PVC utomoni chimagwiritsidwa ntchito m'mafakitale osiyanasiyana.Malinga ndi digiri ya polymerization ya utomoni wa PVC, kuuma kwake kumasiyananso.
Mbiri ya PVC
Mbiri ndi mbiri ndi madera omwe amamwa kwambiri PVC ku China, omwe amawerengera pafupifupi 25% ya ma PVC onse.Amagwiritsidwa ntchito makamaka kupanga zitseko ndi mazenera ndi zipangizo zopulumutsa mphamvu.Kugwiritsa ntchito kwawo kukukulirakulirabe m'dziko lonselo.M'mayiko otukuka, gawo la msika la zitseko ndi mawindo apulasitiki ndilopamwamba kwambiri, monga 50% ku Germany, 56% ku France ndi 45% ku United States.
Chithunzi cha PVC
Pakati pazinthu zambiri za PVC, chitoliro cha PVC ndi gawo lachiwiri lalikulu kwambiri, lomwe limawerengera pafupifupi 20% yazakudya zake.Ku China, chitoliro cha PVC chimapangidwa kale kuposa chitoliro cha PE ndi chitoliro cha PP, chokhala ndi mitundu yambiri, magwiridwe antchito abwino komanso osiyanasiyana ogwiritsa ntchito, omwe ali ndi malo ofunikira pamsika.
PVC nembanemba
Kugwiritsidwa ntchito kwa PVC m'munda wa PVC membrane kumakhala kwachitatu, kuwerengera pafupifupi 10%.Pambuyo pa PVC ndi kusakaniza ndi pulasitiki ndi zowonjezera, filimu yowonekera kapena yamitundu yokhala ndi makulidwe apadera amapangidwa ndi mpukutu atatu kapena kalendala inayi.Filimuyi imakonzedwa ndi njira iyi kuti ikhale filimu ya kalendala.Mukhozanso kudula ndi kutentha chisindikizo ma CD matumba, raincoats, tablecloths, makatani, zoseweretsa inflatable, etc. lonse mandala filimu angagwiritsidwe ntchito kwa wowonjezera kutentha, pulasitiki wowonjezera kutentha ndi pulasitiki filimu.Kanema wotambasulidwa wa biaxially ali ndi mawonekedwe a kutsika kwamafuta ndipo atha kugwiritsidwa ntchito popangira ma shrinkage.
PVC zolimba ndi mbale
PVC imawonjezeredwa ndi stabilizer, lubricant ndi filler.Pambuyo kusakaniza, mapaipi olimba, mapaipi ooneka ngati apadera ndi mapaipi a malata amitundu yosiyanasiyana amatha kutulutsidwa ndi extruder kwa downcomer, chitoliro cha madzi akumwa, malaya a waya kapena masitepe.Mapepala a kalendala amatha kupindika ndikuwotcha kuti apange mbale zolimba za makulidwe osiyanasiyana.mbale akhoza kudula mu mawonekedwe chofunika, ndiyeno welded mu akasinja zosiyanasiyana dzimbiri zosagwira mankhwala, mpweya ducts ndi muli ndi PVC elekitirodi ndi mpweya wotentha.
PVC general soft products
Iwo akhoza extruded mu hoses, zingwe, mawaya, etc. ndi extruder;Nsapato za pulasitiki, ma soles, slippers, zoseweretsa, mbali zamagalimoto, ndi zina zitha kupangidwa ndi makina opangira jekeseni okhala ndi zisankho zosiyanasiyana.
PVC ma CD zipangizo
Zogulitsa za PVC zimagwiritsidwa ntchito kwambiri kunyamula zotengera zosiyanasiyana, makanema ndi zidutswa zolimba.Zotengera za PVC nthawi zambiri zimatulutsa madzi amchere, mabotolo a zakumwa ndi zodzikongoletsera, ndipo amagwiritsidwanso ntchito kuyika mafuta oyengeka.PVC filimu angagwiritsidwe ntchito kwa CO extrusion ndi ma polima ena kupanga otsika mtengo mankhwala laminated ndi zinthu mandala ndi chotchinga chabwino.PVC filimu Angagwiritsidwenso ntchito kutambasula kapena kutentha shrinkable ma CD, ndi ma CD matiresi, nsalu, zidole ndi katundu mafakitale.
