Biodegradable Injection Molding Modified Material
Nzira dzinoverengeka dzemaindasitiri dzinokwanisa kushandiswa (kureva kuti yakakwira molecular uremu) PLA. Maviri makuru monomers anoshandiswa: lactic acid, uye cyclic di-ester, lactide. Nzira yakajairika yekuenda kuPLA ndeye ring-kuvhura polymerization yelactide ine akasiyana simbi catalysts (kazhinji tin octoate) mumhinduro kana sekumiswa. Iyo metal-catalyzed reaction inowanzokonzera racemization yePLA, ichideredza stereoregularity yayo kana ichienzaniswa nekutanga zvinhu (kazhinji chibage starch).
PLA inonyungudika mune dzakasiyana siyana organic solvents. Ethyl acetate, nekuda kwekureruka kwayo kwekuwana uye yakaderera njodzi yekushandisa, inonyanya kufarira. PLA 3D printa filament inonyungudika kana yakanyikwa mu ethyl acetate, zvichiita kuti ive inonyungudutsa inobatsira yekuchenesa 3D inodhinda extruder misoro kana kubvisa PLA zvinotsigira. Iyo yekubikira ye ethyl acetate yakadzikira zvekugonesawo PLA mukamuri yemhute, yakafanana nekushandisa acetone vapor kutsvedzerera ABS.
Zvimwe zvinonyungudutsa zvakachengeteka zvekushandisa zvinosanganisira propylene carbonate, iyo yakachengeteka kudarika ethyl acetate asi yakaoma kutenga mune zvekutengesa. Pyridine inogonawo kushandiswa asi iyi haina kuchengeteka kudarika ethyl acetate uye propylene carbonate. Iinewo kunhuhwirira kwakashata kwehove.
SPLA Injection Molding Features
Izvo zvakakosha zvechigadzirwa iPLA, PBAT uye inorganic Rudzi urwu rwechigadzirwa rune kunyungudika kwakanaka uye kusimba kwemagetsi, uye inonyanya kukodzera jekiseni molding. Inogona kuburitsa akawanda-cavity zvigadzirwa nenguva pfupi yekutonhodza, yakaderera mutengo, uye nekukurumidza kushatisa. Chigadzirwa chacho chine zvakanaka kugadzirisa uye hunhu hwemuviri, uye chinogona kushandiswa zvakananga kuumba jekiseni kugadzira zvigadzirwa zvakasiyana-siyana.
SPLA Injection Molding Application Field
Kusimba kwepamusoro, simba rakakwirira 3D kudhinda kwakagadziridzwa zvinhu,
Yakaderera-inodhura, yakakwirira-yakasimba 3D kudhinda yakagadziridzwa zvinhu
