I-HDPE QHM32F HDPE-RF yepayipi yokushisisa yaphansi
I-QHM32F i-polyethylene resin ene-hexene-1 njenge-co-monomer ekhiqizwa inqubo ye-Unipol yase-UCC, e-USA.Inezinzuzo zokuguquguquka okuhle, ukusebenza kahle kokucubungula, ukuzinza okushisayo nokumelana nokucindezela.Ikakhulukazi esetshenziselwa ukukhiqizwa kwepayipi lokushisa phansi, i-aluminium - ipayipi yeplastiki eyinhlanganisela, ishubhu yelanga.
Ipayipi le-PE-RT wuhlobo olusha lwe-non-crosslinked polyethylene engasetshenziswa epayipini lamanzi ashisayo.Kuyi-copolymer ye-ethylene ne-octene ekhiqizwe umklamo okhethekile wamangqamuzana kanye nenqubo yokuhlanganisa, enenombolo elawulekayo yeketango legatsha kanye nesakhiwo sokusabalalisa sezinhlobo ze-polyethylene.Isakhiwo samangqamuzana esiyingqayizivele senza izinto ezibonakalayo zibe nokumelana okuhle kakhulu kokuqhekeka kwengcindezi namandla esikhathi eside we-hydrostatic.Ipayipi le-PE-RT linokuguquguquka okuhle, futhi i-modulus yayo yokugoba ingu-550 MPa, futhi ingcindezi yangaphakathi ekhiqizwa ukugoba iphansi.Ngale ndlela, kugwenywa ukuthi ipayipi ingase yonakaliswe endaweni yokugoba ngenxa yokugxila kokucindezeleka.Uma yakhiwe (ikakhulukazi ebusika), ayidingi amathuluzi akhethekile noma ukushisa ukuze igobe.I-Thermal conductivity engu-0. 4 W/ (m·k), uma kuqhathaniswa neshubhu le-PE-X, ephakeme kakhulu kune-PP-R 0. 22 W/ (m·k) kanye ne-PB 0. 17 W/ (m·k), best conductivity ezishisayo, efanelekayo floor bafudumale ipayipi
Isicelo
I-QHM32F iyinhlaka ekhethekile yepayipi le-PE-RT ekhiqizwa i-Qilu Branch yaseSinopec isebenzisa ubuchwepheshe be-Unipol.Umkhiqizo unokuguquguquka okuhle, ukusebenza okuhle kakhulu kokucubungula, ukuzinza okushisayo nokumelana nokucindezela, okungahlangabezana nezidingo zokucubungula ipayipi lesivinini esikhulu sokudonsa imishini ehlukene yokucubungula kanye ne-caliber, futhi ingasetshenziselwa ukukhiqizwa kwepayipi lokushisa phansi, i-aluminium composite yepulasitiki. ipayipi, ipayipi likawoyela, njll.
