Ubungakanani besicelo:
Ibhitumene ehlaziyiweyo ephakathi eqhekekileyo emulsifier ye-cationic sisihluzi se-cationic sebhitumene elungisiweyo ye-SBS. Isetyenziselwa ikakhulu kwimveliso ye-emulsification ye-SBS eguqulweyo yebhitumene yomaleko wokuncamathelisa, umaleko wokutywinwa kwegravel, ukuthintela ukwakhiwa kwamanzi, njl. njl. kwimveliso yebhitumene engenamanzi esekelwe emanzini.
Ingcaciso yeMveliso:
Ibhitumene ehlaziyiweyo ephakathi eqhekekileyo ye-SBS sisifinyisi-emulsifier esikhethekileyo se-cationic SBS elungisiweyo yebhitumene. Inyibilika ngokulula emanzini, akukho mfuneko yokulungelelanisa i-asidi, kulula ukuyisebenzisa kunye nokusetyenziswa. Ingasetyenziselwa ukuveliswa kwe-bitumen-based based bitumen-based based coatings.
Imiyalelo:
Xa uvelisa i-bitumen e-emulsified, i-bitumen emulsifier kufuneka ilinganiswe ngokwe-dosage ye-bitumen emulsifier kwiiparamitha zobugcisa, emva koko yongezwa emanzini, ixutywe kwaye ishushu kwi-60-70 ° C, ngelixa i-bitumen ifudumala kwi-170-180 ° C. . Xa ubushushu bamanzi kunye nobushushu bebhitumene bufikelela kumgangatho, ukuveliswa kwebhitumene emulsified kunokuqalisa.
Xa usebenzisa i-middle-crack emulsifier ye-bitumen eguqulweyo ye-SBS, kufuneka ubeke ingqalelo kula manqaku alandelayo:
1. I-Emulsifier kufuneka igcinwe kude nokukhanya, kwindawo epholileyo, eyomileyo, kwaye ivalwe.
2. Ibhitumene eqhelekileyo kufuneka itshintshwe ibhitumene kuqala ukuze ivelise ibhitumene elungisiweyo ye-SBS ize emva koko yenziwe imifuziselo.
3. Ngaphambi kokusetyenziswa, uvavanyo oluncinci lwesampula kufuneka luqhutywe ukufumanisa inani le-emulsifier kunye neemeko zokusebenza.
4. Ngethuba lenkqubo yokuvelisa, ubushushu bamanzi kunye ne-bitumen kufuneka bugcinwe buzinzile ukuze kugwenywe ubushushu obuphezulu okanye obuphantsi.
