1. Kurapa kwepurasitiki
Nekuti PET macromolecules ane lipid mapoka uye ane mamwe hydrophilic zvimiro, tsanga inonzwa kumvura pakupisa kwakanyanya.Kana iyo yemukati memvura yadarika muganho, iyo PET molecular huremu inodzikira mukugadzirisa, uye zvigadzirwa zvinova ruvara uye brittle.
Nokudaro, isati yagadziriswa, zvinhu zvinofanira kuomeswa, nekupisa kwekuoma kwe150 ℃, kupfuura maawa mana;kazhinji 170 ℃, 3-4 maawa.Mhepo nzira inogona kushandiswa kuedza kuomeswa zvakakwana.Iyo chikamu chePET bhodhoro billet recycling zvinhu hazvifanirwe kudarika 25%, uye zvinhu zvakadzokororwa zvinofanirwa kunyatso kuomeswa.
2. Kusarudzwa kwejekiseni molding machine
Nekuti PET ine nguva pfupi yakagadzikana mushure mekunyungudika uye yakakwira kunyungudika, zvinodikanwa kuti usarudze iyo jekiseni system ine mamwe tembiricha ekudzora zvikamu uye kushoma kuzvidzora uye kupisa chizvarwa panguva yepurasitiki, uye huremu chaihwo hwechigadzirwa (kusanganisira. mvura yekudyara zvinhu) haifanire kunge iri pasi pe2/3 yehuwandu hwejekiseni yemuchina.
3. Mold uye kudurura gedhi dhizaini
PET bhodhoro embryo, rinowanzo umbwa nekupisa kuyerera chiteshi mold, mold uye jekiseni rekugadzira muchina template pakati pezviri nani kuve neaya yekupisa yekupisa, ukobvu hwayo hunosvika 12mm, uye ndiro yekupisa yekupisa inofanirwa kukwanisa kushingirira.Exhaust inofanirwa kukwana kudzivirira kupisa kwenzvimbo kana kupatsanuka, asi kudzika kwechiteshi chekuburitsa kazhinji hakupfuure 0.03mm, zvikasadaro zviri nyore kugadzira divi rinobhururuka.
4. Nyunguduka tembiricha
Inowanikwa mhepo-emission nzira kuyerwa, 270-295 ℃ renji, yakagadziridzwa giredhi GF-PET inogona kusetwa ku290-315 ℃, nezvimwe.
5. Kumhanya kwejekiseni
Iyo general jekiseni kumhanya kunofanirwa kukurumidza kudzivirira nguva isati yakwana coagulation panguva yejekiseni.Asi nekukasira, shear rate yakakwira, ita kuti zvinhu zvive zvisina kusimba.Kupfura kunowanzopedzwa mumasekonzi mana.
6. Back pressure
Iyo yakaderera zviri nani, kudzivirira kupfeka.Kazhinji isingapfuure 100bar, kazhinji isinga shandiswe.
7. Nguva yekugara
Usashandise nguva yakareba yekuchengeta kudzivirira kudonha kwema molecular uremu, uye edza kudzivirira tembiricha iri pamusoro pe300 ℃.Kana iyo shutdown isingasviki maminetsi gumi nemashanu, ita chete kurapwa kwekupfura mhepo;kana anopfuura maminetsi gumi nemashanu, wobva wachenesa ne viscosity PE, uye udonhedze tembiricha yehumburumbira kune tembiricha yePE, kusvika pakatangazve.
8. Chengetedzo
Kudzokorodza zvinhu hazvigone kuve zvakakura zvakanyanya, zvikasadaro, zviri nyore kugadzira mune "bhiriji" uye kukanganisa plasticizing;
Kana iyo mold tembiricha kutonga haina kunaka, kana zvinhu tembiricha kutonga hazvina kukodzera, zviri nyore kugadzira "white fog" uye opaque;iyo mold tembiricha yakaderera uye yunifomu, nekukurumidza kutonhora kumhanya, kushoma crystallization, ipapo chigadzirwa chiri pachena.
Huangyan Leiao Molding Co., Ltd. iri muguta reHuangyan District mold, Taizhou, mudunhu reTaizhou, rinova "guta rekumusha kweChinese mold".Iyo kambani inonyanya kuita mukugadzira jekiseni mold, ine makore mazhinji ehunyanzvi hwekugadzira mold, kunyanya kugadzira nekugadzirisa bhodhoro embryo mold, PET commodity mold, bhodhoro cap mold, mukati memota uye kunze kwekushongedza mold… … mold system ine yayo yakasarudzika dhizaini uye kugadzirisa tekinoroji, zvichibva pane iyo pfungwa ye "Kutendeseka manejimendi", ine vatengi vekumba nevekunze kuti vagadzire hukama hwenguva refu hwekubatana, ndinotenda kuti Leiao achave akakodzera kuvimba newe mumubatanidzwa. enterprise.
