Kodi mungasankhe bwanji zinthu zopangira zida zowotchera zinyalala?

Zowotchera moto wamba zimaphatikizapo zida zowotchera moto, zotenthetsera kabati, makina oyatsa moto a CAO, oyatsira mabedi amadzimadzi, ndi oyatsira moto oyatsira moto. Zida zopangira zida zowotchera zinyalala zili ndi izi:

StabilityGood buku bata;

OodGood kutentha mphamvu ndi kuvala kukana;

ResistanceGood acid kukana;

StabilityGood zivomerezi bata;

ResistanceGood dzimbiri kukana (NKHA, Cl2, SO2, HCl, alkali zitsulo nthunzi, etc.);

Kukhazikika kwabwino (kopanda mawonekedwe);

HeatKutentha kwabwino ndi kutchinjiriza kwa kutentha.

Zowotchera mosiyanasiyana, magawo osiyanasiyana ogwiritsira ntchito, ndi kutentha kosiyanasiyana kwa magwiridwe antchito, malingaliro otsatirawa ndi oti angotchulidwa kokha:

Kutentha kogwira ntchito padenga, pamakoma ammbali ndi chowotchera chipinda choyaka moto ndi 1000-1400 ℃, njerwa zapamwamba za alumina ndi njerwa zadothi zokhala ndi mawonekedwe a 1750-1790 ℃ atha kugwiritsidwa ntchito, ndipo mapulasitiki okhala ndi Refractoriness wa 1750-1790 ℃ amatha kugwiritsanso ntchito. ；

Mbali zakumtunda, zapakatikati, ndi zotsika za kabati zimagwiritsidwa ntchito pamoto wa 1000-1200 ° C, njerwa za silicon carbide kapena njerwa zadothi zokhala ndi mawonekedwe a 1710-1750 ° C atha kugwiritsidwa ntchito, komanso zida zosavala kugwiritsidwa ntchito;

Kutentha kwantchito padenga ndi pamakoma am’mbali mwa chipinda chachiwiri choyaka moto ndi 800-1000 ℃, ndipo njerwa zadongo kapena zida zadothi zokhala ndi zotsika zotsika kuposa 1750 ℃ ​​zitha kugwiritsidwa ntchito;

Khoma lakumtunda ndi kumtunda kwa chipinda chosinthira kutentha, ndipo pamwamba, pamakoma ammbali, ndi pansi pa chipinda chopopera chimagwiritsidwa ntchito pamlingo wotsika kuposa 600 ° C. Njerwa zadothi kapena zomata zadothi zokhala ndi mawonekedwe obwezeretsa pansi kuposa 1710 ° C zitha kugwiritsidwa ntchito;

Sinthani kutentha kwa flue ndi flue mpaka 600 ° C, ndikusankha njerwa zadothi kapena zomata zadothi zosanja poyerekeza ndi 1670 ° C.

Kusankhidwa kwa zida zotsukira kwa omwe ali pamwambapa kuyenera kutengera zochitika zina. Mitundu yosayatsa moto iyenera kutsimikizika ndi mikhalidwe yovuta kwambiri pazida za zida kuphatikiza zinthu zosiyanasiyana.
