Kugawika kwa insulation refractories

Ngati agawidwa malinga ndi kutentha ntchito, kutentha kutchinjiriza zipangizo refractory akhoza kugawidwa m’magulu atatu:

① Low-kutentha kutchinjiriza zipangizo, otsika kuposa 600 ℃;

②Sing’anga kutentha kutchinjiriza zakuthupi, 600 ~ 1200 ℃;

③ High kutentha kutchinjiriza zakuthupi, apamwamba kuposa 1200 ℃.

Malinga ndi kachulukidwe kachulukidwe, kachulukidwe wochulukira wa zinthu zopepuka zotsekereza zotchingira kutentha nthawi zambiri saposa 1.3g/cm3, ndipo kachulukidwe kazinthu zomwe zimagwiritsidwa ntchito mopepuka zoteteza kutentha ndi 0.6~1.0g/cm3, ngati kachulukidwe kake ndi 0.3 ~ 0.4 g / cm3 kapena kutsika, amatchedwa ultra-lightweight insulation material.

Insulating refractory zipangizo angathenso kugawidwa mu:

①Zida zotsekereza ufa ndi granular zimaphatikizanso zinthu zambiri za ufa-tirigu zomwe zimagwiritsa ntchito ufa wonyezimira kapena zinthu zong’ambika ngati kudzaza zosanjikiza zomangira, ndi zida za ufa wochuluka wopepuka wopepuka wopepuka wa amorphous kutentha-zoteteza zinthu zomwe zimakhala ndi cholumikizira. Powdey granular thermal insulation material ndiyosavuta kugwiritsa ntchito komanso yosavuta kupanga. Itha kutchedwa wosanjikiza wotenthetsera wamatenthedwe wamakina otentha kwambiri ndi zida podzaza ndi kupanga pamalowo.

②Zida zokongoletsedwa zotsekereza kutentha zimatanthawuza zida zotchingira kutentha zokhala ndi mawonekedwe enaake okhala ndi porous. Zina mwa izo, zopangidwa ndi njerwa ndizofala kwambiri, choncho nthawi zambiri zimatchedwa njerwa zotetezera kutentha. Njerwa zonyezimira zopepuka zimadziwika ndi magwiridwe antchito okhazikika, ndipo ndizosavuta kugwiritsa ntchito, zonyamula ndi zosungira.

③ Zida zotchingira kutentha kwa ulusi zimakhala ngati thonje komanso zotchinga ngati fiber. Zida za fibrous ndizosavuta kupanga mapangidwe a porous. Chifukwa chake, zida zotchinjiriza za fibrous zimadziwika ndi kulemera kopepuka, magwiridwe antchito abwino amatenthedwe, kukhazikika, komanso kuyamwa kwamawu komanso kukana kugwedezeka.

④Zida zotchinjiriza zophatikizika zimatanthawuza za zida zotchinjiriza zomwe zimapangidwa ndi fiber ndi zinthu zina, monga mapanelo otsekera, zokutira ndi zida zina zotchinjiriza.

Mawonekedwe ndi mawonekedwe ogawa agawidwa m’magulu atatu awa:

①Zida zotsekemera zomwe gawo la gasi ndi gawo lopitilira ndipo gawo lolimba ndilo gawo lobalalika;

②Zida zoziziritsa kukhosi zomwe gawo lolimba ndi gawo lopitilira ndipo gawo la gasi ndi gawo lobalalika;

③Zida zodziyimira pawokha momwe gawo la gasi ndi gawo lolimba ndi magawo opitilira. Njira yamagulu awa ndiyosavuta kusanthula ndikuphunzira momwe gulu limakhudzira magwiridwe antchito azinthu zotenthetsera kutentha.
