amakuru

Mu gihe inganda z’inganda ku isi ziharanira imikorere myiza, gukoresha neza ikiguzi, no gutanga ibisubizo bitangiza ibidukikije, urwego rw’ingenzi rw’ibinyabutabire rurimo kuvugurura bucece imiterere y’inganda za polyurethane.Anhydride ya Dimethylthioterephtalike, mu magambo ahinnye nka DMTDA (nimero ya CAS: 106264-79-3), nk'umuti uhindura imikorere y'amazi, uha inganda zo muri Aziya y'Amajyepfo y'Uburasirazuba na Amerika y'Amajyaruguru ubundi buryo bwiza buruta ibikoresho gakondo mu bijyanye n'imikorere.

I. Gusobanura Ibipimo by'Imikorere: Ibyiza by'ingenzi bya DMTDA

DMTDA si ikintu gisimbura gusa, ahubwo ni igisubizo cyongerewe imikorere. Ugereranyije n'umuti usanzwe wo gukangura ibintu bikomeye MOCA, DMTDA yageze ku rwego rwo hejuru mu miterere y'umubiri, koroshya imikorere, ndetse n'imikorere y'umusaruro wa nyuma.

Ibisobanuro by'ingenzi bya tekiniki:

Izina ry'igicuruzwa: Dimethyl Thio-Toluene Diamine (DMTDA)
Nimero ya CAS:106264-79-3
Formula ya Molecular:C9H14N2S2
Ishusho:Ikinyobwa cy'umuhondo ubonerana gikozwe mu mazi
Ubwiza:≥95% (Ibikubiye muri Amine yose)
Imikorere:Umuyoboro wo kongeramo imiyoboro / Umukozi wo kuvura / Crosslinker

Imiterere ya chimique ya DMTDA ituma ikora nk'urukiramende rukora neza, rutanga imiterere idasanzwe ya mekanike ku gicuruzwa cya nyuma cya polymer. Imiterere yayo y'amazi ikuraho gukenera gushyushya cyangwa gushonga mbere yo kuyikoresha, ibi bikaba ari ikintu gisanzwe gisabwa ku bikoresho bikomeye nka MOCA, bityo bikagabanya ingufu no kunoza umutekano w'aho bakorera.

II. Kuki wahitamo DMTDA? Ihinduka ryavuye muri MOCA

Gukora byoroshye, imikorere yikubye kabiri

Amavuta ku bushyuhe bw'icyumba: DMTDA igaragara nk'amazi y'umuhondo werurutse afite viscous ku bushyuhe bw'icyumba, bikuraho gukenera uburyo bugoye bwo gushonga nka MOCA. Ibi ntibigabanya gusa ishoramari ry'ingufu n'ibikoresho ahubwo binaroroshya inzira yo gukora, bikongera cyane imikorere myiza y'umusaruro.

Kuvanga byoroshye kandi bitoroshye: Kuvanga byoroshye bituma bivangwa vuba kandi bingana na prepolymer, cyane cyane bikwiranye n'ibikorwa bigezweho nko gusya no gutera imiti ya polyurea elastomers bisaba imikorere myiza yo kuvanga.

Ubukungu bwiza cyane, inyungu nini ku giciro

Igipimo gito: Ingano y'ibinyabutabire ya DMTDA iri hasi ugereranyije n'iya MOCA, bigatuma ikoreshwa ry'ibikoresho rigabanukaho 20% mu bikorwa bifatika. Ibi bivuze kugera ku musaruro umwe cyangwa mwiza kurushaho mu gihe bigabanya ikiguzi cy'ibikoresho fatizo.

Igiciro gihoraho: Kubera inzira z'umusaruro zigezweho n'ingaruka zabyo ku gipimo,igiciro cya DMTDAikomeje guhindagurika, itanga garanti yizewe yo kugenzura ibiciro by'igihe kirekire ku bigo.

