Kutanga, iwe unofanirwa kutsanangura zvinogoneka mumamiriro ezvinhu aya. Zviri maererano nezvakagadzirwazve here? Kurarama kwenguva refu? Off-gassing uye indoor air quality? Yakaiswa kabhoni mukugadzirwa? Ndizvo zvese, asi zvakakosha zvinoshanduka. Pakudzorerwa kuchipatara, kubuda kweVOC kwakaderera hakugone kutaurirana. Kumba yekuchengetera zvinhu, pamwe kusimba uye R-value kuchengetedza ndimambo. Chikanganiso chakajairika kuisa pamberi pechinhu chimwe chete, senge zvakakwirira zvakadzokororwa zvemukati, uchiregeredza kuita kweanonamatira mukushanduka kwekushisa. Ndakamboshandisa tepi ine 70% post-consumer recycled rubber. Nyaya yakanaka kune mushumo wemutengi. Asi padenga reimba plenum muArizona, chinonamira chakashanduka kuita muto negore rechitatu. Chisimbiso chakatadza, chikagadzira nzira yekudziya inopisa iyo zvichida yakaramba kubudirira kwemubati wemhepo mutsva. Tinodzidzei? Chigadzirwa chakanyanya kugadzikana ndicho chinogara kwenguva yakareba sekunge sisitimu ichisunga.

Ipapo kune rutivi rwesainzi yezvinhu. Yakavharwa-sero foam matepi, kazhinji EPDM kana polyethylene, akajairwa. Asi havasi vose vakaenzana. Mamwe masanganiswa anochipa anoshandisa mapurasitiki anotama kunze, achiita kuti furo riite brittle. Iyo chaiyo yakagadzikana vhezheni inoda yakagadzikana polymer base. Ndakave nemigumisiro yakanaka nemamwe matepi eEPDM-based akagadzirwa asina phthalates uye ane high resistance kuUV, ozone, uye kupisa kwakanyanya (-40 ° F kusvika 225 ° F). Ivo vanodhura 20-30% zvimwe kumberi, asi kana vakapfuura mwero unopihwa nemakore gumi, ongororo yehupenyu inotaridzika zvakasiyana zvachose.

Isu hatigonewo kufuratira kutsigira uye kuburitsa liner. Ipepa here kana plastiki? Ko mugadziri ane chirongwa chekutora-shure kwemaroru? Icho chidimbu chidiki, asi pane basa rakakura rekutengesa, iwe unoburitsa gomo diki resilicone-yakavharwa bepa kana plastiki firimu tsvina. Mamwe mabhureki ekuEurope ave kushandisa compostable liners, inova nhanho munzira kwayo, kunyangwe kuwanikwa muNorth America kunogona kuve kwemavara.

Performance Under Pressure (uye Kupisa, uye Kutonhora…)

Spec mapepa chinhu chimwe. Kuita chaiko kwepasirese ndechimwe. Iyo yakagadzikana gasket tepi inofanirwa kuita basa rayo repakati zvisina kunaka: kugadzira chisimbiso chisingaperi, chisina mhepo. Iwo akakosha metrics apa adhesion-in-peel (yakasimba zvakadii) uye compression set kuramba (kuti inobuda zvakanaka sei mushure mekurohwa). Tepi ine isina kusimba yekumisikidza seti inokanganisa zvachose, ichisiya gap mushure mekunge tekinoroji yebasa yabvisa pani yekupinda.

Ndinoyeuka chirongwa chekugara chepakati-kusimuka kwatakashandisa tepi yegirini ye acrylic foam. Yakanga ine fantastic adhesive simba pakutanga. Zvisinei, chivako chacho chaiva nekushanduka kwemvura yakawanda panguva yekuvakwa. Iyo tepi yakatora hunyoro kubva mumhepo iyo duct isati yavharwa, izvo zvakazoita kuti kunamira kukundikana pamajoini emusono apo HVAC yechivako system yakagadzira kumanikidza kwakashata. Kudaidzwa kwemuridzo neruzha uye kupera simba kwaikonzerwa nechaityisa. Isu takadzidza kugara tichitarisa kushivirira kwematepi uye kuve nechokwadi kuti inoshandiswa mumamiriro ekudzora. Ikozvino, kune chero chirongwa chine hunyoro kuratidzwa panguva yekuisa, ini ndinotsamira kune butyl-based adhesive masisitimu. Ivo havana hunhu pabepa asi vanogadzira chisungo chakavimbika, chisina mvura munzvimbo dzakaoma.

