HCPE (Rabala ya chlorine)
HCPE (Rabala ya chlorine)
Tinthu tating'onoting'ono toyera tomwe tili ndi kuwala koyera. Popeza kapangidwe ka mamolekyu kamakhala ndi ma bond awiri ndipo maatomu a chlorine amagawidwa mwachisawawa, amakhala ndi kukana kwabwino kwa nyengo, kukana ozoni, kukana kutentha, kukana malawi, kukana mankhwala ndi kukana mafuta. Amagwiritsidwa ntchito m'malo mwa mphira wa chlorine popanga zomatira.
HCPE ingagwiritsidwenso ntchito ngati zomatira, utoto, zoletsa moto, ndi zosinthira inki zapamwamba, zomwe zingathandize kulimbitsa kumatira, kukana dzimbiri, kuletsa moto, komanso kukana kukwiya. Pogwiritsidwa ntchito ngati zinthu zopangira utoto, mphamvu yayikulu yolimbana ndi dzimbiri ndi chloride ion, kotero mukamaliza kugaya nthawi yachilimwe, kutentha kopera kukapitirira 60°C, ndikofunikira kuganizira zoziziritsa kapena kukonza padera yankho loti muwonjezere ku thanki yomalizidwa, chifukwa pa 56°C, chloride ion imachepa. Mphamvu yolimbana ndi dzimbiri ya utoto imachepa, ndipo utoto wolemera wotsutsana ndi dzimbiri umayikidwa.
| Chinthu | HCPE-HML | HCPE-HMZ |

Amagwiritsidwa ntchito m'malo mwa rabara wothira chlorine popanga zomatira. Angagwiritsidwenso ntchito ngati chosinthira zomatira, inki yapamwamba kwambiri ndi zinthu zina, zomwe zingathandize kuti zomatira zikhale zolimba, zotsutsana ndi dzimbiri, zoletsa moto, komanso zosagwirizana ndi kuwonongeka. Sungani m'nyumba yosungiramo zinthu yozizira, yopuma mpweya komanso youma, kutali ndi chinyezi.
Chifukwa cha kapangidwe ka molekyulu kake kokhazikika, kukhuta, polarity yochepa komanso kukhazikika kwa mankhwala kwa mphira wothira chlorine, zokutira zosiyanasiyana zotsutsana ndi dzimbiri zomwe zimapangidwa nazo zimakhala ndi mawonekedwe ouma mwachangu a filimu yokutira, kumamatira bwino, kukana mankhwala komanso kukana bwino kulowa kwa chinyezi.
Polyethylene HCPE yokhala ndi chlorine yambiri imakhala ndi mphamvu yabwino kwambiri yolimbana ndi ukalamba komanso mankhwala osakanikirana, imasungunuka mosavuta mu ma hydrocarbons onunkhira, ma esters, ma ketones ndi zinthu zina zachilengedwe, ndipo imagwirizana bwino ndi utoto wambiri wazinthu zachilengedwe ndi zachilengedwe womwe umagwiritsidwa ntchito mu zokutira. Nthawi zambiri, ndi yoyenera kusungunuka mu resin solution ya 40% yolimba yopaka utoto.
