Thaum nws tuaj txog ntawm ob qho chaw ntawm lub tshuab tsis zoo, tsis muaj kev ntseeg txog lub cev thiab cov khoom siv tshuaj. Tom qab ntawd peb yuav tuaj yeem nkag siab yooj yim ntawm ob lub zog ntawm lub ntsej muag hnub no, thiab cov phooj ywg tuaj koom nrog peb lub tuam txhab thiab lub hoobkas tuaj xyuas, tos ntsoov rau qhov koj tuaj xyuas!
Cov khoom hauv lub cev :
Qhov kub ua kom tsis zoo ntawm lub tshuab tsis zoo yog tsis siab. Txawm hais tias nws lub iav hloov kub kub li 104 ° C, qhov siab tshaj plaws kev siv ntsuas kub yog li ntawm 65 ° C thiab 95 ° C nyob ntawm qhov kev ua haujlwm. Lub tshav kub distortion yog li 96 ° C (1.18 MPa). ), Vicat softening taw tes txog 113 ° C. Lub thermal stability ntawm cov xim pleev xim yog nruab nrab, zoo dua polyvinyl chloride thiab polyoxymethylene, tiam sis tsawg dua polyolefin thiab polystyrene, thermal decomposition qhov kub yog me ntsis siab tshaj 270 ° C, thiab nws cov dej kub yog txog 160 ° C, yog li ntawd tseem muaj ntau txoj dej kub ntau.
Cov khoom siv tshuaj :
Plexiglass tuaj yeem tiv taus cov hmoov uas tsis muaj zog hauv cov organic acids, tab sis concentrated inorganic acids yuav erode nws thiab yuav ua tau resistant rau alkalis, tab sis sov sodium hydroxide thiab potassium hydroxide tau etch nws, thiab tau tuaj ntsev thiab roj. Nws yog resistant to aliphatic hydrocarbons, insoluble hauv dej, methanol, glycerin, thiab lwm yam., Tab sis absorbs alcohols thiab swells, thiab ua rau tawg nthe, uas yog tsis resistant rau ketones, chlorinated hydrocarbons thiab cov ntxhuav hydrocarbons. Nws qhov teeb meem ntawm qhov teeb meem yog 18.8 (J / CM3) 1/2, soluble nyob rau hauv ntau cov tshuaj hydrocarbons thiab cov ntxhuav hydrocarbons, xws li dichloroethane, trichlorethylene, chloroform, toluene, thiab lwm yam., Vinyl acetate thiab acetone kuj tseem ua kom tiav. Plexiglass tau ua haujlwm zoo rau cov roj ntsha xws li cov roj ntsha thiab cov tshuaj lom dioxide.
