Ru: Lub-ru tsev brim, Xaiv Khoom

Ru - yog ib tug plhaub ntawm lub-ru tsev, uas tiv thaiv lub tsev tiv thaiv cov allergic ntawm dej nag. Ru tsev yuav tsum waterproof, tsis tshua muaj thermal conductivity thiab resistant mus txhoj puab heev tshuaj thiab nag lossis daus. Rau raug lub vov tsev siv ntau yam ntaub ntawv - organic, nws yog xim hlau los yog mineral. Txhua yam ntawm vov tsev sib txawv kev ua tau zoo thiab cov kev pab lub neej, ib txhia yuav kav 5-7 xyoos, thiab tej yam thiab 100. Xav txog txhua yam zuj zus-ru tsev.

Organic.

Cov ntaub ntawv ru tsev ntaub ntawv yog lub npe hu mus rau lub ancient ntoo, straw, shingles, raws li zoo li niaj hnub cov ntaub ntawv - bitumen-polymer sib tov, dov tej ntaub ntawv, asphalt, thiab lwm yam polymers.

pros:

• lawv yog sib.

cons:

• weakly tawv ultraviolet rays thiab cov pa,
• laus ceev,
• tau lwj,
• mas inflammable.

Cov kev pab cuam lub neej ntawm 5 mus rau 30 xyoo.

Mineral.

Qhov no yog ib tug loj pawg, uas muaj xws li slate pobzeb, tej hub pobzeb thiab xis mas xuab zeb, asbestos-xis mas los xij (asbestos) thiab cov vuas. Cov vov tsev cov ntaub ntawv kuj hu ua ntuj.

pros:

• check
• txhim khu kev qha
• tsis rot,
• tsis zes,
• tsis puas los ntawm tshav ntuj.

cons:

• Kuv rhiab heev rau kub, tshwj xeeb tshaj yog nyob rau hauv lub chav xoom degrees,
• muaj ib tug txiav txim hnyav,
• tsis yog feem ntau siv vim lub siab kuj nqi.

Hlau.

Cov no muaj xws hlau corrugated los xij, hlau, vuas vov tsev, uas tsis yog-ferrous hlau. Rau lawv raug tooj liab, txhuas, galvanized steel, thiab dub, raws li zoo raws li alloys thereof, uas yog dyed cov kua roj vanish, lacquer, xim, polymer cov ntaub ntawv. Tooj los xij yog cov feem ntau check. Lub neej ntawm cov tooj liab ru tsev los ntawm 50 mus rau 100 xyoo.

Muaj ib tug uas tsis muaj ceeb thawj. Nyob rau hauv kev tsim kho ntawm muaj, pej xeem thiab coj mus muag siv ncaj qha hlau los xij. Feem ntau, cov khoom siv ntawm lub ru tsev ntawm lub ru tsev nrog ib tug nruab nrab kem ntawm 14 mus rau 20 degrees, nplooj ntawv nrog ib tug tuab ntawm 0.5 - 0.8 hli, loj rau ob sab nrog zinc. Installation ntawm daim ntawv hlau folding tshuab tuav, yog li no yog hu ua sawv leeg ru tsev. Lub-ru tsev yuav tsum muab nruab tsuas txawj ua hauj lwm. Qhia nws pib mus rau hloov steel nrog titanium, tooj liab, tooj dawb. Tooj, txawm hais tias nws yog kim, tab sis muaj ib tug zoo heev architectural qhia thiab zoo heev durability. Hlau vov tsev ua los ntawm galvanized steel, thiab yog tej zaum ua los ntawm tooj liab. Nws tej zaum yuav loj nrog ib tug ntxiv xeb tiv thaiv, nyob rau hauv ib los yog ob khaubncaws sab nraud povtseg ntawm polymeric txheej. Lub polymeric txheej yog resistant rau ultraviolet rays thiab tshuaj tej zaum yuav matt los yog ci iab. Hlau check thiab khaub-ncaws nyias, yog muab tso rau saum lub ru tsev nrog ib tug nqes hav ntau dua tshaj 12 degrees.
