Kufotokozera Kwachidule:

Chingwe chomangira, chosweka: cholimba chomangira cholimba chomwe chimathandiza kuti ma CRS emulsions asungidwe bwino.

Konzani kulimba kwa msewu: Monga chomangira mu chisakanizo cha phula, phula lopangidwa ndi emulsified limatha kumangirira tinthu ta miyala pamodzi kuti tipange kapangidwe kolimba ka msewu, zomwe zimapangitsa kuti msewuwo ukhale wolimba komanso wokana kupanikizika.

Phula lopangidwa ndi emulsified limagwiritsidwa ntchito kwambiri pa ntchito yomanga misewu, kukonza ndi kumanganso. Lingagwiritsidwe ntchito ngati chomangira mu zosakaniza za phula kuti liwongolere bwino kulimba ndi kukhazikika kwa msewu, komanso kuchepetsa ndalama zomangira komanso kuipitsa chilengedwe. Kuphatikiza apo, phula lopangidwa ndi emulsified lingagwiritsidwenso ntchito ngati chophimba chosalowa madzi, choteteza madzi padenga komanso choteteza madzi mkati mwa khoma, chokhala ndi ntchito yabwino kwambiri yosalowa madzi.

Kupaka phula lopangidwa ndi emulsifiers yapamwamba kwambiri kumapangitsa kuti ntchito yomanga ikhale yosavuta. Palibe chifukwa chotenthetsera phula kufika kutentha kwa 170 ~ 180°C musanagwiritse ntchito. Zinthu zamchere monga mchenga ndi miyala sizifunika kuumitsa ndi kutenthedwa, zomwe zingasunge mafuta ambiri ndi mphamvu yotentha. . Chifukwa chakuti phula lopangidwa ndi emulsion limagwira ntchito bwino, limatha kugawidwa mofanana pamwamba pa aggregate ndipo limamatira bwino, kotero limatha kusunga phula, kuchepetsa njira zomangira, kukonza mikhalidwe yomangira, ndikuchepetsa kuipitsa chilengedwe chozungulira. Chifukwa cha ubwino uwu, phula lopangidwa ndi emulsified siliyenera kokha misewu yomangira, komanso kuteteza malo otsetsereka a makoma, kuletsa madzi a denga ndi mapanga, kuteteza dzimbiri pamwamba pa zipangizo zachitsulo, kukonza nthaka yaulimi ndi thanzi la zomera, njanji zonse, kukhazikika kwa mchenga wa m'chipululu, ndi zina zotero. Limagwiritsidwa ntchito kwambiri m'mapulojekiti ambiri. Chifukwa phula lopangidwa ndi emulsified silingongowonjezera ukadaulo womangira phula lotentha, komanso kukulitsa kuchuluka kwa ntchito ya phula, phula lopangidwa ndi emulsified lakula mofulumira.

Emulsifier ya Asphalt ndi mtundu wa surfactant. Kapangidwe kake ka mankhwala kamakhala ndi magulu okonda lipophilic ndi hydrophilic. Imatha kuyamwa pamalo olumikizirana pakati pa tinthu ta asphalt ndi madzi, motero imachepetsa kwambiri mphamvu yaulere ya malo olumikizirana pakati pa asphalt ndi madzi, zomwe zimapangitsa kuti ikhale surfactant yomwe imapanga emulsion yofanana komanso yokhazikika.

Surfactant ndi chinthu chomwe chimachepetsa kwambiri kupsinjika kwa pamwamba pa madzi chikawonjezedwa pang'ono, ndipo chingasinthe kwambiri mawonekedwe ndi momwe dongosololi lilili, motero chimapangitsa kunyowa, emulsification, thovu, kutsuka, ndi kufalikira. , antistatic, mafuta, kusungunuka ndi ntchito zingapo kuti zikwaniritse zofunikira pakugwiritsa ntchito.

Kaya ndi mtundu wanji wa surfactant, molekyu yake nthawi zonse imakhala ndi gawo la unyolo wa hydrocarbon wosakhala polar, hydrophobic ndi lipophilic ndi gulu la polar, oleophobic ndi hydrophilic. Zigawo ziwirizi nthawi zambiri zimakhala pamwamba. Malekezero awiri a molekyulu yogwira ntchito amapanga kapangidwe kosagwirizana. Chifukwa chake, kapangidwe ka molekyulu ya surfactant kamadziwika ndi molekyulu ya amphiphilic yomwe ndi lipophilic ndi hydrophilic, ndipo ili ndi ntchito yolumikiza magawo a mafuta ndi madzi.

Pamene ma surfactants apitirira kuchuluka kwina m'madzi (critical micelle concentration), amatha kupanga ma micelles kudzera mu hydrophobic effect. Mlingo woyenera wa emulsifier wa asphalt wothira madzi ndi waukulu kwambiri kuposa kuchuluka kwa critical micelle.
