Kupopera msanga-kukhazikitsa mphira phula asphalt madzi zokutira ndi zokutira madzi. Ngati diaphragm sichisamalidwa bwino pambuyo popopera mankhwala, madzi sangasinthe nthunzi, ndipo mpweya wowuma umawonekera mosavuta pakawotcha kwambiri, zomwe zimapangitsa kuti filimuyo isalowe m'madzi, ndi kusalowa madzi, anti-corrosion, ndi nyengo. . Chifukwa malo osungiramo malo omangawo nthawi zambiri amakhala osalamulirika, ndikofunikira kuwongolera kutentha kwapamwamba kwa zokutira zothira madzi za mphira wa asphalt wokhazikika potengera momwe amapangidwira.
Madzi sungunuka mapadi ether anasankhidwa kusintha kutentha kukana kwa sprayed mwamsanga-akhazikike mphira phula zinthu zotchinga madzi. Panthawi imodzimodziyo, zotsatira za mtundu ndi kuchuluka kwa cellulose ether pazinthu zamakina, kupopera mbewu mankhwalawa, kukana kutentha ndi kusungirako kupopera mbewu mankhwalawa mwamsanga-kukhazikitsa mphira phula phula zokutira madzi anaphunzira. magwiridwe antchito.
Kukonzekera kwachitsanzo
Sungunulani hydroxyethyl cellulose mu 1/2 madzi deionized, yambitsani mpaka itasungunuka kwathunthu, kenaka yikani emulsifier ndi sodium hydroxide kwa otsala 1/2 madzi deionized ndi kusonkhezera mofanana kukonzekera sopo yankho, ndipo potsiriza, sakanizani pamwamba Njira ziwirizi ndi. wosakanikirana wosakanikirana kuti apeze yankho lamadzi la hydroxyethyl cellulose, ndipo pH yake imayendetsedwa pakati pa 11 ndi 13.
Sakanizani emulsified asphalt, neoprene latex, hydroxyethyl cellulose aqueous solution, defoamer, etc. molingana ndi chiŵerengero china kuti mupeze zakuthupi A.
Konzani ndende ina ya Ca(NO3)2 yankho lamadzi ngati B.
Gwiritsani ntchito zida zapadera zopopera mankhwala kuti mupozere zinthu A ndi zinthu B papepala lotulutsa nthawi imodzi, kuti zida ziwirizi zilumikizidwe ndikuyika filimu mwachangu pakadutsa njira ya atomization.
Zotsatira ndi zokambirana
Hydroxyethyl mapadi ndi mamasukidwe akayendedwe a 10 000 mPa · s ndi 50 000 mPa · s anasankhidwa, ndipo njira pambuyo kuwonjezera anatengera kuphunzira zotsatira za mamasukidwe akayendedwe ndi kuwonjezera kuchuluka kwa hydroxyethyl mapadi pa kupopera ntchito ntchito mofulumira-kukhazikitsa. mphira phula phula zokutira madzi, Mafilimu kupanga katundu, kukana kutentha, makina katundu ndi katundu yosungirako. Pofuna kupewa kuwonongeka kwa dongosolo bwino chifukwa cha kuwonjezera pa hydroxyethyl cellulose njira, chifukwa demulsification, ndi emulsifier ndi pH regulator anawonjezedwa pokonza njira hydroxyethyl mapadi.
Mphamvu ya Viscosity ya Hydroxyethyl Cellulose (HEC) pa Kupopera ndi Kupanga Mafilimu Makhalidwe a Zopaka Zosalowa Madzi.
Kuchuluka kwa mamasukidwe akayendedwe a hydroxyethyl mapadi (HEC), m'pamenenso amakhudza kwambiri kupopera mbewu mankhwalawa ndi filimu kupanga katundu wa zokutira madzi. Pamene kuchuluka kwake kowonjezera ndi 1 ‰, HEC yokhala ndi mamasukidwe a 50 000 mPa·s imapangitsa kukhuthala kwa dongosolo lopaka madzi lopanda madzi Pamene likuwonjezeka ndi nthawi 10, kupopera mbewu mankhwalawa kumakhala kovuta kwambiri, ndipo diaphragm imachepa kwambiri, pamene HEC ndi mamasukidwe akayendedwe. ya 10 000 mPa·s imakhala ndi mphamvu zochepa pa kupopera mbewu mankhwalawa, ndipo diaphragm imachepa mwachibadwa.
