Mari yekusanganisa inoderedza mumiririri inodarika iyo yakajairika kusanganisa huwandu nekakati wandei, uye pesvedzero yayo mukuita kongiri inofanirwa kutsanangurwa maererano nemamiriro ezvinhu chaiwo.
Muchiitiko chekutanga, muUltra-yakakwira-simba kongiri, nekuti iyo mvura-binder ratio ndeye ≤0.3 kana yakaderera seye.2, inowanzo kuratidza kuti mamiriro ekongiri haina hanya nehuwandu hwemvura kuderedza mumiririri. Kuitira kuti uwane iyo yakakodzera fluidity nyika, mvura yacho yakaderedzwa. Iyo Dosage yemumiririri inowanzoitika 5-8 times iyo yakajairika dosage, ndiyo, iyo dosage yePolyarboxylic acidinoda kusvika 5% -8%. Kwekongiri kongiri pazasi c50, zvirimo zvakakwirira zvakakura zvinoshamisa. Nekudaro, iyo bvunzo inowana inoratidza kuti simba rekongiri pazera rimwe nerimwe rinokura zvakanaka pasi pehuwandu uhwu, uye simba rine simba rekongiri rakagadzirirwa neiyi simba rakakura kupfuura 100mpa.
Icho chikonzero ndechekuti: kupararira kwemvura kuderedza mumiririripane simende ingori chete kuyamwa muviri.Mvura kuderedza mumiriririMamolekyules anodhonza pamusoro pechisimba chemagetsi. Kuburikidza neSterion Princy uye Electrostatic Kudzora, chimiro chekutanga cheSpinement Scument inopararira uye mvura yemahara mvura inosunungurwa. , Nokudaro achiwedzera fluidity yekongiri, uye nekuda kweiyo nzvimbo yayo yakakosha yemubatanidzwa, iyoPolyarboxylic acidZvichienderanamvura kuderedza mumiriririinogona kudzivirira zvidimbu zvekusimbisa kubva pakunyorwazve mukati menguva yakati, saka ine yakanaka yekuchinjisa kuita. Kamwe imwe nguva yenguva yapfuura, iyo yeiyo hydration chigadzirwa ichaputira zvachosemvura kuderedza mumiriririmamorekuru adsorbed pamusoro pechisimba chekesi. Mushure memvura kuderedza mumiriririMamolekyules anochengetedzwa, kupararira kunonyangarika zvachose, uyezve haichazove nemhedzisiro kana pesvedzero pane kongiri. Iyo simendi inowanzo kuve nemvura simba rekunyora rinokura kazhinji.
Ehe, nekuda kwezvakakwirira zvemukatimvura kuderedza mumiririri, kusunganidzwa kwemvura kuderedza mumiriririmamorekuru mukongiri yakakura. Mushure memamwe mamorekuru akafukidzwa neiyo hydration zvigadzirwa, mamorekuru matsva anodhakwa pamusoro peiyo simende hydration zvigadzirwa, kudzivirira spinement zvigadzirwa kubva mukukurumidza kuwanda. Network inoumbwa, iyo inotambanudza nguva yekugara kune imwe nhanho, asi mamiriro emagetsi emagetsi haazopfuure 24h.
Mune yechipiri nyaya, iyomvura kuderedza mumiriririIcho pacharo ine zvimwe mhepo-yekupindira uye kudzoreredza zvivakwa, uye kakawanda zvekupedza-kufungidzira kunogona kuve nemhedzisiro yakakura mukuita kongiri. Kazhinji, huwandu hwekudzoreredza chikamu chakatemerwa maererano neyakaipisa mamiriro ekunze, zvinodikanwa zveinjiniya uye zvakajairika dosage yemvura kuderedza mumiririri. Adsorption inobata iyo yakajairika hydration yezvinyorwa zvekushandiswa. Muchiitiko chakareruka, nguva yekuedza iri kwenguva refu, uye mune yakaipisisa, kongiri haizogadzi kwemazuva akati wandei kana zvachose. Kazhinji. Ehezve, nekuti subway accluding mapaya (kazhinji 72-90h yekutanga kurongedza) uye misa yekuvakwa kongororo yakadai senheyo dzinotaridzika senheyo dzinenge dziripo, madhiri, etc., nguva refu yekugara inodiwa. Kazhinji, iro resimba rinofanira kuwedzerwa nenzira kwayo panguva yekugadzirwa kwemusanganiswa ratio. Ita shuwa kuti simba rinobva 28d rinosangana nezvinodiwa zvechimiro.
Mweya-wekupindiramvura kuderedza mumiriririsuper yakasanganiswa kakawanda. Kana mweya wemukati wekongiri zvakakodzera pane zvakajairika kusanganisa, izvo zvemhepo zvichawedzera kwazvo mushure mekunge super kusanganisa kakawanda. Iyo kongiri slurry haina kupfuma zvisina kujairika, uye kongiri inokwenenzverwa uye ichiyambuka painenge yakadhinda, iyo yakakomba apo kongiri yakasununguka uye yakasvibirira sechingwa chesimba, simba redzimhosva.
Mune yechitatu nyaya, kunyangwe kanamvura kuderedza mumiriririIchochocho hachina mhepo-yekupindira uye yekudzosera mhando, mushure mekupindwa kaviri, kana mvura yadhindwa isina kugadziridzwa munguva, kushanda kweiyo nyowani kongiri kunogona kuora mwoyo zvakanyanya, zvichikonzera mungano wakakura. Mvura, kusarudzika, pasi pekunyepedzera, kuomesa, nezvimwewo, uye kusasimba kwemukati mushure mekukura kwemvura-kune-binder chiyero chakakomberedza chesimbi bar, uye kuderera kwesimba , iyo inoita kuti ibar rebara raive rakanyanya kudonha. Hukuru hwekubuda ropa zvakakonzerwa nekukasira kuonekawo pamusoro pekongiri uye zvikamu zvinosangana neyekugadzika musimba rezvikamu izvi, uye huwandu hukuru hwekuremara senge marara. honeycomps, uye nzvimbo dzekunyepedzera dzinowanzo kuoneka kana iyo mold ichibviswa, iyo inoita kuti kugona kurambe nekudzikisira kwekunze kuderedza zvakanyanya, zvakanyatsoita basa rekusimba kwe kongiri.
