I-HDPE QHM32F HDPE-RF yoMgangatho wokufudumeza umbhobho
I-QHM32F i-polyethylene resin ene-hexene-1 njenge-co-monomer eveliswa yinkqubo ye-Unipol yase-UCC, eU.SA.Ineenzuzo zokuguquguquka okuhle, ukusebenza kakuhle kokusebenza, ukuzinza kwe-thermal kunye nokumelana noxinzelelo.Ikakhulu isetyenziselwa ukuveliswa kombhobho wokufudumeza umgangatho, i-aluminium - umbhobho weplastiki odibeneyo, ityhubhu yelanga.
Umbhobho we-PE-RT luhlobo olutsha lwe-non-crosslinked polyethylene engasetyenziswa kumbhobho wamanzi ashushu.I-copolymer ye-ethylene kunye ne-octene eveliswa yi-molecular design ekhethekileyo kunye nenkqubo ye-synthesis, kunye nenani elilawulekayo le-branched chain kunye nesakhiwo sokusabalalisa iintlobo ze-polyethylene.Isakhiwo esikhethekileyo se-molekyuli senza ukuba izinto eziphathekayo zibe nokunyamezela ukunyanzeliswa koxinzelelo kunye nokuqina kwexesha elide le-hydrostatic.Umbhobho we-PE-RT unokuguquguquka okuhle, kwaye imodyuli yayo yokugoba yi-550 MPa, kwaye uxinzelelo lwangaphakathi oluveliswa ngokugoba luphantsi.Ngale ndlela, kuphetshwa ukuba umbhobho unokonakala kwindawo yokugoba ngenxa yoxinzelelo loxinzelelo.Xa kwakhiwa (ingakumbi ebusika), ayifuni izixhobo ezikhethekileyo okanye ukushisa ukugoba.I-Thermal conductivity ye-0. 4 W / (m·k), xa kuthelekiswa ne-PE-X ityhubhu, iphezulu kakhulu kune-PP-R 0. 22 W / (m·k) kunye ne-PB 0. 17 W / (m·k), ogqwesileyo thermal conductivity, ilungele umgangatho umbhobho ukufudumeza
Isicelo
I-QHM32F yi-resin ekhethekileyo ye-PE-RT yombhobho oveliswe yi-Qilu Branch yaseSinopec usebenzisa iteknoloji ye-Unipol.Imveliso ine bhetyebhetye elungileyo, ukusebenza kakuhle processing, uzinzo thermal kunye nokumelana noxinzelelo, nto leyo enokuhlangabezana neemfuno processing of high-speed umbhobho traction yezixhobo processing ezahlukeneyo kunye nomgangatho, kwaye ingasetyenziselwa imveliso umgangatho umbhobho zokufudumeza, aluminiyam iplastiki composite. umbhobho, umbhobho weoli, njl.
