1. Igobolondo lengilazi yamanzi

Le nqubo ikhiqizwa eChina cishe iminyaka engama-50.Ngemva kwengxenye yekhulu yemizamo engapheli yozakwethu embonini yokutshala izimali, ukusetshenziswa nokucwaninga kobuchwepheshe begobolondo lengilazi yamanzi sekufinyelele izinga eliphezulu.Ngokuhamba kweminyaka, amandla egobolondo lengilazi yamanzi aphindwe kabili ngenxa yokuthuthukiswa kwe-refractory yegobolondo elingemuva kanye nokuthandwa nokusetshenziswa kwe-hardener entsha.Izindleko eziphansi, umjikelezo wokukhiqiza omfushane kakhulu, ukusebenza okuhle kakhulu kwe-shelling kanye nokungena okuphezulu kuseyizinzuzo zanoma ibuphi obunye ubuchwepheshe bokugoqa.

2. Igobolondo elihlanganisiwe

Uma kuqhathaniswa negobolondo lengilazi yamanzi, ikhwalithi yangaphezulu ye-casting iye yathuthukiswa kakhulu, futhi ukugoqa kwendawo, ukukhubazeka kwendawo kanye nezinga lokulungisa liye lancipha.Ifanele insimbi engagqwali, insimbi engashisi nezinye izinsimbi ezisezingeni eliphezulu.Umjikelezo wokukhiqiza mfushane kakhulu kunalowo wegobolondo le-wax ye-silika sol lokushisa eliphansi, elifana negobolondo lengilazi yamanzi.

3、 I-Silicasol (i-wax yokushisa ephansi) igobolondo

Lolu hlelo luhambisana nezimo zezwe.Iyakwazi ukuzivumelanisa nezimo nokuphakama okukhulu lapho isakaza ama-castings amakhulu naphakathi nendawo angaphezu kuka-1kg, ikakhulukazi lawo angaphezu kuka-5kg.Uma kuqhathaniswa negobolondo eliyinhlanganisela, ikhwalithi yegobolondo izinzile, ikakhulukazi ukunemba kosayizi wokuphonsa kuphezulu, akukho silicate ye-sodium, izinga lokushisa eliphakeme lisebenza kahle, ngemuva kokubhaka ku-1000-1200 ℃, linokungena okuphezulu nokumelana nokukhasa, okungase isetshenziswe ezingxenyeni ezinezindonga ezincane.Izingxenye ezine-LED, izingxenye ezincane nezimaphakathi ezinesakhiwo esiyinkimbinkimbi, zingaphinda zikhiqize izingxenye ezinkulu ezinesisindo esingu-50-100kg, njengepompo yamanzi, i-impeller, njll. Igobolondo lomhlahlandlela, umzimba wepompo, umzimba we-valve yebhola, ipuleti le-valve, njll. izingxenye ezincane ezinodonga ezinodonga noma izingxenye ezinkulu, igobolondo lemfoloko noma igobolondo eliphakamisayo lingathululwa ngqo phambi kwesithando somlilo, futhi isivuno esiphezulu singatholakala.

4. Igobolondo le-Silicasol (i-wax yokushisa ephakathi)

Lena inqubo evamile yokukhiqiza yokulingisa okunembayo emhlabeni.Inekhwalithi yokulingisa nezinga lokulungisa le.Ilungele ikakhulukazi ukulingisa okuncane nokuphakathi nendawo (2-1000g) enobulukhuni obuphezulu kanye nokunemba kobukhulu.Kodwa-ke, ngenxa yomkhawulo wemishini nezindleko, akuvamile ukusetshenziselwa izingxenye ezinkulu neziphakathi (5-100kg)
