Momwe Kuyeretsedwa Kwa Zinthu Zazikulu Kumakhudzira PTFE Kutentha Kwambiri Kwa Nsalu Zochita

Nsalu ya PTFE yotentha kwambiri (PTFE-yokutidwa ndi fiberglass) ndi yabwino ngati zida zomwe zimagwiritsidwa ntchito popanga. Zigawo ziwiri ndizofunikira: PTFE resin/emulsion (chophimba) ndi fiberglass substrate (kulimbitsa). Zonyansa zilizonse - ma ion zitsulo, ma polima otsika kwambiri, zotsalira, kapena ma alkali oxides - zitha kuyambitsa kulephera msanga: chikasu, kusweka, kutayika kosagwira ndodo, delamination, kapena kutsekeka kwa insulation.

Aokai PTFE imagwiritsa ntchito zida zoyeretsedwa kwambiri komanso kuwongolera mwamphamvu. Bukuli likufotokoza momwe chiyero chimakhudzira gawo lililonse la magwiridwe antchito komanso chifukwa chake kuli kofunikira pakufunsira.

PTFE Raw Material Purity - Ndi Zonyansa Ziti Zomwe Zilipo?

Zodetsedwa wamba mu PTFE ndi:

• Ma monomers osakhudzidwa ndi ma polima otsika kwambiri a molekyulu

• Oyambitsa otsalira ndi ofalitsa (mwachitsanzo, PFOA)

• Metal ions (chitsulo, mkuwa, sodium)

• Zothandizira pakukonza ndi zopangira

Kuyera kwapamwamba kumathandizira kuti zinthuzo zizipereka magwiridwe antchito pafupi ndi zomwe zimafunikira.

1. Kutentha kwa kutentha ndi kukhazikika kwa kutentha

Ma ayoni achitsulo (chitsulo, mkuwa, sodium) amakhala ngati zolimbikitsa zamphamvu za PTFE kuwonongeka kwamafuta . Pansi pa ntchito yayitali yopitilira 260 ° C, ngakhale kutsata zonyansa zachitsulo kumathandizira kusweka kwa ma cell, zomwe zimapangitsa kuti ziwonongeke msanga komanso kusweka. High-chiyero PTFE imakhala ndi kutentha kwapamwamba kwambiri kwa kutentha, kumakhalabe koyera, ndipo kumatsutsa chikasu bwino.

2. Zopanda ndodo ndi khalidwe pamwamba

Ma polima okhala ndi mamolekyulu otsika komanso zinthu zopangira mafuta zimasamukira pamalo opaka pa kutentha kwambiri, kupanga mafunde.

• Katundu wopanda ndodo wawonongeka: Pamwamba pake pamakhala matope ndipo amakonda kumamatira ku zinthu zokonzedwa (chakudya, matepi omatira).

• Chiwopsezo choyipitsidwa: Pazakudya komanso zachipatala, madzi osunthika amatha kuyipitsa zinthu ndikulephera kutsatira ukhondo. Kuyera ndi chizindikiro chachikulu cha nsalu za PTFE zolumikizana ndi chakudya.

3. Kuchita kwamagetsi kwamagetsi

Ma ion osayera (zitsulo zachitsulo, ma halogen ions) amagwira ntchito ngati zonyamulira, amachepetsa kwambiri kukana kwa voliyumu komanso mphamvu yamagetsi. Pazogwiritsa ntchito zopondera kwambiri (mwachitsanzo, ma gaskets otsekereza magetsi), kuyera kwazinthu zopangira ndikofunikira. Pores oyambitsidwa ndi zonyansa amathanso kutulutsa pang'ono.

4. Chemical kukana ndi compactness

Zonyansa zosungunuka zimatuluka zikawonetsedwa ndi media media, ndikusiya ma micro pores mkati mwa zokutira. Zowonongekazi zimalola mpweya wowononga ndi madzi kulowa ndikuwononga gawo lapansi la fiberglass, zomwe zimalepheretsa ntchito yotchinga ya nsalu.

