I-Flame Retidant ye-Melamine ye-chumine

I-Melamine Sceanurate(MCA) is a commonly used environmentally friendly flame retardant, widely used in polymer materials such as polyamide (Nylon, PA-6/PA-66), epoxy resin, polyurethane, polystyrene, polyester (PET, PBT), polyolefin and halogen- I-wire yasimahla kunye nentambo. Iipropathi zayo ezihlekisayo zedangatye, ityhefu esezantsi kunye nokuzinza komzimba okufanelekileyo kwenze ukuba ichaphazeleka kakhulu kwaye isetyenziswe kwicandelo le-elektroniki, iimoto kunye nolwakhiwo.

I-Melamine Cwaidirate yintambo eyenziwe yindlela yokuphendula ye-melamine ne-cyaniric acid. Ubume be-molecular ye-molecular eyenziwe yi-hydrogen bound inezinto ezityebileyo zenitrogen. Oku kuvumela i-melamine cycurate cy yokukhupha isixa esithile se-nitrogen kwiqondo lobushushu eliphezulu, ngaloo ndlela kuthintelayo ukusasazeka kwamadangatye. Ulwakhiwo lwayo lwekhemikhali lubonisa ukuba luzinzo oluhle kakhulu, ukomelela koomatshini kunye nefuthe lokuhlawula ilangazelelo.

Ukongeza, i-MCA ayinazo izinto eziyingozi ze-halogn, ke isetyenziswe ngokubanzi amaxesha amaninzi ngeemfuno eziphezulu zendalo esingqongileyo kunye neemfuno zempilo, ngakumbi kwizixhobo zekhaya, izixhobo zokwakha kunye nezixhobo.

 

I-Flame Retidant ye-Melamine ye-chumine

Indlela yokuhlawula ilangatye ye-Melamine ye-cyAmine iboniswa ikakhulu kwiimpawu zayo zokungalunganga kumaqondo obushushu aphezulu kunye nefuthe le-Carbon Maker kwi-Calbon Forviamication. Ngokukodwa, isiphumo esibuyiselekileyo sedabha ye-MCA sinokuhlaziywa kwezi zinto zilandelayo:

(1) ukukhutshwa kwe-nitrogen ukunqanda ubonelelo lweoksijini

Iimolekyuli ze-MCA ziqukethe inani elikhulu le-nitrogen. Ngexesha lenkqubo yokufudumeza, izinto ze-nitrogen ziya kukhutshelwa ukuba zenze irhasi (ikakhulu igesi ye-nitrogen). Igesi ye-nitrogen ngokwayo ayixhasi i-quation, ukuze isebenzisene ngempumelelo i-Oxygen Moder ejikeleze umthombo womlilo, kwaye inciphise iqondo ledangatye, kwaye ke linciphise ukusasazeka kwe-quation. Le nkqubo ibaluleke kakhulu ekuphuculeni iipropathi ezihlawulelwayo zedangatye lezinto, ngakumbi phantsi kweemeko zobushushu obuphezulu.

(2) Ukukhuthaza ukwenziwa komkhenkce wekhafu

Ngexesha lenkqubo yePyrolysis, i-MCA iza kuyenza kwaye ivelise umaleko wekhampasi ngexesha lokuhombisa okukhohlakeleyo. Olu gama le-Inert ye-Inibbonned lunezinto ezibalaseleyo ze-inshurensi kwaye zinokwenza umqobo phakathi kwendawo evuthayo kunye nendawo enganyangekiyo, ukuthintela ukutshintshela kobushushu kunye nokunciphisa ukusasazeka kwedangatye.

Ukongeza, umaleko we-carbbonned unokukhetha ioksijini emoyeni, esenza umaleko okhuselayo, ukunciphisa umfowunelwa weoksijini kunye nezokudibana, ngokuthintela ukudibanisa. Ukuqulunqwa kunye nokuzinza kolu lwangqa lwe-carboning sisitshixo sokuba i-MCA ingayidlalisa ngempumelelo indima njengelangatye.

(3) Ukuphendula kwamachiza kuvelisa umphunga wamanzi

Phantsi kwemeko yobushushu obuphezulu, i-MCA iya kufikelela kwi-Dearaction Reaction kwaye ikhuphe inani elithile lomphunga wamanzi. Umphunga wamanzi unokunciphisa ngokufanelekileyo ubushushu bendawo kwaye basuse ubushushu ngokuphuma, ngaloo ndlela kupholisa umthombo womlilo. Ukongeza, ukumiliselwa komphunga wamanzi kunokunciphisa uxinzelelo lweoksijini ejikeleze umthombo womlilo, okuthintela ukusasazeka kwamalangatye.

(4) Ifuthe lokudibana nezinye izongezo

Ukongeza kwifuthe lokuhlawula ilangatye, i-Melamine Cwaycurate inokukwenza nokunyelisa ngenye indawo yokuhlala okanye i-finlers yokuphucula iipropathi zedangatye lesemba. Umzekelo, i-MCA ihlala isetyenziswa ngokudibeneyo ne-Plasdis yeFolmesis, iifilimu ze-inrganic, njl njl.

 

Izibonelelo kunye nokusetyenziswa kwe-Cleamine ye-cyAnurate

(1) Indalo inobuhlobo kwaye ingenatyhefu

Xa kuthelekiswa ne-Holomen Heardsi Heardyants, i-MCA ayikhuphi i-haloardes eyenzakalisayo ye-halogn (enje nge-hydrogen phermide, i-hydrogen bromide, njl. Njl.) Ngexesha lenkqubo yokuhlala yedangatye, ukunciphisa ungcoliseko kwimpilo yabantu. Inkqubo yokukhutshwa kwe-nitrogen ye-MCA ikhuselekile, ngoko ke ibenobuhlobo ngakumbi ngexesha lokusetyenziswa kwaye inegalelo elingaphantsi kwendalo esingqongileyo.

(2) Uzinzo olufanelekileyo kunye nokuchasana kwemozulu

I-MCA inozinzo oluphakamileyo kwe-thermal, inokugcina iipropathi ezizinzileyo kubushushu obuphezulu, kwaye kuthintele ngokufanelekileyo ukudibanisa okubangelwa ngamaqondo obushushu aphezulu. Kumanye iindawo zokusebenza kobushushu obuphezulu, i-MCA inokubonelela ngokhuseleko oluhlala ixesha elide njengelangatye eliyintloko.

Ukongeza, i-MCA ikwaxhathisa imozulu eyomeleleyo, inokugcina intsebenzo elungileyo ekusebenziseni ixesha elide, kwaye ilungelelanise kwiimeko ezahlukeneyo zemozulu.

(3) Umsi ophantsi

I-MCA ivelisa umsi omncinci xa uvutha kubushushu obuphezulu. Xa kuthelekiswa ne-Holomen HeardEn Flaments, inokunciphisa kakhulu ukukhutshwa kweegesi ezinetyhefu kwimililo kwaye kunciphise ingozi yomsi kubasebenzi.

 

Njengomntu onobuhlobo kwaye ongenabungoziilangatye liyithobekile, I-Melamine Cwarate inendlela ehleliweyo yelangatye ebonakalayo ebonisa uluhlu olubanzi lwamalungelo amasicelo kwizixhobo zanamhlanje. Ngokuphuculwa okuqhubekayo kokukhusela okusingqongileyo kunye neemfuno zokhuseleko, i-Cleamine Cysurate iya kusetyenziswa kwimimandla emininzi kwaye ibe yenye yezona zinto ziphambili zeflethi yokuthenga ilangatye.
