I. Izidingo Eziyisisekelo Zezinga Lokupholisa
Dlula ngokushesha endaweni ezwela icrystallization Indawo encibilikayo ye-PTFE ingu-327°C, futhi izinga lokushisa elijwayelekile le-sintering lisukela ku-380°C ukuya ku-400°C. Ngesikhathi sokunciphisa izinga lokushisa, imfuneko eyinhloko ukuwela ngokushesha indawo yokushisa engaba ngu-310 ~ 315 ° C lapho izinga lokucwebezela likhuphuka kakhulu.
Izindlela zokusebenza ezinconyiwe Ngokushesha ngemva kokuphuma esithandweni somlilo, sebenzisa ukupholisa komoya ngempoqo, ukupholisa umoya ocindezelwe, noma sebenzisa amarola okupholisa / amasistimu okupholisa amanzi ukuze wehlise ngokushesha izinga lokushisa lendwangu libe ngaphansi kuka-250°C.
Izinkomba zereferensi yesilinganiso sokupholisa Kuncike ebugqileni bomkhiqizo, izinga lokupholisa elijwayelekile akumele libe ngaphansi kuka-30~50°C/min. Ngendwangu yegeji encane yezinga lokushisa eliphezulu (0.08mm~0.25mm), ukupholisa komoya kungafinyelela izinga lokupholisa elingaphezu kuka-100~200°C/min, okuvumela ukudlula ngokushesha endaweni ebucayi yekristalu.
I-Crystallinity inquma izici zomkhiqizo oyinhloko Izindlela zokupholisa zilawula ngokuqondile ubucwebe be-PTFE, obuqhubeka nokusho izici ezibalulekile zokuhlanganisa ezihlanganisa ukuguquguquka, ukunamathela kanye nokusebenza okungeyona induku.
Ukuqhathaniswa Kokusebenza Phakathi Kokupholisa Okusheshayo Nokunensa
Imodi Yokupholisa |
I-Crystallinity |
I-Coating Performance Behaviour |
Ukupholisa Ngokushesha (Ukucisha) |
Phansi (cishe. 45~50%) |
Ithambile, ukuqina okuhle kakhulu, indawo ebushelelezi, ukunamathela okuqinile, indawo ephakeme engagxili, imelana nokuqhekeka nokuqhekeka. |
Ukupholisa Kancane (Ukupholisa kwesithando) |
Phezulu (ngaphezu kuka-60~70%) |
Iqinile ngokuqhathaniswa, i-brittleness ephezulu, ijwayele ukushwabana futhi ixebuke, ukukhiqizwa kwe-microcrack, impilo yesevisi efinyeziwe yomphumela wokungakhuni |
Incazelo ye-Microstructural Ukupholisa okusheshayo kuvimbela ukukhula kwama-spherulite osayizi omkhulu futhi kwakha isakhiwo esihle se-microcrystalline. Lokhu kunikeza ifilimu ye-PTFE iminyene kanye ne-ductile eyengeziwe, kuyilapho kunciphisa ingcindezi eyinsalela phakathi kwe-coating ne-fiberglass substrate.
III. Amaphuzu Abalulekile Okulawula Ekukhiqizeni Okuningi
Isiqinisekiso sokupholisa okufanayo Ukupholisa ukugeleza komoya okupholisa noma amarola okupholisa kufanele kugcine izinga lokushisa elingashintshi phakathi nobubanzi bendwangu. Ubucwebe bendawo obungalingani buzoholela endaweni enamabala noma imibimbi.
Gwema ukushaqeka okushisayo okwedlulele Ngendwangu ewugqinsi eshisa kakhulu (u-0.5mm nangaphezulu), isifutho samanzi esiqondile noma ukuthintana ngokushesha namarola abandayo kakhulu kungase kubangele ukonakala okukhulu okubangelwa ukushwabana okushisayo okungafani phakathi kwe-substrate nokumbozwa. Ukugeleza komsebenzi okuncomekayo kuwumoya onamandla opholisa phansi uze ube ngaphansi kuka-250°C ngaphambi kokupholisa okwengeziwe.
Ukuphathwa kokupholisa kwe-multi-pass sintering Ezinqubweni zokufakela izinto eziningi kanye ne-multi-sintering, ukupholisa okusheshayo okumaphakathi kuyamukeleka emijikelezweni ephakathi ye-sintering. Kodwa-ke, isinyathelo sokugcina se-surface sintering kumele sisebenzise ukupholisa okusheshayo ukuze kuvikeleke ukusebenza kahle kwendawo yokusebenza.
IV. Isifinyezo esiyinhloko
1. Ukupholisa okusheshayo kuyisibopho sokuthungathwa kwendwangu ye-PTFE ukuze unike amandla i-PTFE encibilikisiwe ukuthi yeqe indawo yecrystallization yezinga eliphezulu lokushisa ngokushesha.
2. Ukupholisa okusheshayo kukhiqiza ukwakheka kwe-microcrystalline e-crystallinity ephansi, okuyisihluthulelo sokuguquguquka okuvelele, ukumelana nokugoqa kanye nokusebenza okungapheli okungapheli.
3. Lawula ngokuqinile ukufana kokupholisa, uvimbele ukushaqeka okushisayo, futhi ulinganise amashejuli okupholisa e-multi-stage sintering ukuze uzinzise ikhwalithi yomkhiqizo engaguquki.
