Uburyo bwo kunoza ikwirakwira ry'ibintu bigabanya umuriro

Bitewe n'ikoreshwa ryagutse ry'ibikoresho bya polymer n'ibikoresho by'ikoranabuhanga mu buzima bwa buri munsi, inkongi nazo zikomeje kwiyongera, kandi ingaruka mbi zitera zirushaho gutera ubwoba. Imikorere y'ibikoresho bya polymer igabanya inkongi z'umuriro yarushijeho kuba ingenzi, ni ukugira ngo hagerwe ku bisabwa na pulasitiki n'ibicuruzwa bya kabutike, kugabanya umwanda w'umukungugu uterwa n'ibicuruzwa bigabanya inkongi z'umuriro, masterbatch igabanya inkongi z'umuriro yavutse, kandi igira uruhare runini mu kubumba ibicuruzwa bya nyuma.

Itsinda ry’ibikoresho bigabanya umuriro rikorwa hakurikijwe uburyo bukwiye, binyuze mu guhuza ibikoresho bigabanya umuriro, ibikoresho bigabanya amavuta n’ibikoresho bitwara umuriro, binyuze mu gutunganya cyane, kuvanga, guhuza hanyuma bigasohoka. Muri ibi, ibikoresho bigabanya umuriro bigira uruhare runini cyane, kongeramo igice runaka cy’ibikoresho bigabanya umuriro bishobora kuba byiza cyane mu guteza imbere uburyo ibintu bigabanya umuriro bikwirakwira, bityo bikaba byoroshye gukwirakwira mu buryo bungana muri icyo gikorwa, kugira ngo hirindwe ko ibintu bigabanya umuriro bitera kwiyongera, uko bigabanya umuriro birushaho kuba byiza, kugira ngo ibintu bigabanya umuriro bigire ingaruka nziza ku buryo ibintu bigabanya umuriro birushaho kuba byiza, bityo bikanoza imikorere y’ibikoresho bigabanya umuriro bya pulasitiki, ibikoresho bya kabutike, umuriro uzahagarikwa mu ntangiriro.

Ariko, mu by’ukuri, plastiki nyinshi n’ibice bya kabutura birimo ibice bigabanya umuriro ntibishobora gukora neza bitewe n’uko ibigabanya umuriro bitangana mu bikoresho mu muriro, bigatera inkongi nini n’igihombo gikomeye.

Kugira ngo habeho gukwirakwira kw'ibintu bigabanya umuriro cyangwa masterbatch igabanya umuriro mu buryo bumwe mu gutunganya ibicuruzwa, kugabanya gukwirakwira kw'ibintu bigabanya umuriro bitewe n'ingaruka zigabanya umuriro zidashobora gukoreshwa neza, n'ibindi, no kunoza ubwiza bw'ibintu bigabanya umuriro, SILIKE yakoze SILIMER hyperdispersant yahinduwe.

SILIMER ni ubwoko bwa siloxane yahinduwe ya copolymerized tri-block igizwe na polysiloxanes, amatsinda ya polar na matsinda y'iminyururu miremire ya karuboni. Ibice by'iminyururu ya polysiloxane bishobora kugira uruhare runaka hagati ya molekile zigabanya umuriro munsi y'uburyo bwa mechanical shear, bikabuza ko molekile zigabanya umuriro ziyongera; ibice by'iminyururu bifite aho bihurira n'umunyururu ugabanya umuriro, bikagira uruhare rwo guhuza; ibice by'iminyururu miremire ya karuboni bifite aho bihurira neza n'ibikoresho by'ibanze.

Uru ruhererekane rw'ibicuruzwa rukwiriye resins zisanzwe za thermoplastic, TPE, TPU n'izindi elastomers za thermoplastic, kandi rushobora kunoza imikoranire hagati y'amabara/ifu yuzuza/ifu ikora neza na sisitemu za resins, kandi rugakomeza imiterere y'ifu ikwirakwira neza.

Muri icyo gihe, bishobora kandi kugabanya ubukana bw'ingufu zishongeshwa, kugabanya imbaraga z'ingufu zishongeshwa, umuvuduko w'ingufu zishongeshwa, kunoza imikorere y'ibikoresho, hamwe n'amavuta meza yo gutunganya, kandi icyarimwe bishobora kunoza neza imiterere y'ubuso bw'ibikoresho, hamwe n'uburyo runaka bworoshye kandi ntibigire ingaruka ku miterere y'ibikoresho, ni uguteza imbere ikwirakwira ry'ibice bishongeshwa n'umuriro kugira ngo biteze imbere ingaruka zishongeshwa n'umuriro z'umusaruro wa nyuma kugira ngo bitange umusaruro mwiza.

Byongeye kandi, uru ruhererekane rw'ibicuruzwa ntirukwiriye gusa kuri masterbatch igabanya umuriro, ahubwo rukwiriye no kuri masterbatch y'amabara cyangwa ibikoresho byashyizwemo ibintu byinshi mbere yo gutatanya.
