Vuba aha, navuganaga n'abakiriya benshi bakora mu bijyanye n'ubuhanga mu by'imiyoboro. Ndabona iyo uhisemo umuyoboro w'imbere bahora bahangayikishijwe n'iki kibazo: Umuyoboro wa Polyurethane naUmuyoboro wa Polypropylene, ni ikihe cyiza kurusha ibindi? Ibikoresho byose by'ibanze ni umuyoboro wa Spiral Seam Welded, ariko ibikoresho by'imbere biratandukanye, kandi imikorere n'igiciro biratandukanye cyane.
Uyu munsi, nifashishije urugero rw'uruganda rw'imiyoboro y'icyuma rwa Cangzhou Spiral Steel Pipe Factory, ndasobanura neza iki kibazo.
Reka dutangire n'umubumbe. Uyu ni wo musingi.
Nubwo igice cy'imbere cyaba gikozwe muri PU cyangwa PP, ibikoresho by'ibanze bihora ariUmuyoboro wometseho umushonge w'uruzigaHari inganda nyinshi muri Cangzhou zikora iki gicuruzwa, ariko Cangzhou Spiral Steel Pipes Group Co., Ltd. ni yo yonyine ishobora kugera ku rwego runini. Iyi sosiyete yashinzwe mu 1993, ifite ubuso bwa metero kare 350.000 muri Cangzhou, ifite umutungo wa miliyoni 680 z'amayuwani n'abakozi 680. Ishobora gukora toni 400.000 z'imiyoboro y'icyuma izunguruka ku mwaka, ifite agaciro ka miliyari 1.8 z'amayuwani - iki gipimo ni ingenzi mu nganda zo mu gihugu.
Ariko ikigaragaza neza igihe umuyoboro uzamara ni uburyo bwo gusiga irangi bufite ibyiciro bitatu.
Abantu benshi bibanda gusa ku gice cy'imbere, ariko birengagiza intambwe eshatu z'ingenzi: primer, kole, n'urwego rwo hanze rurwanya ingese. Reka tubisuzume kimwe kimwe.
Icyiciro cya 1: Primer ya Epoxy Resin
Ibi bishyirwa mu buryo bw'ifu kandi ubugari bwabyo ntibugomba kuba munsi ya mikorometero 60. Ntugasuzugure uru rwego ruto. Rushinzwe gufatana n'umuyoboro w'icyuma. Iyo primer idakozwe neza, nubwo yaba ifashe neza hejuru, ntacyo izaba imaze.
Icyiciro cya kabiri: kole ya PE
Uru rwego rushobora gusukurwa cyangwa gukurwamo. Ubunini buke ni mikorometero 140. Hari ibisobanuro bya tekiniki bikwiye kwitabwaho hano: Ibisabwa mu gutera ifu no kuyikuraho biratandukanye. Mu gihe uguze, menya neza ko ubaza umutanga uburyo akoresha. Bitabaye ibyo, iyo uyikuyemo, izakuraho uruhu, byaba ari ikibazo.
Icyiciro cya gatatu: Igitambaro cyo hanze cya polyethylene
Uru rwego nirwo rufite ubunini cyane kandi rukorwa binyuze mu gucukura cyangwa gusohora hakoreshejwe umuyoboro cyangwa urupapuro. Nyuma yo gupfuka, rugomba gukonjeshwa; bitabaye ibyo, ruzahinduka iyo rupfunyitse mu gihe cyo gutwara. Ubunini bwose bw'igipfuka buratandukana bitewe n'umurambararo w'umuyoboro. Niba umuyoboro ugomba gutwikirwa munsi y'ubutaka cyangwa ugashyirwa mu mitwaro ikomeye ya mekanike, ubunini bw'igipfuka bugomba kongerwaho milimetero 0.7 z'inyongera. Agaciro runaka gakunze gutangwa mu mbonerahamwe n'uwakoze, kandi ushobora guhitamo gusa ukurikije uko imeze.
Garuka ku kibazo cy'ibanze: PU lining cyangwa PP lining?
Mu magambo make, dore inama ishingiye ku bunararibonye: Imiyoboro ya polyurethane ifite ubushobozi bwo kudashira neza kandi ikwiriye gutwara ibikoresho birimo uduce duto, nk'ibice by'amazi n'amazi mabi;Imiyoboro ya polypropylene iriho imiyoborobifite ubushobozi bwo kurwanya ubushyuhe bwinshi no kurwanya ingese mu binyabutabire, kandi bikwiranye n'ibinyabutabire n'ibipimo by'ubushyuhe bwinshi.
Iyo ingengo y'imari y'umushinga ibikwemereye, birashoboka kandi kuvugana n'uruganda kugira ngo bakore igisubizo gihuriweho. Ariko, icyangombwa ni uko ubwiza bw'ibikoresho by'ibanze n'ipamba ry'imiyoboro ya Spiral Seam Welded Pipe rishobora kuba rijyanye n'ubuziranenge. Impamvu uruganda rwa Cangzhou Spiral Steel Pipe rwashoboye gukomera muri uru rwego mu myaka myinshi, mu by'ukuri, ni uko rugenzura inzira yose ubwayo - kuzungurutsa ibikoresho by'ibanze, gushyiramo ipamba, no guteranya umugozi w'imbere - ibyo bikaba byizewe cyane kuruta kwiringira abatanga ibicuruzwa bahuza ibicuruzwa byabo.
Nta gisubizo "kiboneye" gihari mu guhitamo umuyoboro, ariko hari uburyo bwiza bwo kuwukoresha. Ndizera ko iyi nkuru izagufasha kwirinda inzira zimwe na zimwe zitari ngombwa mu guhitamo hagati ya PU na PP.
