Iyo abantu bavuga kubyerekeye ibishashara byatakaye, akenshi baba bashishikajwe no gushushanya ibishashara cyangwa icyuma gisuka. Ceramic slurry? Ifatwa nkirangi ryoroshye, intambwe yinyuma. Iri ni ikosa rya mbere. Mubyukuri, gusebanya nuburyo busanzwe bukora ibumba; imyitwarire yacyo itegeka niba ubona casting itagira inenge cyangwa ikirundo gihenze. Ntabwo ari ibicuruzwa. Icyiciro gikora ibyuma bidafite ingese birashobora kunanirwa bikabije kubintu bikikijwe na nikel ishingiye ku mavuta. Nabonye amaduka menshi cyane, niyo yaba inararibonye, abifata nkubunini bumwe-buvanze, gusa mpura nibisasu byacitse, ibishyizwemo, cyangwa birangiye biteye ubwoba, hanyuma nkagaya dewaxing cyangwa itanura. Ubusanzwe ukuri gutangirira kuri tank.
Birarenze Ibyondo gusa - Ibigize ni Umushyikirano
Urufatiro rworoshye: ifu yangiritse (nka silika yahujwe na zircon) hamwe na binder, mubisanzwe silika ya siloidal cyangwa silike ya Ethyl. Ariko ibintu byoroshye birangirira aho. Ingano yubunini bwo gukwirakwiza ifu irakomeye. Ukeneye kuvanga ibinyampeke nimbuto nziza kugirango ugere kubwinshi bwo gupakira. Nibyiza cyane, kandi uzabona kugabanuka gukabije no gucika mugihe cyo kumisha no kurasa. Birakabije, kandi ubuso bwawe burangiye buzaba bubi, gutakaza ibisobanuro byose wakoze cyane kugirango ufate mumashashara. Kubenshi mubikorwa byacu hamwe ceramic slurry yo guta ibishashara kuri QSY, twegamiye kuri sisitemu ya zircon kubushyuhe bwo hejuru. Ifite retratifike yo hejuru, idashobora kuganirwaho mugihe urimo gusuka amavuta ya cobalt asakuza avuza itanura.
Guhitamo guhuza nubundi guhamagarwa. Siloidal silika ikoreshwa nabakoresha, ishingiye kumazi, ariko yubaka imbaraga buhoro. Ethyl silikatike yubaka igikonjo gikomeye cyane, ariko ishingiye ku nzoga - ibyago byo kuzimya umuriro, kugenzura ububobere buke, kandi birashobora gutuma igikonoshwa gikomera, bigatuma amarira ashyushye mucyuma. Dukoresha byombi, ariko kubintu bigoye, byoroshye-ibice byibyuma cyangwa bidafite ingese, akenshi tujyana na sisitemu ya Hybrid. Nukuringaniza imbaraga zicyatsi, imbaraga zashizwemo, hamwe na permeability. Nta gisubizo cy'igitabo; ni resept uhindura ukurikije ubuhehere buri mumahugurwa uwo munsi.
Noneho hariho inyongera. Ibitonyanga bike byumuti wo kugabanya kugabanya ubukana bwubuso bityo ibishishwa bitwikiriye ibishashara bingana, cyane cyane hejuru ya hydrophobique. Defoamer ni itegeko-umuyaga mwinshi wafashwe nudusimba dutegereje kubaho. Rimwe na rimwe, ijanisha rito ryinyongera rirwanya anti-veining rirakenewe kuri geometrike zimwe na zimwe kugirango wirinde ubwoya bwimisatsi muri ceramic. Uravanga ibi, kandi ntubireba gusa; urabyumva. Ubukonje bugomba gutwikira urutoki muburyo bwihariye, hasigara urwego, rutagaragara. Turabigenzura hamwe nigikombe cya Zahn, ariko abasore babimenyereye bazi uburyo gitonyanga.
