Chikamu chekushandisa:
SBS yakatsemuka zvepakati nepakati yakagadziridzwa bhitumeni emulsifier is cationic emulsifier yeSBS yakagadziridzwa bhitumini. Inonyanya kushandiswa mukugadzira emulsification yeSBS yakagadziridzwa bhitumen yekunamatira layer, gravel sealing layer, kuvaka kwekudzivirira mvura, etc. Iyo emulsifier inonyungudika nyore mumvura, haidi kugadzirisa asidi, iri nyore kushanda nekushandisa, uye inogona kushandiswa. mukugadzirwa kwemvura isina mvura-based bitumen-based waterproof coatings.
tsananguro yechigadzirwa:
Emulsifier yepakati-yakatsemuka SBS yakagadziridzwa bhitumeni emulsifier yakakosha yecationic SBS yakagadziridzwa bhitumeni. Zviri nyore soluble mumvura, hapana chikonzero chekugadzirisa asidhi, nyore kushanda uye kushandisa. Inogona kushandiswa mukugadzirwa kwemvura isina mvura-based bitumen-based based waterproof coatings.
Mirayiridzo:
Paunenge uchigadzira bhitumeni yakashongedzwa, bhitumeni emulsifier inoda kuyerwa zvinoenderana nechiyero chebhitumini emulsifier muhunyanzvi paramita, yozowedzerwa kumvura, yamutswa uye inopisa kusvika 60-70 ° C, nepo bhitumeni ichidziya kusvika 170-180 ° C. . Kana tembiricha yemvura uye tembiricha yebhitumini yasvika pachiyero, kugadzirwa kwebhitumini kunogona kutanga.
Paunenge uchishandisa yepakati-mutswe SBS yakagadziridzwa bhitumeni emulsifier, unofanirwa kuterera kune anotevera mapoinzi:
1. Emulsifier inoda kuchengetwa kure nechiedza, munzvimbo inotonhorera, yakaoma, uye yakavharwa.
2. Bhitumeni yakajairika inoda kugadziridzwa bhitumene kutanga kuti ibudise SBS yakagadziridzwa bhitumeni yozoiswa emulsified.
3. Usati washandiswa, muedzo muduku wemuenzaniso unofanirwa kuitwa kuti uone kuwanda kwe emulsifier uye mamiriro ekushanda.
4. Panguva yekugadzira, tembiricha yemvura uye tembiricha yebhitumini inofanira kuchengetedzwa yakatsiga kudzivirira kutonhora kwakanyanya kana kuderera.
