Frictional silica 1. Product Overview (Product Overview) 1.1 Basic definitions Zhongqi Frictional Silica, isithako esisebenzayo esikhiqizwa ngokuqhubekayo, sitholakala njengepowder emhlophe. Isici sayo esiyinhloko siwukwakheka okungajwayelekile okunezikhala ezijulile ezinezingxenye ezijikelezayo, kuhlanganisa ukusebenza kahle kokuguga nokukwazi ukuhamba kwezithako ezisebenzayo. Le msebenzi engaphenduli ivimbela ukuxhumana nefluoride nezinto zokukhanyisa ezikhiqizweni zamathambo, isebenza njengomsebenzi ophakathi kokuguga okuphumelelayo nokuvikela i-enamel. 1.2 Core values Njengomgomo obalulekile wokusebenza kahle kokuhlanza amathambo, Zhongqi Frictional Silica ibhekana kahle nezinkinga zemboni ezifana nokugqokwa kwe-enamel nokuhlanza okungalingani okubangelwa izithako ezijwayelekile. Ngokulawula kahle izinga lokuguga nezakhiwo zezinhlayiya, iklanyelwe izimo ezahlukene zokunakekelwa kwamazinyo okuhlanganisa abantwana, abadala, kanye nokunakekelwa kwamazinyo abuthakathaka. Ukwakhiwa okunezikhala kuqhubekisela phambili isikhathi sokugcina kwezithako ezisebenzayo emlonyeni, kuhlinzeka ngezixazululo zokuhlanza eziphephile nezisebenzayo zamathambo aphakathi nendawo kuya phezulu. 2. Product Characteristics (Product Characteristics) 2.1 Structural and performance advantages •Precise wear control: Indlela yokuhlunga isetshenziswa ukuze kwakhiwe isakhiwo sezinhlayiya "esinamathambo aqinile + umphetho opholile", futhi inani le-RDA lingashintshwa njengoba kudingeka (uhlobo lwabantwana ≤50, uhlanga lwabantu abadala 70-120, uhlanga lokukhanyisa 120-150), okuhlanza futhi kwehlisa ukugqokwa kwe-enamel. •High efficiency adsorption capacity: isakhiwo esinezinhlayiya singenza ukuthi sithathe ama-polyphenols etiye, i-chlorhexidine nezinye izithako ezisebenzayo, futhi amandla okuthatha aphezulu kakhulu kunezithako ezijwayelekile. •Excellent compatibility performance: inani le-pH 6.0-7.0, ukuhambisana okuhle nefluoride, akuphazamisi ukusebenza kwezithako ezivimbela izimbungulu; ubukhali buphakeme kune-96%, abuphazamisi ukujwayeleka kombala wepasta ngemuva kokuhlanganiswa ne-matrix ye-toothpaste. 3.

Application fields (Application Fields) 4.1 Oral care for children •Suitable for children aged 0-12 years old. Low abrasion model with RDA value ≤50 can reduce the wear of milk teeth and achieve mild cavity prevention together with fluoride. 4.2 Adult basic cleaning •For daily care toothpaste, the 70-100μm particle size model can effectively remove food residues and plaque, improve the cleaning efficiency of brushing, and is suitable for basic formulations such as fluoride and antibacterial. 4.3 Whitening toothpaste •The medium and high wear model of 8-12μm removes tea stains and smoke stains through physical friction, and combines with mesoporous structure to adsorb whitening agent, realizing the "friction-adsorption" double whitening. 5. Standards and regulations (Standards & Regulations) •Comply with national and industry standards: GB/25576-2020 index requirements. •Obtain relevant qualification certification: food additive production license, CMA/CNAS testing certification. •Follow the safety specifications: heavy metal and microbial indicators are fully up to standard, and total bacterial count is less than or equal to 1000CFU/g. 6. Product Advantages (PA) •Precise classification and adaptation: the models are subdivided according to the population and efficacy, and the RDA value gradient is controllable to meet the cleaning needs of all scenarios. •Excellent safety performance: smooth particle morphology reduces enamel wear, and is suitable for sensitive people after oral mucosal irritation test. •Strong synergistic efficacy: porous structure enhances the utilization rate of active ingredients, and synergizes cleaning and efficacy components. •Batch stability and reliability: the airflow classification technology guarantees the uniform particle size, the performance deviation between batches is less than or equal to 5%, suitable for large-scale production. 7. Factory advantages Zhongqi Guangdong Silicon Materials Co., Ltd., ibhizinisi eliphakeme lezobuchwepheshe kanye nebhizinisi elikhethekile, elihlelekile, eliyingqayizivele, nelisha, selivele selisebenza embonini iminyaka engaphezu kwengu-20. Le nkampani inezobuchwepheshe eziyi-17 ezivunyiwe futhi isebenza isizinda sokukhiqiza esiqinisekiswe yi-GMP. Ihlome ngezinsiza zokuhlola ezithuthukile ezihlanganisa ama-spectrometers e-atomic fluorescence kanye ne-laser particle analyzers, isungule uhlelo oluphelele lokulawula ikhwalithi oluhlanganisa izinqubo zokuhlola eziyi-26 kusukela ezinsizeni zokwakha kuya emikhiqizweni eqediwe.
