Polyurethane Vulcanizing Agent Kubikorwa Byinganda

Ibikoresho bya polyurethane, bizwi kandi nka polyurethane rubber cyangwa polyurethane elastomer, ni umuryango wibikoresho bya elastomeric bifite uburyo bwinshi bwo gukoresha. Rubber ya polyurethane ikubiyemo amatsinda atandukanye ya chimique kumurongo wa polymer, harimo amatsinda ya urethane, amatsinda ya ester, amatsinda ya ether, amatsinda ya urea, amatsinda ya aryl, n'iminyururu ya alifatique, kandi ifite uburyo bwinshi bwo gukoresha no gukora.

Gukora reberi ya polyurethane ikubiyemo reaction ya oligomeric polyol, polyisocyanates hamwe niyagura urunigi. Binyuze mu bikoresho fatizo n’ibipimo bitandukanye, uburyo bwo kubyitwaramo nuburyo ibintu bimeze, reberi irashobora guhindurwa kugirango ibe imiterere nuburyo butandukanye kugirango ihuze ibikenewe.

Ikoreshwa

Bumwe mu buryo bugaragara bwa reberi ya polyurethane ni mu gukora ibiziga bya polyurethane ku makamyo ya pallet. Yashizweho kugirango ikoreshwe-imirimo iremereye, izi nziga zitanga uburebure budasanzwe nubushobozi bwo gutwara imizigo. Amapine ya polyurethane akoreshwa kuri caster na pedal ya pedal atanga uburyo bwiza bwo gukwega no guhungabana kugirango byorohe, byoroshye.

Ikindi kintu cyingenzi gikoreshwa ni ibikoresho bya mashini. Amasoko ya polyurethane nubundi buryo bwizewe kumuzingo gakondo kandi bitanga uburyo bwiza bwo kwambara. Ibi bituma biba byiza mubikorwa bisaba guhora bigenda no gukoresha imashini ziremereye.

Ku bakora ibiziga bya scooter, reberi ya polyurethane nibikoresho byo guhitamo. Hamwe na kamere yayo itandukanye, itanga imikorere myiza, kuramba no kugenda neza.

Byongeye kandi, reberi ya polyurethane ikoreshwa cyane mu nganda zikoreshwa mu miti itanga ibicuruzwa bitarinda amazi nka PU track and track track, igisenge cya PU, igipfundikizo cya PU, hamwe n’ibikoresho bitarimo amazi. Imiterere yihariye ya reberi ya polyurethane, harimo kurwanya amazi, imiti n’imirasire ya UV, bituma ihitamo igihe kirekire kuriyi porogaramu.

Mu gusoza, reberi ya polyurethane ni ibintu byinshi kandi byizewe bya elastomeric ikora muburyo butandukanye mubikorwa bitandukanye. Ibintu byihariye bidasanzwe, nko kuramba, kwihangana no kurwanya abrasion, bituma biba byiza kubakora nubucuruzi bashaka ibisubizo bihanitse. Yaba ibiziga by'amakamyo ya pallet, ibice by'imashini, ibiziga bya scooter cyangwa ibishishwa bitarinda amazi, reberi ya polyurethane ikomeje kwerekana agaciro kayo nkibikoresho byingenzi ku isoko muri iki gihe. Wizere imikorere ya reberi ya polyurethane kandi wibonere imikorere yongerewe igihe kirekire nibicuruzwa byawe.
