Emkhakheni wokulungiswa kokuvimbela umgwaqo omkhulu,ukufakelwa kwe-micro-surfacekanye ne-cationici-asphalt ehlanganisiwe ngokusheshaimelela ubuchwepheshe bokuvuselela umgwaqo obusezingeni eliphansi obusungulwe kahle kakhulu. Njengengxenye eyinhloko yokusebenza ngaphakathi kohlelo lwe-asphalt oluhlanganisiwe, ama-emulsifier alawula ngqo ukuzinza kokugcinwa kwe-emulsion, ukunamathelana phakathi kwe-asphalt nama-aggregates, ukusebenza kokuxuba kwezingxube, kanye nesikhathi esidingekayo ukuze umgwaqo uvulekele ithrafikhi ngemva kokwakhiwa. Amaphrojekthi emigwaqo eShayina abhekene nenselele ngenxa ye-lithology ehlukahlukene ye-aggregate, ukushintshashintsha okukhulu kwesimo sezulu sesifunda, kanye namashejuli okwakha aqinile. I-emulsifier ye-asphalt ye-cationic enokuhambisana okubanzi kwe-aggregate kanye nokusebenza okuzinzile okulawulwayo kubalulekile ekuqinisekiseni ikhwalithi yokugcinwa komgwaqo kanye nokunciphisa izingozi zokwakha endaweni.
I-Shanghai Qixuan Chemical ibilokhu igxile ezintweni ezintsha zamakhemikhali zobunjiniyela bemigwaqo. I-QXME 87 cationic asphalt emulsifier iwumkhiqizo ovuthiwe oqinisekiswe ngokuhlolwa okubanzi kwelebhu kanye nezinhlelo eziningi zobunjiniyela bensimu. Yakhelwe ngqo izinhlelo ze-cationic quick-set (CQS) emulsified asphalt kanye ne-micro-surfacing, okunikeza izixazululo ze-emulsification ezithembekile zamaphrojekthi okulungisa imigwaqo yasekhaya.
I-QXME 87 iyi-emulsifier ye-asphalt cationic esekelwe ku-amine enenani eliphansi le-amine elingu-370. Izingxenye eziningi ze-amine ezisebenzayo zinikeza umkhiqizo amandla avelele okuhlanganisa kanye namandla okushaja, okuvumela ukuhlanganiswa okuphumelelayo kwe-asphalt eyisisekelo ngaphansi kwezimo ze-asidi. Umkhiqizo uketshezi olunsundu, olunobuningi obusukela ku-0.97 kuya ku-1.05 g/cm³ eneminyaka engu-25°C. Igcina uketshezi oluhle ekushiseni okuzungezile futhi ilungele ukondla ngaphandle kokushisa nokuncibilikisa kusengaphambili. Ihambisana nemigqa yokukhiqiza i-asphalt e-batch-type kanye ne-emulsified eqhubekayo eShayina yokudlulisa izinto, ukulinganisa kanye nezinqubo zokuxuba. Inezakhiwo ezizinzile ze-physicochemical, imelana nokuhlukaniswa kanye nemvula ngaphansi kwezimo ezijwayelekile zokugcina, ikhuthaza ukuphathwa kwezindawo zokugcina impahla zabakhiqizi. Inciphisa ngempumelelo ukuguquguquka kwekhwalithi ye-emulsion okubangelwa ukushintshashintsha kokudla futhi iqinisekisa ukusebenza okuqhubekayo kwe-asphalt e-emulsified kusuka ku-batch kuya ku-batch.
Izuza esakhiweni sayo sama-molecule esiklanywe ngokukhethekile, i-asphalt emulsified eyenziwe nge-QXME 87 inezinzuzo eziningi zokusebenza ezivelele.
