Kodi polyethylene ya chlorine ndi chiyani ndi makhalidwe ake:

1. Chlorinated polyethylene, yomwe imadziwikanso kuti CPE mu Chingerezi, ndi mtundu wa polyethylene. Chlorinated polyethylene (CPE) ndi chinthu chomwe chimapezeka posintha pang'ono maatomu a haidrojeni pa polyethylene yapamwamba kwambiri (HDPE) ndi maatomu a chlorine. CPE imawoneka ngati ufa woyera, wopanda poizoni komanso wopanda fungo.
2. Polyethylene yokhala ndi chlorine yopangidwa kuchokera ku polyethylene yotsika mphamvu ya HDPE imakhala yolimba kwambiri ku kutentha kwambiri komanso kukalamba kuposa polyethylene yokhala ndi chlorine yopangidwa kuchokera ku polyethylene yokhala ndi mphamvu yamphamvu yamphamvu. Kawirikawiri, polyethylene yokhala ndi kachulukidwe ka 0.93-0.96g/cm3, kulemera kwapakati kwa mamolekyulu a 50000 mpaka 250000, ndi index yosungunuka pakati pa 0.01 ndi 2.0g/10min imagwiritsidwa ntchito popanga polyethylene yokhala ndi chlorine. Mlingo wa chlorination wa polyethylene yokhala ndi chlorine umakhudza kwambiri mawonekedwe ake. Pamene kuchuluka kwa chlorine kuli kochepera 15%, ndi pulasitiki; Pamene kuchuluka kwa chlorine kuli 16-24%, ndi elastomer ya thermoplastic; Ma elastomer ofanana ndi rabara okhala ndi kuchuluka kwa chlorine pakati pa 25-48%; Pamene kuchuluka kwa chlorine kuli 49-58%, ndi polima wolimba wofanana ndi chikopa; Pamene kuchuluka kwa chlorine kufika pa 73%, kumakhala utomoni wofooka. Kuyika pafupifupi 27% ya chlorine mu polyethylene yopanikizika kwambiri kumachotsa kwathunthu kupangika kwa makristalo, pomwe kuyika pafupifupi 30% ya chlorine mu polyethylene yopanikizika pang'ono yokhala ndi makristalo ambiri kumachotsanso kwathunthu kupangika kwa makristalo. Monga rabara elastomer, kuchuluka kwa chlorine kumakhala bwino mkati mwa 30-40%. Pakadali pano, kuchuluka kwa chlorine mu rabara ya polyethylene yogulitsidwa ndi chlorine kumakhala pakati pa 25-45%. Pamene kuchuluka kwa chlorine kukukwera, kukana mafuta, kupuma, ndi kuchedwa kwa moto kumawonjezeka; Pamene kuchuluka kwa chlorine kukuchepa, kukana kuzizira, kupirira, ndi magwiridwe antchito opindika amakhala bwino.
2. Makhalidwe a Chlorinated Polyethylene CPE
1) CPE ndi rabara yokhuta yokhala ndi kutentha ndi mpweya wabwino kwambiri wotsutsa ukalamba, kukana ukalamba wa ozoni, kukana asidi ndi alkali, komanso mphamvu za mankhwala.
2) CPE ili ndi kukana bwino kwa mafuta, yokhala ndi kukana bwino kwa mafuta a ASTM 1 ndi mafuta a ASTM 2, yofanana ndi NBR; Kukana bwino kwa mafuta a ASTM No. 3, yoposa CR komanso yofanana ndi CSM.
3) CPE ili ndi chlorine element, yomwe ili ndi mphamvu zabwino kwambiri zoletsa moto ndipo ili ndi mphamvu zoyaka komanso zoletsa kudontha kwa madzi. Itha kusakanikirana ndi zoletsa moto zochokera ku antimony, paraffin ya chlorinated, ndi Al (OH) 3 m'njira yoyenera kuti ipeze zinthu zoletsa moto zomwe zimakhala ndi mphamvu zabwino kwambiri zoletsa moto komanso mtengo wotsika.
4) CPE si poizoni, ilibe zitsulo zolemera ndi ma PAH, ndipo imakwaniritsa zofunikira zachilengedwe mokwanira.
5) CPE imakhala ndi mphamvu zambiri zodzaza ndipo imatha kupanga zinthu zomwe zimakwaniritsa zofunikira zosiyanasiyana. CPE imakhala ndi mphamvu zabwino zokonzera zinthu, ndipo pali mitundu yosiyanasiyana yosankha yokhala ndi kukhuthala kwa Mooney pakati pa 50-100.
