Dej kho mob yog cov tshuaj chemicals, dej hauv tsev, dej khib nyiab thiab lwm yam tshuaj tsim nyog rau hauv tus txheej txheem, los ntawm kev siv cov tshuaj no, dej tuaj yeem ncav cuag qhov tsis muaj kev txwv zoo. Nws cov nyhuv thawj yog tswj kev tsim cov nplai thiab dej, ua kom cov npuas dej tsawg, txo qhov kev sib txuas nrog dej yaig ntawm cov ntaub ntawv, tshem tawm cov khib nyiab thiab cov tshuaj lom nyob hauv dej, deodorant tshuaj dawb, ua kom dej zoo.
1, txhuam qhov hauv siab:
Inorganic ntsev yog ib qho tseem ceeb heev rau ib chav kawm ntawm kev txhuam kev lim dej. Cov chromium, phosphorus, zinc, silicon, molybdenum, tungsten thiab tag nrho cov organic formulations uas siv rau hauv daim ntawv no yog hais txog kev siv cov chromates, phosphates, zinc sulphates, silicates, molybdates, Tungstates thiab organic phosphonates.
Tag nrho cov organic formulations tsis siv cov khoom qab ntsev, tshwj xeeb tshaj yog hnyav hlau inorganic salts, los txo cov pa phem ntawm qhov chaw. Organic phosphonates feem ntau siv los ua cov tshuaj txhuam kev txhuam hauv cov organic formulations. Aromatic azole yog siv rau tooj liab thiab nws cov hlau txhuam hauv corrosion inhibitor, feem ntau siv hauv domestic benzotriazole thiab mercaptobenzotriazole.
2, organic flocculant:
Organic flocculant yog muab faib ua plaub pawg: hluavtaws polymer flocculant, natural polymer hloov flocculant, microbial flocculant thiab ntau tus neeg ua haujlwm kho dej. Synthetic polymer flocculants mas polyacrylamide (PAM) thiab nws cov derivatives. Kev hloov cov nplaim hluav taws xob muaj xws li hmoov nplej, cellulose, yas ntoo, polysaccharides, thiab protein ntau thiab lwm yam kev derivatives, tam sim no cov nyiaj tau los txog 20% ntawm cov pob zeb tawg paj, microbial flocculant hais txog kev siv qee qhov Microbial secretion ntawm macromolecules rau flocculants. Suav Academy ntawm Sciences Lub koom haum ntawm Microbiology thiab lwm qhov chaw muaj kev tshawb nrhiav zoo.