Diyabule ari mubikorwa: Rheologiya no kugenzura
Kuvanga ntabwo ari uguta ibintu muri tank gusa. Nibigenzurwa, akenshi bitinda, inzira kugirango wirinde gukubita umwuka mubi. Dukoresha icyuma kivanga gifite inguni yihariye. Nyuma yo kuvanga, ibishishwa bigomba gusaza-rimwe na rimwe amasaha 24-kugirango chimie ihagarare. Imvugo yayo irahinduka. Igishishwa gishya gishobora kuvamo vuba vuba mugiti cyashashara, hasigara ikote rito, ridakomeye. Umuntu ugeze mu za bukuru azaba afite umutungo mwiza wa thixotropique: itemba iyo ihagaritse umutima ariko igakomeza imiterere yayo mugihe ikiri, yubaka urwego rumwe.
Kugenzura ibipimo ni imihango ya buri munsi. Ubucucike (cyangwa uburemere bwihariye) bugenzurwa mu rwego rw'idini. Amazi amaze guhinduka, ubucucike burazamuka, kandi ugomba kubuhindura ukoresheje amazi yatoboye. Viscosity irasuzumwa mbere ya buri mwanya. pH ibibazo bya sisitemu ya siloidal silika; niba igenda, ibice bya silika birashobora gutangira kuza igihe kitaragera, byangiza icyiciro cyose. Nabuze ikigega cya litiro 500 inshuro imwe kuko indobo yanduye yakoreshejwe, ihindura pH. Iri ryari isomo rihenze muri disipulini ikurikirana. Ntabwo urimo kubungabunga amazi gusa; urimo kubungabunga sisitemu nzima.
Kwibiza inteko zishashara nubuhanzi. Ikoti rya mbere, cyangwa ikote ryambere, ni ngombwa cyane. Irasobanura ubuso burangiye. Dukunze gukoresha ifu nziza hano, rimwe na rimwe ndetse tukongeraho na zircon nziza. Igihe cyo kumena, kuzenguruka igiti kugirango wirinde guhuriza hamwe, kugenzura ivumbi ryibidukikije - byose bifite akamaro. Nyuma yumwenda wambere, duhita dushyira stucco (umucanga utubutse) mugihe ibishishwa bikiri bitose. Noneho ni ukuzenguruka: gukama, kwibiza, kuniga, gukama. Ibidukikije byumye (ubushyuhe, ubushuhe, umwuka wo mu kirere) ningirakamaro nkibishishwa ubwabyo. Kunyunyuza ibi biganisha ku bishishwa byatsi hamwe nubushuhe bwafashwe, bihinduka umwuka kandi bigaturika mugihe cyo gutemba.
Ikiburanwa: Ingingo ya Nickel ishingiye kuri Alloy Turbine
Aha niho ibitekerezo bihurira n'umuriro. Twari dufite umushinga mugice gito cya nikel ishingiye kuri alloy turbine blade. Ibishashara byari bigoye, hamwe n'imiyoboro yo gukonjesha imbere. Kwiruka kwambere yakoresheje ibyuma bisanzwe byibyuma byoroheje. Igisubizo? Ibyuma byinshi byerekanaga uduce twiza mumpande zikurikira nyuma yo kwangirika muri autoclave. Igikonoshwa cyari gikomeye kandi ntigishobora kwihanganira kwaguka kwashashara. Kunanirwa byari muri sisitemu yo guhuza; yari ikomeye cyane, yoroheje cyane kuri iyi geometrie.
Gukosora byari byinshi-byahinduwe kuri ceramic slurry yo guta ibishashara. Ubwa mbere, twagabanije gato igipimo cya binder mumakoti abiri yambere kugirango twemere akantu gato guhinduka. Icya kabiri, twahinduye stucco kumpoti yambere tujya kumusenyi muke muto, umusenyi wuzuye uruziga kugirango tugabanye ingingo yibibazo. Icya gatatu, twongereye igihe cyo kumisha hagati yamakoti yambere kuri 50%. Yadindije umusaruro, ariko irakora. Igikonoshwa cyari gifite imbaraga zihagije zo gukoresha ibyuma ariko byinjira neza na micro-gutanga kugirango bibeho kwangirika. Ubu bwoko bwo gukemura ibibazo nibisanzwe kumaduka nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), aho ibikoresho bya portfolio kuva kumyuma kugeza kumavuta yihariye biguhatira kubaha gusebanya nkibihinduka, ntabwo bihoraho.
