Umuyoboro w'amazi ashyushye n'akonje wa PB
Intangiriro y'Umuyoboro w'amazi ashyushye n'akonje wa PB
Umuyoboro wa Polybutene (PB) ni polymer ifite molekile nyinshi idafite molekile. Resine ya PB ni polymer ikozwe muri butene-1. Ifite ubucucike bwihariye bwa 0.937 g/cm3 crystal, ikaba ari ubwoko butandukanye kandi bworoshye. Ni mu bikoresho by'ikoranabuhanga rigezweho by'ibinyabutabire by'umwimerere. Ifite ubushobozi bwo kurwanya ubushyuhe bwinshi, kuramba, kudahinduka kwa shimi no guhindagurika. Nta buryohe, ntabwo ari uburozi, nta mpumuro, ifite ubushyuhe buri hagati ya -30°C na +100°C, kandi irwanya ubukonje, irwanya ubushyuhe, irwanya igitutu, ntirigwa ingese, ntirikwangiza, kandi imara igihe kirekire (imyaka 50-100). Kandi ifite imiterere yo kudasaza igihe kirekire. Ni kimwe mu bikoresho by'ibinyabutabire bigezweho ku isi. Ikoreshwa cyane mu bihugu byinshi ku isi. Kandi ifite izina rya "zahabu muri pulasitiki".
Imiyoboro y'amazi akonje n'ashyushye yo mu rwego rwo hejuru ya PB (polybutylene) ifite ibikoresho 24 byose hamwe. Igabanyijemo imiterere 4 kuva kuri dnl6 kugeza kuri dn32. Dukurikije uruhererekane rw'imiyoboro, igabanyijemo imiterere itandatu: S10, S8, S6.3, S5, S4 na 3 .2..
Urutonde rw'imiyoboro y'amazi ashyushye n'akonje ya PB
Imyanda ivangwa n’imyanda ikorerwa mu nganda zikora ibikoresho bya semiconductor iratunganywa kandi igasubirwamo mu buryo bujyanye n’uburyo ikorwamo binyuze mu gikoresho cyo gukosora kugira ngo ikore ibintu nka stripping liquid B6-1, stripping liquid C01, na stripping liquid P01. Ibi bicuruzwa bikoreshwa cyane cyane mu gukora paneli zigaragaza kristale y’amazi, circuits za semiconductor n’izindi nzira.
Ibiranga umuyoboro w'amazi ashyushye n'akonje wa PB
1.Ni ibiro byoroshye, byoroshye kandi byoroshye kubaka. Uburemere bw'umuyoboro wa PB ni hafi 1/5 cy'umuyoboro w'icyuma gikozwe mu cyuma. Uroroshye kandi woroshye gutwara. Umwanya muto wo kugonda ni 6D (D: umurambararo w'inyuma w'umuyoboro). Ukoresha umuyoboro ushyushye ushonga cyangwa umuyoboro w'imashini, byoroshye kubaka.
2. Iramba neza, ntabwo irimo uburozi kandi nta kibazo ifite. Kubera uburemere bwayo bwinshi bwa molekile, imiterere yayo ya molekile irahamye. Ntabwo irimo uburozi kandi nta kibazo ifite kandi imara igihe kitari munsi y'imyaka 50 nta mirasire ya ultraviolet.
3.t ifite ubushobozi bwo kwihanganira ubukonje n'ubushyuhe. Nubwo iri kuri -20°C, ishobora gukomeza guhangana n'ubushyuhe buri hasi. Nyuma yo gushonga, umuyoboro usubira mu ishusho yawo ya mbere. Mu gihe cy'ubushyuhe bwa 100°C, ibice byose by'imikorere biracyakomeza kubungabungwa neza.
4. Ifite inkuta z'imiyoboro iraryoshye kandi ntabwo ingana. Ugereranyije n'imiyoboro ya galvanised, ishobora kongera amazi ku kigero cya 30%.
5. Biroroshye gusana. Iyo umuyoboro wa PB utwikiriwe, ntuba ufatanye na beto. Iyo wangiritse, ushobora gusanwa vuba usimbura umuyoboro. Ariko, ni byiza gukoresha uburyo bwo gutwikira (umuyoboro uri mu muyoboro) mu gutwikira imiyoboro ya pulasitiki. Ubwa mbere, twikira umuyoboro wa PB n'umuyoboro wa PVC ufite urukuta rumwe, hanyuma uwutwikirize, kugira ngo ibikorwa byo kubungabunga bizagende neza mu gihe kizaza.
