Kupfapfaidza jira rinopinda mvura neasphalt rabha rinoiswa nekukurumidza kuvharwa kwakavakirwa mumvura. Kana diaphragm isina kuchengetwa zvizere mushure mekupfapfaidza, mvura haizopwa zvachose, uye mabhubhu emhepo akasimba anoonekwa zviri nyore panguva yekubika pakupisa kwakanyanya, zvichikonzera kutetepa kwefirimu risingapindi mvura, uye kusagadzikana kwemvura, kudzivirira ngura, uye mamiriro ekunze. . Nekuti mamiriro ekuchengetedza panzvimbo yekuvaka anowanzo kuve asingadzoreki, zvakakosha kuvandudza kudzivirira kupisa kwakanyanya kwejira rinopinda mvura neasphalt rabha rinoiswa nekukurumidza kubva pamaonero ekugadzira.
Ether yerubha inonyungudika mumvura yakasarudzwa kuti ivandudze kusimba kwekupisa kwakanyanya kwezvinhu zvinopfapfaidzwa zvinodzivirira mvura zverabha asphalt zvinokurumidza kuiswa. Panguva imwe chete, mhedzisiro yerudzi nehuwandu hwe ether yerubha cellulose pahunhu hwemakanika, mashandiro ekupfapfaidza, kusimba kwekupisa uye kuchengetwa kwezvipfeko zvinodzivirira mvura zverabha asphalt zvinokurumidza kuiswa zvakadzidzwa.
Kugadzirira muenzaniso
Nyungudutsa hydroxyethyl cellulose muhafu yemvura yakasanganiswa, kurunga kusvika yanyungudika zvachose, wobva wawedzera emulsifier nesodium hydroxide kuhafu yemvura yakasanganiswa wokurunga zvakaenzana kugadzira sipo, uye pakupedzisira, sanganisa zviri pamusoro apa. Mhinduro mbiri idzi dzakasanganiswa zvakaenzana kuti pave ne hydroxyethyl cellulose ine mvura, uye pH yayo inodzorwa pakati pe11 ne13.
Sanganisa asphalt yakasanganiswa, neoprene latex, hydroxyethyl cellulose aqueous solution, defoamer, nezvimwewo zvichienderana nechiyero chakati chekuwana zvinhu A.
Gadzirira huwandu hwakati hweCa(NO3)2 mvura inobuda semushonga weB.
Shandisa michina yekupfapfaidza yemagetsi yakakosha kupfapfaidza zvinhu A neB papepa rekuburitsa panguva imwe chete, kuitira kuti zvinhu zviviri izvi zvigone kubatwa uye kupinza firimu nekukurumidza panguva yekubatanidza atomization.
Mhedzisiro nehurukuro
Hydroxyethyl cellulose ine viscosity ye10 000 mPa·s uye 50 000 mPa·s yakasarudzwa, uye nzira yekuwedzera mushure mekuwedzera yakatorwa kuti iongorore mhedzisiro ye viscosity uye huwandu hwekuwedzera kwehydroxyethyl cellulose pakushanda kwekupfapfaidza kwerabha asphalt inogadziriswa nekukurumidza, hunhu hwekugadzira mafirimu, kuramba kupisa, hunhu hwemakanika uye hunhu hwekuchengetedza. Kuti tidzivise kukuvara kwehurongwa hwakakonzerwa nekuwedzerwa kwe hydroxyethyl cellulose solution, zvichikonzera demulsification, emulsifier uye pH regulator zvakawedzerwa panguva yekugadzirira hydroxyethyl cellulose solution.
Kukanganisa kweHydroxyethyl Cellulose (HEC) pakupfapfaidza uye kugadzira mafirimu ezvipfeko zvisingapindi mvura
Kana viscosity yehydroxyethyl cellulose (HEC) (HEC) yakakura, ndipo panonyanya kukanganisa mashandiro ekupfapfaidza nekugadzira firimu ezvipfeko zvisingapindi mvura. Kana huwandu hwayo hwekuwedzera huri 1‰, HEC ine viscosity ye50 000 mPa·s inoita kuti viscosity yesystem yekupfapfaidza isingapindi mvura iwedzere. Kana yakawedzerwa kagumi, kupfapfaidza kunova kwakaoma zvikuru, uye diaphragm inodzikira zvakanyanya, nepo HEC ine viscosity ye10 000 mPa·s isina simba guru pakupfapfaidza, uye diaphragm inodzikira zvakajairika.
