Scope ntawm kev siv:
Nruab nrab tawg SBS hloov bitumen emulsifier yog cationic emulsifier rau SBS hloov bitumen. Nws yog tsuas yog siv nyob rau hauv lub emulsification ntau lawm ntawm SBS hloov bitumen rau nplaum txheej, gravel sealing txheej, lub tsev waterproofing, thiab lwm yam. Lub emulsifier yog yooj yim soluble nyob rau hauv dej, tsis yuav tsum tau acid hloov, yog ib qho yooj yim rau kev khiav lag luam thiab siv, thiab yuav siv tau. nyob rau hauv zus tau tej cov waterproof water-based bitumen-based waterproof txheej.
Khoom piav qhia:
Nruab nrab-tawg SBS hloov bitumen emulsifier yog ib qho tshwj xeeb emulsifier rau cationic SBS hloov bitumen. Yooj yim soluble hauv dej, tsis tas yuav kho cov kua qaub, yooj yim rau kev khiav lag luam thiab siv. Nws tuaj yeem siv rau hauv kev tsim cov dej tsis muaj dej-raws li bitumen-based waterproof coatings.
Cov lus qhia:
Thaum tsim cov emulsified bitumen, lub bitumen emulsifier yuav tsum tau hnyav raws li qhov ntau npaum ntawm bitumen emulsifier nyob rau hauv cov kev tsis, ces ntxiv rau dej, stirred thiab rhuab mus rau 60-70 ° C, thaum lub bitumen yog rhuab mus rau 170-180 ° C. . Thaum cov dej kub thiab bitumen kub ncav cuag tus qauv, emulsified bitumen ntau lawm tuaj yeem pib.
Thaum siv mid-crack SBS hloov bitumen emulsifier, koj yuav tsum tau xyuam xim rau cov ntsiab lus hauv qab no:
1. Emulsifier yuav tsum tau muab cia kom deb ntawm lub teeb, hauv qhov chaw txias, qhuav, thiab kaw.
2. Ordinary bitumen yuav tsum tau hloov kho bitumen ua ntej los tsim SBS hloov bitumen thiab ces emulsified.
3. Ua ntej siv, yuav tsum tau ua ib qho kev sim me me los txiav txim siab txog cov emulsifier thiab kev ua haujlwm.
4. Thaum lub sij hawm tsim khoom, cov dej kub thiab bitumen kub yuav tsum ruaj khov kom tsis txhob muaj qhov kub thiab txias ntau dhau.
