Pamusoro pechinhu ichi
Imba Yakakosha - Yakakwana kushandisa maoko pazviitwa zvemumba zvakaita sekuwacha ndiro, kuchenesa, kuchengeta vakwegura, kuronga maruva nezvimwe.
Kudzivirirwa KweSleeve Yakareba - Yemhando yepamusoro uye isina Mvura PVC zvinhu zvine maruva patani pane yakatambanudzwa ruoko nzvimbo yemagurovhosi.
Polyvinyl chloride (PVC) ndiyo inotanga vinyl chloride monomer (VCM) mu peroxide, azo compounds, etc. yevinyl chloride inonzi vinyl chloride resins.
PVC yeamorphous chimiro cheupfu chena, branched dhigirii idiki, yakaenzana density 1.4, girazi shanduko tembiricha ye77 ~ 90℃, 170℃kana kuti zvakatanga kuora, kusagadzikana kusina kunaka pakupisa uye chiedza, mune zvinopfuura 100℃kana zuva kwenguva yakareba, richaora uye rinogadzira hydrogen chloride, uyezve otomatiki catalytic decomposition, kukonzera discoloration, yemuviri uye michina zvimiro zvakare zvakadonha nekukurumidza, Mukuita, stabilizers dzinofanira kuwedzerwa kuvandudza kupisa uye kugadzikana kwechiedza.
Huremu hwePVC hunogadzirwa neindasitiri hunowanzo pakati pe50,000 ~ 110,000, iine polydispersity yakakura, uye huremu hwemamorekuru hunowedzera nekudzikiswa kwekupisa kwepolymerization; Hapana yakanyunguduka, 80 ~ 85.℃kupfava, 130℃kune viscoelastic state, 160 ~ 180℃kuchinja kuita viscous flow state;Ine yakanaka mechanical zvivakwa, tensile simba ingangoita 60MPa, kukanganisa simba re5 ~ 10kJ/m2; Yakanakisa dielectric zvivakwa.
PVC yaimbove kugadzirwa kwepasirese kwepasi rose-chinangwa mapurasitiki, anoshandiswa zvakanyanya.Inoshandiswa zvakanyanya mukuvaka, zvigadzirwa zvemaindasitiri, zvinodiwa zvezuva nezuva, dehwe repasi, tile yepasi, dehwe rekugadzira, pombi, waya netambo, kurongedza firimu, bhodhoro. , zvinhu zvinopupuma, zvinhu zvekuisa chisimbiso, fiber zvichingodaro.
