Eyona gasket engamanzi ukuzinza? 

Xa usiva i-gasket yolwelo oluzinzileyo, uninzi lwabantu ngokukhawuleza lutsibela kumxholo we-VOC okanye mhlawumbi izinto ezihlaziyiweyo kwityhubhu. Le yinxalenye yayo, ngokuqinisekileyo, kodwa ukuba ubutywina iiflange ebaleni kangangexesha elithile, uyazi ukuba yincam nje ye-iceberg. Umbuzo wokwenene wokuzinza awukho nje malunga neleyibhile eluhlaza kwi-shelf; imalunga nento eyenzekayo emva kokuba uyifakile. Ngaba iyahlala? Ngaba iyasilela kwangaphambi kwexesha kwaye ibangele ukuvuza, ichithe lonke ulwelo obekumele iluqulathe kwaye idale ubugqwirha obungaphezulu kokusingqongileyo kunokugcinwa kwemveliso? Ndiyibonile loo nto isenzeka amaxesha amaninzi ukubala.

Ukuchaza uZinzo kwihlabathi elinobumdaka

Masiyiqonde le nto. Kumgca wethu womsebenzi, ukuzinza kufuneka kubandakanye ukuqina. I-gasket ephilisa ngokugqibeleleyo kodwa ithotywa kwiminyaka emibini phantsi kwebhayisikile ye-thermal ayizinzile, nokuba yenziwe kwiimbotyi zesoya eziphilayo. Ujonge i-total do-over, oko kuthetha ukuba izinto ezininzi, umsebenzi othe kratya, amandla angaphezulu, kunye nomngcipheko wongcoliseko oluvela kumajelo avuzayo. Ngoko umgaqo wam wokuqala uhlala ukusebenza kwexesha elide. Ngaba inokumelana noxinzelelo oluthile-inokuba bubushushu, uxinzelelo, okanye ukuvezwa kweekhemikhali-kubomi obucetyiweyo bendibano?

Emva koko kuza ukuqulunqwa. I-VOC ephantsi, i-silicones engena-solvent (njenge-Permatex Ultra Black) okanye i-anaerobic flange sealants (njenge-Loctite 518) ziindawo zokuqala eziqhelekileyo. Kodwa i-solvent-free ayithethi ngokuzenzekelayo ukuba ngcono kwiplanethi. Kufuneka ujonge umjikelo wobomi uphela. Ingaba ingakanani amandla emveliso yayo? Ndikhumbula iprojekthi apho siye sachaza i-silicone eluhlaza, kodwa safumanisa ukuba ukupakishwa kwayo yayiyiplastiki eninzi engenakuphinda isetyenziswe. Kwaba ngathi siyiphosile inqaku ngokupheleleyo.

Kwaye kukho inkunkuma yesicelo. Eyona tyhubhu ezinzileyo yileyo onokuthi ukhuphe ngokupheleleyo ngaphandle kwesiqingatha sayo solusu phezu komlomo okanye ufuna umpu okhethekileyo ongasokuze uphinde uwusebenzise. Ndingqiyama kwiikhatriji ezinamatywina aqinileyo kunye nemigqomo ecacileyo. Uyabona okuseleyo, uyisebenzise yonke.

UZinzo vs. Ukususwa kweTrap

Olu lurhwebo lwakudala. Itywina elisisigxina ngokwenene, elinamandla aphezulu lihlala lithetha iphupha elibi xa liqhaqha. Uyacofa, uyakrwela, uyasila-uvelisa inkunkuma ethile kwaye unokonakalisa iindawo zokukhwelana, ezithi ke zifune ukwenziwa ngoomatshini okanye ukutshintshwa. Luphi uzinzo kuloo nto?

