Ubwino ndi ntchito za polyethylene yokhala ndi chlorine yambiri HCPE

1. Ubwino waukulu
Kukana nyengo ndi kukana dzimbiri: HCPE ili ndi kapangidwe kokhazikika ka mamolekyulu, kufalikira mwachisawawa kwa maatomu a chlorine, ndipo imatha kukana dzimbiri kuchokera ku UV, ozoni, asidi, alkali, mchere ndi mankhwala ena, zomwe zimapangitsa kuti ikhale yoyenera malo ovuta.
Kulephera kwa moto: Imatha kudzimitsa yokha patatha masekondi 15 ikuyaka, ikukwaniritsa zofunikira pa chitetezo cha moto.
Kulimba kwa kutentha kochepa: kumasunga kusinthasintha ngakhale pa minus 30 ℃, koyenera kugwiritsidwa ntchito m'malo ozizira.
Kusamalira chilengedwe: sikuli poizoni komanso kopanda fungo, komanso kuipitsa pang'ono panthawi yopanga, mogwirizana ndi miyezo ya zinthu zobiriwira.
2. Ntchito zazikulu
(1) Malo oteteza dzimbiri
Monga maziko, imagwiritsidwa ntchito ngati chophimba choletsa dzimbiri cha zombo, milatho, zida zamakemikolo, ndi zina zotero. Sizimakhudzidwa ndi madzi, mafuta, asidi, alkali, mchere, ndi dzimbiri la mumlengalenga, zimakhala zolimba kwambiri, ndipo zimakhala zosavuta kusamalira (zophimba zatsopano ndi zakale zimatha kusakanikirana).
(2) Kusakaniza ndi Kusintha kwa Inki
Zomatira: Zomatira zambiri za HCPE-H zimatha kulowa m'malo mwa zomatira za vinyl chloride ndipo zimagwiritsidwa ntchito polumikiza mapaipi a PVC ndi zinthu zachitsulo. Zikasungunuka mu zosungunulira monga toluene, zimapanga yankho la zomatira zolimba kwambiri.
Inki: imawonjezera kukana kukalamba, kukana dzimbiri, komanso kuchedwa kwa malawi, yoyenera kusindikizidwa kwapamwamba.
(3) Ntchito zina zamafakitale
Monga chosinthira mphamvu ya PVC, chimawonjezera kulimba kwa zinthu zapulasitiki.
Amagwiritsidwa ntchito pa zingwe zolumikizira chingwe, zinthu za rabara (monga mapayipi, matepi), ndi kusintha zinthu zamaginito.
3. Kugawa katundu ndi ma CD
HCPE-H: Kukhuthala kwakukulu, 25kg/thumba, komwe kwapangidwira makamaka zomatira za PVC.
HCPE-M: Kukhuthala kwapakati, komwe kumagwiritsidwa ntchito popaka utoto wotsutsana ndi dzimbiri/wosapsa ndi moto.
HCPE-L: Yochepa kukhuthala, imagwirizana ndi utomoni wa acrylic, yoyenera kuteteza mapaipi apansi panthaka.