Mphamvu ya Hydroxyethyl Cellulose (HEC) pa Kulimbana ndi Kutentha kwa Zopaka Zosalowa Madzi
Chophimba chopanda madzi cha mphira wopopera mwachangu chinapopera pa pepala la aluminiyamu kuti chikonzekere kuyesa kukana kutentha, ndipo chinachiritsidwa molingana ndi machiritso a phula lopanda madzi lopangidwa ndi madzi lomwe lili mu muyezo wadziko lonse wa GB/T 16777- 2008. Ma cellulose a hydroxyethyl okhala ndi kukhuthala kwa 50 000 mPa·s ali ndi kulemera kwakukulu kwa molekyulu. Kuwonjezera pa kuchedwetsa kutuluka kwa madzi, kumakhalanso ndi mphamvu yolimbitsa thupi, zomwe zimapangitsa kuti madzi asasunthike kuchokera mkati mwa zokutira, choncho amatulutsa ziphuphu zazikulu. Maselo a cellulose a hydroxyethyl cellulose okhala ndi mamasukidwe a 10 000 mPa·s ndi ang'onoang'ono, omwe amakhala ndi mphamvu pang'ono pa mphamvu ya zinthuzo ndipo samakhudza kuphulika kwa madzi, kotero palibe kuwira kwa m'badwo.
Zotsatira za kuchuluka kwa cellulose ya hydroxyethyl (HEC) yowonjezeredwa
Hydroxyethyl cellulose (HEC) yokhala ndi viscosity ya 10 000 mPa·s inasankhidwa ngati chinthu chofufuzira, ndipo zotsatira za zowonjezera zosiyana za HEC pa ntchito yopopera mankhwala ndi kukana kutentha kwa zokutira zopanda madzi zinafufuzidwa. Poganizira kupopera mbewu mankhwalawa ntchito, kutentha kukana ndi katundu makina a zokutira madzi mokwanira, amaona kuti mulingo woyenera kwambiri Kuwonjezera kuchuluka kwa hydroxyethyl mapadi ndi 1 ‰.
The neoprene latex mu sprayed mwamsanga-kukhazikitsa mphira phula zokutira madzi ndi phula emulsified ali ndi kusiyana kwakukulu polarity ndi kachulukidwe, amene amatsogolera delamination zinthu A mu nthawi yochepa posungira. Choncho, pomanga pa malo Imafunika kugwedezeka mofanana isanapopedwe, apo ayi izo zingayambitse ngozi zabwino. Ma cellulose a Hydroxyethyl amatha kuthana ndi vuto la delamination la zokutira zopanda madzi za rabara zokhazikika zokhazikika. Pambuyo pa mwezi umodzi yosungirako, palibe delamination. The mamasukidwe akayendedwe a dongosolo si kusintha kwambiri, ndipo bata ndi zabwino.
kuganizira
1) Pambuyo pakuwonjezedwa kwa cellulose ya hydroxyethyl ku zokutira zothira mphira zokhazikika mwachangu, kukana kwa kutentha kwa zokutira kopanda madzi kumakhala bwino kwambiri, ndipo vuto la thovu wandiweyani pamwamba pa zokutira limakula kwambiri.
2) Pansi pa zomwe sizimakhudza kupopera mbewu mankhwalawa, kupanga mafilimu ndi zinthu zamakina, cellulose ya hydroxyethyl inatsimikiziridwa kukhala hydroxyethyl mapadi ndi mamasukidwe akayendedwe a 10 000 mPa · s, ndipo kuchuluka kwake kunali 1 ‰.
3) Kuphatikizika kwa cellulose ya hydroxyethyl kumapangitsa kukhazikika kosungirako kwa mphira wopopera mwachangu wopaka phula, ndipo palibe delamination yomwe imachitika ikasungidwa kwa mwezi umodzi.
