Iyo wunvise 'colloidal silica ishoramari casting', abantu benshi bahita batekereza kuri binder-gusa ayo mazi yamata uvanga mubitotsi. Aho niho hantu hambere aho ibitekerezo bikunze kugenda nabi. Ntabwo ari kole gusa; ni umugongo wose wububiko bwigikonoshwa, nuburyo ucunga chimie nogukoresha byerekana niba ubona casting itagira inenge cyangwa ububiko bwuzuye ibisigazwa. Nabonye amaduka asuka amafaranga muri aluminiyumu gusa kugirango mbuze byose ku gishishwa cyiza gisenyutse cyangwa cyegeranye. Umukino nyawo uri muri siloidal silica igabanije ingano yikwirakwizwa, pH itajegajega, kandi mvugishije ukuri, disipuline yo kugenzura inzira, benshi basuzugura kugeza bahuye nikibazo gikomeye.
Uruhare Rudasobanutse rwa Siloidal Silica
Reka tumenye neza. Siloidal silika ntabwo igicuruzwa kimwe. Ibintu ukura kubatanga ibintu bitandukanye bitwara ukundi. Ibi twabyize inzira igoye imyaka yashize. Twahinduye kuri silika ihendutse, idahwitse ya siloidal ya silika kubikorwa byacu byo guta ibishishwa, twibwira ko ibisobanuro biri kumpapuro byari hafi bihagije. Ibirimo sodium byari hejuru cyane. Igisubizo? Nyuma yicyiciro, ikoti ryambere ryateje micro-crazing. Ntabwo bihita bigaragara, ariko mugihe cy'ubushyuhe bwo hejuru, utwo dusimba duto twakwirakwiriye. Ibyuma byanyuma, cyane cyane mubice bigoye byuma, byerekanaga ibyuma byinjira. Igihombo cyuzuye. Nibwo yakanze: ionic ituze hamwe nibirimo Na2O muri binder ni ibipimo bitaganirwaho. Ntabwo ari ibicuruzwa.
Iyi sano ihuza muburyo bwo gushora imari idasanzwe nka nikel. Iyi mavuta ifite ingingo zo gushonga cyane kandi zirakora bidasanzwe. Niba igikonoshwa kitavunitse kandi gihamye, urabona ibyuma-shell bikorana - inenge mbi yitwa slag gushyiramo cyangwa gutobora hejuru. Silika-isukuye cyane, alkali nkeya ya siloidal silika irakomeye hano. Ikora urusobe rukomeye, rwinshi rwa silika nyuma yo kurasa. Ndibuka umushinga wibikoresho bya turbine aho twakoresheje binder isanzwe; kurangiza hejuru ntibyari byemewe. Guhindura umudozi, silika Sisitemu hamwe no gukwirakwiza uduce duto twakemuye. Shitani iri murirambuye.
Urabona ibigo nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) hamwe nimyaka mirongo itatu mugushushanya no gushora imari. Babimenye neza. Iyo urimo ukorana na cobalt ishingiye kuri alloys umunsi kumunsi, ntushobora gufata binder nkigitekerezo. Ibikorwa byabo byigihe kirekire byerekana gusobanukirwa byimbitse, bifatika kubijyanye niyi mikoranire wunguka gusa kubikorwa byongeye kugaruka no gukemura ibibazo.
Igenzura ryibikorwa: Aho Theory Ihurira Igorofa
Nibyiza, ufite rero binder nziza. Umutego ukurikiraho ni icyumba cya salurry ibidukikije. Kugenzura ubushyuhe n'ubushuhe. Birasa nkibanze, ariko nabaye mubishingwe aho ibi nibitekerezo. Siloidal silika ishingiye kumurongo irakomeye. Niba iduka rishyushye cyane, geles yihuta cyane, ibishishwa byijimye, hamwe nubunini bwa coating yawe ntibihuye. Ubushuhe bukabije, kandi igihe cyo gukama hagati yamakoti kirarambuye, cyica injyana yawe yumusaruro. Twagize icyi aho AC yananiwe mucyumba cyihuta. Umusaruro wose wa gushora imari ibishishwa kumibiri ya valve byagombaga gukurwaho kuko ikoti ya primer yumye vuba, bigakora intera idakomeye hamwe na stucco ikurikira.
