Ububanzi besicelo:
I-Emulsifier yebitumen eshintshiwe ye-SBS eqhekekile ngokumaphakathi iyi-cationic emulsifier yebitumen eguquliwe ye-SBS. Isetshenziswa kakhulu ekukhiqizeni i-emulsification yebitumen eguquliwe ye-SBS yongqimba olunamathelayo, ungqimba lokuvalwa kwamatshe, ukuvimbela amanzi, njll. I-emulsifier incibilika kalula emanzini, ayidingi ukulungiswa kwe-asidi, kulula ukuyisebenzisa nokuyisebenzisa, futhi ingasetshenziswa. ekukhiqizeni ama-coatings angangeni manzi asekelwe emanzini anebitumeni.
incazelo yomkhiqizo:
I-SBS elungisiwe yebitumen emulsifier eqhekekile ngokumaphakathi iyi-emulsifier ekhethekile yebitumen eguquliwe ye-cationic SBS. Incibilika kalula emanzini, asikho isidingo sokulungisa i-asidi, kulula ukuyisebenzisa nokuyisebenzisa. Ingasetshenziswa ekukhiqizeni i-bitumen esekelwe emanzini engangeni manzi.
Imiyalelo:
Lapho ukhiqiza i-bitumen e-emulsified, i-bitumen emulsifier idinga ukukalwa ngokuhambisana nomthamo we-bitumen emulsifier emingceleni yezobuchwepheshe, bese yengezwa emanzini, inyakaziswa futhi ishiselwe ku-60-70 ° C, kuyilapho i-bitumen ishisa ku-170-180 ° C. . Lapho izinga lokushisa lamanzi kanye nezinga lokushisa letiyela lifinyelela izinga, ukukhiqizwa kwebitumen emulsified kungase kuqale.
Uma usebenzisa i-middle-crack emulsifier yebitumen eguquliwe ye-SBS, udinga ukunaka amaphuzu alandelayo:
1. I-Emulsifier idinga ukugcinwa kude nokukhanya, endaweni epholile, eyomile, futhi ivalwe.
2. Ibitumen evamile idinga ukushintshwa itiyela kuqala ukuze kukhiqizwe i-SBS eguquliwe bese ihlanganiswa.
3. Ngaphambi kokusetshenziswa, ukuhlolwa kwesampula encane kufanele kwenziwe ukuze kutholakale inani le-emulsifier nezimo zokusebenza.
4. Phakathi nenqubo yokukhiqiza, izinga lokushisa lamanzi kanye nezinga lokushisa lebitume kufanele kugcinwe kuzinzile ukuze kugwenywe amazinga okushisa aphezulu kakhulu noma aphansi.
