stirring yog ib qho tseem ceeb ua ntej daim ntawv thov txheej txheem rauEmulsified asphalt kua, ncaj qha txiav txim siab emulsion homogeneity, emulsifying kev ua ub no thiab kev tsim kho tom ntej. Tsis yog-tus qauv nplawm ua haujlwm yooj yim ua rau emulsion stratification, emulsification tsis ua haujlwm thiab ua haujlwm tsis sib haum. Yog li ntawd, ntau yam ntaub ntawv npog cov khoom siv, nplawm tshaj tawm, kev ua haujlwm, cov ntaub ntawv pabcuam thiab cov xwm txheej ib puag ncig yuav tsum tau tswj hwm thoob plaws hauv cov txheej txheem sib xyaw. Hais txog cov cuab yeej siv thiab cov qauv nplawm, cov cuab yeej siv tes ua haujlwm tsis zoo rau kev sib tsoo ceev yog txwv. Tshwj xeeb qis-ceev sib xyaw tshuab txuam nrog emulsion nta ntawm Emulsified Asphalt Liquid yuav tsum tau siv.
Emulsified Asphalt Liquid belongs rau nplua aqueous emulsion. High-speed stirring draws huab cua loj rau hauv cov kua thiab ua kom muaj npuas ntau. Foam residues tsim qhov pores thiab hollow me ntsis ntawm cov pavements tiav, txo qis compactness thiab bonding zog. Tsis tas li ntawd, kev kub ntxhov siab ua rau cov khoom sib npaug hauv cov emulsion thiab ua rau cov demulsification ntxov ntxov, flocculation thiab caking, ua rau cov khoom siv tsis raug. Paddle-type low-speed mixing equipment yuav tsum siv nrog kev sib hloov tsis tu ncua. Kev sib xyaw paddles yuav tsum ncav cuag hauv qab thiab sab phab ntsa ntawm cov thawv kom tshem tawm cov kab tuag tuag thiab paub meej homogenization ntawm emulsion thoob plaws lub nkoj.
Tom qab ntawd los txog kev npaj ua ntej stirring. Tshawb xyuas thawj lub xeev ntawm Emulsified Asphalt Liquid ua ntej pib sib tov. Me me hauv qab nag lossis daus thiab ib txheej nyias nyias sab saum toj tom qab static cia suav raws li ib txwm tshwm sim thiab tsis teeb liab teeb meem. Tsis txhob siv tsuas yog cov kua dej sab saud lossis cov dej hauv qab ntawm cov av; stirring yog xav tau rau tag nrho homogenization. Ntxuav cov hlab ntsha thiab paddles ua ntej, kom tsis txhob muaj roj stains, khib nyiab lossis cov khoom qub uas nyob hauv cov khoom siv. Cov impurities sib xyaw rau hauv emulsion yuav ua rau cov tshuab emulsion puas tsuaj thiab ua rau lub zos demulsification thiab caking, rhuav tshem tag nrho kev tsim kho zoo.
Stirring tshaj tawm thiab ncua sij hawm sawv cev rau cov tseem ceeb tswj kev sib txuas. Emulsified Asphalt Liquid yuav tsum tau muab sib xyaw ntawm tus nqi qis qis uas tsis muaj kev txhawb nqa. Tsis yog luv luv lossis ntev ntev sib xyaw ua ke tau txais. Kev nplawm tsis txaus tsis tuaj yeem rhuav tshem cov precipitates kiag li thiab ua rau qhov tsis sib xws ntsug ntawm cov emulsion, ua rau cov pavement thickness tsis sib haum thiab kev sib txuas ua haujlwm tom qab kev tsim kho. Tshaj-ntev nplawm tsis tu ncua cuam tshuam emulsion systems, destabilizes nto-active cov khoom xyaw thiab coj emulsion laus thiab kev ua haujlwm degradation. Rau static-stored Emulsified Asphalt Liquid, peb mus rau tsib feeb ntawm kev sib tov feem ntau ua tiav ib homogeneous.
Ua raws li cov txheej txheem nruj-ntxiv thaum nplawm. Txwv tsis pub sib xyaw cov khoom tsis raug cai. Tsis txhob nchuav dej tshiab, cement lossis lwm yam khoom sib xyaw ua ke thaum sib tov. Cov khoom uas muaj pH sib txawv thiab cov tshuaj muaj pes tsawg leeg hnov mob nrog Emulsified Asphalt Liquid, tam sim ntawd tawg emulsification tshuav nyiaj li cas thiab ua rau demulsification, stratification thiab tag nrho cov khoom scrapping. Yog tias yuav tsum tau dilution rau lub hom phiaj kev tsim kho, ua raws li cov txheej txheem kev ua haujlwm-txoj cai thiab ua raws li kev npaj raws li qhov sib piv thiab cov txheej txheem kev siv tsis yog qhov muag tsis pom kev sib xyaw.
Saib xyuas cov xwm txheej emulsion hauv tag nrho cov txheej txheem sib xyaw. Tshem tawm nplawm thaum cov xim tsis sib xws thiab viscosity tiav yam tsis muaj caking, stratification lossis ua npuas ncauj ntau dhau. Siv cov khoom sib xyaw zoo Emulsified Asphalt Liquid rau kev tsim kho sai li sai tau, rau qhov chaw nyob ntev li qub tom qab nplawm yuav ua rau rov stratification thiab nag lossis daus. Cov txheej txheem tag nrho cov txheej txheem nplawm ua kom muaj txiaj ntsig zoo ntawm cov khoom muaj txiaj ntsig ntawm Emulsified Asphalt Liquid, txhawb nqa txawm tias txau thiab txhuam cov haujlwm thiab xa cov pavement-forming zoo.
