Ua ntej, cov laj thawj tseem ceeb rau kev txo qis ntawm lub zog ntawm ion txauv resin yog:
1. Cov ion txauv resin yog decomposed vim qhov kev ua ntawm cov oxidants muaj zog, uas txo lub zog ntawm resin. Qhov xwm txheej no feem ntau tshwm sim nyob rau hauv qhov zoo resin, piv txwv li, vim yog kev tswj cov tshuaj chlorine seem hauv dej. Tab sis qhov tsis zoo resin los ntawm cov pa phem loj ntawm cov khoom organic tseem yuav degrade thiab cuam tshuam rau nws lub zog. Los ntawm cov kev paub dhau los ntawm kev ua haujlwm, nws yog ib qho tsim nyog yuav tsum tau txo qis kev siv cov pa oxygen kom qis dua 1mg / L (27 degree, potassium manganate oxidation rau 4h), thiab qee cov kev cai txawv teb chaws ntawm kev siv cov pa oxygen.<0.3mg/L.
2. Cov ion txauv resin puas lawm vim kev sib txhuam txhua zaus, xws li rov qab siv dua, kev thauj khoom ceev ceev, kev sib pauv ntau dhau, huab cua thiab ultrasonic txhuam, thiab lwm yam, uas cuam tshuam rau lub zog ntawm cov resin.
3. Vim tias cov ion txauv resin qee zaum ua haujlwm nyob rau hauv lub siab thiab ntws tus nqi, qhov sib txawv ntawm cov dej nkag thiab qhov hluav taws xob siab yog loj heev, thiab cov resin yog crushed thiab poob nws lub zog.
4. Vim hais tias lub ntim expansion ntawm cov resin yog loj heev nyob rau hauv lub lag luam, piv txwv li, expansion tus nqi ntawm cov resin thaum lub sij hawm transformation yog ceev heev thiab loj heev, thiab lub zog ntawm resin yog txo los ntawm kev rov nthuav dav thiab contraction.
5. Lub thermal stability ntawm cov resin tsis zoo, thiab cov dej kub yog siab dhau thaum siv, xws li cov condensate rov qab dej kub yog qhov siab, uas feem ntau ua rau cov resin tawg thiab txo lub zog.
6. Vim yog qhov chaw cia khoom tsis raug, dej qhuav, thaum nws ntsib dej, nws yuav tawg; Los yog qhov kub ntawm qhov nruab nrab qis dua 0 degree C, vim yog cov dej khov hauv cov resin thiab o, crushing, ua rau txo lub zog ntawm cov resin.
Qhov thib ob, yuav ua li cas cais anion thiab cation txauv resin tom qab sib tov?
Hauv kev ua haujlwm, cov resins feem ntau sib xyaw thiab yuav tsum tau sib cais. Txoj kev sib cais:
Cov khoom sib xyaw ua ke hauv cov kua ntsev saturated, tom qab qee lub sij hawm ntawm kev nplawm, siv cov txheeb ze ntawm Yin thiab Yang resin nyob rau hauv cov kua ntsev saturated, lub floating thiab sinking kev ua tau zoo sib txawv. Lub zog acid anion txauv resin yuav ntab rau hauv txheej sab saud, thiab lub zog acid cation txauv resin yuav tog hauv qab txheej, uas nws yuav raug muab cais tawm.
Iii. Nws txhais li cas tias cov ion pauv resin ua tsaus tom qab siv?
Ib qho ion pauv resin yog cov khoom siv pob tshab lossis pob tshab uas txawv ntawm cov xim nyob ntawm nws cov muaj pes tsawg leeg. Tag nrho cov styrene resins yog daj. Acrylic resins tsis muaj xim thiab pob tshab, thiab qee qhov yog mis nyuj dawb. Feem ntau hais lus, tus neeg sawv cev crosslinking ntau dua, cov impurities nyob rau hauv cov khoom siv raw yog ntau dua, thiab cov xim ntawm cov resin tsim yog tob.
Tom qab cov ion txauv resin siv rau lub sijhawm, nws cov xim yuav tsaus dua vim muaj kuab paug ntawm cov hlau los yog cov organic hauv dej. Cov xim ntawm qhov ua tsis tiav ion txauv resin yog me ntsis tsaus dua li ntawm cov regenerated resin.
