Ubwino wa Glass Fiber mu Graphite-based Chemical Equipment

Graphite imagwiritsidwa ntchito kwambiri popanga zida zamakina chifukwa cha kukana kwa dzimbiri, mphamvu zamagetsi, komanso kukhazikika kwamafuta. Komabe, ma graphite amawonetsa zofooka zamakina, makamaka pakukhudzidwa ndi kugwedezeka.Glass fiber, monga zinthu zogwiritsidwa ntchito kwambiri, zimapereka ubwino waukulu zikagwiritsidwa ntchito ku zipangizo zamakina zopangidwa ndi graphite chifukwa cha kutentha kwake, kukana kwa dzimbiri, ndi makina apamwamba kwambiri. Ubwino wina wake ndi:

(1) Kukhathamiritsa Kwamakina

Mphamvu yamagetsi yagalasi imatha kufika 3,450 MPa, yoposa graphite, yomwe nthawi zambiri imakhala kuyambira 10 mpaka 20 MPa. Pophatikizira ulusi wagalasi muzinthu za graphite, magwiridwe antchito amakina onse amatha kusintha kwambiri, kuphatikiza kukana kukhudzidwa ndi kugwedezeka.

(2) Kusamva dzimbiri

Ulusi wagalasi umawonetsa kukana kwa ma acid ambiri, alkali, ndi zosungunulira. Ngakhale kuti graphite palokha imakhala yosagwira dzimbiri,galasi fiberAtha kupereka magwiridwe antchito apamwamba kwambiri m'malo opangira mankhwala, monga kutentha kwambiri komanso kupanikizika kwambiri, ma oxidizing atmospheres, kapena hydrofluoric acid.

(3) Katundu Wowonjezera Wotentha

Ulusi wagalasi uli ndi coefficient yotsika kwambiri ya kufalikira kwa matenthedwe (CTE) pafupifupi 5.0 × 10−7/°C, kuonetsetsa bata la dimensional pansi pa kupsinjika kwa kutentha. Kuphatikiza apo, malo ake osungunuka kwambiri (1,400-1,600 ° C) amathandizira kukana kutentha kwambiri. Makhalidwewa amathandizira zida za graphite zolimbitsa magalasi kuti zikhalebe zokhazikika komanso zogwira ntchito m'malo otentha kwambiri osasinthika pang'ono.

(4) Kunenepa Kwabwino

Ndi kachulukidwe pafupifupi 2.5 g/cm3, ulusi wagalasi ndi wolemera pang'ono kuposa graphite (2.1-2.3g/cm3) koma wopepuka kwambiri kuposa zida zachitsulo monga chitsulo kapena aluminiyamu. Kuphatikiza ulusi wagalasi mu zida za graphite kumathandizira magwiridwe antchito popanda kuchulukitsa kulemera, kusunga zida zopepuka komanso zosunthika.

(5) Kugwiritsa Ntchito Ndalama

Poyerekeza ndi zida zina zogwira ntchito kwambiri (mwachitsanzo, kaboni fiber), ulusi wamagalasi ndiwotsika mtengo, zomwe zimapangitsa kuti zikhale zopindulitsa pamafakitale akuluakulu:

Mtengo wa Zopangira:Glass fibermakamaka amagwiritsa ntchito galasi lotsika mtengo, pamene mpweya wa carbon umadalira acrylonitrile yodula.

Mitengo Yopangira: Zida zonsezi zimafuna kutentha kwambiri komanso kupanikizika kwambiri, koma kupanga mpweya wa carbon fiber kumaphatikizapo njira zina zovuta (mwachitsanzo, polymerization, oxidation stabilization, carbonization), kuyendetsa mtengo.

Kubwezeretsanso ndi Kutaya: Ulusi wa kaboni ndi wovuta kubwezanso ndipo umabweretsa zoopsa zachilengedwe ngati sunasamalidwe bwino, zomwe zimapangitsa kuti pakhale ndalama zambiri zotayira. Ulusi wagalasi, mosiyana, ndi wosavuta kuwongolera komanso wokometsera zachilengedwe m'mapeto a moyo.
