Zisindikizo za PTF

Chisindikizo cha Polytetrafluene (PTF) (omwe amadziwikanso kuti Ptyfe Chisindikizo kapena Chisindikizo cha PTFF

Zabwino za zisindikizo za PTF

1.

Zisindikizo za PTFE zili ndi zotsutsana zabwino zamankhwala ndipo zimatha kupewa kukokoloka ndi zinthu zosiyanasiyana zamankhwala monga asidi, alkali, ndi mchere. Khalidwe ili limapangitsa zilankhulo za PTT zomwe zimagwiritsidwa ntchito kwambiri pamakampani opanga mankhwala, makampani ogulitsa mankhwala ndi makampani azakudya.

2. Kulimba kwapamwamba Kwambiri:

Zisindikizo za PTF ali ndi kukana kwamphamvu kwambiri komanso kumatha kugwira ntchito m'malo otentha kwambiri kwa nthawi yayitali. Malo osungunuka a PTF ndi 327 ° C, Kugwiritsa ntchito mosalekeza Kugwiritsa ntchito -200 ° C mpaka 260 ° C, ndipo Kutentha kwakanthawi kochepa kumatha kufikira 300 ° C, kotero itha kugwira ntchito mokhazikika mu 300 ° Khalidwe ili limapangitsa chisindikizo cha PTF omwe amagwiritsidwa ntchito kwambiri mu ndege, ansespace, mphamvu ya nyukiliya ndi minda ina.

3. Mkangano wotsika:

Zisindikizo za Polytetrafloeneene (zomwe zimadziwikanso ngati zisindikizo za PTFE kapena Zisindikizo za PTFF) zimakhala ndi zogwirizana kwambiri, zomwe zimawapangitsa kukhala oyenda bwino komanso nthawi yayitali popewa zigawo zosuntha. Khalidwe ili limapangitsa chisindikizo cha PTF limagwiritsidwa ntchito kwambiri m'makina, magalimoto, zombo ndi minda ina.

4.

Chisindikizo cha PTF ndichinthu chamagetsi abwino kwambiri omwe amatha kugwira ntchito bwino m'malo magetsi. Khalidwe ili limapangitsa chisindikizo cha picfes chomwe chimagwiritsidwa ntchito kwambiri pamagetsi, zamagetsi ndi minda ina.

5. Valani bwino kukana:

Zisindikizo za PTFE zimavala bwino kukana ndipo zimatha kutumikira kwa nthawi yayitali m'mikhalidwe yovuta kwambiri monga katundu wolemera, kuthamanga kwambiri, komanso kutentha kwambiri. Khalidwe ili limapangitsa chisindikizo cha picre lomwe limagwiritsidwa ntchito kwambiri mafakitale olemera monga makina opasili ndi makina opanga materochemical.

2. Zoyipa za Zisindikizo za PTF

1. Mtengo Wokwera:

Poyerekeza ndi zida zina zosindikizira, mtengo wa zisindikizo wa PTFF ndi wapamwamba, womwe ndi chimodzi mwazinthu zomwe zimapangitsa kutchuka kwake.

2. Kukula Kotsika:

Zisindikizo za PTF ili nazo zimakhala ndi mphamvu zochepa ndipo zimatengeka ndi magulu owoneka bwino, kuti asakhale oyenera mu katundu wapamwamba, kugwiritsa ntchito kwambiri.

3. Kukula kwakukulu:

Zisindikizo za Polytetrafloeneene Kutembenuka kutentha, amakonda kusinthasintha, kumakhudzanso kusindikiza.

Polytetrafluorofentlene (PTF) Mafuta amafuta amalowetsa chidindo cha mphira wa mphira, chomwe chimathetsa vuto la madzi ndi kuthira kwamafuta kwa mafupa osindikizira mafuta.

1. zabwino za PTFF Kusindikiza Mafuta

Polytetrafluoro 11nbyene (PTF), ndi wopopera wa tetrafluofentlene monomer. Ili ndi izi:

.

(2) Kukhazikika kwa matenthedwe: kutentha kwa Pyrolysis kuli pamwamba pa 400 ° C. Chifukwa chake, ptfe imatha kugwira ntchito nthawi zambiri mkati mwa kutentha kwa -200 ° C mpaka 300 ° C.

