Hydroxyethyl cellulose (HEC) yakakosha multifunctional additive iyo inoita basa rakakosha mukupfapfaidza nekukurumidza-kuseta rabha asphalt isina mvura. Mabasa ayo makuru anovhara kukora, kuchengetwa kwemvura, rheology kugadzirisa uye kumisa kudzikamisa.
1. Kukora mhedzisiro
Senge isiri-ionic thickener, hydroxyethyl cellulose inogona kuwedzera zvakanyanya viscosity yekupfapfaidza inokurumidza-kugadzika rabha asphalt isingapindi mvura. Nekuda kweiyo yakasarudzika yakakwirira viscosity maitiro, HEC inogona zvinobudirira kuwedzera maitiro eviscosity yekupfeka kuitira kuti igone kuchengetedza kuenderana kwakakodzera panguva yekuvaka. Iri basa rinonyanya kukosha pakupfapfaidza kuvaka, nekuti iyo viscosity yakakodzera inobatsira pendi kuti igovaniswe zvakaenzana, kuderedza sagging, uye kuve nechokwadi chekuenderana kwehukukutu hwekuputira, nekudaro kuwana yakanakisa kudzivirira mvura.
2. Mvura yekuchengetedza mhedzisiro
HEC ine yakanakisa kuchengetedza kwemvura, iyo inonyanya kukosha mumvura-based coatings. Mune yakapfapfaidzwa-yakavharidzirwa inokurumidza-kugadzika rabha asphalt isingapindi mvura, HEC inogona kudzikamisa mwero wekubuda kwemvura mujasi nekuchengetedza hunyoro. Ichi chimiro hachibatsiri chete kuchengetedza hunyoro hwehuputi panguva yekuvaka uye inodzivirira kuvhara kubva pakuoma nekuda kwekukurumidza kurasikirwa kwemvura, asiwo kunokurudzira kupinda kwechifukidzo pa substrate uye kunowedzera kunamatira kune substrate, nokudaro kunatsiridza The The whole performance of the waterproofing layer.
3. Rheology kugadzirisa
Rheology inoreva kuyerera kwepende pasi pekuita kwemasimba ekunze. HEC inoshanda seye rheology modifier mukupfapfaidza inokurumidza-kugadzika rubber asphalt isina mvura yekuputira, iyo inogona kugadzirisa rheological maitiro ejasi kuitira kuti iratidze viscosity yakakwirira pane yakaderera shear rates uye yakakwirira viscosity pakakwirira shear mitengo. Low viscosity. Iyi shear-kutetepa rheological maitiro anobatsira pombi yependi uye kupfapfaidza mumidziyo yekupfapfaidza uye nekukasira kudzoka kune yakakwira viscosity mushure mekushandisa, nekudaro ichidzikisa kubuda kwependi uye kuve nechokwadi kutsetseka uye kufanana kwejasi. .
4. Kumiswa uye kudzikamisa mhedzisiro
Mukupfapfaidza inokurumidza-kugadzika rabha asphalt isina mvura yekuputira, akasiyana masisitimu akasimba, senge rubha zvimedu, mafirita, nezvimwewo, anogona kugara mujasi nekuda kwekusiyana kwehutsi. Nekugadzira chimiro chepamusoro-viscosity network, HEC inogona kunyatso kumisa zvimedu izvi zvakasimba uye kudzivirira kubva pakugadzirisa panguva yekuchengetedza nekuvaka. Uku kudzikamisa kunobatsira kuchengetedza kufanana kwepende uye kuve nechokwadi chekuti pendi yakapfapfaidzwa ine chimiro chakafanana, nekudaro ichigadzira yunifomu isingapindi mvura mushure mekurapa nekuvandudza maitiro ekudzivirira mvura.
5. Kuvandudzwa kwekushanda kwekuvaka
Iwo akawanda mabasa eHEC anogona kuvandudza zvakanyanya kuita kwekuvaka kwekupfapfaidza nekukurumidza-kuseta rabha asphalt isina mvura yekupfeka. Chokutanga pane zvose, HEC's thickening effect uye rheology kugadzirisa basa inoita kuti pendi ive nekushanda kwakanaka panguva yekugadzirwa kwepfapfaidzo, iri nyore kuisa uye kugadzira jira rakatsetseka. Chechipiri, kuchengetwa kwayo kwemvura kunobatsira kuvandudza kunamatira kwepende kune substrate uye kunoderedza kukanganisa kwekuputira kunokonzerwa nekupwanya kwakaoma. Uye zvakare, iyo yekumisa kudzikamisa mhedzisiro yeHEC inogona kuchengetedza kuenderana kwekuputira zvigadzirwa, nekudaro kuve nechokwadi kugadzikana kwemuviri hunhu hwekuvhara mushure mekuvaka uye kuwedzera hupenyu hwebasa rejasi.
Kushandiswa kwehydroxyethyl cellulose mukupfapfaidza inokurumidza-kuseta rabha asphalt isina mvura machira kunoita basa rakakosha mune zvakawanda zvinhu. Haisi kungowedzera viscosity yepende uye inowedzera kuchengetedza kwemvura, asiwo inogadzirisa rheological properties yepende, inogadzirisa zvimedu zvakasimba mupende, uye inovandudza kushanda kwekuvaka. Izvi zvinokonzeresa pamwe chete zvinovimbisa kuita uye kusimba kweiyo yekupfeka mune inoshanda maapplication, zvichiita kuti hydroxyethyl cellulose ive yekuwedzera inodiwa mukupfapfaidza inokurumidza-kugadzika rabha asphalt isina mvura. Kuburikidza nekusarudzwa kwakanaka uye kushandiswa kweHEC, kushanda kwakazara kwekuvhara kwemvura kunogona kuvandudzwa zvakanyanya, nokudaro kupa mhinduro yakavimbika yekuvaka kudzivirira mvura.
