Sei uchifanira kusarudza polyurethane yemakasita emaindasitiri uye ndeapi mabhenefiti ayo?

Polyurethane (PU), zita rakazara re polyurethane, ipolymer compound, yakagadzirwa muna 1937 naOtto Bayer nevamwe. Polyurethane ine mapoka maviri makuru: polyester ne polyether. Inogona kugadzirwa kuita mapurasitiki e polyurethane (kunyanya furo), polyurethane fibers (inozivikanwa se spandex muChina), polyurethane rabha uye elastomers. Polyurethane ipolymer stool yakakodzera kushandiswa sechivharo chevhiri mukugadzira macasters emaindasitiri.

Zvakanakira zvikuru zve polyurethane casters zvinonyanya kuita seizvi:

Chekutanga, mashandiro emhando inogadziriswa

Zviratidzo zvakawanda zvekushanda kwemuviri uye zvemakanika zvinogona kugadziriswa kuburikidza nekusarudza zvinhu zvakagadzirwa uye mafomura, mukati memhando dzakasiyana dzekuchinja, kuitira kuti zvienderane nezvinodiwa nemushandisi pakushanda kwechigadzirwa.

Chechipiri, kuramba kwakanyanya kwekubvisa
Kana paine mvura, mafuta nezvimwe zvinhu zvinonyorovesa, polyurethane casters haigoni kupfeka zvinhu zvakajairika kakawanda kupfuura rabha. Zvinhu zvesimbi zvakaita sesimbi nezvimwe zvakaoma, asi hazvirevi kuti hazvifaniri kupfeka!

Chechitatu, nzira dzekugadzirisa, kushanda kwakafara
Ma elastomer epolyurethane anogona kuumbwa nerabha rinoshandisa purasitiki, kusanganisa ne vulcanizing (MPU); anogonawo kugadzirwa kuita rabha remvura, kudira nekuumba kana kupfapfaidza, kuvhara nekuumba centrifugal (CPU); anogonawo kugadzirwa kuita zvinhu zvakapwanyika uye mapurasitiki akajairwa nejekiseni, extrusion, calendering, blow molding nedzimwe nzira (CPU). Zvikamu zvakaumbwa kana kuti zvakaiswa jekiseni, mukati meimwe nzvimbo yekuoma, zvinogonawo kuchekwa, kukuyiwa, kuboorwa uye kumwe kugadzirwa kwemuchina.

Chechina, kuramba mafuta, kuramba ozone, kuramba kukwegura, kuramba mwaranzi, kuramba tembiricha yakaderera, kutumirwa kweruzha kwakanaka, simba rakasimba rekunamira, kubatana kwakanaka kwehupenyu uye kuenderana neropa. Mabhenefiti aya ndiwo chaiwo anoita kuti polyurethane elastomers ishandiswe zvakanyanya mumauto, mundege, muacoustics, mubiology nedzimwe nzvimbo.
