Xa usiva impembelelo yokusingqongileyo kunye ne-sill plate gasket kwisivakalisi esifanayo, abaninzi abantu abathengisa ngokukhawuleza bacinga ngezinto eziphathekayo-ngokuqhelekileyo i-foam evaliweyo okanye irabha. Kodwa loo nto ingaphezulu nje. Ibali lokwenyani, eyona nto ibalulekileyo kwindawo yomsebenzi kwaye ekuhambeni kwexesha, limalunga nomjikelo wobomi bonke: ukusuka kwisuphu yekhemikhali esetyenziswa kwimveliso, ukuya kwindawo efanelekileyo kunye nobomi obude obunqanda ukuvuza kwamandla, ukuya kuthi ga kwi-scrap oshiywe uyibambe ekupheleni kokufakela. Akukhona nje malunga nokuba yinto eluhlaza, malunga nokuba yiyona izinto ezifanelekileyo ngenxa yomsebenzi ukuze ungabi yinkcitho kwiminyaka emihlanu.

Ukubunjwa kwezinto eziphathekayo: Ngaphezulu kwegwebu nje

Makhe sicacise. Iigaskets ezininzi, ngakumbi ezo zingabizi kakhulu, zisebenzisa i-EPDM okanye i-PVC exutywa neplastiki. Ezi zongezo zezona zinto zinika ukuguquguquka kwezinto, kodwa ziyakwazi ukuphuma kwi-gas volatile organic compounds (VOCs). Ngosuku olushushu, ukutywina i-sill plate, ngamanye amaxesha unokuvumba-loo nto inqabileyo, iphunga lekhemikhali. Asinto nje engathandekiyo; luphawu lwento ephumayo. Ndikhe ndabona izinto ezifuna ukutywinwa kwe-VOC ephantsi kodwa emva koko zibhanqe kunye ne-gasket eyona nto ikhupha i-gassing plasticizers, ijongela phantsi wonke umzamo. Izinto ezifanelekileyo apha azikho ixesha lokuthengisa; imalunga nokufumana ibhalansi phakathi kokuqina kunye nokungangeni. Eminye imixube emitsha ye-thermoplastic polyolefin ibonakala ithembisa-i-off-gassing encinci, i-compression compression set resistance-kodwa ixabisa ngaphezulu. Ngaba inzuzo yokusingqongileyo ixabisa indleko yangaphambili? Lolo lubalo lwemihla ngemihla.

Emva koko kukho i-carbon footprint yemveliso. Apha kulapho iingxoxo ezininzi eziqhelekileyo ziphela khona. Kodwa emva kokundwendwela iifektri, njengee-fasteners zemveliso e-Hebei, e-China, uyawubona umlinganiselo. Inkampani efana I-Sunnian Zitai Festener Fishaner Comment Com., esebenza kwisiseko esikhulu semveliso, inesiseko sokufumana imathiriyeli ekrwada ngokufanelekileyo kwaye inokunciphisa inkunkuma kwiinkqubo zokubumba. Indawo yabo kufuphi neendlela ezinkulu zokuthutha ezifana neBeijing-Guangzhou Railway kunye neBeijing-Shenzhen Expressway ayikho nje indawo yokuthengisa; kunciphisa ukukhutshwa kwezithuthi zokuhambisa imveliso kwizibuko. Kodwa i-flip side yindleko yendalo yendawo yokwenziwa kwemveliso. Yinxaki entsonkothileyo uninzi lwabasebenzisi bokugqibela abakhe bayibone.

Sizame i-100% ye-rubber gasket esetyenzisiweyo kwiprojekthi malunga neminyaka emibini edlulileyo. Ingcamango yayigqibelele: vala i-loop, sebenzisa amatayara enkunkuma. Inyaniso yayiliphupha elibi. Isethi yokunyanzeliswa yayiyoyikeka-ayizange ibuye emva kokuba iplate ephantsi ifakwe phantsi. Ngexesha elithile, saba nemiba yokungena emoyeni. Injongo yokusingqongileyo yayilungile, kodwa imveliso yasilela kumsebenzi wayo ophambili: ukutywina. Oko kusilela kuthetha ukusetyenziswa kwamandla aphezulu kwisakhiwo kunye nokwenza kwakhona ngokupheleleyo, ukuvelisa inkunkuma eninzi. Ngoko ke, eyona nto ibonakalayo yokusingqongileyo ngamanye amaxesha yeyona igcina ubomi besakhiwo.

