NaAndy anobva kuBaiyear fekitori
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 ndicho chinyorwa chekutanga.
(1).PS (polystyrene)
1. Kuita kwePS:
PS is amorphous polymer ine mvura yakanaka uye yakaderera kunyura kwemvura (pasi pe00.2%).Ipurasitiki inoonekera iri nyore kugadzira uye kugadzirisa.Zvigadzirwa zvaro zvine mwenje we88-92%, kusimba kwakasimba kwekuita uye kuoma kwakanyanya.Zvisinei, zvigadzirwa zve PS zvinoputika, zvinowanzoita kushushikana kwemukati, hazvina kusimba kupisa (60-80 ° C), hazvina chepfu, uye zvine giravhiti chaiyo inosvika 1.04g\cm3 (yakakura zvishoma pane mvura).
Molding shrinkage (ukoshi hunowanzo 0.004-0.007in/in), yakajeka PS - iri zita rinongoratidza pachena resin, kwete crystallinity.(Chemical and physical properties: MaPS mazhinji ekutengeserana anoonekera, amorphous zvinhu. PS ine yakanaka kwazvo geometric kugadzikana, thermal stability, optical transmission properties, magetsi insulating properties, uye katsika kadiki-diki kekutora unyoro. Inoshingirira kumvura, diluted inorganic acids , asi inogona kusvibiswa neakasimba oxidizing asidhi senge concentrated sulfuric acid, uye inogona kuzvimba nekuremara mune zvimwe organic solvents.)
2. Maitiro ePS:
Nzvimbo yakanyungudika yePS i166 ° C, tembiricha yekugadziridza inowanzoita 185-215 ° C, uye tembiricha yekunyunguduka i180 ~ 280 ° C.Pamidziyo inodzoreredza moto, muganho wepamusoro i250 ° C, uye tembiricha yekuora ingangoita 290 ° C, saka tembiricha yekugadziridza kwayo yakakura.
Iyo tembiricha yekuumbwa i40 ~ 50 ℃, iyo jekiseni pressure: 200 ~ 600bar, kumhanya kwejekiseni kunokurudzirwa kushandisa kukurumidza jekiseni kumhanya, uye vanomhanya nemagedhi vanogona kushandisa ese akajairwa marudzi emasuwo.Zvishandiso zvePS kazhinji hazvidi kuomeswa zvisati zvagadziriswa kunze kwekunge zvakachengetwa zvisina kunaka.Kana kuomeswa kuchidikanwa, iyo yakakurudzirwa kuomeswa mamiriro ndeye 80C kwe2 ~ 3 maawa.
Nekuda kwekudziya kwakadzikira kwePS, mamwe molds anogona kukurumidza kupfupikiswa uye kusimba kana agadzirwa kuti abvise kupisa.Mwero wekutonhora unokurumidza kupfuura wezvakajairwa zvigadzirwa, uye nguva yekuvhura mold inogona kunge iri pamberi.Nguva yeplasticizing uye nguva yekutonhora ipfupi, uye nguva yekuumba inozoderedzwa;kupenya kwezvigadzirwa zvePS kuri nani sezvo tembiricha ye mold inowedzera.
3.Typical applications: kurongedza zvigadzirwa (midziyo, zvivharo, mabhodhoro), zvinoraswa zvekurapa, matoyi, makapu, mapanga, tape reels, dutu mahwindo uye akawanda efoam zvigadzirwa - mazai makatoni.Nyama nehuku yekurongedzera matireyi, mabhodhoro mavara uye akafurwa nePS cushioning zvinhu, chigadzirwa kurongedza, zvinhu zvemumba (chekuchekwa, matireyi, nezvimwewo), magetsi (midziyo inoonekera, mwenje diffuser, insulating mafirimu, nezvimwewo).
(2).HIPS (modified polystyrene)
1. Kuita kweHIPS:
HIPS chinhu chakagadziridzwa chePS.Iyo ine 5-15% yerubha chikamu mumorekuru.Kuomarara kwayo kunosvika kana kana kupfuura kwePS, uye simba rayo rekuita rinovandudzwa zvakanyanya (yakanyanya kukanganisa polystyrene).Iine flame retardant giredhi uye stress crack resistance.magiredhi, magiredhi egirosi akakwira, magiredhi esimba akanyanya kukwirisa, magiredhi egirazi akasimbisa mamakisi, uye magiredhi akasara akaderera.
Zvimwe zvakakosha zvimiro zveHIPS yakajairwa: kubhenda simba 13.8-55.1MPa;tensile simba 13.8-41.4MPa;elongation panguva yekuzorora 15-75%;density 1.035-1.04 g/ml;Zvakanakira.Zvinyorwa zveHIPS hazvina kujeka.HIPS ine mvura yakaderera kunyura uye inogona kugadziriswa pasina pre-yaoma.
2. Maitiro maitiro eHIPS:
Nekuti iyo molecule yeHIPS ine 5-15% rabha, iyo inokanganisa kuyerera kwayo kusvika pamwero wakati, kudzvanywa kwejekiseni uye tembiricha yekuumba inofanira kunge yakakwira.Chiyero chayo chekutonhora chinononoka kupfuura chePS, saka zvakakwana kubata kumanikidza, kubata nguva uye nguva yekutonhora inodiwa.Kutenderera kunenge kwakareba zvishoma kupfuura kwePS, uye tembiricha yekugadzira inowanzo 190-240 ° C.
HIPS resin inotora unyoro zvishoma nezvishoma, saka kuomesa kazhinji hakudiwi.Dzimwe nguva hunyoro hwakanyanya pamusoro pezvinhu zvinogona kutorwa, zvichikanganisa kutaridzika kwechigadzirwa chekupedzisira.Hunyoro hwakawandisa hunogona kubviswa nekuomesa pa 160 ° F kwemaawa maviri-3.Pane dambudziko rakakosha re "white edge" muzvikamu zveHIPS, izvo zvinogona kuvandudzwa nekuwedzera tembiricha ye mold uye clamping simba, kuderedza kudzvanywa kwekubata uye nguva, nezvimwewo, uye maitiro emvura muchigadzirwa achave akajeka.
4.Nzvimbo dzekushandisa: Nzvimbo huru dzekushandisa ndeyekurongedza uye zvinoraswa, zviridzwa, midziyo yemumba, matoyi uye zvigadzirwa zvekuvaraidza, uye indasitiri yekuvaka.Flame retardant giredhi (UL V-0 uye UL 5-V), inopesana ne polystyrene yakagadzirwa uye inoshandiswa zvakanyanya muTV casings, bhizinesi michina uye zvigadzirwa zvemagetsi.
Kuenderera mberi, kana uchida kuziva zvakawanda, ndapota inzwa wakasununguka kutibata nesu.Baiyear ifekitari yakakura yakazara yakazara inobatanidza kugadzira epurasitiki mold, jekiseni rekugadzira uye sheet simbi kugadzirisa.Kana kuti iwe unogona kuramba uchiteerera kune nzvimbo yenhau yewebhusaiti yedu yepamutemo: www.baidasy.com, isu ticharamba tichivandudza ruzivo rwenhau dzine chekuita nejekiseni molding processing industry.
