Doorka Kaalshiyamka ee Shubka
Kaalshiyamku wuxuu u adeegaa laba shaqo oo muhiim ah oo ku jira shubka:
Biyo-yareeyaha: Kaalshiyamku wuxuu u shaqeeyaa sidii biyo-yareeye shubka. Wuxuu yareeyaa saamiga biyaha iyo sibidhka ee shubka, isagoo hagaajinaya dareere ahaan iyo awooddiisa bamgareynta. Marka la yareeyo tirada biyaha lagu daray, waxay kor u qaadaysaa xoogga iyo cimri dhererka shubka.
Retarder: Xaaladaha qaarkood ee gaarka ah, waxaa lagama maarmaan ah in la xakameeyo waqtiga dejinta shubka si loo helo dhisme wanaagsan. Kaalshiyam qaabaysan ayaa loo isticmaali karaa sidii dib-u-celin si loo yareeyo dejinta shubka, taasoo ka dhigaysa dhismaha mid aad u habboon. Gaar ahaan xilliyada heerkulka sare ama inta lagu jiro gaadiidka fog ee shubka, kaalshiyam qaabaysan ayaa si wax ku ool ah u dib u dhigaya falcelinta fuuq-celinta sibidhka, taasoo yaraynaysa kulaylka fuuq-celinta iyo xoogga da'da hore ee shubka.

Heerkulka sare ma burburinayaa awoodda shaqaynta ee shubkaaga bartamaha mashruuca? Kaalshiyamku wuxuu yareeyaa kulaylka fuuq-baxa OO wuxuu hagaajiyaa bamgareynta. Guji si aad ugala hadasho xalalka loo habeeyey!
