Izinto ezivimbela ilangabi ziyizithasiselo ezibalulekile ezisetshenziswa ezintweni ezahlukahlukene, ikakhulukazi amapulasitiki, ukunciphisa ukusha nokuthuthukisa ukuphepha komlilo. Njengoba isidingo semikhiqizo ephephile sanda, ukuthuthukiswa nokusetshenziswa kwezinto ezivimbela ilangabi kuye kwashintsha kakhulu. Lesi sihloko sihlola izinhlobo ezahlukene zezinto ezivimbela ilangabi ezivame ukusetshenziswa kumapulasitiki, izindlela zazo zokusebenza, kanye nemiphumela yazo emvelweni.
Ama-halogenated flame retardants aphakathi kwezinto ezisetshenziswa kakhulu embonini yepulasitiki. Lawa ma-compound aqukethe i-bromine noma i-chlorine futhi ayasebenza ekuphazamiseni inqubo yokusha. Uma evezwa ekushiseni, akhipha ama-athomu e-halogen asabela nama-free radicals elangabini, acime umlilo ngempumelelo. Izibonelo ezivamile zifaka phakathi i-tetrabromobisphenol A (TBBPA) kanye nama-polybrominated diphenyl ethers (PBDEs). Nakuba esebenza kahle, ukukhathazeka ngokuqhubeka kwawo endaweni ezungezile kanye nezingozi zempilo ezingaba khona kuholele ekuhlolweni nasekulawulweni okukhulu.
Izinto ezivimbela ilangabi ezisekelwe ku-phosphorus ziyathandwa ngenxa yokusebenza kwazo kahle kanye nomthelela ophansi emvelweni uma kuqhathaniswa nezinketho ze-halogenated. Lezi zinhlanganisela zingahlukaniswa ngezinhlobo ezimbili eziyinhloko: ezisabelayo kanye nezingeziwe. Izinto ezivimbela ilangabi ze-phosphorus ezisebenzayo zibopha ngamakhemikhali ne-polymer ngesikhathi senqubo yokukhiqiza, kuyilapho izinhlobo zezengezo zihlala zixubene ngokomzimba ngaphakathi kwepulasitiki. Izibonelo zifaka phakathi i-triphenyl phosphate (TPP) kanye ne-ammonium polyphosphate (APP). Zisebenza ngokukhuthaza ukwakheka kwe-char, okusebenza njengesithiyo ekushiseni nasemoyeni, ngaleyo ndlela kunciphise ukusha.
Izinto ezivimbela ilangabi ezingaphili, njenge-aluminium hydroxide kanye ne-magnesium hydroxide, ziyizindlela ezingezona ezinobuthi futhi ezinobungani nemvelo. Lezi zinhlanganisela zikhipha umhwamuko wamanzi uma zishiswa, ezipholisa izinto futhi zinciphise amagesi avuthayo. Zivame ukusetshenziswa ezisetshenziswa lapho ukuphepha kubaluleke kakhulu, njengakumadivayisi kagesi nawe-elekthronikhi. Nakuba zingasebenzi kahle emazingeni okushisa aphansi uma kuqhathaniswa nezinto ezivimbela ilangabi ezisekelwe ku-halogenated noma ku-phosphorus, iphrofayili yazo yokuphepha izenza zibe ukukhetha okuthandwayo ezisetshenziswa eziningi.
Izinto ezivimbela ilangabi ezingaphakathi zihlukile ngoba ziyanda lapho zivezwa ekushiseni, zakha ungqimba lwe-char oluvikela izinto ezingaphansi emalangabini. Lolu hlobo lwe-flame retardant luvame ukuba nenhlanganisela yomthombo wekhabhoni, umthombo we-asidi, kanye ne-ejenti yokuvunguza. Uma ishiswa, umthombo we-asidi uvuselela umthombo wekhabhoni ukuze wakhe i-char, kuyilapho i-ejenti yokuvunguza idala amabhamuza egesi andisa ungqimba lwe-char. Le ndlela inikeza ukuvikelwa komlilo okuhle kakhulu futhi ivame ukusetshenziswa ekumbozweni nasepulasitikini eguquguqukayo.
Nakuba izinto ezivimbela umlilo zidlala indima ebalulekile ekuthuthukiseni ukuphepha komlilo, ukusetshenziswa kwazo kuphakamisa ukukhathazeka okukhulu kwezemvelo kanye nempilo. Izinto eziningi ezivimbela umlilo ezifakwe i-halogen ziye zahlotshaniswa nemiphumela emibi yezempilo, okuhlanganisa ukuphazamiseka kwe-endocrine kanye nezinkinga zokuthuthukiswa. Ngenxa yalokho, izinhlangano ezilawulayo ziya ngokuya zinciphisa ukusetshenziswa kwazo. Ngokuphambene nalokho, izinto ezivimbela umlilo ezingaphili ngokuvamile zibhekwa njengezinye izindlela eziphephile, yize ucwaningo oluqhubekayo luyadingeka ukuze kuqondwe ngokugcwele imiphumela yazo yesikhathi eside.
Ukukhethwa kwezinto ezivimbela ilangabi kumapulasitiki kuthonywa izici ezahlukahlukene, okuhlanganisa ukusebenza kahle, ukuphepha, kanye nomthelela emvelweni. Njengoba imithethonqubo iqina futhi ukuqwashisa kwabathengi kukhula, imboni cishe izoqhubeka nokushintshela ezinkethweni ezivikela ilangabi eziphephile nezisimeme. Ukuqonda izinhlobo ezahlukene zezinto ezivimbela ilangabi kanye nezindlela zazo kubalulekile kubakhiqizi, abathengi, kanye nabenzi bezinqubomgomo ngokufanayo ekufuneni izinto eziphephile.
I-Sichuan Taifeng New Flame Retardant Co., Ltdungumkhiqizi onolwazi lweminyaka engama-22 ogxile ekukhiqizweni kwe-ammonium polyphosphate flame retardants, ama-prouducts ethu athunyelwa kabanzi kwamanye amazwe.
I-retardant yethu yomlilo emeleI-TF-241ilungele imvelo futhi iyonga, inokusetshenziswa okuvuthiwe ku-PP, PE, HEDP.
Uma udinga ukwazi ulwazi olwengeziwe, sicela usithinte.
