Anoyevedza asphalt ari emulsion akaumbwa neasphalt akapararira mumvura. Mvura iri mazviri inongova svikiro mune asphalt. Mushure mekunge asphaled asphalt yasanganiswa kana kusanganiswa, inoputsa emulsion uye mvura iri mune inokwira asphalt anoputika. Chiyero chemvura kuenda kuasphalts mune inoyevedza asphalts haina kungoita zvekugadzira uye zvekufambisa zvinokonzeresa asphalt, asi zvakare zvine chekuita nekuchengetera kugadzikana, viscosity nezvimwe zviratidzo zvechipuspfaed asphalts. Naizvozvo, zvakafanira kuyedza iyo Asphalt yezvinyorwa mune inozwa asphalts.
Kuti vaone zvemukati zvehupanhasi mune inozwa asphalts, asphaled asphalt inoda kuti isvibiswe. Nekudaro, nyika dzakasiyana nemasangano zvine nzira dzakasiyana dzekurara dzinopindirwa asphalts. Mukupfupikisa, pane nzira ina huru: Distillation, ovheni yekuvira, yakananga kupisa nekuvhurwa nekucheka kwechisikigo.

1. Nzira distillation
Nzira dzinonyanya kumiririra nzira dzekupindirana ndidzo nzira yeAstm muUnited States, iyo yakaderera-tembiricha yekudziya nzira, uye nzira dzakashata dzinoshandiswa kudziya kwakasiyana uye nguva dzakashata dzaishandiswa muUnited States kuUnited States.
(1) ASTM Distility nzira. United States Astm D244-00 inomutsa nzira nhatu dzekubvisa dzinodzora rasara: zvakasara uye nemafuta nekuputika, uye akaderera-tembiricha (135 ° C) vacuum distillation. Iyo ASTM Distilation nzira ndeyekudurura 200g yekukaswa inoshandurwa Iyo yakasara yakawanikwa nenzira iyi inogona zvakare kushandiswa kuyedza zvinhu zveasphalation yakasara.
(2) ASTM yakaderera-tembiricha vacuum distillation nzira. Kufunga kuti vamwe vanogumisa asfirlts, kunyanya kugadziridzwa anodzikiswa, zvivakwa zveSisphalial asphalt zvakawanikwa zvakanyanya uye hazvigoni kuratidza mamiriro chaiwo ehusiphofeti panguva yekushandisa. Naizvozvo, yakadzika-tembiricha yekumanikidza nzira yakawedzerwa kune iyo 2000 edition yeASTM D244. Iyi nzira inoshandisa chiridzwa uye kuregedzwa pa135 ° C kwemaminetsi makumi matanhatu.
. Nyika dzakawanda muUnited States dzinoshandisa bvumirano kuti uwane kupindurwa kwemaminitsi,
2. Oven Equisoration nzira
Mazhinji mamiririri anomiririra ndiyo nzira yeASTM Eveve uye nzira yeCalifornia, USA.
Iyo ASTM Ereation nzira ndeye kutora mana anowana neyekugona kwe1000m zvakasara.
Nzira iyo muCalifornia, USA kutora 40G yeEpphals spphalt, chiichengete pa118 Iyo yakasara yakasara inogadzirwa mune yakakodzera bvunzo fungidziro kuyera iyo index.

Ose maviri Japan uye nyika yangu shandisa nzira iyi. Muedzo weiyo eversion yakasara sepfulassified asphalts munyika yangu ndeyekupisa uye kufambisa 300G yemvura ye20-30min yakachenesa, tobva takura Iyi nzira yekuedzwa yakaumbwa nezvinongedzera kune zviyero zveJapan.
Uye zvakare, kuti uwane huwandu hwesphalt kumvura mune inoyevedza asphalt, inogona kuwanikwa chete nekuona iyo Asphalt yehusipholtified, asi zvakare nekuona zvinhu zvemvura mune asphalassified asphalt. ASTM D244-00 zvakare ine nzira yekuedzwa yezvinhu zvemvura mune inozwa asphalt.
Izvo zvakasara zvemukati uye zvivakwa zvinowanikwa nenzira dzakasiyana dzekuwana asphalial asphalt dzakasiyana.
Kutsvaga kwekuedza kwakawana kuti nzira yekuomesa mune oveni kwenguva yakati kazhinji inoguma nekubuda kwemvura; Iyo ASTM Distilation bvunzo yakagadziriswa, asi nekuda kwemidziyo yakaomesesa bvunzo, iri kuoma kusimudzira munyika yangu. Kunyangwe nzira yenyika yangu yekushivirira zvakananga kusvika 163 ° C kuwana zvasara zvichakanganiswa nezvinhu zvevanhu, nzira iri nyore, mhedzisiro yebvunzo yakavimbika, uye inogoneka.
