Lub hardness ntawm ib tug putty riam yog ib qho tseem ceeb yam ntxwv uas cuam tshuam nws functionality thiab ntev.
Putty riam feem ntau yog tsim los ntawm cov ntaub ntawv xws li carbon steel thiab stainless hlau. Carbon steel putty riam feem ntau muaj qhov nyuaj ntawm HRC 40 - 50. Qhov no hardness theem endows lub riam nrog rau qhov tsim nyog rigidity rau scrape tawm qub putty los yog kis tshiab putty tusyees. Cov pa roj carbon steel yog hardened los ntawm kev kho cua sov, uas hloov nws cov qauv sab hauv los txhim kho nws lub zog thiab hardness. Qhov no ua rau cov riam phom tuaj yeem tiv taus lub zog tawm thaum siv yam tsis muaj dabtsi yog khoov lossis warping yooj yim.
Rau stainless hlau putty riam, qhov nyuaj hardness yog nyob ib ncig ntawm HRC 30 - 40. Txawm hais tias lawv tsis nyuaj li cov pa roj carbon steel, lawv muaj qhov zoo ntawm kev tiv thaiv corrosion zoo dua. Qhov no ua rau lawv tsim nyog siv rau hauv qhov chaw ntub dej lossis qhov chaw ntub dej uas muaj kev pheej hmoo ntawm xeb tsim. Qhov qis qis kuj tseem muab qee qhov kev hloov pauv yooj yim, uas tuaj yeem muaj txiaj ntsig zoo thaum ua haujlwm ntawm qhov tsis sib xws lossis thaum yuav tsum tau ua kom muaj kev sib haum xeeb kom tsis txhob ua rau cov khoom siv hauv qab.
Yog hais tias lub riam phom hnyav dhau lawm, nws yuav ua rau nkig thiab tawg thaum raug kev puas tsuaj los yog quab yuam ntau dhau, tshwj xeeb tshaj yog thaum xav tau kev ua haujlwm ntau dua. Ntawm qhov tod tes, yog tias nws yog mos heev, nws yuav tsis tuaj yeem tshem tawm los yog siv cov putty, ua rau qhov ua tiav tsawg dua.
Hauv kev xaus, kev paub txog qhov nyuaj ntawm cov riam phom yog qhov tseem ceeb rau cov neeg siv xaiv cov cuab yeej tsim nyog rau lawv cov haujlwm tshwj xeeb. Txawm hais tias nws yog ib txoj haujlwm DIY me me los yog kev pleev xim rau kev ua haujlwm thiab kho kom zoo nkauj, txoj cai hardness ntawm putty riam tuaj yeem ua kom zoo thiab siv tau zoo thiab tshem tawm cov putty, uas ua rau muaj kev ua tiav zoo.
