Raws li lub hauv paus tseem ceeb ntawm lub tsev vov tsev, cov vuas vov tsev tsis yog tsuas yog muab vaj tse los ntawm nag thiab cua xwb tab sis kuj cuam tshuam ncaj qha rau lub tsev ruaj khov, zoo nkauj, thiab ib puag ncig adaptability. Cov ntaub ntawv sib txawv ntawm cov pobzeb muaj cov yam ntxwv ntawm lub cev, cov txheej txheem tsim kho, thiab cov xwm txheej siv tau; Kev xaiv kev tshawb fawb yog qhov yuav tsum tau ua ua ntej kom ntseeg tau lub sijhawm ntev - lub sijhawm txhim khu kev qha ntawm lub ru tsev.
Cov vuas av ib txwm yog tsim los ntawm cov av nplaum ntuj, tsim, qhuav, thiab raug rho tawm haujlwm ntawm qhov kub thiab txias. They are dense, have low water absorption, and possess good weather resistance and fire resistance. Lawv cov xim feem ntau yog xim liab-xim av lossis xiav- grey, sib xyaw zoo nrog cov tsev keeb kwm thiab cov tsev nyob ib txwm muaj. Txawm li cas los xij, cov vuas av nplaum kuj hnyav heev, yuav tsum muaj lub siab - lub zog lub ru tsev, thiab nkig, yooj yim tawg thaum muaj kev cuam tshuam.
Cement vuas yog tsim los ntawm kev sib xyaw thiab nias silicate cement, xuab zeb, thiab fiber ntau cov ntaub ntawv, tom qab ntawd kho thiab ua kom tawv nqaij. Cov khoom siv no muaj tus nqi nruab nrab, lub zog siab, thiab tuaj yeem ua rau ntau yam textures thiab xim kom tau raws li kev xav tau ntawm ntau hom kev tsim qauv niaj hnub. Thaum muaj cov dej tsis zoo, qhov tev tawm tuaj yeem tshwm sim nyob rau hauv ntev - lub sij hawm khov - thaw cycles, yuav tsum tau xyuam xim rau kev tiv thaiv nto.
Cov vuas av nplaum, raws li cov av nplaum, suav nrog kev tswj qhov kub thiab txias thiab ntxhia sib piv. Lawv qhov kub hnyiab yog feem ntau siab dua li cov av nplaum zoo tib yam, txhim kho qhov ntom ntom thiab impermeability thaum khaws cov xim ntuj thiab ua pa, pab tswj cov av noo hauv tsev. Cov vuas av nplaum muaj qhov zoo nkauj zoo nkauj thiab zoo nkauj zoo nkauj, haum rau siab -cov tsev nyob thiab kab lis kev cai, tab sis lawv cov txheej txheem ntau lawm ua rau cov nqi siab dua.
Asphalt shingles siv fiberglass ua cov khoom siv hauv paus, coated ntawm ob sab nrog hloov asphalt thiab xim pob zeb hauv av granules. Lawv yog lub teeb yuag thiab hloov tau yooj yim, yooj yim rau nruab rau ntawm lub ru tsev tsim, thiab muab kev tsim kho siab. Lawv muaj kev ua dej tsis zoo thiab muaj ntau yam xim, feem ntau siv hauv qis-nce lossis ntau- cov vaj tse sloped. Txawm li cas los xij, asphalt shingles tau txwv siab - qhov kub thiab txias tsis kam thiab UV tiv thaiv, ua rau lawv lub neej luv luv nyob rau hauv cov cheeb tsam uas muaj hnub ci zog thiab kub siab.
Synthetic resin vuas siv high-molecular polymers (xws li PVC thiab ASA) raws li cov ntaub ntawv raw, co-extruded, combining zoo xws li lub teeb yuag, corrosion kuj, thiab ntev - xim. Lawv kuj yog ib qho yooj yim rau nruab, haum rau lub teeb steel qauv lossis lub tsev ib ntus. Txawm li cas los xij, nws qhov kev tiv thaiv hluav taws thiab kev cuam tshuam yuav tsum tau ua kom zoo raws li cov qauv, thiab kev saib xyuas yuav tsum tau them rau qhov kev pheej hmoo ntawm qis - kub embrittlement hauv cheeb tsam txias.
Hlau vov tsev vuas yog ua los ntawm cov ntaub ntawv xws li txhuas, tooj liab, thiab zinc alloys, thiab yog dov los yog molded rau hauv pobzeb duab. Lawv yog lub teeb yuag, siab - lub zog, rov ua dua tshiab, muaj lub neej ntev, thiab cov nqi kho mob qis, thiab feem ntau yog siv hauv cov tsev niaj hnub minimalist lossis loj loj. Cov vuas hlau vov tsev muaj cov thermal conductivity siab, yog li yuav tsum tau them nyiaj rau qhov tsim ntawm thermal rwb thaiv tsev kom tsis txhob muaj cua sov thaum lub caij ntuj sov.
Hauv cov ntsiab lus, kev xaiv cov ntaub ntawv pobzeb vov tsev yuav tsum yog raws li qhov sib npaug ntawm huab cua, lub tsev thauj khoom, kev xav kom zoo nkauj, thiab tag nrho lub neej- tus nqi voj voog kom ua tiav qhov zoo tshaj plaws ntawm kev ua haujlwm thiab cov txiaj ntsig.
