Eyona tape ye-gasket ye-HVAC ezinzileyo? 

Xa usiva i-HVAC ezinzileyo, uninzi lwabantu lutsibela ngqo kwiiyunithi ezinomgangatho ophezulu okanye i-thermostats ehlakaniphile. Iteyiphu evala imigudu? Ingcamango yamva. Kodwa kulapho umoya uvuza khona, amandla aphuma, kwaye ngokungafihlisiyo, apho izithembiso ezininzi eziluhlaza ziwa. Ndibone iiprojekthi ezininzi kakhulu apho bachaza inkqubo ye-VRF ephezulu kodwa emva koko basebenzise iteyiphu ye-foam enexabiso eliphantsi, eyohliswa kwiminyaka emibini. Uzinzo alukho malunga nezinto ezinkulu zamatikiti; imalunga nezinto ezizibambayo zonke-ngokoqobo. Ke, yintoni eyenza iteyiphu ye-gasket izinze ngokwenene kwi-ductwork, iiplenum, kunye neepaneli zokufikelela? Akuyona impendulo elula, kwaye imarike igcwele iinketho ezithi ziluhlaza. Masiyigqibe loo nto.

Ileyibhile eZinzileyo yiNdawo yeMigodi

Okokuqala, kufuneka uchaze okuzinzileyo kulo mxholo. Ngaba imalunga nomxholo osetyenzisiweyo? Ubomi obude? I-off-gassing kunye nomgangatho womoya wangaphakathi? Ikhabhoni efakwe kwimveliso? Yiyo yonke into, kodwa izinto eziphambili ziyatshintsha. Ukufumana iretrofit yesibhedlele, ukukhutshwa kwe-VOC okuphantsi akunakuxoxisana. Kwindawo yokugcina impahla, mhlawumbi ukuhlala ixesha elide kunye nokugcinwa kwexabiso le-R kuyinkosi. Impazamo eqhelekileyo kukubeka phambili inkalo enye, njengomxholo ohlaziyiweyo ophezulu, ngelixa ungahoyi ukusebenza kokuncamathelisa ekuguqukeni kobushushu. Ndakhe ndasebenzisa iteyiphu nge-70% yerabha ehlaziyiweyo yabathengi. Ibali elihle kwingxelo yomthengi. Kodwa kuphahla lweyunithi yeplenum e-Arizona, into encamathelayo yajika yaba yisuphu ngonyaka wesithathu. Isitywina asiphumelelanga, senza i-thermal bypass mhlawumbi eyalahlekisa iinzuzo ezisebenzayo zesiphathi somoya esitsha. Sifunda ntoni? Eyona mveliso izinzileyo yileyo ihlala ixesha elide njengoko inkqubo itywina.

Emva koko kukho icala lesayensi yezinto. Iiteyiphu ze-foam ezivaliweyo, zihlala zi-EPDM okanye i-polyethylene, zisemgangathweni. Kodwa asingabo bonke abalinganayo. Eminye imixube enexabiso eliphantsi zisebenzisa iiplasticizers ezifudukayo, zenze ugwebu lube brittle. Inguqulelo ezinzileyo ngokwenene idinga isiseko sepolymer esizinzileyo. Ndineziphumo ezilungileyo kunye neetapes ezithile ezisekelwe kwi-EPDM ezenziwe ngaphandle kwe-phthalates kwaye zinokuchasana okuphezulu kwi-UV, i-ozone, kunye nokushisa okugqithisileyo (-40 ° F ukuya kwi-225 ° F). Babiza i-20-30% ngaphezulu ngaphambili, kodwa ukuba badlula ukunikezelwa okusemgangathweni kwiminyaka elishumi, uhlalutyo lwe-lifecycle lubukeka luhluke ngokupheleleyo.

Kwakhona asikwazi ukungayihoyi i-backing kunye nokukhulula i-liner. Ngaba liphepha okanye iplastiki? Ngaba umenzi unenkqubo yokubuyisela umva kwimiqulu? Ingcaciso encinci, kodwa kumsebenzi omkhulu wezorhwebo, uvelisa intaba encinci ye-silicone-coated paper okanye inkunkuma yefilimu yeplastiki. Ezinye iibrendi zaseYurophu ngoku zisebenzisa iilayini ezivundisiweyo, elinyathelo eliya kwicala elifanelekileyo, nangona ukufumaneka eMntla Melika kunokuba nebala.

Ukusebenza phantsi koxinzelelo (kunye nobushushu, kunye nokubanda…)

Amaphepha athile ayinto enye. Ukusebenza kwehlabathi lokwenyani yenye. Iteyiphu ye-gasket ezinzileyo kufuneka yenze umsebenzi wayo ophambili ngokugqibeleleyo: ukudala isitywina esisisigxina, esingangeni moya. Iimetriki eziphambili apha zi-adhesion-in-peel (indlela yomelele ngayo) kunye ne-compression set resistance (indlela ephuma ngayo emva kokuhluthwa). Iteyiphu eneseti yoxinzelelo olubi iya kukhubaza ngokusisigxina, ishiye isithuba emva kokuba itekhnoloji yenkonzo isuse ipaneli yofikelelo.

