PVC utomoni kwa matabwa pulasitiki extrusion,
PVC CIF India, PVC K67, PVC utomoni kwa extrusion,
Tsatanetsatane wa malonda
PVC ndi chidule cha polyvinyl chloride.Utomoni ndi zinthu zomwe zimagwiritsidwa ntchito nthawi zambiri popanga mapulasitiki ndi mphira.PVC resin ndi ufa woyera womwe umagwiritsidwa ntchito popanga thermoplastics.Ndi zinthu zopangidwa zomwe zimagwiritsidwa ntchito kwambiri padziko lapansi masiku ano.Utoto wa polyvinyl chloride uli ndi mawonekedwe abwino kwambiri monga zopangira zambiri, ukadaulo wopanga okhwima, mtengo wotsika, komanso ntchito zosiyanasiyana.Ndiosavuta pokonza ndipo akhoza kukonzedwa ndi akamaumba, laminating, jekeseni akamaumba, extrusion, calendering, kuwomba akamaumba ndi njira zina.Ndi katundu wabwino wakuthupi ndi mankhwala, amagwiritsidwa ntchito kwambiri m'makampani, zomangamanga, ulimi, moyo watsiku ndi tsiku, kulongedza katundu, magetsi, zofunikira za boma, ndi zina.Ma resin a PVC nthawi zambiri amakhala ndi kukana kwambiri kwamankhwala.Ndi yamphamvu kwambiri ndipo imagonjetsedwa ndi madzi ndi abrasion.Polyvinyl chloride resin (PVC) imatha kusinthidwa kukhala zinthu zapulasitiki zosiyanasiyana.PVC ndi mapulasitiki opepuka, otsika mtengo, komanso osamalira chilengedwe.
Mawonekedwe
PVC ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi thermoplastic resins.Itha kugwiritsidwa ntchito kupanga zinthu zolimba kwambiri komanso zolimba, monga mapaipi ndi zokokera, zitseko zojambulidwa, mazenera ndi mapepala onyamula.Itha kupanganso zinthu zofewa, monga mafilimu, mapepala, mawaya amagetsi ndi zingwe, matabwa apansi ndi zikopa zopangira, powonjezera mapulasitiki.

Mapangidwe a chilinganizo amachokera ku ntchito ya mankhwala, zipangizo zopangira ndi zothandizira, ndondomeko yowumba ndi zida.Iyi ndi ntchito yovuta komanso yotopetsa, kuti mukhale otetezeka, kawirikawiri pokhapokha pamaziko a chilinganizo choyambirira chokhwima malinga ndi zomwe zinachitikira kusintha kwazing'ono, ndiyeno kupyolera mu mayesero kuti mudziwe njira yabwino kwambiri yomwe ikugwirizana ndi zofunikira.Wolembayo amachokera pa ndondomeko ya zitseko za PVC wamba ndi mbiri ya Windows, kuwonjezera ufa wa nkhuni, wotulutsa thovu, wotulutsa thovu, wothandizira kupaka utoto, ndiyeno malinga ndi mayeso a orthogonal. kudziwa kuchuluka kwa mitundu yosiyanasiyana yaiwisi ndi zothandizira.
Kuwonjezera kwa ufa wa nkhuni kumapangitsa kuti kutuluka kwa zinthuzo zikhale zovuta kwambiri.Ndi kuwonjezeka kwa zomwe zili mu ufa wa nkhuni, nthawi ya pulasitiki imakulitsidwa, ndipo madzi amadzimadzi amakhala ochepa komanso ochepa. , ufa wa nkhuni udzagonjetsedwa ndi mphamvu yometa ubweya wambiri, kuonjezera nthawi yokhalamo mu extruder, kotero kuti ufa wa nkhuni umakhala wosavuta kuwotcha, osati wothandiza kutulutsa; zidzachititsanso mphamvu kupunduka ndi pamwamba zilema za product.Choncho, mu ndondomeko extrusion, rheological katundu wa dongosolo zimakhudza kwambiri machining ndondomeko ndi katundu wa chomaliza product.Table 2 limasonyeza processing katundu wa kompositi ndi zosiyanasiyana. chakudya cha nkhuni.
Chifukwa cha kukula kwa tinthu tating'ono komanso kachulukidwe kakang'ono ka ufa wa nkhuni womwe umagwiritsidwa ntchito poyesa, kuchuluka kwamafuta a nkhuni mu dongosolo kumawonjezeka ndi kuchuluka kwa kudzaza, komanso mphamvu ya adsorption ya lubricant, plasticizer ndi zowonjezera zowonjezera. ndi lalikulu.Ngakhale ndondomeko processing akhoza kutulutsa lalikulu kukangana kutentha kufulumizitsa plasticizer, koma sikokwanira kuthetsa chifukwa plasticizer, processing zina ndi zina adsorbed plasticizer liwiro kuchepetsa mphamvu ya plasticizer nthawi, kuti plasticizer delay.The zokulirapo zili ufa nkhuni, m'pamenenso processing AIDS odzipereka, amene adzawonjezera plasticizing nthawi, osauka processing performance.The kutsimikiza komaliza kusankha nkhuni ufa zili 30.
