Kev tshem tawm tsis huv
Cov khoom lag luam ntawm cov khoom sib pauv ion feem ntau muaj cov khoom me me ntawm cov polymer qis thiab tsis muaj monomer uas tsis muaj kev cuam tshuam, nrog rau cov khoom tsis huv xws li hlau, txhuas thiab tooj liab. Thaum cov tshuaj sib txuas nrog dej, kua qaub, alkali lossis lwm yam kev daws teeb meem, cov tshuaj saum toj no yuav raug xa mus rau hauv kev daws teeb meem, cuam tshuam qhov zoo ntawm cov dej ntws tawm. Yog li ntawd, cov tshuaj tshiab yuav tsum tau kho ua ntej siv. Feem ntau, cov dej tau siv los ua cov tshuaj txhuam kom nthuav dav, thiab tom qab ntawd, Cov khoom tsis huv (feem ntau yog cov hlau sib txuas) tuaj yeem tshem tawm los ntawm 4-5% dilute hydrochloric acid, thiab cov organic tsis huv tuaj yeem tshem tawm los ntawm 2-4% dilute sodium hydroxide kev daws teeb meem Yog tias nws tau siv hauv kev npaj tshuaj, nws yuav tsum tau so hauv ethanol.
Kev Kho Kom Zoo Sijhawm
Hauv kev siv cov khoom siv, nws yog qhov tsim nyog los tiv thaiv kev sib cuag nrog cov pa phem, cov organic molecular microorganism, muaj zog oxidant thiab lwm yam hlau (xws li hlau, tooj liab, thiab lwm yam) txhawm rau zam kev txo qis peev txheej sib pauv lossis txawm tias poob haujlwm Yog li, cov tshuaj yuav tsum tau ua haujlwm tsis xwm yeem raws li qhov xwm txheej. Txoj hauv kev ua kom muaj peev xwm tuaj yeem txiav txim siab raws li cov pa phem thiab xwm txheej. Feem ntau, cov cation cob tau yooj yim kom muaj kuab paug los ntawm Fe hauv kev ua kom mos los ntawm hydrochloric acid immersion, Tom qab ntawd maj mam maj mam, cov tshuaj anion yooj yim kom muaj kuab paug los ntawm cov organic. Nws tuaj yeem tsau lossis ntxuav nrog 10% NaCl + 2-5% NaOH sib tov tov. Yog tias tsim nyog, nws tuaj yeem tsau rau hauv 1% hydrogen peroxide tov rau ob peb feeb. Lwm yam, tseem tuaj yeem siv cov kua qaub-puag hloov kho, kho tshuaj dawb, kho dej cawv thiab ntau txoj hauv kev kom tsis muaj menyuam.
Kev kho dua tshiab Resin
Kev kho dua tshiab ntawm cov tshuaj tshiab: hauv cov khoom lag luam ntawm ion txauv resin, muaj me me ntawm oligomers thiab monomers uas tsis koom nrog hauv cov tshuaj tiv thaiv, thiab tseem muaj cov khoom tsis huv xws li hlau, txhuas thiab tooj liab. Thaum cov tshuaj hu rau dej, kua qaub, alkali lossis lwm yam tshuaj, cov tshuaj saum toj no yuav raug xa mus rau hauv cov tshuaj, uas yuav cuam tshuam rau qhov zoo ntawm cov dej ntws. Yog li ntawd, cov tshuaj tshiab yuav tsum tau kho ua ntej siv. Feem ntau, cov tshuaj yuav nthuav nrog dej, thiab tom qab ntawd cov tshuaj tsis huv (feem ntau yog cov hlau sib txuas) tuaj yeem tshem tawm los ntawm 4-5% dilute hydrochloric acid, thiab cov organic tsis huv tuaj yeem tshem tawm los ntawm 2-4% dilute sodium hydroxide tov kom ntxuav ze ze nruab nrab
