Iipropati zeMichiza kunye nezomzimba I-PC / i-PBT ineempawu ezidibeneyo zombini i-PC kunye ne-PBT, njengokuqina okuphezulu kunye nokuzinza kwejometri ye-PC kunye nokuzinza kweekhemikhali, ukuzinza kwe-thermal kunye ne-lubrication properties ze-PBT.

3.PE-HD

Izicelo eziqhelekileyo: izitya zefriji, izitya zokugcina, ikhitshi yasekhaya, izivalo zokutywina, njl.

Iimeko zenkqubo yokubumba isitofu.
Ukomisa: Akukho mfuneko yokoma ukuba igcinwe kakuhle.
Ubushushu obunyibilikayo: 220 ukuya kuma-260°C.Kwiimathiriyeli ezineemolekyuli ezinkulu, ubushushu obucetyiswayo bokunyibilika buphakathi kwama-200 kunye nama-250°C.
Ubushushu bokungunda: 50-95°C.Ubushushu obuphezulu bokungunda kufuneka busetyenziswe kubunzima bodonga obungaphantsi kwe-6mm kunye nobushushu obusezantsi bokungunda kubunzima bodonga obungaphezulu kwe-6mm.Ubushushu bokupholisa bamacandelo eplastiki kufuneka bufane ukuze kuncitshiswe umahluko wokushwabana.Ngelona xesha lilungileyo lomjikelo, idiameter yomngxuma wokupholisa kufuneka ingabi ngaphantsi kwe-8mm kwaye umgama osuka kwindawo yokungunda kufuneka ube ngaphakathi kwe-1.3d (apho u-“d” bububanzi bomgodi wokupholisa).
Uxinzelelo lwe-injection: 700 ukuya kwi-1050 bar.
Isantya sokutofa: Inaliti yesantya esiphezulu iyacetyiswa.Iimbaleki kunye namasango: Idayamitha yembaleki kufuneka ibe phakathi kwe-4 kunye ne-7.5 mm kwaye ubude bembaleki kufuneka bube mfutshane kangangoko.Iindidi ezahlukeneyo zamasango zingasetyenziswa kwaye ubude besango akufanele budlule i-0.75mm.ingakumbi ilungele ukusebenzisa iimolds zembaleki eshushu.
Iipropati zeMichiza kunye nezomzimba: I-crystallinity ephezulu ye-PE-HD ibangela ukuxinana okuphezulu, amandla okuqina, ubushushu obuphezulu beqondo lokushisa, i-viscosity kunye nokuzinza kweekhemikhali.I-PE-HD inobuxhakaxhaka obuphezulu bokuchasana ne-PE-LD.I-PE-HD inamandla empembelelo ephantsi.Iipropati ze-PH-HD zilawulwa ikakhulu ngokuxinwa kunye nokusabalalisa ubunzima be-molecular.Ukuhanjiswa kobunzima bemolekyuli ye-PE-HD efanelekileyo yokubumba inaliti incinci kakhulu.Ubuninzi be-0.91-0.925g / cm3, siyibiza ngokuba luhlobo lokuqala lwe-PE-HD;ngenxa yobuninzi be-0.926-0.94g / cm3, kuthiwa luhlobo lwesibini lwe-PE-HD;ngenxa yobuninzi be-0.94-0.965g / cm3, ibizwa ngokuba luhlobo lwesithathu lwe-PE-HD.-Izinto eziphathekayo zineempawu ezihamba kakuhle, kunye ne-MFR phakathi kwe-0.1 kunye ne-28. Ukuphakama kwesisindo se-molecular, ihlwempu kakhulu iimpawu zokuhamba kwe-PH-LD, kodwa ngamandla anamandla empembelelo.PE-LD yimpahla ye-semi-crystalline ene-shrinkage ephezulu. emva kokubumba, phakathi kwe-1.5% kunye ne-4%.I-PE-HD inyibilika ngokulula kwizinyibilikisi ze-hydrocarbon kumaqondo obushushu angaphezu kwe-60C, kodwa ukuchasana kwayo nokupheliswa kubhetele kunoko kwe-PE-LD.

4.PE-LD
Ukomisa: ngokubanzi akufuneki
Ubushushu obunyibilikayo: 180℃ 280℃
Ubushushu bomngundo: 20℃ 40℃ Ukuze kuphunyezwe ukupholisa okufanayo kunye nokuphelisa ukufudumeza okunoqoqosho ngakumbi, kucetyiswa ukuba isithuba sokupholisa somgodi wokupholisa kufuneka sibe yi-8mm ubuncinane kwaye umgama ukusuka kumngxuma wokupholisa ukuya kumphezulu wokungunda kufuneka ungagqithi amaxesha ayi-1.5 Idayamitha yomngxuma wokupholisa.
Uxinzelelo lwe-injection: ukuya kuthi ga kwi-1500 bar.
Ukubamba uxinzelelo: ukuya kuthi ga kwi-750 bar.
Isantya sokutofa: Isantya sokutofa ngokukhawuleza siyacetyiswa.
Abagijimi kunye namasango: Iindidi ezahlukeneyo zeembaleki kunye namasango anokusetyenziswa i-PE ifanelekile ngokukodwa ukusetyenziswa kunye nokubumba okutshisayo.
Iimpawu zeMichiza kunye nezomzimba: Ubuninzi bezinto ze-PE-LD zokusetyenziswa kwezorhwebo yi-0.91 ukuya kwi-0.94 g / cm3.PE-LD ingena kwi-gas kunye nomphunga wamanzi.I-coefficient ephezulu yokwandiswa kwe-thermal ye-PE-LD ayifanelekanga ukulungiselela iimveliso ukusetyenziswa ixesha elide.Ukuba ubuninzi be-PE-LD buphakathi kwe-0.91 kunye ne-0.925g / cm3, ngoko izinga layo lokunciphisa liphakathi kwe-2% kunye ne-5%;ukuba ubuninzi buphakathi kwe-0.926 kunye ne-0.94g / cm3, ngoko izinga layo lokunciphisa liphakathi kwe-1.5% kunye ne-4%.Ukuncipha kwangoku kwangoku kuxhomekeke kwiiparamitha zenkqubo yokutofa.I-PE-LD iyaxhathisa kwizinyibilikisi ezininzi kwiqondo lobushushu begumbi, kodwa izinyibilikisi zehydrocarbon ezinevumba elimnandi kunye neklorinithi zinokubangela ukuba zidumbe.Ngokufana ne-PE-HD, i-PE-LD ichaphazeleka kuxinzelelo lokusingqongileyo.
