Ukulinganisa okunembile kwezinto eziyisisekelo kusekela ukuhambisana nokuphepha komlilo emhlabeni wonke kanye nezindinganiso zobuthi zezithasiselo ezivimbela umlilo epulasitikini evimbela umlilo kanye nerabha evimbela umlilo. Imiphumela yokuhlaziya kumele iqinisekise okuqukethwe okuqondile kwe-aluminium hydroxide flame retardant kanye nezinye izinto ezibalulekile. Imithethonqubo e-EU naseNyakatho Melika iyalela imikhawulo ephezulu yezinto eziyingozi; kukhona imikhawulo engu-0.01–0.1% w/w yezinto ezifana nezinsimbi ezisindayo kuma-polymer matrices.
Ukulawulwa okuqinile kwezinto eziyisisekelo kuqinisekisa ukusatshalaliswa okufanayo kwezinto zokugcwalisa i-aluminium ku-polymer yomnikazi. Ukusatshalaliswa okufanayo kwe-aluminium filler ye-alloys kanye nezinhlelo zokusebenza ezihlanganisiwe kukhulisa ukusebenza kahle kwesithiyo, kuqinisekisa ukucindezelwa okuqhubekayo kokusha kanye nokusabalala komlilo.

Izinqubo Ezibalulekile Zezimboni Ezihilela I-Aluminium Filler kanye Nezithibi Zomlilo
I-aluminium hydroxide flame retardant ibola ngokweqile ngaphezu kwama-200°C, ikhipha umhwamuko wamanzi futhi yakhe insalela ye-aluminium oxide. Le nqubo imunca ukushisa, ipholise i-matrix, futhi inciphise amagesi avuthayo, abalulekile epulasitikini evimbela umlilo kanye nerabha evimbela umlilo. Ama-formulations anama-nanoplate e-aluminium hydroxide kanye nezithasiselo ze-intumescent flame retardant afinyelela izilinganiso ze-UL-94 V-0 futhi anciphisa amanani enkomba ye-oxygen afinyelela ku-31.1%. Kurabha ye-nitrile, i-aluminium hydroxide engu-2 wt% ikhulisa ukwakheka kwe-char kanye nokuzinza kokushisa ngokwenziwa kwe-phosphate ye-in situ.
Izithasiselo ezivimbela ilangabi zinciphisa ukusha kanye nokukhishwa kokushisa ngokuthuthukisa izendlalelo ze-char ezivikelayo ezicebile nge-aluminium phosphate. Izinto zokugcwalisa i-aluminium, ezilungiselelwe usayizi wezinhlayiya kanye nokwakheka kwazo, zithuthukisa imiphumela yokuvimbela kanye nezakhiwo zemishini kumapulasitiki nakuma-raber. Ukugcwalisa i-aluminium okuhlala njalo kwama-alloy kanye nokugcwalisa i-aluminium ukuze kulungiswe insimbi kusekela ukumelana nomlilo okubikezelwayo kanye nokusebenza kwezinto. Izinqubo zezimboni zihlanganisa lezi zigcwalisi ukuthuthukisa ukuvimbela ilangabi, ukukhuthazela, kanye nokuphepha kwemvelo emikhiqizweni yokugcina.
Izinselele Ekulawulweni Kwekhwalithi Ye-Aluminium Filler
Isigcwalisi se-aluminium se-alloys, ipulasitiki evimbela umlilo, kanye nerabha evimbela umlilo idinga ukwakheka kwamakhemikhali okunembile ukuze kugcinwe ukusebenza okufanayo. Ukuguquguquka kwamazinga okuvimbela umlilo e-aluminium hydroxide kungashintsha imingcele yokushisa futhi kunciphise ukusebenza kahle kwezithasiselo ezivimbela umlilo. Ukuphambuka okungaphezu kuka-0.5% ekugxilweni kwe-aluminium kanye ne-magnesium kuthinta kakhulu amazinga okukhishwa kokushisa, okuthinta ukuphindaphindeka kokuvimbela umlilo.
Ukungalingani kwezinto zokugcwalisa i-aluminium ngeqembu kuphazamisa ukuhlanganiswa okufanayo okudingekayo ukuze kube nomphumela omuhle kakhulu wokuvimbela ezinhlanganisela. Idatha yokukhiqiza ikhombisa ukuguquguquka okufika ku-12% ekusakazweni kwezigcwalisi ngaphakathi kwerabha evimbela umlilo yezentengiselwano ngaphandle kokulawulwa kwekhwalithi okujwayelekile. Lokhu kungahambisani kunganciphisa amandla omshini futhi kukhuphule amazinga okwehluleka ngaphansi kokucindezeleka komlilo.
Izinto ezingcolisayo, okuhlanganisa insimbi, ithusi, kanye nomthofu, zonakalisa ukufudumala kukagesi kanye nokuthembeka kwemishini. Izinsimbi ezisindayo ezidlula i-50 ppm zephula amazinga anobuthi futhi zibeka engcupheni ukuphepha komlilo emikhiqizweni yokugcina. Ukuze kulungiswe insimbi nge-aluminium filler, ngisho nokungcola okuncane kunciphisa ubuqotho bokubopha kanye nokuphila isikhathi eside kokusebenza. Amanani angaphezu kwemingcele yokulawula aveza izingozi zomthetho nezokusebenza.

