I roto i te mara o te tiaki ārai huarahi,papa-itime te kationikauku tere-whakarewae tohu ana i ngā hangarau whakaora paparanga angiangi kua tino whakapumautia. Hei wāhanga matua o te pūnaha uku kua whakakāhia, ka whakahaere tika ngā whakakāhia i te pumau o te rokiroki whakakāhia, te piri o te mata i waenga i te uku me ngā konganuku, te mahi whakaranu o ngā ranunga, me te wā e hiahiatia ana kia tuwhera te papa ki ngā waka i muri i te hanganga. E werohia ana ngā kaupapa rori i Haina e ngā momo hanganga konganuku, ngā rerekētanga āhuarangi ā-rohe nui, me ngā wā hanga poto. He mea nui te whakakāhia uku cationic me te hototahi whānui o te konganuku me te mahi pumau ka taea te whakahaere hei whakapūmau i te kounga tiaki rori me te whakaiti i ngā mōrearea hanga i runga i te papa.
Kua roa a Shanghai Qixuan Chemical e aro nui ana ki ngā rauemi matū hou mō te hangarau rori. Ko te QXME 87 cationic asphalt emulsifier he hua pakari kua whakamanahia mā roto i ngā whakamātautau hanganga taiwhanga whānui me ngā tono hangarau mara maha. He mea hanga motuhake mō ngā pūnaha ara me ngā pūnaha papa-iti kua whakaemihia ki te cationic quick-set (CQS), e whakarato ana i ngā otinga whakaemi pono mō ngā kaupapa tiaki rori ārai-ā-whare.
He emulsifier uku cationic te QXME 87, he amine-based, ko tōna uara amine iti rawa ko te 370. Nā te nui o ngā wāhanga amine hohe, ka tino pai te kaha o te emulsifying me te kaha utu, ka taea ai te emulsification pai o te uku turanga i raro i ngā āhuatanga waikawa. He wai parauri te hua, me te mātotoru mai i te 0.97 ki te 1.05 g/cm³ i te 25°C. Ka mau tonu te rere pai i te pāmahana taiao, ā, he watea hoki mō te whāngai me te kore e whakamahanatia, e whakarewaina rānei. He hototahi ki ngā raina whakaputa uku whakapūmau me ngā raina whakaputa uku whakapūmau tonu i Haina mō te kawe rauemi, te ine me te whakaranu. He āhuatanga ā-tinana, ā-matū pumau, ā, ka ātete ki te wehewehenga me te ua i raro i ngā tikanga rokiroki noa, ka āwhina i te whakahaere whare putunga mō ngā kaihanga. Ka whakaitihia te kounga whakapūmau e te rerekētanga whāngai, ā, ka whakarite kia rite te mahi a te uku whakapūmau mai i te puranga ki te puranga.
He maha ngā painga nui o te hanganga ngota i hangaia mō te uku kua whakaemuhia ki te QXME 87, nā te mea he motuhake tōna hoahoa.
Tuatahi, ka tutuki i a ia te hototahitanga pai rawa atu i waenga i te emulsion me te aggregate, ā, ka uru ki ngā aggregate o ngā momo lithology me ngā āhuatanga waikawa-base. He rerekē te hanganga matū o ngā aggregate i ahu mai i ngā kaupapa rori ā-whare, te nui o te paru me te ma. He maha ngā aggregate e pāngia ana e te tere pakaru kāore i te whakahaeretia me te paninga uku koretake ina huri te rauemi whāngai aggregate. He nui te manawanui o te pūnaha emulsification o QXME 87 ki ngā aggregate rerekē. Ka taea e ngā pata uku kua emulsified te hanga tere i ngā kiriata uku ōrite me te matotoru ki runga i ngā mata aggregate, ka whakapai ake i te piri i waenga i te uku me te kōhatu. Ka tino whakaiti i ngā rahunga hangahanga i puta mai i ngā rerekētanga o ngā rauemi mata aggregate, ā, ka whakaiti i te tūponotanga o te mahi anō i te kaupapa.
Tuarua, ka tukuna e te ranunga he mahi whakaranu pai me te ngāwari o te mahi a te paru. I te wā e whakaranua ana ngā ranunga paru papa-iti, ka taea te whakahaere pai i te tere pakaru o te pūnaha. Ka mau tonu te matapihi mahi tika o te ranunga paru hei whakarite kia maeneene ngā mahi whakatakoto papa, kia kore ai e kohikohi wawe me te whakakorikori, me te whakarite kia papatahi te papa i muri i te whakatakotoranga.
