Isingeniso SePlastiki Extrusion
I-Plastic extrusion ingenye yezinqubo zokukhiqiza ezisetshenziswa kakhulu embonini yepulasitiki, ikakhulukazi kuma-thermoplastics. Ngokufana nokubumba umjovo, i-extrusion isetshenziswa ukudala izinto ezinamaphrofayili aqhubekayo, njengamapayipi, amashubhu, namaphrofayili eminyango. I-extrusion yesimanje ye-thermoplastic ibe yithuluzi eliqinile cishe ikhulunyaka, elivumela ukukhiqizwa kwevolumu ephezulu yezingxenye zephrofayela eziqhubekayo. Amakhasimende asebenzisana nezinkampani ze-plastic extrusion ukuthuthukisa ama-extrusions epulasitiki angokwezifiso ngezidingo zawo ezithile.
Le ndatshana icubungula izinto eziyisisekelo ze-plastic extrusion, ichaza ukuthi inqubo isebenza kanjani, yiziphi izinto ze-thermoplastic ezingakhishwa, yimiphi imikhiqizo evame ukukhiqizwa nge-plastic extrusion, nokuthi i-plastic extrusion iqhathaniswa kanjani ne-aluminium extrusion.
I-Plastiki Extrusion Process
Ukuze uqonde inqubo ye-plastic extrusion, kubalulekile ukwazi ukuthi iyini i-extruder nokuthi isebenza kanjani. Ngokuvamile, i-extruder iqukethe izingxenye ezilandelayo:
I-Hopper: Igcina izinto zepulasitiki ezingavuthiwe.
Okuphakelayo Umphimbo: Iphakela ipulasitiki kusuka ku-hopper kuya emgqonyeni.
Umphongolo Oshisayo: Uqukethe isikulufu esishayelwa injini, esiphusha okokusebenza kuye endaweni yokufa.
I-Breaker Plate: Ifakwe isikrini sokuhlunga izinto kanye nokugcina ingcindezi.
Iphayiphi lokuphakelayo: Idlulisa into encibilikisiwe isuka emgqonyeni iye edayilini.
I-Die: Ilolonga okuqukethwe kuphrofayili oyifunayo.
Isistimu Yokupholisa: Iqinisekisa ukuqina okufanayo kwengxenye ekhishwe.
Inqubo ye-plastic extrusion iqala ngokugcwalisa i-hopper ngezinto ezingavuthiwe eziqinile, njengama-pellets noma ama-flakes. Okubalulekile kufakwa amandla adonsela phansi ngomphimbo wokuphakelayo emgqonyeni we-extruder. Njengoba impahla ingena emgqonyeni, iyashiswa ngokusebenzisa izindawo zokushisa eziningana. Ngesikhathi esifanayo, okokusebenza kuphushwa ngasekugcineni komgqomo ngesikulufu esiphindaphindayo, esishayelwa injini. Isikulufu nokucindezela kukhiqiza ukushisa okwengeziwe, ngakho-ke izindawo zokushisisa akufanele zishise njengezinga lokushisa lokugcina lokukhipha.
Ipulasitiki encibilikisiwe iphuma emgqonyeni ngesikrini esiqiniswe ipuleti le-breaker, elisusa ukungcola futhi ligcine ingcindezi efanayo ngaphakathi kombhobho. Izinto ezisetshenziswayo zibe sezidlula epayipini lokuphakelayo liye endaweni yangokwezifiso, enembobo emise okufana nephrofayili efiswayo ekhishwe, ekhiqiza i-extrusion yepulasitiki yangokwezifiso.
Njengoba impahla iphoqelelwa nge-die, ithatha isimo sokuvuleka kwefa, iqedela inqubo ye-extrusion. Iphrofayili ekhishiwe bese ipholiswa endaweni yokugezela yamanzi noma ngochungechunge lwamaroli okupholisa ukuze iqine.
I-Extrusion Plastics
I-extrusion ye-Plastiki ifaneleka ezintweni ezihlukahlukene ze-thermoplastic, ezishiselwa ezindaweni zazo zokuncibilika ngaphandle kokubangela ukuwohloka kokushisa. Izinga lokushisa le-extrusion liyahlukahluka kuye ngokuthi ipulasitiki ethile. Amaplastiki e-extrusion ajwayelekile afaka:
I-polyethylene (PE): Iphuma phakathi kuka-400°C (ubukhulu obuphansi) no-600°C (ukuminyana okuphezulu).
