Kwicandelo lokugcinwa kwendlela yokuthintela umngcipheko,umphezulu omncincikunye ne-cationici-asphalt exutyiweyo ebekwe ngokukhawulezaZimela ezona teknoloji zokuvuselela indlela ezisemgangathweni ezisemgangathweni. Njengenxalenye ephambili yokusebenza kwinkqubo ye-asphalt ehlanganisiweyo, ii-emulsifiers zilawula ngokuthe ngqo uzinzo lokugcina i-emulsion, ukunamathelana phakathi kwe-asphalt kunye nee-aggregates, ukusebenza kokuxubana kwemixube, kunye nexesha elifunekayo ukuze indlela ivulekele izithuthi emva kokwakhiwa. Iiprojekthi zeendlela eTshayina zijongene nemingeni eyahlukeneyo ye-aggregate lithology, utshintsho olukhulu lwemozulu yengingqi, kunye neeshedyuli zokwakha ezixineneyo. I-cationic asphalt emulsifier enokuhambelana okubanzi kunye nokusebenza okuzinzileyo okulawulwayo kubalulekile ekuqinisekiseni umgangatho wokugcinwa kwendlela kunye nokunciphisa umngcipheko wokwakha kwindawo.
IShanghai Qixuan Chemical ibisoloko igxile kwizixhobo ezintsha zeekhemikhali zobunjineli beendlela. I-QXME 87 cationic asphalt emulsifier yimveliso evuthiweyo eqinisekiswe ngovavanyo olubanzi lwelebhu kunye nezicelo ezininzi zobunjineli bentsimi. Yenzelwe ngokukodwa iinkqubo ze-cationic quick-set (CQS) emulsified asphalt kunye ne-micro-surfacing, inikezela ngezisombululo ze-emulsification ezinokuthenjwa kwiiprojekthi zokukhusela ukugcinwa kweendlela zasekhaya.
I-QXME 87 yi-amine-based cationic asphalt emulsifier enexabiso elincinci le-amine eliyi-370. Izixhobo ze-amine ezisebenzayo ezininzi zinika imveliso amandla abalaseleyo okuxubha kunye namandla okutshaja, okuvumela ukuxubha okusebenzayo kwe-asphalt esisiseko phantsi kweemeko ze-asidi. Imveliso lulwelo olumdaka, olunobunzima obuqala kwi-0.97 ukuya kwi-1.05 g/cm³ eneminyaka engama-25°C. Igcina ukunyibilika okuhle kubushushu obuphakathi kwaye ilungele ukondla ngaphandle kokufudumeza nokunyibilikisa kwangaphambili. Ihambelana nemigca yemveliso ye-asphalt exutywe ngohlobo lwebhetshi kunye neenkqubo zokuvelisa i-asphalt eqhubekayo e-China zokuhambisa izinto, ukulinganisa kunye nokuxuba. Ineempawu ze-physicochemical ezizinzileyo, iyamelana nokuqhekeka kunye nokuna kwemvula phantsi kweemeko eziqhelekileyo zokugcina, iququzelela ulawulo lwendawo yokugcina impahla kubavelisi. Inciphisa ngokufanelekileyo ukuguquguquka komgangatho we-emulsion okubangelwa kukwahluka kokutya kwaye iqinisekisa ukusebenza rhoqo kwe-asphalt exutywe ukusuka kwibhetshi ukuya kwibhetshi.
Ixhamla kwisakhiwo sayo semolekyuli esiyilwe ngokukodwa, i-asphalt emulsified eyenziwe nge-QXME 87 ineenzuzo ezininzi zokusebenza ezibalaseleyo.
Okokuqala, ifikelela kwi-emulsion-to-aggregate ehambelana kakuhle kwaye ifanela ii-aggregates ze-lithologies ezahlukeneyo kunye neempawu ze-acid-base. Ii-aggregates ezifunyenwe kwiiprojekthi zeendlela zasekhaya ziyahluka kakhulu kwi-surface chemical composition, umxholo we-silt kunye nococeko. Ii-emulsifiers ezininzi zihlala zinengxaki yamazinga okuqhekeka angalawulekiyo kunye ne-asphalt coating engalinganiyo xa i-aggregate feedstock itshintsha. Inkqubo ye-emulsification ye-QXME 87 ibonisa ukunyamezela okuphezulu kwii-aggregates ezahlukeneyo. Ii-asphalt drops ezi-emulsified zinokwenza ngokukhawuleza iifilimu ze-asphalt ezifanayo nezixineneyo kwiindawo ezihlanganisiweyo, ziphucula ukunamathelana phakathi kwe-asphalt kunye nelitye. Inciphisa kakhulu ukusilela kokwakhiwa okubangelwa kukuguquguquka kwezinto eziluhlaza ezihlanganisiweyo kwaye inciphisa amathuba okuphinda kusetyenziswe iprojekthi.
Okwesibini, umxube unika ukusebenza okuhle kokuxuba kunye nokusebenza kakuhle kodaka. Ngexesha lokuxuba umxube wedaka okwi-micro-surfacing, izinga lokuqhekeka kwenkqubo linokulawulwa kakuhle. Umxube wedaka ugcina ifestile yokusebenza efanelekileyo ukuqinisekisa ukusebenza kakuhle kwe-paving, ukuthintela ukuhlangana kwangaphambi kwexesha kunye nokuqhekeka, kunye nokuqinisekisa ukuba i-pavement ithambile emva kokubekwa.
