Mphamvu, kuvala kukana ndi kukana kwaNjanji njanji zogulitsaZimatengera kuchuluka kwa njanji, ndiye kuti, pa kapangidwe ka mankhwala, gulu lachitsulo, bungwe la kupanga ndi kutentha kwa chitsulo. Kuphatikizika kwa njanji, kuphatikizaponso chitsulo, kuphatikizaponso kaboni, manganese, silicon, sulufule ndi phosphorous. Zolemba za carbon zimatha kuwonjezera mphamvu ya njanji, koma zochulukirapo za carbon zimachepetsa pulasitiki yake. Kuchulukitsa zomwe zango ndi silika kumatha kuwonjezera mphamvu, kuuma ndi unyinji wa njanji. Sulfur ndi phosphorous ndi zonyansa zovulaza ndipo siziloledwa kupitilira malire. Kuphatikiza apo, kuwonjezera kuchuluka koyenera kwa chromium, nickel, molybdenum, vadium, titanium kapena mkuwa kumtengowo kuti apangitse njanji. Kuyambira m'ma 1970, China chatulutsa njanji zotsika kwambiri padziko lapansi, manganese ochepa, silicon, titanium ndi mkuwa. Pofuna kusintha mphamvu ya anti-kuvala njanji yotsiriza, pewani kuphwanya yunifolomu, gwiritsani ntchito yunifolomu nthawi zambiri nthawi zambiri kumachitika mbali zonse ziwiri za njanji kuti zitheke kuvuta kwake; Kutalika kwathunthu, njanji yabwino Gwiritsani ntchito mphamvu.
Njira Zopangira Zogulitsa
Tekinoloje ndi njira zomangira
Njira yopangaSitima yapamtundaMaulendo amafunika kukhala ogwiritsa ntchito bwino komanso kuganizira zinthu zosiyanasiyana mosamala. Zimayamba ndikupanga njirayi, poganizira zomwe mukufuna, ma Stimaet, ndi malo. Kapangidwe kameneka kamamalizidwa, njira yomanga ikuyamba ndi njira zotsatirazi:
1. Kukula ndi Maziko: Gulu lomanga limakonzekereratu malowa ndikupanga maziko olimba kuti athandizire kulemera ndi kupsinjika komwe kumakhazikitsidwa ndi sitimayo.
2. Kukhazikitsa Ballast: wosanjikiza mwala wosweka, yemwe amadziwika kuti ndi wowoneka bwino. Izi ndizosangalatsa pang'ono, kusangalatsa, komanso kuthandiza kugawa katunduyo.
3. Maumboni ndi Omangirira: Matabwa kapena matabwa kapena konkriti amaikidwa pamwamba pa ballast, kutsanzira mawonekedwe ngati mawonekedwe. Mautuwa amapereka maziko otetezeka a njanji zachitsulo. Amakhala okhazikika pogwiritsa ntchito spikes kapena ma clips, ndikuwonetsetsa kuti angokhala malo.
4. Kukhazikitsa njanji: Makatani a njanji ya njanji 10m, nthawi zambiri amatchedwa Ngabali zokhazikika, zimayikidwa bwino pamwamba pa maudindo. Kupangidwa ndi chitsulo chowoneka bwino kwambiri, ma njati awa amakhala ndi mphamvu komanso kulimba.
