Imikorere y'ibikoresho

Ubudahangarwa n'ingese, ubushyuhe bw'amashanyarazi (cyane cyane ubushyuhe bw'amashanyarazi buri hejuru cyane) ni bwiza cyane, bushobora guterwa chlorine, imirasire ihinduka, fibre y'ikirahure irakongerwamo imbaraga. Polyethylene ifite umuvuduko muke ifite aho ishongera cyane, ikomera, ikomeye kandi ifata amazi make, ifite imiterere myiza y'amashanyarazi kandi irwanya imirasire; polyethylene ifite umuvuduko mwinshi ifite ubworoherane bwiza, iramba, imbaraga n'ubushobozi bwo kwinjira; polyethylene ifite uburemere bwinshi bwa molekile ifite imbaraga nyinshi, irwanya umunaniro no kudashira.

Polyethylene ifite umuvuduko muke ikwiriye gukora ibice birwanya ingese n'ibice bikingira ubushyuhe; polyethylene ifite umuvuduko mwinshi ikwiriye gukora filime, nibindi; UHMWPE ikwiriye gukora ibice birwanya impanuka, birwanya kwangirika n'ibikwirakwiza.

Imikorere yo gushushanya

1. Ibikoresho bya kristaline, bikuramo ubushuhe buke, ntibikenera kuma burundu, bivamo amazi menshi, bivamo amazi menshi. Guteramo igitutu kinini birakwiriye mu gushushanya, ubushyuhe bumwe bw'ibikoresho, umuvuduko wo kuzuza vuba no gufata igitutu gihagije. Ntibikwiye gukoresha icyuma gifunga neza kugira ngo hirindwe ko ibintu bigabanuka ku buryo bungana no kwiyongera k'umuvuduko w'imbere. Witondere guhitamo aho irembo riherereye kugira ngo hirindwe ko ibintu bigabanuka cyangwa bihinduka.

2. Ingano y'igabanuka ry'amazi n'agaciro k'igabanuka ry'amazi ni binini, icyerekezo kiragaragara, byoroshye guhindura imiterere y'amazi no kuyahindura uko yakabaye. Umuvuduko wo gukonjesha ugomba kuba muto, kandi ibumba rigomba kugira umwobo ukonje n'uburyo bwo gukonjesha.

3. Igihe cyo gushyushya ntikigomba kuba kirekire cyane, bitabaye ibyo, ibintu bizabora bigashya.

4. Iyo ibice bya pulasitiki byoroshye bifite imiyoboro mito ku ruhande, ifuro rishobora gukurwaho.

5. Gushonga bishobora gucika kandi ntibigomba kuba bihuye n'ibintu bishongesha mu buryo bw'umwimerere kugira ngo bitagwa.

Imiterere y'ibikoresho

Ubucucike buke, imbaraga, ubukana, ubukana no kudashyuha ni byiza kuruta polyethylene ifite umuvuduko muke, ishobora gukoreshwa kuri dogere 100. Imiterere myiza y'amashanyarazi n'ubwirinzi bw'ikirere bwinshi ntibigira ingaruka ku bushyuhe, ariko iracika intege iyo ubushyuhe buri hasi kandi ntirwanya ibishishwa kandi yoroshye gusaza.

Irakwiriye mu gukora ibice rusange bya mekanike, ibice birwanya ingese n'ibice bikingira ubushyuhe.

Imikorere yo gushushanya

1, ibikoresho bikoresha kristalo, ubushobozi bwo kwinjiza amazi ni buke, umubiri ushonga byoroshye gushonga, ibyuma bishyushye bibora igihe kirekire.

2, uburyo bworoshye bwo guhindagurika, ariko uburyo bwo guhindagurika n'uburyo bwo guhindagurika ni binini, byoroshye kugabanuka, gucika intege, no guhinduka.

3. Umuvuduko wihuse wo gukonjesha, sisitemu yo gusukura n'isitemu yo gukonjesha bigomba gutinda kugira ngo ubushyuhe bushire, kandi witondere kugenzura ubushyuhe bwo gushushanya. Icyerekezo cy'ubushyuhe buke bw'ibikoresho kiragaragara, cyane cyane iyo ubushyuhe buke n'umuvuduko mwinshi. Iyo ubushyuhe bw'ibimera buri munsi ya dogere 50, ibice bya pulasitiki ntibiba byoroshye, byoroshye gukora ihurizo ribi, bigasiga ibimenyetso, kandi hejuru ya dogere 90, byoroshye kugorama no guhindura isura.

4, ubugari bw'urukuta rwa pulasitiki bugomba kuba bumwe, wirinde kubura kole, inguni zityaye, kugira ngo hirindwe koroherwa n'imihangayiko.

Imikorere y'ibikoresho

Ubwishingizi bw'amashanyarazi (cyane cyane ubushyuhe bwinshi) ni bwiza cyane, nta ibara kandi bubonerana, igipimo cyo kohereza urumuri ni icya kabiri nyuma y'ibirahure bya organic, irangi, ubushobozi bwo kwirinda amazi, ubushobozi bwo guhagarara neza mu binyabutabire ni bwiza. Ingufu rusange, ariko ziroroshye, zoroshye gutanga stress ziroroha, ntizirwanya benzene, lisansi n'ibindi bintu bishongesha organic.

Irakwiriye gukora ibice bikingira kandi bibonerana, ibice by'imitako n'ibice by'ibikoresho bya chimique n'ibikoresho by'urumuri.

Gutegura imikorere

1, ibikoresho bidafite isura, bikuramo ubushuhe buke, ntibikeneye kuma neza, ntabwo byoroshye kubora, ariko ingano y'ubushyuhe ni nini, byoroshye gutera imbaraga imbere. Ingufu nziza zo gutemba, irahari kugira ngo ikoreshwe mu gucuranga imashini cyangwa gucuranga.

2. Ubushyuhe bwinshi bw'ibikoresho, ubushyuhe bwinshi bw'ibihumyo n'umuvuduko muke wo gutera ni byiza. Kongera igihe cyo gutera ni ingirakamaro mu kugabanya umuvuduko w'imbere no gukumira guhindagurika no kwangirika.

3, iboneka mu buryo butandukanye bwo guhuza irembo, irembo n'inkingi ya pulasitiki, kugira ngo hirindwe kwangirika kw'ibice bya pulasitiki iyo ugiye ku irembo. Ubuso bw'aho imashini ijya ni bunini, aho isohoka ni heza, ubugari bw'urukuta rw'igice cya pulasitiki ni burangana, ni byiza kutagira ibikoresho byo gushyiramo, niba hari ibikoresho byo gushyiramo, bigomba gushyuha.
