Kafukufuku wokhudza kuyeretsedwa ndi kubwezerezedwanso kwa nsangalabwi pokonza madzi onyansa

Panthawi yokonza miyala ya marble ndi miyala ina, madzi otayira omwe amapangidwa amakhala ndi ufa wambiri wamwala ndi woziziritsa. Ngati madzi oipawa atayidwa mwachindunji, sizidzangowononga madzi okha, komanso kuwononga kwambiri chilengedwe. Kuthetsa vutoli, ena mwala processing ogwira utenga mankhwala mpweya njira, pamodzi polyaluminium kolorayidi (PAC) ndi polyacrylamide (PAM), pamodzi ndizida zosindikizira zosefera, kuti akwaniritse chithandizo chothandiza komanso kubwezeretsanso zinyalala, ndikupanga phindu lina lazachuma.

1, Makhalidwe ndi zovuta mankhwala a zimbudzi

Marble processing madzi zinyalala ali makhalidwe a mkulu inaimitsidwa zolimba ndende ndi zikuchokera zovuta. Tinthu tating'ono ta ufa wamwala ndizovuta kukhazikika mwachilengedwe, ndipo choziziritsa kukhosi chimakhala ndi mankhwala osiyanasiyana monga ma surfactants, rust inhibitors, ndi zina zambiri, zomwe zimawonjezera vuto lakuthira madzi oyipa. Ngati sichikonzedwa bwino, zolimba zotayidwa m'zimbudzi zimatsekereza mapaipi, ndipo mankhwala oziziritsa kukhosi amawononga nthaka ndi madzi.

2, Zosefera atolankhani processing otaya

Kampaniyo yayika makina osindikizira ochita bwino kwambiri m'makina ochotsa zimbudzi. Choyamba, kuwonjezera polyaluminium kolorayidi ndi polyacrylamide mu dosing ndowa anapereka ndi fyuluta atolankhani, ndi kupasuka ndi kusonkhezera iwo mu gawo lina. Mankhwala osungunuka amayendetsedwa ndendende ndi pampu ya dosing kuti apereke ku tanki yosakanikirana ya makina osindikizira. Mu thanki yosanganikirana, mankhwalawo amasakanizidwa bwino ndi zimbudzi, ndipo coagulation ndi flocculation reactions zimachitika mofulumira. Pambuyo pake, madzi osakanikirana amalowa mu chipinda cha fyuluta cha makina osindikizira, ndipo pansi pa kupanikizika, madzi amatulutsidwa kudzera mu nsalu ya fyuluta, pamene sediment imatsekeredwa mu chipinda cha fyuluta. Pambuyo pa kusefera kwanthawi yayitali, keke yamatope yokhala ndi chinyezi chochepa imapangidwa, kukwaniritsa kulekanitsa koyenera kwa olimba ndi madzi.

Mwachidule, ntchito mankhwala mpweya njira, pamodzi polyaluminium kolorayidi ndi Polyacrylamide, ndi pamodzi ndi fyuluta atolankhani zipangizo kuchitira nsangalabwi processing madzi zinyalala ndi kothandiza, ndalama, ndi chilengedwe wochezeka njira ndi wabwino Kukwezeleza mtengo.

3, Kusankhidwa kwa atolankhani a fyuluta
