Kev daws qhov teeb meem sib xws ntawm Synthetic Pob Zeb Diamond: Kev Tswj Xyuas Zoo Thiab Kev Pabcuam Los Ntawm Tuam Tshoj Super Tech
Jun 17, 2026| 
Hauv kev tsim khoom ntawmresin/hlau bonding abrasive log, pob zeb diamond pom hniav, thiab geological laum khoom, qhov sib xws ntawm cov pob zeb hluavtaws ncaj qha cuam tshuam cov txiaj ntsig ntawm cov khoom tiav. Qhov teeb meem tseem ceeb hauv qhov teeb meem no yog qhov tsis sib xws ntawm qhov loj me me, qhov sib txawv tseem ceeb hauv cov duab siv lead ua, thiab kev hloov pauv hauv batch zoo. Qhov no ua rau cov cuab yeej luv luv, sib sib zog nqus khawb ntawm qhov chaw txiav, thiab txo qis sintered bonding zog. Txhawm rau daws cov teeb meem no, peb tsom mus rau kev ua kom muaj kev ruaj ntseg ntawm peb qhov kev qhia: seb qhov particle loj faib (PSD) puas yog, seb lub zog siv lead ua (TI / TTI) puas ruaj khov, thiab seb puas muaj cov ntawv qhia ua tiav.
Xyoo 2023, ib lub tuam txhab pom hniav nyob rau sab qab teb Tuam Tshoj pom qhov poob ntawm cov khoom tsim nyog tus nqi tom qab siv qee tus neeg muag khoom 40/50 mesh pob zeb diamond. Thaum kuaj, nws tau pom tias tus nqi D90 ntawm cov pob zeb diamond no tau dhau tus qauv los ntawm 15 μm, qhov feem pua ntawm equiaxed crystals tsuas yog 62%, thiab tsis muaj TI tus nqi txheeb xyuas. Cov khoom ntxhib ua rau muaj qhov nce hauv kev ua haujlwm siab, thiab cov khoom siv tsis sib xws tau muaj zog sib txuas tsis muaj zog hauv cov hlau substrate, ua rau 28% txo qis hauv lub neej ntawm cov saw hniav. Tom qab cov neeg siv khoom no tau hloov mus rau kev siv Tuam Tshoj Super Tech cov khoom, peb tau ua tiav qhov kev faib tawm nruj me me thiab kev tshuaj ntsuam morphology, nce qhov feem pua ntawm equiaxed crystals mus rau ntau dua 85% thiab tswj cov coefficient ntawm kev hloov pauv (CV tus nqi) ntawm cov khoom siv li ntawm 3%, yog li rov kho cov khoom lag luam ib txwm muaj.
Tuam Tshoj Super Tech Co., Ltd. tshwj xeeb hauvdag pob zeb diamond, titanium alloys, niobium-tantalum thiab lwm yam tshwj xeeb refractory hlau. Hais txog qhov hloov pauv ntawm pob zeb diamond zoo, peb ua raws li tus txheej txheem tswj kev tswj hwm zoo. Nyob rau hauv cov nqe lus ntawm particle loj tswj, peb ntiav multi-theem txheem sieves thiab centrifugal huab cua txaus faib, thiab ua ib tug tag nrho soj ntsuam ntawm PSD siv lub laser particle loj analyzer (ISO 13320). Peb nruj me ntsis tswj lub ultra- loj particle diameters ntawm D90/D97. Hais txog kev tswj hwm siv lead ua, peb tshuaj ntsuam los ntawm crushing thiab shaping thiab cov duab tsom xam txoj kev, tshem tawm flake thiab koob -zoo li tus crystals, kom ntseeg tau tias qhov kev faib ua feem ntawm equiaxed block crystals ua tau raws li cov qauv. Txhua batch ntawm cov khoom tau dhau los ntawm TI (toughness index) thiab TTI (thermal toughness index) kev ntsuam xyuas, thiab yog nrog los ntawm ib daim ntawv qhia tiav COA nrog rau cov ntsiab lus ntawm cov khoom sib nqus (tsawg dua lossis sib npaug li 200 ppm).
Peb muaj ntau yam hauv - cov khoom siv hauv Tshuag thiab muaj peev xwm rau kev hloov kho. Peb lub tsev khaws khoom ib txwm muaj cov qauv mesh qhov ntau thiab tsawg (30/40 txog 325/400 US Mesh) ntawm pob zeb diamond hluavtaws, titanium alloy (Gr1-Gr5/Ti6Al4V, thiab lwm yam) thiab niobium-tantalum hlau cov ntaub ntawv hauv Tshuag. Rau cov qauv khoom xaj, peb txhawb nqa sai. Tib lub sijhawm, peb muab cov kev pabcuam customized, muaj peev xwm ua tau tshwj xeeb qhov loj me ntawm micro- hmoov, nto metallization (Ni/Ti/Cu plating) ntawm pob zeb diamond, thiab tsis yog - tus qauv- loj titanium, niobium, thiab tantalum khoom. Tus qauv muab khoom ib-nres no txo cov theem kev yuav khoom thiab xa khoom txaus ntshai rau cov neeg siv khoom.
Los ntawm kev tswj xyuas meej ntawm qhov loj me me, cov ntaub ntawv siv lead ua ruaj khov, thiab cov khoom siv ntawm ntau hom hlau, Tuam Tshoj Super Tech muab cov khoom siv txhim khu kev qha rau cov tuam txhab lag luam. Peb tswj hwm qhov sib txawv los ntawm qhov chaw los xyuas kom meej tias cov kev qhia ntawm txhua pawg ntawm cov khoom ua tau raws li cov qauv kev thov thoob ntiaj teb, thiab ua tau raws li cov kev xav tau ntawm cov neeg siv khoom thoob ntiaj teb hauv thaj chaw xws li pob zeb txiav, nyuaj alloy sib tsoo, thiab cov khoom siv hauv aerospace.
Tiv tauj peb hnub no rau kev tsocai thiab daim tshev Tshuag.

Q1: Particle Size Distribution (PSD) yog dab tsi thiab vim li cas nws tseem ceeb rau cov pob zeb diamond hluavtaws?
A: PSD piav qhia txog qhov sib txawv ntawm cov kab uas hla hauv pob zeb diamond batch, feem ntau pom tias yog D10 / D50 / D90 qhov tseem ceeb los ntawm kev tsom xam laser diffraction (ISO 13320). Qhov nqaim, zoo- tswj PSD tiv thaiv cov khoom loj loj uas ua rau khawb lossis cov cuab yeej puas tsuaj thiab ua kom ntseeg tau tias txawm tias daim ntawv cog lus khaws cia hauv cov cuab yeej pob zeb diamond. Tuam Tshoj Super Tech muab tag nrho cov ntaub ntawv PSD nrog txhua qhov ntau.
Q2: TI thiab TTi txhais li cas ntawm daim ntawv qhia txog pob zeb diamond abrasive?
A: TI (Toughness Index) yog qhov feem pua ntawm cov pob zeb diamond nplej uas muaj sia nyob ntawm qhov kev ntsuas kev cuam tshuam tus qauv- siab dua TI txhais tau tias zoo dua rau kev puas tsuaj hauv kev sib tsoo lossis sawing. TTi (Thermal Toughness Index) yog TI ntsuas tom qab cua sov cov qauv mus rau ~ 1100℃rau 10 min, simulating siab -temp sintering tej yam kev mob. Ob qhov txiaj ntsig qhia seb lub pob zeb diamond yuav tuav hauv koj daim ntawv cog lus thiab daim ntawv thov. Peb muab TI / TTi cov ntaub ntawv hauv txhua COA.
