Ntau zaus, bitumen emulsion yog siv rau saum npoo ntawm asph alt thiab waterproofing ntawm ntau yam qauv - ib hom ntawm cov khoom nyob rau hauv uas cov hais ntawm lub ntsiab tivthaiv tau nthuav tawm nyob rau hauv lub aqueous theem nyob rau hauv daim ntawv ntawm cov khoom sib cais. Yog li hais tias xws li ib puag ncig tsis muaj cov nyhuv gluing, txhua yam ntawm cov additives yog nquag siv - emulsifiers. Nws tsis tuaj yeem tsis lees paub tias bituminous waterproofing muaj txiaj ntsig zoo ntawm kev txuag nyiaj thiab kev phooj ywg ib puag ncig. Feem ntau, cov kws tshaj lij hauv cov txheej txheem ntawm kev ua haujlwm ntsib cov npe sib txawv ntawm cov khoom siv hauv paus. Nyob rau hauv cov ntaub ntawv no, lub resulting compositions yuav txawv heev ntawm ib leeg nyob rau hauv cov khoom.
Txhua qhov bituminous emulsion yuav tsum tau ntxiv cov kuab tshuaj, thiab nws cov nyiaj yuav tsum yog qhov tseeb. Txwv tsis pub, nag lossis daus ntawm tus kheej cov khoom lossis kev sib cais ntau dhau ntawm qhov sib tov yuav tshwm sim. Cov kuab tshuaj yog siv los ua tus neeg sawv cev uas txo qhov degree ntawm viscosity ntawm cov muaj pes tsawg leeg. Hais txog cov dej uas muaj nyob rau hauv xws li waterproofing, cationic mixtures yog tsawg rhiab heev rau ntxiv ntim dua anionic counterparts. Qhov kawg ntawm lawvhnov mob hnyav heev rau tus nqi ntawm impurities muaj nyob rau hauv cov kua ntxiv.
Hauv kev tsim cov khoom sib xyaw, kev teeb tsa tshwj xeeb rau kev tsim cov bitumen emulsion yog siv, uas muaj cov qauv tsim. Nws muaj xws li: lub ntsiab chav tsev nrog ib tug colloid zeb, hluav taws xob tswj systems, dosing kab rau dej thiab bitumen, ntim rau khaws cia ntau yam ntaub ntawv, raws li zoo raws li cov kav dej thiab twj tso kua mis. Kev ua haujlwm yog ua raws li lub hauv paus ntsiab lus ntawm kev sib xyaw ua ke, uas txhais tau hais tias ntxiv emulsification ntawm cov muaj pes tsawg leeg. Qhov zoo ntawm cov khoom kawg yog nyob ntawm qhov homogeneity ntawm qhov sib tov thiab kev kho ua ntej.
Xyaum txhua yam khoom siv yog ua los ntawm cov khoom tsis muaj corrosive, uas tso cai rau kom ua tiav lub neej kev pabcuam siab tshaj plaws. Qhov no yog qhov tseeb tshwj xeeb ntawm cov units thiab qhov chaw uas muaj kev sib cuag ncaj qha nrog cov dej hauv dej. Tam sim no, tsuas yog siv cov cuab yeej siv hluav taws xob, uas ua rau nws tuaj yeem tau txais cov khoom lag luam zoo thaum cov bitumen emulsion ua tau raws li txhua qhov yuav tsum tau ua. Qhov ntau thiab cov yam ntxwv ntawm cov khoom yog ntsuas los ntawm cov sensors tshwj xeeb. Raws li qhov tseeb tias cov khoom ntawm cov khoom sib tov tiav nyob ntawm emulsifiers, cov khoom siv tshwm sim hauv kev tsim khoom uas tuaj yeem nqus cov khoom hauv ob qho kev qhia.
Ua ntej cov bituminous emulsion yog siv rau saum npoo, lub substrate yuav tsum tau ua tib zoo npaj. Ua li no, lawv tau tshem ntawm cov txheej qub thiab ntau yam khib nyiab los ntawm leveling potholes loj dua pebmillimeters. Tom ntej no, priming yog nqa tawm nrog ib tug emulsion muaj pes tsawg leeg. Hom ntawm qhov chaw yuav tsum tau kho muaj qhov tshwj xeeb ntawm kev noj cov khoom sib tov. Saib ntawm lub ntim, koj tuaj yeem pom qhov nruab nrab ntawm cov khoom siv. Thaum cov dej los ntawm cov tshuaj evaporates, ib zaj duab xis nyias ntawm bitumen yuav nyob twj ywm rau saum npoo, tiv thaiv cov txheej tom ntej.
