Kuisa Chigadzirwa Panzvimbo

Cationic Polyacrylamide (CPAM muchidimbu) ipolymer inonyungudika mumvura ine cheni yemolecular chain ine chain yakanaka (-NH₃⁺). Kuburikidza ne "charge adsorption + net capture" inosangana nezvinhu zvakasimba zvakanyungudika zvisina chaji (zvakadai sevhu necolloid), zvinhu zvakanyungudutswa zve organic (zvakadai se humic acid), uye zvinosvibisa zvine chaji zvisina chaji (zvakadai se dye anions) mumvura, inokurumidza kuunganidza nekubvisa zvidimbu zvidiki, zvichiita kuti ive "chishandiso chine simba chekubvisa ruvara netsvina" mumamiriro ezvinhu ane turbidity shoma uye kusvibiswa kwakanyanya, zvakaita sekudhinda nekupenda, electroplating, uye chemical engineering.

Zvinhu Zvikuru

• Ionicity Inogadziriswa · Kugadziriswa Kwakarurama: Ionicity (cationic charge density) inotangira pa10% kusvika 80% (inogadziriswa), inogona kugadziriswa zvichienderana nekusimba kwechaja yemvura yakasviba:

￮ Ionicity yakaderera (10%-30%): Yakakodzera mvura yakasviba isina kunyorova zvakanyanya, isina chaji yakakwana (yakadai semvura yepamusoro isati yagadziriswa);

Dhigirii repamusoro reionic (50%-80%): Yakakodzera mvura yakasviba ine chaji yakanyanya uye zvinhu zvakasimba zvakasungirirwa zvakanaka (zvakadai sekudhinda nekudhaya mvura yakasviba, mvura yakasviba inoputirwa nemagetsi).

• Kunyungudika nekukurumidza, zvisaririra zvishoma: Nguva yekunyungudika kweupfu hwePAM ≤ maminetsi makumi matanhatu (patembiricha yemumba), mushure mekunyungudika, maflocs akakura uye anogadzikana nekukurumidza (kumhanya kwekugadzikana kunokurumidza 25%-40% kupfuura zvigadzirwa zvemazuva ese), uye inoshanda zviri nani kana ikashandiswa pamwe chete nePAC. Zvinhu zvisinganyungudike mumvura ≤ 0.5%.

• Kushivirira Kwakasimba: Inodzivirira acid nealkali (pH 3-12), haipindi tembiricha (-5°C kusvika 90°C), yakakodzera munzvimbo dzakasiyana siyana dzakadai semvura yakasviba yemugodhi, kugadzira mapepa edoro dema, kudhinda nekudhaya mvura yakasviba, uye mvura yekuisa mafuta muminda.

Nzvimbo Yekushandisa

• Kucheneswa kwetsvina yemuguta: Kurumidza kubvisa mvura mumarara uye kuvandudza kushanda zvakanaka kwekuchenesa.
• Kurapa mvura yakasviba mumaindasitiri: Kugadziriswa kwemvura yakasviba ine huwandu hwakawanda kubva kumigayo yesimbi, mafekitori emagetsi, migayo yemapepa, nezvimwewo.
• Kushandiswa kwemafuta muminda yemafuta: Vandudza kudzoreredza mafuta uye gadzirisa kusimba kwekuisa mafuta mumvura.
• Bepa neMachira: Wedzera simba repepa uye kuderedza kurasikirwa nefaibha.
• Kuvandudzwa kwevhu: kudzivirira kukurwa kwevhu uye kuwedzera kuchengetedza mvura muvhu.

Kurongedza uye Kuchengeta

• Upfu hwakaoma: Bhegi rakarukwa re25kg rakafukidzwa nebhegi repurasitiki / bhegi guru retani imwe (pakeji yelogo yeChirungu / yemutengi inogadziriswa inowanikwa);
• Mamiriro Ekuchengetedza: Chengeta munzvimbo inotonhorera, yakaoma (tembiricha ≤ 35°C), usavheneke zuva zvakananga; nguva yekushanda kwechigadzirwa ichi makore maviri (chisina kuvhurwa).
