Washyizeho umupira mushya wa PVC kandi utegereje ko uzakora imyaka. Ariko gutsindwa gutunguranye birashobora gutera umwuzure, kwangiza ibikoresho, no guhagarika ibikorwa.

Umuyoboro mwiza wo mu bwoko bwa PVC urashobora kumara imyaka 20 mubihe byiza. Nyamara, igihe cyacyo cyo kubaho cyagenwe nimpamvu nko guhura na UV, guhuza imiti, ubushyuhe bwamazi, umuvuduko wa sisitemu, ninshuro ikoreshwa.

Iyi mibare yimyaka 20 nintangiriro, ntabwo ari garanti. Igisubizo nyacyo ni “biterwa.” Nabiganiriyeho na Budi, umuyobozi ushinzwe kugura nkorana na Indoneziya. Abona ibintu byose. Abakiriya bamwe bafiteindangantegogukora neza muri sisitemu yubuhinzi nyuma yimyaka 15. Abandi bagize valve byananiranye mumyaka ibiri. Itandukaniro ntirishobora na rimwe ubwaryo, ahubwo ni ibidukikije ririmo. Gusobanukirwa nibi bidukikije nuburyo bwonyine bwo guhanura igihe valve yawe izamara kandi ukareba ko igera kubushobozi bwayo bwuzuye.

Ni ikihe cyizere cyo kubaho cyumupira wa PVC?

Urashaka umubare woroshye kuri gahunda yawe yumushinga. Ariko gushingira ku ngengabihe yawe na bije yawe ukeka ko bishobora guteza akaga, cyane cyane niba valve yananiwe mbere yuko ubitekereza.

Icyizere cyo kubaho cyumupira wa PVC kiri hagati yimyaka mike kugeza kumyaka 20. Ibi ntabwo byakosowe. Igihe cyo kubaho giterwa ahanini nibidukikije bikora hamwe nubwiza bwibikoresho byacyo.

Tekereza igihe cyo kubaho kwa valve nkingengo yimari. Itangira kumyaka 20, kandi buri kintu gikaze "kimara" bimwe mubuzima bwihuse. Abakoresha cyane ni urumuri rwizuba UV no gukoresha kenshi. Umuyoboro ufunguye kandi ugafungwa inshuro amagana kumunsi uzashiraho kashe yimbere imbere yihuta kuruta imwe ihindurwa rimwe mukwezi. Mu buryo nk'ubwo, valve yashyizwe hanze mumirasire yizuba izahinduka intege nke mugihe runaka. Imirasire ya UV yibasira ingirabuzimafatizo muri PVC. Nyuma yimyaka mike, irashobora gucika intege kuburyo gukomanga gato bishobora kumeneka. Guhuza imiti, ubushyuhe bwinshi, hamwe numuvuduko ukabije nabyo bigabanya ubuzima bwayo. A.indangagaciro nzizabikozwe muri 100% isugi PVC hamwe nintebe ndende ya PTFE izaramba cyane kurenza valve ihendutse hamwe nuwuzuza, ariko na valve nziza izananirwa hakiri kare iyo ikoreshejwe mubihe bitari byiza.

Ibintu Bigabanya PVC Agaciro Ubuzima

Nibihe byizewe byumupira wa PVC?

PVC isa na plastiki, kandi plastike irashobora kumva ifite intege nke. Ufite impungenge ko ishobora kumeneka cyangwa gutemba munsi yigitutu, cyane cyane ugereranije nicyuma kiremereye.

Indangagaciro nziza ya PVC imipira yizewe cyane kubyo igenewe. Ubwubatsi bwabo bwa pulasitike bivuze ko badakingiwe rwose ingese n’imyubakire itera imyanda y'ibyuma kunanirwa cyangwa gufata igihe.

Kwizerwa ntabwo ari uguturika gusa. Nibyerekeye niba valve ikora mugihe ubikeneye. Budi yambwiye inkuru ivuga umwe mubakiriya be mu nganda z’amafi. Kera bakoreshaga imipira yumupira wumuringa, ariko amazi yumunyu muke yatumaga yangirika. Nyuma yumwaka, ibibaya byari bikomeye cyane kubora kuburyo bidashobora guhinduka. Bagombaga gusimburwa. Bahinduye imipira yacu ya PVC. Nyuma yimyaka itanu, izo valve za PVC zirahinduka neza nkumunsi zashyizweho. Ubu ni bwo kwizerwa kwukuri kwa PVC. Ntabwo ingese. Ntabwo ifunze nubunini cyangwa amabuye y'agaciro. Igihe cyose ikoreshwa mubipimo byumuvuduko / ubushyuhe kandi ikarindwa UV, imikorere yayo ntizitesha agaciro. Umuyoboro mwiza wa PVC ufite nezaIntebe za PTFEkandi byizeweEPDM O-impetaitanga urwego rwigihe kirekire, ruteganijwe kwizerwa ibyuma akenshi bidashobora guhura mubikorwa byamazi.

