Zvakajairika kuti jecha nematombo zvive nedhaka, uye hazvizove nekukanganisa kukuru pakuita kwekongiri.Nekudaro, yakawandisa madhaka emukati anozokanganisa zvakanyanya kuyerera, plastiki uye kusimba kwekongiri, uye kusimba kwekongiri kuchaderedzwawo.Madhaka ari mujecha nematombo anoshandiswa mune dzimwe nzvimbo akakwira kusvika pa7% kana kutopfuura 10%.Mushure mekuwedzera admixtures, kongiri haigone kuita kwakaringana kuita.Iyo kongiri haina kana fluidity, uye kunyange zvishoma fluidity ichanyangarika munguva pfupi.Nzira huru yechiitiko chiri pamusoro apa ndechokuti ivhu riri mujecha rine adsorption yakanyanyisa, uye yakawanda yezvisanganiswa zvichange zvichishambadzirwa nevhu mushure mekusanganiswa, uye zvakasara zvakasanganiswa hazvina kukwana kushambadzira uye kuparadzira zvimedu zvesimende.Parizvino, polycarboxylate admixtures ave kushandiswa zvakanyanya.Nekuda kwehudiki hwechigadzirwa ichi, chiitiko chiri pamusoro apa chakanyanya kuoma kana chinoshandiswa kugadzira kongiri ine yakakwirira yedhaka nejecha.

Parizvino, tsvakurudzo yakadzama iri kuitwa pamatanho ekugadzirisa kongiri yedhaka kuramba.Mishonga mikuru ndeiyi:

(1) Wedzera dosage ye admixtures.Kunyangwe iyi nzira ine mhedzisiro yakajeka, nekuti iyo dosage ye admixtures mukongiri inoda kupetwa kaviri kana kupfuura, mutengo wekugadzira kongiri unowedzera.Zvakaoma kuti vagadziri vabvume.

(2) Kemikari shanduko yemusanganiswa unoshandiswa kushandura chimiro che molecular ye admixture.Kune mishumo yakawanda ine hukama, asi munyori anonzwisisa kuti izvi zvichangobva kugadzirwa anti-mud additives zvichiri kuchinjika kune ivhu rakasiyana.

(3) Kugadzira rudzi rutsva rwe-anti-sludge functional admixture kuti ishandiswe pamwe chete neanowanzo shandiswa admixtures.Isu takaona kunze kwenyika anti-sludge agent muChongqing neBeijing.Chigadzirwa chacho chine muyero mukuru uye mutengo wakakwirira.Izvo zvakare zvakaoma kune general commercial kongiri mabhizinesi kugamuchira.Mukuwedzera, chigadzirwa ichi chinewo dambudziko rekugadzirisa kune ivhu rakasiyana.

 

Aya anotevera anti-mud matanho aripo zvakare ekutsvaga kutsvaga:

1.Iyo inowanzoshandiswa admixtures inosanganiswa nezvinhu zvine imwe dispersibility uye mutengo wakaderera kuti uwedzere zvikamu zvinogona kudsorbed nevhu, iro rine chimwe chiitiko.

2.Kubatanidza imwe huwandu hwemvura-inonyungudika yakaderera-molecular-huremu polymer mune admixture kune imwe mhedzisiro.

3.Shandisa zvimwe zvinorasa, zvinodzoreredza uye zvinoderedza mvura izvo zvinowanzobuda ropa.
