Hauv kev saib xyuas kev tiv thaiv kev loj,micro-surfacingthiab cationicasphalt emulsified uas teeb sai saisawv cev rau cov thev naus laus zis kho txoj kev uas muaj txheej nyias nyias zoo tshaj plaws. Raws li lub hauv paus tseem ceeb hauv lub kaw lus asphalt emulsified, emulsifiers tswj hwm ncaj qha rau kev ruaj khov ntawm emulsion cia, kev sib txuas ntawm asphalt thiab aggregates, kev sib xyaw ua ke ntawm cov khoom sib xyaw, thiab lub sijhawm xav tau rau txoj kev qhib rau tsheb tom qab kev tsim kho. Cov haujlwm txoj kev hauv Suav teb raug kev cov nyom los ntawm ntau yam aggregate lithology, kev hloov pauv huab cua hauv cheeb tsam, thiab cov sijhawm tsim kho nruj. Lub cationic asphalt emulsifier nrog kev sib xws dav dav thiab kev ua haujlwm ruaj khov yog qhov tseem ceeb rau kev lav qhov zoo ntawm kev saib xyuas txoj kev thiab txo cov kev pheej hmoo ntawm kev tsim kho hauv qhov chaw.
Shanghai Qixuan Chemical tau tshwj xeeb hauv cov khoom siv tshuaj tshiab rau kev tsim kho txoj kev ntev lawm. QXME 87 cationic asphalt emulsifier yog cov khoom lag luam laus uas tau lees paub los ntawm kev sim tshuaj hauv chaw kuaj mob thiab ntau daim ntawv thov engineering. Nws yog tsim tshwj xeeb rau cationic quick-set (CQS) emulsified asphalt thiab micro-surfacing systems, xa cov kev daws teeb meem emulsification txhim khu kev qha rau cov haujlwm kho txoj kev hauv tsev.
QXME 87 yog ib qho amine-based cationic asphalt emulsifier nrog tus nqi amine tsawg kawg nkaus ntawm 370. Cov khoom xyaw amine nquag muaj ntau yam ua rau cov khoom muaj peev xwm emulsifying zoo heev thiab lub zog them, ua rau muaj kev ua haujlwm zoo ntawm cov asphalt hauv qab acidic. Cov khoom yog kua xim av, nrog qhov ceev ntawm 0.97 txog 1.05 g / cm3.³ thaum 25°C. Nws tswj tau qhov fluidity zoo ntawm qhov kub thiab txias thiab yooj yim rau kev pub mis yam tsis tau preheating thiab yaj. Nws sib xws nrog cov kab ntau lawm thiab cov kab tsim khoom asphalt emulsified tas mus li hauv Suav teb rau kev xa khoom, ntsuas thiab sib tov cov txheej txheem. Muaj cov khoom ruaj khov physicochemical, nws tiv taus stratification thiab nag lossis daus nyob rau hauv cov xwm txheej cia khoom ib txwm muaj, pab txhawb kev tswj hwm chaw rau cov chaw tsim khoom. Nws ua tau zoo txo qhov kev hloov pauv zoo ntawm emulsion los ntawm kev hloov pauv pub mis thiab ua kom muaj kev ua tau zoo ntawm emulsified asphalt los ntawm ib pawg mus rau ib pawg.
Tau txais txiaj ntsig los ntawm nws cov qauv molecular tsim tshwj xeeb, emulsified asphalt formulated nrog QXME 87 muaj ntau qhov zoo ntawm kev ua tau zoo.
Ua ntej, nws ua tiav qhov zoo tshaj plaws emulsion-rau-aggregate sib xws thiab haum rau cov pob zeb sib xyaw ntawm ntau yam lithologies thiab acid-base cov khoom. Cov pob zeb sib xyaw rau cov haujlwm txoj kev hauv tsev sib txawv ntau yam hauv cov tshuaj lom neeg ntawm qhov chaw, cov ntsiab lus ntawm cov av xuab zeb thiab kev huv. Ntau cov emulsifiers feem ntau raug kev txom nyem los ntawm kev tawg tsis tswj hwm thiab cov txheej txheem asphalt tsis sib xws thaum cov khoom noj khoom haus sib xyaw hloov pauv. Lub kaw lus emulsification ntawm QXME 87 qhia txog kev kam rau siab rau cov pob zeb sib xyaw sib txawv. Cov dej ntws asphalt emulsified tuaj yeem tsim cov yeeb yaj kiab asphalt sib xws thiab ntom ntom ntawm cov chaw sib xyaw, txhim kho qhov kev sib txuas ntawm asphalt thiab pob zeb. Nws txo qis kev ua tsis tiav ntawm kev tsim kho los ntawm cov khoom siv raw sib xyaw thiab txo qhov tshwm sim ntawm kev ua haujlwm dua tshiab.
Qhov thib ob, cov khoom sib tov no muaj kev sib xyaw zoo thiab ua haujlwm tau zoo. Thaum lub sijhawm sib tov cov khoom sib tov me me, qhov nrawm ntawm lub kaw lus tuaj yeem tswj tau zoo. Cov khoom sib tov no tswj tau lub sijhawm ua haujlwm kom zoo kom ntseeg tau tias kev ua haujlwm ntawm txoj kev paving du, zam kev sib sau ua ke thiab caking ua ntej lub sijhawm, thiab xyuas kom txoj kev tiaj tus tom qab muab tso rau.
