Momwe mungathetsere ukalamba wa ma washers a rabara?

Makina ochapira mphira nthawi zambiri amakhala ndi moyo wina akagwiritsidwa ntchito, ndipo zida zosiyanasiyana zimakhala ndi moyo wosiyana, zomwe zimadziwika kuti kukalamba. Kotero, ndi zizindikiro ziti zazikulu za ukalamba wa washer wa rabara? Kodi kukonza ukalamba wa washers mphira? Kodi mphira ziyenera kutetezedwa bwanji?

1. Khalidwe laukalamba la ochapira mphira

Pali mawonetseredwe osiyanasiyana a ukalamba wa washer wa rabara, monga kukakamira, kung'ambika, kuumitsa, kusinthika, kuphulika, ndi kusweka pambuyo padzuwa ndi mvula. Zogulitsa zakunja zimatha kukhala zolimba komanso zosweka chifukwa cha mlengalenga. Kuphatikiza apo, ena amathanso kusweka chifukwa cha hydrolysis kapena kuonongeka ndi nkhungu Zochitika izi nthawi zambiri zimakhala zokalamba.

2. Momwe Mungagwiritsire Ntchito Kukalamba Kwa Mpira ndi Kumamatira

(1) Ikhoza kupukuta pamwamba ndi diluent, yomwe imatchedwa kuti diluent kapena mafuta osungunulira. Nthawi zambiri ndimadzimadzi osawoneka bwino, omwe amadziwika kuti Lacquer thinner. Koma ndikofunikira kukumbukira kuti musagwire chowonda chifukwa chikhoza kuwononga khungu.

(2) Ukhoza kufufutidwa ndi Mzimu Wochita thobvu. Polysiloxane polyalkoxy copolymer, yomwe imadziwikanso kuti Foaming Spirit ndi silikoni yosungunuka m'madzi, imapangidwa ndi hydrolyzed ndi Chlorosilane kuti ipange polysiloxane, kenako imasinthidwa ndi polima. Madzi achikasu kapena ofiirira amafuta owoneka bwino

3. Chitetezo ku ukalamba wa ma washers a rabara
Kukalamba kwa mphira ndi chinthu chosasinthika chachilengedwe. Mofanana ndi machitidwe ena a mankhwala, amatsagana ndi kusintha kwa maonekedwe, kamangidwe, ndi kachitidwe. Titha kungochedwetsa kukalamba kwake powerenga malamulo okalamba ndikuwagwiritsa ntchito, koma sitingathe kupeweratu. Njira zodzitetezera zodziwika bwino zimaphatikizapo: njira yotetezera thupi: njira zomwe zimayesa kupeŵa kugwirizana pakati pa mphira ndi zinthu zokalamba, monga kuwonjezera parafini ku rabala, kusakaniza mphira ndi pulasitiki, electroplating, zokutira, etc. Njira yotetezera mankhwala: kuchedwetsa kukalamba kwa labala gaskets kudzera pamachitidwe amankhwala, monga kuwonjezera ma antioxidants.
