Opanga ndi ogulitsa opaka utoto woteteza moto ku China

Chophimba choyaka moto chosagwira moto

Chophimba choteteza moto cha intumescent Chithunzi Chowonetsedwa

kufotokozera mwachidule:

Kukulitsa chophimba chosapsa ndi moto ndi ntchito yapadera. Chimatha kumamatira pamwamba pa substrate ngati chophimba wamba kutentha kwa chipinda. Komabe, chikayikidwa pa kutentha kwakukulu kapena malawi, chimakula mofulumira ndikukhala kaboni, ndikupanga gawo lokhuthala, loteteza kutentha, motero chimateteza substrate yamkati ndikupereka nthawi yamtengo wapatali yothawira ndi kupulumutsa.

KUGWIRA NTCHITO KWA ZOKHUDZA ZOSAGWIRA NTCHITO ZOSAPANDA KUTENTHA KWAMBIRI KULI M'Mbali IZI:

Imakula ikakumana ndi moto, ndikupanga gawo lothandiza loteteza kutentha: Iyi ndiye ntchito yake yayikulu. Pamene chophimbacho chikayaka moto, zinthu zoletsa moto zamkati ndi zinthu zotulutsa thovu zimayankha mwachangu, zomwe zimapangitsa kuti kuchuluka kwake kukulire ndi nthawi 5 mpaka 20 kapena kuposerapo; mwachitsanzo, chinthu china chimatha kukula nthawi 20 pamene chili ndi makulidwe a 0.6mm chikayaka moto, ndikupanga gawo lolimba la carbonized kapena gawo la ceramic. Gawo lokulitsali limatha kulekanitsa kutentha ndi mpweya bwino, kuchepetsa kukwera kwa kutentha kwa substrate. Kukana kutentha kwambiri komanso kutetezera kutentha: Zophimba zapamwamba kwambiri zimatha kupirira kutentha kwambiri kwa moto. Mwachitsanzo, chinthu china chimatha kusunga kutentha kumbuyo kusapitirire 200℃ mkati mwa mphindi 5 chikayaka moto wa 1000℃; kafukufuku wina akuwonetsa kuti pa lawi la 850℃ kwa mphindi 15, kutentha kwa pamwamba pa kuzizira ndi 122.3℃ yokha. Zophimba zina zapadera zimatha kukhala ndi malire oletsa kutentha mpaka 2000℃. Kapangidwe kake kokhala ndi mabowo kapena vacuum komwe kamapangidwa pambuyo pokulitsa kumakhala ndi kutentha kochepa kwambiri (monga mpaka 0.022W/mK), zomwe zimapangitsa kuti kutentha kukhale kotentha kwambiri.

Mphamvu yabwino kwambiri yoteteza substrate

Mwa kuchedwetsa kusamutsa kutentha kudzera mu chotenthetsera, zimatha kuteteza bwino zinthu monga zitsulo, kusunga mphamvu zake ngakhale kutentha kwambiri. Pomanga zitsulo, izi zitha kupereka maola 1-3 kapena nthawi yayitali yotetezera anthu kuti asamuke komanso kupulumutsa ozimitsa moto.

Makhalidwe abwino a thupi ndi mankhwala: Zophimba zamakono zokulira sizimangolimbana ndi moto komanso zimakhala ndi mphamvu yolimba kwambiri (zina zimatha kufika pamlingo wa 0), kukana dzimbiri ndi asidi, kukana nyengo, komanso kukana kukhudzidwa. Zinthu zina zimagwiritsa ntchito njira zopanda zosungunulira kapena zochokera ku madzi, zomwe zimakhala zoteteza chilengedwe komanso zopanda poizoni, zomwe zimakwaniritsa zofunikira zamakono zoteteza chilengedwe.
