Zotsatira za Sandblasting/Matt Finishing Treatment on the Surface Structure of PTFE High-Temperature Nsalu

Jiangsu Aokai New Materials, katswiri wopanga nsalu za PTFE zotentha kwambiri, amapereka kusanthula mozama. Chithandizo cha sanding cha Matt chimabweretsa kusintha kwakukulu pamapangidwe apamwamba a nsalu ya PTFE yotentha kwambiri. Imasintha malo oyambira kwambiri, osalala kwambiri kukhala omangika, onyowa mosavuta kuchokera pamiyeso itatu: kapangidwe ka thupi, kukhazikika kwa zokutira ndi mawonekedwe amankhwala apamtunda.

1. Microscopic Morphology: Kuchokera Pagalasi Losalala Kwambiri Kufika Pakupangidwa Kwamafupa Ovuta

The osasamalidwa pamwamba PTFE mkulu-kutentha nsalu ndi yosalala pansi maikulosikopu, opangidwa ndi mosalekeza filimu kusungunula-sintered polytetrafluoroethylene. Chithandizo cha mchenga chimasintha kwambiri micromorphology yake:

• Kuwonjeza kowopsa kwa pamwamba: Kumanga mchenga pamakina (malamba abrasive, maburashi a waya) kapena kuphulika kwa mchenga (corundum, aluminiyamu yoyera yosakanikirana) kumadula ndi kukhudza pamwamba, kusema mazenje, maenje ndi nsonga zosawerengeka. Zizindikiro za roughness Ra (masamu amatanthawuza kupatuka kwa mbiri yoyesedwa) ndi Rz (kutalika kwa mfundo khumi za zolakwika) zimachulukitsa kwambiri.

· Mapangidwe a makina omangira nangula: Ma micro-grooves awa sizinthu zosavuta, koma zolumikizana za 3D. Ichi ndiye pakatikati pa zomangira: zomatira zimalowa m'mipata iyi ndikuchiritsa kuti apange kulumikizana kwakuthupi kumangirira kapena zokutira.

· Kufanana kwapamwamba: Kuyika mchenga koyenera kumapereka kutha kwa matte. Kuwongolera kolakwika kwa njira kumayambitsa madera okhala ndi mchenga wambiri (zopaka zopyapyala kwambiri) ndi zigamba zosalala zosasunthika, zomwe zimapangitsa kuti pakhale mawonekedwe osasinthika.

2. Kuphimba Kukhulupirika: Kuyambira Kanema Wosasinthika mpaka Wowonongeka, Malo Owonekera

Ichi ndiye chiwopsezo chovuta kwambiri chomwe chimafuna kuwongolera mosamalitsa ndondomeko, kudziwitsa mwachindunji ntchito yayikulu ya chinthucho:

· Kupatulira kwa PTFE wosanjikiza: Kutsuka mchenga ndi njira yochotsa zinthu zakuthupi. Kupaka kwa PTFE kwa nsalu zotentha kwambiri nthawi zambiri kumakhala kuyambira makumi mpaka mazana a ma microns wokhuthala. Mchenga wochulukirachulukira umachepetsa makulidwe a zokutira, kutsitsa mphamvu ya dielectric ndi moyo wautumiki wa mankhwala oletsa dzimbiri.

Kuopsa kwa gawo lapansi la fiberglass (chilema choopsa kwambiri): Kuzama kwa kugaya kukadutsa makulidwe a zokutira za PTFE, nsalu ya pansi pagalasiyo imachotsedwa, zomwe zingayambitse zovuta zingapo:

1. Kutayika kwa zinthu zopanda ndodo: Zingwe zamagalasi zowonekera zimamatira kuzinthu;

2. Kulowa kwa chinyezi ndi mankhwala: Nthunzi yamadzi ndi mankhwala zimalowa mu nsalu kudzera mu capillary action of glass fibers, zomwe zimapangitsa kuti delamination ndi kuwonongeka mofulumira;

3. Kuchepetsa mphamvu zamakina: Kuphwanyidwa kwa ulusi wagalasi kumapangitsa kutsika kwakukulu kwamphamvu yamphamvu ya nsalu yonse.