Tuatoru, e tutuki ana i a ia ngā whakaritenga hangarau mō te whakatuwheratanga tere o ngā waka. Ko ngā tono uku whakapūmau moroiti me te uku tere-whakatakoto me whakatuwhera anō te huarahi ki ngā waka i muri tata mai i te hanganga, ka whakapoto i ngā wā whakahaere waka me te whakaiti i te pānga o ngā mahi rori ki ngā waka ā-rohe me te oranga o ia rā o ngā kainoho i te huarahi. Ko te uku whakapūmau i whakaritea ki te QXME 87 ka pakaru me te whakamaroke i te tere kua hoahoatia i muri i te whakapūmau. Ka tere te kaha o te ara kua hangaia, ā, ka tutuki i ngā whakaritenga e hiahiatia ana mō te whakatuwheratanga tere o ngā waka.
Tuawhā, he tino pai te pumau o te arai kua oti te whakapūkara. Ka ātete te whakapūkara kua puta ki te wehewehe me te whakarōpūtanga i roto i te wā rokiroki kua tohua, ka roa ake te wā rokiroki me te kawe mō ngā whakapūkara kua oti. Ka whakaitihia hoki e ia ngā para rauemi me ngā tūponotanga hangarau e puta mai ana i te pakaru wawe o te whakapūkara.
I runga i ngā whakamātautau whakatakotoranga roa me ngā arotake o ngā kaupapa mara, e rua ngā whakatakotoranga tohutoro pakeke mō QXME 87 kua whakarāpopototia i raro nei. Kua whakatikatikaina te pH o ngā pūnaha e rua ki te 1.5.–2.5 me te waikawa hauwaiora, hei tohutoro i roto i te whakarite tauira taiwhanga me te whakaputa ahumahi.

Mō ngā āhuatanga tono hangarau, ka taea te whakamahi i te QXME 87 mō ngā mahi tiaki ārai me ngā mahi whakatika whariki ohorere i runga i ngā huarahi tere, ngā huarahi nui ā-motu me ngā huarahi porowini, me ngā rori ā-tāone. Hei otinga tiaki paparanga angiangi me te tere hanga tere, te utu taurite, te ātete ā-wai me te ātete kakahu, ko te papa-iti te hangarau pai mō te rongoā i ngā hapa whariki tīmatanga. E whakamahia whānuitia ana te uku whakarewa tere-kationika mō te whakatika poka whariki me te tono paninga hiri. E rua ngā āhuatanga e whakatakoto ana i ngā whakaritenga tino kaha mō te tere pakaru, te pumau o te ranunga me te kaha wawe o te uku whakarewa. Kua whakamanahia i roto i ngā kaupapa maha, ka pono te mahi a te QXME 87 i raro i ēnei tikanga mahi.
Ko te whāinga matua o te hangarau tiaki rori he whakaroa i te roa o te ratonga papa me te whakaiti i te utu tiaki i te huringa ora katoa. Ehara i te mea ko ngā emulsifier kounga teitei he rauemi mata mō te hanga uku whakarewa anake, engari he pou hangarau hoki mō te otinga tiaki katoa. I a mātou e whakarato ana i ngā hua QXME 87, ka whakaratohia e Shanghai Qixuan Chemical he kete ratonga hangarau whānui, tae atu ki te aratohu whakatikatika whakatakotoranga, te arotau tukanga whakaputa me te tautoko hangarau hanga i te papa. Mai i ngā whakamātautau emulsification tauine taiwhanga me te whakaputa whakamātautau i runga i ngā raina hanga ki te whai i ngā hangarau i ngā papa hanga, ka āwhina mātou i ngā kiritaki ki te whakaputa pumau i te uku whakarewa whai tohu me te tuku tika i ngā kaupapa tiaki rori.
I roto i te horopaki o te whakapai tonu i ngā hanganga kawe waka i Haina, kei te piki haere tonu te hiahia mō ngā rauemi whakapūmau uku teitei, pumau i roto i te mākete tiaki ara ārai. Mā te kounga hua pumau, te urutau whānui me ngā rekoata hangarau kua whakamātauhia, ka mahi te whakapūmau uku cationic QXME 87 hei kōwhiringa pono mō ngā kaupapa papa-iti me ngā kaupapa uku whakapūmau cationic, e āwhina ana i te whakapai ake i te kounga me te whai huatanga i roto i te tiaki rori ā-whare me te tiaki i te haumaru o te huarahi tere.
