Ibikoresho byahinduwe neza cyane: Fibre y'ikirahure yahinduwe ya Phenolic Resin (FX-501)

Fenoliki Fibre y'ikirahure, mu ma resins ya kera cyane yakozwe mu nganda, ubusanzwe ni polycondensate ikorwa na polymerization ya phenols na aldehydes imbere y’umusemburo wa alkaline. Hanyuma inyongera zimwe na zimwe zishyirwamo kugira ngo zihuze imiterere ya macromolecular, ziyihinduramo imiterere ya macromolecular idashonga kandi idashonga, bityo ikaba isanzwe. ibikoresho bya polimeri byo gushyiramo thermosetting. Amaresine ya phenolic ahabwa agaciro gakomeye kubera imiterere yayo itangaje, harimo kudakoresha umuriro neza, kudahindagurika mu ngero, ndetse no gukomera neza kwa mekanike. Iyi miterere yatumye habaho ubushakashatsi bwimbitse no gukoresha ibikoresho bya resine ya phenolic glass fibre.

Uko ubukungu bw'inganda butera imbere vuba, ni ko hakenewe byinshi ku mikorere ya phenolic Ibikoresho bya Fibre y'ikirahures. Kubera iyo mpamvu,imigozi y'ikirahure ya phenolic ihamye kandi irinda ubushyuhebirimo gutezwa imbere no gukoreshwa cyane. Resin ya phenolic yahinduwe ikoresheje fibre y'ikirahure (FX-501)ubu ni kimwe mu bikoresho bya resini ya fibre y'ikirahure ya phenolic yahinduwe neza cyane. Ni ubwoko bushya bw'ibikoresho bya phenolic byahinduwe kandi bikomejwe byakozwe binyuze mu gushyiramo fibre y'ikirahure muri matrix ya resini y'umwimerere binyuze mu kuvanga.

Imiterere ya mekanike n'inshingano zayo

Resin y'ibirahuri ya phenolic fibreakenshi itoranywa nk'ikimenyetso cy'isuzuma ibikoresho biramba, bitoroshye kandi bigabanya imbaragabitewe n'imbaraga zayo zo gukurura, kurwanya ibinyabutabire, n'ubushobozi bwayo bwiza bwo gukora nk'ubudahangarwa bw'umuriro. ibikoresho bya matrixahanini ikora nk'icyuma gihuza ibice byose mu buryo bw'umwimerere. Indodo z'ikirahurezikora nk'ibice by'ingenzi bitwara imizigo mu bikoresho bidashira, bitanga ubushobozi bwo gutwara imizigo, kandi imikorere yazo myiza igira ingaruka zitaziguye ku ngaruka zo gushimangira kuri matrix.

Inshingano y'ibikoresho bya matrix ni uguhuza neza ibindi bice by'ibikoresho byo gukurura, bigatuma imizigo ikwirakwizwa, igakwirakwizwa, kandi igashyirwa ku migozi itandukanye y'ibirahure. Ibi bitanga imbaraga n'ubukomere ku bikoresho. Imigozi isanzwe, harimo imigozi y'ibirahure, imigozi y'umwimerere, Fibre y'icyumas, hamwe n'imitako y'amabuye y'agaciro, bigira uruhare mu guhindura imbaraga zo gukurura ibikoresho.

Ingano y'umutwaro mu birungo n'ingaruka z'ibirungo bya fibre

Muri sisitemu y'ibikoresho bivanze bya fibre y'ikirahure ya phenolic, byombi insinga na resin ya matrix bitwara umutwaro, hamwe n'imigozi y'ikirahure ikomeza kuba yo itwara imizigo y'ingenzi. Iyo ibinyabutabire bya fenolike mu girahure bihuye n'umuvuduko wo gukanda cyangwa gukanda, umuvuduko uva kuri resine ya matrix ujya kuri fibre y'ikirahure ku giti cyayo binyuze mu gice cy'urukuta, bigatuma imbaraga zigenda zikwirakwira neza. Iyi nzira irushaho kunoza imiterere y'ibikoresho bivanze. Bityo, kwiyongera gukwiye kwa Ingano y'ibirahuri bishobora kongera imbaraga z'ibirungo by'ibirahuri bya phenolic.

Ibisubizo by'igerageza bigaragaza ibi bikurikira:

• Ibikoresho bya fibre y'ikirahure bya phenolic bifite 20% by'ibirahure bya fibreigaragaza ikwirakwira ry’ibinyabutabire ritaringaniye, ndetse hari n’aho bibura ibinyabutabire.
• Ibikoresho bya fibre y'ikirahure bya phenolic bifite 50% by'ibirahure bya fibrebigaragaza ikwirakwira ry’imigozi rimwe, ubuso butaringaniye bwo kwangirika, kandi nta bimenyetso by’uko imigozi myinshi isohoka. Ibi bigaragaza ko imigozi y’ikirahure ishobora kwihanganira umutwaro hamwe, bigatuma imbaraga nyinshi zo kwihuta.
• Iyo ingano y'ibirahuri iri kuri 70%, ingano ikabije ya fibre ituma habaho ingano nto ya resin ya matrix. Ibi bishobora gutera "resine nke" mu duce tumwe na tumwe, bikabangamira ihererekanya ry'imihangayiko no guteza ingano y'imihangayiko mu gace runaka. Kubera iyo mpamvu, imiterere rusange y'ibikoresho bya fenolic glass fibre composite irahinduka. ikunda kugabanuka.

Muri ibi byavumbuwe, Kongeramo fibre y'ikirahure ntarengwa mu bivanze bya fibre y'ikirahure bya phenolic ni 50%.

Ingaruka ku mikorere n'ingaruka zayo

Dukurikije imibare, ibinyabutabire bya fenolike bigizwe na fibre y'ikirahure ya 50%kwerekana hafi imbaraga zo gucika intege zikubye gatatuna inshuro enye z'imbaraga zo kwitsindagiraugereranije na resin ya phenolic yonyine. Byongeye kandi, izindi mpamvu zigira ingaruka ku mbaraga za plastiki zikomejwe na fibre y'ikirahure ya phenolic zirimo uburebure bw'imigozi y'ikirahuren'ibyabo icyerekezo.
