Acid kūpaʻa castable ua kapaia refractory castable, o ia kekahi o ka refractory mea, a hiki ke pale aku i ka waika erosion, i hoʻohana nui 'ia i loko o non-ferrous metallurgy, kemika 'oihana, chimney, etc. ʻoi aku ka kiʻekiʻe o ka castable o ka mea hoʻopaʻa paʻa a me ka wai a me ka wai nui. ʻO ka refractory ʻaʻole i hoʻoheheʻe ʻia he ākea ākea o ka noi a hiki ke hoʻohana ʻia ma o ka ninini ʻana a i ʻole ramming e like me ke koho ʻana o nā kūlana lawelawe no nā mea a me nā mea paʻa.
Acid resistant castable manufacturing kaʻina mea maʻalahi me ka kūikawā lako. Acid resistant castable he kiʻekiʻe mechanical ikaika a kiʻekiʻe kiʻekiʻe. He maʻalahi ke kūkulu ʻana ma ke ʻano o ka ninini ʻana. Hiki ke hoʻohana pololei ʻia nā castables kūpaʻa i ka wai i loko o ka ʻenekinia me ke kī ʻole. A hiki i ka waika pale refractory castable ke pale aku i ka waika medium corrosion o 800 ~ 1200 ℃ hiki ke ninini ʻia i kapa ʻia ʻo refractory acid resistant castable. Hana ʻia ʻo Refractory acid resistant castable me ke aniani wai e like me ka binder, acid or alkali acid refractory e like me ka aggregate a me ka pauka, a me kahi liʻiliʻi o ka coagulant. Eia nō naʻe, ʻaʻole kūpaʻa kēlā mau hoʻoheheʻe ʻana i ka corrosion e ka alkali, hydrochloric acid, hydrofluoric acid a me ka momona kiʻekiʻe.
ʻO ka hui maʻamau o ka hoʻoheheʻe ʻana i ka waika: acid-resistant refractory aggregate (60-70%), pauka (30-40%), a me ka sodium fluorosilicate (13% -16%) ma ke ʻano he mea paʻakikī.

Acid resistant castable ua hoʻohana nui ʻia i ka mea kanu petrochemical acid a me ka mea kanu sulfuric acid.
Hiki ke hoʻolei ʻia ka mea hoʻoheheʻe refractory kūpaʻa i ka wai i loko o ka uhi o ke kino a hiki ke hana ʻia i nā huahana precast. ka mea i hoʻohana nui ʻia no nā linings o nā kapuahi like ʻole a me nā kilns, a ua hoʻohana nui ʻia ka castable kūpaʻa waikawa i ka umu ahi o ka ʻoihana metallurgical, ʻoihana ʻaila, ʻoihana kemika, nā mea kūkulu hale a me nā ʻoihana ʻenekinia no ka pale ʻana i ka wela wela.
ʻO ka hale hana refractory RS he mea hoʻolako hoʻolako hoʻokele waiwai i hoʻokumu ʻia i ka makahiki 90 o iwakālua mau kenekulia. ʻO ka hale hana refractory RS he loea i nā castables kūpaʻa wai no nā makahiki he 20. inā loaʻa iā ʻoe kekahi koi o ka refractory acid resistant castable, a i ʻole he mau nīnau e pili ana i ka acid resistant refractory castable e pili ana i nā hōʻailona kino a me nā kemika, e ʻoluʻolu e kelepona mai iā mākou no ka manuahi. a me ka hale hana refractory Rs ma ke ʻano he mea hana castable kūpaʻa waika ʻoihana ma Kina, he mau pono hoʻokūkū e like me kēia:
