Makhalidwe osiyanasiyana ndi ntchito za CPE chlorinated polyethylene

CPE, Chlorinated polyethylene, yomwe imadziwikanso kuti chlorinated polyethylene, imapangidwa kuchokera ku polyethylene yapamwamba kwambiri (HDPE) kudzera mu njira ya chlorination. Khalidwe la zinthuzi ndilakuti maatomu a haidrojeni omwe ali mu unyolo wake wa mamolekyu amalowedwa m'malo pang'ono ndi maatomu a chlorine, zomwe zimapangitsa kuti pakhale kapangidwe kake ka mankhwala. CPE youma imawoneka ngati ufa woyera ndipo si poizoni komanso yotetezeka. Fomula yake ya mamolekyu ndi CH2-CHCl-CH2-CH2] n, yomwe yafupikitsidwa ngati CPE kapena CM mu Chingerezi. Monga chinthu chodzaza ndi polima, CPE sikuti imangokhala ndi kukana kwabwino kwa nyengo komanso kukana malawi, komanso imawonetsa kukhazikika kwabwino kwa kutentha, komwe ndi kwabwino kwambiri kuposa PVC. Kuphatikiza apo, ilinso ndi zabwino zotsika mtengo komanso magwiridwe antchito abwino. Ponena za kusungunuka, CPE imasungunuka mu aromatic hydrocarbons ndi halogenated hydrocarbons, koma imasungunuka mu aliphatic hydrocarbons. Kutentha kukapitirira 170 ℃, imayamba kuwola ndikutulutsa mpweya wa hydrogen chloride. Chifukwa cha kapangidwe kake kokhazikika ka mankhwala, CPE imakhalanso ndi kukana kwabwino kwa ukalamba, kukana kuzizira, kukana mankhwala, kukana ozone, ndi kutchinjiriza magetsi. Nthawi yomweyo, imagwirizana bwino komanso imatha kukonzedwa bwino, ndipo imatha kusakanikirana ndi zinthu monga PVC, PE, PS, ndi rabara, zomwe zimapangitsa kuti zinthuzi zikhale bwino.
CPE ili ndi ntchito zosiyanasiyana m'magawo osiyanasiyana
1. Kugwiritsa ntchito mu nembanemba yosalowa madzi
Kachidutswa ka PVC kothira madzi ka CPE, komwe kali ndi makhalidwe abwino kwambiri a CPE, kawonjezera mphamvu zake zolimba ndi 80% ndi mphamvu zong'ambika ndi 50%. Nthawi yomweyo, kukana kwake kwa makina nyengo, kukana kutentha pang'ono, komanso kukana kukalamba kwawonjezeredwanso mokwanira, ndipo kamakondedwa kwambiri ndi madipatimenti omanga (ndi CPE yowonjezera yowongoleredwa pa 10% -15%). Kuphatikiza apo, kachidutswa ka CPE kothira madzi ka chloroprene ndi kachidutswa ka CPE kothira madzi ka chloroprene styrene butadiene ka raba kothira madzi kwakhala mbadwo watsopano wa zipangizo zabwino zothira madzi chifukwa cha mphamvu zawo zapamwamba, kusinthasintha kwakukulu, kufalikira kwakukulu, komanso zabwino zambiri monga kukana dzimbiri, kukana kutentha kwambiri, kukana kuzizira, kukana kukalamba, komanso kuchedwa kwa moto, ndipo ali ndi mwayi waukulu pamsika.
2. Kupanga zitseko ndi mawindo apulasitiki
Mwa kusakaniza CPE ndi PVC, kusinthasintha, kulimba, ndi magwiridwe antchito a zitseko ndi mawindo apulasitiki kutentha kochepa kumawonjezeka kwambiri, komanso kumakhala ndi kukana kwabwino kwa nyengo, kukana kutentha, komanso kukhazikika kwa mankhwala. Mtundu uwu wa zitseko ndi zenera la pulasitiki ndi wotsika mtengo, sulimbana ndi dzimbiri, ndipo umabwera mumitundu yosiyanasiyana. Poyerekeza ndi zitseko ndi mawindo a aluminiyamu, uli ndi zabwino zambiri ndipo pang'onopang'ono wakhala wokondedwa watsopano pamsika.
3. Kugwiritsa ntchito waya ndi chingwe
Kuwonjezera kwa CPE kwathandiza kuti cathodic burn performance, anti-ukalamba performance komanso kuti mawaya ndi zingwe zikhale ndi mphamvu komanso makina. Nthawi yomweyo, zipangizo zokutira waya ndi zingwe zopangidwa makamaka ndi CPE zimasonyezanso kuti ndi zabwino kwambiri.
4. Kupanga mapaipi a rabara ndi nsapato
CPE imatha kupanga mapaipi omwe sakhudzidwa ndi mafuta, asidi, kupindika, ozone, ndi Freon, ndipo ndi oyenera kupanga mapaipi a hydraulic, mapaipi ozizira, mapaipi amafuta, ndi zina zambiri. Nthawi yomweyo, chidebe cha ng'ombe chongoyerekeza chopangidwa ndi CPE ngati thupi lalikulu chimasonyezanso magwiridwe antchito abwino kwambiri.
