Xa kufunwa iindawo zentsimbi ngokuphoswa kwewax elahlekileyo, abathengi bahlala bejongana nesigqibo esingundoqo: ukukhetha inkqubo yeqokobhe leglasi yamanzi okanye inkqubo yeqokobhe le-silica sol yotyalo-mali. Zombini zezokulahleka kwewax, kodwa isibophelelo esisetyenziselwa iqokobhe leceramic sidala izithuba ezinkulu kumgangatho ongaphezulu, ukuchaneka komda, umjikelo wemveliso, kunye neendleko zizonke. Ukukhetha inkqubo yeqokobhe engalunganga kunokukhokelela kwiindawo ezikhatywayo, ukugqithiswa kohlahlo lwabiwo-mali, okanye ixesha elibekiweyo lokuhanjiswa. Esi sikhokelo siqhekeza zombini ukuhamba komsebenzi, sithelekisa iimethrikhi eziphambili zokusebenza, kwaye sikunceda ukuba ukhethe indlela efanelekileyo yokulahla i-wax yecandelo lakho.
Yintoni i-Water Glass Casting?
Ukugalelwa kweglasi yamanzi lutyalo-mali oluqhelekileyo olusebenzisa iglasi yamanzi (i-sodium silicate) njengesibophelelo sokwakha iqokobhe leceramic. Ihlala isetyenziswa ngokubanzi kumacandelo esinyithi amashishini ngokubanzi ngenxa yokusebenza kwayo okuzinzileyo kunye nomgangatho ophantsi wemveliso.
Iqokobhe leglasi lamanzi elenza ukuhamba komsebenzi
Ulandelelwano lwesakhiwo seqokobhe lulandela la manyathelo angatshintshiyo:
- Hlanganisa iipateni zewax kumthi wokuvala umthwebeba
- Dipha indibano yewax kwi-slurry exutywe ne-binder yeglasi yamanzi kunye nomgubo we-refractory
- Faka i-stucco yegranular phezu komgangatho omanzi we-slurry
- Gxininisa indibano egqunyiweyo kwi-ammonium chloride hardener ukuze kunyangelwe ngokukhawuleza imichiza
- Phinda ukudipha, ukufaka istucco kunye nokuqina ukwakha ubungqingqwa obaneleyo beqokobhe
- Gqibezela i-dewax yomphunga ukunyibilikisa i-wax yangaphakathi
- Ukutshisa igobolondo eligqityiweyo, uze uthele isinyithi esityhidiweyo
Ukusabela kokuqina kweekhemikhali kukhawulezisa ukubunjwa kweqokobhe kakhulu, eyona nzuzo inkulu yenkqubo yeglasi yamanzi.
IiPropati eziQhelekileyo kunye neealloyi ezifanelekileyo zokuSasa ngeglasi yamanzi
Iigobolondo zeglasi zamanzi zisebenza kakuhle kwi-carbon steel, intsimbi ephantsi ye-alloy kunye namabakala amaninzi aqhelekileyo angenasici. Ngokuqhelekileyo ikhethwa kwi-medium to heavy structural castings kunye nokunyamezela okuphakathi kunye neemfuno zomhlaba. Ayilokhetho lokuqala kwiindonga ezibhityileyo kakhulu okanye iialloyi zebakala eliphezulu lokuchaneka kwe-aerospace.
Yintoni iSilica Sol Investment Casting?
I-silica sol investment casting yinkqubo yokuphosa i-wax echaneke kakhulu esebenzisa i-silica sol njengesibophelelo seqokobhe leceramic. Yeyona ndlela iphambili yokhetho lwamacandelo achanekileyo apho ukunyamezelana okuqinileyo kunye nemigangatho egudileyo njenge-cast inyanzelekile. Abanye abathengi bakhangela igama elithi "investment casting silicone sol Foundry" xa befuna le nkqubo.
Iqokobhe leSilica Sol lenza ukuhamba komsebenzi
Ulandelelwano lulonke luyafana nezinye iindlela zewax ezilahlekileyo, kodwa indlela yokunyanga yahluke ngokupheleleyo:
- Beka iipateni zewax kumthi we-wax sprue
