Iyini i-PTFE?
I-PTFE evame ukubizwa ngokuthi "inkosi yepulasitiki", iyi-polymer ye-polymer eyenziwe nge-tetrafluoroethylene njenge-monomer.Yatholwa nguDkt. Roy Plunkett ngo-1938. Mhlawumbe usazizwa uxakile ngale nto, kodwa uyalikhumbula ipani elinganamathi esalisebenzisa?I-pan non-stick imbozwe nge-PTFE enamathela ebusweni bepani, ukuze ukudla kunganamatheli phansi epanini, okubonisa ukumelana nokushisa okuphezulu kwe-PTFE nezici zokugcoba eziphezulu.Namuhla, PTFE powder izinto zokusetshenziswa zenziwa imikhiqizo yomumo ehlukahlukene, ezifana PTFE amashubhu, PTFE ifilimu elincanyana, PTFE imigoqo, futhi PTFE amapuleti, okuyinto zonke ezisetshenziswa emikhakheni ehlukene.Okulandelayo, sixoxa ngokusetshenziswa kwamashubhu e-PTFE kumadivayisi ephrinta e-3D.
Ingabe i-PTFE Inobuthi?
Isihloko sokuthi ingabe i-PTFE inobuthi siyimpikiswano futhi i-PTFE empeleni ayinabo ubuthi.
Kodwa lapho i-PFOA (i-Perfluorooctanoic Acid) yengezwe ngaphambilini ezithakweni ze-PTFE, ubuthi bukhishwe lapho busetshenziswa emazingeni okushisa aphezulu.I-PFOA inzima ukucekela phansi imvelo, futhi ingase ingene kubantu nakwezinye izinto eziphilayo ngezinto ezibonakalayo, umoya namanzi, futhi ngokuhamba kwesikhathi kungaholela emazingeni okuzala aphansi nezinye izifo zamasosha omzimba.Kodwa manje i-PFOA ivinjelwe yiziphathimandla ukuthi iyengeze ezithakweni ze-PTFE.Yonke imibiko yethu yokuhlolwa kwezinto ezingavuthiwe iphinda ikhombise ukuthi ayikho ingxenye ye-PFOA.
Kungani amaphrinta e-3D esebenzisa amashubhu e-PTFE?
Ngokuthuthuka okusheshayo kweThe Times, iphrinta ye-3D iwubuchwepheshe bokubumba ngokushesha, okwaziwa nangokuthi ukukhiqiza okungeziwe.Kuyinqubo yokuxhuma noma yokwelapha izinto ezingaphansi kokulawulwa kwekhompyutha ukuze kukhiqizwe izinto ezinezinhlangothi ezintathu, ngokuvamile kusetshenziswa ama-molecule awuketshezi noma izinhlayiya zempushana ukuze zihlangane ndawonye futhi ekugcineni zakhe izinto ungqimba ngongqimba.Njengamanje, ubuchwepheshe bokubumba bokuphrinta be-3D buvame ukufakwa: indlela yokuncibilika yokuncibilika, njengokusetshenziswa kwe-thermoplastic, izinto ezivamile ze-crystal system metal, ijubane layo lokubumba lihamba kancane, futhi ukuncibilika kwezinto ezibonakalayo kungcono;
Nokho, amaphrinta e-3D anefa elingokomlando lekhanda elibuhlungu, kulula ukulixhuma!Nakuba izinga lokuhluleka kwephrinta ye-3D liphansi, uma lenzekile, ngeke lithinte ikhwalithi yokuphrinta kuphela, kodwa futhi lichithe isikhathi nezinto zokunyathelisa, futhi lilimaza ngisho nomshini.Abantu abaningi basola ukuthi ishubhu lomphimbo belishisa kakhulu ngoba lakhiwe ngesithako.Ngenxa yokuthi izinto zebanga lobunjiniyela zidinga izinga lokushisa eliphezulu eliqhubekayo, izidingo zezingxenye ziphezulu kakhulu.Ngakho-ke, iphrinta ye-3D isebenzisa ishubhu ye-PTFE njengeshubhu yokudla.Izinto eziningi zokusetshenziswa zidinga ukuthuthelwa ekhanda lephrinta esimweni sokuncibilika, futhi ishubhu lokuthutha kufanele lihlangabezane nezidingo zesikhala sephrinta, ngakho manje abakhiqizi abaningi bashintshela ku-iron fluorine dragon tube eyakhelwe ngaphakathi, udrako we-iron fluorine nensimbi engagqwali. conductivity ezishisayo iphansi, kunganciphisa ngempumelelo izinga lokushisa emphinjeni, nge iron fluorine dragon tube, ukuxhuma izinga lokuhluleka liyancipha kakhulu.Ngakho lokhu ukukhetha okungcono kakhulu kwamaphrinta we-3D.
Uma usebhizinisini lokuphrinta le-3D, Ungase Uthande
Okulandelayo isingeniso esijwayelekile sezici eziyinhloko zamashubhu e-PTFE:
1. Okunganamatheli: Ayinambithisi, futhi cishe zonke izinto azihlanganisiwe kuyo.
2. Ukumelana nokushisa: i-ferroflurone inokumelana nokushisa okuhle kakhulu.Umsebenzi ojwayelekile ungasetshenziswa ngokuqhubekayo phakathi kuka-240 ℃ no-260 ℃.Isikhathi esifushane ukumelana nezinga lokushisa ukuya ku-300 ℃ nendawo yokuncibilika engu-327 ℃.
3. Ukugcotshwa: I-PTFE ine-coefficient ephansi yokungqubuzana.I-coefficient yokushayisana iyashintsha lapho umthwalo uslayida, kodwa inani liphakathi kuka-0.04 no-0.15 kuphela.
4. Ukumelana nesimo sezulu: akukho ukuguga, nempilo engcono engagugi kupulasitiki.
5. Ayinabuthi: endaweni evamile phakathi kuka-300 ℃, ine-inertia yokuphila futhi ingasetshenziselwa imishini yezokwelapha nokudla.
Ukuthenga ishubhu ye-PTFE efanele akukhona nje kuphela ngokukhetha imininingwane ehlukene yezinhlelo zokusebenza ezahlukene.Okuningi ukukhetha umkhiqizi onokwethenjelwa.I-Besteflon Fluorine plastic Industry Co., Ltd. igxile ekukhiqizeni amapayipi namashubhu ekhwalithi ephezulu we-PTFE iminyaka engu-15.Uma kukhona imibuzo nezidingo, sicela ukhululeke ukuxhumana nathi ukuze uthole izeluleko ezengeziwe zochwepheshe.