Umwanya wumupira wigihe kingana iki?

Urimo kugereranya valve ya PVC numuringa. Icyuma umuntu yumva kiremereye, bityo kigomba kuba cyiza, sibyo? Iki gitekerezo kirashobora kugutera guhitamo valve itariyo kumurimo.

Imipira yumupira nibyiza mumyaka mirongo iyo ikoreshejwe neza. Kuri PVC, ibi bivuze gukoresha amazi akonje nta UV igaragara. Kubyuma, bisobanura amazi meza, adashobora kwangirika. A.PVCakenshi byerekana aicyumamubidukikije bikaze.

“Ni byiza kugeza ryari?” ni ikibazo rwose "Ni iki cyiza kuri?" Umuyoboro wo hejuru wicyuma wumupira wumuringa uratangaje, ariko ntabwo ari byiza guhitamo pisine yo koga irimo amazi ya chlorine, ishobora gutera ibyuma mugihe runaka. Umuyoboro wumuringa nuguhitamo rusange-intego, ariko bizananirana muri sisitemu ifite ifumbire cyangwa amazi acide. Aha niho PVC imurikira. Nuburyo bwiza bwo guhitamo ibintu byinshi bishingiye kumazi, harimo kuhira, ubworozi bw'amazi, ibidengeri, hamwe n'amazi rusange. Muri ibi bidukikije, ntabwo bizangirika, bityo bikomeza gukora neza imyaka myinshi. Nubwo atari byiza kumazi ashyushye cyangwa umuvuduko mwinshi, nuguhitamo gusumba niche yihariye. Umuyoboro wa PVC ukoreshwa neza uzaba "mwiza kuri" igihe kirekire kuruta icyuma gikoreshwa nabi. Abakiriya ba Budi batsinze cyane ni bo bahuza ibikoresho bya valve n'amazi, ntabwo ari imyumvire y'imbaraga gusa.

Ese imipira yumupira igenda nabi?

Umuyoboro wawe wahagaritse gukora. Uribaza niba yarashaje gusa cyangwa niba hari ikintu cyihariye cyateye kunanirwa. Kumenya impamvu byananiranye nurufunguzo rwo kubikumira ubutaha.

Nibyo, imipira yumupira igenda nabi kubwimpamvu nyinshi zisobanutse. Kunanirwa gukunze kugaragara ni kashe yashaje kuva ikoreshwa kenshi, kwangirika kwa UV bitera ubugome, kwibasira imiti kubikoresho, cyangwa kwangirika kumubiri biturutse ku ngaruka cyangwa gukomera cyane.

Imipira yumupira ntabwo ihagarika gukora gusa kubera imyaka; igice runaka kirananirana. Ikintu gikunze gutsindwa ni kashe y'imbere. Intebe za PTFE zifunga umupira zirashobora gushira nyuma yibihumbi n'ibihumbi bifunguye / bifunze, biganisha kumeneka gato. EPDM O-impeta kuruti nayo irashobora gushira, bigatera kumeneka. Nibisanzwe kwambara no kurira. Impamvu ya kabiri nyamukuru ni kwangiza ibidukikije. Nkuko twabiganiriyeho, urumuri rwa UV ni umwicanyi, bigatuma umubiri wa valve ucika. Imiti itari yo irashobora guhindura PVC yoroshye cyangwa gusenya O-impeta. Inzira ya gatatu igenda nabi nukwishyiriraho nabi. Ikosa rikunze kugaragara mbona ni abantu barengeje urugero-insinga za PVC. Bapfunyika kaseti cyane hanyuma bagakoresha umugozi munini, ushobora gutobora umubiri wa valve neza. Gusobanukirwa nuburyo bwo kunanirwa bigufasha kurinda igishoro cyawe no kwemeza ko kimara.

Umwanzuro

Umuyoboro mwiza wa PVC urashobora kumara imyaka mirongo. Imibereho yacyo iterwa nigihe kandi nibindi byinshi kubikoresha neza, kurinda urumuri rwa UV, hamwe nuburyo bukwiye bwa sisitemu yo kubishyira mu bikorwa.