Uburyo bwo kwibiza no gutobora nubundi buhanzi. Ikoti rya mbere ni byose. Irakeneye kwigana neza ibishashara birambuye. Dukoresha ifu nziza ya zircon ivanze na silika ya colloidal kuri iyo koti yambere. Ariko intumbero yumukozi wibikoresho igomba kuba yibanze. Guto cyane, kandi ubona ibituba nubusa hejuru yubuso. Byinshi cyane, kandi ibishishwa biriruka, birema utuntu duto. Ntabwo arikintu washyizeho rimwe ukibagirwa. Igishashara cyibishashara, ubushyuhe bwacyo, ndetse nubutumwa bwo kurekura bwakoreshejwe ku rupfu, byose bigira ingaruka. Ni uguhindura buri gihe.
Kuma. Guhumeka ikirere ku gahato birasanzwe, ariko umwuka wo mu kirere ugomba kuba laminari, ntabwo ari umuvurungano. Ntushaka ivumbi riva hasi (akenshi ryuzuyemo ibikoresho bya stucco byabanje) ryishira mu ikoti ritose. Twubatse akazu koroheje keza-kotsa kumisha amakoti yambere, kandi igipimo cyinenge kivuyemo cyaragabanutse kuburyo bugaragara. Ibi nibidashimishije, bishora imari-shusho itandukanya inzira yizewe nakajagari.
Ikiburanwa: Ingingo ya Shell ya Geometrike igoye
Fata ingorabahizi zikomeye, ibyuma byoroheje, byimbitse. Ikibazo ntabwo ari ugukora igikonjo gusa bihagije; ituma byemerwa bihagije kugirango imyuka ihunge mugihe cyo gusuka no gutwikwa. Aha niho imiterere ya gelo ya siloidal silika ihuza urufunguzo. Niba uhagaritse cyane kugirango ubone umwanya muremure wakazi, urashobora guhungabanya mikorobe ya gel nyuma yo kurasa. Ihinduka cyane.
Twagerageje kongeramo ibintu byiza cyane, bigenzurwa byumuti utose kandi duhindura imiti ya gelline (ubusanzwe umunyu wa alkali) kugirango duhuze neza ibi. Intego yari igiceri cyatsinze ibizamini byimbaraga zisanzwe ariko kandi bifite gaze yo hejuru. Iterambere ryaturutse ku kutareba gusa urupapuro rwerekana amakuru, ahubwo rwaturutse ku gukora ibizamini byacu bwite byinjira kuri shell shell. Twahujije ibice bitandukanye bya slurry hamwe nibisubizo nyabyo byo guteramo ibyuma. Ibyatanzwe byari akajagari, ariko icyerekezo cyari gisobanutse: ubunebwe buke bwo hasi, bwashyizwe mu makoti y'ibanze yoroheje, byatanze uburyo bwiza bwo kurasa kuri ibyo bice bikomeye.
Ubu bwoko bwo gukemura ibibazo nintandaro yiterambere Igikonoshwa. Ntabwo ari igitabo. Nibyerekeye gukora base yawe yimbere yimpamvu n'ingaruka. Isosiyete nka QSY, izobereye mu gutunganya no gutunganya CNC, birashoboka ko ifite ibitekerezo byoroshye. Bashobora gukora imashini ya casting, bakabona inenge yo munsi yubutaka bwibibazo byigikonoshwa, hanyuma bakayikurikirana mugice cyihariye cyangwa cyumye. Ubwo bushobozi buhuriweho burakomeye.
