Right zvinhu sill plate gasket kukanganisa kwezvakatipoteredza? 

Paunonzwa kukanganiswa kwezvakatipoteredza uye sill plate gasket mumutsara mumwe chete, vanhu vazhinji vari mukutengesa vanobva vafunga nezvenyaya yacho pachayo-kazhinji yakavharwa-sero foam kana rabha. Asi iyo ingori pamusoro. Nyaya chaiyo, iyo inonyanya kukosha panzvimbo yebasa uye nekufamba kwenguva, ndeyehupenyu hwose: kubva kumushonga wemakemikari unoshandiswa mukugadzira, kusvika pakukwana uye hupenyu hurefu hunodzivirira kubuda kwesimba, kusvika pasi kusvika kune chimedu iwe wakasara wakabata pamagumo ekuisa. Haisi yekungoti ndeye yakasvibira zvinhu, ndezvekuti ndiyo zvinhu zvechokwadi pabasa racho kuti risave dongo mumakore mashanu.

Kuumbwa Kwezvinhu: Kupfuura Foam chete

Ngatitorei zvakananga. Mazhinji gaskets, kunyanya akachipa, anoshandisa EPDM kana PVC inosanganiswa nemapurasitiki. Izvi zvekuwedzera ndizvo zvinopa izvo zvinhu kuchinjika, asi zvinogona kubva-gasi inoputika organic komisheni (VOCs). Pazuva rinopisa, kuvhara sill plate, iwe unogona dzimwe nguva kunhuhwirira-iyo inopera, kunhuhwirira kwemakemikari. Hazvisi zvisingafadzi chete; chiratidzo chezviri kubuda. Ndakaona fungidziro dzinodaidza dzakaderera-VOC sealants asi ndozozvibatanidza negasket iro rinenge riri off-gassing plasticizers, richikanganisa kuedza kwese. Chinhu chakakodzera pano hachisi izwi rekutengesa; ndezvekuwana kuenzanisa pakati pekugara uye inertness. Mamwe matsva ethermoplastic polyolefin musanganiswa anoita seanovimbisa - kushoma-kubvisa gasi, yakanaka compression set kuramba - asi inodhura yakawanda. Kubatsirwa kwezvakatipoteredza kunokodzera mutengo wepamberi here? Ndiko kuverenga kwezuva nezuva.

Ipapo pane kabhoni tsoka yekugadzira. Apa ndipo panogumira nhaurirano dzese. Asi washanyira mafekitori, senge madhizaini ekugadzira hubs muHebei, China, unoona chiyero. Kambani yakadai Handan Zitai Fastener Kugadzira Co, Ltd., ichishanda munzvimbo huru yekugadzira, ine zvivakwa zvekuwana mbichana zvine mutsindo uye inogona kuderedza marara mukuumba maitiro. Nzvimbo yavo iri pedyo nemigwagwa mikuru yekufambisa seBeijing-Guangzhou Railway neBeijing-Shenzhen Expressway haisi nzvimbo yekutengesa chete; inoderedza hutsi hwezvifambiso hwekuendesa chigadzirwa kuchiteshi. Asi iyo flip side ndiyo mutengo wenharaunda wenzvimbo yekugadzira yakanyanya. Iyo yakaoma equation vazhinji vekupedzisira-vashandisi havamboona.

Takaedza 100% recycled rubber gasket pane chirongwa makore maviri kumashure. Pfungwa yacho yaive yakakwana: vhara loop, shandisa tsvina matai. Chokwadi chaiva chinotyisa. Iyo yekumanikidza set yaityisa-haina kudzoka shure mushure mekunge ndiro yepasi yakasungirirwa pasi. Mukati memwaka, takanga tine nyaya dzekupinda nemhepo. Chinangwa chezvakatipoteredza chaive chakanaka, asi chigadzirwa chakakundikana pabasa racho rekutanga: kuisa chisimbiso. Kukundikana ikoko kwaireva kushandiswa kwesimba kwepamusoro kwechivako uye kuitazve kwakazara, zvichiita kuti marara awedzere. Saka, iyo yakanyanyisa yezvakatipoteredza zvinhu dzimwe nguva ndiyo inogara hupenyu hwechimiro.

