Menene yumbun da ake amfani da su don faranti masu hana harsashi?
Abubuwan yumbu a cikin faranti masu hana harsashi gabaɗaya suna amfani da abubuwa daban-daban guda uku masu zuwa:
1. Alumina yumbura
Abubuwan yumbu na alumina suna da mafi girman yawa a cikin kayan uku.A ƙarƙashin wannan yanki, faranti masu hana harsashi da aka yi da yumbun alumina sun fi nauyi.Amma farashin yumburan alumina yana da ƙasa sosai.Saboda haka, wasu abokan ciniki waɗanda ke buƙatar sayayya masu girma za su zaɓi wannan faranti mai hana harsashi.
2. Silicon carbide yumbura
Farashinsa yana da tsada sosai, sau 4 zuwa 5 na yumbu alumina, amma nauyi mai nauyi zai iya kawo ƙwarewar sawa mafi kyau kuma ya rage yawan ƙarfin jiki.Idan abokin ciniki ne wanda ke da isassun kuɗi bayan haka, ana ba da shawarar zaɓin irin wannan faranti na harsashi.
3. Boron carbide yumbu
Farashin boron carbide yana da tsada sosai, wanda zai iya kaiwa sau 8 zuwa 10 na silicon carbide.Saboda girman darajar sa, gabaɗaya muna amfani da wannan kayan ne kawai a cikin faranti na NIJ IV.
