Txiav lub logTej zaum yuav tshwm sim yooj yim, tab sis lawv qhov kev ua tau zoo nyob ntawm kev sib xyaw ntawm cov nplej abrasive, cov khoom sib txuas, cov khoom siv ntxiv, thiab lwm yam khoom xyaw.
Abrasive Grains
Abrasive grains yog lub luag hauj lwm rau qhov tseeb txiav txiav. Aluminium oxide yog dav siv los txiav carbon steel thiab lwm yam hlau ferrous. Zirconia-alumina thiab ceramic-raws li abrasives raug xaiv thaum txiav nrawm dua, muaj zog dua, lossis lub log ntev dua.
Silicon carbide yog ib qho ntse, tawv abrasive feem ntau siv rau cov ntaub ntawv xws li pob zeb, masonry, cam khwb cia hlau, thiab tej yam tsis yog -ferrous hlau. Qhov loj grit tsim nyog yuav tsum tau xaiv ib txwm raws li lub workpiece thiab daim ntawv thov.
Resin Bond
Feem ntau cov kev txiav cov log siv nrog lub kaum sab xis yog cov cob- khi. Cov khoom sib txuas tuav cov nplej abrasive ua ke, tso cai rau lub log kom nws cov duab thaum ua haujlwm.
Daim ntawv cog lus yuav tsum ua kom muaj qhov sib npaug ntawm lub zog thiab tswj kev hnav. Yog tias lub log nyuaj dhau, kev txiav ceev yuav txo qis; yog tias nws hnav sai heev, cov khoom lag luam yuav luv luv.
Fiberglass Reinforcement
Fiberglass mesh feem ntau yog ntxiv rau cov log kom lawv lub zog thiab txhim kho lawv cov kev tiv thaiv rau kev ua haujlwm. Tus naj npawb thiab qhov chaw ntawm cov txheej txheem kev txhawb zog sib txawv nyob ntawm seb lub log hom, thickness, thiab kev npaj siv.
Additives thiab Fillers
Lwm cov ntaub ntawv yuav raug ntxiv los txhim kho kev ua haujlwm, tswj cov cua sov, ua kom lub zog ntawm lub log, thiab txhim kho kev tsim khoom sib xws. Daim ntawv ua tiav yuav tsum tau ua kom haum rau cov khoom siv lub hom phiaj, lub tshuab ceev, thiab cov khoom xav tau qhov chaw.
Vim li cas xaiv cov khoom tseem ceeb
Ob lub log ntawm tib qhov loj tuaj yeem ua qhov sib txawv vim muaj kev hloov pauv ntawm cov nplej zoo, kev tsim, cov khoom siv ntxiv, thiab cov txheej txheem tsim khoom. Yog li ntawd, thaum xaiv lub log txiav, cov neeg yuav khoom yuav tsum xav txog yam tshaj li qhov loj thiab tus nqi - xws li hom workpiece, daim ntawv thov scenario, qhov siab tshaj plaws kev khiav hauj lwm ceev, thiab xav tau kev txiav.
