I-Uns K93600 Invar 36 Ribbon Precision Expansion Alloy Flat Wire
Izindleko ze-K93600 I-Invar36 I-Ribbon Precision Expansion Alloy Flat Wire
(Igama Elijwayelekile:I-Invar, FeNi36, Invar Standard, Vacodil36)
4J36 (I-Invar), eyaziwa nangokuthi i-FeNi36 (64FeNi e-US), ingxubevange ye-nickel-iron ephawuleka nge-coefficient yayo ephansi ehlukile yokunwetshwa kwe-thermal (CTE noma α).
I-4J36 (Invar) isetshenziswa lapho kudingeka khona ukuzinza kwe-dimensional ephezulu, njengamathuluzi anembayo, amawashi, ama-seismic creep gauge, amafreyimu emaskhi ethunzi kamabonakude, ama-valve kumamotho, namawashi e-antimagnetic. Ekuhloleni umhlaba, lapho kufanele kwenziwe izinga lokuqala (lokunemba okuphezulu) kokuphakama, izisebenzi Zezinga (induku yokulinganisa) ezisetshenziswayo zenziwe nge-Invar, esikhundleni sokhuni, i-fiberglass, noma ezinye izinsimbi. Ama-Invar struts asetshenziswa kwamanye ama-piston ukukhawulela ukwanda kwawo okushisayo ngaphakathi kwamasilinda awo.
I-4J36 sebenzisa i-oxyacetylene welding, i-arc welding kagesi, i-welding nezinye izindlela zokushisela. Njengoba i-coefficient yokunwetshwa kanye nokwakheka kwamakhemikhali engxubevange kuhlobene kufanele kugwenywe ngenxa yokuthi i-welding idala ushintsho ekubunjweni kwengxubevange, kungcono ukusebenzisa izinsimbi zokugcwalisa welding we-Argon arc okungcono iqukethe i-0.5% kuya ku-1.5% titanium, ukuze ukunciphisa i-weld porosity kanye nokuqhekeka.
