M'zaka zaposachedwa, ndikupita patsogolo kwaukadaulo wamigodi yamalasha, njira yachitukuko chonyamula lamba wapansi popita patali, kulumikizana kwakukulu, ngodya yayikulu ndikuthamanga kwambiri kukuwonekera kwambiri, motero kupititsa patsogolo chitukuko cha khalidweli lamba wofiyira woyendetsa. Zofunikira zatsopano zimapangidwanso kutsogolo kwa ukadaulo ndi zida zamagetsi opanga lamba wapa.

M'tsogolomo, woperekera katunduyo adzafika pamlingo wokulirapo (kutulutsa mphamvu zazikulu, kutalika kwa makina amodzi ndi kupendekera kwakukulu, etc.), kukulitsa kukula kwa ntchito, kuchepetsa mphamvu zamagetsi, kuchepetsa kuipitsa ndi zina zotero.

Lamba lonyamula likupita kukuwongolera mayendedwe osiyanasiyana, ambiri opanga, opepuka, opanga ntchito zambiri, opulumutsa mphamvu, chitetezo, chitetezo cha chilengedwe ndi moyo wautali.

Pakati pawo, lamba wokhazikitsidwa-ndi cholinga chopangira lamba amatengera mbali yayikulu ndikukhala kocheperako, ndipo chingwe cholumikizira chitsulo chimalipira chidwi chakuwongolera magwiridwe antchito a anti-effect, anti-misodzi, kuvala kukana ndi zina zotero.

Pakadali pano, mulingo woyendetsera lamba wopitilira womwe maiko otukuka afika pa 4000mm, m'lifupi mwa lamba wotulutsa ungathe kufika pa 6400mm, mphamvu ya lamba wonyamula katundu imatha kupitirira 8000N / mm, moyo wautumiki wa nsalu chapakati lamba nthawi zambiri amakhala wazaka zisanu ndi zitatu, ndipo lamba wachitsulo wazitsulo wazitsulo wakhala zaka zoposa 20.

Pakupita zaka zoposa 50 za chitukuko, makampani ogulitsa lamba akhala dziko lalikulu pakupanga lamba ndi zakumwa padziko lonse lapansi, chifukwa pafupifupi 1/3 ya mowa womangidwa padziko lonse lapansi. malonda ali ndi zambiri zaluso, zomwe zimathandiza kupulumutsa zinthu komanso kuteteza chilengedwe.

Mitundu yosiyanasiyana iyi ikugwirizana ndi miyezo yapadziko lonse lapansi, ndipo miyezo yapadziko lonse lapansi GB / T7984-2001 ndi GB / T9770-2001 yomwe ikuchitika mdziko lathu kwenikweni ikugwirizana ndi miyezo yapadziko lonse lapansi, ndipo lamba wonyamula ndi ulusi wopanga ndi waya waya wachitsulo monga mafupa adawerengera 80% ya zotuluka za lamba wonyamula katundu, kufikira gawo lapamwamba lapadziko lonse.

M'zaka zaposachedwapa, zitsulo waya pakati lawi-wamtundu wonyamula lamba kwa mgodi mobisa malasha anayamba malinga ndi muyezo MT668 ndi kutentha zosagwira kalasi ukufika 250Mel 300.

Lamba wonyamula wotentha wa C ali pamalo otsogola padziko lapansi.