Kunxibelelwano olusebenzisekayo, i-medium-strength, form-in-place gasket (FIPG) ehlala ithambile okanye eyenzelwe ukucandeka ngokucocekileyo idla ngokuba lolona khetho luzinzileyo. Iimveliso ezifana ne-ThreeBond 1215 okanye ezinye ze-silicones ze-RTV ezinokubambelela kakuhle kodwa i-peel elawulwayo inokwandisa ubomi bamacandelo angaphantsi. Ndifunde oku kabuhlungu kwizindlu zempompo. Isetyenziselwe i-ultra-high-strength anaerobic. Kwiminyaka emihlanu kamva, ngexesha lolungiso, sachitha iiyure kwaye senza iimfumba zothuli oluyingozi oluyingozi lusahlukana. Izindlu zanikwa amanqaku. Sigcine kwisitywina sokuqala kodwa sidale inkunkuma eyongezelelekileyo ezantsi komsinga.

Isitshixo sihambelana namandla e-sealant kwixesha lenkonzo. Isixhobo esisisigxina? Hamba ngamandla aphezulu. Ngaba kukho into evulwa rhoqo emva kweminyaka embalwa ukuze ihlolwe? Beka phambili ukususwa okucocekileyo. Le ndawo yesigqibo kulapho impembelelo yokwenyani yokusingqongileyo ilawulwa khona, kude neencwadana zokuthengisa.

IiNyinene ezikwiSiza kunye noLungiselelo loMboneleli

Nantsi i-engile esebenzayo ehlala ingahoywa: indawo yekhabhoni yobonelelo. Ukuba u-odola izitywini ezikhethekileyo ukusuka kwisiqingatha sehlabathi kuwo wonke umsebenzi, ikhowudi eluhlaza yemveliso ngokwayo iyancitshiswa kuthutho. Yiyo loo nto ngamanye amaxesha ndijonge kufutshane nekhaya. Umzekelo, xa ukhangela iziqhoboshi ezisemgangathweni kunye nezisombululo ezinxulumene nokutywinwa kweeprojekthi ezinkulu zemizi mveliso e-Asiya, ukusondela kwimiba yee-hubs. Inkampani efana I-Sunnian Zitai Festener Fishaner Comment Com., ebekwe kweyona siseko sikhulu somgangatho wemveliso yaseTshayina e-Yongnian, ekufuphi noololiwe abakhulu kunye nothungelwano lweendlela ezinkulu, ngumzekelo wolungiselelo olusebenzayo. Ngelixa zaziwa ngezibophelelo, umgaqo wazo wokusebenza-ukunciphisa umgama wokuhamba kunye nobunzima-yinto ekufuneka iqwalaselwe ngabacacisi betywina. Umsebenzi ozinzileyo awukho nje ikhemistri kwi-tube; yindlela le ityhubhu ifika ngayo kwivenkile yakho. Ungajonga useto lwabo lolungiselelo apha https //wwww.ziitasteners.com ukuqonda iziseko ezingundoqo ezixhasa amakhonkco obonelelo ngengingqi.

Inqaku leNxibelelo: Umsebenzi wokukhupha i-High-Temp

Akukho nto ivavanya amabango azinzileyo e-sealant njenge-exhaust manifold. Imijikelo yobushushu ikhohlakele, kwaye ukungaphumeleli kuthetha ukukhutshwa okuthe ngqo. Sivavanye ii-RTV ezimbalwa zobushushu obuphezulu. Omnye wasilela ngokuba brittle kunye nomgubo emva kweenyanga ezimbalwa. Enye ibanjwe kodwa kwakungenakwenzeka ukuyisusa ngaphandle kokonakalisa i-manifold ngexesha lokubuyisela.

Ophumeleleyo, kulungiselelo lwethu oluthile, uye wajika waba ngumenzi othile we-silicone gasket efakwe ngobhedu. Ayizange ithengiswe njengeyona iluhlaza, kodwa ixesha elide lithetha ukuba siphephe izicelo ezithathu kwakhona ebomini bovavanyo lokuthelekisa. Oko kwasindisa izinto, umsebenzi kunye nexesha lokuphumla. I-copper filler iphucule i-thermal conductivity, enokuthi yanceda i-joint ukulawula uxinzelelo lobushushu ngcono. Sifunda ntoni? Ngamanye amaxesha, isongezelelo esonyusa ukusebenza ngokungathanga ngqo sikhulisa uzinzo ngokuthintela ukusilela kwangoko.