Okwesithathu, iyahlangabezana neemfuno zobunjineli zokuvula iimoto ngokukhawuleza. Ukusetyenziswa kwe-asphalt exutyiweyo ene-micro-surface kunye ne-emulsified equid equid ngokukhawuleza ngokubanzi kufuna ukuba indlela ivulwe kwakhona ukuze ifikelele kwiimoto emva nje kokwakhiwa, inciphisa amaxesha olawulo lwezithuthi kwaye inciphise impembelelo yomsebenzi wendlela kwiimoto zengingqi kunye nobomi bemihla ngemihla babemi abakuloo ndlela. I-asphalt exutyiweyo ene-emulsified elungiselelwe nge-QXME 87 iyaphuka kwaye iphiliswe ngesantya esicwangcisiweyo emva kokupaka. Indlela eyakhiweyo ifumana amandla kwangoko kwaye ihlangabezana neemfuno eziyimfuneko zokuvula kwakhona iimoto ngokukhawuleza.
Okwesine, i-asphalt egqityiweyo exutyiweyo ibonisa uzinzo oluhle kakhulu lokugcina. I-emulsion evelisiweyo imelana nokuhluthwa kunye nokwahlulwahlulwa phakathi kwexesha elichaziweyo lokugcina, yandisa ixesha lokugcina kunye nokuthutha ii-emulsion ezigqityiweyo. Ikwanciphisa inkunkuma yezinto kunye neengozi zobunjineli ezivela ekusileleni kwe-emulsion ngaphambi kwexesha.
Ngokusekelwe kwizilingo zokwenziwa kwexesha elide kunye nophononongo lweeprojekthi zasentsimini, iifomyula ezimbini ezivuthiweyo ze-QXME 87 zishwankathelwe ngezantsi. I-pH yazo zombini iinkqubo ihlengahlengiswa ibe yi-1.5–2.5 ene-hydrochloric acid, ukuze isetyenziswe ekulungiseleleni iisampulu zelebhu nakwimveliso yemizi-mveliso.

Le fomyula ifanelekile kulondolozo lwe-micro-surfacing olukhuselayo kwiindlela eziphakamileyo nakwiindlela zasezidolophini. Zombini ezi fomyula kulula ukuzisebenzisa kwimigca yemveliso ye-asphalt exutyiweyo eqhelekileyo. Abathengi banokuyilungisa kakuhle idosi ye-emulsifier kunye ne-formula ratios ngenkxaso yobugcisa evela kwiShanghai Qixuan Chemical, ihambelana neemfuno zeprojekthi ezenzelwe wena ngokusekelwe kumanqanaba akhethiweyo e-asphalt, iipropati ezihlanganisiweyo kunye neenkcukacha zobugcisa.
Ngokuphathelele iimeko zokusetyenziswa kobunjineli, i-QXME 87 iyasebenza kulondolozo lokuthintela kunye nemisebenzi yokulungisa iindledlana ezingxamisekileyo kwiindlela ezinkulu, kwiindlela zelizwe nezephondo, nakwiindlela zikamasipala. Njengesisombululo solondolozo esinomgangatho omncinci esinesantya sokwakha esikhawulezayo, iindleko eziphakathi, ukuthintela amanzi kunye nokumelana nokuguguleka, i-micro-surfacing yeyona teknoloji ikhethwayo yokunyanga iziphene zendlela ezikwinqanaba lokuqala. I-asphalt e-emulsified quick-set e-cationic iyasetyenziswa kakhulu ekulungiseni imingxuma yendlela kunye nokusetyenziswa kwe-seal coat. Zombini ezi meko zibeka iimfuno ezingqongqo kwisantya sokuqhekeka, ukuzinza kokuxuba kunye namandla okuqala e-asphalt e-emulsified. Iqinisekiswe kwiiprojekthi ezininzi, i-QXME 87 isebenza ngokuthembekileyo phantsi kwezi meko zokusebenza.
Injongo ephambili yobunjineli bokugcinwa kweendlela kukwandisa ubomi benkonzo yendlela kunye nokunciphisa iindleko zokugcina ubomi bonke. Ii-emulsifiers ezikumgangatho ophezulu azizo nje izinto zokwenza imveliso ye-asphalt exutyiweyo, kodwa zikwayiziseko zobugcisa zesisombululo sokugcinwa sonke. Ngelixa sinikezela ngeemveliso ze-QXME 87, iShanghai Qixuan Chemical ibonelela ngephakheji yenkonzo yobugcisa ebanzi, kubandakanya isikhokelo sokulungisa iimpazamo zefomula, ukwenziwa ngcono kwenkqubo yemveliso kunye nenkxaso yobugcisa yokwakha kwindawo. Ukusuka kwizilingo ze-emulsification zelebhu kunye nemveliso yovavanyo kwimigca yokuvelisa ukuya kulandelelo lobuchwephesha kwiindawo zokwakha, sinceda abathengi ukuba bavelise i-asphalt exutyiweyo efanelekileyo kwaye banikezele ngempumelelo iiprojekthi zokugcinwa kweendlela.
Ngokuchasene nokuphuculwa okuqhubekayo kokugcinwa kweziseko zothutho eTshayina, imfuno yezinto ezivelisa i-asphalt ezisebenza kakuhle nezizinzileyo kwimarike yokugcinwa kwendlela yokuthintela iyaqhubeka nokukhula. Ngomgangatho wemveliso ozinzileyo, ukuguquguquka ngokubanzi kunye neerekhodi zobunjineli eziqinisekisiweyo, i-QXME 87 asphalt emulsifier ye-cationic isebenza njengokhetho oluthembekileyo kwiiprojekthi ze-asphalt ezivelisa i-asphalt ezikhawulezayo kunye ne-cationic, okwenza kube lula ukuphucula umgangatho kunye nokuzuza ngokufanelekileyo ekugcinweni kweendlela zasekhaya kunye nokukhusela ukhuseleko lwezithuthi zendlela.
