Yakadzorerwa November 2, 2022
Heino nzvimbo yenhau yeBaiyear's injection molding industry.Tevere, Baiyear ichakamura jekiseni rekuumba kuita zvinyorwa zvakati wandei kusuma ongororo yezvakagadzirwa zvejekiseni rekuumba maitiro, nekuti kune zvakawanda zvirimo.Chinotevera chinyorwa chechitanhatu.
(14).PPO (polyphenylene ether)
1. Kuita kwePPO
Polyphenylene oxide is poly-2,6-dimethyl-1,4-phenylene oxide, inozivikanwawo sepolyphenylene oxide, zita rechirungu Polyphenyleneoxiole (inonzi PPO), yakagadziridzwa polyphenylene ether inogadziriswa nepolystyrene kana mamwe mapolima.Zvepabonde polyphenylene ether, inonzi MPPO.
PPO (NORLY) ipurasitiki yeinjiniya ine zvivakwa zvakanakisa.Iine kuomarara kwepamusoro kupfuura PA, POM nePC, kusimba kwemagetsi, kusimba kwakanaka, kupisa kwakanaka kwekudzivirira (thermal deformation tembiricha i126 ℃), uye yakakwirira dimensional kugadzikana (shrinkage tembiricha).chiyero che0.6%), kunyura kwemvura yakaderera (pasi pe0.1%).Izvo zvisingabatsiri ndezvokuti hazvina kugadzikana kune ultraviolet rays, mutengo wakakwirira, uye dosage idiki.
PPO haina muchetura, inoonekera, ine yakaderera hama density, uye ine yakanakisa mechaniki simba, kusagadzikana kuzorora kuramba, creep resistance, kupisa kupisa, kuramba mvura, uye mhute yemvura.Zvakanaka zvemagetsi zvivakwa munzvimbo dzakasiyana siyana tembiricha uye frequency kusiyanisa, hapana hydrolysis, diki kuumba shrinkage, murazvo unodzosa uye unodzima wega, kushomeka kuramba kune inorganic acids, alkalis, anonhuwirira hydrocarbons, halogenated hydrocarbons, oiri, nezvimwewo, zviri nyore kuzvimba Kana kushushikana kwekushushikana, izvo zvakanyanya kukanganisa kunyungudika kunyungudika, kuoma kwekugadzirisa uye kuumba, mazhinji ezvishandiso zvinoshanda MPPO (PPO blends kana alloys), senge PS shanduko yePPO, inogona kuvandudza zvakanyanya mashandiro ekugadzirisa, kuvandudza kushushikana kwekuputika kuramba uye kukanganisa. kupikisa Kuita, kuderedzwa kwemutengo, kungodzikisira kushoma mukupisa kupisa uye gloss.
Mapolymers akagadziridzwa anosanganisira PS (kusanganisira HIPS), PA, PTFE, PBT, PPS uye akasiyana elastomers, polysiloxane, PS yakagadziridzwa PPO parafini, chikuru chigadzirwa, MPPO ndiyo inonyanya kushandiswa injiniya epurasitiki alloy akasiyana.Iwo makuru emhando dzeMPPO iPPO/PS, PPO/PA/elastomers uye PPO/PBT elastomer alloys.
2. Maitiro ePPO maitiro:
PPO ine yakakwira melt viscosity, kushata kwemvura, uye yakakwirira kugadzirisa mamiriro.Isati yagadziriswa, inoda kuomeswa patembiricha ye100-120 ° C kwemaawa 1-2, tembiricha yekuumba iri 270-320 ° C, uye tembiricha yekuumbwa inonyatso kudzorwa pa75-95 ° C.processing.Mukugadzirwa kweiyi plastiki doro repurasitiki, jet flow pattern (serpentine pattern) iri nyore kugadzirwa pamberi penozzle, uye nzira yekuyerera yenozzle inonyanya kukura.
Ukobvu hudiki hunobva pa0.060 kusvika 0.125 inches yekuumbwa kwakajairwa uye 0.125 kusvika 0.250 inches yemafuro ezvimiro, uye kupisa kunobva paUL94 HB kuenda kuVO.
