Ifilimu yombala ye-PTFE iwuhlobo olusha lwe-c-grade insulation material esebenza kahle kakhulu, efanele izidingo ezikhethekile, njengezinsimbi zikagesi ezimakwe ngombala noma ngocingo, njll. Kuyinto ebaluleke kakhulu futhi ebalulekile embonini yomsakazo, ezondiza. imboni kanye nesayensi ye-elekthronikhi nobuchwepheshe obusezingeni eliphezulu.
Ifilimu yombala we-PTFEwuhlobo olusha lwe-c-grade insulation material olusebenza kahle kakhulu, olufanelekela izidingo ezikhethekile, njengamathuluzi kagesi amakwe ngombala noma ngocingo, njll. Kuyinto ebaluleke kakhulu futhi ebalulekile embonini yomsakazo, embonini yezokundiza nokusika. -isayensi ye-elekthronikhi nobuchwepheshe.Ekusetshenzisweni kokuqala kwe-PTFE plastic insulated wire kanye nekhebula, yayilinganiselwe kuphela izintambo zangaphakathi kanye nezintambo eziholayo zemishini kagesi neye-elekthronikhi endaweni enezinga eliphezulu lokushisa kwezindiza, imikhumbi namanye amagumbi enjini emkhakheni wezempi.Ngokukhuthazwa kobuchwepheshe bokulungiselela, i-PTFE iye yanwetshwa kancane kancane emigqeni yokufaka imishini kagesi neye-elekthronikhi endaweni yokushisa ephezulu.Esikhathini esedlule, amafilimu e-PTFE afuywayo ayenemibala yemvelo yezinto zokwakha (ngoba amafilimu e-PTFE akulula ukuthi abe nemibala).Ukuze kuhlukanise imigqa engenayo nephumayo yamasignali ahlukene okudlulisela futhi kuwenze kube lula ukuhlukaniswa, indlela yokumboza kwakufanele isetshenziselwe ukufaka imibala.
Ngokukhiqizwa kwefilimu yombala ye-PTFE yasekhaya kufinyelela esikalini esithile, ngokwenza ngcono inqubo, izinkomba zokusebenza zemikhiqizo ngokuvamile zifinyelela ezingeni lemikhiqizo efanayo yangaphandle.Kodwa-ke, okwamanje imikhiqizo yefilimu yombala ye-PTFE yasekhaya inokushiyeka okusobala kumqondo wombala nezinye izici zokubukeka, njengokusatshalaliswa okungalingani kwamabala ombala nezinye izinkinga.Ngokuthuthukiswa kobuchwepheshe obusha bokulungiselela ifilimu yombala we-PTFE kanye nokuthuthukiswa okuqhubekayo kwezidingo zokunqanda ilangabi labasebenzisi zezintambo nezintambo, ifilimu yefilimu ye-PTFE izintambo ezifakwe ifilimu kanye nezintambo zisetshenziswe kabanzi futhi kabanzi ezakhiweni eziphakeme kakhulu, izimoto, ikhompyutha. inethiwekhi yendawo, indlela ehamba ngaphansi nezinye izindawo ezingenalo izinga lokushisa eliphezulu.
Inqubo yokukhiqiza yefilimu yombala we-polytetrafluoroethylene:
(1) ukwelashwa kwangaphambili kwe-PTFE resin izinto zokusetshenziswa
I-PTFE imisiwe i-resin emihle yafakwa endaweni yokushisa engaguquki engu-20℃ ~ 23℃ amahora angu-24 ukuze kulungiswe kusengaphambili.
(2) ukwelashwa kwangaphambili kwezibala
Faka i-pigment ye-inorganic endishini yokomisa engu-2O℃ ~ 23℃ amahora angaphezu kwama-24 ukuze isetshenziswe.
(3) umbala
Inani elithile le-PTFE ehlanjululwe ngaphambilini emisiwe ye-resin yengezwe ku-rammer, futhi inani elithile le-pigment ye-inorganic ehlanjululwe ngaphambili yengezwa ukuze ixutshwe ngesivinini esikhulu ukuze kuhlakazwe umbala ngokulinganayo, futhi inhlaka yayikhululekile ukuze kube lula inqubo yokubumba. .
(4) isikhunta
Izinto ezidayiwe ze-PTFE ezicolekileyo zengezwe esibunjeni ngenqubo yokucindezela okubandayo, futhi inhlaka yempahla enemibala engu-40 000g PTFE yacindezelwa endaweni engenalutho emshinini we-othomathikhi wamathani angu-100 ku-2O MPa yokubumba ingcindezi eyodwa.Ngesikhathi sokucindezela, kwagxilwa ekukhipheni igesi ukuze kugwenywe ukuqhekeka kwezinto ezingenalutho.
(5) ukucula
Izocindezela umbungu omuhle wombala wokushisa okuphezulu kwesithando somlilo, ukushisa ngesilinganiso esingaba ngu-5 ℃ / ho kuya ku-330 ℃, ukugcinwa kokushisa, 3 h, bese ikhuphuka ngesilinganiso esingaba ngu-25 ℃ / h kuya ku-380 ℃, ukwahlukanisa 10 ~ Amahora angu-14, bese ukupholisa ngesilinganiso esingaba ngu-20 ~ 25 ℃ / h kuya ku-320 ℃, ukugcinwa kokushisa 3 ~ 4 h, ukupholisa kokugcina ngesilinganiso esingaba ngu-5 ℃ o/h kuya ku-15 ℃, o Vala imvelo kagesi ukupholisa ekamelweni lokushisa, ngaphandle kwemikhiqizo yombala.
(6) ukuphenduka ifilimu
Ama-preforms ahlanganisiwe wemikhiqizo yombala aguqulwa abe ama-preforms amafilimu amancane nge-lathe ekhethekile.Ulwelwesi olungenalutho luyi-0.1 mm×100 mm× lukhulu kuno-300 m(ubukhulu × ububanzi × ubude).
(7) ukuqondisa ngekhalenda
Umbala ongenalutho oqondile ngemva kokuphenduka ucutshungulwa yi-hot roll directional calender (bona FIG. 3) futhi iba yidigri eqondile engu-1.5 ~ 1.8, ugqinsi 0.05 mm semi-directional ifilimu, ukulawula izinga lokushisa kwe-hot roll cishe ku-100℃.
(8) ukusika
Masenze ukujiya kwefilimu yombala oyi-semi-directional engu-0.05 mm ngomshini wokusika okhethekile wokucubungula ube yifilimu yombala engu-0.PTFE eno-05 mm×90 mm× enkulu kuno-10m(ubukhulu × ububanzi × ubude).
(9) ukuhlolwa kokupakishwa
Ifilimu enemibala ye-PTFE ecutshunguliwe izothathwa ukuze ihlolwe ukusebenza kwangaphakathi, futhi ukubukeka nosayizi wefilimu kuzokwenziwa ngesikhathi esifanayo.Imikhiqizo efanelekayo izopakishwa ezikhwameni zefilimu ye-PVC nesitifiketi sokuhlola sinamathiselwe.
