Ukushiswa kwama-polymers kuyindlela yokusabela kwe-oxidation yokushisa enamandla kakhulu futhi eyinkimbinkimbi, ebonakala ngokukhishwa kwentuthu noma ilangabi elivuthayo. Izinto ezivimbela ilangabi ziyisigaba sezithasiselo ezivimbela ukushiswa kwamapulasitiki noma zivimbele ukusabalala kwelangabi. Umphumela wezinto ezivimbela ilangabi wezinto ezivimbela ilangabi ukuvimbela noma ukuvimbela izinga lokushintsha okungokwenyama noma kwamakhemikhali enkambisweni yokushiswa kwezinto ze-polymeric. Ngokukhethekile, umphumela wezinto ezivimbela ilangabi ubonakala kakhulu kulezi zici ezilandelayo.
I-flame retardant kunqubo yokuvutha kwe-polymer yomphumela wokubuyiswa komlilo:
I-flame retardant retardant - umphumela wokumunca ukushisa
Iqhaza lomphumela wokumunca ukushisa ukwenza ukukhuphuka kwezinga lokushisa kwe-polymer kwenzeka ngobunzima.
Isibonelo, i-borax inama-molecule angu-10 wamanzi e-crystalline, njengokukhululwa kwamanzi e-crystalline ukuze athwebule u-141.8kJ/mol wokushisa, ngakho ukumuncwa kokushisa ukuze ukukhuphuka kwezinga lokushisa kwento kuvinjwe, okuholela kumphumela we-flame retardant.
I-flame retardant retardant - umphumela wokumboza
Umphumela uwukukhiqiza ungqimba oluzinzile lwesembozo emazingeni okushisa aphakeme noma ukubola ukuze kukhiqizwe into efana negwebu evala ingaphezulu lempahla ye-polymeric. Lokhu kwenza kube nzima ukuthi ukushisa okudalwe ukusha kungene ngaphakathi kwento futhi namagesi avuthayo akhiqizwa ukubola okushisayo kwento ye-polymer ukuthi abaleke. Isebenza njengesithiyo somoya ezintweni, ngaleyo ndlela ivimbele ukuqhekeka kwempahla futhi izuze umphumela wokunqanda ilangabi.
I-flame retardant retardant - umphumela wokunciphisa
Lezi zinto zingakhiqiza inani elikhulu legesi elingashi lapho lichithwa ukushisa, ukuze igesi evuthayo ekhiqizwe into ye-polymer kanye ne-oksijeni emoyeni ihlanjululwe futhi ingafinyeleli ebangeni lokuhlushwa elivuthayo.
I-flame retardant retardant - umphumela wokudlulisa
Umphumela uwukushintsha imodi yokubola okushisayo kwezinto ze-polymer, ngaleyo ndlela kuvimbela ukukhiqizwa kwamagesi avuthayo.
I-flame retardant flame retardant - umphumela wokuvimbela
Ukubamba okuphakathi okusebenzayo kokusabela kokusha, okufana ne-HO- ne-H-, kuvimbela ukusabela kwe-radical chain yamahhala futhi kunciphisa izinga lokuvutha kuze kube yilapho ilangabi licisha.
I-flame retardant retardant - umphumela wokuthuthukisa
Ezinye izinto ezisetshenziswayo azinawo umthelela we-flame retardant uma zisetshenziswa zodwa noma zinomphumela omncane we-flame retardant, kodwa izinto ezihlukahlukene zingasetshenziswa ukuthuthukisa umthelela we-flame retardant, njenge-antimony trioxide nezinhlanganisela ze-halogen ezisetshenziswa ndawonye.
Indlela yokuvimbela ilangabi enqubweni yokusha kwe-polymer:
Indlela yokubuyisela amalangabi - indlela yokubuyisela amalangabi esigabeni segesi
Amasistimu wokubuyiswa komlilo wesigaba somhwamuko abhekisela emthelela wokuvimbela ilangabi lokuphazamisa noma lokuhlehlisa ukusabela kokusha kweketango esigabeni segesi. Ukuncipha kwelangabi lesigaba se-vapor ikakhulukazi kuhlanganisa:
- Ama-radical inhibitor amahhala akhiqizwa lapho okokusebenza kwe-flame retardant kushiswa noma kushiswa, ngaleyo ndlela kuphazamise ukusabela kweketango lomlilo.
- Ukukhiqizwa kwezinhlayiya ezinhle lapho okokusebenza kwe-flame retardant kubaswa noma kushiswa, okukhuthaza ukuboshwa kwama-radicals mahhala ukunqamula ukusabela kokusha kweketango.
- Ukukhishwa kwenani elikhulu legesi engenzi lutho noma umhwamuko ophezulu lapho into ebambezela ilangabi ishiswa noma ishiswa.
Izindlela zokunqanda amalangabi - izindlela zokunqanda amalangabi esigaba esijiyile
Ukuncipha kwelangabi lesigaba esijiyile kubhekisela emthelela wokubuyiswa kwelangabi okhiqizwa ngokubambezeleka noma ukuphazamisa ukubola okushisayo kwezinto ezibamba ilangabi esigabeni esijiyile. Ukuncipha komlilo wesigaba esijiyile ikakhulukazi kuhlanganisa:
- Ama-retardants amalangabi abuyisela emuva noma aphazamise ukubola okushisayo kwamagesi avuthayo nama-radicals angakhiqizwa phakathi nenqubo yokuhlangana.
- Izihlungi ze-Inorganic ezinamandla amakhulu okushisa akhethekile ezintweni ezingabambezeli ilangabi, okwenza izinto ezisetshenziswayo zibe mancane amathuba okuba zifinyelele izinga lokushisa lokubola ngokugcina ukushisa kanye ne-thermal conductivity.
- Ukubola okushisayo kwe-flame retardant kubamba ukushisa, ukuze ukunyuka kwezinga lokushisa kwento ebuyisela ilangabi kwehliswe noma kumiswe okwesikhashana.
- Lapho into ebambezela ilangabi ivutha, ikhiqiza ungqimba lwekhabhoni enezimbotshana ebusweni bayo, okunzima ukuyishisa, ivikela ukushisa nomoya-mpilo, futhi ivimbele igesi evuthayo ukuba ingangeni esigabeni segesi.
Indlela yokubuyisela amalangabi - ukuphazamiseka kwendlela yokubuyisela amalangabi okushintshanisa ukushisa
Indlela yokubuyisela amalangabi eshintshile ephazamisekile isho ukuthi ingxenye yokushisa ekhiqizwe ukushiswa kwezinto ezibushela ilangabi iyasuswa, ukuze impahla ingakwazi ukugcina izinga lokushisa elishisayo lokubola futhi ngenxa yalokho ayikwazi ukugcina ukukhiqizwa kwamagesi avuthayo, ngakho-ke ukuvutha kuyazicisha.