3.Typical application range:
PPO neMPPO inogona kugadziriswa nenzira dzakasiyana-siyana dzekugadzirisa senge jekiseni rekugadzira, extrusion, kuvhuvhuta, kuumba, kupupa furo uye electroplating, vacuum coating, kudhinda muchina kugadzirisa, nezvimwewo, nekuda kwekunyanya kunyunguduka viscosity uye yakanyanya kupisa tembiricha.
PPO neMPPO zvinonyanya kushandiswa mumidziyo yemagetsi, mota, midziyo yemumba, midziyo yemuhofisi nemichina yemaindasitiri, nezvimwewo, vachishandisa MPPO yekudzivirira kupisa, kupikisa kupikisa, kugadzikana kwedimensional, kukwenya kuramba, uye kupenengura kuramba;
Paintability uye zvinhu zvemagetsi: anoshandiswa kugadzira madhibhodhi emotokari, magidhidhiyadhiya, maspeaker grilles, maconsoles, fuse boxes, relay boxes, connectors, wheel covers;inoshandiswa zvakanyanya muindasitiri yemagetsi neyemagetsi kugadzira zvinobatanidza, coil windings Spools, switching relays, tuning midziyo, hombe dzemagetsi kuratidza, variable capacitor, bhatiri accessories, maikorofoni nezvimwe zvinhu.
Midziyo yemumba inoshandiswa paterevhizheni, makamera, matepi evhidhiyo, matepi rekodha, maair conditioner, heaters, rice cooker nezvimwe zvikamu.Inogona kushandiswa sezvikamu zvekunze uye zvikamu zvemakopi, makombiyuta maitiro, printers, fax machines, etc. Mukuwedzera, inogona kushandiswa sekhamera, timer, pombi yemvura, blower shell uye zvikamu, silent gear, pipeline, valve body, chiridzwa chekuvhiya, sterilizer uye zvimwe zvikamu zvemidziyo yekurapa.
Yakakura-yakakura kuvhuvhuta inogona kushandiswa kune yakakura-yakakura zvikamu zvemotokari senge vaparadzi, mabumpers, uye yakaderera-inopupuma.Inokodzera kugadzirwa kwezvigadzirwa zvakakura zvine kusimba kwepamusoro, kugadzikana kwedimensional, kupfava kwakanaka kwenzwi, uye yakaoma yemukati zvimiro, seyakasiyana siyana mabhomba, zvigadziko, zvemukati Iyo bracket uye dhizaini zvine rusununguko rwakakura, uye chigadzirwa hachina uremu.
(15).PBT polybutylene terephthalate
1. Kuita kwePBT:
PBT ndeimwe yeakaomesesa engineering thermoplastics.Iyo semi-crystalline zvinhu zvine yakanaka kwazvo kugadzikana kwemakemikari, simba remagetsi, magetsi ekudzivirira emagetsi uye kugadzikana kwekupisa.Zvinhu izvi zvine kugadzikana kwakanaka mune dzakasiyana siyana mamiriro ezvakatipoteredza, uye PBT ine isina kusimba hygroscopic zvivakwa.Kusimba kwekusimba kwePBT isina kusimbiswa i50MPa, uye kusimba kwegirazi rekuwedzera mhando PBT i170MPa.Yakawandisa girazi yekuwedzera inokonzeresa kuti zvinhu zvive brittle.
PBT;crystallization inokurumidza kwazvo, izvo zvinokonzeresa kubhenda deformation nekuda kwekutonhora kusina kuenzana.Kune zvemidziyo zvine magirazi ekuwedzera, iyo shrinkage munzira yemaitiro inogona kuderedzwa, asi iyo shrinkage mugwara perpendicular kune maitiro akanyanya kufanana neakajairika zvinhu.