Fiberglass Substrate Purity - Alkali Content Matters

Fiberglass si koyera silicon dioxide. Kapangidwe kake ka mankhwala kumatanthawuza kukana kutentha, mphamvu zamakina, ndi kugwirizana ndi PTFE.

1. Alkali metal oxide content - chinthu chotsimikizika

Pa kutentha kwambiri, ayoni zitsulo zamchere kuchokera kugalasi lopanda chiyero osati kufooketsa nsalu yokha komanso kumayambitsa kuwonongeka kwa PTFE zokutira , kufulumizitsa kulephera kwathunthu. Kuonjezera apo, galasi lapakati / lapamwamba la alkali limatenga chinyezi, zomwe zimapangitsa kuti kukana kwa insulation kugwere kwambiri.

2. Ma saizi agents - zonyansa zina

Sizing agents (wowuma, PVA, mafuta) amagwiritsidwa ntchito powomba magalasi kuti ateteze ulusi. Ngati sichinachotsedwe kwathunthu pamaso pa PTFE zokutira, zotsalira organic carbonize, kuwola, ndi gasify pa sintering pafupifupi 400°C.

• Kuwonongeka kwapamtunda: Maonekedwe achikasu, mawanga akuda, matuza - zinthu zimalephera kuyang'ana mawonekedwe.

• Kumangirirana kofooka kwa nkhope: Zotsalira za kaboni zimatsekereza kugwirizana pakati pa PTFE ndi magalasi a fiberglass, zomwe zimapangitsa kuti pakhale matuza, matuza, ndi kusenda panthawi yantchito.

3. Flexural kutopa kukana

Tinthuvu tating'ono ta mpweya ndi zonyansa za crystalline mkati mwa fiberglass filaments zimachepetsa kulimba kwa ulusi womwewo. Pakupindika mobwerezabwereza, zofooka izi zimakhala malo opsinjika maganizo, zomwe zimayambitsa kusweka koyambirira kwa ulusi ndikuchepetsa kwambiri kusinthasintha ndi moyo wosinthika.

Chidule - Chiyero chimakhazikitsa denga la magwiridwe antchito

Zoyera zakuthupi zimayika magwiridwe antchito a nsalu za PTFE zotentha kwambiri:

• High-purity PTFE imatsimikizira: kutentha kwakukulu kwa utumiki (260 ° C+), kukhazikika kosasunthika kwa nthawi yaitali, kutsekemera kwamagetsi odalirika, ndi kutsata chakudya.

• Magalasi apamwamba a alkali-free fiberglass (E-galasi, Na₂O <0.8%) kuphatikiza zitsimikizo zochotseratu kukula kwake: mphamvu ya gawo lapansi pa kutentha kwakukulu, kukhazikika kwa mawonekedwe, ndikumatira kokhazikika popanda delamination.

Kusayera kosakwanira mu ulalo uliwonse kungayambitse kulephera msanga - chikasu, delamination, kuwonongeka kwa insulation, ndi kutayika kosagwira ndodo - makamaka pansi pazifukwa zovuta: kutentha kwa nthawi yaitali, kutentha kwakukulu, kapena zofunikira zaukhondo.

Aokai PTFE magwero okha mkulu-kuyera PTFE emulsion (otsika zitsulo ion, otsika oligomer) ndi E-magalasi fiberglass nsalu (zopanda alkali, kutentha kwathunthu kutsukidwa). Timapereka certification zakuthupi ndipo titha kuthandizira ntchito zamagulu azakudya komanso zotsekemera kwambiri. Lumikizanani nafe kuti mumve zambiri.

Zomwe zili pamwambazi 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 zotentha kwambiri za PTFE, matepi apamwamba a PTFE, malamba a mesh a PTFE, malamba omangira makina opanda msoko, nsalu imodzi ya PTFE, nsalu zotchinga kutentha kwambiri, ndi malamba osagwira magalasi apamwamba, chonde malamba osamva kutentha kwambiri

• Bambo Liu: + 86 13705266308

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