Fa'afefea ona filifili mea mo fa'amaufa'ailoga masini

O le filifilia o mea mo lau faʻamaufaʻailoga e taua tele aua o le a faia se sao i le fuafuaina o le lelei, ola ma le faʻatinoga o se talosaga, ma faʻaitiitia faʻafitauli i le lumanaʻi.

Filifiliga o mea e masani ona faʻaaogaina mo faʻamaufaʻailoga masini.

1. Vai mama, vevela masani. Mamaga fe'avea'i: 9Cr18, 1Cr13, fa'afefeteina cobalt chromium tungsten, u'amea lafo; mama mama: resin impregnated graphite, apamemea, palasitika phenolic.

2. Vaitafe vai (o lo'o i ai le palapala), vevela masani. mama mama: tungsten carbide;

mama tutu: tungsten carbide.

3. Suasami, vevela masani mama Moving: tungsten carbide, 1Cr13 fa'afefete cobalt chromium tungsten, u'amea lafo; Fa'amama mama: resin-impregnated graphite, tungsten carbide, cermet.

4. Suavai vevela 100 tikeri. mama fe'avea'i: tungsten carbide, 1Cr13, cobalt chromium tungsten surface, u'amea lafo; Fa'amama mama: resin-impregnated graphite, tungsten carbide, cermet.

5. Gasoline, lubricating suauu, hydrocarbons vai, vevela masani. mama fe'avea'i: tungsten carbide, 1Cr13, cobalt chromium tungsten surface, u'amea lafo; mama fa'amau: fa'a'a'e i resini po'o apa-antimony alloy graphite, palasitika phenolic.

6. Gasoline, lubricating suauu, sua vai hydrocarbon, 100 tikeri mama mama: tungsten carbide, 1Cr13 luga cobalt chromium tungsten; mama static: apamemea fa'a'a'a'i po'o resin graphite.

7. Gasoline, lubricating suauʻu, vai hydrocarbons, o loʻo i ai vaega. mama mama: tungsten carbide; mama tutu: tungsten carbide.

Ituaiga ma le fa'aogaina o mea e fa'amaufa'ailogaina ai mea fa'amaufa'ailoga e tatau ona fetaui ma mana'oga o galuega fa'amau. Ona o faʻasalalauga eseese e faʻamaufaʻailogaina ma tulaga faigaluega eseese o meafaigaluega, o mea faʻamaufaʻailoga e manaʻomia ina ia i ai ni fetuunaiga eseese. O mea e manaʻomia mo mea faʻamaufaʻailoga e masani lava:

1. O mea e maua ai le density lelei ma e le faigofie ona leak ala o faasalalauga.

2. Ia iai le malosi fa'ainisinia talafeagai ma le ma'a'a.

3. Lelei compressibility ma maufetuunaʻi, deformation tumau laiti.

4. E le faamalulu pe pala i le maualuga o le vevela, e le malo pe ta'e i le maualalo o le vevela.

5. E lelei le corrosion teteʻe ma e mafai ona galue mo se taimi umi i acid, alkali, suauu ma isi ala o faasalalauga. O lona voluma ma le maaa suiga e laiti, ma e le pipii i luga o le uamea.

6. Fa'ase'e fa'ase'e la'ititi ma lelei fa'alavalava tete'e.

7. E i ai le fetuutuunai e tuʻufaʻatasia ma le faʻamaufaʻailoga.

8. Lelei matua tetee ma tumau.

9. E faigofie ona faʻaogaina ma gaosia, taugofie ma faigofie ona maua mea.

O le paʻu o le mea faʻamaufaʻailoga e masani ona faʻaaogaina. I le faaopoopo atu i le paʻu, o isi mea faʻamaufaʻailoga talafeagai e aofia ai graphite, polytetrafluoroethylene ma faʻamaufaʻailoga eseese.
