Chowumitsira pulasitiki, chomwe chimadziwikanso kuti pulasitiki dehumidifier, ndichofunikira pamachitidwe omwe makampani omwe amasintha mapulasitiki.
Awa ndi makina enieni opangidwa kuti athetse chinyezi chomwe chili mu ma granules apulasitiki pakukonza kwawo.
Nazi zifukwa zazikulu zomwe zimakhudza kuyanika ndi mitundu yosiyanasiyana ya dehumidifiers yomwe ilipo.
Pulasitiki dehumidification: mfundo zofunika
Kuyanika ma granules apulasitiki ndikofunikira kuti musunge zinthu zakuthupi, kukulitsa kukongola kwa chinthu chomaliza, kuchepetsa nthawi yokonza, ndikuchepetsa chiwopsezo cha zolakwika zopanga.
Chifukwa chake, zotsatira za kuchotsa chinyezi zimadalira zinthu zosiyanasiyana zokhudzana ndi mawonekedwe a pulasitiki, momwe zinthu zilili kunja, ndi njira zowumitsira.
Zikayikidwa pa kutentha, zinthu zopangidwa ndi thermoplastic, kuphatikizapo tinthu ta pulasitiki, zimakhala zosavuta kufewa. Zinthu zimenezi zimagawidwa m'magulu awiri: hygroscopic thermoplastics , zomwe zimayamwa chinyezi mkati ndi kunja, ndi non-hygroscopic thermoplastics , zomwe zimasunga chinyezi pamwamba pokha.
Kusiyanitsa kumeneku ndikofunikira pakusankha chowumitsira choyenera kwambiri pakampani yopanga mapulasitiki.
Zinthu zina zomwe zimathandizira kuyanika bwino ndi izi:
- Mame.
Kutentha komwe mpweya umakhala wodzaza ndi chinyezi. Kuwongolera bwino kwa mame kumalepheretsa kuyanika panthawi yowumitsa.
- Mtundu ndi mawonekedwe azinthu.
Izi zimakhudza njira zoyanika zomwe zimagwiritsidwa ntchito.
- Mtengo wa Airflow.
Zikasinthidwa malinga ndi zofunikira zakuthupi, zimalola kuyanika kolondola komanso kothandiza.
- Ikani kutentha.
Izi zimakhudza magwiridwe antchito a dehumidifier ndipo zimatha kusintha zinthu, makamaka pazinthu zapamwamba monga bioplastics.
- Kuyanika nthawi.
Ngati zitatenga nthawi yayitali, zimatha kuyambitsa kutentha, thupi, kapena kuwonongeka kwazinthu zakuthupi ndikusokoneza dongosolo la kupanga.
- Chinyezi choyambirira komanso chomaliza.
Kuyeza chinyezi kumayambiriro kwa ndondomekoyi ndi kukhazikitsa chinyezi chomaliza chomwe mukufuna ndikofunikira kuti mukhazikitse zowumitsa bwino.
Kusankha chowumitsira choyenera kuyenera kulinganiza zinthu zonsezi.
Mitundu ya zowuma pulasitiki
Popeza pali zinthu zambiri zomwe muyenera kuziganizira posankha chowumitsira pulojekiti yanu, pali njira zambiri zosinthira makina.
Nawa machitidwe ena:
- Mavuvuni otentha otentha.
Dongosolo lamanja lokwera mtengo ndiloyenera pazinthu zazing'ono. Zimapereka mphamvu zochepa pa ndondomekoyi ndipo sizikutsimikizira zotsatira zabwino.
- Zowumitsira mpweya otentha.
Lolani kuyanika kosalekeza ndipo mutha kuyika pamakina kapena pambali. Komabe, ali ndi ndalama zambiri zamagetsi, amakhudzidwa ndi chilengedwe, ndipo ali oyenera pazinthu zopanda hygroscopic.
- Zowumitsa zowumitsa.
Perekani njira yowumitsa mosalekeza, kuchepetsa nthawi yokonza, ndipo musalole kuti zinthuzo zikhale zovuta. Komabe, iwo ndi oyenera kokha pakupanga ang'onoang'ono amayendetsa ndipo ali ndi mtengo wogula wokwera.
- Ma dehumidifiers oponderezedwa.
Lolani kuyanika kosalekeza, kumafuna malo ochepa, ndipo ikhoza kuikidwa pambali pa makina. Zimagwira ntchito pongopanga zing'onozing'ono, zimapanga ndalama zambiri zosalunjika, komanso zimapereka njira zochepa zowongolera.
- Zowumitsira ma microwave.
Onetsani pulasitiki pachiwopsezo cha kuwonongeka kwa zinthu, kuwapangitsa kukhala osayenera kugwiritsidwa ntchito m'mafakitale.
- Ma infrared dehumidifiers.
Lolani kuyanika kosalekeza ndikufulumizitsa ndondomekoyi. Zoyenera kupanga zozungulira zazikulu zokha, zimakhala ndi ndalama zambiri komanso kugwiritsa ntchito mphamvu, ndipo kuwongolera kumakhala kovutirapo ndi chiwopsezo cha kuipitsidwa kwazinthu.
- Zowumitsira ma molekyulu a sieve.
Lolani njira yowumitsa mosalekeza, ikhoza kukhazikitsidwa pamakina kapena pambali, ndipo mulibe malire pa kuchuluka kwa kupanga. Komabe, mame awo amakhala osagwirizana, ndipo masefa a molekyulu amawonongeka msanga, zomwe zimafunikira kusinthidwa pafupipafupi.
- Zowumitsa rotor.
Perekani zinthu zatsopano poyerekeza ndi zothetsera zakale. Gudumu, chinthu chapakati pa dongosololi, chimazungulira chifukwa cha stepper motor, ndipo mpweya umadutsamo m'magawo atatu: kupyolera mu dehumidification, mpweya umauma, kutentha kutentha komwe kumafunidwa, ndikugwiritsidwa ntchito kuumitsa ma granules apulasitiki. Kenaka, kubwezeretsedwa kwa mpweya wotentha kumapangidwa ndi chipinda ndi fani yodzipereka. Pomaliza, kuziziritsa kwa mawonekedwe kumachitika, komwe kumakhazikika ndikubwerera ku gawo loyamba lowumitsa.
Chowumitsira chozungulira chimaonedwa kuti ndi chida chapamwamba kwambiri. Mwachitsanzo, chomwe kampani ya VISMEC inapereka ndi makina ang'onoang'ono omwe safuna kukonzedwa bwino ndipo ali ndi gudumu lokhala ndi chisa cha uchi lomwe limalowa m'malo mwa ma sefa achikhalidwe.
Kuphatikiza apo, makina owumitsira awa amapereka: kutentha kouma mpaka 180°C popanda kugwiritsa ntchito madzi ozizira, dothi lokhazikika komanso losinthika limatsika kufika -50°C , zomwe zimathandiza kuchepetsa mphamvu zomwe zimagwiritsidwa ntchito ndi 40% .
Choumitsira chozungulira chilinso ndi MPM (Material Protection Management), dongosolo lopangidwa kuti liteteze zinthuzo kuti zisanyowe kwambiri komanso kuwonongeka, ndi SLS (Safety Loading System), dongosolo loteteza lomwe limaletsa zinthu zosanyowa kuti zisafike pamakina opangira.
