Iintsingiselo zemarike yegasket yefestile? 

Iindlela zeMarike yeGasket yefestile: Umbono woMsebenzi osuka kuMgangatho

Wonke umntu uthetha ngezinto ezintsha kunye nokuzinza, kodwa ukuba ubufuna okanye ukhankanya irhasi yefestile okwethutyana, uyazi ukuba ibali lokwenyani lihlala limalunga nokuhanjiswa kwezinto, izinto ezingahambi kakuhle kwikhonkco lonikezelo lwengingqi, kunye nomsantsa ophazamisayo phakathi kwedatha yokusebenza kwelebhu kunye neyona nto isebenzayo kwindawo ephezulu kwisixeko esiselunxwemeni. Umkhwa awukho nje uluhlu lweepolymer ezintsha.

I-Raw Material Squeeze ayiyo le nto ucinga ngayo

Ewe, i-EPDM kunye ne-TPV zisengookumkani, kodwa ukuguquguquka kweendleko akukona nje ngamaxabiso eoli. Imalunga nokuhambelana kwekhompawundi. Sineprojekthi kulo nyaka uphelileyo apho ibhetshi ye-gasket evela kumthengisi ohloniphekileyo yasilela kwiimvavanyo ezisisiseko zokuxinzelela. Umoni? Umxholo we-EPDM ohlaziyiweyo awuzange uguquke nje; umthombo womthombo wawungahambelani-ngamanye amaxesha ukusuka kwizitywina zeemoto, ngamanye amaxesha ukusuka kwimibhobho yokuphahla. Umthengisi uye wadibana negatya lomxholo osetyenzisiweyo kodwa uphose ngokupheleleyo inkcazo yokusebenza. Intsingiselo ngoku ibhekiselele kwimisinga enokulandeleka esetyenziswe ngokutsha, hayi nje ipesenti ephepheni.

Oku kutyhala abathengi ukuya kubavelisi abadityanisiweyo abalawula ngaphezulu komxube wabo oxubeneyo. Ndicinga ngeefemu ezikwiindawo ezinkulu zemveliso, ezifana nezo zikwiSithili sase-Hebei saseYongnian, isibophelelo esikhulu kunye nesiseko secandelo lokutywina. Inkampani efana I-Sunnian Zitai Festener Fishaner Comment Com., esebenza ukusuka kuloo mmandla, ingumzekelo woncedo lweziseko ezingundoqo. Ukuba kufuphi noololiwe abakhulu kunye nothungelwano lweendlela kuthetha ukuba abenzi nje iinxalenye; bakwindawo yokulawula ukungena kwemathiriyeli ekrwada kunye nokuphuma kwempahla egqityiweyo ngexabiso elifanelekileyo, iifektri ezisasazekileyo ezincinci, ezisasazekileyo ziyasokola ukuhambelana. Kuba i-perket yefestile abathengi, lo mqolo wolungiselelo uba yinto ebalulekileyo yokukhetha, njengoko uchaphazela ngokuthe ngqo amaxesha okukhokela kunye nokusebenza komyalelo wesambuku.

Eyona nto intsha kwimathiriyeli inobuqili. Kukwii-hybrid seals-ezifana nomzimba we-TPV onomlomo we-silicone othambileyo wokucima ukutywinwa-ejongene neendawo ezithile zentlungu ezifana ne-ultra-fine dust ingress kwi-desert builds okanye ukuxhathisa ityuwa. Ayizozinto eziphuma kwishelufu okwangoku; bafuna incoko ethe ngqo kunye neqela lobunjineli bomenzi.

Iinyani zoFakelo eziLawula uTshintsho loYilo

Nantsi inguqu enkulu, engaxoxwanga phantsi: iiprofayili zegasket zenza lula. Uyilo oluntsonkothileyo, olunamagumbi amaninzi lweminyaka yoo-2000s lukhangeleka lukhulu kwiikhathalogu kodwa ngamaphupha amabi abafakeli. Ukungalungi kakuhle ngexesha lokufakwa kwefestile kuqhelekileyo, okukhokelela ekungaphumelelini koxinzelelo ngokukhawuleza kunye nokufowunelwa.

Intsingiselo ibhekiselele ekuxoleleni ngakumbi, rhoqo kusekwe kwibhalbhu, iiprofayili ezinonyamezelo oluphezulu lokwahluka kwesakhelo sesakhelo. Sibona ukubuyela ekusebenzeni. Ukusebenza akuphunyezwanga nje ngobume beprofayili, kodwa ngolawulo olungcono, olungaguquguqukiyo lwe-durometer kunye nonyango lwangaphezulu olunciphisa ukukhuhlana ngexesha lofakelo. I-gasket ephazamisayo kunye ne-twist ngexesha lokufakwa ayinamsebenzi, kungakhathaliseki ukuba yiyiphi imilinganiselo yemozulu.

Kulapho inkqubo yokuvelisa ngokwayo ingumkhwa. I-extrusion engaguqukiyo, i-vulcanization echanekileyo (yeekona ezicandiweyo), kunye nokucoceka, ukusika okungenayo i-burr ngoku kukhuphisana. Ayisiyonto intle, kodwa yeyona nto ithintela ukuvuza komoya kunye namanzi. Iinkampani ezinamava anzulu kwizibophelelo zentsimbi ezichanekileyo, umzekelo, zihlala zizisa olo qeqesho kwi-polymer extrusion. Ingqondo ejikeleze ukunyamezela ukudluliselwa.

