PVC utomoni wopangira leater
PVC utomoni kwa kupanga leater,
PVC kwa Synthetic chikopa, PVC Chikopa zopangira, PVC utomoni zikopa,
Nsalu zachikopa za PVC ndizofanana kwambiri ndi nsalu zachikopa za PU.M'malo mwa polyurethane, nsalu ya chikopa ya PVC imapangidwa pophatikiza polyvinylchloride ndi zolimbitsa thupi (kuteteza), mapulasitiki (kuti afewetse) ndi mafuta odzola (kuti azitha kusinthasintha), kenako ndikuyika kuzinthu zoyambira.
Chikopa chopangidwa ndi PVC ndi njira yayikulu yosinthira chikopa chenicheni.Amapangidwa posintha gulu la haidrojeni ndi gulu la chloride mu gulu la vinyl.Izi zimaphatikizidwa ndi mankhwala kuti apange zikopa zopangira.Zopangira zazikulu zomwe zimagwiritsidwa ntchito pochita izi ndi PVC.Chikopa chopangidwa ndi PVC chinali chikopa choyamba chopangidwa mu 1920s.Amaonedwa kuti ndi amphamvu kwambiri komanso otsutsana ndi nyengo zosiyanasiyana.Ndichinthu chosavuta kusamalira komanso choyera motero chimakondedwa kwambiri m'mafakitale osiyanasiyana.
Njira yopangira zikopa za PVC
1.njira yoyamba ndi calendering njira.
kotero choyamba tiyenera kusakaniza zopangira PVC ndi pigment etc, ndi kupanga zakuthupi mu mawonekedwe abwino olimba.
2.kenako tidapaka zinthu zosakanizika pansaluyo,mpaka njira iyi yomaliza yomwe timayitcha kuti maziko.
kotero zinthu zoyambira kuphatikiza zigawo 2: pvc wosanjikiza pamwamba ndi kumbuyo ndi nsalu.
ndiye zinthu zoyambira zidzatumizidwa ku makina otulutsa thovu, omwe ndi mzere wautali wopanga komanso kutentha kwambiri, zinthu zosakanizika zimatulutsa thovu pano, kotero kuti pvc idzakhala yokulirapo, makulidwe a pvc wosanjikiza amatha kuwirikiza kawiri pvc wosanjikiza.
Pambuyo pochita thovu, zinthuzo zidzakongoletsedwa ndi mawonekedwe, apa timagwiritsa ntchito embossing roller yomwe ili ndi mawonekedwe pa chodzigudubuza, mukhoza kuganiza kuti ngati nkhungu, mawonekedwe pa roller adzasamutsidwa pamwamba pa pvc wosanjikiza, ndiye tikhoza kukhala ndi zosiyana. kapangidwe.
ndiye tidzachita mankhwala pamwamba, monga kusintha mtundu kapena kusindikiza zojambula zina pamwamba.
m'munsimu ndi kutuluka kwa chikopa cha pvc
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.Ikhozanso kupanga zinthu zofewa, monga mafilimu, mapepala, mawaya amagetsi ndi zingwe, mapepala apansi ndizikopa zopangidwa, powonjezera mapulasitiki
