Sai dai ƴan samfuran roba na roba, yawancin samfuran roba, kamar roba na halitta, kayan wuta ne ko masu ƙonewa.A halin yanzu, manyan hanyoyin da ake amfani da su don inganta jinkirin harshen wuta, sune ƙara abubuwan da ke hana wuta ko kuma masu cike da wuta, da kuma haɗawa da gyarawa da kayan hana wuta.Akwai nau'ikan fasahohin hana wuta da yawa don roba:
1. Hydrocarbon roba
Hydrocarbon roba ya hada da NR, SBR, BR, da dai sauransu. Hydrocarbon roba gaba ɗaya yana da mummunan juriya na zafi da jinkirin harshen wuta, kuma yawancin samfuran bazuwar yayin konewa gas ne masu ƙonewa.Ƙara abubuwan da ke hana wuta wata hanya ce mai mahimmanci don inganta jinkirin harshen wuta na robar hydrocarbon, kuma ana amfani da tasirin haɗin gwiwar wuta don ƙara inganta tasirin wutar.Duk da haka, ya kamata a biya hankali ga mummunan sakamako na adadin wutar lantarki a kan kayan aikin injiniya na roba.
Ƙara abubuwan da za su hana wuta kamar su calcium carbonate, yumbu, foda talcum, farin carbon baƙar fata, Aluminum hydroxide, da sauransu. don rage yawan abubuwan da ake iya konewa.Calcium carbonate da nitrogen alumina suna da tasirin endothermic lokacin da bazuwar.Wannan hanya za ta rage wasu kayan aikin jiki da na inji na kayan roba, kuma adadin cikawa bai kamata ya zama babba ba.
Bugu da ƙari, ƙara yawan haɗin haɗin gwiwa na roba na iya ƙara yawan iskar oxygen.Saboda haka, zai iya inganta jinkirin harshen wuta na roba.Wannan na iya zama saboda karuwa a cikin zafin jiki na ruɓar yanayi na kayan roba.An yi amfani da wannan hanyar a cikin roba Ethylene propylene
2. roba halogenated
Rubber halogenated ya ƙunshi abubuwan halogen, tare da ma'aunin iskar oxygen gabaɗaya tsakanin 28 zuwa 45, kuma ma'aunin oxygen na FPM har ma ya zarce 65. Mafi girman abun ciki na halogen a cikin roba halogenated, mafi girman ma'aunin iskar oxygen.Wannan nau'in roba kanta yana da babban jinkirin wuta da kuma kashe kansa akan kunnawa.Saboda haka, maganin hana wuta yana da sauƙi fiye da robar hydrocarbon.Don ƙara inganta jinkirin harshen wuta na roba halogenated, ana amfani da hanyar ƙara abubuwan da ke hana wuta.
3. Heterochain roba
Mafi wakilin nau'in roba a cikin wannan nau'in shine dimethyl silicone rubber, tare da iskar oxygen na kusa da 25. Ainihin hanyoyin da za a yi amfani da harshen wuta shine don ƙara yawan zafin jiki na bazuwar zafi, ƙara yawan ragowar lokacin bazuwar thermal, da rage saurin samar da adadin kuzari. iskar gas masu ƙonewa.
