I-Colloidal Antimony Pentoxide Flame Retardant Esebenza Kakhulu: UMCAP38 kanye ne-UMCAP46 – Okuthandwayo Ukushintshwa
Ngokuphikisana nokuthuthukiswa kwe-flame retardant yomhlaba wonke kanye nezindinganiso eziqinile zemvelo, i-colloidal antimony pentoxide (CAP) isibe yisisekelo sokubambisana kwe-flame retardant yezindwangu, izindwangu, ama-resin kanye nemicu yokwenziwa, ngenxa yokusebenza kwayo kahle, umthelela ophansi kanye nobungane bemvelo.
I-UrbanMines Tech, uchwepheshe we-R&D kanye nokukhiqiza izinto ezisezingeni eliphezulu ezisekelwe ku-antimony, wethula i-UMCAP38 (38% i-colloidal Sb₂O₅) kanye ne-UMCAP46 (46% i-colloidal Sb₂O₅). Lawa mabanga okulinganisa afana ncamashi futhi athatha indawo ye-NYACOL A1540 / A1550 ngokugcwele, eletha izixazululo ezingabizi kakhulu nezithembekile zokuvimbela umlilo emhlabeni jikelele.
Izakhiwo Zomkhiqizo Eziyisisekelo: I-Nano-Colloidal, Ikhwalithi Ehambisanayo
Zombili izinhlobo ziyi-anionic dispersions ezisekelwe emanzini ezinokubukeka okufana nobisi nomhlophe. Ingxenye esebenzayo yi-nano-scale antimony pentoxide (Sb₂O₅), ekhiqizwa ngenqubo ethuthukisiwe ye-reflux oxidation. Zimelana nokusatshalaliswa futhi zigcina ukuzinza okuhle kokusatshalaliswa ngaphansi kwezimo ezijwayelekile. Zilungiselelwe nge-triethanolamine, zithuthukisa ukucutshungulwa futhi zifanelane nazo zonke izinhlelo zamanzi kanye nezicelo zezimboni.
UMCAP38: Okuqukethwe kwe-Sb₂O₅ ≥38%. Kufana ne-NYACOL A1540. Kusebenza ngezindlela eziningi ezindwangu, ezimbozweni kanye nasezinhlayiyeni.
UMCAP46: Okuqukethwe kwe-Sb₂O₅ ≥46%. Ukwakheka kwezinhlayiya ezincane ezilawulwayo. Kwenzelwe imicu ye-modacrylic, okuthatha indawo ye-NYACOL A1550. Kukhiqizwa ngobuningi ngabakhiqizi be-modacrylic fiber abaphambili eNingizimu-mpumalanga ye-Asia naseMpumalanga Ephakathi.
Izinzuzo Eziyinhloko: Ukusebenza Okuphezulu Kwezidingo Zezimboni
Izinzuzo Eziyinhloko Ezihlanganyelwe (UMCAP38 kanye ne-UMCAP46)
1. Ukungena kwe-nano, akukho ukulahleka kwempahla Izinhlayiya ezinobukhulu be-nano zinikeza ukungena okuhle kakhulu kwe-substrate, zihlangana ngokujulile nezingubo, amafilimu, imicu kanye nama-resin. Zikhulisa ukubambezeleka komlilo ngaphandle kokuphazamisa amandla omshini, ukucaca noma ukubukeka — zilungele ukusetshenziswa okusobala kancane.
2. Umbala ophansi, ugcina umthunzi wokuqala. Ukusabalala koketshezi okuhle kakhulu kugwema ukushintsha kombala. Kuqeda ukuphuzi/ukuba mnyama okuvamile kubantu abagcina umbala ngendlela yendabuko, kuhlangabezana nezidingo zombala kanye nobumhlophe bezindwangu zekhwalithi ephezulu, izembozo ezinemibala kanye nokuqedwa kokuhlobisa.
