Phlogopite
Huajing yas-qib mica hmoov, uas yog siv rau hauv tsev kho mob plastics kom ua rau kom cov kev sib tsoo thiab qhov yooj; kom txo qis ntsws .Nyob hauv cov khoom siv ntawm cov khoom siv hluav taws xob yas, tom qab ntxiv mica, lawv tuaj yeem ua kom zoo dua nrog kev tsim qauv. nws tuaj yeem txhim kho huab cua tiv thaiv ntawm cov khoom yas, kom cov tshuab hluav taws xob tiv thaiv hluav taws xob tuaj yeem tiv thaiv qhov kub thiab txias ntau dua thiab ib puag ncig sib txawv; nws zoo heev txhim kho lub rwb thaiv tsev kom ntseeg tau qhov kev cia siab ntawm kev ua haujlwm ntawm hluav taws xob siab; Nws tuaj yeem txhim kho qhov kev hloov pauv ntawm qee yam khoom yas tshwj xeeb.
Kub mica feem ntau yog daj, xim av, xim av tsaus lossis xim dub; iav luster, cleavage nto yog hlaws lossis lus npliag. Lub pob tshab ntawm Muscovite yog 71.7-87.5%, thiab ntawm phlogopite yog 0-25.2%. Mohs hardness ntawm Muscovite yog 2-2.5 thiab ntawm phlogopite yog 2.78-2.85.
Lub elasticity thiab thaj chaw ntawm Muscovite tsis hloov thaum rhaub ntawm 100,600C, tab sis lub cev qhuav dej, cov khoom siv tshuab thiab hluav taws xob hloov tom qab 700C, lub elasticity ploj thiab ua nkig, thiab cov qauv rhuav tshem ntawm 1050 ° C. thaum Muscovite yog li 700 C, qhov kev ntsuas hluav taws xob zoo dua li Muscovite.
Yog li no, kub mica siv rau hauv plastics uas tsis muaj qhov xav tau siab rau xim tab sis siab kub ua hauj.
Ntawv thov ntawm Mica hauv PA
PA muaj qhov cuam tshuam tsawg zog thiab lub zog nqus ntawm kub thiab tsawg kub, uas cuam tshuam nws qhov ntev thiab qhov ruaj ntseg thiab cov khoom hluav taws xob. Yog li, nws yog qhov yuav tsum tau hloov kho cov shortcomings ntawm PA txhob txwm.
Mica yog qhov zoo tshaj plaws inorganic muab tub lim rau cov plastics, uas muaj cov yam ntxwv ntawm huab cua zoo tiv thaiv, tiv tshav kub, tshuaj tiv thaiv corrosion, kev nruj, hluav taws xob rwb thaiv tsev thiab lwm yam. Nws muaj cov qauv flaky thiab tuaj yeem txhim kho PA rau ob qhov ntev. Tom qab kev hloov kho saum npoo, mica tau ntxiv rau PA resin, cov khoom siv kho tshuab thiab thermal stability tau zoo heev, cov tshuab molding qis dua tseem ua tau zoo dua, thiab cov nqi tsim khoom tau raug txo ntau heev.
