Kupfapfaidza inokurumidza-kugadzika rubber asphalt isina mvura yekuputira ndeyemvura-yakavakirwa coating. Kana iyo diaphragm isina kunyatso chengetwa mushure mekupfapfaidza, mvura haizonyunguduke zvachose, uye mhepo yakakora inooneka nyore panguva yekupisa-kupisa, zvichikonzera kutetepa kwefirimu rekudzivirira mvura, uye kusapinda mvura, anti-corrosion, uye kusagadzikana kwemamiriro ekunze. . Nekuda kwekuti mamiriro ekugadzirisa enzvimbo panzvimbo yekuvaka anowanzo kusadzoreka, zvakakosha kuvandudza tembiricha yakakwira yekupfapfaidza inokurumidza-kugadzika rubber asphalt isina mvura machira kubva pamaonero ekugadzira.
Mvura-soluble cellulose ether yakasarudzwa kuti ivandudze kupisa kwekushisa kwepamusoro-soro yakapfapfaidzwa inokurumidza-kugadzika rubber asphalt yekudzivirira mvura. Panguva imwecheteyo, migumisiro yemhando uye chiyero che cellulose ether pamagetsi emagetsi, kupfapfaidza kushanda, kupisa kupisa uye kuchengetedza kwekuputira nokukurumidza-kugadza rubber asphalt mvura isina mvura yakadzidzwa. performance impact.
Kugadzirira kwemuenzaniso
Dissolve hydroxyethyl cellulose mu 1/2 deionized mvura, kurunga kusvika yanyungudika zvachose, wobva wawedzera emulsifier uye sodium hydroxide kune yasara 1/2 mvura yakasvibiswa uye simbisa zvakaenzana kugadzirira sipo mhinduro, uye pakupedzisira, sanganisa zviri pamusoro. zvakaenzana zvakasanganiswa kuwana aqueous solution yehydroxyethyl cellulose, uye kukosha kwayo pH kunodzorwa pakati pe11 ne13.
Sanganisa emulsified asphalt, neoprene latex, hydroxyethyl cellulose aqueous solution, defoamer, zvichingodaro maererano neimwe reshiyo kuti uwane zvinhu A.
Gadzirira imwe kuungana kweCa(NO3)2 aqueous solution seB zvinhu.
Shandisa yakakosha yemagetsi yekupfapfaidza midziyo yekupfapfaidza zvinhu A uye zvinhu B pabepa rekuburitsa panguva imwe chete, kuitira kuti zvinhu zviviri izvi zvigone kubatwa uye nekukasira kuiswa mufirimu panguva yekuyambuka atomization process.
Migumisiro uye nhaurirano
Hydroxyethyl cellulose ine viscosity ye10 000 mPa·s uye 50 000 mPa · s yakasarudzwa, uye nzira yekuwedzera-yakagamuchirwa kuti iongorore mhedzisiro yeviscosity uye kuwedzera huwandu hwehydroxyethyl cellulose pakupfapfaidza kuita kwekukurumidza-kuseta. rubber asphalt waterproof coatings, Film-forming properties, heat resistance, mechanical properties uye kuchengetedza zvinhu. Kuti udzivise kukuvadzwa kweiyo system balance inokonzerwa nekuwedzerwa kweiyo hydroxyethyl cellulose mhinduro, zvichikonzera demulsification, emulsifier uye pH regulator yakawedzerwa panguva yekugadzirira kweiyo hydroxyethyl cellulose mhinduro.
Kupesvedzera kweViscosity yeHydroxyethyl Cellulose (HEC) paKupfapfaidza uye Firimu-Kugadzira Zvivakwa zveMavhare asina Mvura.
Iyo yakakura viscosity yehydroxyethyl cellulose (HEC), iyo yakakura kukanganisa pakupfapfaidza uye firimu-kuumba zvimiro zvemachira asingapindi mvura. Kana kuwedzera kwayo kuri 1 ‰, HEC ine viscosity ye 50 000 mPa·s inoita viscosity yemvura inoputira system Kana ichiwedzerwa ne10 nguva, spraying inova yakaoma zvikuru, uye diaphragm inoderera zvakanyanya, nepo HEC ine viscosity. zve10 000 mPa·s hazvina zvazvinoita pakupfapfaidza, uye diaphragm inodzikira zvakajairika.
