Fabric mai rufi PTFE -
gyare na PTFE? Ta yaya aikin sa ya kwatanta da maganin corona da maganin plasma?
Za a iya amfani da fasahar jiyya na harshen wuta don gyaran gyare-gyare na PTFE? Ta yaya aikin sa ya kwatanta da maganin corona da maganin plasma?
Aiwatar da Masana'antu: A ka'ida, maganin harshen wuta na iya gane gyaran fuska na PTFE. Koyaya, ba kasafai ake karbe shi ta masana'antu ba, kuma tasirinsa ya yi kasa da maganin plasma. PTFE masana'antun masana'anta masu zafi masu zafi ba su ba da shawarar shi azaman hanyar al'ada ba.
Hatsarin Tsaro: PTFE yana da saurin bazuwar thermal a ƙarƙashin zafi mai zafi, yana fitar da iskar gas mai guba kamar hydrogen fluoride da perfluoroisobutylene, waɗanda ke haifar da haɗari mai tsanani ga ma'aikata da muhalli. Matakan kariya sun zama wajibi.
Ƙayyadaddun Ayyuka: Ko da a ƙarƙashin madaidaicin iko, oxidation na harshen wuta zai iya tayar da makamashi na PTFE kawai daga 18 mN / m zuwa 30-35 mN / m. Lalacewar thermal a saman cikin sauƙi yana samar da ƙarancin iyaka mai rauni, yana haifar da ƙarancin haɓaka aikin mannewa.
II. Kwatanta Hanyoyin Aiki na Tsari Uku
Jiyya na harshen wuta: Dogaro da iskar oxygen mai zafi sama da 1000 ° C daga harshen wuta, yana samun ɗan ƙarami kuma yana gabatar da ƙaramin adadin ƙungiyoyi masu ɗauke da iskar oxygen, duk da haka yana nuna rashin ƙarfi a cikin karya bargawar C-F.
Maganin Corona: Fitar da wutar lantarki mai ƙarfi yana haifar da ozone da iskar oxygen mai aiki, yana haɗa bam na jiki tare da ƙarancin iskar shaka. Saboda ƙarancin ƙarfin kuzari, da kyar yake karya tsayayyen haɗin C-F.
Jiyya na Plasma: Barbashi mai ƙarfi, electrons da radicals masu kyauta kai tsaye suna manne C-F bonds, da ƙungiyoyin polar polar kamar su hydroxyl, carboxyl da ƙungiyoyin amino don cimma aikin grafting sinadarai, suna isar da mafi zurfin gyare-gyare.
III. Bambance-bambance a Maɓallin Ayyukan Ayyuka
Surface Energy and Adhesion Strength: Low-pressure oxygen plasma can lift PTFE surface energy to 50–65 mN/m with adhesion strength reaching 8–15 MPa. Maganin harshen wuta da corona kawai suna haɓaka ƙarfin sama zuwa 30-38 mN/m, kuma ƙarfin mannewa gabaɗaya ya fi 2 MPa, galibi yana tare da gazawar tsaka-tsaki.
Uniformity: Jiyya na Plasma (musamman a cikin ƙananan ɗakuna masu ƙarancin matsa lamba) yana ba da jiyya iri ɗaya a kan gaba ɗaya. Maganin Corona ya dace da fina-finai masu lebur kawai kuma yana ƙirƙirar yankuna makafi don kayan aikin 3D. Maganin harshen wuta cikin sauƙi yana haifar da zafi na gida ko rashin isasshen magani akan sassa masu siffa.
Tsawon tsufa: Abubuwan da aka gyara Plasma suna tsayawa tsayin daka na makonni da yawa zuwa watanni, kuma gyaran gyare-gyare yana ƙara tsawaita lokacin inganci. Tasirin maganin harshen wuta yana lalacewa cikin sa'o'i da yawa zuwa kwanaki. Maganin Corona ya yi hasarar tasiri a cikin ɗimbin mintuna zuwa sa'o'i da yawa saboda saurin sake fasalin sarƙoƙi na kwayoyin halitta.
IV. Cikakken Kima da Shawarwari Magani
Matsayin Tasiri: Jiyya na Plasma> Maganin harshen wuta> Maganin Corona. Maganin Corona ba shi da tasiri ga PTFE. Maganin harshen wuta ya ɗan fi maganin corona, yayin da akwai tazarar aikin tsararraki idan aka kwatanta da maganin plasma.
Zaɓin Tsari: Don abin dogaro da buƙatun mannewa, ƙarancin matsi na jini ko etching sinadarai na sodium-naphthalene shine zaɓi na farko. Ana iya yin la'akari da matsa lamba na iska don sarrafa fim ɗin layi. Maganin harshen wuta yana iyakance kawai ga matsananciyar bincike na gwaji lokacin da babu kayan aikin plasma kuma ana buƙatar haɗin kai na PTFE, tare da tsananin kulawa akan zafin jiki da samun iska. Ba a ba da shawarar maganin Corona don kunna PTFE ba.
Layin Tsaro na Ƙasa: Duk wani tsari mai zafi da aka yi amfani da shi ga PTFE dole ne a sanye shi da na'urorin gano iskar gas don hydrogen fluoride da sauran iskar gas mai guba da kuma tilasta tsarin samun iska don hana tara kayan bazuwar mai guba da kuma ba da garantin amincin aiki.
Idan kuna son koyan cikakkun bayanai dalla-dalla, yanayin aikace-aikacen da keɓance mafita don samfuranmu masu cikakken kewayon ciki har da yadudduka masu zafin jiki na PTFE, PTFE high-zazzabi m kaset, PTFE high-zazzabi raga belts, m fusing inji bel, guda-gefe PTFE masana'anta, high-resistant fiber bel da high-resistant fiberglass masana'anta, high-resistant fiberglass. masana'anta, da fatan za a tuntuɓe mu ta hanyoyin da ke ƙasa:
