Reka tuvugishe ukuri, iyo abantu benshi bumvise 'silica sol ishoramari casting', bashushanya ibyuma byindege bitagira inenge cyangwa ibihangano bikomeye. Uru ni uruhande rwiza. Ukuri, gusya burimunsi, ni ugukora igikonoshwa cyizewe kidacika, kidasinzira, cyangwa kigumana ivu ryinshi, kubice bikunze kugenda bitaboneka. Ninzira aho binder-silika sol-nibintu byose kandi ntakintu icyarimwe. Amarozi ntabwo ari muri silika ya colloidal ubwayo, ahubwo nukuntu urongora hamwe na stucco, ibidukikije byumye, kandi mvugishije ukuri, uko ucunga ibiteganijwe. Amaduka menshi atekereza guhindukira kuri a silika sol ishoramari inzira ni kuzamura mu buryo butaziguye kuri buri kintu. Ntabwo aribyo. Nigikoresho, kandi cyoroshye kuriyo.
Intangiriro y'Igikonoshwa: Birenze Guhuza
Ndibuka igihe twahinduye bwa mbere imirongo imwe kuva muri Ethyl silicate kuri silika sol. Ikibanza cyo kugurisha cyari hafi kurangiza neza nimbaraga zo hejuru. Icyo batashimangiye bihagije ni ukurwanya ikirere. Hamwe na silike ya Ethyl, ufite akayabo. Hamwe na silika sol, ahantu humye hahinduka ikintu gikomeye. Ubushuhe bugereranije n'umwuka wo mu kirere ntabwo ari ibintu byo guhumuriza gusa; bategeka igipimo cya gelation ya sol. Byihuta cyane, kandi ubona ikote ryoroshye, ryacishijwe bugufi. Biratinda cyane, kandi umusaruro wawe uzunguruka uhagarara.
Twize ibi inzira igoye kumurongo wimibiri ya valve kubakiriya. Kurangiza byari byiza, ibipimo byukuri byari bigaragara, ariko twari dufite igipimo cya 30% cyo gutsindwa mugihe cyo kwangiza. Igikonoshwa cyasaga neza. Ikibazo? Twari dufite ubushyuhe bwinshi, kandi amakoti y'ibanze ntiyari yuzuye neza mbere yuko dushyira amakoti yinyuma. Mugihe cya autoclave dewaxing, umuvuduko wamazi wasangaga izo ntege nke, zifite igice. Igisubizo cyabaye kuvunika ibishishwa bya catastropique, ntabwo amazi meza yatunganijwe twari dukeneye. Ntabwo byari ibintu byananiranye; byari inzira yo kunanirwa ubumenyi.
Aho niho ubuhanga nyabwo buri - ntabwo ari ukugura silika sol, ahubwo mukubaka sisitemu irizengurutse. Nukumenya ko ifu ya zircon kumpoti yambere ikenera sol itandukanye pH ihinduwe nkiyo ushobora gukoresha kumyenda ya aluminosilicate stucco nyuma. Ni chimie yashizwe kurwego rwinganda.
Aho Irabagirana Mubyukuri (Kandi Aho Itari)
Kubitera ubwoba byose, silika sol ishoramari ni Ntibishoboka Kuri Porogaramu. Tekereza ibice bito, ibice byimbere byimbere, cyangwa ibivanze byoroshye cyane. Igikonoshwa cya monolithic ceramic ukura mubikorwa byiza bya silika sol byakozwe neza cyane kandi byoroshye. Turayikoresha hafi kubikorwa byubushyuhe bwo hejuru-akazi-nikel-ishingiye kuri nikel. Igikonoshwa gihamye mugusuka ubushyuhe burarenze, bigabanya ibyuma-shell reaction kandi biguha icyuma gisukuye.
Narebaga umushinga utanga isoko, Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), urutonde rwubushobozi bwibanze. Hamwe nimyaka 30 yabo yo gutara no kuyitunganya, urashobora guhitamo uburyo bwabo bwibyuma bidafite ingese hamwe na casting idasanzwe yisunga cyane kuri sisitemu ikuze ya silika sol. Ntabwo ari ikintu ushiramo; ni icyemezo. Kubikoresho bisanzwe bya karubone cyangwa icyuma cyoroshye? Kurenza urugero. Igiciro nigihe cyigihe nticyemewe. ROI ije mugihe urimo utera ibyuma bidafite ingese hamwe na vanse yoroheje kuruta igiceri, aho ubudahemuka buke butaganirwaho.
