Say pangipelag na buer ed saray balbula

Sand casting: Say sand casting ya kaslakan ya uusaren ed industriya na balbula et nayarin naapag met ed nanduruman klase na buer a singa sayambetel a buer, amagan buer, danum a salming a buer tan furan resin ya anggapoy luto a buerunong ed nanduruman binder.

(1) Say green sand et sakey a paraan na panagmolde ya say bentonite so uusaren bilang binder ed kimey. Saray katangian to et: say asumpal ya sand mold et agla kaukolan ya pamaraan odino ondalan ed espisyal ya hardening treatment, say sand mold et walay pigaran wet strength to, tan say sand core tan shell to et walaan na mas maabig iran konsesyon, ya kombeniente parad panaglinis na casting tan panagpelag na buer. Say inkaepektibo na panagmoldi et atagey, antikey so siklo na panaggawa, tan abeba met so gastos ed materyales, ya kombeniente parad pangorganisa na produksyon ed assembly line. Saray disbentaha to et: saray casting et mainomay ya nawalaan na depekto a singa saray pores, sand inclusions, tan sticky sand, tan say kalidad na casting, lalo la ed kalidad na loob, et aliwan magenap.

(2) Say amagan buer et sakey a proseso na panagmodelo ya uusaren so pitek bilang binder, tan say daiset a bentonite so makapaaligwas ed biskeg na basa to. Saray katangian to et: say sand mold et kaukolan ya pamaraan, walay maong ya air permeability tan air dispersion, aliwan mainomay ya makagawa na depekto a singa say sand washing, sand sticking, tan pores, tan say kalidad na loob na casting et medyo maong met. Saray disbentaha to et: nakaukolan so kagawaan ed panag-amaga na buer, tan say siklo na produksyon et medyo andukey.

(3) Say sodium silicate sand et sakey a paraan na panagmolde ya uusaren so water glass bilang binder. Saray katangian to et: say water glass et walay gagala ton automatikon onawet kayari na pakaabet na CO2, tan nayarin walaan na nanduruman bentaha tan bentaha ed gas hardening modeling tan core making. Balet, wala ray disbentaha a singa say makapuy ya pakatumba na shell, mairap ya linisan so buer parad saray casting, tan abeban recycling rate na nausar lan buer.

(4) Say furan resin no-bake sand molding et sakey a paraan na panag-cast ya walay furan resin bilang binder. Diad temperatura na kuarto, say molding sand et onkupas lapud kemikal ya reaksion na binder diad silong na aksion na curing agent. Saray katangian to et: say sand mold et ag kaukolan ya pamaraan, ya mamapatikey ed siklo na produksyon tan makatipid na enerhiya. Say resin molding sand et mainomay ya i-compact tan maong so collapsibility to, tan say molding sand na saray casting et mainomay met ya linisan, atagey so dimensional accuracy na casting, tan maong so surface finish to, ya makapaaligwas a maong ed kalidad na casting. Saray disbentaha to et: atagey met so kalidad na hilaw ya buer, say pasen na produksyon et walaan na medyo makapaermen ya angob, tan atagey met so presyo na resin. Proseso na panaglaok na furan resin self-hardening sand: Say resin self-hardening sand et mas maabig no gawaen panamegley na tuloytuloy ya sand mixer, ya idagdag so hilaw ya buer, resin, curing agent, tan arum nira, tan maples ya ilaok iratan. Ilaok tan usaren anggan kapigan. Say inkauksoy na pangiyarum na nanduruman hilaw a materyales no manlalaok na resin sand et onia: orihinal a buer + curing agent (p-toluenesulfonic acid aqueous solution) – (120-180S) – resin + silane – (60-90S) – buer (5) Tipikal a klase na buer Proseso na panag-cast: precision casting.
