Umnyango gasket iintsingiselo kwimarike? 

Xa abantu bebuza malunga neendlela zemarike ye-gasket emnyango, bahlala belindele uluhlu olucocekileyo lwabaqhubi: imimiselo yokusetyenziswa kwamandla, ukuhlanganiswa kwekhaya elihlakaniphile, izinto ezintsha. Akunjalo, kodwa iphosakele ukuthungwa-iinguqu zangempela zenzeke kutyelelo lwefektri, iiprototypes ezihlulekile, kunye neengxoxo zexabiso kwibakala elithile le-EPDM. Umkhwa awukho nje ulwalathiso; linqanaba lokungqubana phakathi kwento enokwenzeka ngokwethiyori kwaye yintoni kanye etywina umnyango ebusika baseChicago okanye kwimonsoon yaseBangkok. Makhe singene kuloo nto.

Umdlalo weMpahla awukho malunga neeNgcaciso nje

Wonke umntu uthetha nge-silicone kunye ne-TPE ethatha indawo yerabha yendabuko. Amaphepha athile ayaqinisekisa. Kodwa emhlabeni, iswitshi imoshakele. Ndikhumbula iprojekthi eyenziwe ngumenzi wesixhobo esiphakathi esijolise kumgca weprimiyamu. Bafumana i-silicone yodidi oluphezulu, ehambelanayo i-parket yomnyango ukwenzela iifriji. Uvavanyo lwalugqibelele. Emva koko imveliso yevolumu yabetha. Ixesha lomjikelezo wokubumba laliyi-15% ixesha elide kune-EPDM ababeyisebenzisa ngaphambili, babulala umgca wabo wokusebenza kakuhle. Umkhwa obhekiselele kwi-silicone wema ngenxa yokuba iindleko ezipheleleyo zokubalwa kobunini azizange zenziwe ngaphambili. Intsingiselo ngoku? Akunjalo nje ukusebenza kwezinto, kodwa ukuhambelana kwenkqubo. Ababoneleli abanokuthi baphuhlise i-molds kunye neeprofayili zokunyanga bayaphumelela.

Emva koko kukho ukutyhala komxholo ohlaziyiweyo. Iibrendi zifuna ukuba amabali azinzile. Kodwa ukufumana ukusebenza okungaguqukiyo kwi-post-industrial okanye kwi-post-consumer rubber compounds kuliphupha elibi. Ndizibonile iibhetshi apho iseti yoxinzelelo iyahluka ngokugqithisileyo, ekhokelela ekungaphumeleli kwetywina lomnyango emva konyaka. Eyona ndlela yokwenyani phakathi kwabavelisi abanzulu ayinikezeli nje ukhetho oluluhlaza, kodwa ukuba nobunzulu bobunjineli obudibeneyo bokuqinisekisa ukusebenza. Lugqatso oluzolileyo, lobugcisa beengalo.

Apha kulapho iziseko zenkampani zibalulekile. Thatha umvelisi njengaye I-Sunnian Zitai Festener Fishaner Comment Com.. Ngokusekwe eYongnian, intliziyo yeshishini laseTshayina elikhawulezayo, babona utshintsho lwezinto eziphathekayo ukusuka kwelinye icala. Inzuzo yabo ayikho nje ekwenzeni i-gasket, kodwa ekulawuleni ukuhamba konke ukusuka kwi-steel stamping (kwezo ndibano ezidibeneyo ze-gasket-fastener) ukuya kwi-rubber compounding. Kubo, umkhwa obhekiselele kwizisombululo ezidityanisiweyo zokutywinwa ngumdlalo wendalo. Indawo yabo kufutshane neendlela ezinkulu zezothutho ezinje ngeBeijing-Guangzhou Railway ithetha ukuba bayakwazi ukujongana ne-in-time, ii-odolo zezinto ezixutyiweyo ezifunwa zezi ndibano zinzima. Yimpendulo ebonakalayo kumkhwa.

