Cov yam ntxwv

1. Txhim kho kev tiv thaiv kev hnav. Ib qho ntawm cov yam ntxwv zoo tshaj plaws ntawm UHMW polyethylene yog nws qhov kev tiv thaiv kev hnav siab heev, uas yog qhov tseem ceeb hauv ntau daim ntawv thov engineering. Ntawm txhua yam yas, nws qhov kev tiv thaiv kev hnav yog qhov zoo tshaj plaws, thiab txawm tias qhov kev tiv thaiv kev hnav tsis tu ncua ntawm ntau cov khoom siv hlau (xws li carbon hlau, stainless hlau, tooj dag, thiab lwm yam) tsis zoo li nws. Raws li qhov hnyav molecular ntawm polyethylene nce ntxiv, cov khoom siv dhau los ua qhov tiv thaiv kev hnav ntau dua.

2. Kev tiv taus kev cuam tshuam siab heev. Lub zog cuam tshuam ntawm polyethylene hnyav molecular siab heev muaj feem cuam tshuam nrog nws qhov hnyav molecular. Thaum qhov hnyav molecular qis dua 2 lab, lub zog cuam tshuam nce ntxiv nrog qhov nce ntawm qhov hnyav molecular, thiab ncav cuag qhov siab tshaj plaws ntawm kwv yees li 2 lab. Tom qab qhov siab tshaj plaws, lub zog cuam tshuam nce ntxiv nrog qhov hnyav molecular. Qhov no yog vim tias cov saw molecular tsis zoo thiab cuam tshuam nws cov photocrystallization, yog li muaj thaj chaw amorphous loj hauv macromolecule, uas tuaj yeem nqus tau lub zog cuam tshuam loj.

3. Kev sib txhuam tsawg. UHMWPE tsis yooj yim hnav, muaj kev sib txhuam tsawg thiab kev ua kom lubrication zoo, thiab yog cov khoom siv zoo tagnrho rau kev tuav cov bushings, sliders thiab linings.
Kev siv cov polyethylene hnyav molecular siab heev ua qhov sib txhuam ntawm cov khoom siv tsis tsuas yog txhim kho lub neej hnav-resistant, tab sis kuj txuag hluav taws xob.

4. Kev tiv thaiv tshuaj lom neeg zoo. Polyethylene hnyav molecular siab heev muaj kev tiv thaiv tshuaj lom neeg zoo. Tsuas yog cov kua qaub nitric acid thiab cov kua qaub sulfuric uas muaj concentrated xwb, nws yuav tsis raug xeb hauv txhua yam lye thiab cov kua qaub, thiab tuaj yeem siv rau hauv cov kua qaub hydrochloric uas muaj concentrated ntawm qhov kub (80 ° C, Nws kuj ruaj khov hauv<20% nitric acid,<75% sulfuric acid, thiab nws kuj ruaj khov hauv dej, kua ntxuav.)
Txawm li cas los xij, polyethylene uas muaj molecular hnyav heev yooj yim o hauv cov tshuaj aromatic lossis halogenated (tshwj xeeb tshaj yog nyob rau hauv qhov kub siab dua), yog li yuav tsum tau them sai sai thaum lub sijhawm thov.

5. Kev nqus dej tsawg heev. UHMWPE muaj qhov nqus dej tsawg heev, nws yuav luag tsis nqus tau, tsis o hauv dej, thiab tsis nqus tau ntau dua li nylon.

6. Cov khoom siv thermal. Raws li txoj kev ntawm ASTM (load 4.6kg/cm2), qhov kub ntawm qhov kub thiab txias yog 85 ℃. Hauv qab qhov me me, qhov kub ntawm kev pabcuam tuaj yeem ncav cuag 90 ℃. Hauv cov xwm txheej tshwj xeeb, nws raug tso cai siv ntawm qhov kub siab dua. Polyethylene hnyav molecular siab yog cov khoom siv uas muaj kev tawv zoo heev, yog li nws qhov kev tiv thaiv qis kuj zoo heev, thiab nws tseem muaj qee qib ntawm kev ductility ntawm qhov kub qis ntawm -269 ° C, thiab tsis muaj cim ntawm embrittlement.

7. Cov khoom siv hluav taws xob. UHMWPE muaj cov khoom siv hluav taws xob zoo heev hauv qhov kub thiab txias dav, nws qhov tsis kam yog 10-18CM, nws lub zog tawg yog 50KV / hli, thiab nws qhov dielectric tas mus li yog 2.3. Hauv qhov kub thiab txias thiab zaus dav, nws cov khoom siv hluav taws xob hloov pauv me ntsis. Hauv qhov kub thiab txias uas tiv taus cua sov, nws tsim nyog siv ua cov ntaub ntawv tsim kho hauv kev tsim hluav taws xob thiab cov ntaub ntawv hauv cov ntawv zeb.

8. Cov polyethylene uas tsis muaj tshuaj lom thiab muaj molecular weight siab heev, tsis muaj saj, tsis muaj tshuaj lom, tsis muaj ntxhiab, tsis xeb, thiab muaj kev ncig thiab kev hloov pauv ntawm lub cev. Lub Koom Haum Saib Xyuas Khoom Noj thiab Tshuaj ntawm Tebchaws Meskas (FDA) thiab Lub Tsev Haujlwm Saib Xyuas Kev Ua Liaj Ua Teb ntawm Tebchaws Meskas (USDA) tso cai rau nws siv rau hauv kev sib cuag nrog zaub mov thiab tshuaj.
Nws cov yam ntxwv, tshwj xeeb tshaj yog kev hnav tsis kam, kev cuam tshuam tsis kam, thiab cov khoom siv lubricating tus kheej, yog qhov zoo tshaj plaws ntawm cov yas engineering.
