Banda wasu kayayyakin roba na roba da aka yi da roba, yawancin kayayyakin roba na roba, kamar roba ta halitta, kayan wuta ne masu iya ƙonewa ko kuma masu ƙonewa. A halin yanzu, manyan hanyoyin da ake amfani da su don inganta rage ƙonewa sune ƙara masu rage ƙonewa ko abubuwan cikawa masu rage ƙonewa, da kuma haɗawa da gyara su da kayan hana ƙonewa. Akwai nau'ikan fasahohin hana ƙonewa da dama don roba:
1. Roba mai amfani da iskar carbon
Robar Hydrocarbon ta ƙunshi NR, SBR, BR, da sauransu. Robar Hydrocarbon gabaɗaya ba ta da juriya ga zafi da kuma hana harshen wuta, kuma yawancin kayayyakin ruɓewa yayin ƙonewa iskar gas ce mai ƙonewa. Ƙara masu hana harshen wuta hanya ce mai mahimmanci don inganta hana harshen wuta na robar hydrocarbon, kuma ana amfani da tasirin haɗin gwiwa na masu hana harshen wuta don ƙara inganta tasirin hana harshen wuta. Duk da haka, ya kamata a kula da mummunan tasirin da adadin masu hana harshen wuta ke yi wa halayen injina na roba.
Ƙara abubuwan cikawa marasa amfani kamar calcium carbonate, yumbu, foda talcum, farin carbon black, aluminum hydroxide, da sauransu don rage yawan abubuwan da ke ƙonewa. Calcium carbonate da nitrogen alumina suna da tasirin endothermic lokacin da suka ruɓe. Wannan hanyar za ta rage wasu halaye na zahiri da na inji na kayan roba, kuma bai kamata adadin cikewar ya yi yawa ba.
Bugu da ƙari, ƙara yawan haɗin roba na iya ƙara yawan iskar oxygen. Saboda haka, yana iya inganta jinkirin harshen wuta na roba. Wannan yana iya faruwa ne saboda ƙaruwar zafin ruɓewar zafi na kayan roba. An yi amfani da wannan hanyar a cikin robar Ethylene propylene
2. Roba mai haske
Robar da aka yi da halogen ta ƙunshi abubuwan halogen, tare da ma'aunin iskar oxygen gabaɗaya tsakanin 28 da 45, kuma ma'aunin iskar oxygen na FPM ma ya wuce 65. Mafi girman abun ciki na halogen a cikin robar da aka yi da halogen, mafi girman ma'aunin iskar oxygen. Wannan nau'in robar da kanta tana da babban jinkirin wuta da kuma kashe kanta lokacin kunna wuta. Saboda haka, maganin hana wuta ya fi sauƙi fiye da robar hydrocarbon. Don ƙara inganta jinkirin wuta na robar da aka yi da halogen, yawanci ana amfani da hanyar ƙara hana wuta.
3. Roba mai sarka
Nau'in roba mafi wakilci a wannan rukunin shine robar silikon dimethyl, tare da ma'aunin iskar oxygen na kusan 25. Hanyoyin da ake amfani da su na hana harshen wuta sune don ƙara zafin ruɓewar zafi, ƙara ragowar yayin ruɓewar zafi, da kuma rage yawan samar da iskar gas mai ƙonewa.
