I. Ibanga Elijwayelekile Lokulawula Isivinini Solayini
Isivinini somugqa we- Ulayini wokukhiqiza wendwangu we-PTFE osezingeni eliphezulu uvame ukulawulwa ngaphakathi kwebanga elingu-2 kuye ku-15 m/min, ububanzi obujwayelekile bezinzile buba ngu-3 ukuya ku-8 m/min. Izindwangu ezizacile noma eminye imigqa enesivinini esikhulu ingafinyelela ku-10 kuya ku-15 m/min. Uma sithatha njengesibonelo imfuneko ye-sintering engu-1.5 kuya kumaminithi angu-3 kanye nobude be-ovini obusebenzayo obungamamitha angu-20, isivinini somugqa wethiyori singaba cishe ngu-6.7 kuya ku-13.3 m/min. Empeleni, imajini yokuphepha kufanele igcinwe, ngesivinini sangempela esivame ukumiswa ku-60% kuya ku-80% womkhawulo ophezulu, ngaleyo ndlela isebenze ngokujwayelekile kububanzi obungu-4 kuya ku-10 m/min.
II. Izithiyo ezivela ku-Impregnation Penetration and Coating Processes
1. I-Impregnation kanye nesikhathi Sokungena
Njengoba kuphawulwe umkhiqizi wendwangu ye-Jiangsu PTFE enezinga eliphezulu lokushisa: indwangu ye-fiberglass kufanele igcwale ngokugcwele nge-emulsion ye-PTFE futhi ingene ngaphakathi kwezinqwaba zefiber. Uma isivinini somugqa siphezulu kakhulu, ukumiliswa okunganele kwenzeka, okuholela kalula ekulambeni kwe-resin yangaphakathi, imicu eyomile, kanye nezakhiwo zokunamathela nokukhulula ezisengozini. I-emulsion viscosity, ukugxila kokuqinile, kanye nokuminyana kokuluka kwendwangu (izindwangu eziwugqinsi, ama-weave aqinile) konke kunciphisa izinga lokungena, okusho ukuthi izindwangu eziwugqinsi neziminyene kufanele zisetshenziswe ngesivinini esiphansi.
2. Ukuqina Kokumboza kanye Nenombolo Yokudlula Kwesicelo
Indwangu yezinga lokushisa eliphezulu ivamise ukudinga ukucwiliswa okuningi kanye nokudlula kwe-sintering (okungenani amaphasi angu-2 ukuya kwangu-3, ngezinye izikhathi kufika kokungu-6 noma ngaphezulu). Isendlalelo ngasinye sokumboza kufanele sibe mncane ukuze sifinyelele ukunamathela okungenasici. I-pass yokuqala ihloselwe ukumisa ngokugcwele indwangu yesisekelo, ngakho-ke isivinini ngokuvamile sihamba kancane; amaphasi alandelayo anganyuswa ngokusesilinganisweni, kodwa iphasi ngalinye kufanele liqinisekise izinga elanele kanye nokulinganisa okuphelele.
III. Izithibelo Ezisuka Ekomisweni, I-Sintering, kanye Nokusebenza Kwezisetshenziswa
1. Isikhathi sokuhlala sokwelashwa kokushisa kanye nobude behhavini
Indwangu emanzi kufanele yomiswe, i-sintering (ku-380-400°C ukuze ihlanganise izinhlayiya ze-PTFE zibe ifilimu), bese iyapholisa. Isiteji se-sintering ngokuvamile sidinga amashumi amasekhondi ukuya kumaminithi ambalwa. Isivinini somugqa silingana nobude be-ovini obusebenzayo obuhlukaniswe isikhathi esidingekayo sokwelashwa kokushisa. Uma ubude behhavini bulungisiwe, uma ukucwilisa kudinga amaminithi angu-2, isivinini sinqunyelwe cishe ku-5 kuya ku-10 m/min. Ijubane eleqile liholela ekungeneni okungaphelele kwento enamathelayo, ibe mhlophe, ukunganamatheli kahle, kanye nokwakheka kwamaphinifa namabhamuza.
Ukuzungeza komoya oshisayo okusebenzayo kanye nezinga lokushisa lehhavini elifanayo linganciphisa isikhathi sokwelashwa kokushisa, okuvumela isivinini somugqa esisheshayo. Ngokuphambene, ukusatshalaliswa kwezinga lokushisa okungalingani noma ukugeleza komoya okunganele kudinga isivinini esinensayo ukuze kuqinisekiswe ukuhambisana kwengubo yonkana ububanzi bendwangu.
IV. Imikhawulo evela ku-Substrate, Emulsion, kanye Nezimfuneko Zekhwalithi Yokugcina
1. Ukuqina Kwe-substrate, Isisindo, Nobubanzi
Izindwangu ezincanyana kakhulu (isb., 0.08 mm) zingasebenza ngesivinini esingaphezu kuka-10 m/min, kuyilapho izindwangu eziwugqinsi zika-0.3 kuya ku-0.5 mm noma ngaphezulu, kanye nezindwangu eziqinile, eziwugqinsi, zidinga isivinini esincane (2 kuya ku-5 m/min) ngenxa yokudlulisa ukushisa kancane. Izindwangu ezinobubanzi obubanzi zijwayele ukuphambana nokungafani ngesikhathi sokukhulelwa nokomiswa, ngokuvamile okudinga ukuncishiswa kwesivinini ukuze kuqinisekiswe ukufana okuphelele.
Uketshezi olufakwayo olunokuqukethwe okuqinile okuphezulu kanye ne-viscosity ephezulu inamazinga okungena ahamba kancane, adinga isivinini esiphansi somugqa. Izinhlobo namanani ama-ejenti wokumanzisa kanye nokujiya ekubunjweni kuthinta isivinini sokumanzisa kanye namazinga okuphelelwa amanzi emzimbeni, okuthonya ngokuqondile isivinini esiphezulu esivumelekile somugqa.
3. Izidingo Zebanga Lomkhiqizo Wekhwalithi
Kuzinhlelo zokusebenza ezidinga ikhwalithi ephezulu, njengokubhaka ukudla nezindwangu ezisoda nge-elekthronikhi, izimfuneko zokubala izimbobo, ukushelela kwendawo, nokubekezelela ukushuba ziqinile kakhulu. Ezimweni ezinjalo, isivinini kufanele ngokuvamile inikelwe ikhwalithi, ukugcina isivinini somugqa sisezingeni eliphansi ukuze kuqinisekiswe ukunamathela okuminyene, okunganasici.