I-Smart Seal Hype kunye neNyaniso

Ukudibanisa izinzwa kwi-gaskets ukubona ukungaphumeleli kwetywina okanye ukuvuza kwamandla ngumxholo oshushu. Ivakala njengekamva. Kodwa ukusuka kumbono wemveliso, yintloko ethembekileyo. Sazama iprototype ene-inki eprintiweyo eprintiweyo kumlebe we-gasket. Yasebenza—de yajongana nokuxinana nokuhamba ngebhayisekile eshushu. Ayiphumelelanga kwiinyanga nje ezimbalwa. Umkhwa awukho malunga nokwenza i-gasket ikhompyutha; imalunga nokwenza ujongano oluthembekileyo nenye. Okona kuthembisa ngakumbi, umkhwa ongathandekiyo kuyilo lwe-gasket esebenza ngokugqibeleleyo kunye nezahlulo zocango ezihlukeneyo, ezomeleleyo zoluvo-ukudala inkqubo ekrelekrele, hayi icandelo elilumkileyo eliya kusilela.

Olunye ujongo lokwenyani: ixabiso. Imarike yezixhobo zombane ikhuphisana ngokukhohlakeleyo. Ukongeza idola yexabiso kwi a itywina lomnyango kwiimpawu ezihlakaniphileyo aziqalisi kwi-80% yevolumu. Olona tshintsho lokwenyani likuyilo lokwenziwa-iijiyometri eziphucula ingqibelelo yesitywina kangangokuba zinciphise umthwalo kwinkqubo yokupholisa, ngokungangqalanga zinceda ukulinganisa amandla esixhobo. Leyo yindlela enamazinyo: ubukrelekrele boyilo, hayi ubukrelekrele be-elektroniki.

Ukumiselwa ngokweNgingqi koBonelelo

Ubhubhani kunye noxinzelelo lwezelizwe aluzange luphazamise nje amakhonkco obonelelo; bayitshintsha intanda-bulumko yokuyila. Intsingiselo ibhekiselele kumaziko obonelelo ngengingqi. Ayisekho malunga nokufumana owona mthombo uphantsi kwilizwe elinye. Kumvelisi we-oveni waseYurophu, oko kunokuthetha ukukhangela iigaskets ezivela eMpuma Yurophu okanye kuMntla Afrika endaweni ye-Asia, nakwixabiso leprimiyamu ye-5-10%. Icalculus ibandakanya imithwalo, umsebenzi, kunye nomngcipheko.

Oku kukulungisa ubulunga obulindelweyo. Umthengisi wegasket eMexico osebenza kwimakethi yase-US ngoku kufuneka adibane kungekuphela nje ne-specs esebenzayo, kodwa amaxwebhu achanekileyo, ukupakishwa, kunye neeprothokholi zolungiselelo lweplanti ye-Just-In-Time e-Ohio. Umqobo ekungeneni uphezulu, kodwa izivumelwano zincangathi. Intsingiselo ibhekisa kubudlelwane obunzulu, obunentsebenziswano ngakumbi nababoneleli, hayi nje ukuthenga ngentengiselwano.

Iinkampani ezimi kwiindawo eziphambili zolungiselelo ziyaziqhelanisa. Umvelisi ofana neZitai Fastener, ekufuphi neNational Highway 107 kunye neBeijing-Shenzhen Expressway, imiselwe oku. Yabo iwebhsayithi igxininisa umlinganiselo wabo wesiseko semveliso kunye nezixhumanisi zothutho-indawo eziphambili zokuthengisa ngoku. Kumthengi wehlabathi jikelele, ayisiyobuchule babo bokukhawuleza, kodwa malunga nokukwazi kwabo ukusebenza njengendawo ethembekileyo ngaphakathi kwekhonkco lokubonelela ngengingqi yaseAsia kwiindibano ezinzima zokutywina.

