Momwe Njira Zochizira Pamwamba Zimasinthira Mapangidwe a Pamwamba pa PTFE Nsalu Yotentha Kwambiri

Nsalu yotentha kwambiri ya PTFE ndi yamtengo wapatali chifukwa chosagwira ndodo, yosagwira kutentha, komanso anti-corrosion. Koma ultra-smooth, low-surface-energy, yopanda mphamvu ya mankhwala yomwe imapangitsa kuti ikhale yabwino kumasula mapulogalamu imapangitsanso kukhala kosatheka kugwirizanitsa, kusindikiza, kapena laminate.

Yankho lake ndi pamwamba mankhwala - uinjiniya onse microstructure ndi mankhwala zikuchokera PTFE pamwamba kutembenuza kuchokera sanali bondable kuti bondable.

Aokai PTFE imapereka nsalu za PTFE zokhala ndi njira zosiyanasiyana zochizira pamwamba. Bukuli likufotokoza njira zinayi zodziwika bwino - etching mankhwala, chithandizo cha plasma, chithandizo cha corona, ndi chithandizo cha laser - komanso momwe chilichonse chimasinthira padziko lapansi mwakuthupi komanso mwamankhwala.

Chemical Etching (Machiritso a sodium-Naphthalene Solution)

Njira yochizira yonyowa iyi imapereka zotsatira zokhalitsa komanso zimawona kugwiritsa ntchito kwambiri kwa PTFE.

1. Kusintha kwa thupi

Sodium-naphthalene complex solution imatulutsa PTFE pamwamba pochotsa maatomu a fluorine kuchokera pamwamba. Poyambirira kalilole-wosalala pamwamba pake amakhala ndi ma micron- to nanoscale zisa za uchi- kapena maenje ooneka ngati korali ndi maenje. Kukhwinyata uku kumakulitsa kwambiri malo enieni ndikupanga nsonga zomata zomata.

2. Kusintha kapangidwe ka mankhwala

Uku ndiye kusintha kofunikira. Sodium yochepetsetsa kwambiri imatulutsa maatomu a fluorine kuchokera ku PTFE carbon backbone, kusiya unyolo wa carbon unsaturated ndi ma radicals aulere. Malo ogwira ntchitowa amakhudzidwanso ndi chinyezi ndi mpweya mu mpweya wozungulira kapena njira, ndikuyambitsa magulu ogwira ntchito polar kuphatikizapo carbonyl (C=O), hydroxyl (-OH), ndi carboxyl (-COOH) . Pakalipano, mpweya wa carbon ukukwera ndipo wosanjikiza umasanduka woderapo-bulauni kapena wabulauni-wakuda.

3. Zotsatira

A quasi-carbonized yogwira wosanjikiza amapangidwa. Mphamvu zapamtunda zimakwera kuchokera pansi pa 20 dyn/cm kwa PTFE yoyera yosakanizidwa kufika pamwamba pa 40-50 dyn/cm , zomwe zimapangitsa kulumikizana mwachindunji ndi zomatira zochokera m'madzi. Kusintha kwapangidwe kumeneku ndi kosatha . Komabe, wosanjikiza mankhwala ndi angapo microns woonda ndipo amafuna chitetezo mosamala.

Chithandizo cha Plasma

Nthawi zambiri amagwiritsidwa ntchito pokonza pang'ono kapena pamzere, chithandizo cha plasma chimagawidwa kukhala vacuum plasma ndi plasma-pressure plasma.

1. Kusintha kwa thupi

Tinthu tating'onoting'ono tamphamvu (ma elekitironi, ma ion, ma radicals aulere) mosalekeza amawombera pamwamba pa PTFE ndikuyambitsa zotsatira za sputter-etching. Chojambula chowoneka bwino kwambiri cha nanoscale chimapangidwa pamwamba; malire ofooka amachotsedwa popanda kuwononga gawo lapansi la fiberglass. Pang'ono ndi pang'ono, pamwamba pa crystalline chochuluka chopangidwa ndi amorphous micro-roughened state.

2. Kusintha kapangidwe ka mankhwala

Njira ya gasi imasankha magulu omaliza ogwira ntchito:

• Kuchiza kwa gasi wa inert (mwachitsanzo, argon): Kuphwanya zomangira za CF kuti apange ma radicals aulere pamtundu wotsatira wamagulu a polar

• Mipweya yogwira ntchito (oxygen, ammonia): Molunjika kumezanitsa hydroxyl, carbonyl, ndi magulu amino pa unyolo wa maselo

3. Zotsatira

Malo oyera, onyowa kwambiri a nano-roughened amapezeka. Mphamvu yolimbikitsira imawonongeka pakapita nthawi , chifukwa chake, kuthirira kuyenera kuchitika mutangolandira chithandizo cha plasma. Ubwino wake waukulu ndi wosanjikiza wosaya kwambiri, womwe sumasintha makulidwe azinthu zonse ndi mtundu woyambirira.

Chithandizo cha Corona

Njira yotulutsira mphamvu yamagetsi yomwe imagwira ntchito mwachangu pazinthu zowonda-filimu koma imakhala ndi vuto lofulumira.

