Zipangizo za thovu la polyurethane zimagawidwa makamaka m'magulu awiri: thovu lofewa la PU, thovu lolimba la PU, ndi thovu lopopera. Thovu losinthasintha la PU limagwiritsidwa ntchito pazinthu zosiyanasiyana monga kuphimba, kudzaza zovala, ndi kusefa. pomwe thovu lolimba la PU limagwiritsidwa ntchito makamaka pa ma board oteteza kutentha ndi zipangizo zoteteza kutentha zomwe zimagwiritsidwa ntchito popanga nyumba zamalonda ndi nyumba, komanso denga la thovu (lopopera).
Chinthu chomwe tikuyesa lero ndi thovu lofewa la polyurethane, lomwe limagwiritsidwa ntchito makamaka poyamwa ndi kuphimba ma shock.
Chithunzi chakumanzere chikuwonetsa chipika chochepetsera kugwedezeka chomwe chadulidwa kale, ndipo chithunzi chakumanja chikuwonetsa chipika chochepetsera kugwedezeka pambuyo podula.
Kuchokera pazithunzi, zikuwoneka kuti chipika chosadulidwa chonyowa chimakhala ndi ma burrs owoneka bwino komanso guluu wodzaza, ndipo ma burrs amapezeka kwambiri pamalo olumikizirana ndi nkhungu. Gulu la zinthuzi lili ndi kuchuluka komanso kuchuluka, ndipo kudula pamanja sikuti kumatenga nthawi yokha komanso kumakhala kovuta. Chifukwa chake, kasitomala watipatsa udindo wochita kukonza ma cryogenic.
Chogulitsachi chimagwiritsa ntchito makina a NS-180 podula. Makina a 180 ali ndi mphamvu zambiri ndipo ndi oyenera makampani omwe ali ndi zinthu zambiri komanso opanga zinthu zambiri.
Njira yochotsera utoto wa cryogenic sidzakhudza mawonekedwe ndi magwiridwe antchito a chinthucho. Njira yodulira imatenga pafupifupi mphindi 10-15.
Kuyerekeza mawonekedwe a chinthucho chisanachotsedwe ndi pambuyo pake n'koonekeratu. Mtundu wa chinthucho sunasinthe.
STMC Precision yakhala ikuyang'ana kwambiri pa kuyeretsa madzi pogwiritsa ntchito cryogenic deflashing kwa zaka 20. Tikulandira makasitomala onse kuti atiyimbire foni kuti atifunse mafunso!
