ntchito

M'kati mwa kupanga PVC, chifukwa cha ndondomeko yoyendetsera ndondomeko ya ndondomeko ya ndondomeko ndi zinthu zina, mtundu womwewo wa PVC wopangidwa ndi makampani osiyanasiyana (mtundu wa SG5 mwachitsanzo) mu ntchitoyo ndi wosiyana Kwa makampani opanga PVC, nthawi zambiri amakhala ofanana. Nthawi yogwiritsira ntchito zinthu zingapo, ndi makampani osiyanasiyana popanga PVC pakusiyana kwa magwiridwe antchito (ngakhale ang'onoang'ono), amafunikira mabizinesi opangira zinthu popanga njira yosinthira, PVC, kapenanso njira yomweyo yamakampani osiyanasiyana ingawonekere processing kupanga khalidwe vuto Choncho, kwa PVC processing mabizinezi, kumvetsa magawo ntchito ya aliyense PVC, zikhoza kupangidwa malinga ndi makhalidwe ntchito ya mankhwala ake, kupewa debugging akhungu chifukwa cha kuwononga chuma Pakuti PVC kupanga mabizinesi, kumvetsa kampani. kupanga PVC ndi makampani ena mu kusiyana magwiridwe ntchito, akhoza kuunikira mphamvu zawo, kubwezera zofooka zawo, kupanga mankhwala mikhalidwe mpikisano msika, wolemba yekha zoweta AB c DE opanga PVC pa kukhuthala koonekera kwa kusungunula zikuoneka kuyezetsa ntchito. Pakuyesa, wolemba kwathunthu mogwirizana ndi mfundo yofunafuna chowonadi kuchokera ku zowona, kuyesa koyenera komanso koyenera, malinga ndi chiphunzitso choyambirira cha PVC processing, magwiridwe antchito amafananizidwa.

(1) PVC yopangidwa ndi Factory C ili ndi mamasukidwe apamwamba kwambiri.The apamwamba mamasukidwe akayendedwe, zovuta PVC utomoni plasticizing, ndi zovuta processing;Kukhuthala kotsika kwambiri ndi A, B, E fakitale yopangidwa ndi PVC, kukhuthala ndi otsika, utomoni wa PVC ndi wosavuta kupangira pulasitiki, wosavuta kukonza.

(2) Kachulukidwe kowoneka bwino ka PVC kopangidwa ndi fakitale B ndi yayikulu, ndipo yopangidwa ndi fakitale E ndiyo yaying'ono kwambiri.Pokonza utomoni wa PVC, tinthu tating'onoting'ono ta utomoni wa PVC (ndiko kuti, kuchulukitsidwa kowoneka bwino), zinthu zopangidwa mopepuka komanso "diso lansomba" limakhala locheperako, losavuta kukonza.

(3) Kuchuluka kwa mayamwidwe a plasticizer kunali kwakukulu mu PVC opangidwa ndi fakitale C ndi yaying'ono kwambiri mu PVC yopangidwa ndi fakitale B. The kuchuluka kwa mayamwidwe plasticizer, PVC utomoni mu ndondomeko kusanganikirana n'zosavuta kuyamwa plasticizer, lubricant ndi zina. processing zina, khalidwe la osakaniza ndi zabwino, processing ake kusungunuka ntchito ndi bwino.

(4) Chiwerengero cha “maso ansomba” opangidwa ndi fakitale B ndicho PVC chochuluka."Fisheye" ndi akamanena za polymerization ndondomeko chifukwa cha zinthu zosayenera ndi mapangidwe pang'ono maselo kamangidwe ka polima PVC, amene n'zovuta plasticize mu ndondomeko ya PVC processing, zimakhudza kwambiri khalidwe mankhwala, kotero zochepa. chiwerengero cha "fisheye" bwino.

(5) Kuchokera pakuwona nthawi yokhazikika yamafuta, PVC yopangidwa ndi fakitale B ili ndi nthawi yayitali kwambiri yokhazikika, pomwe PVC yopangidwa ndi fakitale D ili ndi nthawi yayitali kwambiri yokhazikika.Kukhazikika kwamafuta a utomoni kumakhudza mwachindunji kukonza kwa zinthu, makamaka pazinthu zolimba.Pofuna kupewa kuwonongeka kwa PVC pakukonza, onjezerani nthawi yokonza, muyenera kusintha mlingo wa stabilizer mu chilinganizo molingana ndi kukhazikika kwake.
