6. Cov ntsiab lus tseem ceeb ntawm txoj kev lees txais
Kev xa khoom thiab kev lees txais ntawm cov khoom siv granite yog ib kauj ruam tseem ceeb hauv kev ua haujlwm kom zoo. Raws li thawj kab ntawm kev tiv thaiv nyob rau hauv kev tsim kho qhov project zoo tswj, nws multi-dimensional xeem thiab tag nrho-txheej txheej txheem tswj tau ncaj qha cuam tshuam qhov project kev nyab xeeb, economic efficiency, thiab kev ua lag luam. Yog li ntawd, ib qho kev ruaj ntseg zoo yuav tsum tau tsim los ntawm peb qhov kev siv tshuab, kev ua raws cai, thiab kev lag luam.
Technical Level: Dual Assurance of Precision and Appearance
Lub hauv paus ntawm cov txheej txheem yog nyob rau hauv kev ua kom ntseeg tau tias cov khoom ua tau raws li cov qauv tsim kev xav tau los ntawm kev sib koom ua ke ntawm kev sib koom ua ke ntawm cov tsos thiab kev ntsuas kev ua tau zoo. Kev tswj qhov tshwm sim yuav tsum tau ua raws li tag nrho cov txheej txheem, los ntawm cov khoom ntxhib mus rau cov khoom tiav. Piv txwv li, ib qho kev sib txawv ntawm cov xim ntawm "ob qho kev xaiv rau cov khoom ntxhib, ib qho kev xaiv rau cov khoom siv phaj, thiab plaub xaiv rau lub phaj layout thiab numbering" yog siv, ua ke nrog lub teeb-dawb layout rhiav kom ua tiav ib qho kev hloov ntawm cov xim thiab cov qauv, yog li zam kev tsim kho qeeb los ntawm cov xim sib txawv. (Piv txwv li, ib qhov project tau ncua ze li ob lub lis piam vim tsis muaj kev tswj xim sib txawv.) Kev ntsuas kev ua tau zoo yog tsom rau qhov ntsuas lub cev thiab kev ua haujlwm raug. Piv txwv li, BRETON tsis siv neeg nruam sib tsoo thiab polishing tshuab yog siv los tswj flatness sib txawv mus rau <0.2mm, thaum infrared hluav taws xob choj txiav tshuab kom ntev thiab dav sib txawv rau <0.5mm. Precision engineering txawm hais tias yuav tsum muaj kev sib haum xeeb nruj ntawm ≤0.02mm / m, xav tau cov ntaub ntawv pov thawj uas siv cov cuab yeej tshwj xeeb xws li gloss meters thiab vernier calipers.
Kev Ua Raws Cai: Kev Ua Lag Luam Nkag Mus Rau Kev Ua Lag Luam rau Cov Ntawv Pov Thawj
Kev ua raws cai yog qhov tseem ceeb rau cov khoom nkag mus rau hauv kev lag luam hauv tsev thiab thoob ntiaj teb, yuav tsum tau ua raws tib lub sijhawm nrog cov qauv tsim nyog hauv tsev thiab cov ntawv pov thawj thoob ntiaj teb. Hauv tsev, kev ua raws li GB / T 18601-2024 cov kev cai rau compressive zog thiab flexural zog yog qhov tseem ceeb. Piv txwv li, rau cov tsev siab siab lossis hauv cheeb tsam txias, yuav tsum muaj kev sim ntxiv rau kev tiv thaiv te thiab cement bond zog. Hauv kev lag luam thoob ntiaj teb, daim ntawv pov thawj CE yog qhov tseem ceeb rau kev xa tawm mus rau EU thiab yuav tsum tau xeem dhau EN 1469 xeem. ISO 9001 thoob ntiaj teb kev ua haujlwm zoo, dhau los ntawm nws "peb-kev tshuaj xyuas" (kev tshuaj xyuas tus kheej, kev tshuaj ntsuam xyuas, thiab kev soj ntsuam tshwj xeeb) thiab kev tswj xyuas cov txheej txheem, ua kom muaj kev lav phib xaub zoo los ntawm cov khoom siv raw mus rau kev xa khoom tiav. Piv txwv li, Jiaxiang Xulei Pob zeb tau ua tiav kev lag luam-ua 99.8% cov khoom tsim nyog tus nqi thiab 98.6% cov neeg siv khoom txaus siab los ntawm cov kab ke no.
