Kodi pali kusiyana kotani pakati pa polyethylene yokhala ndi chlorine yambiri ndi rabara yokhala ndi chlorine?

Polyethylene yokhala ndi chlorine yambiri (HCPE) ndi rabara yokhala ndi chlorine (CR) yopangidwa ndi Bontecn Group China ndi ma polima awiri omwe amagwiritsidwa ntchito kwambiri m'magawo a zomatira zotsutsana ndi dzimbiri, koma ali ndi kusiyana kwakukulu pa kapangidwe ka mankhwala, mawonekedwe a ntchito, ndi zochitika zomwe zingagwiritsidwe ntchito.
1. Kapangidwe ka mankhwala ndi ubwino wa chilengedwe
HCPE: Yokonzedwa mwa kusintha kwa chlorination ya polyethylene, yokhala ndi maatomu a chlorine mwachisawawa komanso kuchuluka kwa chlorine komwe nthawi zambiri kumakhala ≥ 65%. Yopangidwa ndi njira yoyimitsira madzi, ilibe kuipitsa kwa solvent ndipo imakwaniritsa zofunikira zoteteza chilengedwe.
CR: Imapangidwa ndi chlorine kuchokera ku rabara lachilengedwe kapena rabara lopangidwa, yokhala ndi chlorine yokwanira pafupifupi 60-65%. Kupanga zosungunulira zachilengedwe kungayambitse zinthu zotsalira zovulaza komanso kuteteza chilengedwe molakwika.
2. Kuyerekeza magwiridwe antchito
Kukana kwa nyengo: HCPE ili ndi kukana kwa ozone ndi ultraviolet kwapamwamba, zomwe zimapangitsa kuti ikhale yoyenera malo okhala panja kwa nthawi yayitali monga milatho ndi sitima; CR imatha kuwonongeka kutentha kwambiri ndipo imakhala ndi kukana kofooka kwa nyengo.
Kukana mankhwala: Zonsezi ndi zolimbana ndi asidi ndi alkali, koma HCPE imapirira kwambiri ma oxidant amphamvu (monga sulfuric acid yokhazikika), popanda kutupa kapena kutayika pambuyo pa masiku 30 a mayeso.
3. Kusiyana kwa magawo ogwiritsira ntchito
HCPE:
Chophimba cholimba choletsa dzimbiri (zipangizo za mankhwala, mapaipi amafuta)
Zipangizo zoletsa moto (zophimba moto, zingwe zotchingira)
Guluu wapamwamba kwambiri (wogwirizira ndi PVC ndi chitsulo)
CR:
Zophimba zachikhalidwe zoletsa dzimbiri (za zombo ndi zotengera)
Inki ndi munda wosindikizira
4. Msika ndi Mtengo
HCPE: Chifukwa cha mtengo wokwera wa njira zotetezera chilengedwe koma magwiridwe antchito abwino, pang'onopang'ono ikusintha CR.
CR: Mtengo wake ndi wotsika, koma chifukwa cha malamulo okhudza chilengedwe, ntchito yake ndi yochepa.
5. Kugwiritsa ntchito kothandiza
Zonsezi zimagwirizana ndi ma resin ena monga epoxy resin ndi acrylic acid, koma HCPE ndi yoyenera kwambiri pamakina opaka utoto omwe amafunikira kumamatira kwambiri kapena kukana nyengo.
