1. Ni amavuta y'umunyururu w'amagare wahitamo:
Niba ufite ingengo y'imari nto, hitamo amavuta ya mineral, ariko igihe cyo kubaho cyayo ni kirekire kurusha amavuta ya synthetic. Iyo urebye ikiguzi rusange, harimo no gukumira ingese n'umunyururu, no kongeramo amasaha y'akazi, noneho kugura amavuta ya synthetic birahendutse cyane. Zigama abakozi.
Amavuta yo mu bwoko bwa synthetic ku isoko ashobora kugabanywamo ubwoko bubiri: 1. esters na 2. silikoni.
Reka tuvuge ku bwoko bwa mbere mbere: Akamaro gakomeye ka ester ni uko ifite ubushobozi bwo kwinjira neza cyane kandi ishobora kwinjira vuba mu cyuho kiri hagati y’igice cyo hagati cy’urushundura n’igice cyo ku ruhande cy’urushundura (wibuke ko urushundura rugenda bitewe no kwangirika hagati y’igice cyo hagati cy’urushundura n’igice cyo ku ruhande. Yego, icyo ukeneye amavuta ni imbere, ntabwo ari ubuso bw’urushundura. Amavuta ari hejuru ni ayo kwirinda ingese gusa. Niba ubuso bwumye kandi nta mavuta arimo, ugomba kongera gutera amavuta y’urushundura).
Reka tuvuge ku rya kabiri: Akamaro gakomeye k'amavuta ya silikoni ni uko afite ubushobozi bwo kwirinda amazi, ariko ubushobozi bwo kwinjira mu mazutu buragabanuka. Agace k'amavuta kayo biroroshye kuyamena, bigatuma adakoresha amavuta menshi kandi agasaza cyane ku mugozi. Kubwibyo, amavuta ya silikoni agira akamaro cyane iyo akoreshejwe ku buso bunyerera.
Hanyuma, muri rusange, ester zifite ingaruka nziza zo kwisiga ku migozi kandi zikwiriye cyane nk'amavuta y'imigozi kurusha amavuta ya silikoni, adakunze gufata umwanda. Zombi zifite ibyiza n'ibibi byazo, biterwa n'iryakubereye inshuti zawe.
2. Ibisabwa ku mavuta yo kohereza urunigi rw'amagare:
1: Ifite ubushobozi bwo kwinjira neza mu mubiri
2: Igomba kuba ifite uburyohe bwiza bwo gufatana
3: Imikorere myiza cyane yo gusiga amavuta
4: Gukomera cyane mu gutwika ogisijeni
5: Ifite igipimo gito cyane cyo gutakaza umwuka uva mu kirere
6: Kugira ubushobozi bwo kurwanya ingaruka zo hanze
7: Ifite imiterere yo kuba idafite umwanda
