Dab tsi yog Dawb Bitumen: Specifications + Daim Ntawv Thov
Thaum cov neeg feem coob paub txog dub bitumen, muaj lwm qhov txawv hu ua dawb bitumen, uas feem ntau yog siv los ua cov ntaub thaiv dej. Hom bitumen no muaj cov khoom siv dej tsis zoo thiab qhia qee yam tseem ceeb nrog cov bitumen dub, xws li siab viscosity thiab muaj zog adhesiveness. Nws cov khoom tshwj xeeb ua rau nws tsim nyog rau ntau yam kev siv, suav nrog kev tsim kho thiab cov ntaub thaiv dej tsis zoo, nrog rau kev tsim cov yas, xim, yeeb nkab rwb thaiv tsev, thiab asphalt. Tsab ntawv xov xwm no los ntawm BASEKIM muab kev nkag siab zoo rau cov neeg ua haujlwm hauv pej xeem, cov kws tshawb fawb, thiab cov kws tshaj lij kev lag luam txaus siab rau cov txiaj ntsig thiab kev siv ntawm cov tshuaj dawb bitumen.
Dawb bitumen yog dab tsi?
Dawb bitumen, tseem hu ua camphor bitumen, albokarbon, los yog naphthalene, yog ib qho khoom muaj ntxhiab hydrocarbon muab tau los ntawm thee. Nws muaj nuj nqis rau nws cov adhesiveness siab, tensile zog, thiab waterproofing zog, ua rau nws yog ib qho tseem ceeb cov ntaub ntawv nyob rau hauv kev tsim kho, industrial txheej txheem, thiab manufacturing. Vim tias nws cov tshuaj lom neeg ruaj khov thiab muaj peev xwm ua tau zoo, cov bitumen dawb tam sim no feem ntau siv nrog rau cov khoom xws li Tom ntej: Bitumen MC70 nyob rau hauv asphalt thiab waterproofing daim ntaub ntawv.
Keeb kwm ntawm Dawb Bitumen
Thawj qhov kev txheeb xyuas ntawm cov bitumen dawb tau tshwm sim hauv xyoo 1819 thaum lub sijhawm kev sim ntawm cov thee distillation. Ob peb xyoos tom ntej no, cov kws tshawb fawb tseem ceeb xws li John Kidd, Michael Faraday, thiab Emil Erlenmeyer tau kawm txog nws cov khoom thiab kev coj tus cwj pwm, thaum kawg txiav txim siab nws cov qauv tshuaj. Los ntawm thaum ntxov mus rau ib nrab xyoo pua, kev paub txog dawb bitumen thiab nws cov kev siv peev xwm tau nthuav dav thoob ntiaj teb, paving txoj kev rau nws siv nyob rau hauv kev tsim kho, waterproofing, thiab manufacturing txheej txheem.
Specification ntawm Dawb Bitumen
Dawb bitumen cov yam ntxwv tshwj xeeb yog vim muaj kev sib xyaw ntawm cov tshuaj lom neeg, cov khoom siv ntxiv, thiab cov yam ntxwv ntawm lub cev uas paub qhov txawv ntawm cov tsoos dub bitumen.
Tshuaj Muaj pes tsawg leeg
Dawb bitumen yog tsim los ntawm cov tsoos dub bitumen. Nws lub teeb xim txawv yog ua tiav los ntawm kev ua haujlwm tshwj xeeb. Cov neeg tsim khoom feem ntau siv cov xim xim xim, xws li limestone lossis titanium dioxide, tig cov bitumen los ntawm tsaus rau xim dawb thaum khaws nws cov khoom yooj yim, xws li viscosity, adhesiveness, thiab waterproofing peev xwm. Nws yog feem ntau muab nkag rau hauv qib xws li Bitumen muaj 115/15, uas ua kom muaj kev sib xws hauv kev lag luam thiab kev tsim kho.
additives
Dawb bitumen yuav muaj ntau yam additives los txhim kho kev ua haujlwm. Polymers feem ntau yog siv los ua kom yooj yim thiab txo qis degradation nyob rau lub sijhawm. UV stabilizers kuj tseem pab tiv thaiv cov khoom siv los ntawm kev puas tsuaj ntawm lub hnub ci, ua rau nws lub neej ntev thiab kev ntseeg siab hauv kev siv sab nraum zoov.
Lub Cev Lub Cev
Dawb bitumen sawv tawm vim nws lub teeb xim, uas qhia txog lub hnub ci thiab txo qhov nqus cua sov. Nws kuj muaj cov nplaum nplaum siab, yoog raws, thiab huab cua tsis kam, ua rau nws yog cov khoom siv zoo tshaj plaws rau kev tsim kho, cov dej tsis zoo, cov yeeb nkab rwb thaiv tsev, thiab lwm yam kev siv hauv kev lag luam.
