Umhlahlandlela Wokukhetha Amapayipi Enjoloba Nepulasitiki: Ukuvikela Ukushisa, Ukuvimbela Ukuvunda kanye Nokuvinjelwa Komlilo kwe-B1
Ezinhlelweni ze-HVAC, amapayipi okulethwa ashisayo nabandayo aphakathi nendawo, amanethiwekhi amapayipi ezimboni kanye namaphrojekthi okunikezwa kwamanzi nokushisa kamasipala, izinto zokuvala amapayipi zendabuko zivame ukuhlushwa ukumuncwa kwamanzi, ukujiya, ukudlidliza, kanye nokungasebenzi kahle. Lezi zinkinga azikhulisi nje kuphela ukulahlekelwa ukushisa nokubanda kanye nezindleko zokusebenza, kodwa futhi zifinyeza impilo yesevisi iyonke yezinhlelo zamapayipi. Njengezinto zokuvala i-foam eziguquguqukayo ze-tubular, ipayipi lerabha nepulasitiki linesakhiwo esihle samaseli avaliwe, linikeza ukuvala okuhle kakhulu, ukumelana nomswakama, ukusebenza okuvimbela ilangabi le-B1, kanye nokuguquguquka kokuvala ukudlidliza. Ungumkhiqizo okhethwayo wokuvala ukushisa nokuvikela zonke izinhlobo zamapayipi ayindilinga, asetshenziswa kabanzi ezakhiweni zezentengiselwano, izinhlelo zokupholisa umoya eziphakathi, izikhungo zeketanga elibandayo, imikhakha yezimboni zamakhemikhali nezilula, izinhlelo zokusebenza zasolwandle kanye neminye imikhakha eminingi.
Yenziwe kakhulu ngerabha ye-nitrile kanye ne-polyvinyl chloride enezithasiselo ezinobungani nemvelo, ipayipi yerabha kanye nepulasitiki yenziwa ngokuxuba, ukubopha amaseli avaliwe kanye nokubumba. Ihlukaniswa njengomkhiqizo wokuvikela ukushisa werabha ye-foam oguquguqukayo kanye nepulasitiki futhi ihambisana nezinga likazwelonke le-GB/T 17794-2021. Ipayipi lithambile, liyanwebeka kakhulu, futhi lakheke kahle, linokumelana okuhle kwamanzi, futhi alidingi ungqimba olwengeziwe oluvikela umswakama. Uma liqhathaniswa namapayipi okuvikela aqinile, linikeza ukuqina okukhulu kanye nokuguquguquka ukuze lilingane namapayipi ahlukahlukene agobile futhi anomumo okhethekile. Lipayipi lokuvikela elisebenzayo nelinobungani nemvelo elivame ukusetshenziswa ezakhiweni zomphakathi kanye namanethiwekhi amapayipi ezimboni.
1. Isakhiwo Samaseli Avaliwe Aminyene Sokumelana Nomswakama Nokuvimbela Ukuminyana
Njengoba inamaseli avaliwe aphelele futhi azimele, ipayipi linomuncu omncane kakhulu wamanzi kanye nokumelana nomswakama okuphezulu. Umhwamuko wamanzi awukwazi ukungena ezintweni, okuvimbela ngokuyisisekelo umswakama, ukwanda kanye nokuwohloka kokusebenza. Ngokuguquguquka okuvelele, ugoqa eduze izindonga zangaphandle zamapayipi ngamajoyinti aqinile, uvimba umhwamuko wamanzi wangaphandle kanye nokungena komoya futhi ubhekana ngempumelelo nezinkinga ezivamile zokuminyana kanye nokuconsa emapayipini. Umelana nokugoba, ukuqhekeka kanye nokugaywa ngesikhathi sokusebenza isikhathi eside, ukuqinisekisa ukusebenza okuzinzile kohlelo lonke lokuvikela amapayipi.
2. Ukushisa Okuphansi Kokushisa Kokuvikela Okusebenzayo Nokonga Amandla
Lo mkhiqizo unikeza ukusebenza okuphezulu kokuvikela ukushisa ngokushisa okungu-≤0.034 W/(m·K), okwenza isithiyo sokushisa esizinzile. Ugcina ukushisa kwamapayipi amanzi ashisayo futhi uhlinzeka ngokugcinwa kokubanda kwamapayipi amanzi abandayo kanye namapayipi okugcina abandayo, kunciphisa kakhulu ukulahleka kokushisa nokubanda futhi kunciphise ukusetshenziswa kwamandla kwemishini yokupholisa umoya, yokuqandisa kanye neyokushisa. Ukusebenza kwawo kokushisa kuhlala kuzinzile ngaphansi kokushisa nomswakama okushintshashintshayo, ngakho-ke umphumela wokuvikela awunciphisi kakhulu, uletha imiphumela ehlala isikhathi eside nethembekile yokonga amandla.
