Lub luag haujlwm tseem ceeb ntawm Mica
Huajing yas-qib mica hmoov, uas yog siv rau engineering plastics kom nce qhov modulus khoov thiab yooj ywm; kom txo qhov shrinkage. Hauv thaj teb ntawm cov khoom siv yas ntawm cov khoom siv hluav taws xob, tom qab ntxiv mica, lawv tuaj yeem ua kom zoo dua ua ke nrog kev tsim qauv. nws tuaj yeem txhim kho huab cua tsis kam ntawm cov khoom yas, yog li ntawd engineering plastics tuaj yeem tiv taus qhov kub thiab txias ntau dua thiab qhov sib txawv ntawm ib puag ncig; nws zoo heev txhim kho qhov rwb thaiv tsev kom ntseeg tau tias muaj kev ntseeg siab ntawm kev ua haujlwm hluav taws xob siab; Nws tuaj yeem txhim kho qhov fluidity ntawm qee cov khoom yas tshwj xeeb thiab.
Cov hmoov av mica ntub dej yog siv los ntxuav cov khoom siv raw nrog dej thiab zom nrog dej ua nruab nrab, yog li cov hmoov av ntub dej muaj cov yam ntxwv zoo dua li cov hmoov av qhuav, xws li dawb zoo, du nto, qhov loj me me, cov duab tsis tu ncua, qhov loj ntawm txoj kab uas hla mus rau qhov tuab thiab lwm yam.
Daim ntawv thov ntawm Mica hauv HDPE
Qhov ntxiv ntawm mica rau hauv HDPE kuj tseem tuaj yeem txo qhov permeability ntawm cov ntaub ntawv, yog li nws yog qhov tsim nyog rau kev ua txhua yam thawv, xws li lub tank roj tsheb thiab lwm yam. Lub modulus shear tsis-dav hlau ntawm HDPE / mica composites nce ntau nrog rau kev nce ntawm qhov sib piv ntawm cov ntawv mica, thaum lub modulus shear tsis-dav hlau txo qis me ntsis. Cov HDPE composites uas muaj hmoov mica puv muaj cov khoom siv kho tshuab zoo dua. Nrog rau kev nce ntawm cov hmoov mica, lub zog tensile, lub zog khoov thiab modulus khoov ntawm cov composites nce.
Daim ntawv thov ntawm Mica Hmoov hauv ABS
ABS tau siv dav hauv kev tsim tsheb, kev sib txuas lus, khoom siv hluav taws xob, kev tiv thaiv lub teb chaws thiab lwm yam. Tom qab ntxiv mica rau hauv ABS engineering plastics, qhov rigidity, hnav tsis kam thiab tshuaj lom neeg ruaj khov ntawm ABS tuaj yeem txhim kho hauv ntau qib sib txawv. Thaum ntxiv 30% mica, piv nrog ABS ntshiab, tus nqi tsim khoom raug txo los ntawm kwv yees li 20%, thiab lub zog khoov thiab lub zog tensile ntawm cov khoom raug txhim kho sib txawv. Thaum cov ntsiab lus ntawm mica yog 20%, qhov modulus khoov ntawm cov khoom yog kwv yees li ob npaug ntawm ABS ntshiab.
