Uzama uku-oda ama-valve, kodwa umthengisi oyedwa uwabiza nge-PVC kanti omunye uwabiza nge-UPVC. Lokhu kudideka kukwenza ukhathazeke ngokuthi uqhathanisa imikhiqizo ehlukene noma uthenga izinto ezingalungile.
Kuma-valve ebhola aqinile, awukho umehluko ongokoqobo phakathi kwe-PVC ne-UPVC. Womabili la magama asho okufanayoi-polyvinyl chloride engafakwanga ipulasitiki, eqinile, imelana nokugqwala, futhi ilungele izinhlelo zamanzi.
Lona omunye wemibuzo evame kakhulu engiyitholayo, futhi udala ukudideka okungadingekile ku-supply chain. Ngisanda kukhuluma no-Budi, umphathi wokuthenga ovela kumsabalalisi omkhulu wase-Indonesia. Abathengi bakhe abasha abasha babebhajwa, becabanga ukuthi badinga ukuthola izinhlobo ezimbili ezihlukene zamavalvu. Ngamchazela ukuthi kuma-valve aqinile esiwakhiqiza e-Pntek, futhi engxenyeni enkulu yemboni, amagama asetshenziswa ngokushintshana. Ukuqonda ukuthi kungani kuzokunikeza ukuzethemba ezinqumweni zakho zokuthenga.
Ingabe ukhona umehluko phakathi kwe-PVC ne-UPVC?
Ubona ama-akhronimi amabili ahlukene futhi ngokwemvelo ucabange ukuthi amelela izinto ezimbili ezihlukene. Lokhu kungabaza kunganciphisa amaphrojekthi akho njengoba uzama ukuqinisekisa ukucaciswa okulungile.
Empeleni, cha. Esimweni samapayipi aqinile nama-valve, i-PVC ne-UPVC ziyafana. I-“U” ku-UPVC imele “unplasticized,” osekuvele kuyiqiniso kuwo wonke amavalvu e-PVC aqinile.
Ukudideka kuvela emlandweni wepulasitiki. I-Polyvinyl chloride (PVC) iyisisekelo sezinto. Ukuze ivumelane nezimo emikhiqizweni efana namapayipi angadini noma izintambo zikagesi, abakhiqizi bengeza izinto ezibizwa ngokuthi ama-plasticizers. Ukuze uhlukanise ifomu lokuqala, eliqinile enguqulweni eguquguqukayo, igama elithi "unplasticized" noma "UPVC" livele. Kodwa-ke, ngezinhlelo zokusebenza ezifana nezinhlelo zamanzi ezinomfutho, awusoze wasebenzisa inguqulo eguquguqukayo. Wonke amapayipi e-PVC aqinile, okokufakwayo, nama-valve ebhola, ngokwemvelo yawo, awenziwe ngepulasitiki. Ngakho-ke, nakuba ezinye izinkampani zilebula imikhiqizo yazo ngokuthi “UPVC” ukuze icace kakhudlwana, kanti ezinye zivele zisebenzisa i-“PVC” evame kakhulu, zibhekisela kwinto efanayo ncamashi eqinile, eqinile. KwaPntek, simane sibabizeAma-valve ebhola e-PVCngoba yitemu elivame kakhulu, kodwa wonke angama-UPVC ngokobuchwepheshe.
Ingabe ama-valve ebhola e-PVC alungile?
Uyabona ukuthi i-PVC iyipulasitiki futhi ibiza kancane kunensimbi. Lokhu kukwenza ubuze ikhwalithi yayo futhi uzibuze ukuthi ingabe iqinile ngokwanele ezinhlelweni zakho ezibucayi, zesikhathi eside.
Yebo, ama-valve ebhola e-PVC asezingeni eliphezulu alungele inhloso yawo. Azikwazi ukugqwala nokugqwala, azisindi, futhi zinikeza impilo ende yesevisi emanzini abandayo, ngokuvamile asebenza ngaphezu kwamavalvu ensimbi.
Inani labo alikho nje ezindlekweni zabo eziphansi; kusekusebenzeni kwabo ezindaweni ezithile. Amavalvu ensimbi, njengethusi noma insimbi, azogqwala noma agqwale ngokuhamba kwesikhathi, ikakhulukazi kumasistimu anamanzi ahlanzekile, amanzi anosawoti, noma amakhemikhali athile. Lokhu kugqwala kungabangela ukuthi i-valve ibambe phezulu, kwenze kube nzima ukuphenduka esimweni esiphuthumayo. I-PVC ayikwazi ukugqwala. Ayisebenzi ngamakhemikhali ezithasiselweni eziningi zamanzi, usawoti, nama-asidi athambile. Yingakho amakhasimende akwa-Budi embonini ye-aquaculture yasogwini e-Indonesia esebenzisa amavalvu e-PVC kuphela. Amanzi anosawoti angacekela phansi amavalvu ensimbi eminyakeni embalwa nje, kodwa amavalvu ethu e-PVC ayaqhubeka nokusebenza kahle iminyaka eyishumi noma ngaphezulu. Ngolunye uhlelo lokusebenza olungaphansi kuka-60°C (140°F), aI-valve yebhola ye-PVCakuyona nje inketho “eshibhile”; kuvame ukukhetha okuthembeke kakhudlwana futhi okuhlala isikhathi eside ngoba akusoze kwathatha ukugqwala.
