Umucyo Duty Rigid Caster (PP, PU, ​​PVC) EB3 Urukurikirane-Urudodo rwibiti (Chrome plaque)

Ibyuma bya polyurethane yibyuma bikozwe muri polyurethane, bifatanye kugirango baterwe ibyuma cyangwa ibyuma cyangwa ibyuma.Biratuje, bitinda kandi byubukungu, kandi birashobora gukoreshwa henshi mubidukikije.Nyamara, ibyuma byibanze bya polyurethane ntabwo byuzuye.

Ibikoresho bya polyurethane bifite ubushobozi bwo kwikorera imitwaro, kurwanya neza kwambara, kurwanya ruswa, no gukora neza birwanya vibrasiya, bishobora gufatwa nkuguhitamo kwambere ibikoresho bya caster.Mubihe bisanzwe, ubunini bwinganda ziri hagati ya santimetero 4 na 8 (100-200mm).Ibiziga bya polyurethane nibikoresho byiza, hamwe no kurwanya kwambara neza, uburyo butandukanye bwo guhindura imikorere, uburyo butandukanye bwo gutunganya, gukoreshwa kwinshi, kurwanya amavuta, no kurwanya amavuta.Ozone, kurwanya gusaza, kurwanya imishwarara, kurwanya ubushyuhe buke, kwijwi ryiza neza, gukomera cyane, biocompatibilité nziza hamwe no guhuza amaraso.

1. Imikorere irashobora guhinduka murwego runini.

Umubare wibipimo byimikorere nubukanishi birashobora guhinduka muburyo butandukanye binyuze muguhitamo ibikoresho fatizo no guhindura formulaire, kugirango byuzuze ibisabwa byihariye kubakoresha kugirango bakore ibicuruzwa.Kurugero, gukomera akenshi ni ikimenyetso cyingenzi cyibicuruzwa byabakoresha.Polyurethane elastomers irashobora gukorwa muburyo bworoshye bwo gucapa reberi hamwe na Shore Ubukomezi bugera kuri 20, cyangwa ibyuma bizunguruka byuma byuma bya Shore D bifite uburemere bwa 70 cyangwa burenga.Ibi biragoye kubikoresho rusange bya elastomer, kandi birashobora guhuzwa nibyifuzo byabakoresha batandukanye.Polyurethane elastomer nigikoresho cya polar polymer igizwe nibice byinshi byoroshye kandi bikomeye.Mugihe igipimo cyibice bikaze cyiyongera nubucucike bwamatsinda ya polar yiyongera, imbaraga zumwimerere nubukomere bya elastomer biziyongera bikwiranye.

2. Kurwanya kwambara birenze.

Imbere y'amazi, amavuta nibindi bitangazamakuru bitose, birwanya kwambara kwa polyurethane akenshi usanga inshuro nyinshi kugeza ku nshuro icumi z'ibikoresho bisanzwe.Nubwo ibikoresho byibyuma nkibyuma bigoye cyane, ntabwo byanze bikunze birinda kwambara;ibindi nk'umuceri wo gukuramo umuceri reberi, gutegura amakara yerekana ibinyeganyega, siporo yo gusiganwa ku maguru, hamwe na kashe ya mavuta ya dinamike ya crane forklifts Impeta, ibiziga bya lift, ibiziga bya roller skate, nibindi nabyo niho haza elastomeri ya polyurethane. Ingingo imwe ikeneye kuvugwa hano ni uko kongera coeffisiyoneri yo guteranya ibice bito n'ibiciriritse bikabije bya polyurethane elastomer no kunoza imyambarire yo kwambara munsi yumutwaro, umubare muto wa aluminium disulfide, grafite cyangwa amavuta ya silicone ushobora kongerwaho muri ubu bwoko bwa polyurethane elastomer.Amavuta.

3. Uburyo butandukanye bwo gutunganya nuburyo bukoreshwa.

Polyurethane elastomer irashobora kubumbabumbwa muguhindura plastike, kuvanga, no gutunga ibirunga nka reberi rusange (bivuga MPU);irashobora kandi gukorwa mubibabi byamazi, gutera inshinge compression kubumba cyangwa gutera, kubumba, kubumba centrifugal (bivuga CPU);irashobora kandi gukorwa ibikoresho bya Granular, nka plastiki isanzwe, ibumbabumbwe no guterwa inshinge, gusohora, kalendari, guhumeka hamwe nibindi bikorwa (bivuga CPU).Ibice byabumbwe cyangwa inshinge birashobora kandi gutunganywa mugukata, gusya, gucukura, nibindi murwego runaka.Ubwinshi bwo gutunganya butuma ikoreshwa rya polyurethane elastomers yaguka cyane, kandi imirima yo gusaba ikomeza kwaguka.

4. Kurwanya amavuta, kurwanya ozone, kurwanya gusaza, kurwanya imishwarara, kurwanya ubushyuhe buke, amajwi meza, kwizirika gukomeye, biocompatibilité nziza no guhuza amaraso.Izi nyungu nimpamvu zituma polyurethane elastomers ikoreshwa cyane mubisirikare, mu kirere, acoustics, biologiya no mubindi bice.

Ikibi ni uko ubushyuhe bwimbere ari bunini, imikorere yubushyuhe bwo hejuru ni rusange, cyane cyane ubushuhe nubushyuhe ntabwo ari byiza, kandi ntibishobora kwihanganira imishwarara ikomeye ya polar hamwe na acide ikomeye nibitangazamakuru bya alkali.
