1. Okufuula omupiira mu ngeri ey’ekibogwe .
Goodyear, omuyiiya w’Amerika omwavu, yali mumalirivu okukyusa omupiira omubisi okufuuka ekintu ekirungi ennyo ekyali kigonvu era nga kikaluba. Yakwatibwako nnyo omupiira okumala emyaka egisukka mu 30, naye obulamu bwe yabumala mu bwavu. emboozi mu kibuga Goodyear: Oyagala okufuna Goodyear? Laba, awo we kiri! He wore a rubber cap, a rubber lined windbreaker, a rubber vest underneath and rubber pants underneath. Rubber boots and a rubber purse-not a cent in it. Goodyear gels were mixed with magnesium oxide, boiled in lime water, boiled in nitric acid, sprinkled with sulfur on the surface of gels, dried in the sun, and so on. After all his experiments Yali alemereddwa, yateeka ebitundutundu bya ggaamu omubisi, ekibiriiti eky’obuwunga, ne turpentine mu kibya n’akifumba ku sitoovu. mu butanwa, ekitundu kya kalaamu ekyafuluma mu kiyungu n’agwa mu muliro, ng’ayokya naye nga takwata. nga ye yabuuka olunaku lwonna{{9} kapiira, yasimbiddwa n’ekibiriiti, yali alinda olunaku lwonna{{10} 2} 2}
In today's rubber factories, this is called the vulcanization process. Since then, raw rubber has been transformed into a useful material. Goodyear's vulcanization process was later figured out by chemists: sulfur atoms built "Bridges" between large molecular chains of raw rubber, as if the springs of a sofa were connected to each other with twine and wire, elastic but not loose.
2. Dose etya omuddugavu n’enjeru eya kapiira ekyuka?
Omupiira ogutabuddwa ne kaboni omuddugavu guyinza okukaluba era ne gugumira okwambala. sole, langi enjeru ey’omupiira gwa kapiira eva ku kaboni omuddugavu. omupiira omweru ogutaliiko kaboni omuddugavu, ssaako kaboni enjeru enjeru kaboni, Qin White Powder Filler. Eraser pencil ebigambo bisobola okukolebwa mu kapiira omweru yekka, tebisobola kusangula kkalaamu ebigambo naye left a black mark {3} kale nga njeru ne kiddugavu 4 nga kiddugala kya random ku pencil ebigambo naye left a black mark {3} kale nga muddugavu ne kiddugala ne kiddugala nga kiddugavu 4} nga kiddugala 4} nga kiddugavu 4} nga kiddugavu 4} nga kiddugala 4} nga kiddugala nga kiddugala 4} nga kiddugavu 4} nga kiddugala nga kiddugavu 4, nga tekisobola kulonda kkalaamu ya pencil naye nga kirekeddwa mu pencil 1. of society, ensangi zino, okugattako fillers mu kapiira kiyinza okufuula ebintu okulabika nga langi ez’enjawulo, ezisobola okutuukiriza ebyetaago by’abantu ab’omulembe guno olw’ebintu bya kapiira.