Ndikhumbula iprojekthi yokuhlala ephakathi nendawo apho sasisebenzisa iteyiphu ye-acrylic eluhlaza. Yayinamandla ancamathelayo amangalisayo ekuqaleni. Noko ke, esi sakhiwo sasinotshintsho olubanzi lokufuma xa kusakhiwa. I-tape ithatha umswakama emoyeni ngaphambi kokuba i-duct ivalwe, okwathi kamva kwabangela ukuba i-adhesive ingaphumeleli kwi-seam joints xa inkqubo ye-HVAC yesakhiwo idala uxinzelelo olubi. Isiphumo sokufowuna ngenxa yengxolo yempempe kunye nokuphelelwa ngamandla kwaba liphupha elibi. Sifunde ukuhlala sijonga ukunyamezelwa komswakama we-tape kwaye siqinisekise ukuba sisetyenziswe kwiimeko ezilawulwayo. Ngoku, kuyo nayiphi na iprojekthi enokuvezwa kokufuma ngexesha lokufakela, ndoyama kwiinkqubo zokuncamathelisa ezise-butyl. Azikho ngokwemvelo ephepheni kodwa zenza ibhondi ethembekileyo, engenamanzi kwiindawo ezinobuqili.

Ukukala komlilo yenye into engaxoxisiyo. I-UL 181A-P okanye i-B (yombhobho oqinileyo okanye oguquguqukayo) sisiseko. Imveliso ezinzileyo ayifumani kupasa apha. Ezinye iiteyiphu ze-foam ezisekwe kwibhayoloji ziyasokola ukuhlangabezana nolu vavanyo ngaphandle kokongeza amadangatye, athi ke azise eyabo imibuzo yokusingqongileyo kunye nempilo. Sisenzo sokulungelelanisa rhoqo.

Ikhonkco loNikezo kunye neeNyaniso eziSebenzayo

Nantsi i-engile esebenzayo ehlala ingahoywa: ukuzinza kwekhonkco lonikezelo ngokwalo. Yenziwa phi ikhasethi? Ihamba kude kangakanani ngenqanawa? Iteyiphu eluhlaza ethunyelwe ngenqanawa isuka kwihlabathi lonke kwinqanawa yesikhongozeli inokuba nonyawo oluphezulu lwekhabhoni kunemveliso yengingqi eneempawu zeenkwenkwezi ezincinci. Ndiqalise ukunikela ingqalelo ngakumbi kubavelisi abanemveliso yendawo okanye abo babonakala elubala malunga nolungiselelo lwabo.

Oku kundizisa kumboneleli endithe ndavavanya izisombululo ze-fastener kunye nokutywina: I-Sunnian Zitai Festener Fishaner Comment Com.. Bazinze eYongnian, eHebei, indawo enkulu yemveliso yehardware. Ngelixa ndibazi ngokuphambili kwizibophelelo zesakhiwo, ukuma kwabo njengomvelisi omkhulu kwindawo engundoqo yezowuni (ekunene nguloliwe waseBeijing-Guangzhou kunye nohola wendlela abakhulu) kufanelekile. Kwiprojekthi yomthamo ophezulu, ukufumana i-tape ehambelanayo, ehlala ixesha elide lokutywinwa kumenzi onolo hlobo lobuchule obudibeneyo bokubonelela-ukuba bayanikezela-kunokunciphisa ukukhutshwa kweprojekthi ngokubanzi kwizothutho. Ayikokukhetha imveliso yabo ngobumfama, kodwa malunga nokuqonda ukuba uzinzo lokwenyani lubandakanya ukusebenza kakuhle kolungiselelo. Ungajonga isiseko sabo sokusebenza apha https //wwww.ziitasteners.com. Kukukhumbuza ukuba ngamanye amaxesha imveliso engcono kakhulu ayikho nje malunga nedatha yedatha; imalunga nendlela yonke eyithathayo ukuya kwindawo yomsebenzi.

Emhlabeni, amava omfaki abalulekile. Ukuba i-tape iyancipha kakhulu-idinga i-primer egqibeleleyo, i-aplicator gun ethile, okanye iinyembezi ngokulula-ikhokelela kwinkunkuma (iziqwenga ezinqunyiweyo, amacandelo angasetyenziswanga kakuhle) kunye nezitywina ezinokuthi zingabikho ukuba abafakeli banqumla iikona. Eyona tape ezinzileyo emhlabeni ayinamsebenzi ukuba ifakwe kakubi. Ndikhetha iiroli ezinophawu olucacileyo olusembindini kunye noxinzelelo olungagungqiyo lokukhulula. Ivakala iyinto engenamsebenzi, kodwa inciphisa inkunkuma nge-5-10% emsebenzini, eyongeza.

