Hauv cov teb tsim khoom siab xws li semiconductors thiab precision optics, granite slicing bases tau dhau los ua cov khoom tseem ceeb ntawm cov khoom siv tseem ceeb vim lawv qhov ruaj khov zoo heev thiab hnav tsis kam. Txawm li cas los xij, kev ua lag luam puv nrog cov khoom cuav thiab cov khoom tsis zoo uas ua rau marble, pob zeb dag thiab txawm tias pob zeb dyed, uas tsis tsuas yog ua rau qhov tseeb ntawm cov khoom siv poob qis, tab sis kuj tseem yuav ua rau muaj kev poob loj heev. Tsab xov xwm no muab cov lus qhia txog kev txheeb xyuas kev tshawb fawb los ntawm peb qhov ntev: cov khoom siv, cov txheej txheem sim, thiab cov txheej txheem pov thawj, los pab koj zam kev ntxiab ntawm cov neeg siv khoom.
I. Cov Yam Ntxwv ntawm Cov Khoom Siv: Kev Paub Txog Kev Txheeb Xyuas Kev Nkaum
1. Cov ntsuas tawv ntawm qhov ceev thiab qhov nyuaj
Pob zeb granite tiag: Nws qhov ceev feem ntau yog ntawm 2600 thiab 3100kg/m³ (cov pob zeb granite dub zoo xws li cov khoom ZHHIMG® tuaj yeem ncav cuag ntau dua 3000kg/m³), nrog rau Mohs hardness ntawm 6 txog 7. Thaum ib lub npib raug khawb hla nws qhov chaw, tsis muaj qhov seem tshuav.
Khoom cuav: Qhov ceev ntawm marble yog kwv yees li 2500-2700kg / m³, thiab nws qhov nyuaj tsuas yog 3-5 qib. Ib qho khawb me me ntawm lub npib tawm ib qho cim. Qhov ceev ntawm cov pob zeb dag hloov pauv ntau heev thiab nws ua rau lub suab tsis zoo thaum ntaus (thaum cov granite tiag tiag ua rau lub suab meej).
2. Qhov sib txawv ntawm cov qauv thiab cov qauv me me
Granite Ntuj: Nws yog tsim los ntawm cov khoom me me xws li quartz thiab feldspar uas sib txuas ua ke. Nws cov qauv muaj cov pob zeb tsis sib xws lossis cov kab txaij, thiab nws qhov seem yog ntxhib nrog qhov xav tias granular.
Pob zeb uas muaj xim zas: Qhov saum npoo ntawm pob zeb tsis ci ntsa iab. Nws yuav ploj thaum so nrog cawv, thiab xim ntawm qhov seem ntawm pob zeb txawv ntawm qhov saum npoo ntawm pob zeb. Qhov saum npoo ntawm pob zeb feem ntau yog cov kab txaij sib txuas thiab muaj cov calcium carbonate crystals (uas yuav npuas thaum dilute hydrochloric acid poob rau ntawm lawv).
II. Kev Ntsuas Txog Kev Tshawb Fawb: Kev Tshawb Pom Cov Lus Dag Nrog Cov Ntaub Ntawv
1. Kev xeem ua tau zoo yooj yim
2. Kev txheeb xyuas cov cuab yeej tshaj lij
Kev kuaj pom qhov tsis zoo ntawm ultrasonic: Cov granite tiag tiag tsis qhia qhov tsis zoo uas pom tseeb sab hauv, thaum cov khoom cuav yuav muaj cov kab nrib pleb lossis cov duab tsis pom.
Kev tshuaj xyuas X-ray diffraction: Nws tuaj yeem txiav txim siab qhov sib xyaw ua ke ntawm cov pob zeb hauv av (granite feem ntau muaj quartz thiab feldspar, thaum marble feem ntau yog tsim los ntawm calcite).
Iii. Lub Txheej Txheem Kev Pov Thawj: Daim ntawv pov thawj raug cai rau Kev Tiv Thaiv Kev Pheej Hmoo
Daim ntawv teev cov ntaub ntawv yuav tsum tau kuaj xyuas
Cov pov thawj ntawm kev taug qab cov leeg ntawm cov hlau: Rau cov granite tiag tiag, cov ntaub ntawv tshwj xeeb txog qhov chaw txua zeb yuav tsum tau muab (xws li Shandong Jinan Black, Indian Black).
Daim ntawv qhia txog kev xeem ntawm tus neeg thib peb: suav nrog cov ntaub ntawv tseem ceeb xws li qhov ceev, qhov nyuaj, thiab qhov coefficient ntawm thermal expansion (muab los ntawm CNAS lossis ISO 17025 certified laboratory);
Daim Ntawv Pov Thawj Zoo ISO: Cov chaw tsim khoom ib txwm yuav tsum dhau daim ntawv pov thawj ISO 9001 kev tswj hwm zoo, thiab cov khoom lag luam siab yuav tsum muaj daim ntawv pov thawj ib puag ncig ISO 14001 nrog.
2. Ceev faj txog cov ntxiab ntawm kev tshaj tawm cuav
Cov khoom uas hais tias yog "pob zeb siv tau txhua yam" lossis "qhov nyuaj tshaj plaws" feem ntau yog cov khoom siv dag.
Cov hauv paus uas tsis muaj cov kev cai tshwj xeeb (xws li qhov tiaj tiaj thiab qhov ncaj) yuav tsum tau yuav nrog kev ceev faj.
Cov khoom uas muaj tus nqi qis dua 30% ntawm qhov nruab nrab ntawm kev ua lag luam feem ntau yog cov khoom cuav lossis tsis zoo.
