Xaiv Marble, Quartz Pob zeb lossis Granite rau Lub Rooj Zaum Ntawm Lub Txee?
Hauv qhov teeb meem no, cia peb nthuav cov kev paub ntawm cov khoom siv kho kom zoo nkauj hauv tsev.
Ua ntej tshaj plaws, cia peb hais txog qhov xwm txheej tam sim no ntawm kev lag luam: cov khoom siv hauv tsev kev lag luam yog qhov sib xyaw ntawm cov ntses thiab cov zaj thiab ntau cov ntses ntau dua li lwm cov kev lag luam. Qhov teeb meem no feem ntau yog vim cov ntaub ntawv asymmetry. Qhov txawv yog tias peb yuav zaub thiab khaub ncaws. Qhov zoo los yog phem. Feem ntau, txhua tus neeg yuav muaj kev paub meej. Txawm tias tsis muaj kev paub txog, peb tuaj yeem pom tau zoo los ntawm kev paub. Txawm li cas los xij, piv nrog cov khoom siv kho kom zoo nkauj hauv tsev, cov neeg feem coob tuaj yeem kho lub tsev nyob rau hauv lawv lub neej tag nrho, tsis muaj kev paub zoo, thiab cov ntaub ntawv hauv tsev muaj feem cuam tshuam, uas ua rau cov ntaub ntawv tsis txaus ntseeg ntawm cov tub lag luam. Nyob rau hauv txoj kev no, cov neeg siv khoom yooj yim rau kev dag.
Txoj hauv kev zoo los tiv thaiv kev dag yog kom nkag siab koj tus kheej. Qhov no kuj yog qhov peb ib txwm hais txog. Yog tias koj xav txuag nyiaj thiab tiv thaiv pits hauv kev kho kom zoo nkauj, koj yuav tsum ua kom muaj qee yam kev paub txog kev kho kom zoo nkauj. Tsuav koj nkag siab nws, koj yuav tsis raug dag.
Niaj hnub no, cia peb tham txog lub tsev kho kom zoo nkauj pob zeb. Pob zeb feem ntau muab faib ua pob zeb ntuj thiab pob zeb dag. Muaj peb hom pob zeb ntuj uas feem ntau siv hauv tsev kho kom zoo nkauj:marble, quartz pob zebthiabgranite.
Marble:Ameslikas hais txog cov limestone dawb nrog cov qauv dub uas tsim nyob rau hauv Dali, Yunnan Province. Tom qab ntawd, lub npe marble maj mam tsim rau hauv lub npe rau tag nrho cov limestone nrog ntau yam xim thiab cov qauv siv los ua cov khoom siv kho kom zoo nkauj. Los ntawm Mongolian dub (Fengzhen dub) los ntawm Inner Mongolia mus rau Yazhou liab los ntawm Hainan Province; Los ntawm Dandong ntsuab hauv Liaoning mus rau Tianshan xiav hauv Xinjiang, ntau tshaj 30 lub xeev thiab nroog hauv Suav teb muaj marble, feem ntau yog Beijing Fangshan dawb marble; Anhui Huaining thiab Guichi dawb marble; Hebei Quyang thiab Laiyuan dawb marble; Sichuan Baoxing Shu dawb jade; Jiangsu Ganyu dawb marble; Cangshan dawb marble hauv Dali, Yunnan; Shandong Pingdu thiab Laizhou daus dawb; Gansu Longnan dawb jade; Hezhou dawb hauv Hezhou, Guangxi, thiab lwm yam.
1. Qhov zoo: tus nqi nruab nrab, pheej yig dua.
2. Qhov tsis zoo: lub hardness yog tsis txaus, thiab nws yog ib qho yooj yim los tsim khawb thiab pits nyob rau hauv kev sib tsoo ntawm cov cuab yeej txiav.
Quartz pob zeb:Feem ntau hais lus, quartz pob zeb yog ib yam tshiab ntawm pob zeb ua ke los ntawm ntau dua 90 feem pua quartz siv lead ua ntxiv rau cov cob thiab lwm yam kab. Nws yog lub phaj loj loj nias los ntawm lub tshuab tshwj xeeb nyob rau hauv qee yam ntawm lub cev thiab tshuaj lom neeg. Nws cov khoom tseem ceeb yog quartz.
1. Qhov zoo: lub hardness yog siab dua li ntawm marble, nws tsis yooj yim los tsim khawb, qhov ntom yog loj, thiab cov kua tsis yooj yim rau yaj hauv.
2. Qhov tsis zoo: kuj yog nkig, yooj yim tawg, yooj yim rau stains nrog roj thiab hmoov av rau lub sijhawm ntev, tsis tiv taus cov av, ua rau stains thiab nyuaj heev hauv kev tu.
Granite:granite yog ib hom lava los ntawm volcanic eruption, uas nce mus rau saum npoo ntawm lub ntiaj teb crust nyob rau hauv lub siab ntau heev. Nws yog ib hom plutonic acid igneous pob zeb thiab belongs rau magmatic pob zeb (igneous pob zeb). Granite yog tsim los ntawm quartz, feldspar thiab mica. Cov chaw tsim khoom tseem ceeb yog chrysanthemum ntsuab, snowflake ntsuab thiab yunlimei hauv Yanshi, Henan, Jinan ntsuab hauv Jinan, Shandong, Linzhou ntsuab, Linzhou ntsuab thiab hav zoov ntsuab hauv Linzhou, Anyang, asbestos hauv Sichuan, taum ntsuab hauv Shanggao, Jiangxi, Zhongshan jade nyob rau hauv Zhongshan, Guangdong, imperial concubine liab nyob rau hauv Lingqiu, Shanxi, txiv kab ntxwv, hemp dawb, ntsuab dub paj, daj dub paj, thiab lwm yam.
1. Qhov zoo: siab hardness, hnav tsis kam, tiv thaiv roj thiab dej to.
2. Qhov tsis zoo: tus nqi qis thiab tus nqi siab.
Qhov kev xaiv ntawm cov nqi tsim nyog rau lub rooj quartz pob zeb yog qhov kev xaiv zoo dua, thiab granite tuaj yeem xaiv nrog qee qhov kev lag luam hauv paus. Hauv kev muag khoom tiag tiag, ntau lub lag luam yooj yim tshaj tawm cov hluav taws xob ntawm cov pob zeb ntuj, ua rau muaj kev ntshai rau cov neeg siv khoom, kom cov neeg siv khoom tuaj yeem yuav cov khoom pom zoo nrog cov txiaj ntsig loj. Qhov tseeb, lub tuam tsev saib xyuas kev noj qab haus huv zoo hauv lub tebchaws thiab lub koom haum ntawm kev tsim qauv tau sib koom ua ke tawm ib daim ntawv los hais tawm cov lus xaiv tias ntuj pob zeb yuav tawg mus rau qee qhov, tab sis cov hluav taws xob me me thiab yuav tsis muaj kev cuam tshuam rau tib neeg lub cev.