Mhedzisiro yeHydroxyethyl Cellulose (HEC) paKupisa Kupokana kweMapaka Asingapindi Mvura
Iyo yakapfapfaidzwa inokurumidza-kugadzika rabha asphalt isina mvura yekuputira yakapfapfaidzwa papepa realuminium kuti igadzirire kupisa kupisa bvunzo sampu, uye yakarapwa zvinoenderana nemamiriro ekurapa emvura-based asphalt isina mvura yekuputira yakatsanangurwa muyero yenyika GB/T 16777- 2008. Iyo hydroxyethyl cellulose ine viscosity ye50 000 mPa·s ine huremu hwakati kurei. Mukuwedzera kune kunonoka kubuda kwemvura, inewo imwe nzira yekusimbisa, zvichiita kuti zvive zvakaoma kuti mvura ibudise kubva mukati mekuputira, saka inobudisa mabhuru makuru. Iyo molecular huremu hwehydroxyethyl cellulose ine viscosity ye10 000 mPa · s idiki, iyo ine zvishoma zvishoma pane simba rezvinhu uye haina kukanganisa kuvhuvhuta kwemvura, saka hapana bubble chizvarwa.
Mhedzisiro yehuwandu hwehydroxyethyl cellulose (HEC) yakawedzerwa
Hydroxyethyl cellulose (HEC) ine viscosity ye10 000 mPa·s yakasarudzwa sechinhu chekutsvakurudza, uye zvinokonzerwa nekuwedzera kwakasiyana kweHEC pakushanda kwekupfapfaidza uye kupisa kwekudzivirira kwekuvhara mvura kwakaongororwa. Tichifunga nezvekuita kwekupfapfaidza, kupisa kwekudzivirira uye michina yezvipfeko zvekuvhara mvura zvakakwana, inofungidzirwa kuti iyo yakakwana yekuwedzera huwandu hwehydroxyethyl cellulose ndeye 1 ‰.
Iyo neoprene latex mune yakapfapfaidzwa inokurumidza-kugadzika rabha asphalt isina mvura yekuputira uye emulsified asphalt ine mutsauko wakakura mu polarity uye density, izvo zvinotungamira ku delamination yechinhu A munguva pfupi yenguva panguva yekuchengetedza. Naizvozvo, panguva yekuvaka-panzvimbo Inoda kubvongodzwa zvakaenzana isati yapfapfaidzwa, kana zvisina kudaro inozotungamira kune njodzi dzemhando. Hydroxyethyl cellulose inogona kunyatso kugadzirisa dambudziko re delamination rekupfapfaidza nekukurumidza-kuseta rabha asphalt isina mvura yekupfeka. Mushure memwedzi mumwe chete wekuchengetedza, hapachina delamination. Iyo viscosity yehurongwa haina kuchinja zvakanyanya, uye kugadzikana kwakanaka.
focus
1) Mushure mokunge hydroxyethyl cellulose yawedzerwa kune yakapfapfaidzwa inokurumidza-kugadzika rubber asphalt isina mvura yekuputira, kupisa kwekudzivirira kwekuvhara kwemvura kunovandudzwa zvikuru, uye dambudziko remabhubhu akaomeswa pamusoro pekuvhara rinovandudzwa zvikuru.
2) Pasi pechikonzero chekusakanganisa kushandiswa kwekupfira, firimu-kuumba kushanda uye zvinhu zvekugadzirisa zvinhu, iyo hydroxyethyl cellulose yakatsunga kuva hydroxyethyl cellulose ine viscosity ye10 000 mPa · s, uye kuwedzera kwekuwedzera kwaiva 1 ‰.
3) Kuwedzerwa kwehydroxyethyl cellulose kunovandudza kugadzikana kwekuchengetedza kweakapfapfaidzwa nekukurumidza-kuseta rabha asphalt isina mvura yekuputira, uye hapana delamination inoitika mushure mekuchengetwa kwemwedzi mumwe.
