Cov phaj polyethylene qhov no yog vim tias cov saw hlau molecular qee zaum thaiv lawv cov photocrystals, tawm hauv thaj chaw amorphous loj hauv biomolecule, polyethylene phaj tuaj yeem nqus tau ntau lub zog kinetic cuam tshuam. Raws li qhov siv, astm-D256 txoj kev siv los txiav txim siab qhov cuam tshuam ntawm cov yas compressive zog tus nqi. Raws li kev sib piv, lub zog compressive ntawm polyethylene board tuaj yeem faib ua polycarbonate, polycarbonate paub txog nws qhov kev tiv thaiv kev cuam tshuam, thiab tuaj yeem siv ua cov khoom siv roj hmab dav dav.
Qhov kev sib txhuam ntawm polyethylene phaj yog qis heev. Polyethylene board muaj kev tiv thaiv zoo dua, kev sib txhuam tsawg thiab kev ntub dej zoo. Nws yog cov khoom siv npau suav ntawm bushing, roller thiab bushing. Kev xaiv polyethylene board ua khub sib txhuam, tsis yog tsuas yog tuaj yeem txhim kho lub neej kev pabcuam puas tsuaj ntawm cov chaw, polyethylene board thiab tuaj yeem txuag cov peev txheej.
Polyethylene board muaj kev tiv thaiv tshuaj zoo. Polyethylene board muaj kev tiv thaiv tshuaj zoo dua. Ntxiv rau cov kua qaub nitric acid thiab sulfuric acid uas muaj concentrated, polyethylene board tsis yooj yim rau etched hauv cov kua alkaline lossis acidic. Nws tuaj yeem siv ua dilute hydrochloric acid ntawm 80 ℃, hauv sodium cyanide & LT; Hydrochloric acid & lt; 75% du, kuj tseem siv tau nrog dej thiab kua ntxuav. Raws li txhua tus paub, polyethylene board yooj yim heev rau o hauv aliphatic hydrocarbons lossis halogenates (tshwj xeeb tshaj yog nyob rau hauv qhov kub siab tas mus li), yog li yuav tsum tau them sai sai rau nws siv.
Txhim kho qhov kev tiv thaiv kev hnav ntawm polyethylene board. Kev tiv thaiv kev hnav siab yog ib qho ntawm cov yam ntxwv ntxias, polyethylene board hauv ntau qhov project hauv kev siv tus nqi siv tseem ceeb. Nyob rau theem no, tag nrho cov yas polyethylene board muaj kev tiv thaiv kev hnav zoo, thiab txawm tias ntau cov khoom siv hlau tsis zoo li yav dhau los. Nrog kev txhim kho ntawm qhov hnyav molecular ntawm polyethylene siab siab, qhov kev tiv thaiv kev hnav ntawm hom khoom no kuj tau txhim kho. Kev tiv thaiv kev cuam tshuam ntawm polyethylene board. Lub zog compressive ntawm polyethylene phaj yog cuam tshuam nrog nws qhov hnyav molecular. Thaum qhov hnyav molecular txheeb ze qis dua 2 lab, lub zog compressive ntawm polyethylene phaj nce nrog qhov nce ntawm qhov hnyav molecular txheeb ze, thiab tus nqi siab dua yog kwv yees li 2 lab. Ntawm lub sijhawm no, lub zog compressive cuam tshuam yuav txo qis nrog qhov nce ntawm qhov hnyav molecular txheeb ze.