3. B1 Izinto Ezivimbela Umlilo Zokuthuthukisa Ukuphepha Komlilo Okuphelele
Ipayipi lerabha nepulasitiki lifinyelela izinga le-B1 elivimbela umlilo njengoba kuchaziwe ku-GB 8624-2012 ejwayelekile ngokusebenza okuthembekile kokuphepha komlilo. Uma livezwa emalangabini avulekile, liba yi-carbon kancane futhi ngeke livuthe noma lisakaze amalangabi. Likhiqiza umusi omncane futhi alinawo umusi onobuthi ngesikhathi sokusha. Lifanelekela izindawo ezibalulekile zokuvimbela umlilo njengezindawo zokwakha zangaphakathi, amakamelo emishini, imihubhe yomoya kanye nama-workshop ezimboni, lihlangabezana ngokugcwele nezindinganiso zokwamukelwa komlilo ezakhiweni zomphakathi, ezakhiweni eziphakeme kanye nezitshalo zezimboni, liqinisekisa ukusetshenziswa okuphephile.
4. Ububanzi Bokushisa Okubanzi, Ukudambisa Ukudlidliza kanye Nokuphila Kwenkonzo Ende
Ipayipi yerabha nepulasitiki ingasebenza kahle ebangeni lokushisa elisukela ku--40°C kuya ku-105°C. Imelana namazinga okushisa aphezulu naphansi, i-asidi, i-alkali, isikhunta kanye nokuguga, ivumelana nezimo zokusebenza ezinzima kufaka phakathi izindawo zangaphakathi nangaphandle, ama-workshop anomswakama kanye nemizila yokungenisa umoya. Ukuqina kwayo okuphezulu kunciphisa ngempumelelo ukudlidliza kanye nokuzwakala okubangelwa ngesikhathi sokusebenza kwepayipi futhi inikeza imiphumela yokumunca umsindo ukuthuthukisa indawo yasendaweni. Ngaphansi kwezimo zokusebenza ezijwayelekile, impilo yayo yesevisi ingadlula iminyaka eyi-15, kunciphisa izindleko zokugcinwa nokufakwa esikhundleni okulandelayo. Njengoba ingenayo i-formaldehyde nephunga, inobungani nemvelo futhi ihlangabezana nezidingo zezinto zokwakha zesimanje eziluhlaza.
5. Ukufakwa Okulula Kwezinhlelo Zokusebenzisa Amapayipi Ahlukahlukene
Ilula futhi kulula ukuyisika, ipayipi alidingi amathuluzi ayinkimbinkimbi futhi livumela ukufakwa okuguquguqukayo. Lingafakwa ngqo emapayipini noma ligoqwe futhi lilungiswe ngemva kokusika okude, futhi lisebenza kahle kumapayipi agobile kanye nama-reducer. Ukwakhiwa okulula kusiza ukunciphisa isikhathi sephrojekthi futhi konge izindleko zabasebenzi. Emasimini okwakha, lisetshenziselwa amapayipi omoya opholile ophakathi, amapayipi okuhambisa amanzi kanye nawokukhipha amanzi kanye namanethiwekhi amapayipi okushisa. Emasimini ezimboni, lisetshenziselwa amapayipi okulethwa ngamakhemikhali, amapayipi okuxhuma imishini kanye namapayipi okusekela olwandle. Sihlinzeka ngohlu oluphelele lobubanzi bamapayipi kanye nemininingwane ngokucubungula okwenziwe ngokwezifiso okutholakalayo. Ungakhetha imikhiqizo efanele ngokuya ngezimo zokusebenza zangempela ukuze ulinganisele ukusebenza kwesicelo kanye nezindleko zephrojekthi.
Njengomkhiqizi oqondile, sinikeza amapayipi enjoloba nepulasitiki anemininingwane ephelele enesitokwe esanele. Osayizi abangejwayelekile abangokwezifiso, ubuso obukhethekile kanye nezinsizakalo ze-OEM kuyasekelwa. Imibhalo ephelele yokuthumela kwamanye amazwe iqinisekisa ukusulwa kwempahla okubushelelezi emhlabeni jikelele. Zizwe ukhululekile ukuxhumana nathi ukuze uthole ama-oda amaningi, isiqondiso sokukhetha iphrojekthi noma izingcaphuno zakamuva. Sizokunikeza izixazululo zobungcweti nezibanzi zokufakwa kwepayipi.
