Nzira Yekugadzirisa Sei Kunhuhwirira Kwejekiseni Molding Zvigadzirwa?

Injection molding vagadziritenga zvimedu zvepurasitiki zvinokwanisa, inova vimbiso yakakosha yekuona kuti zvigadzirwa zvekuumba jekiseni hazvina kunhuwa.Kana ari mamwe mapurasitiki, ane kumwe kunhuwa, vanogadzira jekiseni vanogadzira vanofanirwa kutora matanho vasati vagadzirwa.

Majekiseni ekuumba zvigadzirwa hazvingodiwa chete kuti uve unokwanisa, asi kana akagadzirwa jekiseni ekuumba zvikamu zvine kunhuhwirira kwakasiyana, zvinozoitawo zvakaipa kune vatengi.Kunyanya, vamwe vanogadzira majekiseni ekugadzira majekiseni vanoshandisa zvimedu zvepurasitiki, uye kuwedzera kunhuhwirira kunobata zvakananga kutenga kwevatengi.Naizvozvo, zvigadzirwa zvakagadziriswa kuburikidzajekiseni moldinoda kuvimbiswa kuti haina kunhuhwirira kunokuvadza.

1. Kunyatsodzora kushandiswa kwezvinowedzera

Iyo catalyst tertiary amine inoshandiswa mukugadzirwa kwepolyurethane foam ichaunza kunhuhwirira kwakasimba uye mhute pahwindo remukati remota.Tinogona kuwana anotsiva aya maamine kushandisa polyhydroxy compounds.Polyhydroxy compounds hazvisi chete zvikamu zve polyurethane molecular chain, asiwo ane catalytic chiitiko.Mamwe mapolyhydroxy compounds anogona kutotsiva hafu yetertiary amine catalyst, Kunhuhwirira kwezvigadzirwa zvekuumba majekiseni kunopera simba.

2. Sarudza yakawanda yakachena resin

Mune akawanda epurasitiki molds, kunyanya muPVC, styrene, poly (ethyl acetate) uye acrylate, iyo yakasara inoteedzera huwandu hwemonomers ichava nekunhuhwirira kusingafadzi.Kana iyo inonhuhwirira resin yakasarudzwa, mhedzisiro ichava nani.

3. Ngwarira kushandiswa kweadsorbent

Kana mazeolite mashoma akazadzwa mupolymer, kunhuhwirira kwezvinhu kunogona kubviswa.MaZeolite ane yakawanda yekristaro hollowness, iyo inogona kutora iwo madiki egasi mamorekuru ane hwema.

Injection molding vagadziri vanotenga vanokwanisa epurasitiki zvimedu, inova vimbiso yakakosha yekuona kutijekiseni kuumba zvigadzirwahadzina hwema.Kana ari mamwe mapurasitiki, ane kumwe kunhuwa, vanogadzira jekiseni vanogadzira vanofanirwa kutora matanho vasati vagadzirwa.
