Tie oyi akwa, agbaji-site oyi akwa: siri ike emulsifier na karịsịa elu viscosity na-eme ka nchekwa kwụsie ike nke CRS emulsions.

Meziwanye ịdịte aka nke pavement: Dị ka onye na-ekekọta na ngwakọta asphalt, emulsified asphalt nwere ike jikọta akụkụ nkume ndị ahụ ọnụ iji mepụta ihe owuwu pavement siri ike, na-eme ka ịdịte aka na nkwụsi ike nke pavement dịkwuo mma.

A na-eji emulsified asphalt eme ihe n'ọtụtụ ebe n'iwu okporo ụzọ, nrụzi na ọrụ nrụzigharị.

Emulsified asphalt paving emepụtara na emulsifiers dị elu na-eme ka iwu ụlọ dị mfe. Ọ dịghị mkpa ikpo ọkụ asphalt na elu okpomọkụ nke 170 ~ 180 Celsius C tupu eji. Ihe ndị na-emepụta ihe ndị dị ka ájá na gravel adịghị mkpa ka akpọnwụ ma kpoo ọkụ, nke nwere ike ịchekwa ọtụtụ mmanụ ọkụ na ike ọkụ. . N'ihi na emulsion asphalt nwere ọrụ dị mma, enwere ike kesaa ya n'ụzọ zuru ezu n'elu mkpokọta ma nwee ezigbo adhesion na ya, ya mere ọ nwere ike ịchekwa ọnụ ọgụgụ nke asphalt, mee ka usoro ihe owuwu dị mfe, meziwanye ọnọdụ ihe owuwu, ma belata mmetọ na gburugburu ebe obibi. N'ihi uru ndị a, emulsified asphalt bụ bụghị naanị adabara paving ụzọ, kamakwa maka mkpọda nchebe nke jupụtara embankments, waterproofing nke ụlọ elu ụlọ na caverns, elu anticorrosion nke metal ihe, ugbo ala mma na osisi ahụ ike, n'ozuzu track bed nke ụgbọ okporo ígwè, ọzara ájá fixation, wdg A na-eji ya n'ọtụtụ ọrụ. N'ihi na emulsified asphalt nwere ike ọ bụghị naanị melite ewu technology nke na-ekpo ọkụ asphalt, kamakwa gbasaa ngwa akporo nke asphalt, emulsified asphalt emepela ngwa ngwa.

Asphalt emulsifier bụ ụdị surfactant. Ọdịdị kemịkalụ ya nwere otu lipophilic na hydrophilic. Ọ nwere ike adsorbed na interface n'etiti asphalt ahụ na mmiri, si otú budata mbenata free ike nke interface n'etiti asphalt na mmiri, na-eme ka ọ a surfactant na Nleta a edo na anụ emulsion.

Surfactant bụ ihe nwere ike ibelata elu erughị ala nke mmiri mgbe agbakwunyere na obere ego, ma nwee ike gbanwee njirimara interface na ọnọdụ nke usoro ahụ, si otú a na-emepụta wetting, emulsification, ụfụfụ, ịsacha, na mgbasa. , antistatic, lubrication, solubilization na usoro ọrụ iji mezuo ihe achọrọ nke ngwa bara uru.

N'agbanyeghị ụdị surfactant ọ bụla, molecule ya na-abụkarị akụkụ nke na-abụghị polar, hydrophobic na lipophilic hydrocarbon chain na polar, oleophobic na hydrophilic group. Akụkụ abụọ a na-adịkarị n'elu. Ngwunye abụọ nke molekul onye na-arụ ọrụ na-etolite nhazi asymmetric. Ya mere, usoro ihe omimi nke surfactant na-eji molecule amphiphilic nke bụ ma lipophilic na hydrophilic, ma nwee ọrụ nke ijikọ mmanụ na mmiri mmiri.

Mgbe surfactants gafere ụfọdụ ntinye na mmiri (mmetụta micelle dị oke mkpa), ha nwere ike ịmalite micelles site na mmetụta hydrophobic. Usoro emulsifier kacha mma maka emulsified asphalt dị ukwuu karịa itinye uche micelle dị oke egwu.
