Sezvinhu zvakakosha mumakina ekubatanidza, fastener kuita kwakanyatso kusungirirwa kune inoshanda nharaunda. Mafasteners emhando dzakasiyana-siyana, marapirwo epamusoro, uye zvimiro zvinoratidzira mutsauko wakakura mukuita pasi pemamiriro akasiyana ekushanda, uye sarudzo chaiyo inobata zvakananga kuchengetedzeka uye sevhisi hupenyu hwemidziyo.
General Environmental Adaptability yeMetal Fasteners
Steel fasteners (senge kabhoni simbi uye alloy simbi) anoshandiswa zvakanyanya munzvimbo dzakaoma pane tembiricha yekamuri nekuda kwesimba radzo uye mutengo wakaderera. Iwo anowanzo kuwanikwa mukuvaka, kugadzira michina, uye mamwe minda. Nekudaro, munzvimbo dzine mwando kana marara, kabhoni simbi yakajairwa inoita ngura uye inoda galvanizing, nickel plating, kana Dacromet kurapwa kuti iwedzere kusimba. Stainless steel fasteners (senge 304 ne316), nekuda kwechromium-nickel alloy magadzirirwo azvo, anoita zvinoshamisira munzvimbo yakakwirira-yemunyu kana acidic nealkaline, sezviya zvinowanikwa munzvimbo dzemakemikari nemugungwa. Kuwedzerwa kwe molybdenum kusvika 316 kunopa kupikisa kukuru kune chloride corrosion.
Zvinodiwa Zvakanyanya Zvenzvimbo Yakanyanya
Kukwirisa-mamiriro ekushanda (akadai seinjini nemidziyo yesimbi) inoda kupisa{1}}simbi isingachinjiki kana nickel-zvinamisoro zvakavakirwa pane alloy, izvo zvisingaite oxidation zvinokwanisa kushingirira tembiricha inodarika 600 degrees . Kudzikira-nzvimbo dzetembiricha (zvakadai semidziyo yepolar uye gasi rakanyungudutswa rinochengeterwa) zvinoda zvinhu kuti zvichengetedze kusimba. Austenitic Stainless steel kana copper alloy fasteners anodiwa nekuda kwekudzikira kwadzo-temperature brittleness. Muchikamu chemuchadenga, kuneta kwekudengenyeka kunodawo kutariswa. Titanium alloy fasteners anoshandiswa zvakanyanya nekuda kwekureruka kwavo uye nekuneta kwesimba.
Zvinoenderana Nezve-metallic Fasteners
Zvibatiso zvepurasitiki (zvakadai senaironi ne polyoxymethylene) zvinodzivirira uye zvinodzivirira kugwinya-zvinoita kuti zvikodzere kushandiswa kwakadai semidziyo yemagetsi uye kugadzira chikafu uko kunonetsa kusvibiswa kwesimbi. Zvakadaro, mutoro wavo-unokwanisa kutakura ushoma uye unofanirwa kunyatsoenderana nezvinodiwa nemutoro.
Muchidimbu, kufanirwa kwezvakatipoteredza kwemafasteners kunoda kutarisisa kwakadzama kwezvinhu zvivakwa, kuchengetedzwa kwepamusoro, uye zvinodiwa zvemuchina. Sarudzo chaiyo yakakosha pakuita kuti system ivimbike.