Mhedzisiro yeHydroxyethyl Cellulose (HEC) paKuramba Kupisa kweMachira Asingapindi Mvura
Kuputira mvura kwerabha asphalt kwakapfapfaidzwa nekukurumidza kwakapfapfaidzwa papepa rearuminiyamu kugadzirira muenzaniso wekuyedza wekudzivirira kupisa, uye kwakapfapfaidzwa zvichienderana nemamiriro ekupisa kwepurasitiki yeasphalt isina mvura yakatorwa mumvura yakatarwa mu standard GB/T 16777-2008 yenyika. Hyxyethyl cellulose ine viscosity ye50 000 mPa·s ine huremu hwakawanda hwemamorekuru. Kuwedzera pakunonotsa kupwanya kwemvura, inewo simba rekusimbisa, zvichiita kuti zviomere mvura kupwanya kubva mukati mepurasitiki, saka ichaburitsa mabundu makuru. Huremu hwemamorekuru hwehydroxyethyl cellulose ine viscosity ye10 000 mPa·s idiki, iyo haina simba guru pakusimba kwechinhu uye haikanganisi kupwanya kwemvura, saka hapana kugadzirwa kwemabubble.
Mhedzisiro yehuwandu hwehydroxyethyl cellulose (HEC) yakawedzerwa
Hydroxyethyl cellulose (HEC) ine viscosity ye10 000 mPa·s yakasarudzwa sechinangwa chekutsvagisa, uye mhedzisiro yekuwedzera kwakasiyana kweHEC pakushanda kwekupfapfaidza uye kuramba kupisa kwezvipfeko zvisingapindi mvura zvakaongororwa. Tichifunga nezvekushanda kwekupfapfaidza, kuramba kupisa uye hunhu hwemakanika ezvipfeko zvisingapindi mvura zvakakwana, zvinofungidzirwa kuti huwandu hwakanyanya hwekuwedzera hwehydroxyethyl cellulose i1‰.
Neoprene latex iri mujira remvura rinopfapfaidzwa nekukurumidza rinoisa asphalt uye emulsified asphalt ine musiyano mukuru mu polarity uye density, izvo zvinotungamira mukubvisa zvinhu A munguva pfupi panguva yekuchengetera. Naizvozvo, panguva yekuvaka panzvimbo iyi inoda kusanganiswa zvakaenzana isati yapfapfaidzwa, zvikasadaro inotungamira nyore nyore mutsaona dzemhando yepamusoro. Hydroxyethyl cellulose inogona kugadzirisa zvinobudirira dambudziko rekubvisa zvidimbu zvemvura zvinopfapfaidzwa nekukurumidza zvinoisa asphalt. Mushure memwedzi mumwe wekuchengetera, hapasisina kubvisa zvidimbu. Viscosity yesystem haina kuchinja zvakanyanya, uye kugadzikana kwakanaka.
kutarisa
1) Mushure mekunge hydroxyethyl cellulose yawedzerwa kune rabha asphalt inopfapfaidzwa nekukurumidza, kuramba kupisa kwejira risingapindi mvura kunovandudzwa zvikuru, uye dambudziko remabubbles akakora pamusoro pejira rinovandudzwa zvikuru.
2) Zvichienderana nepfungwa yekuti haikanganisi maitiro ekupfapfaidza, mashandiro ekugadzira firimu uye hunhu hwemakanika, hydroxyethyl cellulose yakawanikwa kuti ndeye hydroxyethyl cellulose ine viscosity ye10 000 mPa·s, uye huwandu hwekuwedzera hwaive 1‰.
3) Kuwedzerwa kwehydroxyethyl cellulose kunovandudza kugadzikana kwekuchengetwa kwejira remvura rinopfapfaidzwa nekukurumidza rinoisa asphalt, uye hapana delamination inoitika mushure mekuchengetwa kwemwedzi mumwe chete.