Qhov thib peb, nws ua tau raws li qhov yuav tsum tau ua ntawm engineering rau kev qhib tsheb khiav ceev. Cov ntawv thov asphalt emulsified me me thiab cov ntawv thov asphalt emulsified uas teeb tsa sai feem ntau xav kom txoj kev rov qhib rau tsheb khiav sai tom qab kev tsim kho, ua kom lub sijhawm tswj kev khiav tsheb luv dua thiab txo qhov cuam tshuam ntawm kev ua haujlwm ntawm txoj kev rau kev khiav tsheb hauv cheeb tsam thiab lub neej txhua hnub ntawm cov neeg nyob ntawm txoj kev. Asphalt emulsified uas npaj nrog QXME 87 tawg thiab kho ntawm qhov nrawm tsim tom qab paving. Txoj kev tsim tau txais lub zog thaum ntxov sai sai thiab ua tau raws li cov lus qhia yuav tsum tau ua rau kev qhib tsheb khiav ceev.
Qhov thib plaub, cov asphalt emulsified tiav lawm muaj kev ruaj khov zoo heev. Cov emulsion tsim tawm tiv taus kev faib ua pawg thiab kev sib cais hauv lub sijhawm khaws cia uas tau teev tseg, ua rau lub sijhawm khaws cia thiab thauj mus los ntev dua rau cov emulsions tiav lawm. Nws kuj txo cov khoom pov tseg thiab kev phom sij ntawm kev tsim kho uas tshwm sim los ntawm kev ua tsis tiav ntawm emulsion ua ntej lub sijhawm.
Raws li kev sim ua cov tshuaj mus sij hawm ntev thiab kev tshuaj xyuas cov haujlwm hauv thaj teb, ob daim ntawv qhia txog kev siv rau QXME 87 tau muab tso ua ke hauv qab no. Lub pH ntawm ob lub tshuab tau kho rau 1.5–2.5 nrog hydrochloric acid, rau kev siv rau hauv kev npaj cov qauv kuaj thiab kev tsim khoom hauv kev lag luam.

Cov roj hmab latex yog ib qho khoom tseem ceeb hauv cov txheej txheem micro-surfacing kom txhim kho kev tiv thaiv kev hnav thiab kev tawg ntawm cov txheej txheem slurry seal. Cov mis no yog tsim rau kev saib xyuas micro-surfacing tiv thaiv ntawm cov kev loj thiab cov kev hauv nroog. Ob qho tib si cov mis no yooj yim siv rau ntawm cov kab tsim cov asphalt emulsified ib txwm muaj. Cov neeg siv khoom tuaj yeem kho cov tshuaj emulsifier dosage thiab cov mis piv nrog kev txhawb nqa kev tshaj lij los ntawm Shanghai Qixuan Chemical, phim cov kev xav tau ntawm cov haujlwm raws li cov qib asphalt xaiv, cov khoom sib sau ua ke thiab cov lus qhia txog kev tshaj lij.
Hais txog cov xwm txheej siv engineering, QXME 87 siv tau rau kev saib xyuas tiv thaiv thiab kev kho txoj kev thaum muaj xwm txheej ceev ntawm txoj kev loj, txoj kev loj hauv tebchaws & xeev, thiab txoj kev hauv nroog. Raws li kev daws teeb meem kev saib xyuas txheej nyias nyias nrog kev tsim kho sai, tus nqi nruab nrab, kev tiv thaiv dej thiab kev hnav tsis kam, micro-surfacing yog cov thev naus laus zis nyiam rau kev kho cov teeb meem ntawm txoj kev thaum ntxov. Cationic quick-set emulsified asphalt tau siv dav rau kev kho txoj kev pothole thiab kev siv lub tsho foob. Ob qho xwm txheej tsim cov kev cai nruj rau qhov nrawm tawg, kev sib xyaw ruaj khov thiab lub zog thaum ntxov ntawm emulsified asphalt. Tau lees paub hauv ntau qhov project, QXME 87 ua haujlwm tau zoo hauv qab cov xwm txheej ua haujlwm no.
Lub hom phiaj tseem ceeb ntawm kev tsim kho txoj kev yog kom ntev lub neej kev pabcuam ntawm txoj kev thiab txo cov nqi kho tag nrho lub neej. Cov tshuaj emulsifiers zoo tsis yog cov khoom siv raw rau kev tsim cov asphalt emulsified xwb, tab sis kuj yog cov hauv paus tseem ceeb ntawm kev daws teeb meem tag nrho. Thaum muab cov khoom QXME 87, Shanghai Qixuan Chemical muab cov pob khoom pabcuam kev txawj ntse, suav nrog kev taw qhia txog kev tsim cov qauv, kev ua kom zoo dua qub thiab kev txhawb nqa kev tsim kho hauv tsev. Txij li kev sim emulsification hauv chav kuaj thiab kev tsim khoom sim ntawm cov kab tsim khoom mus rau kev ua raws li kev txawj ntse ntawm cov chaw tsim kho, peb pab cov neeg siv khoom tsim cov asphalt emulsified tsim nyog thiab xa cov haujlwm kho txoj kev zoo.
Vim muaj kev txhim kho tas mus li rau kev thauj mus los hauv Suav teb, qhov kev thov rau cov khoom siv asphalt emulsifying uas ua tau zoo, ruaj khov hauv kev lag luam kev tiv thaiv kev taug kev tseem nce ntxiv. Nrog rau cov khoom zoo ruaj khov, kev hloov pauv dav dav thiab cov ntaub ntawv pov thawj engineering, QXME 87 cationic asphalt emulsifier ua haujlwm ua qhov kev xaiv txhim khu kev qha rau micro-surfacing thiab cationic quick-set emulsified asphalt projects, pab txhawb kev txhim kho zoo thiab kev ua haujlwm tau zoo hauv kev kho txoj kev hauv tsev thiab tiv thaiv kev nyab xeeb ntawm txoj kev loj.
