Gutera irangi ritaziba mu buryo bwihuse ni irangi rishingiye ku mazi. Iyo diaphragm idafashwe neza nyuma yo gutera irangi, amazi ntabwo azashira burundu, kandi ibibyimba by'umwuka binini bizagaragara byoroshye mu gihe cyo guteka mu bushyuhe bwinshi, bigatuma agace kadaziba kagabanuka, kandi amazi ntaziba, kandi ntaziba, ndetse n'ikirere. Kubera ko imiterere y'ibidukikije byo kubungabunga aho bubaka akenshi idagenzurwa, ni ngombwa kunoza irangi ritaziba mu bushyuhe bwinshi riterwa irangi ritaziba mu buryo bwihuse ukurikije uburyo bwo gukora.
Eteri ya selulosi ishongeshwa mu mazi yatoranijwe kugira ngo yongere ubushyuhe bwinshi bw'ibikoresho bya asphalt ya rubber ishyirwamo amazi vuba. Muri icyo gihe, ingaruka z'ubwoko n'ingano ya eteri ya selulosi ku miterere ya mashini, imikorere yo gutera, ubushyuhe no kubika irangi ritanyereza amazi rya asphalt ya rubber ishyirwamo amazi vuba zakoreweho ubushakashatsi.
Icyitegererezo cyo gutegura
Shyiraho hydroxyethyl cellulose mu 1/2 cy'amazi yakuwemo ayoni, uvange kugeza ishongeshejwe burundu, hanyuma ongeramo emulsifier na sodium hydroxide ku 1/2 cy'amazi yakuwemo ayoni hanyuma uvange neza kugira ngo utegure umuti w'isabune, hanyuma uvange ibivuzwe haruguru. Ibi bisubizo byombi bivange neza kugira ngo ubone umuti w'amazi wa hydroxyethyl cellulose, kandi agaciro ka pH kayo kagenzurwa hagati ya 11 na 13.
Vanga asphalt ya emulsified, neoprene latex, hydroxyethyl cellulose aqueous solution, defoamer, nibindi hakurikijwe igipimo runaka cyo kubona ibikoresho A.
Tegura igipimo runaka cya Ca (NO3)2 cy'amazi nk'ikintu cya B.
Koresha ibikoresho byihariye byo gutera umuti mu gutera umuti A n'ibikoresho B ku rupapuro rwo kurekura umuti icyarimwe, kugira ngo ibyo bikoresho byombi bishobore gukorwaho kandi bishyirwe mu buryo bwihuse mu gihe cyo gutera umuti.
Ibisubizo n'ibiganiro
Hatoranijwe selulose ya Hydroxyethyl ifite ubukana bwa mPa 10.000 na mPa 50.000, kandi uburyo bwo kongeramo bwakoreshejwe kugira ngo higwe ingaruka z'ubukana n'ingano ya hydroxyethyl cellulose ku mikorere yo gutera imiti ya asphalt idapfa gukoreshwa vuba, imiterere yo gukora filime, ubushobozi bwo kwirinda ubushyuhe, imiterere ya mekanike n'imiterere yo kubika. Kugira ngo hirindwe kwangirika kw'uburinganire bw'imikorere buterwa no kongeramo umuti wa hydroxyethyl cellulose, bigatuma habaho demulsification, hongewemo emulsifier na pH regulator mu gihe cyo gutegura umuti wa hydroxyethyl cellulose.
Ingaruka z'ubukana bwa Hydroxyethyl Cellulose (HEC) ku miterere yo gutera no gukora filime y'imyenda idakingwa n'amazi
Uko ubushyuhe bwa hydroxyethyl cellulose (HEC) burushaho kuba bwinshi, ni ko ingaruka ku miterere yo gutera no gushushanya irangi ritaziba amazi ziyongera. Iyo ingano yayo yongeweho ari 1‰, HEC ifite ubushyuhe bwa 50 000 mPa·s ituma ubushyuhe bwa sisitemu yo gutera amazi burushaho kuba bwiza Iyo yongereweho inshuro 10, gutera imiti biragorana cyane, kandi diaphragm iragabanuka cyane, mu gihe HEC ifite ubushyuhe bwa 10 000 mPa·s ntacyo igira ku gutera imiti, kandi diaphragm igabanuka mu buryo busanzwe.
