Chifukwa Chiyani Mugwiritsire Ntchito Nsalu Zapamwamba za PTFE Monga Anti-Corrosion Lining? 4 Ubwino waukulu

M'mafakitale opangira mankhwala, zoyenga, ndi malo oyeretsera madzi oipa, zomangira zida zimakumana ndi nkhanza: ma asidi amphamvu, ma alkali otentha, zosungunulira za organic, ndi kutentha kwambiri. Zingwe za mphira zimatupa ndi kung'ambika. FRP linings matuza. Chitsulo chosapanga dzimbiri corrodes.

Nsalu ya PTFE yotentha kwambiri (PTFE-yokutidwa ndi fiberglass) imaposa zida zachikhalidwe izi. Ndi mankhwala olowera, osatentha, osasunthika, komanso osagwira - zonse pamodzi.

Aokai PTFE yapereka nsalu za PTFE zogwiritsira ntchito anti-corrosion lining kwazaka zambiri. Pansipa pali maubwino anayi, kuphatikiza zitsanzo zenizeni zenizeni.

Chemical Inertness - Imatsutsa Pafupifupi Chilichonse

Ubwino waukulu wa PTFE ndi kukana kwake kwachilengedwe konsekonse. Nthawi zambiri amatchedwa 'King of Plastics' pazifukwa zomveka.

1. Zomwe umakaniza

• Ma asidi amphamvu: Sulfuric, nitric, hydrochloric, phosphoric, ngakhale aqua regia (osakaniza a nitric ndi hydrochloric acid omwe amasungunula golide)

• Ma alkali amphamvu: sodium hydroxide, potaziyamu hydroxide, ammonia

• Zosungunulira za organic: Mowa, ma ketoni, ma hydrocarbon onunkhira (toluene, xylene), zosungunulira za chlorinated

• Zina zowononga: Oxidizers, salt, ndi mankhwala ambiri amakampani

2. Zomwe sichingakane (zochepa)

• Zitsulo zosungunuka za alkali (sodium, potaziyamu) - zidzawononga PTFE

• Mpweya wa fluorine ndi othandizira amphamvu a fluorinating pa kutentha kwakukulu

• Hydrofluoric acid (HF) - imaukira gawo lapansi la fiberglass ngati zokutira zili ndi mapini

Chidziwitso chothandiza: Pantchito ya hydrofluoric acid, gwiritsani ntchito kalasi yapadera yosamva HF kapena onetsetsani kuti zokutira za PTFE zilibe pinhole (zodutsa zokutira zingapo). Aokai PTFE imapereka magiredi otere.

Kutentha Kwambiri Kwambiri - Kuyambira Kuzizira mpaka Kutentha Kwambiri

Anti-corrosion linings nthawi zambiri amakumana osati ndi mankhwala, koma kutentha kwambiri. Nsalu ya PTFE imagwira malekezero onse a sipekitiramu.

1. Kutentha kwapamwamba

• Kutentha kosalekeza kogwira ntchito: -70°C mpaka 260°C

• Kutalika kwanthawi yayitali: 350 ° C (maulendo achidule)

• Kuyeza kukalamba kwa kutentha: Pambuyo pa masiku 200 mosalekeza pa 250 ° C, mphamvu zamakina siziwonetsa kutsika koonekeratu.

2. Kuchita kwa kutentha kochepa

• Imasinthasintha mpaka -70 ° C

• Imatha kupirira -180 ° C (kutentha kwa nayitrogeni wamadzimadzi) popanda kusweka - ngakhale kusinthasintha kumachepetsedwa

3. Chifukwa chiyani izi ndizofunikira pakugwiritsa ntchito lining

Mu zida za desulfurization, gasi wa flue amatha kufika 200-250 ° C. Zingwe za mphira zimatsika pamwamba pa 120 ° C. Nsalu ya PTFE imayenda bwino. Mu cryogenic chemical processing (-50 ° C), PTFE sikhala yolimba ngati mapulasitiki ambiri.

Katundu Wakuthupi ndi Wamakina - Wokhazikika, Wamphamvu, komanso Wopanda Ndodo

Kupitilira kukana kwamankhwala ndi matenthedwe, nsalu ya PTFE imapereka maubwino angapo amakina omwe amapangitsa kuti ikhale yabwino kwambiri.

1. Dimensional bata (otsika mapindikidwe)

Gawo la fiberglass gawo lapansi limapatsa PTFE nsalu yolimba kwambiri komanso yotsika kwambiri - nthawi zambiri imakhala <0.5% pansi pa katundu. Izi zikutanthauza:

• Mzerewu sutambasuka kapena kufota pakapita nthawi

• Palibe makwinya kapena makwinya chifukwa chakukula kwa matenthedwe

• Imasunga zolimba motsutsana ndi khoma la zida

2. Pansi yopanda ndodo (kuyeretsa kosavuta)

PTFE's friction coefficient ndi yotsika ngati 0.05-0.1 . Zinthu zambiri sizingathe kumamatira pamwamba pake. Kwa anti-corrosion linings, izi zikutanthauza:

• Zotsalira za zochita za mankhwala sizimangirira pamzere

• Kuyeretsa pakati pa magulu ndikofulumira - nthawi zambiri kumangotsuka madzi

• Palibe 'kuwotcha pa' ma depositi amankhwala owuma

3. Kutsekemera kwamagetsi

• Dielectric nthawi zonse <2.6

• Kulephera kwa voliyumu yayikulu (>10⊃1;⁵ Ω·cm)

