Indlela Yokubala Upende Wokumaka Umgwaqo kanye Nokusetshenziswa Kwe-Glass Bead
Ukubalwa kokusetshenziswa kopende lokumaka umgwaqo okuthembekile kuqala ngendawo ezokwamukela izinto zokwakha. Ubude bomgwaqo bubodwa abwanele: ikhilomitha elilodwa lomugqa oqinile ongu-100 mm, ikhilomitha elilodwa lomugqa ophukile ongu-150 mm kanye nokuwela i-zebra konke kukhiqiza izindawo ezipendiwe ezahlukene.
Bala indawo yokumaka kuqala, uyiguqule ibe upende noma inani le-thermoplastic, bese ubala ubuhlalu bengilazi obuwela phansi. Engeza imali yokuthenga kuphela ngemva kokuhlola ithenda, isiqondiso somhlinzeki noma amarekhodi esayithi aqinisekisiwe. I-calculator ayikwazi ukusindisa iphethini yomugqa engalungile; izomane ikhiqize impendulo engalungile ngokuzethemba okumangalisayo.
Isibali Sokupenda Upende Wokumaka Emigwaqweni: Amafomula Amane Ayisisekelo
Indawo ephawuliwe = ubude bomugqa × ububanzi bomugqa × isici sokumaka
Ubuningi be-thermoplastic = indawo ephawuliwe × izinga lezinto ezicacisiwe
Ubuningi be-Glass bead = indawo ephawuliwe × izinga le-bead elicacisiwe
Inani lokuthenga = inani elibaliwe × isici sesibonelelo sephrojekthi
Sebenzisa amamitha ubude nobubanzi, ukuze u-100 mm ube ngu-0.10 m. Ukuze uthole i-thermoplastic, sebenzisa izinga le-kg/m² elishicilelwe noma ubale isisindo kusukela ekujikeni nasekuxineni. Ukuze uthole upende olubandayo oluwuketshezi, sebenzisa ukujiya kwefilimu emanzi noma idatha yokumbozwa komkhiqizi.