Installation Realities uye Waste Stream

Hapana anotaura nezve marara ari pasaiti. Gaskets inouya mumipumburu kana mitsetse. Unoyera, unocheka. The off-cuts? Vanoenda mudumpster. Kune purojekiti huru yekutengeserana, iyo inogona kuva masaga akawanda efuro kana zvimedu zverabha. Haisi ngozi, saka inoenda kumarara. Takatanga chirongwa chekutyaira nemutengesi mumwe chete kuti tidzore zvichemo zvekugadzirisa zvakare, asi zvinhu zvakazviuraya. Mutengo wekutakura wakasununguka, wakakura furo zvimedu zvekudzokera kune imwe nzvimbo wakapfuura chero rubatsiro. Yakaratidza gaka rakakura: dhizaini yechigadzirwa chekuguma-kwehupenyu. Kana gaskets akauya mune mamwe modular saizi kana nekutora-kumashure chirongwa chakabikwa mucheni yekugovera, senge vamwe vagadziri vari kuongorora nekurongedza, zvinogona kuchinja zvinhu.

Imwe mhedzisiro yakavanzika ndeyekunamatira. Mazhinji sill seal gaskets ane peel-and-stick backing. Iyo yekunamatira layer inowanzova petrochemical chigadzirwa. Kana iyo gasket inoda kutsiva (uye ivo vanotadza), iwe unosara uine inonamira panheyo yekongiri iyo mhuka yekubvisa, kazhinji inoda mishonga inonyungudutsa. Isu tafamba takananga kushandisa compression-chete gaskets pazvinogoneka, tichitsamira pamutoro wefastener kuvhara. Inobvisa inonamira tsvina rwizi zvachose. Inoda kunyatsojeka panguva yekumisikidza uye kumisa, asi iyo inochenesa sisitimu.

Ndinoyeuka retrofit apo taifanira kubvisa yekare, yakashatiswa gaskets furo. Dzakaputsika kuita zviuru netwudikidiki. Containment yaive yakashata. Yakanga isiri muchetura, asi yaive isiri-biodegradable particulate kusvibiswa. Chiitiko ichocho chakandiita mutsigiri akasimba wekutarisa kuderedzwa kwechimiro chechinhu. Ichangoshanduka kuita microplastics muvhu mumakore makumi matatu? Iyo yakavharwa-sero cross-yakabatana polyethylene inogona kuita zvirinani pano pane yakavhurika-sero furo rinotora mvura nekuputsika panyama.

Kuita kwakakosha: Iyo Energy Link

Kukanganisa kwakanyanya kwezvakatipoteredza kwea Sill Plate Gasket haisi kugadzirwa kwayo, asi kuita kwayo in situ. Gasket isingaite zvisina kunaka inotungamira mukudonha kwemhepo. Kudonha kwemhepo kunoreva kuti HVAC system yechivakwa inoshanda zvakanyanya. Iyo yakawedzera simba rekushandisa, kwemakumi emakore, inoderedza iyo yakamisikidzwa kabhoni mune gasket zvinhu pachayo. Ndakaita ongororo yekupisa yekufungidzira pazvivakwa uko sill chisimbiso chaive chisina kusimba chinongedzo-waikwanisa kuona bhiriji rinopisa richijeka sezuva. Kusarudza zvinhu zvakanaka isimba rekuchengetedza simba kutanga.

Apa ndipo pane ukobvu, density, uye kudzoreredza mwero zvine basa. Iyo gasket yakatetepa zvakanyanya kana isina kupora kupora pasi pemutoro wakasimba inogadzira gap. Ini ndinosarudza magaskets ane yakakwira kudzoreredza muzana (se90%+). Vanodhura zvakanyanya, asi vanochengetedza chisimbiso kunyange kana huni huchiderera kana kugadzikana zvishoma. Kuti kuperera kwenguva refu ndiko kukunda kwezvakatipoteredza. Zvinoshungurudza kana kukosha kweinjiniya kunocheka iyo gasket spec kuchengetedza madhora 0.50 pamutsara tsoka, zvichigona kudhura zviuru musimba rakarasika.

Iko kune zvakare kudyidzana nezvimwe zvinhu. Semuyenzaniso, kudzvinyirirwa-kurapwa sill mahwendefa anogona kuva yakakwirira mwando. Zvimwe zvinhu zvegasket hazvienderane uye zvinogona kudzikisira nekukurumidza kana uchigara uchisangana nemamwe mapreservatives. Iwe unoda chinhu chine makemikari inert munzvimbo iyoyo chaiyo. Idiki diki diki diki, asi kuita zvisizvo kunotungamira mukutadza nguva isati yakwana uye zvese zvine chekuita nemarara uye zvirango zvesimba.