The general material shrinkage rate iri pakati pe1.5% ne2.8%.Zvishandiso zvine 30% magirazi ekuwedzera anoderera pakati pe0.3% ne1.6%.Melting point (225% ℃) uye yakanyanya tembiricha deformation tembiricha yakaderera pane PET zvinhu.The Vicat softening tembiricha inenge 170°C.Tembiricha yekuchinja kwegirazi (girazi trasitiotemperature) iri pakati pe22°C kusvika 43°C.
Nekuda kweiyo yakakwira crystallization rate yePBT, viscosity yayo yakadzikira, uye nguva yekutenderera yezvikamu zvepurasitiki kugadzirisa kazhinji yakaderera.
2. Maitiro ePBT maitiro:
Kuomesa: Ichi chinhu chiri nyore hydrolyzed pakupisa kwakanyanya, saka kuomeswa kusati kwagadziriswa kwakakosha.Inokurudzirwa kuomesa mamiriro mumhepo ndeye 120C kwe6 ~ 8 maawa, kana 150C kwe2 ~ 4 maawa.
Humidity inofanira kunge iri pasi pe0.03%.Kana kuomeswa ne hygroscopic desiccator, mamiriro akakurudzirwa ari 150 ° C kwemaawa 2.5.Tembiricha yekugadziridza i225 ~ 275 ℃, uye tembiricha inokurudzirwa i250 ℃.Kune iyo isina kusimbiswa, tembiricha yekuumbwa i40 ~ 60 ℃.Iyo yekutonhodza chiteshi che mold inofanira kunyatsogadzirirwa kudzikisa kukotama kwechikamu chepurasitiki.Kupisa kwekupisa kunofanirwa kuve nekukurumidza uye kwakaenzana.
Iyo dhayamita yakakurudzirwa ye mold yekutonhora chiteshi ndeye 12mm.Kudzvanywa kwejekiseni kuri pakati nepakati (kusvika 1500bar), uye kumhanya kwejekiseni kunofanirwa kunge kuri kukurumidza sezvinobvira (nekuti PBT inosimba nekukurumidza).Mumhanyi uye gedhi: Inokurudzirwa kushandisa denderedzwa mumhanyi kuti uwedzere kutapurirana kwekumanikidza (chiitiko formula: mumhanyi dhayamita = epurasitiki chikamu ukobvu + 1.5mm).
Mhando dzakasiyana-siyana dzemagedhi dzinogona kushandiswa.Vanopisa vanomhanya vanogona zvakare kushandiswa, asi kutarisirwa kunofanira kutorwa kudzivirira kuvuza uye kushatisa kwezvinhu.Iyo dhayamita yegedhi inofanirwa kunge iri pakati pe 0.8 ~ 1.0 * t, uko t ndiko ukobvu hwechikamu chepurasitiki.Kana iri gedhi rakanyura mumvura, dhayamita shoma ye 0.75mm inokurudzirwa.
3.Typical application range:
midziyo yemumba (chikafu chekugadzira mashizha, vacuum cleaner components, magetsi mafeni, hair dryer housings, midziyo yekofi, nezvimwewo), zvinhu zvemagetsi (switch, motor housings, fuse boxs, computer keyboard keys, etc.), mota Industrial (radiator grilles, mapaneru emuviri, zvivharo zvemavhiri, gonhi uye zvikamu zvehwindo, nezvimwe.
Saka ruzivo rwakawanda rwakaunzwa munzvimbo iyi.Kuti uwane rumwe ruzivo, Baiyear ichaigadzirisa nekukurumidza sezvinobvira.Isu tichagara tichigadziridza epurasitiki zvigadzirwa, jekiseni kuumba kugadzirwa, jekiseni rekuumba midziyo yekusuma, mold dhizaini, mold kuveza, mold kugadzira michina sumo, sheet simbi kugadzirisa, Ruzivo rwekugovera bhokisi kugadzirwa, simbi bhokisi kugadzira, sheet simbi yekugadzira michina sumo, isina mvura. junction box, waterproof window cover, etc. Kana iwe uchifarira ruzivo rwuri pamusoro apa, unogona kundibata chero nguva, ndichafara kukushandira uye kutarisira kusvika kwako.
