Lub cev kev ua tau zoo yuav tsum muaj:
Yuav tsum muaj zog: lub zog ntawm steel fibers yog qhov taw qhia tseem ceeb ntawm lawv cov khoom zoo. Hom kev txhawb zog muaj xws li muaj lub zog tsis muaj zog (LS), nruab nrab lub zog (MS) thiab lub zog siab (HS). Thaum ua cov ntawv xeem ua kom muaj kev ua tau zoo ntawm lub cev, cov forsion, torsion thiab cuam tshuam nrog cov qauv uas muaj feem xyuam uas lawv yuav tsum muaj cov khoom siv muaj zog.
Corrosion Kuj: Steel Fibers yuav corroded los ntawm cov tshuaj thiab noo noo nyob hauv ib puag ncig thaum lub sijhawm siv, yog li corrosion kuj tseem yog qhov tseem ceeb. Cov khoom siv hlau txuas yuav tsum tau tshuaj ntsuam ntsev rau cov kua qaub thiab cov kua qaub thiab alkali, los soj ntsuam lawv cov xeb ntawd.
Cov duab puab thiab qhov loj me: cov duab thiab qhov loj me ntawm cov ncej hlau muaj qhov tseem ceeb ntawm lawv cov kev tawg thiab kev cuam tshuam rau hauv cov pob zeb ua. Cov xov hlau sib xyaw hlau yog cov hlau xaim lossis cov hlau xaim hlau los yog hlau xaim nrog lub cheeb ntawm} mm, ib qho ntev ntawm {mm, thiab a Txoj kab uas hla ntawm 0. 2-0. 6 hli.
Tshuaj lom neeg cov tshuaj lom neeg yuav tsum tau ua:
Cov ntsiab lus tseem ceeb: cov tshuaj lom neeg cov tshuaj lom neeg ntawm cov hlau fiber ntau muaj qhov cuam tshuam tseem ceeb ntawm nws lub cev lub cev thiab corrosion tsis kam. Cov ntsiab lus ntau ntawm ntau yam tseem ceeb (xws li cov carbon, leej faj, phosphorus, thiab lwm yam) ua kom meej meej tias cov fiber ntau cov tshuaj lom neeg cov tshuaj lom neeg.
Impurity cov ntsiab lus: kev hloov pauv hloov rau lwm lub ntsiab lus lossis txuas ntxiv dua li cov ntsiab lus tseem ceeb, uas yuav cuam tshuam kev ua yeeb yam ntawm cov hlau fiber ntau. Cov txheej txheem hluav taws xob steel yuav tsum tau kuaj rau cov ntsiab lus impurity, thiab cov qauv sib sau yuav tsum tau tsim kom meej rau cov ntsiab lus pub tau muaj ntau yam tsis txaus ntseeg.
Cov Txheej Txheem Ntau Lawm Yuav Tsum:
Cov khoom siv raw: Muaj cov ntaub ntawv raw zoo yuav tsum tau xaiv rau kev tsim khoom, thiab cov ntaub ntawv raw yuav tsum muaj qee lub zog thiab corrosion tsis kam.
Kev tsim cov txheej txheem ntau lawm: thaum lub sijhawm tsim khoom, txhua qhov txuas yuav tsum tau nruj me ntsis tswj hwm kom ntseeg tau tias cov khoom lag luam. Xws li cov khoom siv raw-precreatment, txiav thiab lwm txoj kev txuas yuav tsum tau nruj kev tswj hwm, thiab ua kom muaj kev tswj hwm cov kev tswj hwm zoo.
Cov qauv kuaj thiab khoom siv: Qhov kev tshuaj xyuas zoo ntawm cov hlau fiber ntau yog qhov txuas tseem ceeb kom ntseeg tau tias nws tau ua raws li cov kev tseev kom ntseeg tau tias nws thiab khoom siv tsim nyog yuav tsum siv rau kev sim.
Lwm yam kev xav tau:
Cov ntsiab lus los ntawm cov hlau yuav tsum tsis txhob muaj roj, coated nrog cov tshuaj tsis zoo lossis cov impurities uas cuam tshuam rau cov hlau fiber thiab qhob.
Ntev sib txawv: Qhov ntev sib txawv ntawm cov hlau fiber yuav tsum tsis pub tshaj 10% ntawm tus qauv ntev, thiab tsawg kawg 10 tus neeg yuav tsum tau kuaj xyuas txhua pob.
Txoj kab uas hla los yog sib npaug ntawm cov taub uas tsim nyog: txoj kab uas cov taub uas tsim nyog yuav tsum tsis txhob siv tau 90%, thiab qhov hnyav txheej txheem yuav siv tau rau kev kuaj xyuas. 100 tus ntoo yuav tsum tau raug kuaj nyob rau hauv txhua pob, luj nrog kev sib npaug, thiab ntsuas qhov ntev ntev nrog tus caliper. Tus nqi sib npaug hauv nruab nrab muaj nqis yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua.
