Vagadziri vanoona shanduko huru muna 2025 nePE PP jekiseni rekuumba screw barrel. Ichi chishandiso kubvaInjection Screw Factoryinoita kuti zvinhu zvifambe zvakanaka mukatiInjection Molding Barrel. TheJekiseni Machine Screwinobatsira kudzora kudzvanywa uye tembiricha. Aya magadzirirwo anobatsira kugadzira zvigadzirwa zvakasimba, zvemhando yepamusoro zvisina tsvina shoma.
Zvakajairwa Kukanganisa muPE PP Injection Molding
Warping uye Shrinkage
Warping uye shrinkage zvinowanzonetsa vagadziri vanoshanda nePE nePP. Kukanganisika uku kunoita kuti zvikamu zvimonya kana kushandura chimiro mushure mekutonhora. Pane zvinhu zvakati wandei zvinoita, serudzi rwezvinhu, kuti mold inotonhora sei, uye tembiricha panguva yekunyunguduka. Semuyenzaniso, zvinhu zvine akakwira shrinkage coefficients anowanzo kutenderera zvakanyanya. Lower crystallinity inobatsira kuderedza shrinkage. Fusion tembiricha,kutonhora chiteshi tembiricha, uye nguva yekutonhora inonyanya kukosha kune warpage. Packing pressure inova yakakosha kana uchishandisa zvinhu zvakadzokororwa. Zvidzidzo zvinoratidza kuti tembiricha yekunyunguduka, kubata nguva, uye nguva yejekiseni zvese zvinokanganisa kuti chikamu chinodzikira kana kuputika.
- Shrinkage uye warpage inowedzera nepamusoro crystallinity.
- Kutonhodza mwero uye tembiricha yekuumbwa kunogona kukonzera kusaenzana shrinkage.
- Zvikamu zvakakura zvakaumbwa zvinogara zvichiratidza imwe warpage nekuda kwekupisa kwekupisa.
Kuzadza Kusina Kukwana
Kuzadza kusina kukwana kunoitika kana purasitiki yakanyungudutswa isingazadze mold zvachose. Izvi zvinosiya mikaha kana zvikamu zvisipo muchigadzirwa chekupedzisira. Mold tembiricha, kudzvanywa kwejekiseni, uye nguva yekutonhora zvese zvinopesvedzera chikanganiso ichi. Kana kudzvinyirirwa kwakanyanyisa kana kuti zvinhu zvinotonhora nokukurumidza, plastiki haigoni kusvika kumakona ose e mold. Kurebesa nhanho dzekubata kunobatsira kuderedza mapeji uye kunatsiridza kufanana.
Surface Imperfections
Kusakwana kwepamusoro kunosanganisira zvigamba zvakakasharara, mavara ekuyerera, kana mitsetse inooneka pachigadzirwa. Izvi zvinokanganisa zvinowanzokonzerwa nekuyerera kusina kugadzikana panguva yejekiseni. Vatsvaguri vakashandisa macheki ekuona, ma microscopes, uye maikorosikopu erekitironi kuti vaone nyaya idzi. Vakaona kuti kushata kwepamusoro kunobatanidza zvakanyanya nemafambiro anoita zvinhu uye kukweshana mukati me mold. Kana kuyerera kukava kusagadzikana, kuremara kwepamusoro kunoonekwa kakawanda.
Zano: Kuchengeta kuyerera kwakadzikama uye mold pakudziya kwayo kunobatsira kudzivirira kusakwana kwepamusoro.
Kuparara Kwezvinhu
Material degradation zvinoreva kuti plastiki inotanga kuparara panguva yekuumbwa. Izvi zvinogona kuderedza simba uye kunaka kwechigadzirwa. Kune polypropylene, masayendisiti anoyera kuderedzwa nekutarisa kuti yakawanda sei iyo viscosity inodonha. Tembiricha yakanyanya, kukurumidza screw kumhanya, uye nguva refu mubhodho inomhanyisa maitiro aya. Akasiyana PP mamakisi anodzikisira pamitengo yakasiyana. Zvishandiso senge inline Raman spectroscopy uye rheological bvunzo zvinobatsira kuteedzera shanduko idzi munguva chaiyo.

| Kuyera Nzira | Rheological kuongororwa mu coaxial cylinder system; inline Raman spectroscopy yechokwadi-nguva PP kushatisa kuyerwa |
| Kuzvibata | Akasiyana PP mamakisi anoratidza akasiyana degradation mitengo; kurodha kwakaderera kunokonzera kuderera kunononoka, kurodha kwakanyanya kunokonzera kukurumidza viscosity kuderera |
Sei PE PP Jekiseni Kuumba Screw Barrel Inogadzirisa Kukanganisa
Yakagadziridzwa Screw Dhizaini yeUniform Melting
Iyo screw yakagadzirwa zvakanaka inoita mutsauko mukuru mukuumbwa kwejekiseni. Iyo PE PP jekiseni rekuumba screw barrel inoshandisa yakagadziridzwa screw chimiro chinobatsira kunyungudutsa plastiki zvakaenzana. Mainjiniya akaedza masiruu akasiyana, senge-matatu-zone screws uye yakakosha kusanganisa zvikamu, kuti vawane nzira yakanakisa yekupisa nekusanganisa zvinhu. Ivo vanoshandisa maturusi epamusoro kuyera kuti screw inonyungudutsa sei plastiki. Kana iyo screw dhizaini yakanyatso kurongeka, purasitiki yakanyungudutswa inoyerera zvakanaka uye inosvika tembiricha yakafanana kwese kwese.
- Kunyunguduka kwakafanana kunoreva nzvimbo shoma dzinotonhora uye pasina purasitiki isina kunyunguduka muchigadzirwa chekupedzisira.
- Kusanganisa screws kunobatsira kuchengetedza ruvara uye ukobvu hwepurasitiki yakanyungudutswa zvakafanana.
- Special features, likemipendero yakatenderedzwa uye shanduko dzakatsetseka, misa plastiki kuti isabatike nekutsva.
Mafekitori mazhinji anoshuma kuti aya akagadziridzwa screw dhizaini anotungamira kukurumidza kugadzirwa uye mashoma akarambwa zvikamu. Ivo zvakare vanoona yakasimba weld mitsetse uye zvakanyanya kunyange shrinkage, zvinoreva zvirinani zvigadzirwa.
Advanced Temperature uye Pressure Control
Kunyatso kudzora tembiricha uye kudzvanywa kwakakosha pakugadzira emhando yepamusoro zvikamu zvepurasitiki. Iyo PE PP jekiseni rekuumba screw barrel inouya neakakwira masisitimu anotarisisa uye kugadzirisa aya marongero munguva chaiyo. Iyi tekinoroji inochengeta purasitiki yakanyungudutswa patembiricha yakakwana uye kudzvanywa painofamba nemudhiramu.
