Pankhani yokonza njira zopewera misewu,kapangidwe kake kakang'onondi cationicphula losungunuka mofulumiraZimayimira ukadaulo wodziwika bwino wokonzanso misewu yopyapyala. Monga gawo lofunikira kwambiri mkati mwa dongosolo la phula lopangidwa ndi emulsifier, ma emulsifier amawongolera mwachindunji kukhazikika kwa kusungirako kwa emulsion, kulumikizana pakati pa phula ndi ma aggregates, magwiridwe antchito osakanikirana a zosakaniza, ndi nthawi yomwe imafunika kuti msewu utsegulidwe kuti magalimoto azitha kuyenda pambuyo pomanga. Ntchito za misewu ku China zimatsutsidwa ndi mitundu yosiyanasiyana ya aggregate lithology, kusintha kwakukulu kwa nyengo m'madera, ndi nthawi yomanga yolimba. Emulsifier ya asphalt ya cationic yokhala ndi mgwirizano waukulu komanso magwiridwe antchito okhazikika ndi ofunikira kwambiri pakutsimikizira ubwino wokonza misewu ndikuchepetsa zoopsa zomanga pamalopo.
Shanghai Qixuan Chemical yakhala ikugwira ntchito kwambiri pakupanga mankhwala atsopano a uinjiniya wa misewu. QXME 87 cationic asphalt emulsifier ndi chinthu chokhwima chomwe chimatsimikiziridwa kudzera mu mayeso ambiri a labotale komanso ntchito zingapo za uinjiniya wamunda. Yapangidwa makamaka kuti igwiritsidwe ntchito pamakina a cationic quick-set (CQS) emulsified asphalt ndi micro-surfacing, kupereka mayankho odalirika a emulsification pamapulojekiti oteteza misewu m'nyumba.
QXME 87 ndi chosakaniza cha asphalt chopangidwa ndi amine chokhala ndi amine chomwe chili ndi amine yocheperako ya 370. Zigawo zambiri za amine zomwe zimagwira ntchito zimapatsa chinthucho mphamvu yabwino kwambiri yopangira emulsifying ndi mphamvu ya chaji, zomwe zimathandiza kuti asphalt yoyambira ipangidwe bwino pansi pa acidity. Chogulitsachi ndi chamadzimadzi chofiirira, chokhala ndi kuchuluka kuyambira 0.97 mpaka 1.05 g/cm³ pa 25°C. Imasunga madzi abwino kutentha kozungulira ndipo ndi yosavuta kudyetsa popanda kutentha ndi kusungunuka. Imagwirizana ndi mizere yopanga phula yopangidwa ndi mtundu wa batch komanso yopitilira ku China yotumizira zinthu, kuyeza ndi kusakaniza. Ili ndi mphamvu zokhazikika za physicochemical, imakana kugawanika ndi kunyowa pansi pa mikhalidwe yabwino yosungira, zomwe zimathandiza kuyang'anira nyumba yosungiramo zinthu kwa opanga. Imachepetsa bwino kusinthasintha kwa emulsion komwe kumachitika chifukwa cha kusiyanasiyana kwa chakudya ndikuwonetsetsa kuti phula lopangidwa ndi emulsion limagwira ntchito bwino nthawi zonse kuchokera ku batch kupita ku batch.
Popeza imapindula ndi kapangidwe kake ka molekyulu, phula lopangidwa ndi QXME 87 lomwe limapangidwa ndi emulsified lomwe lili ndi ubwino wambiri wodziwika bwino.
Choyamba, imakwaniritsa bwino kwambiri emulsion-to-aggregate compatibility ndipo imagwirizana ndi ma aggregates osiyanasiyana a lithologies ndi acid-base properties. Ma aggregates omwe amapezeka pa ntchito zapakhomo amasiyana kwambiri pakupanga mankhwala pamwamba, kuchuluka kwa matope ndi ukhondo. Ma emulsifier ambiri nthawi zambiri amavutika ndi kuchuluka kosalamulirika kwa kusweka ndi phula losafanana pamene chakudya cha aggregate chikusintha. Dongosolo la emulsification la QXME 87 limasonyeza kulekerera kwakukulu kwa ma aggregates osiyanasiyana. Madontho a asphalt opangidwa ndi emulsified amatha kupanga mafilimu ofanana komanso okhuthala a asphalt pamalo a aggregate, zomwe zimapangitsa kuti pakhale kugwirizana pakati pa asphalt ndi miyala. Imachepetsa kwambiri kulephera kwa zomangamanga komwe kumachitika chifukwa cha kusinthasintha kwa zinthu zopangira aggregate ndikuchepetsa mwayi wokonzanso ntchito.
Chachiwiri, chisakanizochi chimapereka magwiridwe antchito abwino osakaniza ndi kugwira ntchito bwino kwa matope. Pakusakaniza zosakaniza za matope ang'onoang'ono, liwiro la kusweka kwa dongosololi likhoza kulamulidwa bwino. Chisakanizo cha matope chimapangitsa kuti ntchito yokonza matope ikhale yosalala, kupewa kusonkhana msanga ndi kuyika matope, ndikuwonetsetsa kuti misewu ikhale yosalala mukayika.
