I-Hydroxyethyl cellulose (HEC) sisongezo esibalulekileyo esinemisebenzi emininzi edlala indima ephambili ekutshizeni irubha yokubeka i-asphalt yokugquma kwamanzi. Imisebenzi yayo ephambili ibandakanya ukutyeba, ukugcinwa kwamanzi, ukulungiswa kwe-rheology kunye nokuzinzisa kokumiswa.
1. Ukuqina kwesiphumo
Njenge-non-ionic thickener, i-hydroxyethyl cellulose inokunyusa kakhulu i-viscosity ye-asphalt efafazwayo ekhawulezayo yokubeka i-asphalt yokugquma kwamanzi. Ngenxa yeempawu zayo ezikhethekileyo ze-viscosity ephezulu, i-HEC inokunyusa ngokufanelekileyo i-viscosity yesakhiwo sokugquma ukuze ikwazi ukugcina ukuhambelana okufanelekileyo ngexesha lenkqubo yokwakha. Lo msebenzi ubaluleke kakhulu ekutshizeni ukwakhiwa, kuba i-viscosity efanelekileyo inceda ipeyinti ukuba isasazwe ngokulinganayo, inciphise i-sagging, kwaye iqinisekise ukuhambelana kobunzima bokugquma, ngaloo ndlela ufezekise imiphumo emihle kakhulu yokukhusela amanzi.
2. Ugcino lwamanzi
I-HEC inokugcinwa kwamanzi okugqwesileyo, okubaluleke kakhulu kwiingubo ezisekelwe emanzini. Kwizigqubuthelo ezigqunywe ngokukhawuleza kwirabha ye-asphalt efakwe kwi-asphalt engenamanzi, i-HEC inokucothisa isantya sokuphuma komphunga samanzi kwindawo yokwaleka ngokugcina ukufuma. Olu phawu aluncedi nje kuphela ukugcina imeko efumileyo yokugquma ngexesha lokwakhiwa kwaye luthintele ukwambathisa ukuba lome ngenxa yokulahleka kwamanzi ngokukhawuleza, kodwa lukhuthaza nokungena kwengubo kwi-substrate kwaye iphucula ukunamathela kwi-substrate, ngaloo ndlela iphucula i-coat. Ukusebenza ngokubanzi komgangatho wokuthintela amanzi.
3. Uhlengahlengiso lwe-Rheology
I-Rheology ibhekisela kwiimpawu zokuhamba kwepende phantsi kwesenzo samandla angaphandle. I-HEC isebenza njenge-rheology modifier ekutshizeni ngokukhawuleza i-rubber asphalt i-asphalt i-coatings engenamanzi, enokulungelelanisa ukuziphatha kwe-rheological ye-coating ukwenzela ukuba ibonise i-viscosity ephezulu kumazinga aphantsi okucheba kunye ne-viscosity ephezulu kumazinga aphezulu okucheba. I-viscosity ephantsi. Oku kucheba-thinning rheological ukuziphatha inceda impompo yepeyinti kunye isitshizi kwisixhobo sokutshiza kwaye ngokukhawuleza ubuyela viscosity eliphezulu emva kwesicelo, ngaloo ndlela kuncitshiswe ukopha ipeyinti kunye nokuqinisekisa ukuguda kunye nokufana yokwambathisa. .
4. Ukumiswa kunye nesiphumo sokuzinzisa
Ekutshizeni ngokukhawuleza i-asphalt ye-asphalt yokufakela i-asphalt yokungena kwamanzi, iinqununu ezahlukeneyo eziqinileyo, ezifana ne-rubber particles, fillers, njl., Zinokuhlala kwi-coating ngenxa yokungafani kobuninzi. Ngokwenza i-high-viscosity network structure, i-HEC inokumisa ngokufanelekileyo ezi ngqungquthela eziqinileyo kwaye zibathintele ekuzinzeni ngexesha lokugcinwa kunye nokwakhiwa. Oku kuzinzisa ukumiswa kunceda ukugcina ukufana kwepeyinti kunye nokuqinisekisa ukuba ipeyinti efafaziweyo inokwakheka okuhambelanayo, ngaloo ndlela yenza uluhlu olufana nolungenamanzi emva kokunyanga nokuphucula umphumo wokuthintela amanzi.
5. Ukuphuculwa komsebenzi wokwakha
Imisebenzi emininzi ye-HEC inokuphucula kakhulu ukusebenza kokwakhiwa kokutshiza i-rubber ekhawulezayo yokubeka i-asphalt yokugquma kwamanzi. Okokuqala, umphumo we-HEC wokuqina kunye nomsebenzi wohlengahlengiso lwe-rheology yenza ipeyinti ibe nokusebenza kakuhle ngexesha lokwakhiwa kokutshiza, kulula ukuyisebenzisa kwaye yenza i-coating egudileyo. Okwesibini, ukugcinwa kwayo kwamanzi kunceda ekuphuculeni ukunamathela kwepeyinti kwi-substrate kunye nokunciphisa iziphene zokugquma ezibangelwa kukuqhekeka okomileyo. Ukongezelela, umphumo wokumisa ukumiswa kwe-HEC unokugcina ukulungelelaniswa kwezithako zokugqoka, ngaloo ndlela kuqinisekiswe iipropati ezizinzile zomzimba zengubo emva kokwakhiwa kunye nokwandisa ubomi benkonzo yokugqoka.
Ukusetyenziswa kwe-cellulose ye-hydroxyethyl ekutshizeni i-rubber ekhawulezayo yokubeka i-asphalt yokugquma kwamanzi idlala indima ebalulekileyo kwiinkalo ezininzi. Ayinakwandisa kuphela i-viscosity yepeyinti kwaye ikhulise ukugcinwa kwamanzi, kodwa iphinda ilungelelanise iimpawu ze-rheological zepeyinti, izinzile iinqununu eziqinileyo kwipeyinti, kwaye iphucula umsebenzi wokwakha. Ezi ziphumo ngokudibeneyo ziqinisekisa ukusebenza kunye nokuqina kokugquma kwizicelo ezisebenzayo, ukwenza i-hydroxyethyl cellulose ibe sisongezo esiyimfuneko ekutshizeni irabha yokubeka i-asphalt yokugquma amanzi. Ngokukhetha okufanelekileyo kunye nokusetyenziswa kwe-HEC, ukusebenza okubanzi kweengubo zokugquma kwamanzi kunokuphuculwa kakhulu, ngaloo ndlela kunikeze isisombululo esinokwethenjelwa ngakumbi sokwakha ukukhuselwa kwamanzi.