Iluphi uhlobo olungcono kakhulu lwe-valve yebhola?
Ufuna ukuthenga i-valve “engcono kakhulu” ukuze uqinisekise ukuthi uhlelo lwakho luthembekile. Kodwa ngezinto eziningi ezitholakalayo, ukukhetha okungcono kakhulu kuzwakala kukhungathekisa futhi kuyingozi.
Ayikho i-valve yebhola “engcono kakhulu” yawo wonke umsebenzi. I-valve engcono kakhulu yileyo into yayo kanye nomklamo wayo okufanelana kahle nezinga lokushisa lesistimu yakho, ukucindezela, nendawo yamakhemikhali.
"Okuhle kakhulu" kuhlale kuhlobene nohlelo lokusebenza. Ukukhetha okungalungile kufana nokusebenzisa imoto yezemidlalo ukudonsa amatshe—kuyithuluzi elingalungile lomsebenzi. I-valve yensimbi engagqwali imnandi kakhulu emazingeni okushisa aphezulu kanye nezingcindezi, kodwa iyabiza ngokwedlulele ohlelweni lokujikeleza kwamachibi, lapho i-valve ye-PVC iphakeme ngenxa yokuqina kwayo.ukumelana ne-chlorine. Ngihlale ngiqondisa ozakwethu ukuthi bacabange ngezimo ezithile zephrojekthi yabo. I-valve ye-PVC ingumpetha wezinhlelo zamanzi abandayo ngenxa yokumelana nokugqwala kanye nezindleko zayo. Ukuze uthole amanzi ashisayo, udinga ukwenyukela phezuluI-CPVC. Ngegesi ephezulu yokucindezela noma uwoyela, ithusi liyisinqumo sendabuko, esithembekile. Ekusetshenzisweni kwezinga lokudla noma amakhemikhali abola kakhulu, insimbi engagqwali ngokuvamile iyadingeka. Inketho "engcono kakhulu" yileyo ehlinzeka ngokuphepha okudingekayo nokuhlala isikhathi eside ngezindleko eziphansi kakhulu.

|---|---|---|---|
| I-PVC | Amanzi Abandayo, Amachibi, Ukunisela, Ama-Aquariums | ~60°C (140°F) | Ngeke igle, iyathengeka. |
| I-CPVC | Amanzi Ashisayo Nabandayo, Imboni Emaphakathi | ~90°C (200°F) | Ukumelana nokushisa okuphezulu kune-PVC. |
| Ithusi | Amapayipi, Igesi, Ingcindezi Ephezulu | ~120°C (250°F) | Ihlala isikhathi eside, ilungele ama-seal anengcindezi ephezulu. |
| Insimbi engagqwali | Ibanga Lokudla, Amakhemikhali, I-High Temp/Pressure | >200°C (400°F) | Amandla aphezulu kanye nokumelana namakhemikhali. |
Uyini umehluko phakathi kwe-PVC U ne-UPVC?
Lapho nje ucabanga ukuthi uyaqonda i-PVC iqhathaniswa ne-UPVC, ubona okuthi “PVC-U” kudokhumenti yobuchwepheshe. Leli gama elisha lengeza olunye ungqimba lokudideka, likwenza uqagele ukuqonda kwakho okwesibili.
Awukho nhlobo umehluko. I-PVC-U ingenye nje indlela yokubhala i-PVC. I-“-U” iphinde imele i-unplasticized. Kuyingqungquthela yokuqamba amagama evame ukubonakala kumazinga aseYurophu noma amazwe ngamazwe (njenge-DIN noma i-ISO).
Cabanga ngakho njengokuthi "amadola ayi-100" ngokumelene "namadola ayi-100." Amagama ahlukene ento efanayo ncamashi. Emhlabeni wamapulasitiki, izifunda ezihlukene zakha izindlela ezihluke kancane zokulebula le nto. ENyakatho Melika, elithi “PVC” igama elivamile lepayipi eliqinile, futhi elithi “UPVC” kwesinye isikhathi lisetshenziselwa ukucaca. E-Europe nangaphansi kwezindinganiso zamazwe ngamazwe, i-“PVC-U” igama lobunjiniyela elisemthethweni elizocacisa “okungafakwanga ipulasitiki.” Kumthengi onjengoBudi, lolu wucezu olubalulekile lolwazi lweqembu lakhe. Uma zibona ithenda yaseYurophu ecacisa amavalvu e-PVC-U, bazi ngokuzethemba ukuthi amavalvu ethu ajwayelekile e-PVC ahlangabezana nemfuneko ngokuphelele. Konke kuza endabeni efanayo: i-polymer ye-vinyl eqinile, eqinile, engenaplastic elungele ama-valve ebhola. Ungabambeki ezincwadini; gxila ezintweni ezibonakalayo namazinga okusebenza.
Isiphetho
I-PVC, i-UPVC, ne-PVC-U zonke zibhekisela ezintweni ezifanayo eziqinile, ezingenapulasitiki ezilungele amavalvu ebhola lamanzi abandayo. Umehluko wamagama yizimiso zesifunda noma zomlando nje.
