Funsani

Ingoganizirani kugwiritsa ntchito PTFE tepi yotentha kwambiri mu thanki yamankhwala, chokulunga chingwe cha m'madzi, kapena chosindikizira chapansi pa madzi. Tepiyo imamira kwa milungu kapena miyezi. Kodi chidzagwira? Kodi zomatira zidzalephera? Kodi fiberglass idzafewetsa?

Yankho si lophweka. PTFE palokha - 'King of Plastics' - imalowa m'thupi ku pafupifupi zinthu zonse. Koma tepi ya PTFE ndiyoposa PTFE yokha: ili ndi gawo lapansi la fiberglass ndi zomatira zovutirapo (PSA) kumbuyo. Zigawozi zimakhala zosiyana kwambiri pansi pa kumizidwa kwa nthawi yaitali.

Aokai PTFE yayesa ma tepi ambiri m'mikhalidwe yomiza. Nkhaniyi ikufotokoza za kuopsa kwa madzi, madzi amchere, ndi mankhwala - ndikufotokozera mitundu ya zomatira zomwe zimakhalapo.

Mfundo Yonse - Gawo la PTFE Ndilolimba, Zomatira Ndi Zofooka

Kwa matepi otentha kwambiri a PTFE pansi pa kumizidwa kwa nthawi yayitali, ntchito yonseyo ikhoza kufotokozedwa mwachidule monga:

Zida zoyambira za PTFE: Zabwino kwambiri - zopanda mankhwala, zosagwira, zokhazikika.
Fiberglass substrate: Yowopsa - imatha kufewetsa m'madzi kwa nthawi yayitali.
Zomatira zomatira: Malo ofooka kwambiri - amawonongeka akakumana ndi madzi kwa nthawi yayitali, zosungunulira, kapena mankhwala.

Chigawo	Kuchita Pansi pa Kumizidwa	Kulephera Mode
PTFE zokutira	Zabwino kwambiri	Palibe - amakhalabe wopanda pake
Nsalu za fiberglass	Wapakati	Kufewetsa, kutaya mphamvu pambuyo pa masabata/miyezi
Silicone PSA	Zabwino kwa osauka	Kutaya kwa adhesion, kutupa, peeling
Acrylic PSA	Osauka kwambiri	Kuwonongeka kofulumira m'madzi / zosungunulira

Kuopsa kwa Kumizidwa M'madzi Kwanthawi Yaitali

Momwe madzi amakhudzira tepi:

Zomatira zomatira: Zomatira zomata za silicone zimafooka chifukwa chokhala ndi mamolekyu amadzi kwa nthawi yayitali. Madzi amalowa m'malo omatira-gawo, amachepetsa kumamatira ndipo pamapeto pake amachititsa kulephera kwathunthu. Mphamvu ya peel imatha kutsika mpaka 40% pakatha maola 48 akumizidwa m'madzi pakupanga zina.
Fiberglass gawo lapansi: Matepi ambiri amalonda a PTFE otentha kwambiri amagwiritsa ntchito nsalu ya fiberglass yokhala ndi PTFE ngati gawo lapansi. Fiberglass idzafewetsa m'madzi kwa nthawi yayitali, zomwe zimapangitsa kuchepa kwa mphamvu yamakina onse a tepi. Iyi ndi njira yapang'onopang'ono (masabata mpaka miyezi) koma yosasinthika.

Ndi liti pamene kumizidwa m'madzi ndikovomerezeka?

Kulumikizana kwakanthawi kochepa (kutsuka, kuwaza, kuyeretsa mwachidule) - chabwino.
Kumiza mosalekeza kwa masiku kapena masabata - osavomerezeka pamatepi wamba a silicone PSA.
Kuti mugwiritse ntchito pansi pamadzi kosatha, ganizirani tepi ya PTFE yopanda zomatira yokhala ndi makina okhazikika.