.

.

2. Chisindikizo chamagetsi cha PTF

Ptfe yoyera siyikuwonongeka. Kuti muchite zothandiza, iyenera kudzazidwa ndi kusinthidwa. Timagwiritsa ntchito njira ziwiri: imodzi ndi yowonjezera kusinthidwa, kuwonjezera fiber galasi, kaboni fiber, graphite, molybdenum yotsuka, ndi zina. Chinacho ndichabwino chodzaza, kuwonjezera polyphenylene ulen, polyphenylene sulpide, etc. to polytetrafluorlene (kutsukidwa kwa madzi, chakudya, ndi mankhwala opangira mankhwala). Mwa kudzaza kusinthidwa, kuvala kukana kwa polytetrafluoroonne kumakulitsidwa ndi nthawi 2000, ndipo kuumbika kwa matenthedwe kumawonjezeka, kulola chisindikizo cha mafuta kuti chikwaniritse zofunika kwambiri.

3. Mfundo za PTF

Mlomo wa mafuta a PTFF amakokedwa mu mawonekedwe a lipenga pamakonzedwe. Popeza Ptfe ali ndi luso lokumbukira pambuyo pokokedwa, kutentha kwanyengo komwe kumapangidwa panthawiyo kudzapangitsa kuti milomo ithe, motero thandizo la kasupe silofunikira. , idzakumbatira state yolimba, siyilepheretsa kukhala ndi kusiyana kulikonse ndi shaft, ndikulipiritsa kuvala.

Kusanthula kwa magawo a Pulytetrafluoroene sels (omwe amadziwikanso kuti zisindikizo za PTFF kapena Zisindikizo za PTFF) -

1. Mankhwala Opanga Mankhwala PTFE Mphete ya mphete:

Zisindikizo za PTFE zili ndi mankhwala abwino kwambiri omwe amatsutsana ndi mankhwala ndipo amatha kugwira ntchito mokhazikika monga ma acidis, alkali, ndi mchere. Chifukwa chake, imagwiritsidwa ntchito kwambiri pamakampani amakampani kuti asindikize ma piyo osiyanasiyana, mapampu, mavuvu ndi zida zina.

2. Rilch Kupirira mphete mu malonda ogulitsa:

Zisindikizo za PTFF zimagwiritsidwa ntchito kwambiri pamakampani opanga mankhwala chifukwa amatha kukana kusinthasintha kwa mankhwala osiyanasiyana ndi masinthidwe apamwamba komanso malo okhala ndi thanzi, ngakhale kukwaniritsa mankhwala azaumoyo komanso osayipitsa mankhwala. M'magulu a mankhwala opangira mankhwala, zida zamankhwala, ndi zina zambiri, zisindikizo za PTFE zimagwiritsidwa ntchito kwambiri.

3. Makampani opanga chakudya cha PTF

Zisindikizo Zisindikizo za PTF zimagwiritsidwanso ntchito kwambiri pazogulitsa zam'madzi chifukwa cha kukana kwawo kwamankhwala ndi ukhondo. Pakudya chakudya, kusungirako, mayendedwe, ndi zina zambiri, zisindikizo za PTFE zitha kupangira chitetezo chodalirika.

4. Mphete za PTF ku Arospace Munda:

Zisindikizo Zisindikizo za PTF zimagwiritsidwanso ntchito kwambiri mu gawo la Aerossace chifukwa cha kutentha kwabwino kwambiri komanso mankhwala kuteteza. Ku Irossece injini, spacecraft, ndege, ndi zina zowonjezera, zisindikizo za PTFE zimatha kusindikizidwa ndi chitetezo chodalirika komanso chitetezo chokwanira.

5. PTF akusungani mphete m'munda wamakina:

Zisindikizo za PTF zimagwiritsidwanso ntchito kwambiri m'munda wamakina chifukwa limakhala ndi chisonyezo chochepa komanso kuvala bwino kukana, komwe kumatha kusintha mwaluso komanso moyo wa zida zamakina. Mu zida zamakina, zida zamagetsi, mapampu, etc., zisindikizo za PTFE zitha kuwonetsetsa kuti zidachitika bwino.
