Roof ukwahlukanisa - Ukukhetha impahla

Ngaphambi kokuqala ukwahlukanisa of ophahleni, kudingeka kahle ukuhlola izinto ezihlukahlukene ezisetshenziswa njengoba ukwahlukanisa of ophahleni, ukwazi izinzuzo, nebubi, kanye emkhakheni wabo kwesicelo. Yenza isinqumo esifanele kuzokusiza izinto kulesi sihloko ngokuhlola okuyinto ongasakudingi ukungena ku-Internet izinjini nombuzo ngalokho vimbela ophahleni.

emakethe yanamuhla linikeza ithuba ukhetho olukhulu nangokuvikela izinto. Khona-ke abakhululiwe ezivamile: polystyrene kanye rock uvolo, igwebu ingilazi, ukhonkolo evundile futhi kube lukhuni ingilazi-fibre amapuleti. Ake kafushane sihlole ngayinye yalezi zilwane.

Mineral uvolo, noma kunalokho, mat kanye ipuleti ke, namuhla owande kakhulu. zifudumele ophahla nge mineral uvolo Kungashiwo kufanele kubhekwe kuyikhambi elingcono kakhulu le nkinga. Njengoba has a Coefficient eliphansi conductivity ezishisayo (of 0,032 ukuze 0,045 W / m × K), okuhle umusi permeability, ukwahlukanisa sound, ukuqina (iminyaka engaba ngu-50) futhi kuyaqina. Futhi, ayiyikuphuma ngokuphelele emanzini ukumuncwa futhi has a ukumelana umonakalo lokukhanda. Futhi isici esibaluleke kunazo zonke amaminerali uvolo - ukuthi has a flammability ongaphakeme.

Cishe izici ezifanayo kanye ingilazi, nakuba okuningi ukumuncwa amanzi umhwamuko ukudluliswa izinga lingaphansi kakhulu. Ukuze uthole umphumela efanayo kusuka amaminerali uvolo, kungenzeka ukuba vimbela ophahleni idwala uvolo, ngenxa impahla yayo, lokhu kuyefana kakhulu izakhiwo yezimbiwa.

Roof wokuvimbela polystyrene extruded Foam kusengathiwa futhi kukho okuhle. It has a conductivity ongaphakeme ezishisayo (0.02 kuya 0,035 W / m × K), isisindo amancane, kakhulu, izindleko iphansana. Kungezwe ngezithako zawo lwekhemikhali ethile okufakiwe wamenza impahla cishe yizona ezisetshenziswa kabanzi nokuzihlonipha, ngokuba nezingxabano zokucisha. Kukhona futhi ububi lolu hlobo ukwahlukanisa, isibonelo, ifa aphansi kakhulu umhwamuko permeability ukuthi lapho ukukhwezwa kahle ukupholisa kungaholela anda nomswakama ophahleni isakhiwo. Futhi, polystyrene has kuyaqina ongaphakeme futhi kuyaqina okusezingeni eliphezulu ukuthi ayikuvumeli ukusetshenziswa kwayo okuthiwa "ukufulela pie" ukufakwa isakhiwo ophahleni ukucupha.

Ngesisekelo amapulasitiki foamed, kukhona olunye uhlobo ezibonakalayo, ezingashabalala ngokuvamile akhiqiza ukwahlukanisa of ophahleni - a Foam polyurethane. izici zayo ezinhle yilezi ezilandelayo: anda ukumelana egqwalisayo, olubanzi izinga lokusebenza ezahlukene (kusuka -180 kuya +250 ° C). Okumbi - kuyinto ebucayi ukuqondisa kwelanga azinakho, ngoba lokho kuyadingeka ukuze zakhele enamathela zokuzivikela. Lolu hlobo kusetshenziswa ukuvumela kokubili nokunamathisela athutha uzilondoloze kwamanzi oyifunayo, futhi ukuba bafeze sishaye yayo. Kuyinto kuphela izinhlobo ezinkulu foamed polymer impahla, kukhona nabanye abaningi.

zifudumele of kophahla nge nomphumela microcameras, zazo zigcwele umoya, mhlawumbe impahla wezinto ezingaphili othiwa ukhonkolo yeselula. Yebo, noma kanjani, akungabazeki akunakubangelwa "usuku lwayizolo." Kodwa ukusetshenziswa organic fibre ukwahlukanisa, okuncike kukakhokho, kungcono ukuba nombono ongafani ngeke eduze eside ubuchwepheshe ukwakhiwa. Kodwa namuhla Liyindawo injabulo ezibizayo.
