PTFE Micro Powder Imatulutsa Magesi Apoizoni Pakutentha Kwambiri?
PTFE micro powder ndi mankhwala omwe amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana monga chemistry, mechanics, mankhwala, nsalu, ndi mafakitale a zakudya. Itha kuwonjezeredwa kumafuta opaka mafuta ndi mafuta kuti muchepetse mikangano ndikupititsa patsogolo ntchito zamafuta. Mukawonjezeredwa ku mphira, pulasitiki, ndi zitsulo zosakaniza, PTFE ufa waung'ono ukhoza kuwonjezera kukana kwa dzimbiri kwa zinthuzi chifukwa zinthuzi sizilimbana ndi dzimbiri komanso zimakhala ndi zolakwika zazikulu. Kuwonjezera PTFE ufa wawung'ono ukhoza kuwonjezera moyo wa mankhwalawo.
nditero PTFE ufa umatulutsa mpweya wapoizoni pa kutentha kwakukulu?
PTFE ufa wocheperako ndi chinthu chaufa choyera chokhala ndi kukhazikika kwamankhwala komanso kukana kutentha kwambiri. Komabe, tonse tikudziwa kuti zinthu za mankhwala zimatha kusintha chifukwa cha kusintha kosiyanasiyana. Chifuniro PTFE micro powder amasintha pakatentha kwambiri? Kodi idzatulutsa mpweya wapoizoni pakatentha kwambiri? Tiyeni timvetsetse momwe tingagwiritsire ntchito mankhwalawa moyenera.
Choyambirira, PTFE ufa wocheperako ndi chinthu cha inert chokhala ndi kukhazikika kwamphamvu kwamankhwala. Sichisinthika kapena kuwonongeka mosavuta. Nthawi zambiri amagwiritsidwa ntchito m'malo mwa minyewa yobzalidwa m'makampani azachipatala ndipo amatha kuphatikizana ndi zinthu zosiyanasiyana popanda kukanidwa mosavuta, zomwe zimapangitsa kuti zikhale zosavuta kugwiritsa ntchito pophatikiza. Choncho, pansi pa kutentha kwabwinobwino, PTFE ufa waung'ono sutulutsa zinthu zapoizoni. Komabe, akadali chinthu chamankhwala, ndipo kutentha kwakukulu kungayambitsebe PTFE kusintha pang'ono. PTFE ufa wawung'ono udzafewetsa pang'ono pa 190 digiri Celsius ndikusungunuka kwathunthu pafupifupi madigiri 327 Celsius. Idzawola pang'onopang'ono ndikutulutsa zinthu zapoizoni zopitirira madigiri 400 Celsius.
Kachiwiri, pa kutentha kwambiri kuposa madigiri 400 Celsius, PTFE ufa wawung'ono udzatulutsa octafluoroisobutene woopsa kwambiri. Ngati munthu atakoweredwa mwangozi, amatha kuyambitsa zizindikiro monga chizungulire, nseru, kulimba mtima pachifuwa, ndipo zikavuta kwambiri, zimatha kuyambitsa edema yam'mapapo komanso kuvulaza thanzi.
Mwambiri, PTFE ufa wawung'ono ungagwiritsidwe ntchito nthawi zambiri pansi pa 260 digiri Celsius. Pa 260 digiri Celsius, PTFE ufa wochepa ukhoza kukhalabe wokhazikika. Pamwamba pa madigiri 260 Celsius, zosintha zidzachitika. Pogwiritsidwa ntchito tsiku ndi tsiku, kutentha kwakukulu sikungapangidwe, ngakhale panthawi yophika tsiku ndi tsiku, ndipo kutentha sikudzapitirira madigiri 170 Celsius. Chifukwa chake, zinthu zosiyanasiyana monga pulasitiki, mphira, ndi zitsulo zomwe zili PTFE ufa wocheperako ungagwiritsidwe ntchito nthawi zonse pamoyo watsiku ndi tsiku. Nthawi zambiri, kuvulaza thupi la munthu ku zipangizo munali PTFE ufa wochepa ukhoza kunyalanyazidwa.
Choncho, PTFE ufa yaying'ono sipanga zinthu zapoizoni pansi pa kutentha kwabwinobwino, pokhapokha pa kutentha kwapadera.
