N’chifukwa chiyani imatchedwa ptfe tube? Kodi imatchedwa bwanji ptfe tube?
Chubu cha polytetrafluoroethylene chimatchedwansoChubu cha PTFE, yomwe imadziwika kuti "Plastic King", ndi polima ya molekyulu yambiri yokonzedwa ndi tetrafluoroethylene yopangidwa ndi polymerizing ngati monomer. Yoyera ngati sera, yowala, yolimba kwambiri kutentha ndi kuzizira, ingagwiritsidwe ntchito kwa nthawi yayitali pa -180 ~ 260ºC. Zinthuzi zilibe utoto kapena zowonjezera, zimakhala ndi mawonekedwe otsutsana ndi asidi, alkali, ndi zinthu zosiyanasiyana zachilengedwe, ndipo sizisungunuka kwambiri mu zinthu zonse zosungunulira. Nthawi yomweyo, PTFE ili ndi mawonekedwe otsutsana ndi kutentha kwambiri, ndipo coefficient yake yokangana ndi yotsika kwambiri, kotero ingagwiritsidwe ntchito popaka mafuta ndikukhala chophimba chabwino kwambiri chotsukira mosavuta mkati mwa mapaipi amadzi.
Njira yopangira:
Zipangizo zopangira za chubu cha PTFE zimakhala ndi ufa ndipo zimatha kupangidwa ndi kuponderezedwa kapena kuchotsedwa kwa madzi.
Mtundu wa chubu:
1. Chitoliro chosalala chimapangidwa ndi utomoni wa PTFE wa 100% wopanda pigment kapena zowonjezera. Ndi choyenera kugwiritsidwa ntchito mu Aerospace & Transportation Technology, Electronics, Components & Insulators, Chemical & Pharmaceutical Manufacturing, Food Processing, Environmental Sciences, Air Sampling, Fluid Transfer Devices ndi Water Processing Systems. Pali mitundu ya machubu onse oletsa kusinthasintha (Carton) kapena mitundu ina.
2. Machubu opindika amapangidwa ndi utomoni wa PTFE wa 100% wopanda pigment kapena zowonjezera. Uli ndi kukana kosinthasintha komanso kolimba bwino kuti ugwire bwino ntchito ngati pakufunika kupindika kolimba, kukanikiza kwambiri kapena kukanikiza. Machubu opindika amatha kupezeka ndi ma flares, ma flanges, ma cuffs, kapena kuphatikiza kwa machubu opitilira amodzi. Pali mitundu yosiyanasiyana ya machubu otsutsana ndi mpweya (carbon) omwe amapezeka.
3. Machubu a Capillary Makhalidwe a kutentha ndi kukana dzimbiri kwa machubu a capillary akhala akugwiritsidwa ntchito kwambiri m'mafakitale okana dzimbiri, monga makampani opanga mankhwala, pickling, electroplating, mankhwala, anodizing ndi mafakitale ena. Chubu cha capillary chimakhala ndi kukana dzimbiri kwabwino, kukana kuipitsa, kukana kukalamba, kukana kutentha kwabwino, kukana pang'ono, kukula kochepa, kulemera kopepuka komanso kapangidwe kakang'ono.
Katundu ndi kukhazikika:
1. Kukana kutentha kwambiri, kosasungunuka mu zosungunulira zilizonse. Imatha kupirira kutentha kwambiri mpaka 300℃ munthawi yochepa, ndipo ingagwiritsidwe ntchito mosalekeza pakati pa 240℃ ~ 260℃, ndipo imakhala ndi kutentha kolimba kwambiri. Kuwonjezera pa kuchitapo kanthu ndi zitsulo zosungunuka za alkali, siidzawonongeka ndi chinthu chilichonse, ngakhale itawiritsidwa mu hydrofluoric acid, aqua regia kapena fuming sulfuric acid, sodium hydroxide, sidzasintha.
2. Kukana kutentha kochepa, kulimba kwa makina abwino pa kutentha kochepa, ngakhale kutentha kutsika kufika -196 ℃ popanda kuphulika, kumatha kusunga kutalika kwa 5%.
3. Kukana dzimbiri, kusagwirizana ndi mankhwala ambiri ndi zosungunulira, kusagwirizana ndi ma asidi amphamvu ndi alkali, madzi ndi zosungunulira zosiyanasiyana zachilengedwe, ndipo zimatha kuteteza ziwalo ku dzimbiri la mankhwala aliwonse.
