Technological Properties ntawm Acrylic Phaj
Dec 21, 2022| Acrylic phaj muaj lub pob tshab ntawm cov siv lead ua, thiab lub teeb xa hluav taws xob ntau dua 92 feem pua. Acrylic phaj dyed nrog dye muaj cov xim zoo nkauj. Tsis tas li ntawd, acrylic phaj: muaj cov huab cua zoo heev, siab hardness thiab luster, thiab zoo kub kuj. Acrylic phaj muaj kev ua tau zoo, uas tuaj yeem muab faib ua ob hom: hom casting thiab extrusion hom raws li cov txheej txheem ntau lawm. Ob leeg thermoforming (xws li molding, tshuab moulding thiab lub tshuab nqus tsev blistering) thiab kev siv tshuab xws li drilling, tig, milling thiab txiav tuaj yeem siv tau. Lub tshuab txiav, scraping thiab carving tswj los ntawm microcomputer tsis tsuas yog txhim kho kev ua tau zoo, tab sis kuj tuaj yeem tsim cov qauv zoo nkauj thiab cov duab ntau dua li cov txheej txheem ib txwm muaj. Tsis tas li ntawd, acrylic daim hlau tuaj yeem txiav thiab carved los ntawm laser los tsim cov khoom nrog cov teebmeem tshwj xeeb.
Hardness yog ib qho ntawm qhov tsis zoo uas tuaj yeem cuam tshuam cov txheej txheem tsim khoom thiab thev naus laus zis ntawm cam khwb cia acrylic phaj, thiab yog ib feem tseem ceeb ntawm kev tswj kom zoo. Hardness tuaj yeem cuam tshuam qhov purity ntawm raw khoom MMA, huab cua tsis kam thiab kub kub tsis kam ntawm lub phaj. Lub hardness ncaj qha cuam tshuam seb lub phaj yuav ntsws, khoov thiab deform, thiab seb qhov chaw puas yuav tawg thaum ua haujlwm. Hardness yog ib qho nyuaj indexes los txiav txim qhov zoo ntawm acrylic phaj. Cov cam khwb cia acrylic phaj muaj qhov hardness siab tshaj plaws nyob rau tam sim no, nrog rau qhov nruab nrab Rockwell hardness ntawm 90 degrees.
Acrylic board kuj muaj cov huab cua zoo heev, tshwj xeeb tshaj yog rau kev siv sab nraum zoov, qeb duas ntawm lwm cov yas, thiab muaj qhov zoo ntawm qhov tawv tawv thiab luster. Nws muaj cov txheej txheem zoo plasticity thiab tuaj yeem ua rau ntau yam xav tau cov duab thiab cov khoom. Nws daim hlau muaj ntau yam xim (xws li cov xim translucent), thiab lwm qhov tshwj xeeb yog cov phaj tuab tseem tuaj yeem ua kom pom tseeb.
