Producteigenschappen:

De kleur melkachtig wit of lichtgeel maakt het verwerkingsproces gemakkelijker en de scheiding en zuivering van de gekleurde organische verbindingen zijn gemakkelijk te observeren.
De fysieke en chemische eigenschappen zijn stabiel en het is onoplosbaar in zuren, basen en organische oplosmiddelen, wat handig is voor de selectie van adsorbens en desorbens.
Het heeft een goede selectiviteit voor organisch materiaal en wordt niet beïnvloed door de aanwezigheid van anorganische zouten.
De regeneratie is eenvoudig. Het regeneratiemiddel kan worden gekozen uit water, verdunde alkali, verdund zuur of laagkokende organische oplosmiddelen, zoals methanol, ethanol, aceton, enz.
Goede mechanische sterkte en lange normale levensduur.

Harsvoorbehandeling

Harsen van industriële kwaliteit bevatten allemaal inerte oplosmiddelen, dus ze moeten in verschillende mate worden voorbehandeld, afhankelijk van de toepassing: voeg in de extractor 10-20 cm ethanol toe boven de harslaag en laat 3-4 uur weken. Tap vervolgens de weekoplossing af. Gebruik dezelfde methode om herhaaldelijk te wassen totdat de uitlaat de weekoplossing vult en voeg drie keer zoveel water toe aan de reageerbuis totdat deze niet meer troebel is. Spoel de reageerbuis vervolgens grondig met schoon water totdat er geen ethanol meer te ruiken is. Daarna is de reageerbuis klaar voor algemeen gebruik.

Verbeterde regeneratie:

Wanneer de hars gedurende een bepaalde periode normaal wordt gebruikt, de adsorptiecapaciteit afneemt of de hars ernstig vervuild is, is het noodzakelijk om de regeneratiebehandeling te intensiveren. De methode bestaat uit het toevoegen van een 3-5% zoutzuuroplossing 10-20 cm boven de harslaag en deze 2-4 uur te laten weken. Dezelfde concentratie, 5-7 keer het volume zoutzuuroplossing, werd gespoeld en vervolgens grondig gespoeld met schoon water tot de pH-waarde van de uitlaatwasoplossing neutraal was. Vervolgens werd de oplossing 2-4 uur geweekt in een 5% natriumhydroxide-oplossing volgens de bovenstaande methode en werd dezelfde methode toegepast. Spoel tot er 5-7 keer het volume natriumhydroxide-oplossing is gepasseerd en spoel vervolgens grondig met water tot de pH van het effluent neutraal is. Daarna kan het opnieuw in gebruik worden genomen.

Voorzorgsmaatregelen

De hars bevat water en moet tijdens opslag en transport op een temperatuur van 5-40ºC worden gehouden om bevriezing bij lage temperaturen en schimmelvorming bij hoge temperaturen te voorkomen, wat de werking zou kunnen beïnvloeden.
Omdat de hars aan de lucht wordt blootgesteld of om welke reden dan ook water verliest, mag u geen water rechtstreeks injecteren om te voorkomen dat de hars gaat drijven. U kunt de hars met ethanol impregneren om hem weer vochtig te maken en vervolgens met water reinigen.
De geadsorbeerde stof (oplossing) moet worden onderworpen aan verwijdering van onzuiverheden, filtratie en klaring voordat deze op de kolom wordt geplaatst, om zoveel mogelijk te voorkomen dat er onzuiverheden in de harskolom terechtkomen en om acute harsvergiftiging te voorkomen en het gebruik ervan te beïnvloeden.
De hars is onderbroken. Na het wassen met water moet het worden bewaard in geweekt schoon water en regelmatig worden ververst om besmetting te voorkomen. Het kan ook worden ondergedompeld in verzadigde zoutoplossing of ethanol voor langdurige opslag.
