Gutera vuba vuba reberi ya asfalt itagira amazi adafite amazi. Niba diaphragm itabungabunzwe neza nyuma yo gutera, amazi ntizashira burundu, kandi umwuka mwinshi mwinshi uzagaragara mugihe cyo guteka ubushyuhe bwinshi, bikaviramo kunanuka kwa firime idafite amazi, hamwe no kutagira amazi meza, kurwanya ruswa, no kurwanya ikirere. . Kuberako ibidukikije byokubungabunga ahazubakwa ubusanzwe bidashobora kugenzurwa, ni ngombwa kunoza ubushyuhe bwo hejuru bwo gutera imiti yihuta yihuta ya reberi ya asfalt yangiza amazi atabigenewe.
Amazi ya elegitoronike ya selulose ether yatoranijwe kugirango arusheho guhangana nubushyuhe bwo hejuru bwibikoresho byatewe na rubber asfalt byihuse. Muri icyo gihe, ubushakashatsi bwakozwe ku ngaruka z'ubwoko n'ubwinshi bwa selulose ether ku miterere ya mashini, imikorere yo gutera, kurwanya ubushyuhe no kubika imiti yihuta yihuta ya reberi asifalt idafite amazi. Ingaruka.
Icyitegererezo
Kunyunyuza hydroxyethyl selulose mumazi ya 1/2 ya deionised, koga kugeza bishonge burundu, hanyuma ushyiremo emulifisiyeri na hydroxide ya sodium mumazi asigaye ya 1/2 ya deionion hanyuma ukangure neza kugirango utegure igisubizo cyisabune, hanyuma, kuvanga ibyavuzwe haruguru Ibisubizo byombi ni iringaniye kugirango ibone igisubizo cyamazi ya hydroxyethyl selulose, kandi agaciro kayo pH igenzurwa hagati ya 11 na 13.
Kuvanga asifalt emulisifike, neoprene latex, hydroxyethyl selulose yumuti wamazi, defoamer, nibindi ukurikije igipimo runaka kugirango ubone ibikoresho A.
Tegura kwibanda kuri Ca (NO3) 2 igisubizo cyamazi nkibikoresho B.
Koresha ibikoresho bidasanzwe byo gutera amashanyarazi kugirango utere ibikoresho A nibikoresho B ku mpapuro zisohora icyarimwe, kugirango ibyo bikoresho byombi bishoboke kandi bihita bishyirwa muri firime mugihe cya atomisiyonike.
Ibisubizo n'ibiganiro
Hydroxyethyl selulose ifite viscosity ya 10 000 mPa · s na 50 000 mPa · s yaratoranijwe, hanyuma hajyaho uburyo bwo kongeramo nyuma yo kwiga ingaruka ziterwa nubukonje ndetse n’inyongera ya hydroxyethyl selulose kumikorere yo gutera vuba vuba. reberi ya asfalt idafite amazi, ibikoresho byo gukora firime, kurwanya ubushyuhe, ibikoresho bya mashini hamwe nububiko. Mu rwego rwo kwirinda kwangirika kwuburinganire bwa sisitemu yatewe no kongeramo hydroxyethyl selulose yumuti, bikavamo demulisiyasi, emulisiferi hamwe na pH bigenga pH mugihe cyo gutegura hydroxyethyl selulose.
Ingaruka za Viscosity ya Hydroxyethyl Cellulose (HEC) kuri Gutera no Gukora Filime Ibyiza byo Kwirinda Amazi
Iyo ubwinshi bwa hydroxyethyl selulose (HEC), niko bigira ingaruka kumiti yo gutera no gukora firime yimyenda idafite amazi. Iyo amafaranga yiyongereyeho ari 1 ‰, HEC ifite viscosity ya 50 000 mPa · s ituma ubwiza bwa sisitemu yo gutwikira amazi Iyo bwiyongereyeho inshuro 10, gutera biragoye cyane, kandi diaphragm iragabanuka cyane, mugihe HEC ifite ububobere. ya 10 000 mPa · s ntacyo igira ku gutera, kandi diaphragm igabanuka mubisanzwe.
Ingaruka za Hydroxyethyl Cellulose (HEC) ku Kurwanya Ubushyuhe bwo Kwirinda Amazi
Gutera vuba vuba reberi ya asfalt yamazi yatewe amazi yatewe ku rupapuro rwa aluminiyumu kugira ngo hategurwe icyitegererezo cy’ibizamini byo kurwanya ubushyuhe, kandi yarakize hakurikijwe uburyo bwo gukiza bw’amazi asfalt y’amazi adashingiye ku mazi ateganijwe mu rwego rw’igihugu GB / T 16777- 2008. Hydroxyethyl selulose ifite viscosity ya 50 000 mPa · s ifite uburemere buke bwa molekile. Usibye gutinda guhumeka kw'amazi, inagira n'ingaruka runaka yo gushimangira, bigatuma bigora amazi guhinduka imbere yimbere, bityo bizabyara ibinini binini. Uburemere bwa molekuline ya hydroxyethyl selulose ifite ubwiza bwa 10 000 mPa · s ni nto, idafite ingaruka nke ku mbaraga zibikoresho kandi ntibigira ingaruka ku ihindagurika ry’amazi, bityo rero nta gisekuru kibaho.
Ingaruka yubunini bwa hydroxyethyl selulose (HEC) yongeyeho
Hydroxyethyl selulose (HEC) ifite ubwiza bwa 10 000 mPa · s yatoranijwe nkikintu cy’ubushakashatsi, kandi hasuzumwe ingaruka z’inyongera zitandukanye za HEC ku mikorere yo gutera no kurwanya ubushyuhe bw’imyenda idafite amazi. Urebye imikorere yo gutera, kurwanya ubushyuhe hamwe nubukanishi bwibikoresho bitarinda amazi byuzuye, bifatwa ko urugero rwiza rwa hydroxyethyl selile ari 1 ‰.
Neoprene latex muri spray yihuta-gushiraho reberi ya asfalt itagira amazi hamwe na asfalt ya emulisile ifite itandukaniro rinini muburinganire nubucucike, biganisha ku gusenya ibintu A mugihe gito mugihe cyo kubika. Kubwibyo, mugihe cyo kubaka ahakenewe bigomba gukangurwa neza mbere yuko bitera, bitabaye ibyo bikazana impanuka zoroshye. Hydroxyethyl selulose irashobora gukemura neza ikibazo cyo gusiba cyatewe na rubber asfalt yihuta. Nyuma yukwezi kumwe kubika, haracyari delamination. Ubukonje bwa sisitemu ntabwo buhinduka cyane, kandi ituze ni ryiza.
kwibanda
1) Nyuma ya hydroxyethyl selulose yongewe kumashanyarazi yihuta yihuta ya reberi asifalt yamazi, irwanya ubushyuhe bwamazi adafite amazi aratera imbere cyane, kandi ikibazo cyibibyimba byinshi hejuru yubuso biratera imbere cyane.
)
3) Kwiyongera kwa hydroxyethyl selulose itezimbere ububiko bwokubika kwa rubber asfalt yihuta yihuta, kandi nta gusiba bibaho nyuma yo kubikwa ukwezi.