3. Ukucubungula okulula, ukonga izindleko nesikhathi Ukugeleza kwamanzi kuvimbela ukuvaleka kwezibhamu zokufafaza. Akukho mishini ekhethekile yokuhlakazeka edingekayo ukuze kuxutshwe. Kwenza kube lula ukuhamba komsebenzi, kunciphisa ukutshalwa kwezimali kanye nokuthuthukisa ukusebenza kahle emigqeni ezenzakalelayo.
4. Ukusebenza kahle kakhulu ekulayisheni okuphansi Ukusebenzisana okuqinile nama-halogenated retardants. Ukusebenza kahle kakhulu ku-3:1 halogen/antimony molar ratio. Ukwengezwa okuphansi kufinyelela amazinga aphezulu omlilo, kwengeza isisindo esincane kanye nokugcina ukuthungwa. Kufanelana nezicelo ezifunwa kakhulu njenge-CCL, i-polyester/epoxy/phenolic resins.
5. Inobungani nemvelo futhi iyahambisana nemithetho. Isekelwe emanzini ahlanzekile, ayinazo izinyibilikisi. Akukho ukukhishwa okuyingozi ngesikhathi sokusetshenziswa. Ihambisana nemithetho ye-EU REACH kanye nemithethonqubo yezemvelo yomhlaba wonke. Okungeyona i-PBT/vPvB. Ukuthuthwa okuphephile, ukugcinwa kanye nokuphathwa ngezitifiketi ezigcwele zezimboni.
Izinzuzo Ezikhethekile ze-UMCAP46 (Ibanga Le-Modacrylic Fiber)
1. I-nano-morphology eqinile yokukhiqizwa kwefayibha. Ukusabalala kwe-nano-Sb₂O₅ okufanayo, okungahlanganisiwe kuhlangabezana nezidingo eziqinile zosayizi wezinhlayiya zokukhiqizwa kwefayibha ye-modacrylic.
2. Ukuhambisana okugcwele ne-DMAC Kwenzelwe i-DMAC (N,N-dimethylacetamide, CAS: 127-19-5) — isithako esiyinhloko ekukhiqizweni kwefayibha ye-modacrylic. Akukho ukuhlukaniswa kwe-sedimentation/phase; kulondoloza ukuqina kwe-solvent. Kuqinisekisa ukukhiqizwa okuqhubekayo kanye nesivuno esikhulu.
3. Ukusebenza kwemakethe okuqinisekisiwe, ukushintshwa okufanele kakhulu Kwamukelwe ngempumelelo ngobuningi ngabakhiqizi be-modacrylic fiber abaphambili eNingizimu-mpumalanga ye-Asia naseMpumalanga Ephakathi, kuthatha indawo ye-NYACOL A1550 ngokuphelele. Ihambisana nokusebenza ngezindleko eziphansi; ihambisana nezinqubo zendawo kanye nezindinganiso zemvelo. Ukunikezwa ngobuningi okuthembekile.

Isiqinisekiso Sobungcweti: Ukulawulwa Kwekhwalithi Nokusekelwa Komhlaba Wonke
I-UrbanMines Tech igcina uhlelo lokuphatha ikhwalithi oluqinile. I-UMCAP38/46 ihlolwa ngokuqinile efektri, ngemingcele ebalulekile (okuqukethwe kwe-Sb₂O₅, i-viscosity, amandla adonsela phansi athile, i-pH, ukungcola) okudlula amazinga embonini nokuqinisekisa ukuhambisana kwe-batch-to-batch.
Ukwenza ngokwezifiso kuyatholakala: usayizi wezinhlayiya olungiselelwe wena, i-pH kanye nokuhlushwa. Sinikeza isiqondiso sokwakheka kobuchwepheshe kanye nokusekelwa kwangemva kokuthengisa ukusiza amakhasimende ukuthi afinyelele ekushintsheni ukungenisa, athuthukise ukusebenza futhi anciphise izindleko.
Khetha i-UMCAP38/46 ukuze uthole isisombululo se-colloidal antimony pentoxide esisebenza kahle kakhulu, esizinzile, esingabizi kakhulu — okuyindlela engcono kakhulu kunemikhiqizo yase-US, ehambisana nezitayela zomhlaba wonke ze-flame retardant ezinobungani nemvelo.
