Umuyoboro wa Polyurethane (PU) ukozwe mu buryo bwa pulasitiki (Plastic-Reinforced Spiral Corrugated Hose) ni umuyoboro ugezweho kandi ukoreshwa mu buryo bwinshi, wakozwe kugira ngo uhuze n'ibikenewe cyane mu nganda, ubucuruzi n'ubuhinzi. Imiterere yawo y'ibanze ihuza urukuta rw'imbere rwa PU rworoshye kandi rudashira hamwe n'insinga ya pulasitiki ivanze (cyangwa insinga y'icyuma ikozwe mu muringa yo kuyikwirakwiza mu buryo butaziguye), itanga uburinganire budasanzwe bwo koroha, gukomera no kuramba.
Ubwa mbere, imiterere y'ibikoresho byayo ituma iramba cyane: umuyoboro wa PU (ushingiye kuri polyester) ufite ubukana bwa Shore A bwa 95±2, butanga ubudahangarwa bwiza bwo kwangirika, gucika, no gukomereka—buruta uburyo bwa PVC cyangwa se uburyo bwa PVC inshuro 3-5 mu bihe byo kwangirika cyane (urugero, kwimura ibikoresho nk'isima cyangwa ibinyampeke). Insinga za pulasitiki zigabanya gukenera insinga zikomeye (keretse byavuzwe) mu gihe zigumana ubuziranenge bw'imiterere yazo, bigatuma umuyoboro ubasha kwihanganira igitutu cyiza kugeza kuri bar 10 n'igitutu kibi (gukuramo) cya bar -0.9, bigatuma ikoreshwa mu gutwara ibikoresho no mu buryo bukoresha imashini.
Icya kabiri, itanga uburyo bwo guhangana n’ibidukikije mu buryo bwagutse: ikora neza mu bushyuhe buri hagati ya -40°C na 90°C (ifite ubushobozi bwo kwihanganira ubushyuhe bw’igihe gito kugeza kuri 120°C), ikomeza koroha no mu bukonje bukabije (bitandukanye n’imiyoboro ikomeye ya PVC) kandi irwanya kwangirika mu bidukikije bishyuha cyane. Byongeye kandi, ubwoko bw’ibiribwa (bukurikije amahame ya EU 10/2011 na FDA) nta phthalate, BPA, n’ibyuma biremereye, bigatuma itekanye mu gutwara ibinyobwa biribwa (imitobe, divayi, amata) cyangwa ibikoresho byumye by’ibiribwa - ingenzi cyane mu gutunganya ibiribwa no gukora ibinyobwa. Ku ikoreshwa mu nganda, igaragaza ubudahangarwa bwiza ku mavuta, aside yoroshye, alkali, n’ibintu bishongesha, birinda kwangirika mu bihe bikomeye by’akazi.
Icya gatatu, imiterere yayo ishingiye ku mukoresha yongera ubushobozi bwo gukora: urukuta rw'imbere rworoshye cyane (Ra < 0.5 μm) rugabanya gutakaza imbaraga, rutuma amazi atembera neza, ifu, cyangwa imyuka mu buryo butabangamiranye mu gihe hirindwa ko ibisigazwa by'amazi byiyongera (byoroshya isuku no kugabanya ikiguzi cyo kubungabunga). Imiterere yoroheje (≈30% yoroheje kurusha imiyoboro ya rubber ifite umurambararo umwe) n'imiterere y'uruziga idahindagurika bituma byoroha kuyiyobora, kuyigonda no kuyizunguruka—ni byiza ku myanya mito (urugero, guhumeka kw'imashini, ibice bya moteri z'ubwato) cyangwa porogaramu zigendanwa (urugero, imashini zisuka amavuta mu buhinzi, ipompo z'aho bubaka). Ingano zishobora guhindurwa (umurambararo w'imbere: 25mm–300mm; ubunini bw'urukuta: 0.6mm–2mm) n'amahitamo y'amabara (abonerana, umukara, cyangwa asanzwe) birushaho guhinduka bitewe n'ibikenewe byihariye, kuva ku kohereza amazi mu buryo buciriritse bwa laboratwari kugeza ku gutwara amazi menshi mu bucukuzi bw'amabuye y'agaciro.
Amaherezo, ubushobozi bwayo bwo gukora ibintu bitandukanye bugera ku nganda: mu buhinzi, ikora nk'imiyoboro yo kuhira cyangwa imiyoboro yo gukurura/gusohora amazi; mu nganda, ikora nk'imiyoboro y'umwuka ikoreshwa mu mashini zikora imyenda cyangwa imiyoboro yo gukusanya ivumbi ry'ibikoresho byo gusiga ibyuma; mu gutunganya ibiribwa, ijyana ibintu hagati y'intambwe zo gukora; naho mu bucukuzi bw'amabuye y'agaciro, ifata uduce tw'amabuye y'agaciro asanzwe. Uburyo bworoshye bwo gukwirakwiza ibintu mu buryo butaziguye (bufite insinga z'icyuma zikozwe hasi, uburinzi bungana na 10² ohm / m) bwongera umutekano wo kohereza ibintu bishobora gushya, bigabanya ibyago byo gusohora amazi mu buryo butaziguye.
Muri make, iyi miyoboro ihuza imikorere myiza, iyubahirizwa ry'isuku, n'uburyo bworoshye bwo kuyikoresha—ibi bigatuma iba igisubizo gihendutse kandi kirambye ku bibazo bitandukanye byo gucunga ibikoresho.