Chachitatu, ikukwaniritsa zofunikira za uinjiniya kuti magalimoto atsegulidwe mwachangu. Kugwiritsa ntchito phula lopangidwa ndi pulasitiki wo ...
Chachinayi, phula lopangidwa ndi emulsified lomwe lamalizidwa limakhala ndi kukhazikika kwabwino kwambiri pakusungira. Emulsion yopangidwayo imalimbana ndi kugawikana ndi kulekanitsidwa mkati mwa nthawi yosungidwa yomwe yatchulidwa, ndikukulitsa nthawi yosungira ndi kunyamula ma emulsions omalizidwa. Imachepetsanso zinyalala za zinthu ndi zoopsa zaukadaulo zomwe zimachitika chifukwa cha kulephera kwa emulsion msanga.
Kutengera mayeso a nthawi yayitali komanso ndemanga za mapulojekiti am'munda, njira ziwiri zodziwika bwino za QXME 87 zafotokozedwa pansipa. PH ya machitidwe onse awiriwa yasinthidwa kukhala 1.5–2.5 yokhala ndi hydrochloric acid, yogwiritsidwa ntchito pokonzekera zitsanzo za mu labotale komanso kupanga mafakitale.

Latex ndi gawo lofunikira kwambiri mu makina ang'onoang'ono opangidwa kuti awonjezere kukana kuwonongeka ndi kukana ming'alu ya slurry seal layer yokonzedwa. Fomula iyi ndi yoyenera pokonza ma micro-surfacing m'misewu yayikulu komanso m'misewu yamatauni. Mafomula onsewa ndi osavuta kugwiritsa ntchito pamizere yopangira phula yopangidwa ndi emulsified. Makasitomala amatha kusintha mlingo wa emulsifier ndi ma formula ratios ndi chithandizo chaukadaulo kuchokera ku Shanghai Qixuan Chemical, zomwe zikugwirizana ndi zofunikira za polojekiti kutengera ma grade osankhidwa a phula, katundu wophatikizidwa ndi zidziwitso zaukadaulo.
Ponena za ntchito za uinjiniya, QXME 87 imagwira ntchito pokonza njira zodzitetezera komanso kukonza zinthu zadzidzidzi pamisewu yothamanga, misewu yadziko lonse ndi yachigawo, komanso misewu ya m'matauni. Monga njira yokonza yocheperako yokhala ndi liwiro lomanga mwachangu, mtengo wocheperako, kuletsa madzi kulowa m'madzi komanso kusawonongeka, ukadaulo wocheperako ndi womwe umagwiritsidwa ntchito kwambiri pochiza zolakwika za pamsewu. Phula lopangidwa ndi cationic quick-set emulsified limagwiritsidwa ntchito kwambiri pokonza mabowo a pamsewu komanso kugwiritsa ntchito malaya omatira. Zochitika zonsezi zimapangitsa kuti pakhale zofunikira kwambiri pa liwiro losweka, kukhazikika kosakanikirana komanso mphamvu yoyambirira ya phula lopangidwa ndi emulsified. Potsimikiziridwa m'mapulojekiti ambiri, QXME 87 imagwira ntchito modalirika pansi pa mikhalidwe yogwirira ntchito iyi.
Cholinga chachikulu cha uinjiniya wokonza misewu ndikuwonjezera nthawi yogwirira ntchito pamsewu ndikuchepetsa ndalama zogwirira ntchito yokonza nthawi yonse. Ma emulsifier apamwamba kwambiri sizinthu zopangira phula lopangidwa ndi emulsified, komanso maziko aukadaulo a yankho lonse lokonza. Ngakhale tikupereka zinthu za QXME 87, Shanghai Qixuan Chemical imapereka phukusi lathunthu lautumiki waukadaulo, kuphatikiza chitsogozo chokonza zolakwika pakupanga, kukonza njira zopangira ndi chithandizo chaukadaulo chomanga pamalopo. Kuyambira mayeso a emulsification a labu ndi kupanga koyeserera pamizere yopanga mpaka kutsatira zaukadaulo pamalo omanga, timathandiza makasitomala kupanga phula lopangidwa ndi emulsified loyenerera komanso kupereka bwino mapulojekiti okonza misewu.
Ngakhale kuti ku China kukusintha kosalekeza kwa zomangamanga zoyendera, kufunikira kwa zipangizo zopangira phula lolimba komanso logwira ntchito bwino pamsika wokonza misewu yopewera kukupitilizabe kukwera. Ndi khalidwe lokhazikika la zinthu, kusinthasintha kwakukulu komanso mbiri yotsimikizika yaukadaulo, QXME 87 cationic asphalt emulsifier imagwira ntchito ngati njira yodalirika yamapulojekiti a phula opangidwa ndi phula okhala ndi cationic mwachangu, zomwe zimathandiza kukonza bwino komanso kupeza bwino ntchito yokonza misewu yapakhomo komanso kuteteza chitetezo cha magalimoto pamsewu.
