Ultrafijn kwartspoeder is een hoogwaardige neutrale anorganische vulstof. Het heeft een sterke zuurbestendigheid, stabiele fysische en chemische eigenschappen, goede lichtdoorlatendheid, hoge di\u00eblektricum, hoge vochtbestendigheid, stralingsbestendigheid, uitstekende weerstand tegen hoge temperaturen en hoge IT-eigenschappen zoals zuiverheid, laag ionengehalte, lage uitzetting en lage spanning. . Het wordt veel gebruikt in kunststoffen, coatings, verven, rubber, keramiek, inkten, katalytische en gasfiltratiematerialen en andere gebieden.<\/p>\n\n\n\n

Onder hen stelt de hightechindustrie zeer strenge eisen aan de zuiverheid, deeltjesgrootte en deeltjesgrootteverdeling van ultrafijn kwartspoeder. Wat de huidige breektechnologie betreft, omvat de ultrafijne breekapparatuur die beschikbaar is voor natuurlijke kwartsmineralen kogelmolens, roermolens, luchtstroommolens, trillingsmolens en verschillende classificatoren.<\/p>\n\n\n\n

Kwartsvoorbehandeling (calcineren + afschrikken met water)<\/h2>\n\n\n\n

De hardheid van kwarts is 7. Als andere mineralen direct worden vermalen, zal het energieverbruik hoog zijn en het rendement laag. Daarom kan eerst thermisch breken worden uitgevoerd, namelijk de calcinatie-water-blusmethode.<\/p>\n\n\n\n

Eerst wordt het kwarts gecalcineerd bij een hoge temperatuur (900~1150\u2103) en vervolgens afgekoeld met water, waardoor het kwarts een snelle \u201cthermische uitzetting\u201d en \u201ckoude contractie\u201d ondergaat, wat resulteert in een groot aantal microscheurtjes op het oppervlak. en binnen het blok, waardoor de sterkte ervan wordt verminderd. , verbeter de verpletterende effici\u00ebntie.<\/p>\n\n\n\n

Wanneer het water aan het blussen is, kunt u het beste geen zwembad gebruiken, omdat er bij het afkoelen veel waterdampbellen op het kwartsoppervlak zullen ontstaan. Vergeleken met vloeibaar water is het niet eenvoudig om warmte te geleiden; het is niet eenvoudig om een \u201csnel afkoelend\u201d effect te cre\u00ebren.<\/p>\n\n\n\n

Bereiding van ultrafijn kwartspoeder door een kogelmolen<\/h2>\n\n\n\n

De kogelmolen + classificator<\/a> complete productielijn is meer geschikt voor ultrafijne verpletterende verwerking van kwarts. Het heeft de kenmerken van een hoge productwitheid, goede vorm en glans, stabiele kwaliteitsindicatoren en een sterke beheersbaarheid van de deeltjesgrootteverdeling.<\/p>\n\n\n\n

Echter, sinds kogelmolens<\/a> en classificatoren hebben verschillende functies en aandachtspunten en worden meestal door twee bedrijven geproduceerd. Er zijn vaak verschillen in concepten zoals output, dus bij het selecteren en ontwerpen van apparatuur moet rekening worden gehouden met het matchen van de twee. Als de toepassing onredelijk is, zal dit functionele beperkingen, een hoog energieverbruik en een lage effici\u00ebntie veroorzaken. Een goede samenwerking kan de respectieve voordelen ten volle benutten, het hele systeem aanvullen, met de helft van de moeite een tweemaal zo hoog resultaat bereiken en zeer effici\u00ebnt zijn.<\/p>\n\n\n\n

Bovendien veroorzaakt de hoge hardheid van kwarts ernstige slijtage aan apparatuur en vervuilt het producten. Op de apparatuur moet een slijtvaste bescherming worden aangebracht, met name siliciumpoeder van hoge zuiverheid van elektronische kwaliteit. Alle statische onderdelen, zoals holtes en buizen, moeten gemaakt zijn van keramische of organische slijtvaste materialen. Materialen etc. voor de voering. Kogelmolens gebruiken over het algemeen aluminiumoxide bekledingsplaten of kogelsteenbekledingsplaten.<\/p>\n\n\n\n

Bereiding van ultrafijn kwartspoeder door trilmolen<\/h2>\n\n\n\n

De vibratie molen<\/a> heeft de voordelen van een laag geluidsniveau, compacte structuur, klein formaat, lichtgewicht, laag energieverbruik, hoge output, geconcentreerde maaldeeltjesgrootte en geen vervuiling. Het geproduceerde ultrafijne siliciumpoeder van elektronische kwaliteit is bolvormig poeder.<\/p>\n\n\n\n

Trillingsmolens<\/a> gebruik over het algemeen aluminiumoxide als voering, en de media zijn meestal aluminiumoxide mediaballen. De trillingsfrequentie heeft rechtstreeks invloed op de maaleffici\u00ebntie van het product, evenals op apparatuurverlies en energieverbruik. Het bepalen van de juiste trillingsfrequentie op basis van de productiecapaciteit en de verwerkingscapaciteit van de classificator is een sleutelfactor voor de effici\u00ebnte en controleerbare productie van producten met een redelijke deeltjesgrootteverdeling. De deeltjesgrootte en de output van het product kunnen worden aangepast door het aantal waaierbladen van de classificator, de waaiersnelheid, de luchtdruk en het luchtvolume van de ge\u00efnduceerde trekventilator en de grootte van het secundaire luchtrooster-afwateringsapparaat aan te passen.<\/p>\n\n\n\n

Luchtstroom-breektechnologie is een van de belangrijkste ultrafijne maaltechnologie\u00ebn. Guo Xiuping kan goede verpletterende effecten bereiken met behulp van een wervelbed jet molen<\/a> kwarts te verpletteren. In de cycloonafscheider en de pulszakstofafscheider kan respectievelijk d95= worden verkregen. Er zijn twee producten: 10\u03bcm en d97=6\u03bcm. De factoren die het materiaalverpletterende effect be\u00efnvloeden, omvatten voornamelijk classificatiestroom, deeltjesgrootte van het voer en classificatiesnelheid.<\/p>\n\n\n\n

Toepassing van maalhulpmiddelen bij het fijnmalen van steenpoeder<\/h2>\n\n\n\n

Tijdens het fijne maalproces van steenpoeder heeft het toevoegen van een passende hoeveelheid maalhulpmiddel niet alleen een maalhulpeffect, maar werkt het ook als dispergeermiddel. Veel voorkomende maalhulpmiddelen zijn polyacrylamide, natriumchloride, silicaat, triethanolamine, natriumdodecylsulfonaat, enz.
De hoeveelheid maalhulpmiddel moet geschikt zijn. Over het algemeen neemt het maaleffect toe naarmate de dosering toeneemt. Na het bereiken van de optimale waarde zal het verhogen van de dosering het maaleffect verergeren.<\/p>","protected":false},"excerpt":{"rendered":"
