dawb quartz

Koj puas paub tias feem ntau ntawm lub ntiaj teb pob zeb yog nyob los ntawm cov khoom xws li silicon dioxide? Tam sim no xav txog tias qhov no yog tib yam dawb quartz, uas tseem hu ua silica. Raws li lub pob zeb hniav nyiaj hniav kub, nws yog ib qho siv lead ua ntawm cov xim dawb los yog mis nyuj, uas, ntxiv rau nws cov tsos zoo nkauj, kuj muaj kev kho mob thiab tej yam yees siv.

piav qhia

Dawb dawb quartz siv lead ua tsis muaj qhov tsis xws luag yog qhov tsawg thiab muaj nuj nqis heev hauv kev lag luam hniav nyiaj hniav kub. Raws li txoj cai, txhawm rau siv cov pob zeb hauv av los ua ib qho ntxig rau hauv cov hniav nyiaj hniav kub, nws qhov loj me yuav tsum yog ntau tshaj 5 cm. Nyob rau hauv qhov xwm txheej, lawv tau tsim nyob rau hauv daim ntawv ntawm prism los yog trapezoid. Feem ntau koj tuaj yeem pom cov pob zeb ntxaib.

Hom pob zeb muaj xws li:

• rhinestone;
• mis nyuj quartz;
• qab zib (dawb) quartz;
• binhemite.

Lub pov haum yog suav tias yog qhov ruaj khov heev: txhawm rau faib nws, koj yuav xav tau cov txheej txheem tshwj xeeb. Tsis tas li ntawd, nws yog heev resistant rau acids thiab alkalis. Qhov tsawg kawg nkaus melting point yog 1500 ° C.

Tag nrho cov muaju ntawm ntuj dawb quartz yog tus cwj pwm los ntawm cov coefficient siab ntawm thermal conductivity, nrog rau muaj cov khoom piezoelectric, vim tias cov pob zeb hauv av muaj peev xwm tsim hluav taws xob tsis muaj zog.

Свойства

Dawb quartz, zoo li tag nrho cov ntxhia hauv ntuj, muaj qee yam muaj txiaj ntsig zoo uas tso cai rau nws siv rau hauv kev ua lwm yam tshuaj thiab tej yam yees siv.

Ib qho ntawm feem nrov "tshuaj" yog dej quartz. Rau nws cov kev npaj, nws yog ib qhov tsim nyog rau immerse cov ntxhia hauv dej huv rau ib hnub thiab haus nws txhua hnub. Ua li no, koj tuaj yeem txhim kho kev ua haujlwm ntawm tag nrho cov kabmob thiab cov kab ke hauv tib neeg lub cev thiab tiv thaiv kev laus ntxov ntxov. Tsis tas li ntawd, cov khoom kho mob ntawm dawb quartz muaj xws li:

• saturates hlwb nrog oxygen;
• ntxuav lub cev ua pa;
• tiv thaiv kab mob khaub thuas thiab mob khaub thuas, ntxiv dag zog rau lub cev;
• tiv thaiv qhov tshwm sim ntawm kev tsis haum tshuaj;
• activates kev ua haujlwm ntawm endocrine system, txhim kho kev ua haujlwm ntawm lub plab zom mov;
• kho cov kab mob ntawm daim tawv nqaij;
• pab rov qab nco;
• zoo cuam tshuam rau kev ua haujlwm ntawm lub hauv nruab nrab paj hlwb.

Txij li thaum ancient sij hawm, pob zeb dawb tau siv rau kev sib txuas lus ntawm cov neeg nyob thiab lwm lub ntiaj teb. Yog li ntawd, txawm niaj hnub no nws feem ntau siv los tsim kev sib raug zoo nrog lwm tus. Lub pov haum pab tswj kev sib raug zoo, zam kev ntxeev siab thiab kev nkag siab yuam kev. Tsis tas li ntawd, nws muaj peev xwm txhim kho kev xav, txhim kho kev xav, tshem tawm lub siab ntawm kev xav phem thiab nrhiav kev thaj yeeb ntawm lub siab.

Daim ntawv thov

Txog niaj hnub no, cov hlaws dai, bracelets, rings, tsej thiab lwm yam hniav nyiaj hniav kub yog ua nrog dawb quartz. Lub thav duab tuaj yeem ua tau ntau yam: kub, nyiaj, tawv, kho mob alloys. Raws li rau kev txiav, classic ib yog ntau dua ntawm no - cabochon, oval, pob. Tab sis feem ntau koj tuaj yeem pom cov kev xaiv kauj ruam, ntau fantasy.

Jewellery tsis yog qhov chaw tseem ceeb ntawm kev siv dawb quartz. Muab lub siab coefficient ntawm thermal conductivity ntawm pob zeb, nws tuaj yeem pom nyob rau hauv da dej thiab saunas. Tsis tas li ntawd, cov ntxhia yog siv rau hauv kev tsim cov fibers optical, semiconductors thiab LEDs.

Mus nplua

Dawb quartz suits Libra, Scorpio thiab Aquarius. Lawv lub zog zoo sib xws, yog li astrologers pom zoo kom tsis tu ncua nqa lub pob zeb nrog koj nyob rau hauv thiaj li yuav mloog zoo rau cov teeb meem tseem ceeb thiab tig mus rau txoj cai nthwv dej. Raws li ib tug amulet, cov pob zeb dawb yog pom zoo rau Sagittarius, Aries thiab tsov ntxhuav, tab sis koj yuav tsum tsis txhob hnav nws txhua lub sijhawm, muab cov pob zeb hauv av tawg los ntawm cov ntaub ntawv tau txais lub zog ib ntus.
