Sand Precoat: nezinhlamvu, isicelo

A impahla ezifana isihlabathi, udlala indima ebalulekile ekwakhiweni. It is ukungezwa Izingxube ezihlukahlukene ezisetshenziswa womshini amabhlogo ngokhonkolo futhi izigqulo ngoba plasters. Ziqinisa le embankments nemigwaqo. Umkhiqizo ayengasetshenziselwa nje yemvelo, kodwa yokufakelwa.

Kuye ohlotsheni ukukhiqiza anesihlabathi isihlabathi, inkwali, emfuleni noma olwandle. Precoat (wageza) isihlabathi - i material imvelo okuhambisa amanzi. Kucishe ayiqukethe ngobumba itshe.

indlela zokukhiqiza

Umkhiqizo "knock out" a ingcindezi amanzi esikhulu Hydro ndlela, ukususa noma yiluphi udaba particulate. Kuba amancane futhi iyunifomu, okwandisa izinga layo. Kuze kube yimanje, isihlabathi anesihlabathi bayindlala kakhulu embonini yezokwakha.

Izici:

• izinhlayiya angaphandle ingxube akuyona ezingaphezu kuka-0.3%;
• Radioactivity ekilasini - lokuqala;
• compaction isilinganiso - 1,05-1,52;
• Coefficient eliphezulu filtration.

Anesihlabathi isihlabathi kungaba okuncane, naphakathi-grained futhi indawo-grained. Inani layo silinganiselwa 0.6 mm. Umbala kuxhomeke kulokho kungcola abakhona asendabeni. umbala White noma lemicu empunga elinamathela othini has a ehlanzekile asebenza ngebhethri isihlabathi. Uma luhlaza kunalokho onsundu ngokuphaphathekile noma abe phuzi, bukhona impahla yensimbi oxides.

isicelo

isihlabathi anesihlabathi esetshenziswa:

• womshini curbs, amakholomu, ukhonkolo izindandatho, amathayili kuvuleke;
• njengenhlangano izixazululo excipient;
• I-kokuqeda imisebenzi.

Sand emgodini precoat (wageza) has eziningi eziwusizo phezu ezivamile inkwali impahla (ezingahlanjiwe).

isithunzi

• Hhayi yakhiwa izinhlayiya zobumba (ngokungafani ezingahlanjiwe enkwalini, okuyinto eqala ufune).
• okuqukethwe akhishiwe zamatshe esikhulu emhlabeni.
• Azikho inclusions organic.
• Asikho isidingo zokuhlanzwa olwengeziwe.

Lokubaluleke kakhulu ekwakheni ukusetshenziswa zohlobo okumsulwa. Kukhona izindlela wokuhlanza impahla. Uma kudingeka ukugeza esincane umkhiqizo ke sieved namanzi zinikwa. Oku-isidingo ukunakekela isitsha okuzokwenziwa backfilled ingxube. Amanzi lishintshwa izikhathi eziningana, kuze impahla uhlanzekile.

Ungase futhi ukuthenga isihlabathi anesihlabathi, intengo okuyinto ephakeme seeded. inzuzo yakhe wukuthi nguye senihlungiwe kakade. Kukhona indlela yesintu ehlambulula ingxube. Thatha anezikhala metal welulela phezu uzimele. Okokuqala ingxube ukuthi sieved ngokusebenzisa esibukweni bese wageza isitsha.

Ngo ukwakhiwa kukhona imisebenzi ezidinga ukusetshenziswa zinhlayiya ezinkulu. Ukuze wenze lokhu, thatha uhlaka nge anezikhala of 5-10 mm. It isethwe nendawo phezu ngezitini (4-5 izicucu ku ikhona ngalinye). Mesh abami burlap. ingxube Ngenhla elachithwa, yokululama yayo, namanzi sidla ecindezelwa hose.

Ngezinye izikhathi asetshenziswa ekwakhiweni ingxube isihlabathi nge ukungcola komhlaba nezinye ukumiswa. Kuvumeleke ukuyisebenzisa, akudingi ukuthi umsebenzi wenziwa kuphela ukusetshenziswa kwezinto eziphinde zisebenziseke izinga. Ngokwesibonelo, kuyadingeka ukugcwalisa ingxenye ngaphezu komhlabathi noma umsele.

isicelo salo kokubili isihlabathi zemvelo kanye yokufakelwa. Kusukela izinga kuncike amandla imikhiqizo nodaka.
