Ama-flame retardants ayizithasiselo ezibalulekile ezisetshenziswa ezintweni ezahlukahlukene, ikakhulukazi amapulasitiki, ukunciphisa ukuvutha nokuthuthukisa ukuphepha komlilo. Njengoba isidingo semikhiqizo ephephile sikhula, ukuthuthukiswa kanye nokusetshenziswa kwama-flame retardants kuye kwavela kakhulu. Lesi sihloko sihlola izinhlobo ezihlukene zamalangabi e-flame retardants avame ukusetshenziswa kumapulasitiki, izindlela zabo zokwenza, kanye nemithelela yazo yemvelo.
Ama-halogenated flame retardants aphakathi kwezinto ezisetshenziswa kakhulu embonini yepulasitiki. Lezi zinhlanganisela ziqukethe i-bromine noma i-chlorine futhi zisebenza ngempumelelo ekuphazamiseni inqubo yokuvutha. Lapho echayeke ekushiseni, akhulula ama-athomu e-halogen asabela ngama-radicals mahhala elangabini, acime umlilo ngempumelelo. Izibonelo ezijwayelekile zifaka i-tetrabromobisphenol A (TBBPA) kanye ne-polybrominated diphenyl ethers (PBDEs). Nakuba kusebenza kahle, ukukhathazeka mayelana nokuphikelela kwazo kwezemvelo kanye nobungozi bezempilo obungaba khona kuye kwaholela ekwandeni kokuhlolwa nokulawulwa.
Ama-flame retardants asekelwe ku-phosphorus athola ukuthandwa ngenxa yokusebenza kahle kwawo kanye nomthelela ophansi kwemvelo uma kuqhathaniswa nezinketho ze-halogenated. Lezi zinhlanganisela zingahlukaniswa zibe izinhlobo ezimbili eziyinhloko: ezisebenzayo nezingeziwe. Izinqamuleli zamalangabi e-phosphorus ezisebenzayo zihlangana ngamakhemikhali ne-polymer ngesikhathi senqubo yokukhiqiza, kuyilapho izinhlobo ezingeziwe zihlala zixubene ngaphakathi kwepulasitiki. Izibonelo zifaka i-triphenyl phosphate (TPP) ne-ammonium polyphosphate (APP). Asebenza ngokugqugquzela ukwakheka kwe-char, esebenza njengesithiyo ekushiseni nomoya-mpilo, ngaleyo ndlela yehlisa ijubane ukuvutha.
I-Inorganic flame retardants, njenge-aluminium hydroxide ne-magnesium hydroxide, ayizona izindlela ezinobuthi futhi ezihambisana nemvelo. Lezi zinhlanganisela zikhipha umhwamuko wamanzi lapho kushisa, okupholisa izinto futhi kuncibilikise amagesi avuthayo. Avame ukusetshenziswa ezinhlelweni lapho ukuphepha kubaluleke kakhulu, njengakuzinto zikagesi neze-elekthronikhi. Nakuba zingasebenzi kahle emazingeni okushisa aphansi uma kuqhathaniswa ne-halogenated noma i-phosphorus-based retardants, iphrofayili yazo yokuphepha ibenza babe ukukhetha okuthandwayo ezinhlelweni eziningi.
Izinqamuleli zamalangabi e-Intumescent zihlukile ngoba ziyanwebeka lapho zichayeka ekushiseni, zenze isendlalelo se-char esivikelayo esivikela into engaphansi emalangabini. Lolu hlobo lwe-flame retardant ngokuvamile luhlanganisa inhlanganisela yomthombo wekhabhoni, umthombo we-asidi, ne-ejenti efuthayo. Uma ushisisa, umthombo we-asidi ugqugquzela umthombo wekhabhoni ukuze wenze i-char, kuyilapho i-ejenti efuthayo idala amabhamuza egesi anweba isendlalelo se-char. Lo mshini uhlinzeka ngokuvikeleka okuhle kakhulu komlilo futhi uvame ukusetshenziselwa ukumboza namapulasitiki aguquguqukayo.
Nakuba izicishamlilo zidlala indima ebalulekile ekuthuthukiseni ukuphepha komlilo, ukusetshenziswa kwazo kuphakamisa ukukhathazeka okukhulu kwemvelo nempilo. Ama-halogenated flame retardants amaningi aye axhunyaniswa nemiphumela emibi yezempilo, okuhlanganisa ukuphazamiseka kwe-endocrine kanye nezinkinga zentuthuko. Ngenxa yalokho, izinhlangano ezilawulayo ziya ngokuya zikhawulela ukusetshenziswa kwazo. Ngokuphambene, i-phosphorus nama-inorganic flame retardants ngokuvamile abhekwa njengezinye izindlela eziphephile, nakuba ucwaningo oluqhubekayo ludingeka ukuze uqonde ngokugcwele umthelela wazo wesikhathi eside.
Ukukhethwa kwama-flame retardants kumapulasitiki kuthonywa izici ezihlukahlukene, okuhlanganisa ukusebenza kahle, ukuphepha, kanye nomthelela wemvelo. Njengoba imithetho iqina futhi nokuqwashisa kwabathengi kukhula, imboni kungenzeka iqhubeke nokuguqukela ekukhetheni okuphephile, okusimeme kakhudlwana kokuvimbela amalangabi. Ukuqonda izinhlobo ezahlukene zezinqamuli zomlilo kanye nezindlela zazo kubalulekile kubakhiqizi, abathengi, kanye nabenzi benqubomgomo ngokufanayo ekufuneni izinto eziphephile.
I-Sichuan Taifeng New Flame Retardant Co., Ltdingumkhiqizi oneminyaka engama-22 yesipiliyoni esikhethekile ekukhiqizeni i-ammonium polyphosphate retardants flame, imikhiqizo yethu ithunyelwa kabanzi phesheya kwezilwandle.
Omele yethu i-flame retardantTF-241i-eco-friendly futhi iyonga, inesicelo esivuthiwe ku-PP, PE, HEDP.
Uma udinga ukwazi ulwazi olwengeziwe, sicela usithinte.