Ukuhlolwa Okungonakalisi kwe-XRF: Isimiso kanye Nezinzuzo Ekulawulweni Kwefomula
Abahlaziyi be-alloy be-XRF bathola futhi balinganise izinto ezinkulu nezilandelanayo ezintweni zokugcwalisa i-aluminium ngemizuzwana besebenzisa i-X-ray engaxhunyiwe. I-XRF ehlakazayo yamandla ilinganisa ama-X-ray acacile, inquma ngokunembile i-aluminium, i-magnesium, i-silicon, kanye nokungcola okubalulekile ezithasiselweni ezivimbela umlilo. I-XRF analyzer ephathekayo yezinsimbi ivumela ukuqinisekiswa kwezinto zesikhathi sangempela ezigabeni ezibalulekile ekukhiqizweni kwepulasitiki evimbela umlilo kanye nerabha evimbela umlilo. Abaqhubi bahlola ama-batch e-aluminium hydroxide flame retardant ngaphandle kokusika, ukuncibilikisa, noma ukushintsha amasampula, balondoloze ubuqotho futhi bavumele ukuhlolwa okuphindaphindiwe. Umphumela ojwayelekile ukuhlolwa okukodwa ngomzuzu, okusekela ukungenelela okusheshayo ekuphambukeni kwenqubo. Abahlaziyi be-XRF bokwakheka kwensimbi banciphisa ukulahlekelwa kwezinto zokusetshenziswa kanye nezidingo zomsebenzi ngokufaka esikhundleni sezindlela zamakhemikhali ezimanzi ezibhubhisayo. I-Lonnmeter XRF alloy analyzer ivumela ukuhlaziywa kwezinto zesakhiwo ukuqinisekisa ikhwalithi ehambisanayo ye-aluminium filler yama-alloy, ama-composites, kanye ne-aluminium filler yokulungisa insimbi, ukuqinisekisa ukuhambisana nemininingwane yokusebenza kwe-flame retardant kanye nemikhawulo yensimbi esindayo elawulayo.
Ukulawula Okunembile nge-Lonnmeter XRF Alloy Analyzer
I-Lonnmeter XRF alloy analyzer yenza isilinganiso se-aluminium, i-magnesium, i-silicon, nezinye izinto ezengeziwe ezithasiselweni ezigcina ilangabi. I-XRF analyzer ephathekayo yezinsimbi inikezakunembileukufundwa, okuvumela ukuqinisekiswa kokuqukethwe kwe-aluminium hydroxide efanele kupulasitiki ebamba umlilo kanye nerabha ebamba umlilo. Abahlaziyi be-XRF bokwakheka kwensimbi baqinisekisa ukulingana kwebhetshi futhi bembula ukungcola ku-aluminium filler yama-alloys, ama-composites, kanye ne-aluminium filler yokulungisa insimbi.
Ukunemba kokulinganisa kwezinto ezikhanyayo—i-Al, i-Mg, i-Si—kufinyelela0.001ubungako%ngaphansi kwemizuzwana engama-60 ngesampula ngayinye. Isofthiwe isebenzisa ukulinganisa okuthuthukisiwe kanye nokulinganisa i-matrix ukuze kuchazwe ngokunembile ukuvimbela umlilo ngaphakathi kwemikhawulo yokulawula. Idatha ephindaphindwayo nenembile kakhulu isekela ukulawulwa kwenqubo yezibalo (i-SPC) kanye nezinqubo zokuqinisekisa ikhwalithi.
Cela Isilinganiso se-Lonnmeter XRF Alloy Analyzer
Abahlaziyi be-alloy be-Lonnmeter XRF bahlinzeka ngokulinganisa okuyisisekelo okungonakalisi izithasiselo ezivimbela umlilo ekukhiqizweni kwepulasitiki evimbela umlilo kanye nerabha evimbela umlilo. I-XRF analyzer ephathekayo yezinsimbi ilinganisa izinto ezinkulu nezincane, okuhlanganisa i-aluminium ne-magnesium. Ukuhlaziywa okusheshayo kwephuzu elilodwa, ngokuvamile ngaphansi30imizuzwana, ivimbela ukuxubana okunephutha kanye nokungcola kwe-cross-batch ekukhiqizweni kwezinto zokugcwalisa i-aluminium.
Ukuhlanganiswa okuqondile nesofthiwe yokulawula inqubo yezibalo kwenza kube lula ukuthobela yonke imithetho ye-aluminium filler yama-alloy, i-aluminium filler yokulungisa insimbi, kanye nokusetshenziswa kwe-aluminium hydroxide flame retardant. Ukubika okuzenzakalelayo kunikeza ukuqinisekiswa okusheshayo ngokumelene nokuphepha komlilo kanye nemithetho yobuthi ngebhetshi ngayinye, kunciphisa ingozi yokukhunjulwa komkhiqizo kanye nomthwalo wemibhalo. Ukuhlolwa kokungcola kwesikhathi sangempela kuqinisekisa ukuthi ukusetshenziswa kwe-aluminium hydroxide kuma-flame retardants kuhlangabezana kokubili nokuhlanzeka kanye nokucaciswa kwe-homogeneity. Abahlaziyi be-XRF bokwakheka kwensimbi banciphisa ukulahlekelwa komkhiqizo, basekela ukulungiswa okusheshayo kwefomula, futhi bathuthukise ukulawulwa kwezindleko zemisebenzi ephezulu.
