Iiretardants zomlilo zizongezo ezibalulekileyo ezisetyenziswa kwizinto ezahlukeneyo, ngakumbi iiplastiki, ukunciphisa ukutsha kunye nokwandisa ukhuseleko lomlilo. Njengoko imfuno yeemveliso ezikhuselekileyo isanda, uphuhliso kunye nokusetyenziswa kweeretardants zomlilo ziye zavela kakhulu. Eli nqaku liphonononga iintlobo ezahlukeneyo ze-flame retardants ezisetyenziswa ngokuqhelekileyo kwiiplastiki, iindlela zabo zokwenza, kunye nefuthe labo lokusingqongileyo.
I-Halogenated flame retardants zezona zisetyenziswa kakhulu kushishino lweplastiki. Ezi zixhobo ziqulethe i-bromine okanye i-chlorine kwaye zisebenza kakuhle ekuphazamiseni inkqubo yokutshisa. Xa bevezwe kubushushu, bakhupha iiathom ze-halogen ezisabela ngeeradicals zasimahla edangatyeni, zicima ngokufanelekileyo umlilo. Imizekelo eqhelekileyo ibandakanya i-tetrabromobisphenol A (TBBPA) kunye ne-polybrominated diphenyl ethers (PBDEs). Ngelixa lisebenza, iinkxalabo malunga nokuzingisa kwazo kokusingqongileyo kunye neengozi zempilo ezinokuthi zikhokelele ekwandeni kophononongo kunye nolawulo.
I-phosphorus-based flame retardants ifumana ukuthandwa ngenxa yokusebenza kwayo kunye nefuthe eliphantsi lokusingqongileyo xa kuthelekiswa nokukhethwa kwe-halogenated. Ezi khompawundi zinokwahlulwa zibe ziindidi ezimbini eziphambili: ezisebenzayo kunye nezongezo. I-phosphorus esebenzayo ibuyisela idangatye kwi-chemical bond kunye ne-polymer ngexesha lenkqubo yokuvelisa, ngelixa iindidi ezongezelelweyo zihlala zixutywe ngokwasemzimbeni ngaphakathi kweplastiki. Imizekelo ibandakanya i-triphenyl phosphate (TPP) kunye ne-ammonium polyphosphate (APP). Basebenza ngokukhuthaza ukubunjwa kwe-char, esebenza njengesithintelo kubushushu kunye ne-oxygen, ngaloo ndlela inciphisa ukutsha.
I-Inorganic flame retardants, efana ne-aluminiyam hydroxide kunye ne-magnesium hydroxide, aziyiyo ityhefu kwaye zinobuhlobo bokusingqongileyo. Ezi khompawundi zikhupha umphunga wamanzi xa ushushu, nto leyo epholisa izinto kunye negesi enokutsha. Zihlala zisetyenziswa kwizicelo apho ukhuseleko lubaluleke kakhulu, njengakwizixhobo zombane neze-elektroniki. Nangona zingasebenzi kakuhle kumaqondo okushisa aphantsi xa kuthelekiswa ne-halogenated okanye i-phosphorus-based retardants, iphrofayili yabo yokhuseleko yenza ukuba kube yinto ekhethiweyo kwizicelo ezininzi.
I-Intumescent flame retardants iyodwa kuba iyakhula xa ibonakaliswe kubushushu, yenze i-char layer ekhuselayo ekhusela izinto ezingaphantsi kwamadangatye. Olu hlobo lwe-flame retardant lubandakanya indibaniselwano ye-carbon source, umthombo we-asidi, kunye ne-agent evuthelayo. Xa kushushu, umthombo we-asidi uvuselela umthombo wekhabhoni ukuba wenze i-char, ngelixa i-arhente evuthelayo idala amaqamza erhasi eyandisa i-char layer. Lo matshini ubonelela ngokhuseleko olubalaseleyo lomlilo kwaye luhlala lusetyenziswa kwiingubo kunye neeplastiki eziguquguqukayo.
Nangona iiretadants zomlilo zidlala indima ebalulekileyo ekwandiseni ukhuseleko lomlilo, ukusetyenziswa kwazo kuphakamisa ukukhathazeka okubalulekileyo kokusingqongileyo kunye nempilo. Uninzi lwe-halogenated flame retardants luye lwadibaniswa nemiphumo emibi yempilo, kubandakanywa ukuphazamiseka kwe-endocrine kunye nemiba yophuhliso. Ngenxa yoko, imibutho elawulayo iyancipha ngakumbi ukusetyenziswa kwayo. Ngokwahlukileyo, i-phosphorus kunye ne-inorganic flame retardants ngokubanzi zithathwa njengezinye iindlela ezikhuselekileyo, nangona uphando oluqhubekayo luyimfuneko ukuqonda ngokupheleleyo iimpembelelo zabo zexesha elide.
Ukukhethwa kweeretadants zomlilo kwiiplastiki kuphenjelelwa zizinto ezahlukeneyo, kubandakanya ukusebenza kakuhle, ukhuseleko, kunye nefuthe lokusingqongileyo. Njengoko imimiselo iqina kunye nokuqonda kwabathengi kukhula, ishishini linokuthi liqhubeke litshintshela kwiinketho ezikhuselekileyo, ezizinzileyo zokunqanda amadangatye. Ukuqonda iintlobo ezahlukeneyo zeeretardants zomlilo kunye neendlela zazo zibalulekile kubavelisi, abathengi, kunye nabenzi bomgaqo-nkqubo ngokufanayo ekufuneni izinto ezikhuselekileyo.
