Mu bihe nko gutwara ibikoresho bya mashini, gucunga ibikoresho byo gufotora, no guhindura ububiko, ibikoresho byo gukata ntibigomba gusa kuba bishobora kwihanganira uburemere, ahubwo bigomba no kuzirikana uburyo bwo kwirinda kwangirika, ituze, kugenda neza, n'igihe cyo kubikoresha. Impamvu nyamukuru ituma ibikoresho byo gukata bitambitse bya polyurethane bikoreshwa cyane ni uko bihuza imiterere y'ibikoresho n'imiterere y'inyubako mu buryo buringaniye. Muri make, bishobora gutuma igikoresho kigenda neza kandi bigakomeza gukora neza mu bintu byinshi bigoye.
1. Imiterere myiza y'ibikoresho, kuringaniza ubushobozi bwo kudashira, kugabanya urusaku, no kwihanganira imizigo
Polyurethane, izwi kandi nka PU, ni ibikoresho bya polymer bikoreshwa cyane. Akamaro kayo kari mu mikorere yayo minini ishobora guhindurwa, ishobora koroshya kugira ngo yongere ingaruka zo kugabanya urusaku no kongera ubushobozi bwo kwihanganira kwangirika.
Ugereranyije na rubber isanzwe, polyurethane irashaje cyane kandi ntikunda kwangirika vuba bitewe no kuzunguruka igihe kirekire; Ugereranyije n'amapine ya nylon, ifite ubushobozi bworoshye bwo guhindagurika, ikagira ingaruka nke ku butaka iyo igenda, kandi ikagira urusaku ruto. Kubera iyo mpamvu, polyurethane casters ikunze gukoreshwa ahantu hakorerwa imirimo hasaba uburinzi ku butaka no kugenzura urusaku.
Mu miterere, ubu bwoko bwa caster bukoresha icyuma gikozwe mu cyuma gihujwe n'icyuma gitwikiriye polyurethane. Icyuma gikozwe mu cyuma gitanga imbaraga zo gushyigikira, mu gihe icyuma cyo hanze cya polyurethane gikorana n'ubutaka kandi kikaba gishinzwe gufata impanuka, kugabanya urusaku, no kudashira. Nyuma yo guhuza ibyo byombi, ubushobozi rusange bwo kwihanganira imizigo no kudashira kw'ibice bitwikiriye bizaba byiza kurushaho.
2. Ingaruka nziza zo guceceka, zikwiriye ahantu hakenewe ibidukikije byinshi
Akamaro kamwe gakomeye k’ibikoresho bya polyurethane bidacecetse ni urusaku ruto mu gihe cyo gukora. Impamvu si igoye: polyurethane ubwayo ifite urwego runaka rwo kwihuta, ishobora gukurura bimwe mu bintu biva ku butaka iyo amapine azunguruka, bigagabanya guhinda no guhindagurika kw’urusaku guterwa no kugongana gukomeye.
Ku mapine asanzwe akomeye, icyuho gito cyangwa ubusumbane ku butaka bishobora gutera amajwi agaragara yo kuzenguruka iyo bigiye; Amapine ya polyurethane, bitewe nuko yoroshye gukoranaho no kugenda neza, akunze gutanga urusaku ruto mu gihe cy'imizigo imwe.
Ubu bwoko bw'iyi mikorere bukwiriye cyane cyane ahantu hasaba ituze, nko gufata ibikoresho byo gufotora, kugenda kw'ibikoresho byo kugerageza, gutwara ibikoresho mu nzu, hamwe n'ahantu hamwe na hamwe hakorerwa ibintu hasaba ahantu ho gukorera. Iyi mikoreshereze iba ituje cyane iyo igenda kandi ifasha kugabanya ingaruka z'ihindagurika ry'imikoreshereze ku bikoresho ubwabyo.
3. Imiterere y'icyerekezo ituma umurongo ugororotse urushaho kugenda neza
Uretse ibyiza by'ibikoresho ubwabyo, imiterere y'icyerekezo nayo ni ingenzi muri ubwo bwoko bwa caster. Icyo bita uruziga rw'icyerekezo bivuga uruziga rushobora kugenda imbere gusa mu cyerekezo gihamye kandi rudashobora kuzunguruka nk'uruziga rw'isi yose.
Akamaro k'iyi nyubako ni uko igenda neza mu murongo ugororotse, cyane cyane ikwiriye ibintu nko gutwara imizigo idahinduka, gusunika ibikoresho imbere n'inyuma, ndetse no kugendana n'imirongo ikora. Iyi nyubako ntikunda guhindagurika cyane mu gihe cyo kugenda kandi biroroshye kuyigenzura mu gihe ikora.
