Zochita Zopambana Kwambiri: Ulusi Wagalasi Wolimbikitsidwa Wa Phenolic Resin (FX-501)

Ndi chitukuko mofulumira m'munda wa engineered galasi CHIKWANGWANI analimbitsa mapulasitiki,phenolic resin-based materialszagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Izi ndichifukwa cha mawonekedwe awo apadera, mphamvu zamakina apamwamba, komanso magwiridwe antchito abwino kwambiri. Chimodzi mwazinthu zofunikira kwambiri zoyimira ndiphenolic galasi CHIKWANGWANI utomoni zakuthupi.

Phenolic glass fiber, pakati pa ma resin akale opangira mafakitale, nthawi zambiri amakhala polycondensate yopangidwa ndi polymerization ya phenols ndi aldehydes pamaso pa chothandizira zamchere. Zowonjezera zina zimayambitsidwa kuti zigwirizane ndi mawonekedwe a macromolecular, ndikuzisintha kukhala zosasunthika komanso zosasunthika zamagulu atatu a macromolecular, motero zimakhala zofanana.thermosetting polima zinthu. Phenolic resins amayamikiridwa kwambiri chifukwa cha mawonekedwe ake apamwamba, kuphatikiza kuchedwa kwamoto, kukhazikika kwa mawonekedwe, komanso mphamvu zamakina. Izi zathandizira kafukufuku wambiri komanso kugwiritsa ntchito zida za phenolic glass fiber resin.

Pamene chuma cha mafakitale chikupita patsogolo, zofuna zowonjezereka zimayikidwa pakugwira ntchito kwa zipangizo zamagalasi a phenolic. Chifukwa chake,ulusi wagalasi wa phenolic wosinthika kwambiri komanso wosamva kutenthaakupangidwa mozama ndikugwiritsidwa ntchito.Galasi CHIKWANGWANI chinalimbikitsidwa kusinthidwa phenolic utomoni (FX-501)pakali pano ndi chimodzi mwa zinthu zopambana kwambiri zosinthidwa phenolic glass fiber resin. Ndi mtundu watsopano wa zinthu zosinthidwa ndi kulimbikitsidwa za phenolic zomwe zimapangidwa pophatikiza ulusi wagalasi mu matrix oyambirira a utomoni mwa kusakaniza.

 Katundu Wamakina ndi Maudindo Ogwirizana

Phenolic glass fiber resinnthawi zambiri amasankhidwa ngati matrixzosavala, zolimba, komanso zoponderezachifukwa cha kulimba kwake kwamphamvu, kukana zosungunulira, komanso zida zabwino zamakina monga kuzizira kwamoto. Thematrix zinthuimagwira ntchito ngati binder, kulumikiza zigawo zonse.Ulusi wagalasiamagwira ntchito ngati mayunitsi akuluakulu onyamula katundu muzinthu zosavala, zopatsa mphamvu zonyamula katundu, ndipo magwiridwe ake apamwamba amakhudza mwachindunji kulimbikitsa kwa matrix.

Ntchito ya matrix ndi kumangiriza zigawo zina za zinthu zolimba, kuwonetsetsa kuti katundu amasamutsidwa mofanana, kugawidwa, ndikugawidwa kumagulu osiyanasiyana a galasi. Izi zimapereka mphamvu ndi kulimba kwa zinthuzo. Ulusi wamba, kuphatikizapo ulusi wagalasi, ulusi wachilengedwe, ulusi wazitsulo, ndi ulusi wa mineral, umathandizira kusintha mphamvu yazinthuzo.

 Katundu Wonyamula mu Composites ndi Impact of Fiber Content

In phenolic glass fiber composite materialmachitidwe, zonseulusi ndi matrix resin amanyamula katundu, ndi ulusi wa magalasi wotsalira wonyamula katundu. Pamene phenolic glass fiber composites ikugwedezeka kapena kupsinjika maganizo, kupanikizika kumasunthidwa mofanana kuchokera ku utomoni wa matrix kupita ku ulusi wagalasi pamtundu uliwonse, ndikubalalitsa mphamvu yonyamula. Izi bwino mawotchi katundu wa gulu zakuthupi. Chifukwa chake, kukula koyeneraZomwe zili mugalasi zimatha kukulitsa mphamvu ya phenolic glass fiber composites.

Zotsatira zoyeserera zikuwonetsa zotsatirazi:

• Phenolic glass fiber composites yokhala ndi 20% fiber fiberamawonetsa kugawa kwa ulusi wosagwirizana, pomwe madera ena alibe ulusi.
• Phenolic glass fiber composites yokhala ndi 50% fiber fiberwonetsani kagawidwe ka ulusi wofanana, malo osweka osakhazikika, ndipo palibe zizindikiro zazikulu zakukoka kwa ulusi. Izi zikutanthauza kuti ulusi wagalasi ukhoza kunyamula pamodzi, zomwe zimapangitsaapamwamba flexural mphamvu.
• Pamene galasi fiber zili 70%, ulusi wochuluka kwambiri umapangitsa kuti utomoni wa matrix ukhale wochepa kwambiri. Izi zitha kuyambitsa zochitika za "utomoni wosauka" m'malo ena, kulepheretsa kusamutsa kupsinjika ndikupangitsa kuti pakhale kupsinjika komwe kumakhala komweko. Chifukwa chake, mawonekedwe onse amakina a phenolic glass fiber composite materialamakonda kuchepa.

Kuchokera pazopeza izi, aKuwonjezeka kwakukulu kololedwa kwa ulusi wagalasi mu phenolic glass fiber composites ndi 50%.

 Kupititsa patsogolo Magwiridwe Antchito ndi Zinthu Zolimbikitsa

Kuchokera ku data ya manambala,phenolic glass fiber compositesokhala ndi 50% fiber fiberkuwonetsa pafupifupikatatu mphamvu ya flexuralndikanayi compressive mphamvupoyerekeza ndi utomoni weniweni wa phenolic. Kuphatikiza apo, zinthu zina zomwe zimathandizira kulimba kwa mapulasitiki opangidwa ndi phenolic glass fiber ndi awakutalika kwa ulusi wagalasindi awokutsata.
