PVC mphamvu chitoliro zopangira
PVC mphamvu chitoliro zopangira,
PVC kwa chitoliro chamagetsi, pvc utomoni kwa chitoliro,
Chitoliro champhamvu cha PVC ndi njira yokonzekera imaphatikizapo zinthu zotsatirazi:
100 polyvinyl kolorayidi utomoni,
15-25 calcium carbonate,
5-10 titaniyamu okusayidi,
4-8 kusintha kosintha,
2-5 stabilizer,
0.5-2 mafuta,
2-4 sepiolite
3 ~ 8 composite inorganic flame retardant agent, composite inorganic flame retardant from osowa earth hydroxide aluminium hydroxide Njira yokonzekera magnesium hydroxide ndi zinc borate
Njira yopangira:
1) Onjezani calcium carbonate titanium oxide mu POLYvinyl chloride resin ndikusakaniza pa liwiro lalikulu kwa 3-6min;2) Kenako onjezani chosinthira chokhazikika, mafuta a sepiolite ndi composite inorganic flame retardant mu osakaniza.
Kutentha kosakaniza ndi 100-110, ndipo nthawi yosakaniza ndi mphindi 10-15.Pambuyo kusakaniza kusakanikirana, kusakaniza kumasamutsidwa ku chosakaniza chozizira pa liwiro lotsika la 40 ~ 50 kwa mphindi 3-5, ndipo potsirizira pake mu conical twin screw extruder pa 170 ~ 190 Chubu chamagetsi chamagetsi chimakhala ndi mphamvu yabwino yochepetsera moto ndipo makina katundu
Polyvinyl Chloride (PVC) ndi mzere wa thermoplastic utomoni wopangidwa ndi polymerization wa vinyl chloride monomer.Chifukwa cha kusiyana kwa zipangizo, pali njira ziwiri za synthesizing vinilu kolorayidi monomer kashiamu carbide ndondomeko ndi mafuta ndondomeko.Sinopec PVC itengera njira ziwiri zoyimitsidwa, motsatana kuchokera ku Japan Shin-Etsu Chemical Company ndi American Oxy Vinyls Company.Chogulitsacho chili ndi kukana kwa dzimbiri kwamankhwala, katundu wabwino kwambiri wamagetsi wamagetsi komanso kukhazikika kwamankhwala abwino.Pokhala ndi klorini wambiri, zinthuzo zimakhala ndi mphamvu zochepetsera moto komanso zozimitsa zokha.PVC ndi yosavuta pokonza ndi extrusion, jekeseni akamaumba, calendering, kuwomba akamaumba, compressing, kuponya akamaumba ndi akamaumba matenthedwe, etc.
Kugwiritsa ntchito
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 ndi zikopa zopangira, powonjezera mapulasitiki.