PVC khoma mapanelo ndi pansi
Pvc khoma mapanelo makamaka ntchito m'malo aluminiyamu khoma mapanelo.Kuphatikiza pa mbali ya PVC utomoni, zigawo zina za PVC matailosi pansi ndi zipangizo zobwezerezedwanso, zomatira, fillers ndi zigawo zina, amene makamaka ntchito pansi pa bwalo la ndege ma terminal ndi nthaka yolimba m'malo ena.
PVC ogula katundu
Chikwama chonyamula katundu ndi chinthu chachikhalidwe chopangidwa ndi PVC.PVC imagwiritsidwa ntchito popanga mitundu yonse ya zikopa, thumba lachikwama ndi zinthu zamasewera, monga basketball, mpira ndi mpira.Itha kugwiritsidwanso ntchito kupanga mayunifolomu ndi malamba a zida zapadera zodzitetezera.Nsalu za PVC zopangira zovala nthawi zambiri zimakhala nsalu zoyamwa (zopanda zokutira), monga ma poncho, mathalauza amwana, ma jekete achikopa oyerekeza ndi nsapato zamvula zosiyanasiyana.Polyvinyl chloride imagwiritsidwa ntchito pazinthu zambiri zamasewera ndi zosangalatsa, monga zoseweretsa, zolemba ndi zinthu zamasewera.Zoseweretsa za polyvinyl chloride ndi zinthu zamasewera zimakhala ndi kukula kwakukulu.Ili ndi mwayi chifukwa cha mtengo wake wotsika mtengo komanso kuumba kosavuta.
Zinthu zopangidwa ndi PVC
Chikopa chopanga chokhala ndi gawo lapansi chimapangidwa pogwiritsa ntchito PVC pansalu kapena pepala ndikuyika pulasitiki pamwamba pa 100 ℃.PVC ndi zowonjezera zimathanso kusinthidwa kukhala filimu, kenako kukanikizidwa ndi gawo lapansi.Chikopa chochita kupanga chopanda gawo lapansi chimasinthidwa mwachindunji kukhala mapepala ofewa a makulidwe ena ndi kalendala, ndiyeno amapanikizidwa ndi machitidwe.Zikopa zopangira zingagwiritsidwe ntchito popanga masutukesi, zikwama, zophimba mabuku, sofa ndi ma cushioni agalimoto, komanso zikopa zapansi, zomwe zitha kugwiritsidwa ntchito ngati zida zopangira nyumba.
Zinthu zopangidwa ndi thovu la PVC
Pamene PVC yofewa imasakanizidwa, muyeso woyenera wa thovu umawonjezeredwa mu pepala kuti mupange pulasitiki ya thovu, yomwe ingagwiritsidwe ntchito ngati thovu, nsapato, insoles, ndi zipangizo zonyamula katundu zogwedeza.Itha kupangidwanso kukhala mbale za PVC zotsika thobvu zolimba ndi mbiri zochokera ku extruder, zomwe zimatha m'malo mwa nkhuni.Ndi chinthu chatsopano chomangira.
PVC transparent pepala
PVC imasakanizidwa, yopangidwa ndi pulasitiki ndikusinthidwa kukhala pepala lowonekera powonjezera kusintha kwamphamvu ndi organotin stabilizer.Thermoforming itha kugwiritsidwa ntchito kupanga zotengera zowoneka bwino zokhala ndi mipanda kapena vacuum matuza.Ndizinthu zabwino kwambiri zopangira ma CD ndi zinthu zokongoletsera.
Ena
Zitseko ndi mazenera amasonkhanitsidwa ndi zida zolimba zooneka ngati zapadera.M'mayiko ena, yatenga msika wa zitseko ndi mazenera pamodzi ndi zitseko zamatabwa, mazenera ndi mazenera a aluminiyamu;Kutsanzira zipangizo zamatabwa ndi zomangira zitsulo (Kumpoto ndi m'mphepete mwa nyanja);Chidebe chopanda kanthu.
Virtual circuit ndi imodzi mwazinthu zomwe zimaperekedwa ndi packet switching network (inayo ndi datagraph service).Mwachidule, ndikukhazikitsa kulumikizana koyenera pakati pa makamu ogwiritsa ntchito kudzera munjira yowongolera mkati mwa netiweki, ndikuwonetsetsa kulondola ndi kutsatizana kwapaketi yotumizira.Dera la Virtual liyenera kukhazikitsidwa ndikuchotsedwa musanayambe komanso mutatha kulumikizana.Permanent virtual circuit ndi dera lomwe limakhazikitsidwa panthawi yoyambitsa maukonde, ndipo dera lozungulira limasungidwa nthawi zonse.
