ABS Txhaj Tshuaj Yas

1. Khoom Qhia Txog

Acrylonitrile Butadiene Styrene (ABS) yog ib qho thermoplastic thermoplastic thiab amorphous polymer. "Thermoplastic" (as opposed to "thermoset") tau ua nrog txoj kev cov khoom teb rau cua sov. Cov thermoplastics ua kua (piv txwv li "iav hloov") ntawm qhov kub (221 degrees Fahrenheit tus case ABS). Lawv tuaj yeem rhuab mus rau lawv qhov chaw txias, txias dua, thiab rov rhaub dua yam tsis muaj teeb meem loj. Tsis txhob hlawv, thermoplastics xws li ABS liquefy uas tso cai rau lawv tau yooj yim txhaj molded thiab ces tom qab siv dua. Ntawm qhov sib txawv, thermoset plastics tsuas ua tau kom sov ib zaug (feem ntau thaum lub caij txhaj tshuaj molding). Thawj cua sov ua rau cov khoom siv thermoset teeb (zoo ib yam li 2-thooj epoxy), ua rau muaj kev hloov tshuaj uas tsis tuaj yeem hloov. Yog tias koj tau sim ua kom sov lub thermoset yas kom kub kub dua zaum thib ob nws yuav tsuas kub nyhiab. Qhov cwj pwm no ua rau cov ntaub ntawv thermoset tsis zoo rau cov khoom ub khoom siv dua tshiab. Cov khoom tseem ceeb yog cov ntsiab lus tseem ceeb uas tsis muaj cov ntsiab lus ntawm crystalline solids.

2. ABS ua li cas?

ABS feem ntau yog polymerized los ntawm cov txheej txheem ntawm emulsion (qhov sib tov ntawm ntau yam khoom uas tsis yog feem ntau ua ke rau hauv ib yam khoom muag). Ib qho piv txwv zoo ntawm cov khoom emulsified yog mis. ABS kuj yog tsim, tsawg dua li qub, los ntawm ib txoj cai uas tau txais kev pom zoo ua tus qauv huab hwm coj polymerization. Ntiaj teb, feem ntau cov kev vib this los tsim ABS yog cov txheej txheem emulsion.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias vim ABS yog cov khoom siv thermoplastic, nws tuaj yeem yooj yim dua qub raws li tau hais los saum no. Qhov no txhais tau hais tias ib qho kev ua ntawm ABS yas yog los ntawm lwm yam yas yas (xws li ua ABS los ntawm ABS).

3. Cov khoom ntawm ABS puas zoo li cas?

ABS yog qhov ua tau zoo heev, uas yog vim li cas nws siv los ua tej yam xws li lub koob thaij duab, qhov chaw tiv thaiv, thiab ntim. Yog tias koj xav tau ib qho pheej yig, muaj zog, tawv yas uas tswj kom zoo rau sab nraud, ABS yog xaiv zoo.
