Cov ntaub ntawv yas khoom yas tsuas yog nyob ib puag ncig ntau dua ib puas xyoo, tab sis lawv txoj kev txhim kho yog ceev heev. Qhov no vim tias cov khoom siv yas ua khoom yas muaj ntau yam zoo thiab tsis xws leej twg. Muaj ntau yam khoom siv raw khoom yas, thiab lawv cov khoom kuj tseem sib txawv. Ntawm no peb tsuas yog qhia qee qhov yam ntxwv ntawm cov khoom siv raw khoom yas.
a. Kev ruaj khov zoo. Feem ntau, cov ntaub ntawv yas muaj cov tshuaj tiv thaiv zoo thiab xeb tawm hauv cov kua qaub, alkali, thiab cov ntaub ntawv ntsev nrog qhov tsis tshua muaj siab thiab kub. Ob peb cov khoom siv yas yog tseem tiv taus cov kua qaub muaj zog thiab alkalis, yog li lawv hu ua" Yas King" ;. PTFE (polytetrafluoroethylene) cov ntaub ntawv yas khoom txawm tuaj yeem tiv taus qhov corrosion ntawm qhov muaj zog tshaj plaws" aqua regia" ;. Cov khoom yas yog qhov nyuaj rau txo qis ntawm qhov ib txwm muaj, ua cov khoom nrov ntawm cov neeg.
b. Lub teeb ci thiab zoo nkauj. Feem ntau, qhov ntom ntawm cov khoom nyoos yas yog qhov me me, kwv yees li ib nrab ntawm cov txhuas thiab ib feem tsib ntawm cov hlau. Qee cov ntaub ntawv yas, PP yas raw cov ntaub ntawv yog lub teeb dua dej, yog li cov khoom lag luam yog lub teeb pom kev zoo. Tsis tas li ntawd, feem ntau ntawm cov yas muaj qhov tshwm sim zoo nkauj thiab dav, xws li kaj, pob tshab, thiab lwm yam, thiab cov ntaub ntawv nyoos yas yog cov xim yooj yim, uas tuaj yeem ua rau cov khoom muaj ntau yam xim xim. Ua kom cov khoom nrov ntawm cov neeg.
c. Cov hluav taws xob rwb thaiv tsev zoo. Feem ntau cov plastics muaj cov hluav taws xob zoo hluav taws xob vim tias tsis muaj cov txav hluav taws xob dawb thiab cov ions hauv cov polymer. Yog li, nws tsis muaj lub peev xwm los ntsuas hluav taws xob, tab sis vim yog cov tshuaj ntxiv. Qhov no ua rau cov hluav taws xob rwb thaiv tsev ntawm cov khoom siv yas muaj qee qhov hloov pauv; cov ntaub ntawv yas feem ntau muaj cov rwb thaiv tsev txaus nyob rau ntawm qoj zaus thiab cov hluav taws xob tsawg, thiab ob peb cov ntaub ntawv yas muaj cov rwb thaiv tsev txaus txawm nyob ntawm qhov chaw siab thiab siab siab. Yog li ntawv, cov ntaub ntawv yas siv dav hauv cov khoom siv hluav taws xob, hluav taws xob, kev sib txuas lus, thiab ntsuas.
d. Superb txhua yam khoom. Cov yam ntxwv kho tshuab ntawm cov khoom siv yas yog qhov phem dua li ntawm cov hlau, tab sis cov yas muaj qhov sib dua dua li cov hlau. Yog li ntawd, lub zog muab suav rau ib pawg loj (tseem hu ua lub zog tshwj xeeb) yog ze rau lossis ntau tshaj qhov ntawm cov khoom siv hlau. Lub zog tshwj xeeb ntawm cov ntaub ntawv yas, xws li FRP, muaj ntau dua li cov hlau. Yog li, ntau cov qauv kev tsim kho tuaj yeem tsim los ntawm cov khoom siv yas.
e. Txaus hnyav khoom. Plastics muaj cov khoom zoo kawg rau cov pa roj thiab dej vapor. Yog li no, ntau lub ntim, cov khoom siv thiab cov yeeb yaj kiab ntawm cov khoom lag luam yas siv tau, uas tuaj yeem ua si zoo li cov dej thiab cov dej noo ua tau zoo.
f. Muaj nqis txheej txheem. Txhua yam khoom siv yas yog tsim los ntawm molten yas moulding tshuab. Vim tias cov ntawv tuab muaj qhov nruab nrab yaj, nws yooj yim yaj. Cov melt yog txhaj rau hauv pwm thiab cov duab tuaj yeem tsim nyob rau ib lub sijhawm luv. Complex, dimensionally ruaj khov, cov khoom lag luam zoo yas.
g. Zoo heev los tiv thaiv kev txhuam thiab coj cov khoom tiv. Cov ntaub ntawv yas feem ntau muaj qhov zoo los tiv thaiv kev txhuam, hnav-tiv taus thiab tua nws tus kheej. Lawv tuaj yeem ua haujlwm ib txwm ua haujlwm hauv dej thiab tawm xov xwm thiab tseem tuaj yeem ua haujlwm tau zoo nyob hauv ciam ciam av thiab txhuam kev txhuam. Kev ua haujlwm yog qis dua hlau. Tsuas yog cov hlau yog qhov zoo dua. Feem ntau, kev sib txhuam coefficient ntawm cov ntaub ntawv yas yog ntau qis dua li ntawm cov hlau, uas tsuas yog ib-caum rau ib-feem kaum ntawm cov hlau. Yog li, ntau cov khoom los tiv thaiv kev sib txhuam tuaj yeem ua nrog cov khoom siv yas. Thiab hnav-resistant khoom.
xyob h. Cov nyhuv ua rau poob siab. Cov ntaub ntawv yas feem ntau yog viscoelastic. Thaum lawv raug cov neeg kho tshuab kev co, viscoelastic nrog kev sib txhuam yuav tshwm sim sab hauv cov khoom siv yas, uas hloov cov khoom siv zog ua lub zog cua sov, yog li ua rau lub cev tsis muaj zog. Yog li, plastics tuaj yeem ua rau cov khoom lag luam uas tsis txaus siab thiab lub suab.