Iinyani zoFakelo kunye neNkunkuma Stream

Akukho mntu uthetha ngenkunkuma ekwisiza. Iigaskets ziza ngemiqulu okanye imicu. Ulinganisa, unqumle. I-off-cuts? Bangena kwi-dumpster. Kwiprojekthi enkulu yorhwebo, leyo ingaba neengxowa ezininzi ze-foam okanye i-rubber scrap. Ayinabungozi, ngoko iya kwindawo yokulahla inkunkuma. Saqala inkqubo yokulingwa kunye nomthengisi omnye ukuze sibuyise izinto ezicocekileyo ukuze zisetyenziswe kwakhona, kodwa ulungiselelo lwayibulala. Iindleko zokuthumela ngenqanawa ngokukhululekileyo, i-bulky foam scraps ukubuyisela kwindawo yoncedo ngaphezu kwayo nayiphi na inzuzo. Ibonise umsantsa omkhulu: uyilo lwemveliso yokuphela kobomi. Ukuba iigaskets zeza ngobungakanani beemodyuli ezingaphezulu okanye ngenkqubo yokubuyisela ebhakwe kwisixokelelwano sobonelelo, njengabanye abavelisi baphonononga ngokupakisha, inokutshintsha izinto.

Enye impembelelo efihliweyo yi-adhesive. Iigasket ezininzi ze-sill seal zine-peel-and-stick backing. Loo maleko ancamatheleyo idla ngokuba yimveliso yepetrochemical. Ukuba i-gasket idinga ukutshintshwa (kwaye bayasilela), ushiywe kunye nentsalela encamathelayo kwisiseko sekhonkrithi esisisilwanyana sokususa, esihlala sidinga i-solvents yamachiza. Siye safudukela ekusebenziseni i-gaskets yoxinzelelo-kuphela apho kunokwenzeka, sixhomekeke kumthwalo we-fastener ukutywinwa. Iphelisa umjelo wenkunkuma encamathelayo ngokupheleleyo. Ifuna ukuchaneka ngakumbi ngexesha lokuqulunqa kunye nokuqinisa, kodwa yinkqubo ecocekileyo.

Ndikhumbula i-retrofit apho kwafuneka sisuse iigaskets ezindala, ezonakeleyo zogwebu. Zazidilika zaba ngamawaka amasuntswana amancinane. Ukuziqulatha kwaba ngumbhodamo. Yayingeyotyhefu, kodwa yayilungcoliseko lwe-biodegradable. Loo mava andenze ndaligqwetha elinamandla lokujonga iprofayili yokuthotywa kwezinto. Ngaba iya kuguquka ibe yi-microplastics emhlabeni kwiminyaka engama-30? I-polyethylene edibeneyo yeseli evaliweyo inokwenza ngcono apha kunegwebu elivulekileyo leseli elifunxa amanzi kwaye liqhekeke ngokwasemzimbeni.

Ukusebenza yeyona nto ibalulekileyo: i-Energy Link

Eyona mpembelelo inkulu yokusingqongileyo a I-SIR PLAIT ayisiyokwenziwa kwayo, kodwa ukusebenza kwayo kwindawo. Igasket engasebenzi kakuhle ikhokelela ekuvuzeni komoya. Ukuvuza komoya kuthetha ukuba inkqubo yeHVAC yesakhiwo isebenza nzima. Oko kunyuswa kokusetyenziswa kwamandla, kumashumi eminyaka, kunciphisa ikhabhoni efakwe kwi-gasket material ngokwayo. Ndenze uphononongo lokucinga nge-thermal kwizakhiwo apho i-sill seal yayilikhonkco elibuthathaka-ungabona ibhulorho eshushu icace njengemini. Ukukhetha izinto ezifanelekileyo sisicwangciso sokugcina amandla kuqala.

Apha kulapho ubukhulu, ukuxinana, kunye nesantya sokubuyisela kubalulekile. I-gasket ebhityileyo kakhulu okanye enokubuyiselwa kakubi phantsi komthwalo ozinzileyo iya kudala umsantsa. Ndikhetha iigaskets ezinepesenti ephezulu yokubuyisela (njenge-90% +). Babiza ngaphezulu, kodwa bagcina itywina nangona ukhuni luyancipha okanye luhlala kancinci. Olo kunyaniseka kwexesha elide kukuphumelela kokusingqongileyo. Kuyadanisa xa ubunjineli bexabiso busika i-gasket spec ukugcina i-0.50 yeedola ngonyawo lomgca, okunokuthi kubize amawaka amandla alahlekileyo.

Kukho unxibelelwano kunye nezinye izixhobo. Umzekelo, iipleyiti ze-sill eziphathwa ngoxinzelelo zinokuba nomxholo ophezulu wokufuma. Ezinye izinto ze-gasket azihambelani kwaye zinokunciphisa ngokukhawuleza xa zidibana rhoqo kunye nezigcini ezithile. Udinga imathiriyeli engasebenzi ngokwekhemikhali kwindawo ethile. Yinkcukacha encinci, kodwa ukuyifumana ingalunganga kukhokelela ekungaphumelelini kwangaphambi kwexesha kunye nayo yonke inkunkuma ehambelanayo kunye nezohlwayo zamandla.