Niba ahantu hakoreshwa ahanini hakubiyemo kugenda mu nzira yagenwe mbere, nko mu miyoboro y’imodoka, imiyoboro y’ibikoresho biremereye, uburyo bwo gufata amashusho bufashijwe n’inzira, ibikoresho biyobora icyerekezo akenshi birakwiriye kuruta ibikoresho bizunguruka. Nubwo ubushobozi bwo koroha butari hejuru nk’ubw’amapine asanzwe, bufite inyungu nyinshi mu gutuza no kugenzura icyerekezo.
4. Kurwanya ubushyuhe bwinshi, kurwanya hydrolysis, kurwanya peteroli, no guhangana n'ibidukikije bikomeye
Ibisabwa ku bikoresho byo gukata mu nganda akenshi ntibikubiyemo kugenda gusa, ahubwo binakubiyemo no kwihuza n’ibidukikije bigoye. Ibikoresho byo gukata bitambitse bya polyurethane nabyo bifite inyungu zikomeye muri urwo rwego.
Ubwa mbere, ifite ubushobozi bwo kwangirika neza kandi ntishobora kwangirika cyane cyangwa kwangirika vuba nyuma yo gukoreshwa igihe kirekire. Ubwa kabiri, ifite ubushobozi bwo kwihutisha ibidukikije bitose, ibidukikije bikoresha amazi, ndetse n'ahantu hahumanya peteroli, bigatuma ikunze gukoreshwa mu gutwara ibintu mu buryo bwa mashini, mu bubiko, mu mashami, no mu bindi bihe.
Ibikoresho bya polyurethane byahinduwe igice nabyo bifite ubushobozi bwo guhangana n'ubushyuhe kandi bishobora kwihuza n'ahantu hakorerwa ubushyuhe mu rugero runaka. Ibi ni ingirakamaro cyane mu matsinda amwe n'amwe y'ubushyuhe bwinshi cyangwa mu bihe byo gukoresha hamwe n'aho ubushyuhe buhurira n'igihe gito.
5. Mu gihe uhitamo, shyira imbaraga kuri ibi bipimo bitatu
Reba ubushobozi bwo gutwara. Mu guhitamo amapine, ntibihagije kureba gusa imiterere n'ingano y'amapine, ahubwo ikiruta byose, kureba niba umutwaro w'ipine rimwe ushobora kuzuza uburemere bwose bw'ibikoresho. Akenshi ni byiza gusiga ingano runaka hashingiwe ku buremere nyabwo, butekanye kandi buramba.
Icya kabiri, reba umurambararo w'uruziga n'ubugari bw'urusobe rw'uruziga. Uko umurambararo w'uruziga uba munini, niko byoroha gusunika kandi niko birushaho kuba byiza; Ariko niba umwanya wo gushyiraho ari muto, hagomba kuba uburinganire hagati y'ingano n'ibisabwa mu gukoresha.
Icya gatatu, genzura ubukana. Ubukana bwinshi, akenshi burwanya kwangirika no kwihanganira imitwaro; Ubukana buke buzatuma habaho uburyo bwiza bwo gufunga no kugabanya urusaku. Niba ubutaka butaringaniye bihagije, formula ya polyurethane ifite ubukana bwiza ishobora gushyirwa imbere.
6. Ni izihe nyungu zabyo ugereranije n'abakoresha basanzwe?
Ugereranyije n'amapine asanzwe ya rubber, amapine ya polyurethane asanzwe afite ubushobozi bwo kudashira neza kandi amara igihe kirekire. Ugereranyije n'amapine ya nylon, akora neza mu bijyanye no kugabanya urusaku, gufata impanuka no kurinda ubutaka.
Byongeye kandi, itandukaniro riri hagati y’amapine y’icyerekezo n’amapine y’isi yose rigomba gutandukanywa. Amapine y’isi yose yoroshye kandi akwiriye ibintu bisaba guhindurirwa kenshi; Amapine y’icyerekezo akwiriye cyane mu bihe aho imirongo igororotse, ituze, no kugenzura inzira ari ingenzi. Ku bikorwa byinshi byo gutwara no gukoresha ibikoresho mu nganda, amapine y’icyerekezo mu by’ukuri akora neza kurushaho.
Umwanzuro
Muri rusange, ibyiza bya tekiniki bya polyurethane buceceke bigaragarira ahanini mu bintu bine: imiterere y’ibikoresho iringaniye, imikorere ituje, kugenda neza mu murongo, no kwihuza neza n’ibidukikije. Ku bikoresho bikeneye kuringaniza uburyo bwo gutwara imizigo, kudasaza, guceceka no kugenzura icyerekezo, ni amahitamo afatika.
Mu kugura ibikoresho nyabyo, birasabwa guhitamo ibikoresho hashingiwe ku buremere bwabyo, imiterere y'ubutaka, inzira binyuramo, n'inshuro bikoreshwa. Guhitamo amapine akwiye ntibishobora kongera imikorere y'ibikoresho gusa, ahubwo binagabanya ikiguzi cyo kubisana no kubisimbuza mu gihe kiri imbere.
