Eminyakeni yamuva, isidingo sezakhiwo ezisimeme nezisebenza kahle siye sanikeza izinto ezithile ukugqama okukhethekile emhlabeni wokwakha. Omunye wabo, the idwala uvolo, ibonakale iyinketho evelele yayo izakhiwo ze-insulating, ukuziphatha kwayo lapho ibhekene nomlilo kanye nezinzuzo zayo zemvelo.
Lokhu kwaziswa, etholakala ezinqubweni zemvelo futhi esimeme, hhayi kuphela ngcono Ukunethezeka okushisayo y i-acoustic yezikhala, kodwa futhi imele inzuzo enkulu ukunciphisa ukusetshenziswa kwamandla kanye nesisi esingcolisa umoya. Ngezansi, sibheka ngokujulile ukuthi iyini, ikhiqizwa kanjani, izici zayo zobuchwepheshe, nazo zonke izinzuzo ezinikezayo kumaphrojekthi wokwakha angangeni emvelweni.
Iyini i-rock wool futhi yenziwa kanjani?
Uboya bedwala a insulating impahla yemvelaphi amaminerali etholakala ekuhlanganisweni kwe amatshe entaba-mlilo njenge-basalt futhi, ezimweni eziningi, ngokuhlanganiswa kwe imfucuza yezimboni egaywe kabusha, njenge-slag yensimbi. Le nqubo yokukhiqiza igqugquzelwa yindlela, ngokwemvelo, umoya kanye nodaka lwentaba-mlilo okungakhiqiza ngayo ukwakheka koboya kulandela ukuqhuma kwentaba-mlilo.
Embonini, lokhu kuhlanganiswa kwenziwa ezithandweni ezifinyelela amazinga okushisa afinyelela phezulu I-1500 ºC, lapho izinto ziphenduka zibe udaka oluwuketshezi. Umshini ojikelezayo ube ususetshenziswa ukuze kuguqulwe udaka oluncibilikisiwe lube imicu ecolekile, efana nefiber, ehlanganiswa ndawonye ukuze yakhe isakhiwo esinezimbotshana.
Ukwenza ngcono ukuhlangana kwayo futhi uyinikeze izici ezengeziwe, a isixazululo esibophezelayo elungisa imicu ndawonye, kanye namafutha baxosha amanzi. Khona-ke uvolo luyacindezelwa, lomiswe, lupholiswe, futhi ekugcineni lusikwe lube ubukhulu obufunekayo ngaphambi kokuba lupakishwe ukuze lusakazwe.
Izici zobuchwepheshe zoboya bedwala
Lokhu kwaziswa akugcini nje ngokugqama ngenxa yayo imvelo yemvelo, kodwa futhi yayo ukusebenza kobuchwepheshe okuphezulu kakhulu. Ngezansi, sibuyekeza ezinye zezakhiwo zayo ezihambisana kakhulu:
- I-Thermal conductivity: Inamanani phakathi kuka-0.033 no-0.042 W/m·K, okuyenza ibe isivikelo esihle kakhulu.
- Ukumuncwa kwe-Acoustic: Ngama-coefficients afika ku-1.00, iqinisekisa ukufakwa komsindo ophezulu.
- Ukumelana nomlilo: kuhlukaniswa njenge I-Euroclass A1, ayishi futhi ingamelana nezinga lokushisa elingaphezu kuka-1000 ºC.
- Ukuzinza kwe-Dimensional: igcina isimo sayo ngokuhlukahluka komswakama noma izinga lokushisa.
- Manzi: imunca ngaphansi kuka-1 kg/m², igwema izinkinga ezifana nokwakheka kwesikhunta.
- Ukumelana nomhwamuko wamanzi: ivumela isitimu ukuba sidlule, sisize izindonga ukuba ziphefumule.
Ukusetshenziswa kanye nezicelo emkhakheni wezokwakha
Ngibonga wakho nokuguquguquka, uboya bedwala bungasetshenziswa ezindaweni eziningi ngaphakathi kwesakhiwo:
- Ama-facade anomoya y izindonga zangaphandle ukuthuthukisa ukusebenza kahle kwamandla.
- Ukuhlukaniswa kwangaphakathi, usilingi kanye naphansi ukuze kufakwe ukushisa okushisayo nokuzwakalayo.
- Izindonga zomlilo kanye nezindawo ezidinga ukumelana nomlilo.
- Ukulungiswa kwekhaya, ukuvuselelwa kwamandla noma ukufakwa okuthuthukisiwe kwezakhiwo ezindala.
Iphinde ibe nezicelo ezingaphandle kwendawo yokuhlala, njengase-in izindawo zokugcina izimpahla zezimboni, izikole, izibhedlela, amahhovisi futhi ngisho naku umkhakha wasolwandle.
Ukushisa okushisayo nokusebenza kahle kwamandla
Enye yezinzuzo ezinkulu ze-rock wool yikhono layo loku ukunciphisa ukushintshana kokushisa phakathi kwengaphandle nengaphakathi lesakhiwo. Ngokunciphisa i- ukulahlekelwa okushisayo ebusika kanye nenzuzo ehlobo, indawo yasendlini enethezekile ifinyelelwa ngaphandle kwesidingo sokusebenzisa kakhulu ukushisa noma isimo somoya.
