Nrog rau txoj kev loj hlob ntawm tib neeg, daim ntawv thov cov log tsheb yog dav thiab dav, tsis tsuas yog suav nrog cov cuab yeej siv tsheb thauj mus los xws li tsheb kauj vab, tsheb, tsheb ua liaj ua teb, tab sis kuj suav nrog cov khoom lag luam tshiab xws li cov menyuam yaus strollers, cov khoom ua si tsheb, tsheb sib npaug, thiab lwm yam. Kev siv sib txawv muaj cov kev xav tau sib txawv rau cov log tsheb.Thiab lub teeb magnesium oxide yog ib qho tseem ceeb ntxiv uas tuaj yeem txhim kho cov log tsheb zoo.
Lub teeb magnesium oxide yog dab tsi?
Lub teeb magnesium oxide yog dawb xoob amorphous hmoov, tsis muaj ntxhiab, tsis qab, thiab tsis muaj tshuaj lom.Nws qhov ntim yog li peb npaug ntawm qhov hnyav magnesium oxide, thiab nws yog ib qho kev sib xyaw inorganic.Lub teeb magnesium oxide muaj ntau yam kev siv hauv kev lag luam xws li log tsheb, roj hmab, ceramics, khoom siv hauv tsev, metallurgy, tshuaj lom neeg kev lag luam, zaub mov, tshuaj, thiab lwm yam.
Dab tsi yog cov haujlwm ntawm lub teeb magnesium oxide hauv cov log tsheb?
Lub teeb magnesium oxide tuaj yeem ua ntau yam haujlwm hauv cov txheej txheem tsim cov log tsheb, xws li:
- Scorch retarder: tiv thaiv cov roj hmab los ntawm overheating thiab coking thaum ua.
- Vulcanization accelerator: ceev cov tshuaj tiv thaiv vulcanization thiab txhim kho cov vulcanization efficiency.
- Acid absorber: neutralize cov kua qaub hauv cov roj hmab, tiv thaiv kev laus thiab corrosion.
- Filler: nce qhov ntim thiab ntom ntawm cov roj hmab, txo tus nqi.
- Kev kub siab ua haujlwm: txhim kho kev ruaj ntseg thiab kev nyab xeeb ntawm cov log tsheb hauv qhov kub thiab txias.
- Hluav taws kub retardant: txo qhov kub ceev thiab cov pa luam yeeb tsim ntawm cov log tsheb thaum ntsib hluav taws.
- Corrosion resistance: tiv thaiv kev yaig ntawm lwm yam xws li ya raws, ntsev, kua qaub thiab alkali.
Tsis tas li ntawd, lub teeb magnesium oxide kuj muaj qee yam kev ua ub no, uas yog qhov tsim nyog rau kev txhim kho cov kev ua tau zoo ntawm cov log tsheb, xws li:
- Ncua sij hawm scorch: nce qhov yooj thiab hnav tsis kam ntawm cov log tsheb.
- Tswj cov roj hmab cov ntsiab lus thiab adhesion kev ua tau zoo: optimize lub cev lub zog ntawm cov roj hmab, sib npaug tensile lub zog thiab dynamic compression deformation thiab kub tsim teeb meem, txo qhov tsis zoo.
- Tiv thaiv cov log tsheb tawg thiab lub log hub detachment: txhim kho kev ntseeg tau thiab kev nyab xeeb ntawm cov log tsheb thaum khiav ntawm kev kub ceev lossis hnyav.
Kuv yuav tsum xyuam xim rau dab tsi thaum siv lub teeb magnesium oxide?
Txawm hais tias lub teeb magnesium oxide muaj ntau yam txiaj ntsig rau cov log tsheb, qee cov ntsiab lus yuav tsum tau them sai sai rau thaum siv kom tsis txhob muaj kev phiv, xws li:
- Kev kho dej noo: Thaum lub teeb magnesium oxide dampened, nws yuav ua rau hydrochloric acid insoluble teeb meem thiab dej-soluble teeb meem siab dhau, ua rau blistering, xuab zeb qhov muag thiab lwm yam tshwm sim.
- Magnesium oxide tswj cov ntsiab lus: cov ntsiab lus magnesium oxide tsawg dhau yuav cuam tshuam rau lub zog thiab hnav tsis kam ntawm cov log tsheb;siab dhau lawm yuav ua rau kom hardness thiab nruj, txo elasticity thiab ductility.
- Kev tswj cov ntsiab lus calcium: cov ntsiab lus calcium ntau dhau yuav ua rau cov log tsheb nkig thiab ua rau tawg.
- Kev tswj hwm ntau npaum li cas: ntau npaum li cas yuav ua rau muaj kev sib txuas ceev, ua rau lub sij hawm luv luv thiab lub sij hawm vulcanization zoo, cuam tshuam lub zog tensile, ruaj nrees txuas ntxiv thiab hardness, elongation;ntau npaum li cas yuav txo tau crosslinking ceev, Ua rau lub sij hawm ntev scorch thiab lub sij hawm zoo vulcanization, cuam tshuam rau lub log hnav tsis kam, kev laus tsis kam thiab roj tsis kam.
Yog li ntawd, thaum xaiv thiab khaws cia lub teeb magnesium oxide, koj yuav tsum tau them nyiaj tshwj xeeb rau kev xaiv qhov tsim nyog ntau yam thiab cov lus qhia tshwj xeeb, ua kom ib puag ncig qhuav thiab kaw, ntxiv raws li kev faib ua feem thiab txoj hauv kev, txhawm rau ua tiav cov txiaj ntsig zoo tshaj plaws ntawm lub teeb magnesium oxide. hauv log tsheb.
