Yini EyenzaAmabhande Okuhambisa I-KevlarIngabe Umelana Nokushisa Okuphezulu?

Inzuzo yeKevlar

I-Kevlar iyi-fiber ye-aramid enamandla aphezulu, elula eyakhiwe yiDuPont, enikeza:

• Ukumelana nokushisa okumangalisayo: Ukusebenza okuqhubekayo kuze kufike ku-260°C; ukuphakama okusheshayo kufinyelela ku-550°C
• Amandla aphezulu okubamba: Iphatha imithwalo esindayo ngaphandle kokunwebeka noma ukuphuka
• Ukunwebeka okuphansi: Ngokuvamile kungaphansi kuka-0.5%, okuqinisekisa ukuzinza kobukhulu ngaphansi komthwalo
• Ilula: Kufika ku-30% ilula kunezintambo zensimbi ezinamandla alinganayo, okunciphisa ukusetshenziswa kwamandla
• Ukumelana namakhemikhali nokugqwala: Akuthinteki umhwamuko wamanzi, amaminerali agqwalisayo, kanye namakhemikhali amaningi

Izingxube Ezihlanganisiwe Zokusebenza Okuthuthukisiwe

Amabhande amaningi okuhambisa e-Kevlar ashisa kakhulu afaka izinto ezengeziwe ukuze kuthuthukiswe izakhiwo ezithile:

Izinhlobo Zamabhande Okudlulisa I-Kevlar Okushisa Okuphezulu

1. Amabhande e-Kevlar alukiwe ngendlela eyisicaba

Kwenziwe kusetshenziswa amasu okuluka aqinile, anezingqimba eziningi. Ubukhulu obujwayelekile busukela ku-0.7mm kuya ku-6mm, ububanzi bufika ku-500mm noma ngaphezulu. Lawa mabhande aqinile, aqinile, futhi avimbela ukumaka noma ukushaqeka kokushisa ezintweni ezihanjiswayo.

2. Amabhande e-Kevlar Mesh ambozwe yi-PTFE

I-substrate ye-Kevlar embozwe nge-PTFE (Teflon) inikeza indawo enganamatheli, engamelani namakhemikhali. Lawa mabhande ane-mesh evulekile alungele ukomisa ama-oven, ukwelapha i-PCB, kanye nemigqa yokomisa yendwangu. Amandla okunamathela angafinyelela ku-3,500/3,300 N/5cm.

3. Amabhande e-Kevlar Felt

Ukwakhiwa kwefelthi ye-Kevlar enezingqimba eziningi enezingqimba zokuqinisa ezi-5 noma ngaphezulu. Ukumelana nokushisa kufika ku-510°C, ubukhulu busukela ku-5mm kuya ku-14mm. Itholakala ngokulukwa okungapheli noma ngezinamathiselo zemishini.

4. Amabhande Endwangu KaKevlar Ambozwe Nge-PTFE

Indwangu eyisisekelo ye-Kevlar embozwe nge-resin ye-PTFE ukuze isetshenziswe edinga izindawo ezinganamatheli kanye nokumelana namakhemikhali. Izinga lokushisa: -140°C kuya ku-360°C. Amandla okunamathela afinyelela ku-1,500/1,250 N/cm.

Izicelo Eziyinhloko Zemboni

Ukukhiqiza Ingilazi

Isicelo esinzima kakhulu samabhande okuhambisa e-Kevlar ashisa kakhulu. Amabhande athutha izinto zengilazi eshisayo—i-stemware, amafasitela omshini wokuwasha, izinto zokudlala—kusukela ekwakheni imishini yokucindezela kuya kuma-lehrs anamathelayo, lapho amazinga okushisa ephakeme khona futhi ukushaqeka kokushisa kuyingozi eqhubekayo. Ukumelana nokushisa kwebhande kuvimbela ukumaka, ukucwebezela, noma ukuguquka kwezindawo zengilazi.

Ukucubungula Ngensimbi Nokusetshenzwa Kwensimbi

Ukudlulisa amashidi ensimbi ashisayo, ama-castings ahlanganisiwe, i-ore e-sintered, kanye ne-clinker. Ezitshalweni zensimbi, amabhande e-Kevlar aphatha izinto ezishisayo ezivela ezinqubweni zokuphotha eziqhubekayo noma ze-galvanizing, agcina ubuqotho lapho amabhande enjoloba ajwayelekile angaqina futhi aqhekeke khona. Amabhande e-Super-K® asekelwe ku-EPDM angenye indlela yokumelana nokushisa, kodwa i-Kevlar inikeza amandla aphakeme okubamba kanye nokwakhiwa okulula.

Izimayini kanye Nezimboni Ezinzima

Amabhande okuhambisa impahla anezidumbu ze-Kevlar® athatha indawo yamabhande e-polyester/nylon kanye nezintambo zensimbi ezivamile. Izinzuzo zifaka phakathi isikhathi sokuphila esengeziwe, ukumelana okuncishisiwe kokugoqa, ukusetshenziswa kwamandla okuphansi, kanye nama-slices ambalwa. Umklamo olula unciphisa izidingo zesakhiwo semishini kanye nezindleko zokusebenza.

Imisebenzi Yokomisa Nokuphola

Amabhande e-Kevlar ane-PTFE asetshenziswa ku:

• Imishini yokomisa izindwangu eyisicaba kanye nemigqa yokuthungela
• Imigudu yokwelapha ene-infrared ekude
• Ama-oven okomisa e-PCB
• Imigqa yokuphelelwa amanzi emzimbeni yezimboni
• Ukufakwa kwe-lamination kanye nokuhlelwa kokuncipha kwezingubo

Idizayini ye-mesh evulekile ivumela ukuhamba komoya kuyilapho ubuso be-PTFE obunganamatheli buqinisekisa ukukhishwa kwezinto kalula.