Aokai PTFE imalangiza makasitomala kuti tepi yokhazikika ya silikoni ya PSA ndiyoyenera kugwiritsa ntchito polumikizana ndi madzi nthawi ndi nthawi (mwachitsanzo, malo opangira chakudya) koma osati kumizidwa mosalekeza kupitilira maola 72. Kwa nthawi yayitali, timalimbikitsa zomatira za fluorosilicone kapena magiredi opanda zomatira.

Kumizidwa m'madzi amchere - Kuwopsa Kwambiri

Poyerekeza ndi madzi oyera, madzi amchere amawopsa kwambiri:

Chloride ayoni imathandizira kulowa ndikuwonongeka kwa zomatira.
Madzi amchere amachititsa dzimbiri kwambiri ku fiberglass substrates - ulusi wagalasi ukhoza kutsika ndikufowoka.
Mchere crystallization pa kuyanika m'zinthu akhoza umakaniko kusokoneza zomatira chomangira.

Malangizo: Osagwiritsa ntchito tepi yokhazikika ya PTFE kumizidwa kwanthawi yayitali m'madzi amchere (mwachitsanzo, zomata chingwe cha m'madzi, masensa apansi pamadzi). Gwiritsani ntchito zomatira za perfluoropolyether (PFPE) kapena PTFE yopanda zomatira yokhala ndi makina omangira.

Kumizidwa kwa Chemical Solution - Kumatengera Zomatira

Matepi a PTFE amapambana pakukana kwamankhwala - koma izi zimatengera mtundu wa zomatira. Kuopsa komizidwa ndi mankhwala kumasiyana kwambiri.

Mtundu Womatira	Kukaniza Chemical	Malangizo a Ntchito
Acrylic PSA	Zosauka - zosagonjetsedwa ndi asidi amphamvu, alkalis amphamvu, kapena zosungunulira zambiri za organic	Ndi zoletsedwa kumiza mankhwala aliwonse
Conventional Silicone PSA (zambiri)	Zochepa - zimakana madzi, zidulo zofooka, ma alkali ofooka, ndi zosungunulira zina. Amalephera kumizidwa kwa nthawi yayitali mu ma acid amphamvu, ma alkali amphamvu, ndi zosungunulira za polar (mwachitsanzo, acetone, MEK)	Zoyenera kokha pachitetezo chopepuka chamankhwala - osati kumizidwa mosalekeza
Fluorosilicone Modified PSA	Zabwino - zapamwamba kwambiri kuposa silikoni wamba pakukana mankhwala; imapirira kumizidwa kwakanthawi kochepa	Ndikoyenera kumizidwa kwanthawi yayitali (masiku mpaka masabata) komanso zotsutsana ndi dzimbiri
Perfluoropolyether / Fluorine-based Adhesive	Zabwino kwambiri - zimagwirizana ndi kukana kwamankhwala kwa gawo lapansi la PTFE; osakhudzidwa kwambiri ndi mankhwala wamba	Zokondedwa m'malo owononga kwambiri komanso kumizidwa kwanthawi yayitali (miyezi). Mtengo wapamwamba.
Tepi Yoyera ya PTFE (Palibe Zomatira)	Wapamwamba - palibe zolakwika zokhudzana ndi zomatira; Kukana kwamankhwala kofanana ndi gawo lapansi la PTFE	Chisankho chapamwamba cha kumizidwa kwamadzimadzi. Pamafunika kukonza makina (kusindikiza ulusi, kutsekereza bawuti, kumanga waya)

