3,Nylon(PA). Ipurasitiki yeinjiniya, ipurasitiki inoumbwa ne polyamide resin, inonzi PA. pane PA6 PA66 PA610 PA1010, nezvimwewo. Zvimiro zvenaironi ndizvo zvinotevera.
a, naironi ine yakakwira crystallinity, yakakwira mechanical simba, yakanaka kusimba, yakakwirira tensile, compression simba.
b, kwakatanhamara kuneta kuramba, kupfeka kuramba, corrosion resistance, heat resistance, non-chepfu, yakanakisa magetsi zvinhu.
c
4,Polyformaldehyde (POM). Iyo inozivikanwawo semujaho wesimbi zvinhu, imhando yeinjiniya epurasitiki. Zvinhu uye kushandiswa kwepolyformaldehyde
a, paraformaldehyde ine yakanyanya crystalline chimiro, ine yakanakisa michina zvimiro, yakakwira modulus yekunyungudika, kusimba uye kuoma kwepasi zvakare yakakwira zvakanyanya, inozivikanwa se "simbi mukwikwidzi"
b. Diki coefficient of friction, yakanakisa kupfeka kuramba uye kuzvizora, yechipiri chete kune naironi, asi yakachipa kupfuura naironi.
c, yakanaka solvent kuramba, kunyanya organic solvents, asi kwete yakasimba asidhi, alkali yakasimba uye oxidizers.
d, yakanaka dimensional kugadzikana, inogona kugadzira chaiyo zvikamu
e, kuumba shrinkage, kugadzikana kwekupisa kwakashata, kupisa kuri nyore kuora
5,Acrylonitrile-butadiene-styrene (ABS). Plastiki yeABS ndeyepamusoro-simba yakagadziridzwa polystyrene, inoumbwa neacrylonitrile, butadiene uye styrene mune imwe reshiyo yemakomponi matatu, ine chiedza chenzou, opaque, isiri-chepfu uye isina kunaka.
Hunhu uye Mashandisirwo
a. High mechanical simba; simba rinopikisa kuramba; zvakanaka zvinokambaira kuramba; yakaoma, yakaoma, yakaoma, nezvimwewo.
b, Iyo yepamusoro yezvikamu zvepurasitiki zveABS zvinogona kuiswa
c, ABS inogona kusanganiswa nemamwe mapurasitiki uye rabha kuti ivandudze kuita kwayo, senge (ABS + PC)
6, Polycarbonate (PC). Inowanzozivikanwa segirazi rinodzivirira bara, chinhu chisina chepfu, chisina kunaka, chisina kunhuwa, chakajeka, chinopisa, asi chinogona kuzvidzima chega mushure mekubva mumoto. Hunhu uye kushandiswa.
a. Nekuoma kwakakosha uye kuoma, ine yakanyanya kunaka simba rekuita pakati pezvese thermoplastic zvinhu
b. Yakanakisa inokambaira kuramba, yakanaka dimensional kugadzikana, yakakwirira kuumba kurongeka; zvakanaka kupisa kupisa (120 degrees)
c. Izvo zvisingabatsiri isimba rakaderera kuneta, kushushikana kwakanyanya kwemukati, nyore kutsemuka, uye kushomeka kusakara kwezvikamu zvepurasitiki.
7,PC+ABS chiwanikwa (PC+ABS). Yakasanganiswa PC (engineering mapurasitiki) uye ABS (general-chinangwa mapurasitiki) zvakanakira zvese zviri zviviri, zvakavandudza mashandiro ezvose zviri zviviri. Iine ABS uye PC makemikari kuumbwa, ine ABS yakanaka fluidity uye molding processability, PC kukanganisa kuramba uye kuramba kupisa uye kutonhora kutenderera shanduko. Features
a. Inogona kupihwa neglue muromo / hombe yemvura muromo mold dhizaini.
b, Surface inogona kupfapfaidzwa mafuta, plating, simbi pfapfaidzo firimu.
c. Cherechedza kuwedzera kwepamusoro pemhepo.
d. Izvo zvinhu zvinowanzo shandiswa mukupisa mumhanyi mold uye zvakashandiswa mune zvakawanda uye zvevatengi zvekukurukurirana zvigadzirwa, senge mbozhanhare kesi / makomputa kesi.
