Polymer yakagadziriswa bhitumini isingapindi mvura
Kuputira kwebitumen isingapindi mvura yakagadzirwa nepolymer ipurasitiki inonyungudutswa nemvura kana kuti inonyungudutswa inogadzirwa nebhitumen sechinhu chepakutanga uye inogadziriswa nepolymers dzemamorekuru akawanda.
Zvinoreva chifukidziro chisina mvura chakagadzirwa neasphalt kana kuti chinodzivirira mvura chakagadzirwa neasphalt sechinhu chepasi uye chakagadziridzwa nemapolymers emhando yepamusoro, kunyanya marubha akasiyana-siyana. Rudzi urwu rwechifukidziro runogonawo kunzi chifukidziro chisina mvura chakagadzirwa neasphalt chakagadziriswa nerabha, icho chakavandudza zvikuru kuchinjika, kuramba kutsemuka, simba rekukwesha, kuramba kupisa kwakanyanya uye kwakaderera, uye hupenyu hwebasa zvichienzaniswa nechifukidziro chakagadzirwa neasphalt.
Mhando huru ndeiyi
Kuputira kusina mvura kwakagadziriswa nerabha, asphalt,
Mvura emulsion mhando neoprene rabha asphalt isapinda mvura,
Kuputira kwemvura kweSBS rabha yakagadziriswa asphalt, nezvimwewo.
Yakakodzera mapurojekiti ekudzivirira mvura akadai sematenga, pasi, pasi pevhu rekongiri nezvimbuzi zvine magiredhi eII, III neIV asingapindi mvura.
Rabha yakagadziriswa asphalt isingapindi mvura inonamirwa
Kuputira kwemvura kwebhitumini yakagadziriswazve rabha kunogona kukamurwa kuva mhando ye solvent uye mhando ye emulsion yemvura zvichienderana nepakati yakasiyana yekupararira.
Kuputira mvura kweasphalt kwakagadzirwa nerabha yakagadziriswa neasphalt isina mvura kunogadzirwa neasphalt yakadzorerwa semodifier, peturu sesolvent, ichiwedzera zvimwe zvinozadza zvakaita setalc, calcium carbonate, nezvimwewo, mushure mekudziya nekukurunga. Zvakanakira ndezvekuti inovandudza kuchinjika uye kugara kwenguva refu kweasphalt isina mvura, uye ine mhando dzakasiyana dzezvinhu zvakagadziriswa, mutengo wakaderera, uye kugadzirwa kuri nyore. Zvisinei, nekuda kwekushandiswa kwepeturu sesolvent, kutarisirwa kunofanira kupihwa kudzivirira moto nemhepo panguva yekuvaka, uye mifananidzo yakawanda inodiwa kuti pave nefirimu rakakora riri nani. Yakakodzera denga rezvivakwa zvemaindasitiri nevehurumende, madziva epasi, mabhiriji, maculvert nemamwe mapurojekiti, pamwe nekuchengetedzwa kwematenga ekare.
Rubber modified bitumen waterproof coating yakagadzirwa ne anionic regenerated latex uye anionic bitumen latex. Zvidimbu zverabha yakagadziridzwa ne petroleum bitumen zvinopararira mumvura uye zvinogadzirwa ne anionic surfactants. . Coating inoshandisa mvura sechinhu chinoparadzira, uye ine zvakanakira kuti haina chepfu, haina hwema, uye haibati. Inogona kuiswa muchando patembiricha yemumba uye inogona kuiswa panzvimbo ine hunyoro zvishoma isina mvura yakamira. Coating inowanzo putirwa nejira regirazi fiber kana synthetic fiber reinforced felt kuti igadzire layer isingapindi mvura, uye caulking paste inowedzerwa panguva yekuvaka kuti iwane mhedzisiro iri nani yekudzivirira mvura. Coating yacho yakakodzera kudzivirira mvura yedenga rekongiri yezvivakwa zvemaindasitiri nezvehurumende; kudzivirira mvura yedenga rekupisa ne asphalt perlite se thermal insulation; kudzivirira hunyoro hwezvivakwa zvepasi pevhu, kugadzirisa matenga ekare e linoleum, uye kugadzirisa matenga akasimba asingapindi mvura.
Mvura emulsion mhando neoprene rabha Asphalt isapinda unhani
Kuputira kusina mvura kwechloroprene rabha asphalt, chloroprene rabha, asphalt, kunoumbwa ne cationic chloroprene latex uye cationic asphalt emulsion. Kwakagadzirwa ne chloroprene rabha uye petroleum asphalt particles. Kunoumbwa nekupararira mumvura zvakadzikama nerubatsiro rwe cationic surfactants. Rudzi rwekuputira kusina mvura kwerudzi rwe emulsion yemvura.
Nekuda kwekushandurwa kweneoprene, chifukidziro ichi chine zvakanakira zviviri zve neoprene neasphalt. Chine simba rakanaka rekudzivirira mamiriro ekunze uye ngura, chinochinjika zvakanyanya, chinotambanuka uye chinonamatira, uye chinochinjika zvakasimba pakuchinjika kwechikamu chepasi. , Firimu rekuputira rinodziya zvishoma harina kupfava, tembiricha yakakwira haifambi, firimu rekuputira rakakora uye rakakwana, uye simba rakanaka rekudzivirira mvura. Uyezve, pendi yerabha yeasphalt yemvura-emulsion neoprene inoshandisa mvura semushonga, iyo isingangove nemutengo wakaderera chete, asiwo ine zvakanakira zvekusvibiswa kusina chepfu, kusingatsvi, uye kusvibiswa kwezvakatipoteredza panguva yekuvaka.
Yakakodzera kudzivirira mvura padenga, kudzivirira mvura pamadziro uye kudzivirira mvura pasi pezvivakwa zvemaindasitiri nezvehurumende, kudzivirira mvura pamapaipi pasi pevhu nemidziyo, uye yakakodzerawo kugadzirisa nekugadzikisa mvura inobuda mudzimba dzekare.
SBS rabha yakagadziriswa asphalt isapinda mvura yekuputira
Kuputira mvura kweSBS kwakagadziriswa asphalt imhando yekuvhara mvura kweasphalt inonyungudika inoumbwa neasphalt, rabha SBS resin (styrene-butadiene-styrene block copolymer) uye masurfactants nezvimwe zvinhu zvepolymer. Zvakanakira zvekuvhara uku ndiko kuchinjika kwakanaka kwekupisa kwakaderera, kuramba kupwanyika kwakasimba, kushanda zvakanaka kwekubatanidza, uye kuramba kukwegura kwakanaka. Yakabatanidzwa nejira regirazi fiber nezvimwe zvitunha zvakasimbiswa. Ine kushanda kwakanaka kwemvura uye inogona kushandiswa pakuvaka kunotonhora. Iyo ipurasitiki yakanaka yemvura yepakati-range.
Yakakodzera kuvaka mabhesi akaomarara asingapindi mvura uye asingapindi mvura, akadai sezvimbuzi, makamuri epasi, makicheni, madziva emvura, nezvimwewo, kunyanya yakakodzera mapurojekiti ekudzivirira mvura munzvimbo dzinotonhora.
