Uva 'i-sodium silicate sand casting' kwaye iingqondo ezininzi zitsibela ngqo kwinkqubo ye-CO2. Leyo yiklasikhi, enye kuzo zonke iincwadi zezifundo. Vuthela igesi, fumana isikhunta esiqinileyo, uthele. Kodwa ukuba uhleli phantsi ixesha elithile, uyazi ukuba ngumnyango nje. Incoko yokwenene iqala ngokudibanisa, ukuchithwa, kunye nokunyaniseka okukhohlakeleyo malunga nexesha elikhanyayo kunye naxa intlungu epheleleyo ukuyikhupha. Ayisiyondlela iqhinga elinye, kwaye ukuyiphatha njengenye kulapho iivenkile ezininzi, ngakumbi ezintsha, zitshisa iminwe yazo kumaxabiso alahliweyo kunye neendleko zokucoca.
Inyani yeBinder: Ayiyoglasi nje yamanzi
Ukuyibiza ngokuba 'yiglasi yamanzi' kuyenza ibe lula ukusa kwinqanaba lokulahlekisa. Ewe, i-sodium silicate, kodwa i-modulus-umlinganiselo we-SiO2 ukuya kwi-Na2O-yinto yonke. I-modulus binder ephezulu ibeka ngokukhawuleza, inika amandla angcono, kodwa oothixo, ukubuyisela. Ukuba inkqubo yakho yesanti ayilungiselelwanga, uya kuthenga isanti entsha ngomthwalo welori kuba ukonakala kubi. Oku sikufunde kabuhlungu kumsebenzi wexesha elide wokwakha izindlu zokumpompa. Kwakusetyenziswa isidibanisi esiqhelekileyo esingekho kwishelufu, yaye emva kwemijikelo emithathu, isanti yayifana nezigaqa zesamente. Kwafuneka ndiyikhuphe yonke ibhetshi. Ngoku sisebenza ngokusondeleyo nomthengisi wethu weekhemikhali ukuze sidibanise imodyuli esekwe kwi-alloy kunye nobunzima. Ukwenziwa kwentsimbi yecandelo elinzima, unokufuna ukuqulunqwa okwahlukileyo kunodonga olubhityileyo lwentsimbi. Asiyonto yorhwebo; yiresiphi.
Kwaye ke kukho indlela yokuqina. I-CO2 ngumntwana wepowusta, kodwa ithanda ukugasa kakhulu. Ufumana uboya obumhlophe kumphezulu wokungunda ukuba awuchanekanga—carbonation. Iyonakalisa ukugqiba komphezulu. Kwimisebenzi ebalulekileyo, satshintshela kwi-ester hardening kwiminyaka eyadlulayo. Uxuba i-ester yamanzi kunye nesanti edibeneyo ye-silicate, kwaye ibeka ngexesha layo. Ikunika amandla afanayo ngakumbi, umgangatho ongcono, kwaye ngokunyanisekileyo, ulawulo olungaphezulu. Urhwebo-off? Usebenza ngokuchasene newotshi xa sele ixutyiwe. Yongeza umaleko wokucwangcisa ukuba indlela elula ye-CO2 ayinayo. Awunakuvele udibanise itoni kwaye uyiyeke ihlale.
Kulapho iminyaka engama-30-engaqhelekanga kumdlalo, njengale nto uyibonayo kwifemu efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), imiba. Balubonile utshintsho ukusuka kwi-CO2 ukuya kwezi nkqubo zilawulwa ngakumbi. Kwiqonga labo, tsngtaocnc.com, badwelisa iqokobhe kunye nokuphosa utyalo-mali ngaphambili, kodwa ugrumba kancinci kwizakhono zabo kwaye uyazi ivenkile enaloo mbali kuye kwafuneka ilwe neziseko zokugalela isanti, kubandakanya iinkqubo ze-sodium silicate, ngakumbi kwimisebenzi yazo enkulu okanye enye yentsimbi kunye ne-alloy. Ukhetho lwesixokelelwano sokubopha asilomfundo; yinto eyahlula ukuphosa okucocekileyo kwiphupha elibi legumbi lokucoca.
Ukubuyisela Intloko Ebuhlungu: Ixabiso Elingathethwayo
Akukho mntu uthetha ngokubuyiselwa kwesanti ngokwaneleyo xa bekuthengisa kwimiba 'eluhlaza' yezibophelelo ze-silicate. Ayisiyonto ephilayo, akukho msi ombi ngexesha lokugalelwa, eyinyani kwaye idibanisa enkulu. Kodwa isanti echithiweyo lilitye. Ukulungiswa kwakhona koomatshini kaninzi akonelanga; udinga ukubuyiselwa kwe-thermal ukuze waphule ngokwenene ezo bhondi ze-silicate. Lixabiso elikhulu elo. Ukuba umthamo wakho awukuthetheleli oko, ujonge iindleko zokulahla kunye neendleko zesanti entsha yokutya kumda wakho.
Saqhuba amanani kumsebenzi ophakathi kwizibiyeli zezixhobo zemigodi. Ukubunjwa kwakukuhle, komelele njengenkomo. Kodwa ukucoca ... iiyure zokugaya. Kwaye isanti? Sazama ukuyityumza kwaye siyisebenzise kwakhona, kodwa iLOI (Loss on Ignition) yadubula, kwaye ukusasazwa okuziinkozo konakaliswa. Ichaphazele ukuhambahamba kunye nokugqiba kwibhetshi elandelayo. Saye sagqiba ukubetha nje ukulahla isanti esetyenzisiweyo. Yayisisifundo: i-sodium silicate ayisiyonkqubo yesanti emiselweyo kwaye uyilibale njengeenkqubo ezidityaniswe nentlaka. Kuya kufuneka ucwangcise umjikelo wayo wonke wobomi kwivenkile yakho.
Le yingqwalasela ebalulekileyo kwisiseko seenkqubo ezininzi. Inkampani efana QSY, ephethe yonke into ukusuka ekufakeni utyalo-mali oluntsonkothileyo ukuya kumatshini onzima, kufuneka wenze ukhetho olucwangcisiweyo. Basenokugcina ukuphoswa kwesanti ye-sodium silicate ukwenzela izicelo ezithile apho ukomelela kwayo okuphezulu kunye nozinzo lwe-dimensional enkulu, iimilo ezilula zodlula ubunzima bokubuyisela, kwaye basebenzise ukubumba iqokobhe kubunzima obungakumbi, iindawo ezinomthamo ophezulu. Kumalunga nokulungelelanisa inkqubo kwicandelo, hayi ukunyanzela inkqubo enye ukuba yenze yonke into.
Apho ifumana khona ukugcinwa kwayo: Intshatsheli yobunzima obunzima
Ngoko kutheni uzikhathaza? Kuba kwimisebenzi ethile, akukho nto iyenye ithe ngqo okanye ingabizi kakhulu. Enkulu, enye-off okanye ephantsi-volume castings zentsimbi. Cinga ngeziseko zezixhobo zoomatshini, izikhewu ezinkulu zegiya, okanye izakhelo zoomatshini abanzima. Udinga amandla amakhulu okubumba ukuze ubambe ubunzima bentsimbi ngaphandle kokuguqulwa, kwaye ufuna isikhunta esingavelisi igesi eninzi xa intsimbi iyibetha. Isanti ye-sodium silicate, ngakumbi ngokuqina kwe-ester, ihambisa loo nto.
