ZTA Alumina Ceramic Lining: Uburyo bwiza bwo kurinda umubiri budashobora kwangirika

ZTA (Zirconia Toughened Alumina) ikoze mu ibumbani ibikoresho by’ubuhanga bigezweho byakozwe binyuze mu gushyiramo icyiciro cya zirconia (ZrO₂) muri matrix ya alumina (Al₂O₃). Iyi miterere ivanze ihuza ubukana bwinshi bwa alumina n’imiterere yo gukomera ya zirconia, bityo byongera cyane ubukana bw’ibikoresho no kudahura n’ingaruka za mekanike. Imiterere yabyo isanzwe ni imwe kandi ikomeye, ifite ubucucike bwinshi muri rusange ≥3.95 g/cm³ na Rockwell hardness (HRA) ishobora kurenza 85. Ibikoresho bikorwa binyuze mu gutunganya ifu itunganyijwe, gukanda isostatic, no gushyuha cyane, bigatuma habaho ubudahangarwa bwiza mu mubiri no mu mekanike.

Ibyiza by'ingenzi by'iyi plaque biri mu kwangirika kwayo no kudashira. Mu nganda zisanzwe, igipimo cyo kwangirika kwa ZTA ceramic gishobora kuba kiri hasi ya 30%-50% ugereranyije n'iy'ibumba risanzwe rifite alumina nyinshi. Ubudashira bwayo bugira akamaro ko kwangirika gukomeye kudashira hamwe n'uburyo bwo kwinjiza ingufu z'udusimba duto duterwa no guhinduka kwa zirconia phase. Muri icyo gihe, ifite ubushobozi bwo kudashira kw'ibinyabutabire, irwanya isuri ituruka ku bintu byinshi bya aside na alkali (usibye aside hydrofluoric na alkali zikomeye zishyushye cyane). Igumana imikorere ihamye mu gihe kirekire ihura n'ubushyuhe bwinshi (ubushyuhe bwinshi bugera kuri 850°C) n'imimerere igoye yo gukora, kandi ubuzima bwayo burenze kure ubw'ibikoresho bisanzwe birinda ibyuma.

Udupira twa ZTA dukoreshwa cyane mu nganda zishaje cyane, harimo ingufu zikoreshwa n'ubushyuhe, ubucukuzi bw'amabuye y'agaciro, gukora sima, gushongesha ibyuma, no gukoresha ibikoresho. Ahantu hihariye hakoreshwa harimo ibikoresho byo gutandukanya inkubi y'umuyaga, inkokora z'imiyoboro, impellers z'abafana, chutes, hoppers, n'ibikoresho bitandukanye byo gushyira mu byiciro ifu. Uburyo bwo kuyishyiraho buratandukanye, nko gufatanya, gufunga, cyangwa gushyiramo modular, bikingira neza ibikoresho. Ibi bigabanya cyane inshuro zo kudakora no gukora ikiguzi giterwa no gusaza, bikongera imikorere myiza n'umutekano wa sisitemu.

Muri make, ZTA alumina ceramic lining yabaye ibikoresho by'ingenzi mu rwego rwo kurinda imyanda y'inganda, bitewe n'imiterere yayo igezweho mu bya siyansi n'imikorere yayo myiza cyane. Itanga icyizere cyizewe cy'imikorere irambye y'ibikoresho mu bidukikije bikomeye, itanga inyungu zikomeye mu bukungu n'agaciro k'ikoreshwa. Ubushakashatsi bukomeje mu bikoresho no kubitunganya buzarushaho kwagura imikorere yabyo n'uburyo bikoreshwa.
