I-Colloidal Antimony Pentoxide Flame Retardant esebenzayo kakhulu: UMCAP38 kunye ne-UMCAP46 – Indawo ekhethwayo yokuyitshintsha
Ngokuchasene nokuphuculwa kwe-flame retardant yehlabathi kunye nemigangatho engqongqo yokusingqongileyo, i-colloidal antimony pentoxide (CAP) iye yaba yinto ephambili edibanisa i-flame retardant kwiingubo, amalaphu, ii-resins kunye neefayibha zokwenziwa, ngenxa yokusebenza kwayo okuphezulu, impembelelo ephantsi kunye nobuhlobo nokusingqongileyo.
I-UrbanMines Tech, ingcali kwi-R&D kunye nemveliso esekwe kwi-antimony, iqalisa i-UMCAP38 (38% colloidal Sb₂O₅) kunye ne-UMCAP46 (46% colloidal Sb₂O₅). La manqanaba okulinganisa ahambelana ngokuchanekileyo kwaye athatha indawo ye-NYACOL A1540 / A1550 ngokupheleleyo, enikezela ngezisombululo ezingabizi kakhulu nezithembekileyo zokurhoxisa ilangatye kwihlabathi liphela.
Iipropati zeMveliso eziSisiseko: iNano-Colloidal, Umgangatho oQondayo
Zombini ezi ntlobo zi-anionic dispersions ezisekelwe emanzini ezinembonakalo efanayo efana nobisi nomhlophe. Icandelo elisebenzayo yi-nano-scale antimony pentoxide (Sb₂O₅), eveliswa ngenkqubo ye-reflux oxidation ephucukileyo. Ziyamelana nokubola kwaye zigcina uzinzo oluhle kakhulu lokusasazeka phantsi kweemeko eziqhelekileyo. Zilungiselelwe nge-triethanolamine, ziphucula ukucutshungulwa kwazo kwaye zilungele zonke iinkqubo zamanzi kunye nokusetyenziswa kwemizi-mveliso.
UMCAP38: Umxholo we-Sb₂O₅ ≥38%. Ihambelana ne-NYACOL A1540. Isebenziseka lula kwiimpahla, kwiingubo kunye neeresini.
UMCAP46: Umxholo we-Sb₂O₅ ≥46%. Imo ye-nano-particle elawulwayo. Yenzelwe iifayibha ze-modacrylic, ithatha indawo ye-NYACOL A1550. Yenziwe ngobuninzi ngabavelisi abaphambili beefayibha ze-modacrylic kuMzantsi-mpuma we-Asia nakuMbindi Mpuma.
Iingenelo Eziphambili: Ukusebenza Okugqwesileyo Kwiimfuno Zemizi-mveliso
Iingenelo eziBalulekileyo eziBelwana ngazo (UMCAP38 kunye neUMCAP46)
1. Ukungena kwe-nano, akukho lahleko yepropati Amasuntswana anobukhulu be-nano anika ukungena okuhle kakhulu kwe-substrate, adityaniswe nzulu kwiingubo, iifilimu, iifayibha kunye neeresini. Andisa ukulibaziseka komlilo ngaphandle kokuphazamisa amandla oomatshini, ukucaca okanye imbonakalo - ifanelekile ukusetyenziswa okucacileyo kancinci.
2. Inombala ophantsi, igcina umthunzi wokuqala. Ukusasazeka kolwelo okugqwesileyo kuthintela ukutshintsha kombala. Isusa ukutyheli/ukuba mnyama okuqhelekileyo kwizinto ezigcina umbala umdaka, ihlangabezana neemfuno zombala kunye nobumhlophe kwimpahla yexabiso eliphezulu, iingubo ezinemibala kunye nokugqitywa kokuhombisa.
3. Kulula ukucubungula, ukonga iindleko kunye nexesha Ukuguquguquka kwamanzi kuthintela ukuvaleka kwezibhamu zokutshiza. Akukho zixhobo zikhethekileyo zokusasazeka ezifunekayo ekuxubeni. Kwenza kube lula ukuhamba komsebenzi, kunciphisa utyalo-mali lwemali kwaye kwandisa ukusebenza kakuhle kwimigca ezenzekelayo.
4. Ukusebenza kakuhle xa ulayisha kancinci. Ukusebenzisana okunamandla kunye ne-halogenated retardants. Ukusebenza kakuhle kwi-3:1 halogen/antimony molar ratio. Ukongezwa okuphantsi kufezekisa amazinga aphezulu omlilo, kongeza ubunzima obuncinci kunye nokugcina ubume. Ifanela izicelo ezifunwa kakhulu ezifana ne-CCL, i-polyester/epoxy/phenolic resins.
5. Ilungele indalo kwaye iyathobela. Isekelwe emanzini acocekileyo, ayinazinyibilikisi. Akukho kukhutshwa komoya okuyingozi ngexesha lokusetyenziswa. Ithobela i-EU REACH kunye nemigaqo yokusingqongileyo yehlabathi. Ayisiyo-PBT/vPvB. Uthutho olukhuselekileyo, ukugcinwa kunye nokuphathwa ngeziqinisekiso ezipheleleyo zoshishino.
Iingenelo ezikhethekileyo ze-UMCAP46 (iModacrylic Fiber Grade)
1. I-nano-morphology ezinzileyo yokuveliswa kwefayibha. Ukusasazwa kwe-nano-Sb₂O₅ okulinganayo, okungaxutywanga kuyahlangabezana neemfuno ezingqongqo zobukhulu beesuntswana zokwenziwa kwefayibha ye-modacrylic.
2. Ukuhambelana ngokupheleleyo ne-DMAC Yenzelwe i-DMAC (N,N-dimethylacetamide, CAS: 127-19-5) — isinyibilikisi esibalulekileyo kwimveliso yefayibha ye-modacrylic. Akukho sedimentation/phase sepasement; igcina uzinzo lwe-solvent. Iqinisekisa imveliso eqhubekayo kunye nesivuno esiphezulu.
3. Ukusebenza okuqinisekisiweyo kwimarike, ukutshintshwa okufanelekileyo. Yamkelwe ngempumelelo ngabavelisi abaphambili be-modacrylic fiber kuMzantsi-mpuma we-Asia nakuMbindi Mpuma, ithatha indawo ye-NYACOL A1550 ngokupheleleyo. Ihambelana nokusebenza ngexabiso eliphantsi; ihambelana neenkqubo zasekuhlaleni kunye nemigangatho yokusingqongileyo. Ubonelelo oluthembekileyo lwezambuku.
