Ceev faj Thaum Siv
1. Khaws ib qho dej
Ion txauv resin muaj qee qhov dej thiab yuav tsum tsis txhob muab tso rau hauv qhov cua qhib. Thaum lub sijhawm khaws khoom thiab thauj mus los, nws yuav tsum tau khaws kom ntub dej kom tsis txhob muaj huab cua qhuav thiab lub cev qhuav dej, ua rau cov pob zeb tawg. Yog tias cov kua dej tau qhuav thaum khaws cia, nws yuav tsum tau tsau rau hauv cov dej qab ntsev (25%), thiab tom qab ntawd maj mam maj mam. Nws yuav tsum tsis txhob muab ncaj qha rau hauv dej, yog li txhawm rau zam kev nthuav dav sai thiab tawg pob zeb.
2. Khaws qhov kub thiab txias
Thaum khaws cia thiab thauj mus los thaum lub caij ntuj no, qhov kub yuav tsum tau khaws cia ntawm 5-40 ℃ kom tsis txhob muaj cua txias lossis kub dhau, uas yuav cuam tshuam rau qhov zoo. Yog tias tsis muaj cov cuab yeej tiv thaiv cua sov nyob rau lub caij ntuj no, cov yas tuaj yeem khaws cia hauv cov dej ntsev, thiab cov dej qab ntsev tuaj yeem txiav txim siab raws li qhov ntsuas kub.
3. 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.
4. Kev kho kom nquag plias
Hauv kev siv, cov tshuaj tuaj yeem tiv thaiv kom tsis txhob maj nrawm nrog cov hlau (xws li hlau, tooj liab, thiab lwm yam) cov roj thiab cov khoom siv organic. Cov anion cob yog ib qho yooj yim kom muaj kuab paug los ntawm cov teeb meem organic. Nws tuaj yeem ntub lossis yaug nrog 10% NaC1 + 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 txoj hauv kev kuj tseem tuaj yeem siv, xws li kua qaub alkali hloov kho, kho tshuaj dawb, kho cawv thiab ntau txoj hauv kev kom tsis muaj menyuam.