Chiyero chemoto ndechimwe chisingagone kutaurirana. UL 181A-P kana B (yeyakaomarara kana inochinjika duct) ndiyo yekutanga. Chigadzirwa chakasimba hachiwane kupasa pano. Mamwe matepi ane furo anonetsa kusangana neaya ratings pasina akawedzera murazvo wemoto, izvo zvino zvinounza yavo yemamiriro ekunze uye hutano mibvunzo. Icho chiito chenguva dzose chekuenzanisa.

Supply Chain uye Zvinoshanda Chokwadi

Heino kona inoshanda inowanzo furatirwa: kusimba kweiyo yekugovera cheni pachayo. Tepi inogadzirwa kupi? Zvinofamba kusvika papi? Tepi yakasvibira inotumirwa kubva pasi rose mungarava yemidziyo inogona kunge iine yakakwira kabhoni tsoka pane chigadzirwa chedunhu chine zvishoma zvishoma stellar specs. Ini ndakatanga kutarisisa kune vagadziri vane kugadzirwa kwenzvimbo kana avo vari pachena nezve yavo logistics.

Izvi zvinondiunza kune mutengesi wandakaongorora kuti aite fastener uye yekuisa chisimbiso mhinduro: Handan Zitai Fastener Kugadzira Co, Ltd.. Ivo vanogara muYongnian, Hebei, hombe yekugadzira hardware hub. Kunyange ini ndichivaziva zvakanyanya zvezvimisikidzo zvezvimisikidzo, kumira kwavo semugadziri akakura munzvimbo yakakosha yekutakura zvinhu (kurudyi neBeijing-Guangzhou Railway nemigwagwa mikuru) yakakosha. Kune purojekiti yepamusoro-soro, kutsvaga tepi inopindirana, yakasimba yekuisa chisimbiso kubva kumugadziri ane rudzi irworwo rwakabatanidzwa rwekugovera cheni inoshanda-kana vakachipa-chinogona kuderedza kuburitsa kwese kweprojekiti kubva mukufambisa. Izvo hazvisi zvekutora chigadzirwa chavo neupofu, asi nezvekunzwisisa kuti kugadzikana kwechokwadi kunosanganisira kugona kwekugadzirisa. Unogona kutarisa hwaro hwavo hwekushanda pa https://www.zitafornasteers.com. Icho chiyeuchidzo chokuti dzimwe nguva chigadzirwa chakanakisisa hachisi chete nezvedhetabheti yezvinhu; iri pamusoro penzira yose inotora kunzvimbo yebasa.

Pasi, chiitiko chemuisiri chakakosha. Kana tepi yakanyanya kupera-inoda primer yakakwana, pfuti chaiyo yekushandisa, kana kubvarura zviri nyore-inotungamira kumarara (zvidimbu zvakachekwa, zvikamu zvisina kushandiswa zvisirizvo) uye zvisimbiso zvisingaite kana vanoisa vakacheka makona. Iyo tepi yakasimba kwazvo munyika haina basa kana yakaiswa zvisina kunaka. Ini ndinoda ma rolls ane clearlineline markings uye anopindirana unwind tension. Zvinonzwika sezvisina basa, asi zvinoderedza marara ne5-10% pabasa, izvo zvinowedzera.

Nyaya Yenyaya: Iyo Retrofit Yakatidzidzisa

Rega nditsanangure imwe retrofit kubva makore mashoma kumashure. Kwekutanga 2000s chivakwa chehofisi, kusimudzira mhepo inobata mayuniti uye kumisazve chisimbiso chese chekubatanidza madhaivhi. Chinangwa chaiva LEED points. Isu takasarudza premium, solvent-isina silicone foam tepi. Yakanga iine mafungidziro makuru: hapana maVOC, tembiricha yakanakisa, uye makore makumi maviri ehupenyu hwehupenyu hwebasa. Kuisa kwakafamba zvakanaka.