Ulindelo lweNtsebenzo kwiiMeko eziBabekileyo

Thetha nayo nayiphi na injineli kwi-HVAC okanye icandelo lefriji yorhwebo. Umkhwa awukho malunga neenkcazo eziphezulu ephepheni; imalunga nokuqina okwandisiweyo phantsi kweemeko eziguquguqukayo ngakumbi. Amaziko edatha kuMbindi Mpuma, imodyuli yokugcina ebandayo kumazibuko-ezi zicelo zityhala iirhasi ngaphaya kweenkqubo zovavanyo eziqhelekileyo. Imowudi yokungaphumeleli ihlala icinezelwa phantsi komthwalo ophezulu we-thermal, umlomo othetha ukuba i-gasket ayibuyi.

Sibona imfuno engakumbi yokuqinisekiswa okuhlanganisiweyo okulungiselelweyo. Akwanelanga ukuthetha ukuba le EPDM ilungile kwi-125 ° C. Ababoneleli kufuneka babonelele ngedatha yovavanyo kwiindibano zomnyango zokwenyani phantsi kweemeko zebhayisekile. Oku kutyhala umkhwa wokwenza isicelo sobunjineli. Ababoneleli abangcono kakhulu bakha amagumbi amancinci ovavanyo afana neemeko ezikhethekileyo zabathengi. Kukongezwa kwexabiso okuphumelela ishishini.

Oku kuhambelana nesayensi yezinto eziphathekayo. Kukho ugxininiso oluhlaziyiweyo kwizongezo-i-sauce eyimfihlo kwiikhompawundi zerabha ezilwa ne-ozone, i-UV, kunye nobushushu obugqithisileyo. Utshintsho apha alubonakali kodwa lubalulekile. Ngumkhwa oqhutywa kukungaphumeleli kwentsimi, hayi ukuthengisa.

IFactor engahoywayo: Ukufakelwa kunye noNyamezelo

I-gasket egqibeleleyo inokungaphumeleli ukuba isakhelo socango esihlala kuyo asikho. Ukunyamezela ukwenziwa kwesixhobo sombane okanye ucango lwesakhiwo yinto enkulu, ehlala ingahoywa. Umkhwa endiwubonayo linyathelo eliya ekuxoleleni ngakumbi uyilo lwe-gasket-iiprofayile ezixinene kabini, okanye uyilo olunoluhlu olubanzi lokutywina. Basenokubiza imali eninzi kwizinto eziphathekayo, kodwa bawanciphisa kakhulu amabango ewaranti.

Oku kufuna intsebenziswano esondeleyo. Indlela yakudala yayikukuthumela i-gasket spec kubaboneleli abathathu kwaye ukhethe eyona iphantsi. Indlela entsha ibandakanya ukwabelana ngeemodeli ze-CAD zendibano yomnyango kunye nokuqhuba ukulinganisa kwe-FEA kuxinzelelo lwetywina. Inobuchule, iyacotha, kodwa ikhusela iintlekele. Ababoneleli abanokuzibandakanya kweli nqanaba bayahlula kwipakethi.

Ikwatshintsha into esiyithethayo ngomgangatho. Akusekho nje malunga nenxalenye yomzimba, kodwa malunga nenkxaso yobugcisa kunye nentsebenziswano yoyilo emva kwayo. Imakethi yahlulahlulwe kubathengisi begasket yempahla kunye nababoneleli bezisombululo zobunjineli. Le yokugqibela kulapho umda kunye neentsingiselo zexesha elide zisingise khona.

Ngoko, oku kusishiya phi? I imarike gasket umnyango iintsingiselo ziyadibana kuhlanganiso, ukomelela, kunye nentsebenziswano enzulu yobugcisa. Incinci malunga nesixhobo esitsha somlingo kwaye ngakumbi malunga nokwenza izinto ezisisiseko ngokugqibeleleyo kwilizwe elintsonkothileyo, elinommandla, kunye nelifunayo. Ababoneleli abaya kuphumelela ngabo baqondayo ukuba imveliso yabo ayiyona nje iqhekeza lerabha-yinto ebalulekileyo kwinkqubo ekungaphumeleli kwayo kubonakala ngokukhawuleza kumsebenzisi wokugqibela. Olona xinzelelo lokwenyani, kunye nentsingiselo yokwenyani.
