Denga: The denga pamuromo, Select Material

Roof - ari goko reimba, iro anodzivirira kuvaka pamusoro kupinda pakati kunonaya. Roof inofanira isapinda, pasi chafariz conductivity uye husingakwanisi nehasha makemikari uye kunayisa. Nokuti mukugadzira ari nemakadhibhokisi kushandisa dzakasiyana zvinhu - Organic, esimbi kana zvicherwa. Mumwe mhando nemakadhibhokisi zvakasiyana kuita uye basa upenyu, vamwe vanogona kugara makore 5-7, uye chero uye 100. Funga mumwe mhando nomumwe padenga.

Organic.

Data kuzvinhu zvokuvakisa dzinozivikanwa kudanda yekare, mashanga, shingles, uyewo zvinhu ano - bhitumini-polymer nezvakavhenganiswa, akakungurutsa zvokuvakisa, Asphalt, uye dzimwe Polymers.

zvayakanakira:

• ivo lightweight.

nezvayakaipira:

• zvakaneta kurwisa ultraviolet mwaranzi uye okisijeni,
• kuchembera makasimba,
• kukwanisa nekuwora,
• zvikuru inflammable.

The upenyu basa 5 kusvika 30 makore.

Mineral.

Iri boka guru, rinosanganisira pabhodhi Tile, zvedongo Tile uye simende-jecha, asbestos-simende machira (asbestos) uye usina kukonekita. Izvi kuzvinhu zvokuvakisa vari vaakadanawo zvakasikwa.

zvayakanakira:

• tora nguva refu
• vimbika
• regai kuora,
• asingaiti vesa,
• kwete kuparadzwa nechiedza chezuva.

nezvayakaipira:

• Ini ndiri chaizvo nehanya tembiricha, kunyanya kuwanda razero inegumi,
• vane wandei uremu,
• kwete inowanzoshandiswa nokuda pfupi kudhura.

Metal.

Izvi zvinosanganisira simbi chemarata machira, simbi, nemakadhibhokisi, non-ferrous simbi. Nokuti avo kugadzira mhangura, aruminiyamu, kwakakurudzira simbi, uye vatema, uyewo alloys ayo, izvo ruvara varnish, lacquer, pendi, polymer zvinhu. Copper machira ndivo kupfuura yakasimba. Upenyu denga mhangura 50 kusvika 100 nemakore.

Ivai pasi uremu. Pakuvaka maindasitiri, paruzhinji uye vezvokutengeserana kushandiswa zvakananga simbi machira. Kazhinji, zvokushandisa zviri padenga remba ane murwere kubva 14 kusvika 20 madhigirii, machira ane Ukobvu 0.5 - 0,8 neMM, zvemapuranga kumativi ose pamwechete zinc. Kuisa jira simbi Kumbofungatira michina wakaitwa, saka izvi anonzi kumira musono padenga. Denga rinofanira vakagadzirira vashandi chete unyanzvi. Kuramba izvozvo akatanga kutsiva simbi pamwe titanium, mhangura, aruminiyamu. Copper, kunyange zvinodhura, asi ane kunoshamisa mapurani mashoko uye kwazvo mukurumari. Metal nemakadhibhokisi yaigadzirwa kwakakurudzira simbi, uye dzimwe nguva akaita nemhangura. Zvinogona zvinenge zvakazara kweimwe ngura nedziviriro, mune imwe kana mbiri akaturikidzana kuti polymeric unhani. The polymeric bemhapemha iri husingakwanisi ultraviolet mwaranzi uye mishonga zvingava Mat kana kupenyerera. Metal Zvinokosha zvakaisvonaka uye lightweight, anoiswa padenga pamwe pamateru kupfuura madhigirii 12.