Gukoresha Intoki
Iyi ni ingingo ikunze kubura. Uwiteka gushora imari inzira ntabwo irangirira kuri shakeout. Uruganda rwiza rutekereza kubijyanye no gutunganya guhera. Silica sol shell mubisanzwe itanga ubuso bwiza burangije, bwumvikana neza. Ariko bivuze kandi ko uruhu rwo guteramo rukomeye kandi rwinshi. Ibi bigira ingaruka kuburyo ibikoresho bya CNC bifatanya no gukata kwambere. Tugomba guhindura igipimo cyibiryo ninzira yibikoresho kubice biva kumurongo wa silika sol ugereranije nibindi bikorwa byacu.
Igikorwa gihuriweho nka QSY, gikora ibishishwa byombi, gushora imari, hamwe no gutunganya CNC munsi yinzu, bifite inyungu zitandukanye hano. Itsinda ryabo ryo gutunganya ntabwo ryakira agasanduku k'umukara; barimo kubona igice amateka yimikorere bashobora kuba bumva. Bazi ko ibisigisigi by'irembo kuri silika sol casting bishobora kuba bifite umwirondoro utandukanye gato, kuburyo bashobora gukora gahunda ya CNC. Uku gufunga-gufunga kuva kubumba kugeza kumashini niho hubakwa ubuziranenge nubushobozi nyabwo, atari mumashami ya casting yonyine.
Ingano yumucanga mubikoresho
Nta nzira itunganye. Kubabara umutwe hamwe na silika sol, usibye kubyerekeranye nikirere, nuburyo bworoshye bwigikonoshwa. Gutwikwa ni ngombwa. Igikoresho cyose gisigaye cya silika gishobora gusiga ikirahuri, gisigara gisigara hejuru yumukino, cyane cyane muburyo bwo kongera kwinjira. Iyi ntabwo ari ingano yumucanga ushobora guturika; byahujwe. Twigeze kugira icyiciro cyamazu ya pompe aho iki gisigara cyafatiwe mumutwe wimbere. Byari inzozi gukosora, hafi yo gukuraho amashanyarazi.
Aha niho ishoramari muri gushora imari ibona ukuri. Umwirondoro wawe wo gutwika ntabwo ushizeho kandi wibagirwe. Igomba guhuzwa nigikonoshwa hamwe na alloy. Ibyuma biremereye cyane bikenera uruziga rutandukanye nubushyuhe bwa aluminiyumu yoroheje kugira ngo ikureho binder. Nubundi buryo bwo kugenzura ibikorwa bitandukanya iduka ryakazi nububiko bwuzuye.
Icyerekezo gifatika
None, silika sol ejo hazaza? Kubunyangamugayo buhanitse, ibice byuzuye, rwose. Ninkingi yindege, ubuvuzi, hamwe ninganda zo mu rwego rwo hejuru. Ariko ntabwo ari ubwoba rusange. Icyemezo cyo kugikoresha kigomba kuba kubara tekiniki nubucuruzi: kurangiza hejuru isabwa (Ra agaciro), reaction ya alloy, igice cya geometrie, nigiciro cyemewe kuri buri gice.
Iyo usuzumye umufatanyabikorwa kubikorwa nkibi, ntabwo uba ugura casting gusa. Urimo kugura ibiti byo kugenzura ibidukikije, inyandiko zabo zo kubungabunga bidatinze, imbonerahamwe yabyo. Urimo kugura imyaka mirongo yimyitozo yashinze imizi, nkibyo wakuramo uhereye kumuntu umaze igihe kinini mumurima. Agaciro nyako mubikorwa nka silika sol ishoramari ntabwo abikwa muri banki, ahubwo yibukwa mumitsi yibuke abatekinisiye naba injeniyeri barwanye intambara zayo, bakigira kubyo yananiwe, kandi bagakoresha imbaraga zayo nyinshi kugirango batange ibice bidashobora gukorwa mubundi buryo.
