakushongedza.Kutaura zvazviri, rudzi urwu rwezvinhu zvinotora inzwi nemapuranga pamusoro, chinyorwa chiri kumashure, uye mhango inopinza inzwi kumusana ndiyo chaiyo inogadzirisa inzwi.Makambani emumba anowanzo kutevedzera muenzaniso wekuisa huni pamusoro, pasina gomba kumashure, uye zvechokwadi hapana kutorwa kwezwi.