Awuyi kuyifumana le datha. Kuya kufuneka ulandelele ukusebenza ngexesha, apho uninzi lweevenkile ezingenayo i-bandwidth yazo. Yingakho amava entsimi ekwabelwana ngayo eyigolide.

I-Biodegradability: I-Niche, hayi i-Panacea

Kukho iisealants ezimbalwa ezisekwe kwibhayoloji ezivelayo. Amava am alinganiselweyo kukuba banendawo yabo-mhlawumbi kwi-low-stress, izicelo ezifikeleleka ngokulula apho ufuna ukuba zithobe ukuze kube lula ukuchithwa kwexesha elizayo. Kodwa ngokutywinwa okubalulekileyo, ndiyathandabuza. Indawo yokusebenza (ubushushu, i-oyile, i-coolant) kaninzi ayihambisani ne-biodegradation elawulwayo eyilelwe.

Ndazama enye kwizindlu zempompo zamanzi kwi-rig non-critical test rig. Ivalwe kakuhle ekuqaleni, kodwa sabona ukulila kancinci emva konyaka kwindawo efudumeleyo nefumileyo. Kwakubonakala ngathi ilahlekelwe yingqibelelo. Ngaba yayikukonakaliswa kwezinto eziphilayo? Ingayiyo. Ayisiso isiphumo oyifunayo sempompo. Ke, ngelixa lithembisa, de itekhnoloji ihambelane nokuqina kwe-synthetics esekiweyo, igalelo layo elizinzileyo likhawulelwe kumatyala athile, angekho baluleke kakhulu.

Inguqulelo entsha iyonwabisa, kodwa ayiyonto yokulahla. Ukanti.

Isigqibo? Yinkqubo, hayi iMveliso

Ke, akukho mveliso enye. Yindibaniselwano yezinto. Okokuqala, khetha i-chemistry efanelekileyo (i-silicone, i-anaerobic, i-polyester) kwiimfuno zobugcisa bomsebenzi-leyo isiseko sakho sokuqina. Okwesibini, ngaphakathi kwelo candelo, khetha uphawu oluthembekileyo olune-VOC ephantsi, ukupakishwa okusebenzayo. Okwesithathu, kwaye okona kubaluleke kakhulu, kusetyenziswe ngokuchanekileyo. Imveliso egqibeleleyo esetyenziswe kakubi yinkcitho eyi-100%.

Olona qheliselo luzinzileyo endilwenzileyo kukucwangciswa komphezulu wokulungisa kunye nokusebenzisa eyona ntsimbi ibhityileyo, eqhubekayo efunekayo. Ukusetyenziswa ngokugqithisileyo akwenzi itywina elingcono; yenza nje ukukhama, okuyinkunkuma emsulwa, kwaye kunokubangela ukuvaleka kwangaphakathi kwiipaseji zolwelo. Ndigcina ugcino lwento esebenzayo apho: i-anaerobic yeeflange zoomatshini, i-RTV ethile yamakhava anesitampu, iFIPG yeendawo ezingalinganiyo.

Ekugqibeleni, esona sixhobo sizinzileyo sinokuba ngamava okwazi ukuba yeyiphi i-sealant omawuyisebenzise, ingakanani, kwaye ulindele nini ukuba iphinde yahlukane kwakhona. Olo lwazi lunqanda inkcitho engaphezulu kunayo nayiphi na imveliso eco-friendly enokuthi ibenakho. Kumalunga nokwakha izinto eziya kuhlala zihleli, kwaye zinikwe inkonzo, kunye nokurhawulwa okuphindaphindiweyo kokusingqongileyo kangangoko kunokwenzeka. Yonke enye into ziinkcukacha nje.