Okokuqala, kufinyelela ukuhambisana okuhle kakhulu kwe-emulsion-to-aggregate futhi kuhambisana nama-aggregate e-lithologies ahlukahlukene kanye nezakhiwo ze-acid-base. Ama-aggregate atholakala kumaphrojekthi emigwaqo yasekhaya ayahlukahluka kakhulu ekwakhiweni kwamakhemikhali angaphezulu, okuqukethwe yi-silt kanye nokuhlanzeka. Ama-emulsifier amaningi avame ukuhlushwa amazinga okuphuka angalawuleki kanye nokugqoka kwe-asphalt okungalingani lapho i-aggregate feedstock ishintsha. Uhlelo lwe-emulsification lwe-QXME 87 lubonisa ukubekezelela okuphezulu kwama-aggregate ahlukene. Amaconsi e-asphalt ahlanganisiwe angakha ngokushesha amafilimu e-asphalt afanayo futhi aminyene ezindaweni ezihlanganisiwe, okuthuthukisa ukunamathelana phakathi kwe-asphalt netshe. Kunciphisa kakhulu ukwehluleka kokwakhiwa okubangelwa ukushintshashintsha kwezinto zokusetshenziswa ezihlanganisiwe futhi kunciphisa amathuba okulungiswa kabusha kwephrojekthi.
Okwesibili, ingxube iletha ukusebenza okuhle kokuxuba kanye nokusebenza okwanelisayo kwe-slurry. Ngesikhathi sokuxuba izingxube ze-slurry ezincane, izinga lokuphuka kwesistimu lingalawulwa kahle. Ingxube ye-slurry igcina ifasitela elifanele lokusebenza ukuqinisekisa ukusebenza okubushelelezi kwe-pavement, ukugwema ukuhlangana nokuqhekeka ngaphambi kwesikhathi, nokuqinisekisa ukuthi i-pavement ithambile ngemva kokubekwa.
Okwesithathu, ihlangabezana nezidingo zobunjiniyela zokuvulwa kwethrafikhi ngokushesha. Ukusetshenziswa kwe-asphalt ene-micro-surface kanye ne-fast-set emulsified ngokuvamile kudinga ukuthi umgwaqo uvuleke kabusha ukuze usetshenziswe ngokushesha ngemva kokwakhiwa, kufinyezwe izikhathi zokulawula ithrafikhi futhi kuncishiswe umthelela womsebenzi womgwaqo emotweni yesifunda kanye nempilo yansuku zonke yezakhamuzi ezisendleleni. I-asphalt ene-emulsified elungiselelwe nge-QXME 87 iyaphuka futhi iphole ngesivinini esiklanyelwe ngemva kokugandaywa. Umgwaqo owenziwe uthola amandla ngokushesha futhi uhlangabezana nezimfuneko ezidingekayo zokuvulwa kabusha kwethrafikhi ngokushesha.
Okwesine, i-asphalt eqediwe emulsified ibonisa ukuzinza okuhle kakhulu kokugcina. I-emulsion ekhiqiziwe imelana nokuhlukaniswa kwezigaba kanye nokuhlukaniswa phakathi nesikhathi esibekiwe sokugcina, yandisa isikhathi sokugcina kanye nokuthutha ama-emulsion aqediwe. Iphinde inciphise imfucuza yezinto ezibonakalayo kanye nezingozi zobunjiniyela ezivela ekuhlulekeni kwe-emulsion ngaphambi kwesikhathi.
Ngokusekelwe ezivivinyweni zokwakheka kwesikhathi eside kanye nokubuyekezwa kwamaphrojekthi asensimini, amafomula amabili okubhekisela avuthiwe e-QXME 87 afingqiwe ngezansi. I-pH yazo zombili izinhlelo ilungiswa ibe yi-1.5–2.5 ene-hydrochloric acid, ukuze kubhekwe kuyo ekulungiseleleni amasampula elebhu kanye nokukhiqizwa kwezimboni.

