I-Polyurethane Vibrating Screen: Ukuthintela ukugaywa kwezinto ngokuhlukaniswa kwezinto ezinzima

Ukuthi I-Polyurethane Vibrating Screens Isaphazamisa Kanjani Ukuhlatshwa Ngokusebenzisa Ukupheliswa Kwegcinezelo

Umkhondo: Ukuxhumana Okunciphakelela Kwezinye Nokuthatha Igciniko Ngaphandle Kokuqhakamshelwa Kwemitholampilo Engcono

Amasikrini athintana atholakala kwi-polyurethane ayasiza ekuvikeleni izici zezinto ngoba zinezinhloso eziphazanyayo. Le ndawo yenyani isebenza ngokuthatha ikinetic energy lapho izinto ezincane zizama kuzo. Amasikrini amanzi ahlotshwayo asodwa ngokugcwele. Avela kuwo imithombo engcono eyayika izinto eziphephile. Uma i-polyurethane isebenzisana nethu, iqhubeka ithinta kancane, okusho ukuthi le sifanekiso siyasebenza kude—kungekungama 30 kuze kube 50 phambi kolwandle olunye. Lokhu kuyahlola konke okufana nezindlela ze-pharmaceutical noma ama-ceramic powders afuduka ngokushesha uma kuthathwa ingcinaba. Okutheni kutheni ke kukhona ukuthi imodi ivikeleka ngexesha angaphandle kokwenza izinkinga ezimangalisayo. Angaphandle kokufupha, le zinto ezincane zihamba ngokulula. Kukhona amacebiso ethu abeke ukuthi i-polyurethanes efanisiwe ngempumelelo ingavikela ukuthintana ngama-2/3 kunazo amasikrini akrusi. Le nzuzo ibaluleke kakhulu xa kusekelwa kumgogogo wamakhristalu ngexesha lenqaku esondeni kumendini yemfundo.

Umbono: Ukuphephelwa kwe-62% kwesithasisiwa kwe-granule ku-FDA ku-Dhulomane Lwesicelo Esilungileyo

Abayenzelwa izicelo zesiphetho bavumela ukuthuthuka okukhulu ekusebenziseni amascreen ase-polyurethane:

• kuphephelwe kwe-62% esithasisini kwe-granule kumakhasi atholakala kwaspirini (imbono yedatha ye-FDA engu-2023)
• ukuphephelwa kwe-40% kuhlukaniswa kwemipowudhi yesicelo sezibalo esivimbela umoya (APIs)
• Ukunqamuzeka kabusha kwezinkinga zokufaka kwezintshukumo ngaphandle kwegesi lemesh le-stainless

Ukuthola kwi-vitamin C granules kwakubonisa okuthile okuthakathaka ngamathetho ekusikoleni. Xa usebenzisa izikrini ze-polyurethane endala, zazimemba nge-98.2% yokuphila kwezinto ezincane kunalo 78.5%. Lokhu kwenza uhlelo oluhle kakhulu kokuthi izitabhele ziyaqeda kanjani kamva. Yini engcwele? Lezi zikrini ziyahlukanisa ukugcinwa ngokulinganayo phakathi kwezinye, ngakho akukho ziphuzu ezithintekayo eziphazanyiswa izinto ezinzima ngduring processing. Uma ubuka okutholile abaviki base polymer kamanje, le ndawo eyisiseko ye-dynamic imine kuleli gama libe libe lishuntyisela amandla ngendlela ethembekile phakathi kwezinkinga ezahlukeneyo. Futhi lokhu kukhona kuyaphilisa kakhulu ukuze kufihlelwe i-Good Manufacturing Practice standards abadinga abasebenzisa izinkampani zezempilo.

Ukukhetha i-Polyurethane Vibrating Screen Ehlukileyo Izinto Ezinzima

Ukuvikela izinto ezinzima njenge-granules zezempilo noma i-flakes zabudla kudinga ukumiswa okuphathelene kwe-screen. Isikrini esihlelwe ngokuphelele se-polyurethane sikhuphula ukuchithwa ngokulungiselela amapharamitha amathathu ekusobala nezimo zezinto.