I-Polystyrene (PS): ~450°C
Inayiloni: 450°C kuya ku-520°C
I-Polypropylene (PP): ~450°C
I-PVC: Phakathi kuka-350°C no-380°C
Kwezinye izimo, ama-elastomers noma amapulasitiki e-thermosetting angakhishwa esikhundleni se-thermoplastics.
Izicelo zePlastiki Extrusion
Izinkampani ze-extrusion zepulasitiki zingakha izingxenye eziningi ezinamaphrofayili angaguquki. Amaphrofayili e-Plastic extrusion alungele amapayipi, amaphrofayili eminyango, izingxenye zezimoto, nokuningi.
1. Amapayipi namashubhu
Amapayipi epulasitiki namashubhu, ngokuvamile enziwe nge-PVC noma amanye ama-thermoplastics, yizinto ezivamile ze-plastic extrusion application ngenxa yamaphrofayili azo alula angama-cylindrical. Isibonelo amapayipi amanzi akhishiwe.
2. I-Wire Insulation
Ama-thermoplastics amaningi anikezela ngokufakwa kahle kukagesi kanye nokuzinza kokushisa, okuwenza afanelekele ukufakwa kwe-extruding kanye nokushelela izintambo nezintambo. Ama-fluoropolymers nawo asetshenziselwa le njongo.
3. Amaphrofayili eminyango nefasitela
Amafreyimu eminyango yepulasitiki namafasitela, abonakala ngamaphrofayili awo aqhubekayo nobude, alungele ukukhishwa. I-PVC iyinto ethandwayo yalolu hlelo lokusebenza nezinye izesekeli zasendlini ezihlobene namaphrofayili e-plastic extrusion.
4. Izimpumputhe
Izimpumputhe, ezihlanganisa ama-slats amaningi afanayo, zingakhishwa ku-thermoplastics. Amaphrofayili avamise ukuba mafishane, kwesinye isikhathi abe nohlangothi olulodwa oluyindilinga. I-Polystyrene ivame ukusetshenziselwa izimpumputhe zezinkuni ze-faux.
5. Weather Stripping
Izinkampani zepulasitiki ze-extrusion zivame ukukhiqiza imikhiqizo yokukhumula isimo sezulu, edizayinelwe ukuthi ilingane kahle eduze kozimele beminyango namafasitela. Irabha iyinto evamile yokuhlubula isimo sezulu.
6. Windshield Wiper kanye Squeegees
Ama-windshield wiper ezimoto ngokuvamile ayakhishwa. Ipulasitiki ekhishiwe ingaba izinto zerabha zokwenziwa ezifana ne-EPDM, noma inhlanganisela yerabha yokwenziwa neyemvelo. Ama-squeegee blades asebenza ngokufana namawipha omoya.
I-Plastic Extrusion vs. I-Aluminium Extrusion
Ngaphandle kwe-thermoplastics, i-aluminium ingaphinde ikhishwe ukuze yakhe izingxenye zephrofayela eziqhubekayo. Izinzuzo ze-aluminium extrusion zifaka phakathi ukulula, ukuqhuba, kanye nokusetshenziswa kabusha. Izicelo ezijwayelekile ze-aluminium extrusion zifaka imigoqo, amashubhu, izintambo, amapayipi, uthango, ojantshi, amafreyimu, namasinki okushisa.
Ngokungafani ne-plastic extrusion, i-aluminium extrusion ingaba ishise noma ibanda: i-extrusion eshisayo yenziwa phakathi kuka-350 ° C no-500 ° C, kuyilapho i-extrusion ebandayo yenziwa ekamelweni lokushisa.
Isiphetho
I-extrusion yepulasitiki, ikakhulukazi kumongo we-China Plastic Pipe Extrusion Line, iyindlela eguquguqukayo nephumelelayo yokukhiqiza izingxenye zephrofayela eziqhubekayo. Amandla ayo okuphatha izinhlobonhlobo ze-thermoplastics kanye nobubanzi bayo bezinhlelo zokusebenza kuyenza ibaluleke kakhulu embonini yokukhiqiza amapulasitiki.