Kuwonongeka Kwamagwiridwe Kwathupi - Zofunikira Zofunikira

Katundu	Gawo la PTFE	Zomatira Layer	Zolemba
Peel Mphamvu	N / A	Itha kutsika mpaka 40% pambuyo pa kumizidwa m'madzi kwa maola 48 (kwa PSA yochiritsika ndi UV)	Chizindikiro chachikulu cha kulephera kwa tepi
Kulimba kwamakokedwe	Palibe kutaya pambuyo pa masiku 200 pa 250 ° C	N / A	Ma CF bond amapereka kukhazikika kwapadera
Kutupa	Palibe - ngakhale mu 98% H₂SO₄ kapena 40% HF	Kutupa mu zosungunulira (toluene, acetone, MEK)	Kutupa kwa zomatira kumabweretsa kukweza m'mphepete
Kukaniza kwa Corrosion	> 95% mphamvu zamakokedwe zimasungidwa pambuyo pa 168h pakuwira 37% HCl	Zimasiyanasiyana ndi mtundu	Fiberglass imatha kuukiridwa ndi HF ndi maziko amphamvu
Magetsi Insulation	Wodalirika	Kuwonongeka kungachepetse mphamvu ya dielectric	Sankhani zinthu zomwe zikukwaniritsa zofunikira zotchinjiriza

Chotengera chofunikira: Gawo la PTFE ndilokhazikika modabwitsa. Pafupifupi zoopsa zonse zowonongeka zimachokera ku zomatira ndipo, pang'ono, gawo lapansi la fiberglass.

Chidule cha Maupangiri ndi Zosankha Zogwiritsa Ntchito Kumiza

Kumizidwa chilengedwe	Mtundu wa Tepi Wovomerezeka	Chifukwa chiyani?
Madzi ozizira, osasunthika	Standard silikoni PSA	Zovomerezeka zopopera, zochapira
Madzi abwino, mosalekeza (> masiku 7)	Fluorosilicone PSA kapena zomatira	Standard silikoni adzataya adhesion
Madzi amchere, nthawi iliyonse	PTFE yopanda zomatira + makina kukonza	Mchere umawononga zomatira komanso fiberglass
Ma acid / maziko ofooka (pH 4-10), pafupipafupi	Standard silikoni PSA	Zovomerezeka
Amphamvu zidulo / maziko, organic solvents, mosalekeza	PTFE yopanda zomatira (mawotchi fixation) kapena zomatira za PFPE	Ndi amenewa okha amene amapulumuka
Kumizidwa kotentha kwambiri (>150°C)	Silicone kapena fluorosilicone PSA	Acrylic amalephera; PTFE gawo lapansi lili bwino

Mwachidule , tepi ya PTFE yotentha kwambiri imatha kugwiritsidwa ntchito pomiza - koma pokhapokha ngati mumvetsetsa mfundo zofooka. Gawo la PTFE silingagonjetsedwe. Fiberglass ili pachiwopsezo chambiri. Zomatira ndiye chiopsezo chachikulu cholephera.

Kumizidwa m'madzi mwatsopano pansi pa maola 72, silicone PSA yovomerezeka ndiyovomerezeka. Kwa nthawi yayitali, madzi amchere, kapena mankhwala owopsa, sinthani kukhala fluorosilicone, zomatira za PFPE, kapena - koposa zonse - tepi ya PTFE yopanda zomatira yokhala ndi makina amakina.

Mukufuna tepi ya PTFE ya malo enieni omiza? Aokai PTFE imapereka zosankha zingapo zomatira ndipo imatha kukupatsirani data yoyeserera pamikhalidwe yanu. Lumikizanani nafe ndi sing'anga, kutentha, ndi nthawi yomizidwa yomwe mukuyembekezera.

Izi zimaperekedwa ndi Malingaliro a kampani Jiangsu Aokai New Materials Technology Co., Ltd.

Ngati mukufuna tsatanetsatane, malangizo ogwiritsira ntchito, ndi njira zothetsera makonda amtundu wathu wonse, kuphatikizapo nsalu za PTFE zotentha kwambiri, matepi a PTFE, malamba a PTFE, malamba osakanizika, makina osakanikirana a PTFE, nsalu zotchinga za PTFE, malamba oyendetsa kutentha kwambiri ndi kutentha kwambiri , chonde lemberani magalasi a fiberglass:
