Ifilimu yombala we-PTFE luhlobo olutsha lwe-c-grade insulation material kunye nokusebenza okugqwesileyo okugqibeleleyo, okufanelekile kwiimfuno ezizodwa, njengezixhobo zombane eziphawulwe ngombala okanye ngocingo lokugquma, njl. ishishini kunye nesayensi yombane kunye neteknoloji.
Ifilimu yombala we-PTFEluhlobo olutsha lwemathiriyeli yokugquma i-c-grade esebenza ngokugqwesileyo, efanelekile kwiimfuno ezizodwa, njengezixhobo zombane eziphawulwe ngombala okanye ngocingo lokugquma, njl. -inzululwazi ye-elektroniki kunye nethekhinoloji.Kwisicelo sokuqala se-PTFE iplastiki ye-insulated wire kunye nekhebula, yayikhawulelwe kuphela kwi-wiring yangaphakathi kunye ne-lead yocingo lwezixhobo zombane kunye ne-elektroniki kwindawo yobushushu obuphezulu beenqwelo-moya, iinqanawa kunye namanye amagumbi eenjini kwindawo yomkhosi.Ngokukhuthazwa kobugcisa bokulungiselela, i-PTFE iye yandiswa ngokuthe ngcembe kwimigca yokufakela izixhobo zombane kunye nezixhobo zombane kwindawo yobushushu obuphezulu.Ngaphambili, iifilimu ze-PTFE zasekhaya beziyimibala yendalo yezixhobo (kuba iifilimu ze-PTFE akulula ukuba zibe nemibala).Ukwenzela ukwahlula imigca engenayo nephumayo yemiqondiso eyahlukeneyo yothumelo kunye nokwenza kube lula ukwahlula, indlela yokwaleka kwafuneka isetyenziselwe ukufaka imibala.
Ngemveliso yefilimu ye-PTFE yasekhaya ifikelela kwinqanaba elithile, ngokuphucula inkqubo, izalathisi zokusebenza kweemveliso ubukhulu becala zifikelela kwinqanaba leemveliso ezifanayo zangaphandle.Nangona kunjalo, okwangoku iimveliso zefilimu zasekhaya ze-PTFE zineziphene ezicacileyo kwingqiqo yombala kunye neminye imiba yenkangeleko, njengokusasazwa ngokungalingani kwamabala ombala kunye nezinye iingxaki.Ngophuhliso lweteknoloji entsha yokulungiselela ifilimu ye-PTFE kunye nokuphuculwa okuqhubekayo kweemfuno ze-flame retardant zabasebenzisi kwiingcingo kunye neentambo, ifilimu ye-PTFE ifilimu efakwe ifilimu kunye neentambo ziye zasetyenziswa ngokubanzi ngakumbi kwizakhiwo eziphakamileyo, iimoto, ikhompyutha. uthungelwano lwendawo yendawo, umzila ongaphantsi komhlaba kunye nezinye iindawo ezingezizo zobushushu obuphezulu.
Inkqubo yokuvelisa ifilimu yombala we-polytetrafluoroethylene:
(1) ukunyangwa kwangaphambili kwe-PTFE resin imathiriyeli ekrwada
I-PTFE inqunyanyisiwe intlaka entle yafakwa kwi-greenhouse engaguqukiyo kwi-20℃ ~ 23℃ iiyure ezingama-24 zonyango lwangaphambili.
(2) ukunyangwa kwangaphambili kwee-pigments
Beka i-pigment ye-inorganic kwisitya sokumisa se-2O℃ ~ 23℃ ngaphezulu kweeyure ezingama-24 eziza kusetyenziswa.
(3) umbala
Ubungakanani obuthile be-PTFE echongiweyo yangaphambili i-resin entle yongezwa kwi-rammer, kwaye inani elithile le-pigment ye-inorganic pre-treated yongezwa ukuxuba ngesantya esiphezulu ukusasaza i-pigment ngokulinganayo, kwaye i-resin yayikhululekile ukuququzelela inkqubo yokubumba. .
(4) ngundo
Izinto ezidayiweyo ze-PTFE ezicolekileyo zongezwa kwi-mold yinkqubo yokucofa okubandayo, kwaye i-40 000g PTFE ye-resin ecolekileyo enemibala ecolekileyo yacinezelwa kwindawo engenanto kwi-100 yetoni yoxinzelelo oluzenzekelayo kumatshini kwi-2O MPa yokubumba uxinzelelo olulodwa.Ngethuba lokucinezela, ingqalelo yahlawulwa ekukhupheni igesi ukuphepha ukuqhekeka kwezinto ezingenanto.
(5) ukucula
Uya kucinezela i-embryo enemibala emihle yobushushu obuphezulu be-sintering, ukufudumeza ngesantya esimalunga ne-5 ℃ / ho ukuya kwi-330 ℃, ukugcinwa kobushushu, i-3 h, emva koko inyuke ngesantya esimalunga ne-25 ℃ / h ukuya malunga ne-380 ℃, ukugquma i-10 ~ 14 h, kwaye ke ukupholisa ngesantya malunga 20 ~ 25 ℃ / h ukuya 320 ℃, ukugcinwa ubushushu 3 ~ 4 h, ukupholisa lokugqibela ngesantya malunga 5 ℃ o/h ukuya 15 ℃, o Vala zombane zendalo. ukupholisa kwiqondo lokushisa, ngaphandle kweemveliso zombala.
(6) ukujika ube yifilimu
I-sintered preforms yeemveliso zombala ziguqulwa zibe yifilim ecekethekileyo preforms ngelathe ekhethekileyo.I-membrane engenanto yi-0.1 mm×100 mm× enkulu kune-300 m (ubukhulu × ububanzi × ubude).
(7) ukuqhelaniswa nekhalenda
Umbala wesalathiso ongenanto emva kokujika ucutshungulwa yi-calender ye-hot roll directional (jonga i-FIG. 3) kwaye iba yi-degreeal degree ye-1.5 ~ 1.8, ubukhulu be-0.05 mm ifilimu ye-semi-directional, ulawulo olushushu lobushushu malunga ne-100 ℃.
(8) ukucheba
Masenze ubungqingqwa befilimu yombala oyi-0.05 mm esi-directional ngomatshini okhethekileyo wokucutshungulwa kwifilimu yombala we-0.PTFE ene-05 mm×90 mm× enkulu kuno-10m(ukutyeba × ububanzi × ubude).
(9) ukuhlolwa kokupakishwa
Ifilimu enemibala ye-PTFE ecutshungulwayo iya kwenziwa isampula ukuze ihlolwe ukusebenza kwangaphakathi, kunye nokuhlolwa kwembonakalo kunye nobukhulu befilimu kuya kuqhutywa ngaxeshanye.Iimveliso ezifanelekileyo ziya kupakishwa kwiingxowa zefilimu zePVC kunye nesatifikethi sokuhlola esiqhotyoshelweyo.
