Kuvuga ko hari ubwoko butandukanye bwibikoresho byicyayi cyicyayi, ibikoresho bisanzwe byicyayi kumasoko ni fibre y'ibigori, ibikoresho bya pp bidoda, ibikoresho byamatungo adoda hamwe nibikoresho byungurura impapuro, na
Impapuro z'icyayi impapuro Abongereza banywa buri munsi. Ni ubuhe bwoko bw'icyayi gikoreshwa neza? Hano hepfo ni intangiriro yubwoko bwimifuka yicyayi.
1. Umufuka wicyayi wibigori
Fibre yibigori ni fibre synthique ikozwe mubigori, ingano nizindi njangwe nkibikoresho fatizo, bigizwe byumwihariko muri acide lactique hanyuma bigahinduka polymerize hanyuma bikazunguruka. Ni fibre irangiza kuzenguruka bisanzwe kandi irashobora kubora. Fibre ntabwo ikoresha peteroli nibindi bikoresho fatizo bya shimi na gato, kandi imyanda yayo irashobora kubora mo dioxyde de carbone n’amazi bitewe n’ibinyabuzima bito mu butaka n’amazi yo mu nyanja, kandi ntibizanduza ibidukikije ku isi.
2. Umuduka wicyayi pp
Ibikoresho bya pp ni polypropilene, ikaba idafite amashanyarazi, impumuro nziza, kandi idafite uburyohe bwamata yera yera cyane ya polymer. PP polyester ni ubwoko bwa amorphous, aho gushonga bigomba kuba hejuru ya 220, naho ubushyuhe bwacyo bugomba kuba bugera kuri dogere 121. Ariko kubera ko ari macromolecular polymer nyuma ya byose, hejuru yubushyuhe, niko isesengura rito
Birashoboka cyane ko oligomers, kandi ibyinshi muribi ntabwo ari byiza kubuzima bwabantu. Byongeye kandi, ukurikije imikoreshereze yabakiriya, amazi abira muri rusange ni dogere 100, bityo ibikombe rusange bya pulasitike ntibizarangwa na dogere zirenga 100.
3. Umufuka wicyayi wibikoresho byamatungo
Nkibikoresho byo gupakira, PET ifite ubukana buhanitse kandi buke. Irashobora gukoreshwa igihe kirekire mubushuhe bwa dogere 120, kandi irashobora kwihanganira ubushyuhe bwo hejuru bwa dogere 150 kugirango ikoreshwe mugihe gito. Imyuka ya gaze n'umwuka w'amazi ni muke, kandi ifite gaze nziza, amazi, amavuta hamwe no kurwanya impumuro idasanzwe. Gukorera mu mucyo mwinshi hamwe nuburabyo bwiza. Ntabwo ari uburozi, uburyohe, kandi bufite isuku numutekano, kandi birashobora gukoreshwa mubiribwa.
4. Imifuka yicyayi ikozwe mu mpapuro
Usibye impapuro zo kuyungurura zikoreshwa muri laboratoire rusange, hariho byinshi byo gukoresha impapuro zungurura mubuzima bwa buri munsi, kandi impapuro zungurura ikawa nimwe murimwe. Akayunguruzo kurupapuro rwinyuma rwumufuka wicyayi rutanga ubworoherane nimbaraga nyinshi. Impapuro nyinshi zo muyungurura zikozwe muri fibre ya pamba, kandi hariho imyobo mito itabarika hejuru yacyo kugirango ibice byamazi byanyuze, mugihe ibice binini bikomeye bitavuzwe.
5. Impapuro z'icyayi
Kimwe mu bikoresho fatizo bikoreshwa muriyi mpapuro yicyayi ni abaca. Ibi bikoresho biroroshye kandi bifite fibre ndende. Impapuro zakozwe zirakomeye kandi zoroshye, zitanga uburyo bukwiye bwo gukwirakwiza uburyohe bwicyayi. Ibindi bikoresho fatizo ni fibre ya plastike ifunga ubushyuhe, ikora kugirango ushire igikapu cyicyayi. Iyi plastiki ntabwo itangira gushonga kugeza ishyutswe kugeza kuri 160 ° C, ntabwo rero byoroshye gukwirakwiza mumazi. Kugirango wirinde igikapu cyicyayi ubwacyo gushonga mumazi, hongewemo ibikoresho bya gatatu, ibiti byimbaho. Nyuma yo kuvanga abaca na plastike bimaze kuvomerwa, yashizwemo igiti kinini, hanyuma amaherezo ashyirwa mu mashini nini ya metero 40 z'impapuro, hanyuma havuka impapuro z'icyayi.