Economic Aspect: Ntsuas tus nqi tswj nrog cov txiaj ntsig ntev
Tus nqi nyiaj txiag ntawm txoj kev lees txais yog nyob rau hauv nws cov txiaj ntsig ob ntawm kev txo qis kev pheej hmoo luv luv thiab kev ua kom zoo rau cov nqi mus sij hawm ntev. Cov ntaub ntawv qhia tau hais tias cov nqi rov ua haujlwm vim qhov tsis txaus siab tuaj yeem suav txog 15% ntawm tag nrho cov nqi tsim khoom, thaum cov nqi kho tom ntej vim muaj teeb meem xws li pom tsis pom kev tawg thiab xim hloov tuaj yeem siab dua. Hloov pauv, kev lees txais nruj tuaj yeem txo cov nqi kho tom ntej los ntawm 30% thiab zam qhov project qeeb los ntawm cov khoom siv tsis raug. (Piv txwv li, nyob rau hauv ib qhov project, cov kab nrib pleb tshwm sim los ntawm kev tsis saib xyuas tau ua rau kev kho cov nqi ntau dua li cov peev nyiaj qub los ntawm 2 lab yuan.) Lub tuam txhab cov khoom siv pob zeb tau ua tiav 100% qhov kev lees paub los ntawm "rau-theem kev soj ntsuam zoo," uas ua rau 92.3% cov neeg siv khoom rov qab, ua kom pom qhov cuam tshuam ncaj qha ntawm kev tswj hwm kev lag luam.
Lub hauv paus ntsiab lus tseem ceeb: Cov txheej txheem lees txais yuav tsum ua raws li ISO 9001 "kev txhim kho txuas ntxiv" lub tswv yim. Lub kaw-voj "kev lees paub-kev tawm tswv yim-kev txhim kho" yog pom zoo. Cov ntaub ntawv tseem ceeb xws li kev tswj qhov sib txawv xim thiab qhov sib txawv ntawm qhov sib txawv yuav tsum tau tshuaj xyuas txhua lub hlis twg los txhim kho cov qauv kev xaiv thiab cov cuab yeej tshuaj xyuas. Lub hauv paus ua rau kev soj ntsuam yuav tsum tau ua nyob rau hauv cov ntaub ntawv rov ua haujlwm, thiab "Kev Tswj Xyuas Khoom Tsis Zoo" yuav tsum tau hloov kho. Piv txwv li, los ntawm peb lub hlis twg cov ntaub ntawv tshuaj xyuas, ib lub tuam txhab txo cov kev sib tsoo thiab polishing tus nqi txais los ntawm 3.2% mus rau 0.8%, txuag ntau tshaj 5 lab yuan nyob rau hauv cov nqi tu txhua xyoo.
Los ntawm peb qhov kev sib koom ua ke ntawm kev siv thev naus laus zis, kev ua raws cai, thiab kev lag luam, kev xa khoom ntawm cov khoom siv granite tsis yog tsuas yog kev tswj xyuas qhov zoo xwb tab sis kuj yog ib kauj ruam tseem ceeb hauv kev txhawb nqa kev lag luam tus qauv thiab txhim kho kev lag luam kev sib tw. Tsuas yog los ntawm kev koom ua ke cov txheej txheem kev lees paub rau hauv tag nrho kev lag luam saw txoj kev tswj hwm kev ua haujlwm zoo tuaj yeem ua tiav qhov kev ua haujlwm zoo, kev nkag mus rau kev lag luam, thiab cov txiaj ntsig kev lag luam.