I-Latex iyisici esiyimpoqo ezinhlelweni ze-micro-surfacing ukuze kuthuthukiswe ukumelana nokuguguleka kanye nokumelana nokuqhekeka kwesendlalelo se-slurry seal esilungisiwe. Le ndlela ifanelekela ukulungiswa kwe-micro-surfacing yokuvimbela emigwaqweni emikhulu yezinga eliphezulu kanye nemigwaqo yasedolobheni. Zombili lezi zindlela zilula ukuzisebenzisa emigqeni yokukhiqiza i-asphalt ehlanganisiwe evamile. Amakhasimende angalungisa kahle isilinganiso se-emulsifier kanye ne-formula ratios ngokusekelwa kobuchwepheshe okuvela eShanghai Qixuan Chemical, ehambisana nezidingo zephrojekthi ezenziwe ngokwezifiso ngokusekelwe kumabanga e-asphalt akhethiwe, izakhiwo ezihlanganisiwe kanye nemininingwane yobuchwepheshe.
Ngokuphathelene nezimo zokusetshenziswa kobunjiniyela, i-QXME 87 iyasebenza emisebenzini yokulungisa izithiyo kanye nokulungisa izitimela eziphuthumayo emigwaqweni emikhulu, emigwaqweni emikhulu kazwelonke neyesifundazwe, kanye nemigwaqo kamasipala. Njengesixazululo sokulungisa esinezingqimba ezincane esinejubane lokwakha elisheshayo, izindleko ezimaphakathi, ukuvimbela amanzi kanye nokumelana nokuguguleka, i-micro-surfacing ubuchwepheshe obukhethwayo bokwelapha amaphutha ezitimela ezisesigabeni sokuqala. I-asphalt emulsified quick-set Cationic isetshenziswa kabanzi ekulungiseni imigodi yetimela kanye nezicelo ze-seal coat. Zombili lezi zimo zibeka izidingo eziqinile esilinganisweni sokuphuka, ukuxuba ukuzinza kanye namandla okuqala e-asphalt emulsified. Iqinisekiswe kumaphrojekthi amaningi, i-QXME 87 isebenza ngokuthembeka ngaphansi kwalezi zimo zokusebenza.
Inhloso eyinhloko yobunjiniyela bokulungiswa kwemigwaqo ukwandisa impilo yesevisi yabahamba ngezinyawo nokunciphisa izindleko zokulungisa umjikelezo wempilo yonke. Ama-emulsifier asezingeni eliphezulu awawona nje kuphela izinto zokusetshenziswa zokukhiqizwa kwe-asphalt e-emulsified, kodwa futhi ayizinsika zobuchwepheshe zesisombululo sonke sokulungisa. Ngenkathi ihlinzeka ngemikhiqizo ye-QXME 87, i-Shanghai Qixuan Chemical inikeza iphakheji yesevisi yobuchwepheshe ephelele, okuhlanganisa isiqondiso sokulungisa iphutha lokwakheka, ukwenza ngcono inqubo yokukhiqiza kanye nokusekelwa kobuchwepheshe bokwakha endaweni. Kusukela ekuhlolweni kwe-emulsification kwelebhu kanye nokukhiqizwa kokuhlola emigqeni yokukhiqiza kuya ekulandeleni kobuchwepheshe ezindaweni zokwakha, sisiza amakhasimende ukuthi akhiqize i-asphalt e-emulsified efanelekile futhi alethe ngempumelelo amaphrojekthi okulungiswa kwemigwaqo.
Naphezu kokuthuthukiswa okuqhubekayo kokulungiswa kwengqalasizinda yezokuthutha eShayina, isidingo sezinto zokwakha i-asphalt ezisebenza kahle nezizinzile emakethe yokulungisa imigwaqo yokuvimbela siyaqhubeka nokukhula. Ngekhwalithi yomkhiqizo ezinzile, ukuzivumelanisa nezimo okubanzi kanye namarekhodi obunjiniyela aqinisekisiwe, i-QXME 87 asphalt emulsifier esebenza njengenketho ethembekile yamaphrojekthi e-asphalt e-emulsified asphalt asebenza kahle kakhulu kanye ne-cationic esheshayo, okwenza kube lula ukuthuthukiswa kwekhwalithi kanye nokuzuza kokusebenza kahle ekunakekelweni kwemigwaqo yasekhaya kanye nokuvikela ukuphepha kwemigwaqo emikhulu.