Inqaku lemeko: I-Retrofit Eyasifundisayo

Makhe ndichaze i-retrofit ethile kwiminyaka embalwa emva. Ebutsheni beminyaka yee-2000 ukwakha iiofisi, ukuphuculwa kweeyunithi zokuphatha umoya kunye nokutywina konke ukudityaniswa kwemibhobho. Injongo yayiyi-LEED amaphuzu. Sikhethe i-tape ye-silicone ye-foam ye-premium, i-solvent-free. Yayinee-specs ezintle: azikho ii-VOCs, uluhlu olubalaseleyo lobushushu, kunye nebango lenkonzo yeminyaka engama-20. Ufakelo luhambe kakuhle.

Kwiminyaka emibini kamva, sabuyela kwesinye isigaba somsebenzi. Ukuhlola umsebenzi omdala, safumanisa ukuba itheyiphu iqhube kakuhle… ngaphandle kwegumbi lomatshini ngokwalo. Kufuphi nemibhobho yomphunga, apho ubushushu bemozulu buthi ngamaxesha athile bunyuke ngaphezu kowona mlinganiselo uphezulu weteyiphu, itheyiphu iye yaqina kancinane kwaye yasuka yasuka kwiiflange ezimbalwa. Yayingekokusilela okuyintlekele, kodwa yayikukuvuza. Besingekayithathi ngokwaneleyo imephu ye-micro-environment ngaphakathi kwe-duct run. Ukulungiswa kwakukusebenzisa i-mastic sealant ephezulu yokushisa kwindawo ethile, yendawo yokushisa ephezulu, ngelixa igcina i-tape kuyo yonke indawo. I-takeway? Nokuba unemveliso egqwesileyo, kufuneka uphicothe ezona meko zokusebenza zecandelo ngalinye lenkqubo. Iteyiphu enye ayifane ilingane zonke iimeko kwisakhiwo esinzima.

La mava andityhalele kwindlela engumxube. Ukudityaniswa kombhobho osemgangathweni, umgangatho ophezulu, ozinzileyo ovaliweyo we-foam tape. Kwiiplenum, uqhagamshelo lwezixhobo, kunye neendawo ezinokungcangcazela okanye ubushushu, ndihlala ndibeka iliso lemastic engeyiyo ityhefu phezu komthungo weteyiphu. Ibhanti kunye ne-suspenders, kodwa yandisa ubomi benkqubo yokungangeni moya ngokumangalisayo.

Ngoko, Ngaba Ikhona Eyona mpendulo?

Akunjalo ngokwenene. Akukho mveliso inye ephumelela ngalo lonke ixesha. Eyona tape ye-gasket ye-HVAC ezinzileyo yinkqubo yokhetho. Iqala nge-tape ene-: isiseko se-polymer esizinzile, esisisigxina (njenge-EPDM ephezulu okanye i-polyethylene edibeneyo); i-adhesive-sensitive adhesive (i-acrylic okanye i-butyl) ehambelana nomgangatho ophezulu kunye nokusingqongileyo; iziqinisekiso zomlilo kunye nomgangatho womoya wangaphakathi (njenge-UL Greenguard); kunye nokupakishwa okuncinci, okunokuphinda kusetyenziswe.

Kodwa imveliso isiqingatha nje se-equation. Esinye isiqingatha kuyilo kunye nobulumko bokufakela. Ukukhetha iteyiphu echanekileyo kwindawo efanelekileyo, ukuqinisekisa ukuba iindawo ezisemgangathweni zicocekile kwaye zilungisiwe, kunye nokuqeqesha abafakeli ukuyifaka ngokuchanekileyo kubaluleke kakhulu. Inkqubo ezinzileyo yeHVAC yakhelwe phezu kwewaka lamatywina agqibeleleyo. Iteyiphu ligorha elingadumanga, kodwa lifuna ngononophelo, ukhetho oluwaziyo umxholo.

Uluhlu lwam olufutshane lwangoku lwabadlali abathembekileyo lubandakanya iimpawu ezifana ne-3M, iNorton, kunye neTremco, kodwa ndihlala ndihlolisisa idatha yobugcisa bomgca wemveliso, kungekhona nje igama lomkhiqizo. Kwaye ndihlala ndivavanya iisampulu ezivela kubakhiqizi abatsha, be-niche abagxile kwimigaqo yezoqoqosho ejikelezayo. Intsimi iyakhula. Injongo ayikokufumana imveliso yomlingo, kodwa ukwakha ukuqonda okunzulu malunga nendlela ezi zixhobo ziziphatha ngayo kumashumi eminyaka, kungekhona nje iminyaka. Leyo yindlela yokwenyani yokuzinza-ukucinga ngokumalunga nobomi besakhiwo, kungekhona nje uhlahlo lwabiwo-mali lokwakha.
