Rooferoid yog nrov heev nrog cov neeg siv khoom, txawm hais tias tam sim no muaj ntau cov ntaub ntawv pov thawj thiab cov ntaub ntawv vov tsev. Qhov no tau piav qhia, feem ntau, los ntawm kev pheej yig ntawm cov khoom siv vov tsev thiab qhov yooj yim ntawm nws cov installation. Tsis tas li ntawd, cov khoom no tsuas muaj cov yam ntxwv ua tau zoo heev.
Siv cov khoom siv vov tsev rau lub ru tsev ntawm txhua lub tsev, rau kev tiv thaiv kev tiv thaiv ntawm cov hauv paus, cav, kab teeb, thiab lwm yam.
Thaum twg lawv pib siv cov khoom vov tsev?
Cov khoom no tau pib siv hauv kev tsim kho hauv xyoo pua 17th. Tom qab ntawd cov ru tsev tau pw nrog cov ntawv tshwj xeeb, uas yog tom qab ntawd nchuav nrog kub tar. Thaum pib ntawm lub xyoo pua nees nkaum, lawv pib tsim cov khoom siv vov tsev, tsim los ntawm bituminous mastics. Tam sim no, muaj ob peb hom ntawm cov khoom siv vov tsev no. Hauv paus, cov khoom siv vov tsev yog muab faib ua hauv ob sab phlu thiab vov tsev. Hauv kev tsim khoom ntawm hom thib ob, siv cov ntawv tuab tuab thiab hnav khaub ncaws ntxhib.
Rouberoid manufacturing process
Lub tshuab tsim cov khoom siv vov tsev yog yooj yim heev thiab muaj nyob rau hauvraws li hauv qab no: ib txheej ntawm vov tsev ntawv yog pre-impregnated nrog mos roj av bitumen, ces ib txheej ntawm refractory bitumen yog siv rau ob sab ntawm daim ntawv resulting. Sab saum toj yog xuab zeb.
Qhov tshwm sim yog cov khoom siv tiv thaiv dej tsis zoo hu ua vov tsev. Cov khoom siv vov tsev thiab hauv ob sab phlu tuaj yeem sib txawv ntawm cov thickness ntawm cov txheej txheej bituminous. Cov khoom siv hauv qab no tau tsim tawm tam sim no:
- RKP-300, RPK-350. Cov khoom siv vov tsev no yog mos thiab siv tau rau ob sab saum toj thiab hauv qab vov tsev.
- RPP-300. Sab hauv hom txheej nrog plua plav, hnav khaub ncaws zoo heev. Siv ua txheej hauv qab ntawm lub ru tsev mos.
- RKK-400. Thick ruberoid nrog coarse hnav khaub ncaws. Siv ua txheej saum toj kawg nkaus ntawm lub ru tsev mos.
- RKP-350U. Qhov no yog zoo tib yam rau RKP-300, tab sis nrog ib tug thicker bituminous txheej ntawm vov tsev cov ntaub ntawv. Views tuaj yeem ua raws li thickness.
Dab tsi yog hu ua cov khoom vov tsev?
Cov khoom siv vov tsev kuj suav tias yog vov tsev iav thiab cov ntawv ntim cov ntawv ntim. Cov tom kawg yog siv los qhwv ntau yam ntawm cov pob qij txha thiab qhov chaw. Glassine yog siv los tiv thaiv lub ru tsev raws li qhov qis, thawj txheej ntawm cov ntaub pua plag tiv thaiv. Cov khoom siv vov tsev, cov hom uas muaj ntau haiv neeg, kuj tau nthuav tawm hnub no hauv cov kua ua kua. Nws tuaj yeem siv tau rau tib lub sijhawm li ib txwm muaj. Siv nws nrog txhuam los yog ib tug menyuam. Tom qabhardening kua vov tsev cov ntaub ntawv ua ib tug nruam tuab ntaub pua plag uas ntseeg tau los tiv thaiv ntau yam nto los ntawm ya raws.
Cov khoom siv vov tsev
Cov khoom siv vov tsev (hom tsis muaj teeb meem) ib txwm muab tso rau ntawm qhov qhuav, txawm tias lub hauv paus, yav tas los primed nrog bitumen diluted hauv roj av. Cov ntaub yog pw nrog ib qho sib tshooj ntawm txog kaum centimeters. Cov khoom siv vov tsev yog glued ntawm bituminous mastic. Qhov yooj yim tshaj plaws los siv tus kheej-nplaum cov ntaub ntawv vov tsev. Hom ntawm cov khoom no yog tiv thaiv nyob rau hauv underside nrog ib zaj duab xis los yog ntaub, uas yuav tsum tau muab tshem tawm ua ntej installation.
Cov khoom siv vov tsev yog cov khoom siv txhim khu kev qha, yooj yim rau nruab thiab thauj khoom. Qhov no piav qhia txog nws qhov kev nyiam nyob ntev nrog cov tswv tsev ntiag tug.