• Oyenera insulating wraps mu zipangizo zamagetsi ndi magetsi kumene dzimbiri chitetezo kumafunikanso

4. Anti-kukalamba ndi retardant lawi

• Kukaniza kwanyengo (kukhazikika kwa UV)

• Zosayaka - kuzimitsa zokha (UL94 V-0 mlingo wamba)

• Palibe kuwonongeka koyezera pambuyo pazaka zambiri zakunja

Chitsimikizo Chamgulu la Chakudya - Otetezeka Chakudya ndi Pharma

Sikuti zomangira zonse zotsutsana ndi dzimbiri ziyenera kukhala zapamwamba. Koma akatero - pokonza chakudya, mankhwala, kapena madzi amchere - nsalu za PTFE zimapereka.

1. Zitsimikizo

• FDA 21 CFR 177.1550 - yokhudzana ndi chakudya chachindunji komanso chosalunjika

• EU Regulation 1935/2004 - pazolumikizana ndi chakudya

• Zopanda poizoni, zopanda fungo ngakhale kutentha kwambiri

• Palibe kutulutsa zinthu zovulaza m'zakudya kapena m'zamankhwala

2. Kumene kumagwiritsiridwa ntchito mizere ya chakudya

• Mapepala ophika ndi zomangira za uvuni m'mabuki amalonda (opanda ndodo, kuyeretsa kosavuta)

• Zida zopangira mankhwala - zotengera zochitira ndi ma tray owumitsa

• Matanki opangira chakudya - pomwe zakudya za asidi kapena zamafuta zimalumikizana ndi mkanda

Zofananira Zogwiritsa Ntchito Pa Anti-Corrosion Lining

Kutengera zabwino zomwe tafotokozazi, PTFE nsalu yotentha kwambiri imagwiritsidwa ntchito kwambiri m'magawo awa:

1. Chitetezo cha mankhwala ndi chilengedwe

• Mapaipi a petrochemical - chitsulo chamkati kuti chiteteze dzimbiri kumafuta amafuta, zinthu zoyengedwa, ndi mpweya wowawasa

• Zida zochotsera sulfurization (zopangira magetsi) - zopangira zoyakira, ma ductwork, ndi ma chimney pomwe mpweya wa flue uli ndi SOₓ ndi HCl

• Zotengera zochitira ndi akasinja osungira - zomangira akasinja okhala ndi zidulo, ma alkali, kapena zosungunulira zaukali

• Matanki onyamula zitsulo - zomangira akasinja okhala ndi hydrochloric kapena sulfuric acid poyeretsa zitsulo

Zambiri zakumunda zochokera ku Aokai PTFE: Mu nsanja yopangira mphamvu zamagetsi, PTFE nsalu idakhala zaka 3 popanda kulephera. Kuyika mphira m'mbuyomu kunatenga miyezi 9 yokha. Ndiko kukulitsa moyo wa 4x.

2. Makampani opanga zakudya ndi mankhwala

• Mapepala ophika ndi zomangira mu uvuni - zosamata, zoyera zosavuta, zovomerezeka ndi FDA

• Ma microwave gaskets - osagwira kutentha komanso osagwira

• Zida zopangira mankhwala - zomangira zowumitsa thireyi, zosakaniza zosakaniza, ndi zomatira mapiritsi

3. Makina ndi zamagetsi

• Malamba onyamula kutentha kwambiri kwa ma photovoltaic laminators - amaphatikiza anti-corrosion ndi osagwira ndodo komanso kukana kutentha.

• Ma mbale osindikizira otentha - Nsalu ya PTFE ngati chivundikiro chopanda ndodo

• Zotchingira zotchingira magetsi - pomwe zotchingira ndi dzimbiri zimafunikira

Mwachidule - Chifukwa Chosankha PTFE Nsalu ya Anti-Corrosion Lining

Aokai PTFE imapanga nsalu zotentha kwambiri za PTFE makamaka zopangira anti-corrosion lining application. Timapereka m'lifupi mwake, makulidwe (0.08mm mpaka 0.40mm), ndi magiredi ovomerezeka a FDA. Lumikizanani nafe ndi malo omwe mumakhala nawo, kutentha, ndi kukula kwa zida kuti tikudziwitseni.

Zomwe zili pamwambazi zimaperekedwa ndi Malingaliro a kampani Jiangsu Aokai New Materials Technology Co., Ltd.

Ngati mukufuna kudziwa zambiri zatsatanetsatane, zochitika zamagwiritsidwe ntchito ndi mayankho makonda pazogulitsa zathu zonse, kuphatikiza nsalu za PTFE zotentha kwambiri, matepi a PTFE, malamba a mesh a PTFE, malamba omangira makina opanda msoko, nsalu ya PTFE ya mbali imodzi, zosagwira kutentha kwambiri, zosagwirana ndi magalasi ofunda, chonde osamva magalasi osasunthika. ife:

• Bambo Guo: +86 18944819998

• Bambo Liu: + 86 13705266308

Nthawi zonse timatsatira filosofi ya ukatswiri ndi kukhulupirika, ndipo tadzipereka kukupatsani mayankho amodzi ndi ntchito zolingalira.