Ikintu kivanze: Impamvu ibikoresho byerekana guhitamo guhuza
Ibi binzanye mubikoresho. Gukorana nicyuma ni isi imwe; gukorana na superalloys ikora nibindi. Kuri nikel cyangwa cobalt ishingiye ku mavuta, igikonoshwa ntigomba gukomera gusa, ahubwo no muburyo bwa chimique. Amashanyarazi menshi-alumina akoreshwa kenshi mumakoti yinyuma. Ariko binder-silika ya siloidal-ni matrike yisi yose ifata hamwe. Umwanda uwo ari wo wose cyangwa guhungabana hano ni ahantu hashobora gutsindwa kuri 1500 ° C +.
Twigeze kugira ikibazo cyo gutobora ibyondo hejuru nini, iringaniye ya plaque idafite ibyuma. Igikonoshwa cyasaga neza mbere yo gusuka. Ikibazo cyari uburyo bwo kwagura ubushyuhe budahuye hagati ya siloidal silika gel hamwe nuwuzuza ibintu muri kote yo mumaso. Binder ubwayo yari ikomeye cyane nyuma yo gukama. Igisubizo cyarimo kuvanga ijanisha rito ryibicuruzwa bya silika itandukanye hamwe na selile yahinduwe muburyo bwambere. Yashizeho urusobe rwinshi rwa gel rushobora kwakira ibibazo byumuriro utarinze. Ubu ntabwo aribwo buryo busanzwe. Byari igisubizo cyavutse kubikenewe.
Uru rwego rwibintu byihariye byo kurwanya imihindagurikire y'ikirere ni ngombwa. Kuri Urubuga QSY, batondekanya akazi kabo hamwe na alloys. Umuntu uwo ari we wese muri uru rwego azi ko ayo magambo yerekana isomero ryimbitse, rifite intoki ku isomero ryibikorwa kuri buri muryango wibintu. Sisitemu ya siloidal silika ya cobalt ivanze izaba ifite nuance ugereranije nimwe mubyuma bisanzwe bya karubone. Irashobora kuba ikirango gitandukanye, uruvange rutandukanye, cyangwa igenzurwa ryitondewe ryibipimo byoroshye.
Ibitekerezo byanyuma: Nuburyo bwa sisitemu, ntabwo ari ingirakamaro
Noneho, kuzinga ibi, urufunguzo rwo gufata colloidal silica ishoramari ni uguhagarika kureba silika ya siloidal nkibikoresho byaguzwe gusa. Nibintu nyamukuru bigize sisitemu yunvikana, yuzuzanya. Ibishashara, ibidukikije, ifu yangiritse, umucanga wa stucco, protocole yumye, hanyuma, amavuta asukwa - bose bavugana na binder. Imyitwarire ya binder niyo nzira yanyuma.
Ubuhanga nyabwo buri mu gusobanura ibimenyetso. Impinduka nkeya mugihe cyo gutemba. Itandukaniro rito mumurabyo wikoti yumye. Imbaraga ntoya ihindagurika mugice cyipimishije. Ibi nibintu bikubwira niba inzira yawe igenzurwa. Nibyiza, rimwe na rimwe birababaje. Nta gisubizo kimwe kiboneye, gusa igisubizo cyukuri kububiko bwawe bwihariye, ibikoresho byawe, hamwe nibicuruzwa bivanze.
Niyo mpamvu kuramba muri ubu bucuruzi, nkamateka yimyaka 30 yikigo nka QSY, nikimenyetso cyizewe. Bisobanura ko bishoboka ko bazengurutse ibyo bibazo, bakabona ibisubizo byabyo, kandi bagahindura inzira zabo. Kubantu bose binjiye muribi, wubahe inzira ya siloidal silika. Shora mu gupima ibikoresho byerekana ibipimo. Andika byose. Witegure kwanduza amaboko yawe no kugira ibyo uhindura. Itandukaniro riri hagati yinyungu nigihombo akenshi riri muri ayo mata yera yera nuburyo uhitamo kuyacunga.
