Zitsulo zolimbitsa utsi ndi gulu lapadera la zipangizo zachitsulo zomwe zakhala zofunikira kwambiri m'mafakitale a magalimoto ndi zipangizo zamagetsi. Mphamvu yawo yapadera yowonjezera mphamvu panthawi yopangira utoto imapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito komwe kumafunika kupangika bwino komanso mphamvu yomaliza. Kumvetsetsa tanthauzo la zitsulo zolimbitsa utsi, njira zomwe amapangira, ndi momwe amagwiritsidwira ntchito kungathandize ogula ndi mainjiniya kupanga zisankho zodziwa bwino akamagula zitsulo zapamwamba. M'nkhaniyi, tifufuza tanthauzo la zitsulo zolimbitsa utsi, ubwino wake, kapangidwe ka mankhwala, ntchito, ndi zomwe zikuchitika mtsogolo.

Tanthauzo la Zitsulo Zouma Zophikira

Zitsulo zouma zophikira, zomwe nthawi zambiri zimafupikitsidwa kuti zitsulo za BH, ndi zitsulo zopanda mpweya wambiri zomwe zimapeza mphamvu yowonjezera yobereka pambuyo poti zapangidwa kenako n’kupakidwa utoto pa kutentha kwa pafupifupi 170–200°C. Kulimbitsa kumeneku kumachitika chifukwa cha kuyanjana pakati pa maatomu a kaboni kapena nayitrogeni komanso kusokonekera komwe kumachitika panthawi yopanga. Kuthekera kopeza mphamvu yowonjezera panthawi yophika kumapangitsa kuti zitsulozi zikhale zofunika kwambiri m'mafakitale komwe kuchepetsa kulemera ndi kukonza mphamvu ndikofunikira.

Njira Yofunika Kwambiri Yophikira Kuphika

Njira yaikulu yomwe imagwiritsa ntchito zitsulo zouma zophikira imadziwika kuti ndi kukalamba kwa strain. Pamene chitsulocho chasokonekera panthawi yopangidwa, kusuntha kumalowetsedwa mu kapangidwe ka kristalo. Panthawi yophika utoto, maatomu a kaboni ndi nayitrogeni amafalikira ndikutseka kusunthaku, motero amawonjezera mphamvu ya chitsulocho. Njirayi imalola chitsulocho kukhalabe ndi mawonekedwe abwino kwambiri panthawi yopanga pomwe chikupeza mphamvu zambiri pakugwiritsa ntchito kwake komaliza.

Kapangidwe ka Mankhwala a Zitsulo Zouma Zophikira

Zitsulo zouma zophikira nthawi zambiri zimakhala zitsulo zopanda mpweya wambiri zomwe zimakhala ndi zinthu zosungunuka bwino.