4. Yoletsa kukalamba, ikalemera kwambiri, ili ndi ubwino wowirikiza wa kusakalamba komanso kusamamatira. Ili ndi moyo wabwino kwambiri wokalamba mu pulasitiki.
5. Mafuta ambiri, omwe ndi otsika kwambiri pakati pa zinthu zolimba. Mafuta ochulukirapo amasintha pamene katundu akutsetsereka, koma mtengo wake ndi pakati pa 0.05-0.15.
6. Chosamamatira, chomwe chili ndi mphamvu yochepa kwambiri pakati pa zinthu zolimba, ndipo sichimamatira ku chinthu chilichonse. Pafupifupi zinthu zonse sizimamatira. Mafilimu opyapyala kwambiri amasonyezanso makhalidwe abwino osamamatira.
7. Ndi yoyera, yopanda fungo, yopanda kukoma, yopanda poizoni, komanso yopanda mphamvu m'thupi. Monga mtsempha wamagazi wopangidwa ndi thupi komanso chiwalo chomwe chimayikidwa m'thupi kwa nthawi yayitali, sichikhala ndi zotsatirapo zoyipa.
8. Kulemera kopepuka komanso kusinthasintha kwamphamvu. Zingachepetse kwambiri mphamvu yogwirira ntchito ya wogwiritsa ntchito.
9. Ubwino wonse wa mankhwalawa, kotero kuti moyo wautumiki ndi woposa mitundu yosiyanasiyana ya payipi ya nthunzi yomwe ilipo, kugwiritsa ntchito kwa nthawi yayitali sikuyenera kusinthidwa, kuchepetsa kwambiri ndalama zogwiritsira ntchito, kukonza magwiridwe antchito, ndalama komanso zothandiza.
Madera ogwiritsira ntchito:
Amagwiritsidwa ntchito mumakampani amagetsi
Mu ndege, ndege, zamagetsi, zida, makompyuta ndi mafakitale ena monga gawo lotetezera mphamvu ndi mizere yazizindikiro, zipangizo zosagwira dzimbiri komanso zosatha ntchito zingagwiritsidwe ntchito popanga mafilimu, mapepala a chubu, mabearing, ma washer, ma valve ndi mapaipi a mankhwala, zolumikizira mapaipi, zolumikizira zotengera zida, ndi zina zotero.
Amagwiritsidwa ntchito m'minda ya zida zamagetsi
makampani opanga mankhwala, ndege, makina, ndi zina zotero m'malo mwa magalasi a quartz, omwe amagwiritsidwa ntchito pofufuza mankhwala oyera kwambiri komanso kusunga ma acid osiyanasiyana, alkali, ndi zinthu zosungunulira zachilengedwe mu mphamvu ya atomiki, mankhwala, semiconductor ndi mafakitale ena. Itha kupangidwa kukhala zida zamagetsi zoteteza kutentha kwambiri, waya wothamanga kwambiri ndi zingwe zotchingira, zida za mankhwala zosagwira dzimbiri, mapaipi amafuta ozizira kwambiri, ziwalo zopangira, ndi zina zotero. Zingagwiritsidwe ntchito ngati zowonjezera pa pulasitiki, rabara, zokutira, inki, mafuta odzola, ndi zina zotero.
Chogulitsachi chimapirira kutentha kwambiri komanso dzimbiri
Ili ndi mphamvu yabwino kwambiri yotetezera magetsi, yolimba, yonyowa madzi pang'ono, komanso yodzipaka mafuta bwino. Ndi ufa wopaka mafuta womwe umagwiritsidwa ntchito popanga zinthu zosiyanasiyana ndipo ungagwiritsidwe ntchito mwachangu kupanga filimu youma. Imagwiritsidwa ntchito m'malo mwa graphite, molybdenum ndi mafuta ena osapangidwa. Ndi chotulutsira nkhungu choyenera ma polima a thermoplastic ndi thermosetting okhala ndi mphamvu yabwino kwambiri yonyamula. Imagwiritsidwa ntchito kwambiri mumakampani opanga elastomer ndi rabara komanso anti-corrosion.
Amagwiritsidwa ntchito ngati chodzaza cha utomoni wa epoxy kuti awonjezere kukana kutopa, kukana kutentha komanso kukana dzimbiri kwa zomatira za epoxy
Amagwiritsidwa ntchito makamaka ngati chomangira ndi chodzaza makeke a ufa
Kusaka kokhudzana ndi machubu a PTFE:
