Iipropati ezisisiseko ze-Ultra-high bound Polythylene (Uhmpe)

July 07, 2024

I-Ultra-gooneund Polythylene (UhMWP) ngokubanzi ibhekisa kwi-polyethylene ngesixokelelwane se-100 × 104 okanye ngaphezulu, kwaye luhlobo olutsha lweplasitiki yobunjineli. Ukuxinana kwe-UhMWP ene-avareji yemolekyuli yemolekyuli ye-200 × 104 yi-0.935g / cm3, engaphantsi kwe-50% engaphezulu kwe-PTFE, kwaye ngaphezulu kwe-30% esezantsi kune Leyo yeParaformaldehyde, ngoko ke iimveliso zayo zibonakaliswa ubunzima bokukhanya. I-UhMWPE ineentlobo ngeentlobo zeepropathi ezibalaseleyo, iipropathi zomzimba, iipropathi zekhemikhali, ukunyangeka kakhulu, ukunganyangeki, ukunganyangeki, ukunganyangeki, akukho lula ukubambelela kwizinto zangaphandle, ucoceko kwaye Ukungakhathali, ukuphinda kusetyenziswe kwakhona kunye nokuxhathisa kobushushu obungaphantsi, njl. Iintsilelo zayo kukungaxhathisa ubushushu obuthile, ubunzima obuphantsi, amandla amanye amanxuwa, iipropathi ezihlwempuzekileyo.

(1) Ukunganyangeki kwempembelelo

Amandla empembelelo ye-Uhmwpe phakathi kweyona nto ibalulekileyo kwitrastiki yobutyebi bonke. I-UhMWPE inokugcina ukunganyangeki kwefuthe elihle ngakumbi nangaphantsi kobushushu obuphantsi, kwaye nakwiitrogen (-196 ℃), i-Uhmwpe nayo inefuthe elihle, oluyinto enye abangenayo ezinye iiplastiki. Amandla ayo aqala ukwanda ngokunyuka kwesixa semolekyuli yemolekyuli, isixa semolekyuli esiyi-150 × 104 okanye ukuze afike kwixabiso layo eliphezulu, emva koko wehla kancinci. Amandla empembelelo ye-Uhmwpe malunga namaxesha ama-2 njenge-polycarbonate, i-5 ka-ABS izihlandlo ezi-5, i-PA, iParamaddehyde kunye ne-PBT ngaphezulu kwamaxesha ali-10.

(2) Ukunganyangeki kwe-abrasion

Ukuchasana kuka-Abrashion ye-Uhmwpe icobe uluhlu lweeplasitiki, izihlandlo ezininzi kunelo yensimbi yekharbon kunye nobhedu, kwaye ukuxhathisa i-abrasion kunokuphuculwa ngakumbi ngokunyuka kwesixa semolekyuli. Umzobo 1-1 ubonakalisa uthelekiso lokunganyangeki phakathi kwe-UHMWP kunye nezinye izinto. Iimeko zovavanyo zezi zilandelayo: Udaka lwenziwe ngamalungu ama-2 amaninzi kunye neenxalenye ezintathu zesanti; Isantya esijikelezayo sesiqwenga sovavanyo siyi-900r / imiz; Ixesha lokubaleka yi-7h.

(3) ukuzithoba

I-Uhmwpe inezinto zokuzimela ngokugqwesileyo kunye nento ephantsi enamandla enokuthelekiswa ne-ptfe. Itheyibhile 1-2 LUTHETHA UTSHINTSHO LOMNQOPHISO WOKUGQIBELA WOKUGQIBELA WAHMWP kunye nezinye iiplasitini zobunjineli. Ingabonwa ukuba imeko ye-fancy ye-UhMwpe phantsi kolungiso lwamanzi yi-16 ye-PA66 ye-PA66 kunye ne-POM, kwaye phantsi kweemeko ezingekho phantsi kwe-ptfere kuphela kwiPlastiki. Xa isebenza ekutyibilikeni okanye ijikeleze ifom, inomsebenzi ongcono wokutsiba kunentsimbi kunye nobhedu ngeoyile ye-oyile. Ngapha koko, ixabiso le-Uhmufpe liphantsi, kunjalo kwicandelo le-phabology, lithathwa njengezixhobo ezixineneyo ngomyinge wokusebenza kakuhle kakhulu.

Thelekisa into eguqukayo phakathi kwe-UhMWP kunye nezinye iiplasitini zobunjineli

Isixhobo	Ingenziwe	Amanzi ancitshisiweyo	I-oyile ihlanjululwe
Uhmwpe	I-0.10 ~ 0.22	I-0.05 ~ 0.10	I-0.05 ~ 0.08
Ptfe	I-0.04 ~ 0.25	I-0.04 ~ 0.08	I-0.04 ~ 0.05

I-POM	I-0.15 ~ 0.35	I-0.10 ~ 0.20	I-0.05 ~ 0.10

(4) Amandla e-thensle

Ukuveliswa kwesivuno se-Uhmwpe kunxulumene nobunzima bemolekyuli kunye nokuxinana kwesixa semolekyuli kunye nokuxinana kwemolamente, amandla amnandi ancipha; Nangona kunjalo, xa i-vernity yi-0.94G / cm3 okanye ubunzima bemolekyuli yemolekyuli ingaphezulu kwe-150 × 104, ukutshintsha kwamandla okuvelisa amanqwanqwa kuyancipha, kwaye ngokusisiseko kuya kuba lixabiso elisigxina. I-thansle yokuqhekeza amandla enxulumene kuphela nesisindo semolekyuli, kwaye ifuthe lokuxinana kulo lingakhathalelwanga. Ngokuchasene ne-consile yesivuno sokuzala, kunye nokunyuka kwesixa semolekyuli yemolekyuli, amandla ophule amanxuwa akhule ngokufanelekileyo.

3. Iipropathi zombane

Ngokufanayo ne-polyethylene eqhelekileyo, i-molecular ye-Uhmwpe idityaniswe kuphela yikharbon kunye ne-hydrogen, iipropathi zombane ze-Uhmwpe zizimele ubuninzi be-molecular molecular isihlobo semolekyuli. Ukunganyange kwayo kukuphakama kwi-1016 ~ 1018º-CM, kunye ne-Tacleric Angle Tangent yi (2 ~ 3) × 10. 4.

4. Iipropathi ze-thermal

Ukumelana nobushushu be-UhMWPE akuphakamisi, iqondo lobushushu lingaphantsi kwe-100 ℃. Nangona kunjalo, ngenxa ye-molecular ye-molecular yayo enkulu, ngoko ke ubushushu obunobushushu obugqwethekileyo kunye nendawo yokuthambisa iVictat iphakamile kune-HDPE eqhelekileyo, indawo yokunyibilika (136 ℃) ingafaniyo neyo ye-HDPE eqhelekileyo, Nangona kunjalo, i-Uhmwpe inobushushu obunobushushu obuphantsi kakhulu, eyona ilungileyo phakathi kwazo zonke iiplasitiki, iqondo lobushushu leBrittle lingaphantsi -70 ℃, nokuba i-helium yobushushu be-helium (-3 ℃, kunye nobushushu beqondo lobushushu i-helium (-4 ℃) ingezantsi -70 ℃, kunye neqondo lobushushu leqondo lokushisa i-helium lingaphantsi -70 ℃. Iqondo lobushushu leBrittlet lingaphantsi -70 ° C, kwaye nakwiiDartures Heartrerations (-269 ° C) isenamandla amachaphaza amachaphaza kunye nokuxhathisa i-arasion. Nokuba kubushushu obunqabileyo (-269 ℃), kusenawo amandla athile empembelelo kunye nokuxhathisa i-arasion. Uluhlu lwamaqondo obushushu olusebenzayo luvela ku-265 ukuya kwi-100 ℃, kwaye lisenokugcina ubuchule obulungileyo xa ubushushu busezantsi kwinxalenye yobushushu obuphantsi, i-Pipelines, kunye neqondo lokuhlala eliphantsi kakhulu iimeko ezinjengoMzi-mveliso wenyukliya.

5. Ukuxhathisa kwemichiza

I-Uhmwpe inomchasi ogqwesileyo. I-Diethane, i-Ethylene Glycol, iPetroli, Hexane, Carbowane, i-Idbon Ssoby, I-Ebethane Ssoby, i-ETYLY TOOBS, MEYLYL TOOLDS, inkangeleko Imbonakalo ye-phenomenaus phenomena, ukwenziwa kweentlobo ezahlukeneyo zabantu ezingafaniyo. Oku kungenxa yokuba ubunzima be-iltra-goothyley i-polythylene ayinalo neqela elisebenzayo kwisakhiwo semolekyuli, kwaye phantse akukho nto ibhaliweyo kunye ne-cust kunye ne-crystallies ephezulu. Nangona kunjalo, ayizinzanga kwi-icid egxile kwi-acid, i-witric acid ye-witric acid, i-hidrocarbons ye-hidrocarbons enee-hydrocarble kunye nezinye izinyibilikisi, kwaye isantya se-Oxidation sonyuka kunye nesantya se-oxidation sonyuka kunye nesantya se-oxidation sanyuka kunye nesantya se-oxidation sonyukayo.

6. Ukuthathwa kwamanzi

Inqanaba lokufumana amanzi le-Uhmwpe lelona lincinci leeplanga zobunjineli (jonga kwiTheyibhile 1-3), nto leyo ngenxa yokuba i-molecular thein ye-Uhmwpe iqulathe i-carbon kunye nezinto ze-hydrogen kuphela, kwaye akukho qela lepoler kwimolekyuli, Ke inqanaba lokufumana amanzi liphantsi kakhulu. Ke ngoko, iimveliso azizukutshintsha ngokobukhulu ngenxa yokufunxa kwamanzi nakwindawo enomswakama, kwaye kwangaxeshanye, ayiyi kuchaphazela iipropathi zoomatshini beemveliso, ezinje ngokuchasene ne-abrasion, kwaye izinto ezingalunganga azidingi Ukomiswa ngaphambi kokubumba kunye nokulungisa.