Indi ngingo ifatika: kuri ubu bushyuhe bwo hejuru cyane, igikonoshwa ntigomba kwihanganira ubushyuhe bwo gusuka gusa, ahubwo nubushyuhe bumara igihe kinini nkuko ikigo kinini cyo guteramo gikomera buhoro. Igicucu cyacumuye cyangwa cyoroshe hakiri kare gishobora gutuma ibyuma byinjira, bigakora ubuso butajegajega, bwahujwe ninzozi mbi yo kweza. Inzira ya zircon slurry formulaire, yatejwe imbere mumyaka, yashizweho kugirango igumane ubunyangamugayo kugeza kumupaka, niyo mpamvu dushobora gukemura byimazeyo ibisabwa bisabwa kubice bya cobalt na nikel.
Imitego isanzwe hamwe no kubyumva
Kurenga tekinike ya tekinike, hariho intuition. Igishishwa cyakoreshejwe mumazi menshi yegeranya umukungugu uva stucco na hydrolyzed binder. Igenda iba ndende, ubunini bwayo burahinduka. Ntushobora gukomeza kongeramo amazi kugirango uhindure ubwiza; Kugabanya Ibirimo. Ugomba kuvugurura buri gihe ikigega ukoresheje ibishishwa bishya. Hano hari ahantu heza mubuzima bwikigega aho kiringaniye neza-mubisanzwe nyuma yigihe gito cyo kugarura ubuyanja.
Ikibazo kimwe gikomeje ni amazi atemba arema uruzitiro cyangwa kwiyubaka cyane munsi yikigereranyo cyibishashara. Ibi bikora ubushyuhe butandukanye butandukanye mugihe cyo gusuka, biganisha ku kugabanuka kwicyuma mubyuma aho hantu. Igisubizo ntabwo buri gihe kiba ubwacyo, ariko muburyo bwo kwibiza - rimwe na rimwe ugomba kwibira, kuzunguruka dogere 180, no kongera kwibira kugirango ubone ikote. Ni ugukosora amaboko.
Hanyuma, isano iri hagati yo gusebanya no kurasa nyuma. Igikonoshwa kigomba kuraswa kugirango gitwike ibishashara byose bisigaye kandi bihindagurika no guteza imbere imbaraga zanyuma. Niba formulaire ya slurry yazimye, igikonoshwa kirashobora gutemba cyangwa kumeneka mugihe cyo kurasa. Buri gihe dukora ikizamini cyo kurasa mugikonoshwa uhereye mugice gishya cyangwa formula mbere yo kwiyemeza gukora. Ni politiki yubwishingizi buhendutse. Igikonoshwa cyarashwe kigomba kugira ibara rihamye hamwe na ping isobanutse, yumvikana iyo ikubiswe byoroheje. Kuvuga nabi bisobanura ibibazo - birashoboka imbaraga nke cyangwa micro-crack.
Umwanzuro: Urufatiro ni Byose
Noneho, nyuma yimyaka mirongo itatu muri uno mukino kuri QSY, kuva mubishishwa kugeza kubushoramari bukomeye, niba hari ikintu kimwe cyo ku nyundo, ni iyi: ntuzigere usuzugura icyumba cyuburiganya. Uwiteka ceramic slurry yo guta ibishashara ni amasezerano shingiro hagati yumushashara nicyuma gishongeshejwe. Nibintu bifite imbaraga, bizima bisaba kubaha no guhora twitegereza. Urashobora kugira ibishashara byiza, igishushanyo cyiza cyo gutambuka, hamwe nitanura rya kalibateri, ariko gutobora nabi bizahungabanya byose. Ntabwo ari umurimo ushimishije - akenshi usanga urimo akajagari kandi usubiramo - ariko ubwiza bwibintu byose bikurikiraho bwubatswe, umurongo ku kindi, muri iyo tank. Ubuhanga nyabwo ntabwo ari ukuvanga gusa kurupapuro rwihariye; ni mukumenya kubihindura kubice byigiti uyumunsi, kugirango amavuta asukwa mucyumweru gitaha, hamwe nikibazo wakemuye ariko ushobora kongera kubona muburyo butandukanye. Ubwo ni ubukorikori.
