Kushandiswa kwePVA fiber mukongiri

Abstract:

Polyvinyl doro (PVA) fibers yakabuda sechinhu chinovimbisa chekuwedzera mukongiri tekinoroji, ichibatsira kuvandudza akasiyana emakanika uye kusimba zvivakwa. Iyi ongororo yakazara inoongorora mhedzisiro yekusanganisa PVA fiber mukongiri musanganiswa, kukurukura zvivakwa zvavo, maitiro ekugadzira, uye akasiyana mashandisiro muindasitiri yekuvaka. Hurukuro inosanganisira mhedzisiro yePVA fiber pane nyowani uye yakaomeswa zvimiro zvekongiri, basa radzo mukudzivirira kutsemuka, uye zvingangove zvinobatsira kwezvakatipoteredza zvine chekuita nekushandiswa kwavo. Pamusoro pezvo, matambudziko uye tarisiro yeramangwana zvinoratidzwa kutungamira kumwe kutsvagisa nekusimudzira munharaunda iyi.
