Isici sayo esiyinhloko siwukwakheka okungajwayelekile okunezikhala ezijulile ezinezinhlangothi ezijikelezayo, kuhlanganisa ukusebenza kahle kokuguguleka nokukwazi ukuheha izithako ezisebenzayo. Le msebenzi engaphenduli ivimbela ukuxhumana nefluoride nezinto zokukhanyisa ezikhiqizweni zokuhlanza amazinyo, isebenza njengomkhiqizo ophakathi kokuguguleka ofinyelela ibhalansi phakathi kokuhlanza kahle nokuvikela i-enamel. 1.2 Core values Njengomgomo obalulekile wokusebenza kahle kokuhlanza amazinyo, Zhongqi Frictional Silica ixazulula kahle izinkinga zomkhakha ezifana nokugqwala kwe-enamel nokuhlanza okungalingani okubangelwa yizinto zokuguguleka zendabuko. Ngokuqondile ukulawula amanani okuguguleka nokwakheka kwezinhlayiya, iklanyelwe izimo ezahlukene zokunakekelwa kwamazinyo kubandakanya abantwana, abantu abadala, kanye nokunakekelwa kwamazinyo abuthakathaka. Ukwakheka okunezikhala kwandisa isikhathi sokugcina izithako ezisebenzayo emlonyeni, kuhlinzeka ngezixazululo zokuhlanza eziphephile nezisebenzayo zokuhlanza amazinyo aphezulu. 2. Product Characteristics (Product Characteristics) 2.1 Structural and performance advantages •Precise wear control: Indlela yokuhlunga isetshenziswa ukwakha isakhiwo sezinhlayiya "esigcwele ngaphakathi + umphetho opholile", futhi inani le-RDA lingashintshwa njengoba kudingeka (uhlobo lwabantwana ≤50, uhlanga lwabantu abadala 70-120, uhlanga lokukhanyisa 120-150), okuhlanza futhi kwehlisa ukugqwala kwe-enamel. •High efficiency adsorption capacity: isakhiwo esinezinhlayiya singakwazi ukuheha ama-polyphenols etiye, i-chlorhexidine nezinye izithako ezisebenzayo, futhi amandla okukhanga aphezulu kakhulu kunezinto zokuguguleka ezijwayelekile. •Excellent compatibility performance: inani le-pH 6.0-7.0, ukuhambisana okuhle nefluoride, akuphazamisi ukusebenza kwezingxenye ezivimbela izimbungulu; ubukhazikhazi 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 eliphezulu lezakhiwo zikazwelonke kanye nebhizinisi elikhethekile, elihloniphekile, eliyingqayizivele, nelisha, selivele emkhakheni iminyaka engaphezu kwemibili. Le nkampani iphethe ubuchwepheshe obuphathelene nezimvume eziyi-17 futhi isebenza ngesisekelo sokukhiqiza esiqinisekisiwe se-GMP.
