A. mvura kuderedza mumiririri

Chimwe chezvakakosha kushandiswa kwemvura kuderedza mumvura kuti uderedze mvura yekunyepedzera uye nekuvandudza iyo fluidity yekuchengetedza mvura yekuchengetedza mvura isina kuchinjika, kuitira kuti uwane zvinodiwa pakufambisa kwekutakura uye kuvaka. Mvura zhinji inoderedza admixture ine dosage yakazara. Kana dosage yakadzika yadarika, iyo mvura yekuderedza mvura haizowedzera, uye kubuda ropa uye kusarurana zvichaitika. Iyo dosage yakakwana ine hukama neyakagadzirwa kongiri, uye kongiri yemusanganiswa.

 

1. Naphthalene Superpasticastizer

Naphthalene SuperpasticastizerInogona kukamurwa muzvigadzirwa zvepamusoro (NA2SE4.COMSOMS <3%) Iyo DOSAGE Rudzi rweNaphthalene Series Water Rester: Iyo poda ndeye 0.5 ~ 1.0% yeiyo siment misa; Zvinyorwa zvakasara zvemhinduro zvinowanzoitika Naphthalene akateedzana mvura kuderedza mhepo, uye haina chekuita nenguva yekugara. Inogona kuumbwa neSodium Gluconate, Shuwa, HydroxyCarboycarboylic Acid uye Salts, Citric Acdrarger, uye ine huwandu hwakakodzera hwekupinda mumiririri, kurasikirwa kwekutsvedza kunogona kudzorwa zvinobudirira. Iko kukanganisa kwekusanzwisisika kwekuderera kweNaphthalene Series Water kuderedza ndeyekuti zvirimo zveSodium Sulfate yakakura. Kana tembiricha yakaderera pane 15 ℃, sodium sulfate crystallization inoitika.

 

2. Polyarboxylicy acid yakakura kwazvo

Polyarboxylic acidKuedza kwemvura kunoonekwa sechizvarwa chitsva cheMvura yepamusoro-soro kugovera, uye vanhu vanogara vakachengeteka, vanoshanduka-shanduka pane tsika yetsika yemvura inogovera. Zviitiko zvekuita zvePolycarboxylic acid Mhando yekudzora mumiririri inonyanya kuratidzwa mu :.25% ~ Kupinda, uye kwakanyanya kuderera alkali yezvinyorwa.

Nekudaro, mukuita,Polyarboxylic acidMvura kuderedza ichasangana nezvimwe zvinetso, zvakadai se: 1. Kuderedza kwemvura kunoenderana nezvinhu zvisina kugadzirwa uye kusanganisa zvakaringana nejecha nematombo uye nemhando yemugodhi admyture; 2. Mvura ichideredza uye kutsvedza matsime anovimba zvakanyanya nedunhu remvura kuderedza mumiririri, uye zvakaoma kuchengetedza kutsvedza nepasi pasi; 3. Iko kushandiswa kwekusangana kwakanyanya kana yakakwirira simba kongiri ine huwandu hukuru hwechibvumirano, icho chinonzwisa tsitsi kwemvura, uye kushandurwa kudiki kwemvura kunogona kukonzera shanduko huru mukutsvedza; 4. Pane dambudziko rekuwirirana nemamwe marudzi emvura kuderedza vamiririri uye mamwe mahonje, kana kunyange pasina mapopiso; 5. Dzimwe nguva kongiri ine mvura yakakura yekubuda ropa, kupindirana kwakakura kwemhepo, uye yakakura uye yakawanda mabhuru; 6. Dzimwe nguva tembiricha shanduko inokanganisa mhedzisiro yePolyarboxylic acidmvura inobhadhara.

Zvinhu zvinokanganisa kuenderana kwesimendi uyePolyarboxylic acidMvura kuderedza: 1. Iyo chiyero cheC3A / C4AS uye C3S / C3S Kana zvirimo zvakakura kupfuura 8%, kurasikirwa kwekutsvedza kwekuwedzera kongiri; 2. Yakanyanya kuwanda kana idiki Alkali yezvinyorwa ichakanganisika kukanganisa kwavo; 3. Hunhu husina kunaka hwesimendi rekusimbisa huchakanganisawo kuwirirana kwevaviri; 4. Yakasiyana yeGypsum mafomu; 5. Yakanyanya tembiricha simende inogona kukonzera kukurumidza kuronga kana tembiricha ichidarika 80 ℃; 6. Simpt nyowani ine yakasimba midziyo yemagetsi uye kugona kwakasimba kutora mvura inobhadhara; 7. Nenzira yakatarwa nzvimbo yeiyo simende.