Ubwiza burushijeho kuba bwiza: Imiterere myiza y’umubiri: Elastomer ya polyurethane yavuwe na DMTDA irusha sisitemu ya MOCA mu bimenyetso by’ingenzi nko kwihanganira, kudashira, no kudacikagurika. Ibi bituma umusaruro wa nyuma uramba kandi ukabasha kwihanganira ibintu bigoye cyane.

Ikoreshwa cyane: Kuva ku byuma bipima neza, ibice by'imodoka, kugeza ku bikoresho bikingira umuriro, ibikoresho by'icyuma birwanya ingese, uburyo DMTDA ikoresha buri gihe bukomeza kwaguka, bigatanga imbaraga zikomeye mu kuvugurura ibicuruzwa mu nganda zitandukanye.

Bitekanye kandi bitangiza ibidukikije, bikurikiza uko ibintu bigenda ku isi

Uburozi buke, bufite umutekano: Uburozi bwaDMTDAiri hasi cyane ugereranyije n’iya MOCA, kandi nta ngaruka zitera kanseri cyangwa impinduka mu mikorere yayo, binoza cyane ibidukikije by’umusaruro kandi bikizeza ubuzima bw’abakora, bigatuma ibigo byubahiriza byoroshye amabwiriza akomeye y’ubuzima n’umutekano mu kazi.

III. Uburyo bworohereza ibidukikije

Uburyo bwo kuyitunganya bukoresha uburyo buhendutse kandi butangiza ibidukikije bwo “gutunganya ibikomoka ku bimera bidafite aho bibogamiye”, bukurikije icyerekezo cy’isi yose cyo gukora ibikomoka ku bimera bidafite aho bibogamiye.

Gushishikarira cyane Aziya y'Amajyepfo y'Uburasirazuba na Amerika ya Ruguru: Isoko ryiyongera cyane

Nubwo intambwe z’iterambere ry’amasoko yo muri Aziya y’Amajyepfo y’Uburasirazuba na Amerika y’Amajyaruguru zitandukanye, zombi zifite icyifuzo cyihutirwa cyo gushaka ibisubizo by’ibikoresho bigezweho kandi binoze.

Isoko rya Aziya y'Amajyepfo y'Uburasirazuba: Ibikorwaremezo n'inganda byazamutse

Urusobe rw'inyubako zirinda ibidukikije: Bitewe n'umuvuduko w'imijyi mu bihugu byo muri Aziya y'Amajyepfo y'uburasirazuba, icyifuzo cy'ibikoresho by'ubwubatsi bifite imikorere myiza cyariyongereye cyane. Ikoreshwa rya DMTDA mu mavuta akingira umuriro n'ibyuma birwanya ingese byujuje neza amahame yo hejuru y'umutekano w'inyubako no kuramba bisabwa n'iri soko.

IV. Kuvugurura inganda

Nk’ingenzi mu iterambere ry’inganda ku isi, inganda zikora imodoka, imyenda, n’impapuro zo muri Aziya y’Amajyepfo y’uburasirazuba zirimo gutera imbere vuba. Gukoresha DMTDA mu nganda zikora ibikoresho byo mu rwego rwo hejuru nk’ibice by’imodoka n’imashini zicapa bishobora gufasha ibigo byo mu gace k’iwabo kunoza ipiganwa ry’ibicuruzwa no gufata uruhererekane rw’agaciro rwo mu rwego rwo hejuru.

Isoko rya Amerika y'Amajyaruguru: Udushya mu ikoranabuhanga n'inganda zigezweho

Igitera imbaraga mu mikorere iteye imbere: Isoko rya Amerika y'Amajyaruguru ni irya mbere mu ikoranabuhanga riteye imbere nko gusya inshinge no gutera imiti ya polyurea elastomers. Nk'umuti mwiza wo kuvura amazi,DMTDAishobora gukoresha neza inyungu z'izi nzira no guteza imbere udushya mu ikoranabuhanga mu bice nko gusiga urumuri rw'imodoka no gukingira imodoka mu buryo bworoshye.
