Mold tembiricha: 37~93℃.
Kemikari uye midziyo yemuviri PC/PBT ine zvinhu zvakasanganiswa zvePC nePBT, senge kusimba kwepamusoro uye kugadzikana kwejometri yePC uye kugadzikana kwemakemikari, kugadzikana kwekupisa uye lubrication zvimiro zvePBT.
Mashandisirwo akajairika: midziyo yefiriji, midziyo yekuchengetera, imba yekubikira, yekuisa chisimbiso, nezvimwe.
Injection molding process conditions.
Kuomesa: Hapana chikonzero chekuomesa kana chakachengetedzwa zvakanaka.
Kunyunguduka tembiricha: 220 kusvika 260°C.Pamidziyo ine mamorekuru akakura, tembiricha yakakurudzirwa yekunyunguduka iri pakati pe200 ne250°C.
Mold tembiricha: 50-95°C.Kupisa kwepamusoro kweforoma kunofanirwa kushandiswa kumadziro emadziro ari pasi pe6mm uye yakadzika mold tembiricha yemadziro ukobvu pamusoro pe6mm.Kutonhora kwekutonhora kwezvikamu zvepurasitiki kunofanira kunge kwakafanana kuderedza mutsauko wekuderera.Kuti uwane nguva yakakwana yekutenderera, dhayamita yekutonhodza yegomba haifanire kunge isingasviki 8mm uye chinhambwe kubva panzvimbo yekuumbwa chinofanira kunge chiri mukati me1.3d (apo "d" iri dhayamita yegomba rekutonhodza).
Injection pressure: 700 kusvika 1050 bar.
Injection speed: High speed jekiseni inokurudzirwa.Vanomhanya nemasuwo: Chidhaya chemumhanyi chinofanira kuva pakati pe4 ne7.5 mm uye urefu hwemumhanyi hunofanira kuva hupfupi sezvinobvira.Mhando dzakasiyana dzemagedhi dzinogona kushandiswa uye kureba kwegedhi hakufanirwe kudarika 0.75mm.kunyanya yakakodzera kushandisa inopisa mumhanyi molds.
Kemikari uye zvimiro zvemuviri: Iyo yakakwira crystallinity yePE-HD inokonzeresa kuwanda kwepamusoro, kusimba kwesimba, tembiricha yekushatisa tembiricha, viscosity uye kugadzikana kwemakemikari.PE-HD ine yakakwirira kuramba kupindirana kupfuura PE-LD.PE-HD ine simba rekuita rakaderera.Izvo zvimiro zvePH-HD zvinonyanya kudzorwa nedensity uye molecular uremu kugovera.Iyo molecular huremu kugovera kwePE-HD yakakodzera kuumbwa kwejekiseni yakatetepa.Nokuda kwehuwandu hwe 0.91-0.925g / cm3, tinoitumidza kuti rudzi rwekutanga rwePE-HD;nokuda kwehuwandu hwe0.926-0.94g / cm3, inonzi yechipiri rudzi rwePE-HD;nokuda kwehuwandu hwe 0.94-0.965g / cm3, inonzi rudzi rwechitatu rwePE-HD.-Nyaya yacho ine maitiro akanaka ekuyerera, ine MFR pakati pe 0.1 ne 28. Iyo yakakwirira ye molecular uremu, hurombo hunoyerera hutsika hwePH-LD, asi ine simba rekuita zviri nani.PE-LD is a semi-crystalline material ine high shrinkage. mushure mekuumbwa, pakati pe1.5% ne4%.PE-HD inotapukirwa nekupwanya kwekushushikana kwezvakatipoteredza.PE-HD inonyungudika zviri nyore mumahydrocarbon solvents patembiricha iri pamusoro pe60C, asi kuramba kwayo kunyungudika kwakati nani pane kuya kwePE-LD.
4.PE-LD
Kuomesa: kazhinji hazvidiwi
Kunyunguduka tembiricha: 180~280℃
Mold tembiricha: 20~40 ℃ Kuti uwane kutonhora kwakafanana uye kuwedzera kwehupfumi kudziyisa, zvinokurudzirwa kuti dhayamita yegomba inotonhorera inofanira kunge iine 8mm uye chinhambwe kubva painotonhora kuenda kunzvimbo yekuumbwa haifanire kudarika 1.5 nguva dze iyo dhayamita yemhango inotonhorera.
Jekiseni pressure: kusvika 1500 bar.
Kubata kumanikidza: kusvika ku750 bar.
Injection kumhanya: Kukurumidza jekiseni kumhanya kunokurudzirwa.
Vanomhanya uye magedhi: Mhando dzakasiyana dzevamhanyi uye magedhi anogona kushandiswa PE inonyanya kukodzera kushandiswa neanopisa mumhanyi molds.
Kemikari uye zvinhu zvemuviri: Kuwanda kwePE-LD zvinhu zvekutengesa kushandiswa ndeye 0.91 kusvika 0.94 g / cm3.PE-LD inopindira kune gasi uye mhute yemvura. Iyo yakakwirira coefficient yekuwedzera kwekupisa kwePE-LD haina kukodzera kugadzirisa zvigadzirwa. kushandiswa kwenguva refu.Kana iyo density yePE-LD iri pakati pe0.91 ne0.925g/cm3, ipapo shrinkage rate iri pakati pe2% ne5%;kana density iri pakati pe0.926 ne0.94g/cm3, ipapo shrinkage rate iri pakati pe1.5% ne4%.Iyo chaiyo ikozvino shrinkage inoenderanawo nejekiseni molding process paramita.PE-LD inoshingirira kune zvinonyungudutsa zvakawanda patembiricha yekamuri, asi zvinonhuhwirira uye zvine chlorinated hydrocarbon zvinonyungudutsa zvinogona kukonzera kuzvimba.Zvakafanana nePE-HD, PE-LD inotapukirwa nekupwanya kwekushushikana kwezvakatipoteredza.
