Zifukwa zomwe zimakhudza kutentha kwa rabara

Kuwotcha kwa mphira ndi mtundu wa khalidwe lapamwamba la vulcanization, lomwe limatanthawuza zochitika za vulcanization yoyambirira yomwe imapezeka m'njira zosiyanasiyana isanayambe vulcanization (kuyenga mphira, kusungirako mphira, extrusion, rolling, kupanga). Choncho, akhoza kutchedwanso oyambirira vulcanization. Kuwotcha kwa mphira ndi mtundu wa khalidwe lapamwamba la vulcanization, lomwe limatanthawuza zochitika za vulcanization yoyambirira yomwe imapezeka m'njira zosiyanasiyana isanayambe vulcanization (kuyenga mphira, kusungirako mphira, extrusion, rolling, kupanga). Choncho, akhoza kutchedwanso oyambirira vulcanization.

Zifukwa za zochitika zowotcha:

(1) Kapangidwe ka fomula kolakwika, kusalinganiza kachitidwe ka vulcanization kosagwirizana, komanso kugwiritsa ntchito mopitilira muyeso wa ma vulcanizing agents ndi ma accelerator.

(2) Kwa mitundu ina ya mphira yomwe imayenera kusungunuka, pulasitiki sichigwirizana ndi zofunikira, pulasitiki ndi yotsika kwambiri, ndipo utomoni ndi wovuta kwambiri, zomwe zimapangitsa kutentha kwakukulu panthawi yophatikiza. Ngati kutentha kwa makina oyenga mphira kapena zipangizo zina zodzigudubuza (monga mphero ndi mphero) ndizokwera kwambiri ndipo kuzizira sikukwanira, kungayambitsenso kuphika pa malo.

(3) Potsitsa mphira wosakanizidwa, zidutswazo zimakhala zolemera kwambiri, kutentha kwa kutentha kumakhala kosauka, kapena kumasungidwa mofulumira popanda kuzizira. Kuonjezera apo, mpweya woipa komanso kutentha kwakukulu m'nyumba yosungiramo katundu kungayambitse kutentha, zomwe zingayambitsenso kuphika.

(4) Kusamalidwa bwino pa nthawi yosungiramo zinthu za rabara kunachititsa kuti pakhale kutentha kwachilengedwe ngakhale nthawi yotsalayo itatha.

Zowopsa za kutentha:

Kuvuta pokonza; Zimakhudza thupi katundu ndi pamwamba kusalala kwa mankhwala; Zitha kupangitsanso kutha kwa kulumikizana kwazinthu ndi zochitika zina.

Njira zopewera kuyaka:

(1) Mapangidwe a zinthu za mphira ayenera kukhala oyenera komanso omveka, monga kugwiritsa ntchito njira zingapo za accelerator momwe zingathere. Kuchepetsa kutentha. Kuti mugwirizane ndi kutentha kwakukulu, kuthamanga kwambiri, ndi njira zoyeretsera mphira wothamanga kwambiri, kuchuluka koyenera (magawo 0.3-0.5) a anti coking agent akhoza kuwonjezeredwa ku formula.

(2) Limbikitsani njira zoziziritsira zida za mphira pakuyenga mphira ndi njira zotsatila, makamaka poyang'anira kutentha kwa makina, kutentha kwa wodzigudubuza, ndikuwonetsetsa kufalikira kwamadzi ozizira kokwanira, kuti kutentha kwa ntchito sikudutsa nsonga yofunika kwambiri yophika.

(3) Samalirani kasamalidwe ka zida za mphira zomwe zatha, ndipo gulu lililonse lazinthu liyenera kutsagana ndi khadi loyenda. Gwiritsani ntchito "choyamba, choyamba" chosungirako, ndipo tchulani nthawi yosungiramo galimoto iliyonse ya zipangizo, zomwe siziyenera kupyola. Malo osungiramo zinthu ayenera kukhala ndi mpweya wabwino.