Lokhu kuholela kufayela le- ukusetshenziswa kwamandla okuphansi futhi, ngakho-ke, ukwehla okukhulu kwezindleko zesimo somoya. Lokhu kusebenza kahle kwenza i-rock wool ibe yinsika eyisisekelo yanoma yiliphi isu lokusimama ekwakhiweni, elifana nalokho okubonakala ku- izakhiwo ze-eco namandla avuselelekayo abasebenzisa le mikhuba.
Ukufakwa komsindo: ukunethezeka ngaphandle komsindo
Esinye isici lapho uboya be-rock budlula khona yikhono labo loku amunce amaza omsindo, ukuvimbela umsindo ukuthi ungangeni ezindongeni noma ophahleni. Ngama-coefficients wokumunca afika kokungu-1.00, isebenza ngempumelelo ngokumelene nomsindo osemoyeni (njengamazwi noma ithrafikhi) nomsindo womthelela (izinyathelo noma amagalelo).
Le insulation iwusizo ikakhulukazi ku izindlu zemindeni eminingi, amahhovisi avulekile, amahhotela, izitudiyo zokuqopha o Izikhungo zemfundo, lapho ukunethezeka kwe-acoustic kuyisidingo esikhulayo. Ukuqaliswa kwezixazululo ezifana ne-rock wool kunomthelela a umklamo wangaphakathi esimeme.
Ukumelana nomlilo: ukuphepha okuqinisekisiwe
I-Rock wool, eyakhiwe ngamaminerali, i ezingashi futhi ayikhiphi amagesi anobuthi lapho ishile. Lokhu kwenza kube umlingani omkhulu emikhakheni lapho i- ukuvimbela umlilo kubalulekile.
Isetshenziswa ku ama-firewall, usilingi, izitezi eziphakanyisiwe noma izimvilophu zobuchwepheshe ezakhiweni zomphakathi nezizimele. Isilinganiso sayo somlilo esingu-A1 siqinisekisa ukuthi, uma kuba nomlilo, siyasiza ukubambezela ukubhebhetheka kwamalangabi futhi sinikeze isikhathi esengeziwe sokuphuma. Lokhu kubaluleke kakhulu kumongo we izindlu ezisimeme, ezibeka kuqala kokubili ukusebenza nokuvikeleka.
Ukumelana nomswakama: impilo nokuqina
Esinye isici esiyinhloko soboya be-rock yisona ukumelana kwamanzi nomswakama. Ngokungafani namanye ama-insulators, ayiwagcini amanzi ngakho-ke ayikhuthazi ukukhula kwesikhunta noma amagciwane, igcina izakhiwo zayo zokuvikela ziqinile ngokuhamba kwesikhathi.
Lokhu kuyenza ilungele ukufakwa izindawo ezinomswakama njengezindlu zangaphansi, izindlu zangasese, amakhishi noma izakhiwo ezitholakala ezindaweni ezisogwini ezinomswakama ophezulu. Ngokufanayo nezinye izixazululo, ukuqina kwayo okuphezulu kunomthelela ekusimameni emkhakheni wezokwakha.
Ukusimama kanye nezinzuzo zemvelo
I-Rock wool inokugxila ngokusobala kwemvelo. Akwenziwa nje kuphela izinto zokusetshenziswa eziningi ezifana ne-basalt, kodwa futhi ingagaywa kabusha ngokuphelele ekupheleni kokusebenza kwayo.
Ngaphezu kwalokho, ukukhiqizwa kwayo kukhiqiza ukukhishwa kwe-CO2 okuphansi uma kuqhathaniswa nezinye izinto zokuvikela i-insulating, futhi ukuqina kwayo kunciphisa isidingo sokushintshwa noma ukulungiswa njalo, okunomthelela emnothweni oyindilinga. Ngalo mqondo, kubalulekile ukucabangela ezinye izindlela ezifana nokusetshenziswa kwe biomethane ukuthuthukisa ukusimama.
Ukufakwa nokugcinwa
Enye yamaphuzu aqinile we-rock wool ukuthi kunjalo kulula ukufaka. Ingasikwa ngamathuluzi alula futhi ihambisane nanoma yiluphi uhlobo lwendawo noma ifomethi, ngaphandle kwesidingo semishini esindayo noma izinqubo eziyinkimbinkimbi.
Mayelana nesondlo, kungokoqobo engekho. Ngenxa yokuqina kwayo kwe-dimensional, ukumelana nama-ejenti angaphandle, nokuqina, igcina izakhiwo zayo zokuvikela amashumi eminyaka.
Kukho konke lokhu kuhlaziya, sibonile ukuthi uboya bedwala bubekwe kanjani njengenye yezinto eziphelele emkhakheni wokwakha okusimeme. Izakhiwo zayo zobuchwepheshe, kuhlangene nomthelela wayo ophansi kwezemvelo, ziyenza ibe yingxenye ebalulekile yokuthuthukisa ukusebenza kahle kwamandla, ukwandisa ukuphepha, nokunikeza induduzo enkulu kuzo zonke izinhlobo zezakhiwo.
Ngaphezu kwalokho, ukusebenzisana kwayo ngezindlela ezihlukahlukene ekufakeni nasekumelaneni kwayo nomlilo, umsindo, umswakama, kanye nokuhamba kwesikhathi kuyenza ibe ukutshalwa kwezimali okuhlakaniphile nokuphephile kumaphrojekthi azibophezele emvelweni nasenhlalakahleni yabantu.
