Ipayipi Lokuvimbela I-Oxygen le-PE-RT II
Isingeniso sepayipi le-PE-RT II Oxygen Barrier
Ipayipi lokuvimba umoya-mpilo lohlobo lwe-GKBM PE-RT (EVOH) liwumkhiqizo othuthukisiwe wepayipi lokushisa phansi le-PERT. Likhiqizwa kusetshenziswa inqubo yokuxhumanisa enezingqimba ezintathu noma ezinhlanu. Ingqimba yangaphakathi (eyezingqimba ezinhlanu iyizingqimba zangaphakathi nezangaphandle) yipayipi le-PE-RT, ingqimba yangaphandle (eyezingqimba ezinhlanu iyizingqimba eziphakathi) iyizinto zokuvimbela umoya-mpilo ze-EVOH, kanti ingqimba ephakathi iyi-hot melt glue. Uhlobo olusha lwepayipi elihlanganisiwe. Ngaphezu kwazo zonke izinzuzo ze-PE-RT, umehluko omkhulu wepayipi lokuvimba umoya-mpilo ukuthi lingavimba ngempumelelo umoya-mpilo ukuthi ungangeni ohlelweni futhi livikele izingxenye zensimbi ohlelweni ekulimaleni kwe-oxidation. Kunemikhiqizo engu-20 isiyonke yamapayipi okuvimba umoya-mpilo wohlobo lwe-PE-RT (EVOH) II, ahlukaniswe ngezincazelo ezi-5 ezivela ku-dn16-dn40.
Ukuhlukaniswa Kwepayipi Lokushisa Phansi le-PE-RT
1. Umehluko omkhulu phakathi kwamapayipi okuvimbela umoya-mpilo ohlobo lwe-PE-RTⅡ kanye namapayipi e-PE-RT, PE-X, PP-R, PE kanye namanye ukuthi uhlobo lwe-PE-RTⅡ luyisigaba sesithathu esihlanganiswe ngokwemvelo sibe yisigaba esisodwa, lapho isigaba se-EVOH sivimba umoya-mpilo. Amanzi noma umoya ongena epayipini wandisa kakhulu impilo yenkonzo yamavalvu ensimbi, amaswishi, amabhoyila, abaqoqi bamanzi kanye nezinye izingxenye zensimbi ohlelweni lonke lwamapayipi ezigugile ngenxa yokubola. Uma ipayipi lokuvimbela umoya-mpilo lisetshenziswa emanzini ompompi, noma ngabe amanzi awagelezi isikhathi eside, ngeke anciphe ngenxa yokubola, futhi amagciwane aphila nge-oxygen awakwazi ukuyikhiqiza.
Ipayipi lodonga le-PE-RT lohlobo lwe-2.PE-RT II linamandla okumelana nokushisa aphezulu.
3. Iphinde ibe nenzuzo yokungahlali endaweni ngemva kokufakwa nokusebenzisa amapayipi e-PE-RT.
4. Iphinde ibe nezinzuzo zokuba ntofontofo ngemva kokufakwa nokusebenzisa amapayipi e-PE-RT.
5. Iphinde ibe nenzuzo yokuthuthukisa indawo ngemuva kokufakwa nokusetshenziswa kwamapayipi e-PE-RT.
6.Iphinde ibe nezinzuzo zokuphila isikhathi eside kwamapayipi e-PE-RT.
7. Iphinde ibe nezinzuzo zokunakekelwa okulula kwamapayipi e-PE-RT.
8. Amapayipi okuvimbela umoya-mpilo nawo anezici ezifanayo nezinye amapayipi okushisa phansi amelana nokushisa okuphezulu: ukumelana ne-asidi, ukumelana ne-alkali, ukumelana nokugqwala, ukumelana nokuguga, okungenabuthi futhi okungenambitheki, okungenagqwala, ukumelana namanzi amancane, okungenakulinganiswa, ukuqhekeka okuvimbela ukubanda, okuvimbela ukuvuza, ukulahlekelwa ukushisa okuncane, ukonga amandla, okuhlanzekile, okunobungani nemvelo, okuguquguqukayo futhi okulula ukugoba, kanye nokuqeda ukucindezeleka kokugoba okubandayo.