Umbuzo woZinzo: Ngaphaya kwaMabango okuThengisa

Iigaskets eziluhlaza yindawo yemigodi. Ii-TPE ezisekelwe kwi-Bio zivakala zithembisa, kodwa ezininzi zisanqongophala ixesha elide le-UV kunye nokuzinza kwe-thermal yewaranti yefestile ye-20 yeminyaka. Olona qheliselo lukhulu oluzinzileyo ngoku alukho kwizinto eziphathekayo ngokwazo, kodwa ekuphuculeni inkqubo yokunciphisa inkunkuma-zombini ekuqhutyweni kwemveliso nakwindawo.

Sasebenza kunye nomvelisi owatshintshela kumthengisi onikezela kwangaphambili, iikiti ezinqamlekileyo zekona kwiimodeli ezithile zefestile, kunokuthenga iireli kunye nokusika kwisayithi. Inkunkuma yempahla yehle phantse nge-18%. Umkhwa lolu hlobo lonikezelo lwexabiso lobunjineli. Ukuzinza kwavela ekusebenzeni, kungekhona nje kwifomula entsha yepolymer.

Ukuphela kobomi kuhlala kungumba onzima. Ukuphinda kusetyenziswe okwenyani kweerubha ze-thermoset njenge-EPDM kulinganiselwe. Ishishini lijonge ukuphuhliswa kwe-thermoplastic vulcanizates (TPVs) kunye ne-olefin block copolymers enokuthi iphinde iphinde iqhutywe kwakhona. Kodwa ukuqokelela kunye nokuhlelwa kweziseko zophuhliso lweegaskets zokudiliza azikho kwinqanaba. Okwangoku, elona bali lithembekileyo lokuzinza lihlala ixesha elide-lichaza i-gasket edlula ubomi benkonzo obulindelweyo befestile.

Imigangatho yeNgingqi kunye ne-Global Sourcing Puzzle

Awukwazi ukuthetha iintsingiselo ngaphandle kokuvuma iBalkanization yemigangatho yokusebenza. Igasket edlula kuMntla Merika i-AAMA 701/702 isenokungahlangani noxinzelelo oluguquguqukayo lovavanyo lokuhamba ngebhayisikile olufunekayo kwiimarike ezithile zaseYurophu. Intsingiselo yabavelisi behlabathi kukugcina iipotfoliyo zezatifikethi ezininzi, nto leyo ebaluleke kakhulu.

Le yenye indawo apho iziseko zemveliso ezinkulu zibonisa amandla azo. Umenzi onobukho obuninzi bemarike yasekhaya, njengalowo usekwe kweyona ndawo inkulu yaseTshayina isiseko semveliso eYongnian, eHandan, uhlala enomthamo kunye namandla obuchule okuqhuba imigca yemveliso eyahlukeneyo okanye ukwahlula ngokungqongqo iikhompawundi zezatifiketi ezahlukeneyo zengingqi. Iwebhusayithi yabo, I-Zitafasteners.com, ngelixa kugxilwe kwiifasteners, iingcebiso kwesi sikali samandla. Kuba i-perket yefestile umthengi, ukuqinisekisa oku kuthotyelwa kwemigangatho emininzi ngundoqo kwiiprojekthi ezijolise kumazwe angaphandle.

Intloko ebambekayo kukulawula oku kwikhonkco lakho lokubonelela. Kuthetha amaxwebhu ebhetshi angqongqo ngakumbi kwaye okunokubakho kabini-ukufumana iiprojekthi kwiijografi ezahlukeneyo. Ingcinga yokuba i-gasket enye ilingana nazo zonke iimarike zehlabathi iya iphela ngokukhawuleza.

Umsonto weDijithali: Ukusuka kwi-BIM ukuya kuLondolozo lweNdawo

Oku kuyavela, kodwa kuyinyani. Abacacisi abangakumbi bacela izinto ze-BIM kwiiprofayili ze-gasket, hayi nje ukubonwa, kodwa uhlalutyo lwebhulorho eshushu kunye nobude obuchanekileyo bokuthatha. Umkhwa ubhekiselele kwiigaskets njengenxalenye yedatha-rich.

Sizama iikhowudi ze-QR ezifakwe kwi-laser kwikhava ye-splice okanye iithegi ze-reel. Xa beskeniwe, batsala idatha yedatha, ukufakwa kwevidiyo yaloo profayile ethile, kunye nengxelo yovavanyo lwebhetshi yasefektri. Imalunga nokuvala iluphu yolwazi phakathi komenzi, umfaki, kunye nomphathi weziko lexesha elizayo. Injongo kukuguqula i-gasket ukusuka kwimpahla yorhwebo ibe yinkqubo yolwakhiwo ebhaliweyo, elandelekayo.

Oku akukaxhaphakanga okwangoku, kwaye yongeza iindleko. Kodwa kwiiprojekthi ezintsonkothileyo, ezinexabiso eliphezulu, ukukwazi ukuphicotha yonke inkqubo yokutywina kuba yindawo yokuthengisa. Ijika i-gasket ethobekileyo ibe yi-asethi elawulwayo. Abavelisi abaya phambili baya kuba ngabo imveliso yabo kunye neenkqubo ze-IT ezinokuxhasa eli nqanaba lokulandelela umgangatho wento ngaphandle kokukhubazeka ngaphezulu.
