Kulanga-langa kwakusofwaazya mavalvu

1. Ino kusowa ninzi

Insimbi yamaanzi ilatilwa mumulyango wakubumba uujisi chiimo cheelede kuchibeela eecho, mpawo niyamana kuyuma, chibeela chili achiimo chimwi, bupati abubotu bwaatala chilajanwa, eecho chiitwa kuti kusofwaazya. Zintu zyotatwe zipati: kusanganya, kubamba, kutila akuyumya. Bubotu bupati: zibeela zikatazya zilakonzya kuchitwa.

2. Kusumpuka kwakusowa

Kupanga kwakatalika muma 1930 kubelesya minchina iibelesya muuya anzila zyakupanga bulongo bwamusenga.

Musyobo wasementi wakaboneka mu 1933

Mu 1944, musyobo wamusenga uujisi busani butontola wakaboneka

CO2 yakayuma maanzi gilazi lyamusenga yakazwa mu 1947

Mu 1955, chikumba chakupya chakazwa

Mu 1958, musenga uutegwa furan resin wakaboneka

Mu 1967, bulongo bwamusenga bwa sementi bwakaboneka

Mu 1968, gilazi lyamaanzi lyakajisi chintu chiyumu chakazwa

Muminyaka iili makumi musanu yainda, nzila zipya zyakupanga zibulo zyakubelesya munzila zyakumubili, zilimbuli: kubumba amagineti, nzila yakubumba kwiinda mukubelesya nzila ya vacuum sealing, kubumba kwa foomu iisweekede, azimwi. Nzila zyakupanga zisiyene-siyene ziyeeme azibulo zyabutale. Mbuli kusofwaazya kwa centrifugal, kusowa kwanguzu zyaatala, kusowa kwanguzu ziche, kusowa kwamaanzi, azimwi.

3. Zitondeezyo zyakusowa

A. Kukonzya kuchincha akukonzya kuchincha. Zyoonse zintu zipangwa abutale. Kusowa takulesyegwi abulemu, bupati abupange bwachibeela. Kulema kulakonzya kuzwa kuma gram masyoonto kusikila kumyaanda ya matani, bupati bwabwaanda bulakonzya kuzwa ku 0.3mm kusika ku 1m, mpawo chiimo chilakonzya kuba zibeela zikatazya kumvwisisisya.

B. Bunji bwazintu zitabelesyegwi azimwi zibelesyegwa zilajanwa mumasena manji alimwi taziduli pe, mbuli nsimbi zyakasyaala amusenga.

C. Kusofwaazya kulakonzya kusumpula buluzi bwakupima abwaanda bwazintu kwiinda mukubelesya nzila zyakusowa zisumpukide, kuchitila kuti zibeela zikonzye kugonkwa mbichaani kakunyina kugonkwa.
