Nkọwa Dị Mkpirikpi:

Nchikota oyi akwa, oyi akwa gbajiri agbaji: emulsifier siri ike nke nwere oke viscosity dị elu nke na-enyere aka na nchekwa nke emulsions CRS.

Mee ka ụzọ ahụ sie ike: Dịka ihe na-ejikọ ọnụ na ngwakọta asfalt ahụ, asfalt emulsified nwere ike ijikọ mkpụrụ okwute ahụ nke ọma iji mepụta usoro pavement siri ike, na-eme ka ụzọ ahụ sie ike ma na-eguzogide nrụgide nke ya.

A na-ejikarị asphalt emulsified eme ihe n'ọrụ owuwu ụzọ, ndozi na nrụzigharị. Enwere ike iji ya dị ka ihe na-ejikọ ihe na ngwakọta asphalt iji melite ogologo oge na nkwụsi ike nke elu ụzọ, ebe ọ na-ebelatakwa ọnụ ahịa owuwu na mmetọ gburugburu ebe obibi. Na mgbakwunye, enwere ike iji asphalt emulsified mee ihe dị ka mkpuchi mmiri na-adịghị egbochi mmiri, ihe na-egbochi mmiri na-anaghị ekpuchi elu ụlọ na ihe na-egbochi mmiri na-anaghị ekpuchi mgbidi dị n'ime ọwara, yana arụmọrụ mmiri na-anaghị ekpuchi mmiri nke ọma.

Paịpụ asfalt emulsified nke e ji ihe ndị emulsifier dị elu mee na-eme ka owuwu ebe ahụ dị mfe. Ọ dịghị mkpa ka a kpoo asfalt ahụ ọkụ ruo okpomọkụ dị elu nke 170 ~ 180°C tupu ejiri ya. Ihe ndị dị n'ime ala dị ka ájá na ajịrịja ekwesịghị ịkpọ nkụ ma kpoo ya ọkụ, nke nwere ike ịchekwa ọtụtụ mmanụ ọkụ na ike okpomọkụ. . . N'ihi na asfalt emulsion nwere ezigbo ọrụ, enwere ike kesaa ya n'elu mkpokọta ahụ ma nwee ezigbo njikọta na ya, ya mere ọ nwere ike ịchekwa oke asfalt, mee ka usoro owuwu dị mfe, melite ọnọdụ owuwu, ma belata mmetọ gburugburu ebe obibi. N'ihi uru ndị a, asfalt emulsified abụghị naanị maka imepe ụzọ, kamakwa maka nchekwa mkpọda nke ihe ndị e ji jupụta, igbochi mmiri nke ụlọ na ọgba, mgbochi ire ere nke ihe ígwè, mmezi ala ugbo na ahụike osisi, ihe owuwu okporo ụzọ zuru oke, idozi ájá ọzara, wdg. A na-ejikarị ya eme ihe n'ọtụtụ ọrụ. Ebe ọ bụ na asfalt emulsified nwere ike imeziwanye teknụzụ owuwu nke asfalt ọkụ, kamakwa ịgbasa oke ojiji nke asfalt, asfalt emulsified etolitela ngwa ngwa.

Asphalt emulsifier bụ ụdị surfactant. Nhazi kemịkalụ ya nwere otu lipophilic na hydrophilic. Enwere ike itinye ya n'ime njikọ dị n'etiti ihe ndị dị n'ime asphalt na mmiri, si otú a na-ebelata ike efu nke njikọ dị n'etiti asphalt na mmiri, na-eme ka ọ bụrụ surfactant nke na-emepụta emulsion otu na nke kwụsiri ike.

Surfactant bụ ihe nwere ike ibelata nrụgide elu mmiri nke ukwuu mgbe etinyere ya na obere ego, ma nwee ike ịgbanwe njirimara na ọnọdụ nke sistemụ ahụ nke ukwuu, si otú a na-emepụta mmiri mmiri, emulsification, ụfụfụ, ịsa, na mgbasa. , antistatic, mmanụ ọkụ, solubilization na usoro ọrụ iji mezuo ihe achọrọ maka ngwa bara uru.

N'agbanyeghị ụdị surfactant ọ bụla, molekul ya na-abụkarị akụkụ nke yinye hydrocarbon na-abụghị polar, hydrophobic na lipophilic na otu polar, oleophobic na hydrophilic. Akụkụ abụọ a na-adịkarị n'elu. Ngwụcha abụọ nke molekul na-arụ ọrụ na-emepụta nhazi asymmetric. Ya mere, a na-eji molekul nke surfactant mara molekul amphiphilic nke bụ ma lipophilic na hydrophilic, ma nwee ọrụ nke ijikọ usoro mmanụ na mmiri.

Mgbe ihe ndị na-eme ka mmiri dị n'ime mmiri gafere otu njupụta (njupụta dị mkpa nke micelle), ha nwere ike ịmepụta micelles site na mmetụta hydrophobic. Usoro emulsifier kacha mma maka asphalt emulsified dị ukwuu karịa njupụta micelle dị mkpa.