Supply Chain uye Manufacturing Ethics

Paunotora zvinhu senge mafasteners kana gaskets kubva kune yakakura-mugadziri anogadzira, iwe uri kutenga mune yavo maitiro ezvakatipoteredza. Mugadziri akafanana Handan Zitai Fastener inoronga chokufambisa chayo chiri nyore sebhenefiti inokosha. Kubva pakuona kwekabhoni accounting, mashandiro anoshanda chikamu chechokwadi chekudzikisa tsoka yechigadzirwa. Asi iwe unofanirwa kubvunza zvakadzika: ko nezve maitiro avo ekugadzirisa mvura? Energy sosi yemichina yavo yekuumba? Ivo vanoshandisa zvakadzokororwa zvemukati mune yavo polymer feedstocks? Iyi haisi mibvunzo yaunowana yakapindurwa pane yakajairwa spec sheet; iwe unofanirwa kuchera, kana zviri nani zvakadaro, kuongorora.

Isu takashandura kumwe kutsvagisa kune vatengesi vanogona kupa wechitatu-bato rakasimbiswa Environmental Product Declarations (EPDs). Ivo vachiri vashoma kune chakadaro chikamu chemazuva ese, asi ivo vari kuoneka. EPD hazvireve kuti chigadzirwa chakasvibira, asi chinomanikidza kubuda pachena nezvezvinokonzeresa kubva pamubhedha kuenda kugedhi. Inobvumira kuenzanisa kwechokwadi. Dzimwe nguva, chigadzirwa kubva muhombe, yakabatanidzwa fekitori munzvimbo yakaita seYongnian District inogona kuve nekushomeka kwakaderera pachikamu nekuda kwehukuru uye kugona, zvichienzaniswa nediki mugadziri wemuno achishandisa nzira shoma. Inopesana nemasikirwo ekutenga chete geographically pedyo.

Iyo yekurongedza ndeimwe musoro. Magasi anotakurwa kubva mhiri kwemakungwa anowanzouya akaputirwa nepurasitiki pamapuranga emapuranga. Takatanga kukumbira-uye dzimwe nguva tichibhadhara mari ye-pepa-based packaging uye mapallets akabatanidzwa. Inhanho diki, asi kana makondirakiti akakwana achiida, inochinja maitiro. Webhusaiti yezitai Fasteners (https://www.zitafornasteers.com) inoratidza kugona kwavo, asi izvo zvakatipoteredza ndizvo zvaunoda kuongorora mukutaurirana kwakananga.

Ramangwana: Biopolymers uye Smarter Dhizaini

Ndiri kuchengeta ziso pane biopolymer-based gaskets. Zvinhu zvakatorwa kubva muchibage cheindasitiri kana zvimwe zvipenyu. Dzidziso yacho yakakura: renewable sosi, inogona compostable pakupera-kwehupenyu. Asi dhiyabhorosi ari mune zvakadzama. Ivo vanobata sei kuratidzwa kweUV isati yaiswa? Ndeipi yavo yenguva refu yekumanikidza yakaiswa kana ichienzaniswa neyekugadzira? Isu takaedza prototype; yaiita zvakanaka munzvimbo dzakapfava asi yakava brittle mukutonhora kwakanyanya. Iyo tekinoroji haina kugadzirira yekutanga nguva, asi igwara chairo. Kiyi ichave ichifananidza mabhenji ekuita eakanakisa ekugadzira iwo.

Smarter dhizaini yekubatanidza ndiyo imwe muganhu. Sei gasket iri chikamu chakasiyana? Zvakadini kana basa rekuisa chisimbiso rakabatanidzwa mundiro yepasi pachayo, kana mugadziriro yenheyo yakagadzirwa? Izvi zvinobvisa kucheka tsvina uye kukanganisa kuisa. Mamwe masisitimu edzimba dzekuEurope ari kufamba nenzira iyi. Zvinoda shanduko yehurongwa mukuvaka kwatinoita, kwete kungochinjanisa chikamu.

Saka, kukanganisa kwezvakatipoteredza kwe zvinhu zvakarurama sill ndiro gasket iri multi-variable puzzle. Haisi nyore zvinhu izvi zvakanaka, izvo zvinhu zvakaipa. Iri nezve yakamisikidzwa kabhoni, kushandiswa kwesimba rekuchengetedza, kusimba, kugadzirwa kwemarara, uye tsika dzekutengesa. Sarudzo yakanyanya kusimba kazhinji ndiyo yaunoisa kamwe chete uye usambofunga nezvazvo zvakare-nekuti iri kuita basa rayo zvakakwana kune hupenyu hwechivako. Ndiyo tarisiro chaiyo, uye kusvika ikoko kunoda kutarisa kupfuura kushambadzira uye mune gritty ruzivo rwechemistry, fizikisi, uye chaiyo-yepasirese kuvaka zvinhu.
