Hanze ya PE igizwe numuyoboro wa pulasitike
Hanze ya PE igizwe numuyoboro wa pulasitike, Umuyoboro wa pulasitike ushyizwe hamwe (uzungurutswe) umuyoboro wibyuma udafite umurambararo wa diametre, ubunini bwurwego rushobora no gutoranywa uko bishakiye, ukurikije imiterere yo hagati ya ruswa, hitamo uburebure butandukanye, uburebure bushobora no kugera kuri 6-12 metero;Umurambararo umwe wizina, ushyizwemo (uzungurutswe) plastike igizwe nicyuma gisanzwe kiri hagati ya 0.5-1mm, hejuru yigituba cyoroshye, ntabwo coefficente yo guterana gusa ari nto, kandi coefficient de friction nayo ni nto, gutakaza amazi mumazi ni bito, gutembera ni binini, kugirango ugere ku kuzigama ingufu.Mu myaka yashize, imiyoboro irwanya ruswa ikoreshwa cyane mukubaka amazi nogutwara amazi, imiyoboro yo gukwirakwiza amazi yo kunywa, kugenzura umuriro, kumuyoboro wibyuma byumuriro cyane mbere yo gukoresha umuyoboro wibyuma ushyushye, abaturage benshi, amahoteri, inyubako zo mu biro ubu zirimo gukoresha epoxy powder anticorrosive umuyoboro wibyuma impande zombi zometseho plastike ikoreshwa haba imbere ndetse no hanze nkibikoresho byumuriro wumuriro, isura nziza kandi iramba, Yabaye ibicuruzwa byingenzi byinganda zivuka mukinyejana cya 21.PE imbere muri EP yatwikiriye ibyuma bya pulasitiki ibyuma byumwuga kugurisha ifu isize ibyuma bya pulasitike byongeweho flame retardant hamwe nifu ya epoxy resin ifu ihindagurika, ubushyuhe bwubushyuhe bwa coating burarenze, mugukoresha igihe kirekire ntabwo bwaka, ntibworoshye.
Hanze ya Pe Igizwe na Plastike Umuyoboro, Ibyiza
Filime irangi ya epoxy powder anticorrosive ibyuma birakaze, birwanya amazi kandi ntabwo ari uburozi.Gukomera cyane, gufatana neza hagati ya firime irangi na firime.Kurwanya cyane ingese no kurwanya amazi, gukoresha ibikoresho byiza birwanya ingese, kugirango bikore neza.Ifite imbaraga zubukanishi, firime ikomeye, kurwanya abrasion no kurwanya ingaruka.Ibirimo bikomeye, firime yuzuye.Imiterere ya molekuline ya porojeri ya epoxy anticorrosive umuyoboro wicyuma irangwa nitsinda ryimikorere ya epoxy mumurongo wa molekile, rishobora kuba kumpera, hagati cyangwa impeta yumurongo wa molekile.
Kuberako amatsinda akora epoxy mumikorere ya molekile, barashobora guhuza nubwoko butandukanye bwo gukiza kugirango bakore polymer zidashobora gukemuka kandi zidashobora gukoreshwa hamwe ninzira eshatu.Ifu ya Thermosetting ifu ikoreshwa cyane cyane mubihugu bitandukanye: ifu ya epoxy yifu, ifu ya epoxy fenolike, ifu ya polyester, ifu ya epoxy-polyester.Muri byo, ifu ya epoxy itwikiriye ni uburyo bwambere bwo kuyikoresha, ni nabwo umusaruro wubu wo gutwika ifu ya pulasitike, ukoreshwa cyane mugikorwa cyo gutera imiti ya electrostatike, mubitaka bishushanya bigira umwanya wingenzi;Kubera imiti myinshi irwanya ruswa, epoxy fenolike ifu ikoreshwa cyane mukurwanya ruswa.
Ifu ya Thermoplastique Ifu Yibanze
Ifu ya polyethylene, ifu ya POLYvinyl ya chloride, ifu ya polypropilene, ifu ya chlorine polyether ifu, ifu ya nylon, ifu ya polifhenelene sulfide ifata ifu, nibindi, ibi bikoresho byifu ya thermoplastique bifite ibyiza nibibi.Amashanyarazi ya Thermosetting afite uburyo bwiza bwo gukiza kuringaniza no guhindagurika kubera uburemere buke bwa molekile, ibyo bigatuma bifatana cyane kumubiri wigituba mugihe utwikiriye umuyoboro wibyuma, kandi birashobora gutuma umuyoboro wicyuma usize ubona hejuru ya firime ya plastike neza.Ibisanzwe bikoreshwa muri plastiki ya thermosetting ni: epoxy resin, resin fenolike, amino resin nibindi.Ubunini bwurukuta rutwikiriye buri hagati ya microne 100 na micron 500, mubisanzwe microne 350.
Hanze ya PE ikomatanya umuyoboro wa pulasitike, 1. Ubuzima, butarimo uburozi, nta gupima, nta korora mikorobe, kwemeza ubwiza bwamazi 2. 3. Igikorwa cyo kwishyiriraho kirakuze, cyoroshye kandi cyihuse, kandi guhuza numuyoboro usanzwe wa galvanis ni kimwe.4. Kurwanya ikirere cyiza.5. Urukuta rw'imiyoboro yoroshye, kunoza uburyo bwo gutanga amakuru, igihe kirekire cyo gukora.
Hanze ya PE igizwe numuyoboro wa pulasitike, uburyo bwo guhuza:guhuza urudodo: koresha intoki zipfunyika insinga cyangwa imashini y'amashanyarazi kugirango utunganyirize umugozi, witondere gukonja mugihe cyo gutunganya;Ihuza rya flange, gupima kurubuga, gushushanya umuyoboro umwe ikarita yo gutunganya umurongo, gutunganya ibicuruzwa, gutondekanya plastike, hanyuma bikajyanwa mububiko;Umuyoboro wa pulasitike udashyizwe hamwe, ushyizwe ku murongo hamwe n’ibikoresho byo mu miyoboro birashobora gukoreshwa mu murima, gusudira flange, guteranya imiyoboro, hanyuma ugasenywa kugira ngo ubitwikire, bitunganyirizwe ku murongo wa pulasitike, hanyuma bijyanwe aho byashyizwe;Ibikoresho bya pulasitiki byuzuye byuzuye bigomba guhitamo;Amashanyarazi agomba gukanda n'imashini izunguruka, kandi ibishishwa bigomba gukurikiza ibipimo bijyanye.