Ukufaka kuye i-Mesh Profile, i-Open Area, kanye ne-Shore Hardness kwi-Sensitivity Yezinto (isb. I-Granules Ezinchithekileyo, I-Flakes, noma I-Powders Ezinamandla Ekunquma)

Ukuzivikela kokuqhakazeka, uzilungelele lezi zinkinga eziphakanyisayo:

• I-Mesh Profile : Izindawo ezingenanto zikhubaza ukuthinta kwesibhedlela kuma-granules angachithi, ngelixa izinhlelo ezingenanto zakhupha isimo sokuchithwa kuma-flakes
• I-Open Area : Amaperesenti athile (30–40%) avikela ukunquma okuvuthiwe ngu-capillary kuma-powders angahambeki ngaphandle kokudinga ukuthintana okuningi kakhulu
• I-Shore Hardness : Izisikrini ezizizayo (70–80 Shore A) zivikela ukuthintana kuma-crystals angachithi; izigaba ezikhulu (90+ Shore A) zifanele kakhulu kuma-blends angamandla angaphansi

Ukumiswa okufaneleyo kususa ukugaywa ngaphansi kuka-60% kunazo ezizenzakalelayo emathubini (I-Journal ye-Technology ye-Powder 2023). Sicela uvikele izilungiselelo ngokusebenzisa izimboni zomthelela ngaphambi kokusebenzisa ngokuphelele.

I-Polyurethane vs. I-Stainless Steel Vibrating Screens: Ukulungiselela Okuphathelene Nezidingo, Ukuhlasekelwa, Nokuphepha Kwesilawuli

Ukuchazwa Kwezinkinga Ezihlukene: Ukuhlongozeka Kwezidingo Nokunciphisa Isimahala Sokulungiswa Ngaphandle Kokuqinisekisa Ukuphepha Kwemithombo

Amathuba okungcola kwezigaba ze-polyurethane esinake kusilawuli ngaphezu kwebingelela njengoba ingena imodi ngenhla yokuthunyelwa kwayo. Izivivinyo zibonisa ukuthi lezi zigaba zizicindeze izinto ezihluphekile ngo-60 futhi kangakanani izikhathi, lokhu kwenza umehluko mkhulu xa kusekelwa izinto ezihlanjuluhlangu. Umsebenzi wokumelana ungakhiqiza amakhristali eziphileneyo njengezemidaza nemaqhasheli ehlayekayo kumoya, lokhu kubangelwa ngendlela ethile efana naleyo izinto zifungashintsha khona. Ngokuphambene, izigaba ze-stainless steel zihandlenza kabanzi ama-30 kuze kube ngu-50 ngaphezulu yomthelelo wamathambo ngoba kunezikhala eziningi phakathi kwamabara futhi azange aphinde aphinde ngazo izivivinyo ezinezimo engcono ngaphandle kokuthinta.

Izinkinga eziphambene kuzo zilandelayo:

• Izinzuzo Ze-polyurethane :
  • izidingo ezingaphezu kuka-3–5×, ekunciphisa isilinganiso sokufakwa kwakhona
  • izindleko zokuhlenga ngonyaka zingaphansi kuka-40%
• Amaphakade we-stainless steel :
  • Ukuphumelela okuphakade kumaterial engcono, engaluthinteki
  • Ukukhathazeka okuhle kumasebe apholile kakhulu

Xa kusekelwa kumaterial engaluthinteki njengamagranules noma amaphakathi, abazalisi abaningi bathola ukuthi okuthintwayo ngu-polyurethane kuthembekile ngoba kungahleli kakhulu ngaphandle kokuthinta izikhathi eziningi zokulunga. Le yindlela ikhona kahle ngokwesikhathi ngaphandle kokuthinta izikhathi eziningi zokulungiswa. I-stainless steel ingathinta izinto ngokushesha kodwa inezindleko - ihlanganisa izinto ezithintekileyo ngokwezimali futhi kudinga ukulunga okujwayelekile. Ngakho-ke xa ukhetha phakathi kwezinketho ezi, cabanga ngendlela yokusebenzisa umaterial. Izinto ezihluphekile zihlala zisebenza kahle kunesilingi yesi-polyurethane ngelixa izinto ezintotshayo ezidinga izilingo ezinkulu zihlala zisebenza kahle kwi-stainless steel.

Imibuzo Evame Ukubuzwa

Kungani kakhwe ukukhetha izihluku ze-vibrating zesi-polyurethane ngaphezu kwe-stainless steel kumaterial ehlinzekile?

Amashini ase-polyurethane anezivikelwayo eziphambene ngezici zazo ezithandekayo, ezingavimba kakhulu amaphakathi, okwaneleke kakhulu kumalayizi ethintela njengegranules yezempilo nezinhlamvu ezinhle.

Kutheni ukunika kwezishini ze-polyurethane ekuskeni izimpilo?

Kubonakale ukuthi ukusebenzisa amashini ase-polyurethane ekuskeni izimpilo akunciphisa ukugayazeka kwemiphefumulo ngama-62% futhi akuphazanyise kabangani imida yesimo sangaphandle kwegesi lika-stainless steel.

Ukufaka kanjani ishini esine-vibrating se-polyurethane ukuze uthole iziphumo ezilungile kangaka?

Landelana iphrofayili ye-mesh, indawo evulekile, nokushesha kuka-Shore nomlando wokuthanda ukuze unciphise konke ukulahlekwa nokugayazeka.
