Parizvino, vazhinji vanogadzira jekiseni mold kugadzira vanonyanya kushandisabakelite jekisenikuumba michina uyejekiseni repurasitikikuumba michina.Pane misiyano yakasiyana pakati peDewei yekukanda bakelite jekiseni rekugadzira michina uye epurasitiki jekiseni rekuumba michina.Bakelite is PF (phenolic resin)Bakelite imhando yepurasitiki yepakutanga, iyo yakagadzira kugadzirwa kweindasitiri muUnited States muna 1910. Ngationei kuti musiyano chii?
Zvigadzirwa zvekugadzira bakelite zvinonyanya kushandiswa phenols uye aldehydes, uye phenol uye formaldehyde zvinowanzoshandiswa.Iwo anowanikwa ne polycondensation pasi pe catalysis yeasidhi, alkali uye zvimwe zvinokonzeresa.Kugadzirwa kwemaindasitiri kunonyanya kusanganisira yakaoma muitiro uye wet process.
Phenol uye aldehyde inogona kuburitsa marudzi maviri ePF pasi pechiito chezvakasiyana zvinokonzeresa: imwe inonzi thermoplastic PF uye imwe iri thermosetting PF.Iyo yekutanga inogona kurapwa muchimiro chemuviri chete nekuwedzera kurapa mumiririri uye kupisa, nepo iyo yekupedzisira inogona kuve chimiro chemuviri sekureba kwekudziya pasina kurapa mumiririri.
Kunyangwe iyo thermoplastic pf kana thermosetting PF, chete network yekuchinjana inoumbwa nekurapa inogona kushandiswa.Iyo yekurapa maitiro ndeyekuenderera kweiyo yakawanda polycondensation reaction uye kuumbwa kwechigadzirwa chikuru chekupedzisira.Iyi nzira yakasiyana nekunyunguduka uye kurapwa kwe general thermoplastic.Haigadziriswe, kusanganisira zvese zvemuviri nemakemikari maitiro.
PF inogona kuumbwa nejekiseni nenzira yakafanana neye thermoplastic.Pf inoshandiswa kuumba jekiseni inoda mvura yakanaka, kuumba pasi peyakaderera jekiseni kumanikidzwa, yakakwira yekupisa kuomarara uye nekukurumidza kuomesa kukurumidza, yakanaka kupenya pamusoro pezvikamu zvepurasitiki, kudhirowa kuri nyore uye pasina kusvibiswa kune mold.Zvisinei, jekiseni molding inewo zvikanganiso zvayo.Semuenzaniso, kunyunguduka kunogumira nemhando yekuzadza, haina kukodzera kuumba zvikamu zvepurasitiki nekuwedzera, uye nhamba huru yemagedhi uye nzira dzekuyerera mushure mekurapa haigone kudzokororwa uye inogona kuraswa chete.
Muchidimbu, thermoplastic PF inogona kugadzirwa neyakajairwa jekiseni rekugadzira muchina, asi mamiriro ekuita anofanirwa kudzorwa zvakanyanya.Thermosetting pf inofanirwa kugadzirwa nePF yakakosha jekiseni rekuumba muchina (mbiya uye screw zvakasiyana kubva kune wakajairwa jekiseni rekuumba muchina), uye mold inofanirawo kushandisa yakakosha dhizaini chimiro!
Sino Vision Vehicle & Service Co., Limited, iri muHuangyan Town, Taizhou, inotarisa pakugadzira jekiseni rekugadzira senge bakelite, BMC jekiseni rekuumba uye kunyatso gadzira jekiseni repurasitiki.Bakelite uye BMC jekiseni rekugadzira zvigadzirwa zvinoshandiswa zvakanyanya mumarudzi ese ekitchenware, electromechanical uye imba yekushandisa accessories.Iyo kambani ine yakasimba mainjiniya uye tekinoroji timu, iyo yakazvipira kugadzira zvigadzirwa zvine mhando yepamusoro uye yakanaka mutengo kune vatengi, iyo inogona kusangana neakasiyana ekugadzirisa zvinodiwa nevatengi.