Ingaruka za Hydroxyethyl Cellulose (HEC) ku bushyuhe burwanya irangi ritazi amazi
Igitambaro cya asphalt kidapfa gushonga cyatewe ku rupapuro rwa aluminiyumu kugira ngo gitegure ikizamini cyo kwirinda ubushyuhe, kandi cyavuwe hakurikijwe uburyo bwo gushonga bw'igitambaro cya asphalt kidapfa gushonga gishingiye ku mazi nk'uko biteganywa n'amategeko ngengamikorere y'igihugu ya GB/T 16777-2008. Selulose ya hydroxyethyl ifite ubukana bwa mPa 50 000 ifite uburemere bunini bwa molekile. Uretse gutinda gushonga kw'amazi, inagira ingaruka zimwe na zimwe zo gukomeza, bigatuma bigora amazi gushonga imbere mu gitambaro, bityo ikazatanga uduce duto. Uburemere bwa molekile ya hydroxyethyl cellulose ifite ubukana bwa mPa 10 000 ni nto, ntacyo bigira ku mbaraga z'ibikoresho kandi ntibigira ingaruka ku guhindagurika kw'amazi, bityo nta gusohora ibibyimba.
Ingaruka z'ingano ya hydroxyethyl cellulose (HEC) yongewemo
Igikoresho cy’ubushakashatsi cyatoranijwe nk’ubushakashatsi, kandi ingaruka zitandukanye zo kongeramo HEC ku mikorere yo gutera no kwirinda ubushyuhe bw’imyenda idakoresha amazi. Hashingiwe ku mikorere yo gutera, kurwanya ubushyuhe n’imiterere ya mashini yo gutera amazi idakoresha amazi, bifatwa nk’aho ingano nziza ya hydroxyethyl cellulose yo gutera ni 1‰.
Latex ya neoprene iri mu gitambaro cy’amazi cya asphalt ya rubber quick-setting hamwe na asphalt ya emulsified bifite itandukaniro rinini mu miterere n’ubucucike, bigatuma ibikoresho A bitandukana mu gihe gito mu gihe cyo kubibika. Kubwibyo, mu gihe cyo kubaka ahantu hakorerwa ibizamini bigomba kuvangwa neza mbere yuko bishyirwamo, bitabaye ibyo byatera impanuka nziza. Hydroxyethyl cellulose ishobora gukemura neza ikibazo cyo kuvamo asphalt ya rubber quick-setting. Nyuma y’ukwezi kumwe bibitswe, nta kuvamo asphalt. Ubukana bw’uburyo ntabwo buhinduka cyane, kandi uburimbane ni bwiza.
kwibanda ku kintu
1) Nyuma yuko hydroxyethyl cellulose yongewe ku gipfundikizo cy’umukara cya asphalt gishyirwamo amazi vuba, ubushobozi bwo kwirinda ubushyuhe bw’igipfundikizo cy’amazi burarushaho kwiyongera, kandi ikibazo cy’uduheri twinshi ku buso bw’igipfundikizo kirarushaho kwiyongera cyane.
2) Hashingiwe ku gitekerezo cyo kutagira ingaruka ku mikorere yo gutera, imikorere yo gukora filime n'imiterere y'ibikoresho, hydroxyethyl cellulose byagaragaye ko ari hydroxyethyl cellulose ifite ubukana bwa 10 000 mPa·s, kandi umubare w'inyongera wari 1‰.
3) Kongeramo hydroxyethyl cellulose byongera uburyo bwo kubika neza irangi ritavamo amazi rya asphalt rishyirwamo vuba, kandi nta gutandukanya ibintu bibaho nyuma yo kubika mu gihe cy'ukwezi kumwe.