1. Kusintha kwa thupi

Kutulutsa kwamphamvu kwamphamvu kwa corona kumatulutsa kuwala kwa micro-arc. Mphamvu zochokera ku ma elekitironi amphamvu kwambiri zimathyola unyolo wa ma molekyulu a PTFE, kupanga malo okhazikika, ndikuyika mawonekedwe osaya, osawoneka bwino. Chifukwa cha kuchepa kwa mphamvu komanso kutalika kwa nthawi yayitali poyerekeza ndi chithandizo cha plasma, corona imangopanga kukwiyitsa kwa dzenje kocheperako.

2. Kusintha kapangidwe ka mankhwala

Mitundu ya ozoni ndi okosijeni yokhazikika imapangidwa m'malo otulutsa. Oxidation imayambitsa magulu a hydroxyl, peroxides, ndi magulu a carbonyl kuti akweze mphamvu zapamwamba kwambiri.

3. Zotsatira

Mankhwalawa amangokhudza gawo lochepa kwambiri lapamwamba lokhala ndi kusintha kosasunthika, komwe kumamatira-kuwonjezera mphamvu kumazimiririka mofulumira. Imagwiritsidwa ntchito ngati njira yolimbikitsira kwakanthawi mumzere. Pazinthu zokhuthala, zodzazidwa monga nsalu zotentha kwambiri za PTFE, chithandizo cha corona nthawi zambiri chimapereka zotsatira zotsika poyerekeza ndi mankhwala a plasma ndi etching yamankhwala.

Chithandizo cha Laser

Kusintha mwatsatanetsatane pamwamba pogwiritsa ntchito ukadaulo wa excimer-laser kapena femtosecond-laser.

1. Kusintha kwa thupi

Zotsatira za Photothermal ndi photochemical zimapanga ndendende masikelo a micron monga ma ripples, grooves, kapena micro-pillars. Maonekedwe opangidwa mwaluso awa amatha kusinthidwa molondola kuti apange ma geometries abwino kwambiri olumikizirana ndi zomatira.

2. Kusintha kapangidwe ka mankhwala

Ma photon a laser amphamvu kwambiri amathyola zomangira zamphamvu kwambiri za CF, zomwe zimayambitsa kuwonongeka kwamafuta am'deralo ndi carbonization. Madera otetezedwa amakhala ngati ma diamondi ngati ma carbon kapena graphic carbon layers okhala ndi okosijeni wambiri. Ma lasers a Ultraviolet excimer amatha kumezanitsa ma monomers omwe amagwira ntchito kudzera pazithunzithunzi zachindunji popanda carbonization.

3. Zotsatira

Kusintha kosinthika, kolunjika, komanso kofananira kwa thupi ndi polarity yamankhwala kumatheka. Polima inert pamwamba amasandulika kukhala wosanjikiza mpweya-oxygen wolemera ndi roughable roughability ndi mkulu pamwamba mphamvu, kupereka mkulu-mphamvu ndi okhalitsa ntchito yomangira.

Chidule - Kusintha Kwathupi ndi Chemical

Njira zinayi zonse zothandizira zimakwaniritsa zosintha ziwiri:

1. Kusintha kwa thupi

Malo osalala a ma molekyulu amasinthidwa kukhala malo owumbika ophimbidwa ndi ma micro-nano-scale cavities, grooves, ndi ma protrusions amtundu wa korali, kumapereka zida zambiri zolumikizirana zamakina zomata zomata.

2. Kusintha kwa mankhwala

Pansi mphamvu yochepa yomangidwa kuchokera ku maunyolo a perfluorocarbon (-CF₂-CF₂-) imasandulika kukhala malo amphamvu kwambiri omwe ali ndi magulu a polar omwe ali ndi mpweya ndi nayitrogeni. Malo osinthidwa amatha kunyowetsedwa ndi guluu wokhazikika ndikupanga zomangira za haidrojeni kapena zomangira zamakemikolo okhala ndi mamolekyu omatira.

Aokai PTFE imapereka nsalu za PTFE zokhala ndi mankhwala (zokhazikika, zakuda) komanso chithandizo cha plasma (choyera, choteteza mitundu, zenera lotsegula lalifupi) ngati njira zomwe mungasankhe. Chithandizo cha laser chilipo pamapulogalamu apadera omwe amafunikira njira zolondola. Lumikizanani nafe kuti tikambirane zofunikira zanu zomangira.

Zomwe tatchulazi zaukadaulo zimaperekedwa ndi Malingaliro a kampani Jiangsu Aokai New Materials Technology Co., Ltd.

Ngati mukufuna kudziwa zambiri zatsatanetsatane, mawonekedwe ogwiritsira ntchito ndi mayankho makonda pazogulitsa zathu zonse, kuphatikiza nsalu ya PTFE yotentha kwambiri, tepi yomatira ya PTFE, lamba wotentha kwambiri wa PTFE, lamba wosasunthika, lamba wambali imodzi PTFE, nsalu yotchinga kutentha ndi magalasi osasunthika, chonde chosagwira kutentha kwagalasi tiuzeni kudzera muzomwe zili pansipa:

• Bambo Guo: +86 18944819998

• Bambo Liu: + 86 13705266308

Timatsatira mfundo zamabizinesi a ukatswiri ndi kukhulupirika, odzipereka kuti apereke mayankho amtundu umodzi wamakampani komanso chisamaliro chamakasitomala osamala!
