Momwe Mungasankhire Chiwonetsero cha Mavalidwe a Gulugufe

Kusankhidwa kwa zida zosindikizira zaMavalidwe a Gulugufekumafuna kuganizira zinthu zambiri. Pokhapokha posankha zinthu zoyenera gulu Izi ndi mfundo zazikuluzikulu komanso mawonekedwe wamba omwe amakambirana posankha:

Kuganizila

1. Kugwira ntchito zapakatikati: Zipangizo zamankhwala zolimba, monga polytetrafluofenthlene (ptfe), iyenera kusankhidwa m'malo olimba a acidic ndi alkaline; Pankhani yazinthu zakuthupi, ma media otentha kwambiri amatha kuthamangitsa ukalamba ndi kusinthika kwamphamvu, komanso malo opanikizika kwambiri amafunikira mphamvu zambiri komanso mphamvu zochulukitsa. Media yokhala ndi tinthu tating'onoting'ono timafunikira zinthu zosagonjetseka.

2. Kutentha kogwira ntchito ndi kupanikizika: Zipangizo zosiyanasiyana zopindika zimakhala ndi kutentha kwambiri. Zida zolimba za mphira nthawi zambiri zimagwiritsidwa ntchito pakati -30 ℃ ndi 120 ℃, pomwe mapulaneti apadera amatha kupirira kutentha kwambiri. Pansi pamavuto akulu, zida zimafunikira kukhala ndi mphamvu zokwanira komanso zotukuka, monga zida zosindikizira zitsulo m'masipu opanikizika kwambiri, omwe ali oyenera kwambiri.

3. Valavu yotseguka ndi kutseka pafupipafupi: pomweGulugufe wa GulugufeAtseguka ndikutseka pafupipafupi, zinthuzo ziyenera kukhala zotopa komanso kutopa komwe kumayambitsa kutopa. Nitrile rabara (NBR) imakhala ndi vuto kukana ndipo ndi yoyenera nthawi ngati imeneyi.

4. Voomer: Sankhani zida zotsika mtengo kuti muchepetse ndalama pokumana ndi zofunikira. Zipangizo wamba za mphira zimakhala ndi mitengo yotsika, pomwe ma prostics apamwamba kwambiri kapena zinthu zitsulo zosindikizira zitsulo zili ndi mitengo yayikulu.

Zofala Zinthu

1. Mpira: Nitrile Mediene mphira (Nbr) ndi mafuta osagwirizana ndi mafuta, osakanikirana, koma oyenera kusanja kwa mafuta, koma oyenera kuwononga mafuta a -320 ℃ ndi makakamizo; Fluorororubber (fkm) amalimbana ndi kutentha kwambiri, mafuta, ndi kuchuluka kwa mankhwala, koma ndizokwera mtengo ndipo sizikuwoneka bwino. NdioyeneraMavalidwe a GulugufeMu mankhwala azamitundu ndi mankhwala okhala ndi zovuta zapamwamba kuyambira -20 ℃ mpaka 200 ℃; Ethylene Proble Eprable (EPDM) ndi madzi ogwirizana ndi madzi, ozoni akuzunza, kukalamba, ndipo sakaniza Mafuta. Ndioyenera kupangira madzi ndi matenthedwe okhala m'mapazi kuyambira -50 ℃ mpaka 150 ℃.

2. Plastics: Polytetrafluorothynene (PTF) ali ndi bata labwino kwambiri la mankhwala, kutentha kwambiri kukana, komanso zokutira pang'ono, koma zolemetsa zochepa komanso mphamvu zowoneka bwino. Ndioyenera malo okhala ndi mphamvu zovulaza kuchokera -180 ℃ mpaka 250 ℃; Polyamide (pa) ili ndi mphamvu yayikulu, kuuma, kuvula kukana, ndi kupha mafuta bwino, koma ili ndi madzi otsatsira madzi ambiri komanso kukhazikika kosavuta. Ndizoyenera kwa mafuta apakati komanso ochepa okhala ndi malo opezeka pa -40 ℃ mpaka 100 ℃.

3. Zitsulo: Chitsulo chopanda dzimbiri chili ndi mphamvu zambiri, kutunkha kwa madzi, mapiri odalirika, koma mtengo wokulirapo komanso wothira kutentha kwambiri, komanso malo okhala zithunzi zapamwamba; Chovala cha mkuwa chimakhala ndi mawonekedwe abwino, amachititsa, komanso kukana kutukuka, ndipo ndikosavuta. Komabe, ili ndi mphamvu zochepa ndipo amakonda makuti oxidation kutentha kwambiri. Ndizoyenera kuti valavu ya Gulugufe ikhale yokhala ndi kutentha kochepa komanso kufunikira kwake.