Kubadwa kwa ma microcracks ndi zinyalala zowunjikana: Kudula kwa abrasive pa PTFE kumaphatikiza kung'ambika komanso kung'ambika kwa ductile, kupanga ma microcracks ndi ma burrs m'mphepete mwa groove ndi pansi. Pakadali pano, tchipisi ta PTFE zovumbulutsidwa zitha kuyikanso mosasamala, ndikupanga zomangira zokhala ngati chilumba zomwe zimasokoneza kudalirika kwa zokutira kapena kumangirira kotsatira.

3. Surface Chemical State: Kuchokera ku Ultra-Inert kupita ku Activated

Ngakhale kuti mchenga ndi mankhwala ochiritsira, umapangitsanso kusintha kwa zinthu zakuthupi:

· Mphamvu zokwera pamwamba: PTFE yoyera imakhala ndi mphamvu zotsika kwambiri (18–20 mN/m), yokhala ndi ngodya yolumikizana ndi madzi yopitilira 108°. Pambuyo pa mchenga, malo omwe angopangidwa kumene komanso maunyolo osweka amawonetsa malo omwe ali ndi mphamvu zambiri, kukweza mphamvu pamwamba pa 40 mN/m. Madontho amadzi amafalikira ndikunyowetsa pamwamba, kuwonetsa hydrophilicity kwakanthawi, komwe kumazirala pang'onopang'ono pakapita nthawi.

Kuyambitsa kwakanthawi kwamagulu ogwira ntchito ku polar: Kugaya kwamphamvu kwambiri kumapangitsa kuti pakhale kusinthana pakati pa unyolo wa molekyulu ya PTFE yosweka ndi mpweya / chinyezi mumlengalenga, kutulutsa nthawi yomweyo magulu ogwirira ntchito monga carbonyl (C=O) ndi hydroxyl (-OH). Maguluwa amathandizira kulumikizana kwamankhwala kuti apititsenso kusintha kwamankhwala kapena zomatira.

Chidule cha Zotsatira Zonse

Mwachidule, chithandizo chamchenga choyenerera chimapanga mawonekedwe a yunifolomu, ovuta, oyendetsedwa ndi micro-nano pa PTFE nsalu popanda kuwononga gawo lapansi la fiberglass.

· Kusintha kwabwino: Kumapanga mawonekedwe olumikizana ndi makina kuti athetse vuto la PTFE losamamatira.

· Zoyipa zoyipa: Imadzipereka kuti isagwire ntchito yokhazikika, yosalala komanso yowoneka bwino, yokhala ndi ziwopsezo zokhazikika zakuwonongeka kwa gawo lapansi komanso moyo wamfupi wautumiki.

Choncho, pachimake cha ndondomeko yagona mu ulamuliro yeniyeni ya zinthu kuchotsa kuya - kokha pamwamba PTFE pamwamba wosanjikiza ndi abraded, popanda kukhudza fiberglass kulimbitsa mafupa. Nsalu yomwe imagwiritsidwa ntchito nthawi zambiri imatumizidwa ku zokutira kapena kumangiriza nthawi yomweyo kuti igwiritse ntchito bwino kwambiri momwe imapangidwira pamwamba.

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

Ngati mukufuna kudziwa mwatsatanetsatane, zochitika ntchito ndi mayankho makonda athu zonse katundu katundu kuphatikizapo PTFE mkulu kutentha nsalu, PTFE mkulu-kutentha zomatira tepi, PTFE mkulu-kutentha mauna lamba, msokonezo kutentha atolankhani lamba, single-mbali PTFE nsalu, mkulu kutentha zosagwira magalasi, kukhudzana ndi magalasi zosagwira magalasi, chonde kukhudzana ndi magalasi zosagwira magalasi conveyor.

Nthawi zonse timatsatira filosofi yautumiki waukatswiri ndi kukhulupirika, kupereka ndi mtima wonse mayankho amakampani omwe amasiyanitsidwa ndi ntchito zamakasitomala oganiza bwino kwa onse othandizana nawo!