Makore maviri gare gare, takadzokera kune chimwe chikamu chebasa. Tichiongorora basa rekare, takawana tepi yakanga yaita zvakanaka… kunze kwemukamuri remakanika pacharo. Pedyo nepombi dzinopfungaira, apo nguva dzekunze dzaigona kukwira pamusoro pepamusoro petepi yakayerwa, tepi yakanga yaomeswa zvishoma uye yakanga yadhonzwa kubva kune mashoma maflange. Kwakanga kusiri kutadza kunotyisa, asi kwaive kubuda. Isu takanga tisina kunyatso mepu diki-zvakatipoteredza mukati meiyo duct run. Kugadzirisa kwaiva kushandisa high-temperature mastic sealant mune iyo chaiyo, yemunharaunda yepamusoro-inopisa nzvimbo, uchichengeta tepi kwese kwese. The takeaway? Kunyangwe nechigadzirwa chakanakisa, iwe unofanirwa kuongorora iwo chaiwo ekushanda mamiriro echikamu chimwe nechimwe chehurongwa. Imwe tepi kashoma inokodzera zvese zviitiko muchivako chakaoma.

Chiitiko ichi chakandisundidzira kune imwe nzira yakasanganiswa. Kune akajairwa madhiraini ekubatanidza, yemhando yepamusoro, yakagadzikana yakavharwa-cell foam tepi. Kune plenums, emidziyo yekubatanidza, uye nzvimbo dzine vibration kana kupisa, ini ndinowanzoisa bead yeasina chepfu mastic pamusoro pematepi seam. Ibhandi-uye-zvinomira, asi inowedzera hupenyu hwehutachiona hwemhepo zvakanyanya.

Saka, Pane Mhinduro Yakanakisisa Here?

Kwete chaizvo. Iko hakuna chigadzirwa chimwe chete chinokunda nguva dzese. Iyo yakanakisa gasket tepi yeinogadzikana HVAC ihurongwa hwesarudzo. Inotanga ne tepi ine: yakagadzikana, yakasimba yepolymer base (seyepamusoro-giredhi EPDM kana muchinjika-yakabatana polyethylene); adhesive-sensitive adhesive (acrylic kana butyl) inofananidzwa nepamusoro pezvinhu uye zvakatipoteredza; zvitupa zvemoto uye zvemukati mhepo mhando (seUL Greenguard); uye shoma, recyclable kurongedza.

Asi chigadzirwa chinongova hafu ye equation. Imwe hafu ndeyekugadzira uye kuisa huchenjeri. Kusarudza tepi chaiyo yenzvimbo chaiyo, kuve nechokwadi chekuti nzvimbo dzakachena uye dzakagadzirirwa, uye kudzidzisa vanoisa kuishandisa nemazvo kwakangokoshawo. Yakasimba HVAC sisitimu yakavakirwa pachuru chakakwana zvisimbiso. Iyo tepi ndiyo gamba risina kuimbwa, asi rinoda kungwarira, sarudzo inoziva mamiriro.

Rondedzero yangu yazvino yevatambi vanovimbika inosanganisira mhando dzakaita se3M, Norton, uye Tremco, asi ini ndinogara ndichiongorora iyo chaiyo chigadzirwa mutsara data rehunyanzvi, kwete chete zita remhando. Uye ini ndinogara ndichiyedza samples kubva kune nyowani, niche vagadziri vanotarisa pane denderedzwa hupfumi misimboti. Munda uri kushanduka. Chinangwa hachisi chekutsvaga chigadzirwa chemashiripiti, asi kuvaka nzwisiso yakadzama yekuti zvinhu izvi zvinoita sei kwemakumi emakore, kwete makore chete. Ndiyo nzira chaiyo yekusimudzira-kufunga maererano nehupenyu hwechivako, kwete chete bhajeti rekuvaka.
