Pii dioxide est un chargeur inorganique fonctionnel de haute pureté et ultra-fin, largement utilisé dans l’industrie moderne de fabrication du papier. Doté d’une granulométrie uniforme, d’une excellente performance de diffusion lumineuse, d’une blancheur élevée et d’une inertie chimique stable, il constitue un matériau auxiliaire idéal pour le revêtement de surface du papier, le remplissage des pâtes à papier et la modification de papiers spéciaux. Contrairement aux chargeurs traditionnels utilisés dans la fabrication du papier, la silice (SiO₂) améliore efficacement la douceur, l’absorption de l’encre, la résistance à l’usure et la texture globale du papier, sans nuire à sa sécurité. Elle est couramment employée dans la production de papier d’impression, de papier couché, de papiers industriels spécialisés et de papiers d’emballage courants. Cet article explique, en termes simples et clairs, ses fonctions essentielles et ses valeurs pratiques dans la fabrication du papier.
Functionis simplicissima dioxide silicii est melioratio voluminis, levitatis et planitiei papiri. In processibus antiquis fabricandi papyrum, fibræ puræ pulpæ formant superficies microscopicas inaequales, cum fossulis et interstitiis minutissimis, post formationem laminarum et siccationem. Haec defectus subtilia faciunt superficiem papyri asperam, pronam ad barbas et inaequalitatem crassitudinis, quae effectus impressionis et scripturae magnopere impediunt. Dioxide silicii constat ex particulis sphaericis ultrafinis, quae interstitia inter fibras pulpae plene implent. Ita superficies papyri inaequales aequantur, levitas et planities superficiei notabiliter meliorantur. Papyrus finitus sentitur delicatus et planus, sine textura aspera, optima praebens conditio superficiei pro impressione altae praecisionis et processibus struendi.
Dioxidum silicii augmentat albedinem, opacitatem et texturam visualem papyri. Papyrus praecellens pro impressione et papyrus pro confectione necessitant albedinem altam et opacitatem bonam ut evitentur transmissio lucis et penetratio figurarum. Dioxidum silicii habet facultatem excellentem diffundendi lucem et tonum album purum altum. Cum adicitur ad pulpam aut ad materias pro strato superficiali, efficaciter meliorat albedinem et opacitatem totius papyri. Impedit transmissionem lucis in papyro tenui, certificat figuras impressas claras sine penetratione fundi, et facit colorem papyri uniformem, lucidum et stabilem, vitans flavescere et tonum obscurum qui in papyro ordinarie communis est.
It greatly optimizes ink absorption and printing adaptability, solving printing blurring problems. Ordinary paper has poor ink fixation capacity. During high-speed printing, ink is difficult to dry quickly, easily causing ink diffusion, pattern blurring, overlapping smudges and incomplete color development. Silicon dioxide forms a dense and uniform micro-pore structure on the paper surface. These tiny pores can evenly absorb and lock printing ink, accelerate ink drying speed, and fix color pigments firmly on the paper surface. It effectively improves printing definition, makes text and patterns clear and layered, and adapts to high-speed industrial printing production needs.
Dioxidum silicii resistentiam ad attritionem superficiei papiri et fortitudinem tractionis augent. Papirus ex puris fibris densitatem superficialem infimam habet et stabilitatem structuralem debilem. Facile pulvis papiraceus, attritio superficiei et rimae in marginibus durante impressione, sectione et usu cotidiano generantur. Effectus densus implendi dioxidum silicii structuram internam fibrarum papiri comprimit, duritiem superficialem et resistentiam ad frictionem augent, et cadum pulvis papiracei minuit. Interim, cohaesionem inter fibras meliorat, fortitudinem tractionis et lacerationis papiri roborat, interruptionem papiri durante processu prohibet, et procentum productorum papiraceorum perfectorum augent.
It achieves excellent anti-yellowing and aging resistance for long-term paper preservation. Paper products are easily affected by air oxidation, light irradiation, and temperature and humidity changes during storage and use, resulting in gradual yellowing, brittleness, and reduced toughness. Silicon dioxide has stable chemical properties and outstanding anti-oxidation and light resistance. It can isolate external environmental erosion, slow down the aging speed of paper fibers, maintain long-term stable whiteness and toughness, and avoid yellowing, brittle cracking, and quality degradation. This function is especially suitable for high-grade packaging paper, archival paper, and long-term preserved printing paper.
Dioxidum silicii optimat effectum strati in productione chartae obductae. Charta obducta dependet a stratis obductis superficialibus ad obtinendum altam luciditatem et subtilia effectus impressionis. Formulae obductae tradicionales sunt pronae ad obductionem inaequalem, planitatem infelicem et facilem exfoliationem. Dioxidum silicii additum in sulpam obductam chartae potest meliorare fluiditatem obductionis et effectum planitatis, facere stratum obductum uniformem et tenue, et augere vim adhaesionis inter stratum obductum et basim chartae. Superficies obducta post coagulationem est lisa, lucida et non facile exfoliabilis aut decidens, notabiliter meliorans gradum et effectum impressionis chartae obductae alti gradus.
It adapts to the production of various special functional paper products. With safe and stable physical and chemical properties, silicon dioxide can be used for the modification of special paper such as oil-proof paper, moisture-proof paper, and filter paper. It can form a dense protective structure inside the paper layer, improve the paper’s oil resistance and water permeability resistance, and enhance the stability of functional paper. In addition, it has good air permeability, which will not block the fine pore structure of filter paper, ensuring that special paper maintains stable functional performance while improving texture strength.
Dioxidum silicii habet bonam praestantiam in protectione ambientis et altam praestantiam in pretio productionis. Est materiale inorganicum non toxicum, inodorum et sine pollutione, sine componentibus nocivis quae effluuntur dum pulpatur, cooperitur, aut productum finitum utitur. Plene satisfacit normis securitatis pro chartis cotidianis, chartis pro emballagio ciborum, et chartis pro impressionibus. Praeterea, dioxidum silicii habet altam efficaciam implendi. Parva dosis potest notabiliter meliorare qualitatem chartae, substituere partem pretiosae materiae primae pulpa lignea, efficaciter minuere pretium productionis chartarum, et meliorare utilitates oeconomicas fabricatorum chartarum.
In summa, dioxide silicii est additivum functionale vitale pro industria hodierna fabbricandae chartae. Meliorat levitatem, albedinem et opacitatem chartae, augent absorptionem atramenti et perspicuitatem impressionis, fortificant robur et resistentiam ad attritionem chartae, et retardant aetationem et flavescendum chartae. Cum praestet securitatem, latam adaptabilitatem et altam efficaciam pretii, iam factum est materia prima essentialis ad meliorandum chartam ordinarium et ad producendum chartam specialem gradus alti.
