Kafukufuku wokhudza kuyeretsa ndi kubwezeretsanso madzi otayira pogwiritsa ntchito miyala ya marble

Pakukonza miyala ya marble ndi zinthu zina zamwala, madzi otayidwa omwe amapangidwa amakhala ndi ufa wambiri wa miyala ndi choziziritsira. Ngati madzi otayidwa awa atulutsidwa mwachindunji, sadzangowononga madzi okha, komanso adzaipitsa chilengedwe kwambiri. Pofuna kuthetsa vutoli, kampani ina yokonza miyala imagwiritsa ntchito njira ya mankhwala, kuphatikiza polyaluminum chloride (PAC) ndi polyacrylamide (PAM), kuphatikizazida zosefera, kuti akwaniritse bwino ntchito yokonza ndi kubwezeretsanso zinyalala, komanso kuti apeze phindu lina pazachuma.

1, Makhalidwe ndi mavuto ochizira zinyalala

Madzi otayira omwe amakonzedwa ndi miyala ya marble ali ndi mawonekedwe a kuchuluka kwa zinthu zolimba zomwe zimapachikidwa komanso kapangidwe kake kovuta. Tinthu tating'onoting'ono ta ufa wa miyala ndi tovuta kukhazikika mwachilengedwe, ndipo choziziritsira chimakhala ndi mankhwala osiyanasiyana monga ma surfactants, zoletsa dzimbiri, ndi zina zotero, zomwe zimawonjezera kuvutika kwa kuchiza madzi otayira. Ngati sichikukonzedwa bwino, zinthu zolimba zomwe zimapachikidwa m'madzi otayira madzi zimatseka mapaipi, ndipo mankhwala omwe ali mu choziziritsira madzi amaipitsa nthaka ndi madzi.

2, Sefani atolankhani processing otaya

Kampaniyo yayika makina osindikizira opangidwa bwino kwambiri mu makina oyeretsera zinyalala. Choyamba, onjezani polyaluminum chloride ndi polyacrylamide m'zidebe zoyeretsera zomwe zili ndi makina osindikizira zosefera, ndikuzisungunula ndikuzisakaniza muyeso winawake. Mankhwala osungunuka amayendetsedwa bwino ndi pampu yoyeretsera kuti aperekedwe ku thanki yosakaniza ya makina osindikizira zosefera. Mu thanki yosakaniza, mankhwalawo amasakanizidwa bwino ndi madzi a m'nyanja, ndipo ma coagulation ndi flocculation zimachitika mwachangu. Pambuyo pake, madzi osakanikiranawo amalowa m'chipinda chosefera cha makina osindikizira zosefera, ndipo pansi pa kupanikizika, madzi amatuluka kudzera mu nsalu yosefera, pomwe dothi limatsekeredwa m'chipinda chosefera. Pambuyo pa kusefera kwa nthawi yayitali, keke yamatope yokhala ndi chinyezi chochepa imapangidwa, zomwe zimapangitsa kuti pakhale kulekanitsa bwino pakati pa cholimba ndi madzi.

Mwachidule, kugwiritsa ntchito njira yothira mankhwala, kuphatikiza ndi polyaluminum chloride ndi polyacrylamide, komanso kuphatikiza ndi zida zosefera kuti muyeretse madzi otayira pogwiritsa ntchito marble ndi njira yothandiza, yotsika mtengo, komanso yosamalira chilengedwe yokhala ndi phindu labwino.