Ikhonkco lonikezelo kunye neNdlela yokuziphatha yoMveliso

Xa uvelisa izinto ezifana neziqhoboshi okanye iigaskets kumvelisi omkhulu, uthenga kwiindlela zabo zokusingqongileyo. Umenzi othanda Handan Zitai Fastener idwelisa uthutho olululungeleyo njengenzuzo engundoqo. Ukusuka kumbono wokubalwa kwekhabhoni, ulungiselelo olusebenzayo luyinxalenye yokwenyani yokunciphisa unyawo lwemveliso. Kodwa kufuneka ubuze nzulu: kuthekani malunga nenkqubo yabo yokucoca amanzi? Umthombo wamandla koomatshini babo bokubumba? Ngaba basebenzisa umxholo ohlaziyiweyo kwi-polymer feedstocks? Le ayiyomibuzo oyifumanayo iphendulwe kwiphepha elimiselweyo; kufuneka ugrumbe, okanye ngcono okwangoku, uphicotho.

Siye satshintshela ezinye izinto kubaboneleli abanokubonelela ngeqela lesithathu leZibhengezo zeMveliso yokuSingqongileyo (EPDs). Zisenqabile kwicandelo elinjalo, kodwa ziyabonakala. I-EPD ayithethi ukuba imveliso iluhlaza, kodwa inyanzelisa ukungafihli malunga neempembelelo ukusuka kwimbeleko ukuya esangweni. Ivumela uthelekiso lokwenene. Ngamanye amaxesha, imveliso evela kumzi-mveliso omkhulu, odibeneyo kwindawo efana neSithili saseYongnian unokuba nefuthe eliphantsi kwiyunithi nganye ngenxa yesikali kunye nokusebenza kakuhle, xa kuthelekiswa nomvelisi omncinci wendawo usebenzisa iindlela ezingaphantsi. Ichasene nethuku lokuthenga nje ngokusondeleyo ngokwejografi.

Ukupakishwa yenye intloko ebuhlungu. Iigesi ezithunyelwa ngenqanawa zisuka phesheya zidla ngokuza zisongelwe ngeplastiki enzima kwiipalethi zomthi. Siye saqala ukucela-kwaye ngamanye amaxesha sihlawula iprimiyamu yokupakishwa kwephepha kunye neepaliti ezidityanisiweyo. Linyathelo elincinci, kodwa ukuba iikontraka ezaneleyo ziyayifuna, itshintsha indlela yokuziqhelanisa. Iwebhusayithi yeZitati Fasteners (https //wwww.ziitasteners.com) ibonisa isakhono sabo, kodwa iinkcukacha zokusingqongileyo zezona zinto kufuneka uziphonononge kunxibelelwano oluthe ngqo.

Ikamva: IBiopolymers kunye noYilo olukrelekrele

Ndibeka iliso kwi-gaskets esekwe kwi-biopolymer. Izinto ezithathwe kumbona wemveliso okanye enye i-biomass. Ithiyori ilungile: isixhobo esinokuhlaziywa, sinokuvundiswa ekupheleni kobomi. Kodwa usathana ukwiinkcukacha. Bakuphatha njani ukuvezwa kwe-UV ngaphambi kokufakwa? Yintoni isethi yabo yexesha elide yoxinzelelo xa kuthelekiswa ne-synthetics? Sivavanye iprototype; ibisebenza kakuhle kwimozulu epholileyo kodwa yaba brittle kubanda kakhulu. Itekhnoloji ayikalungeli ixesha eliphambili, kodwa yindlela elungileyo. Isitshixo siya kuhambelana nebenchmarks zokusebenza kwezona zibalaseleyo zokwenziwa.

Ukudityaniswa koyilo olukrelekrele ngomnye umda. Kutheni i-gasket iyinxalenye eyahlukileyo? Kuthekani ukuba umsebenzi wokutywina wawudityaniswe kwi-plate ephantsi ngokwayo, okanye kwinkqubo yesiseko esenziwe ngaphambili? Oku kuya kuphelisa inkunkuma yokusika kunye nempazamo yofakelo. Ezinye iinkqubo zezindlu zaseYurophu zihamba ngale ndlela. Ifuna utshintsho olucwangcisiweyo kwindlela esakha ngayo, hayi nje ukutshintshwa kwecandelo.

Ngoko ke, impembelelo yokusingqongileyo ye izinto ekunene sill ipleyiti gasket yiphazili enezinto ezininzi ezahlukeneyo. Ayisiyonto ilula le nto ilungileyo, loo nto imbi. Imalunga nekhabhoni equkiweyo, ukonga amandla okusebenza, ukuqina, ukuveliswa kwenkunkuma, kunye neendlela zokubonelela ngeenkonzo. Olona khetho luzinzileyo luhlala luyifake kanye kwaye ungaze ucinge kwakhona-kuba lenza umsebenzi walo ngokugqibeleleyo kubomi besakhiwo. Leyo yeyona nto kujoliswe kuyo, kwaye ukufika apho kufuna ukujonga ngaphaya kwentengiso kunye neenkcukacha ze-gritty zekhemistri, i-physics, kunye nolwakhiwo lwehlabathi lokwenyani.
