Txoj Cai Ua Haujlwm ntawm Asphalt Modified Equipment

Asphalt Modified Equipment yog ib qho kev ua tiav kev siv tshuab ua ke nrog cua sov, pub mis, shearing, sib tsoo, nplawm, o thiab khaws cia. Nws txoj hauv kev ua haujlwm tseem ceeb nyob hauv kev hloov kho lub cev thiab fusion. Nrog rau cov neeg kho tshuab quab yuam pab los ntawm qhov kub thiab txias los ntawm cov tshuaj lom neeg, nws rhuav tshem cov qauv molecular ntawm lub hauv paus asphalt thiab hloov kho thiab txhawb kev sib sib zog nqus sib txuas ntawm ob theem kom ua kom lub cev zoo ntawm asphalt. Tag nrho cov txheej txheem suav nrog tsib theem ua ntu zus: kev kho ua ntej, pub mis thiab kev sib xyaw ua ntej, shearing-sib tsoo, qhov kub thiab txias swelling maturation thiab siab-stabilized cia-thiab-tso tawm. Kev sib koom tes ntawm txhua tus txheej txheem ua tiav kev hloov kho asphalt.
Thawj theem yog asphalt pre-kho, lub hauv paus ntawm kev hloov kho. Ntawm qhov kub thiab txias, lub hauv paus asphalt muaj nyob hauv cov kua los yog kua nplaum heev thiab tsis tuaj yeem sib xyaw ncaj qha nrog cov hloov pauv. Lub tshuab cua sov ntawm Asphalt Modified Equipment heats base asphalt nyob rau hauv qhov tseeb-kub tswj, feem ntau nyob rau hauv 160-180℃raws li asphalt qib. Asphalt softens txaus nrog txo viscosity thiab txhim kho kev ua haujlwm molecular. Kev tswj qhov kub thiab txias ntawm lub sijhawm tiv thaiv asphalt aging tshwm sim los ntawm overheating thiab tsis txhob muaj viscosity ntau dhau los ntawm cov cua sov tsis txaus, npaj cov khoom tsim nyog rau kev hloov pauv tom qab dispersion thiab fusion.
Qhov thib ob theem npog meej proportioning pub thiab ua ntej sib tov. Kev ntsuas tsis siv neeg thiab kev pub mis ntsuas lub hauv paus asphalt, SBS modifiers, roj hmab hmoov, stabilizers thiab dispersants kom raug raws li preset qauv kom tshem tawm qhov sib txawv ntawm qhov sib txawv. Modifiers yog pub tusyees mus rau hauv softened asphalt ntawm cov khoom siv kaw. Lub caij no, qis-ceev nplawm pib faib cov khoom hloov pauv ua ntej hauv asphalt thiab tiv thaiv agglomeration, txo qis kev ua haujlwm nyuaj rau kev sib tsoo thiab sib tsoo thiab ua tiav thawj homogenization.
Qhov thib peb theem yog core shearing thiab sib tsoo, qhov kev txiav txim siab txuas rau kev hloov kho. Cov ntaub ntawv sib xyaw ua ntej ntws mus rau hauv high-speed shear-sib tsoo units. High-speed rotors thiab precision stators tsim muaj zog shearing, tearing thiab sib tsoo los. Kev hloov pauv loj yog txiav, crushed thiab ua kom zoo dua qub los ntawm millimeter-scale mus rau micrometer-scale. Mechanical quab yuam cuam tshuam kev hloov pauv agglomerates thiab thawj asphalt molecular qauv kom muaj kev sib cuag txaus thiab permeation ntawm ob qhov nruab nrab sib txawv. Qhov no daws cov kev sib raug zoo tsis zoo thiab cov kev pheej hmoo ntawm kev sib cais thiab tsim cov khoom sib xyaw ua ke, uas yog qhov tseem ceeb rau kev ua haujlwm ruaj khov-asphalt.
Qib plaub yog qhov kub thiab txias tsis tu ncua. Cov ntaub ntawv tom qab shearing thiab sib tsoo tsis yog cov khoom kawg. Lawv raug xa mus rau hauv kev mob siab rau kev sib xyaw ua ke tso tsheb hlau luam rau kev txhawb nqa qis-ceev nplawm thiab txuag hluav taws xob. Thaum lub sij hawm no, refined modifier particles nqus lub teeb Cheebtsam los ntawm asphalt txaus, ua tiav o tshwm sim, stretch molecular chains thiab tsim cross-links los tsim ruaj khov peb-dimensional network lug ua ke nrog asphalt. Cov yam ntxwv ntawm lub cev ntawm cov asphalt dawb yog cov hauv paus txhim kho nrog txhim kho kev ruaj ntseg, kev sib koom ua ke muaj peev xwm thiab deformation tsis kam. Lub sijhawm o yog hloov kho raws li kev hloov kho pawg kom lav cov kev cuam tshuam zoo thiab zam kev sib cais tom qab theem thiab sib cais ntawm cov khoom tiav.
Qhov thib tsib theem yog siab-stabilized cia thiab tso tawm. Tom qab dhau kev soj ntsuam kev ua tau zoo, cov paub tab hloov asphalt raug xa mus rau qhov ntsuas kub tsis tu ncua hauv lub tank ruaj khov. Tank tuav maj mam nplawm tas li kom khaws cov khoom sib xws thiab tiv thaiv kev sib cais zoo li qub. Cov ntaub ntawv raug tso tawm tsis tu ncua raws li kev tsim kho xav tau nrog qhov ntsuas kub thiab qhov siab thoob plaws, kom ntseeg tau tias zoo ib yam ntawm cov khoom siv. Tag nrho cov Asphalt Modified Equipment ua haujlwm nrog kev sib txuas tsis siv neeg thiab ua tiav kev hloov kho hauv lub voj kaw los ntawm cov khoom siv raw khoom ua ntej kho kom tiav cov khoom tiav thiab lav cov khoom tsim nyog thiab ruaj khov.
