Vim hais tias muaj ntau yam ntawm ntau yam, asphalt sib xyaw nroj tsuag yuav inevitably muaj teeb meem tom qab siv. Vim tias tsis muaj kev paub dhau los, lawv tsis paub yuav ua li cas nrog cov teeb meem no. Tus kws kho xwm txheej tsis meej pem qee yam kev paub dhau los thiab kev txawj hauv qhov no rau koj siv.

Raws li cov teeb meem sib txawv ntawm cov teeb meem ntawm asphalt mixing tsob nroj, kev daws teeb meem kuj txawv. Piv txwv li, thaum seem ntawm cov asphalt sib tov cog yog nkees lawm puas, nws yog qhov tsim nyog los pib ntawm kev tsim cov ntu. Ntawm ib sab tes, nws yog qhov tsim nyog los txhim kho qhov chaw tiav ntawm cov ntu. Ntawm qhov tod tes, lub hom phiaj ntawm kev txo cov kev ntxhov siab ntawm cov ntu tuaj yeem ua tiav los ntawm kev coj tus neeg hla kev sib deev. Tsis tas li ntawd, kev ua tau zoo ntawm cov ntu tuaj yeem hloov kho los ntawm carburizing, quenching thiab lwm txoj kev, thiaj li ua kom tiav cov nyhuv ntawm kev puas tsuaj ntawm feem.
Tab sis yog tias kev puas tsuaj ntawm cov seem hauv asphalt sib tov cog yog vim kev sib txhuam, yuav ua li cas? Qhov yooj yim tshaj plaws thiab cov khoom siv yooj yim tshaj plaws yog siv cov khoom siv-resistant cov khoom siv ntau li ntau tau, thiab thaum tsim cov duab ntawm cov kab sib xyaw ua ke, sim txo nws cov kev sib txhuam. Tsis tas li ntawd, corrosion kuj tseem yog ib qho ntawm cov laj thawj uas ua rau muaj kev puas tsuaj. Hauv qhov no, koj tuaj yeem siv npib tsib xee, chinc thiab lwm cov khoom siv corrosion, thiab siv cov xim hlau ntawm cov av uas tsis tiv thaiv kab mob corrosion.
