Putty riam yog ua raws li ntau yam kev ntsuas los xyuas kom meej lawv qhov zoo, kev ua tau zoo, thiab kev nyab xeeb.
Ib qho ntawm qhov tseem ceeb yog qhov kev sim hardness. Lub hardness ntawm cov hniav yog ntsuas siv txoj kev zoo li Rockwell hardness test. Qhov no txiav txim siab yog tias cov hniav muaj qhov zoo ntawm hardness kom kis tau zoo thiab txhuam cov putty yam tsis muaj nkig lossis muag heev. Ib rab riam uas tawv dhau yuav tawg lossis nti thaum siv, thaum ib qho uas mos heev yuav tsis muaj peev xwm tuav cov ntaub ntawv tawv. Qhov zoo tshaj plaws hardness ntau ua kom durability thiab zoo functionality.
Ntug sharpness thiab tuav kuj tseem ceeb heev. Cov hniav ntawm ntug yuav tsum tau sim rau nws qhov pib sharpness thiab zoo npaum li cas nws khaws qhov sharpness tom qab siv dua. Qhov no tuaj yeem cuam tshuam nrog kev txiav cov qauv putty qauv lossis lwm yam ntaub ntawv thiab ntsuas qhov zoo ntawm kev txiav. Ib tug ntse thiab ntev-ntev ntug tso cai rau meej daim ntawv thov thiab tshem tawm ntawm putty, uas ua rau ib tug smoother tiav.
Kov lub zog thiab kev nplij siab yog ntsuas. Tus kov yuav tsum muaj peev xwm tiv taus lub zog siv thaum lub sijhawm siv ib txwm tsis tawg lossis xoob. Kev ntsuam xyuas yuav suav nrog kev siv qee qhov tshwj xeeb ntawm lub zog rau tus kov los xyuas nws qhov kev tiv thaiv. Tsis tas li ntawd, lub ergonomics ntawm tus kov raug txiav txim siab, xws li nws tuav kev nplij siab thiab nws haum zoo li cas hauv tes. Ib qho yooj yim kov txo cov neeg siv qaug zog thiab txhim kho kev siv tag nrho.
Corrosion kuj yog lwm qhov kev sim tseem ceeb, tshwj xeeb tshaj yog rau cov riam uas ua los ntawm cov hlau. Cov riam yog raug rau ntau yam corrosive agents thiab ib puag ncig los ntsuas nws lub peev xwm los tiv thaiv xeb thiab deterioration. Qhov no yog qhov tseem ceeb vim tias cov riam tuaj yeem nkag mus rau hauv cov dej noo lossis tshuaj lom neeg thaum siv.
Thaum kawg, qhov tseeb qhov tseeb yog qhov tseeb los xyuas kom meej tias cov riam putty ua tau raws li qhov xav tau ntawm qhov loj thiab cov duab. Qhov no suav nrog kev txheeb xyuas qhov ntev, qhov dav, thiab tuab ntawm cov hniav thiab tuav, nrog rau tag nrho cov symmetry thiab ncaj. Los ntawm kev ua raws li cov qauv ntsuas no, cov tuam txhab tsim khoom tuaj yeem tsim cov riam zoo tshaj plaws uas ua tau raws li qhov kev cia siab ntawm ob tus neeg ua lag luam thiab cov neeg nyiam DIY, kom ntseeg tau tias kev ua tau zoo thiab kev ua haujlwm ntev.
