Foam cork flange gasket: eco-friendly innovation? 

Mumamva ng'anjo ya thovu ndi eco-wochezeka kuponyedwa palimodzi masiku ano. Zimakupangitsani kudabwa ngati ndikupita patsogolo kwakuthupi kapena kutsatsa kwina. Nditapeza ndikuyesa izi pazogwiritsa ntchito zosiyanasiyana za flange, nditha kunena kuti zenizeni ndizovuta kwambiri. Sichipolopolo chamatsenga, koma pansi pamikhalidwe yoyenera, imayimira chogwirika, ngati chowonjezereka, sitepe yopita ku kusindikiza kokhazikika. Zatsopano sizili muzinthu zokhazokha, koma pakusintha zoyembekeza zogwira ntchito ndi malire ogwiritsira ntchito mankhwala achilengedwe.

Kumanga Zinthu Zofunika: Sikuti Nkhata Yokha

Kusamvetsetsana kwakukulu ndikuchitenga ngati khwangwala wamba. Si. Nkhata Nkhata Bay flange gasket ndi gulu, lomwe nthawi zambiri limaphatikizika ndi mphira wopangidwa ndi polima-nthawi zambiri mphira wopangidwa ngati NBR kapena SBR. Chithovuchi chimatanthawuza mawonekedwe a ma cell a cork, omwe amakulitsidwa ndikusakanikirana. The eco-claim imadalira pa cork oak kukhala gwero longowonjezwdwa; khungwa limaphukanso. Koma binder nthawi zambiri imakhala yochokera ku petrochemical. Ndiye, kodi ndi zachilengedwe? Poyerekeza ndi labala lopangidwa mwangwiro kapena pepala lopanikizidwa la asibesitosi, inde, mwamtheradi. Ndi njira yosakanizidwa, yochepetsera zinthu zopangira pomwe imathandizira kukhazikika kwachilengedwe kwa cork ndi kulimba mtima.

Ndimakumbukira kuyesa koyambirira kwa mzere wamadzi ofunda (otsika 90 ° C) pomwe tidalowetsa gasket yokhazikika. Ubwino wanthawi yomweyo unali torque ya bawuti yotsika yofunikira kuti asindikize bwino. Zachilengedwe za Cork zimagwirizana bwino ndi zolakwika zazing'ono. Koma tidawonanso kupsinjika kofulumira kukhazikitsidwa pamatenthedwe angapo oyamba. Idakhazikika, kenako idakhazikika, koma chiwopsezo choyambiriracho chidadetsa nkhawa gulu lokonza. Zinatiphunzitsa kuti kukhazikitsa ndikofunika kwambiri - simungangoyiyika ngati PTFE gasket ndikuyembekezera zomwezo.

Kachulukidwe ndi binder ratio ndi chilichonse. Katswiri wina anatitumizirapo zitsanzo zolembedwa kuti nkhwangwa ya thovu yotentha kwambiri. Zinapezeka kuti angowonjezera zomwe zili mu rabara kuti zikhazikike, zomwe, zachepetsa kuchuluka kwa nkhokwe zachilengedwe komanso phindu lake lobiriwira. Zinachita bwino, koma zimamveka ngati nyambo-ndi-kusintha kutsogolo kwachitetezo. Muyenera kukumba mu data sheet luso, osati dzina mankhwala.

Zenera Logwira Ntchito

Kodi zimawala kuti? Ma flanges otsika mpaka apakatikati amadzimadzi monga madzi, mafuta, ndi mankhwala ena pa kutentha kwapakati pa -40°C mpaka 120°C. Takhala tikuyenda nawo bwino pamalumikizidwe a pampu mu machitidwe a HVAC komanso mizere yosafunikira pazakudya ndi zakumwa. The luso lothandizira zachilengedwe apa pali zochepa zakusintha kusindikiza komanso zambiri zopezera njira yotheka, yoyipa pang'ono pazambiri zamafakitale okhazikika pomwe kuchita monyanyira sikofunikira.

Pali kulephera komwe kumamatira ndi ine. Wogula wina adaumirira kuti agwiritse ntchito chingwe cha condensate chapakatikati. Matenthedwe a kutentha anali mkati mwa kuchuluka kwake komwe kunanenedwa, koma kupalasa njinga mwachangu, konyowa kunali kwankhanza. Mpweyawo unawonongeka mkati mwa miyezi-osati mwangozi, koma zokwanira kupangitsa kulira kosalekeza. Phunziro linali lakuti kutentha kwakukulu komwe kumasindikizidwa nthawi zambiri kumakhala kutentha kosalekeza, kowuma. Ntchito zamadzimadzi padziko lonse lapansi komanso kupalasa njinga zotentha ndi zilombo zosiyanasiyana. Tsopano, timadumpha nthawi zonse kuyanjana kwamadzimadzi ndi ma frequency ozungulira ndi mtundu wa binder.

Kugwira ndi kusungirako kumasiyananso. Simungazisiye izi m'nkhokwe yonyowa, yamafuta. Amatenga chinyezi ndi mafuta kuchokera mumlengalenga, amatupa asanafike ku flange. Ndawona mapaketi akuperekedwa pomwe ma gaskets adawoneka bwino, kuwapangitsa kukhala opanda ntchito. Ndi mfundo yodziwikiratu, koma yomwe ikuwonetsa chidwi cha gawo lachilengedwe poyerekeza ndi zopanga za inert.

Supply Chain ndi Zowona Zopanga

Kupeza mtundu wokhazikika ndiye vuto lenileni. Kupanga sikuli kofanana ndi zitsulo kapena gaskets zoyera. Kukula kwa granule, kugawa, ndi binder homogeneity zimasiyana. Tagwira ntchito ndi opanga m'magulu apadera ogulitsa mafakitale, monga omwe ali pafupi ndi Handan ku China, omwe ndi malo opangira zomangira komanso zinthu zina. Kampani ngati Malingaliro a kampani Handan Zitai Fastener Manufacturing Co., Ltd., zochokera kudera limenelo (mukhoza kuzipeza pa https://www.zitaifasteners.com), ngakhale imadziwika ndi zomangira, imagwira ntchito m'chilengedwe momwe kupanga gasket nthawi zambiri kumakhala bizinesi yofananira. Malo omwe ali ku Yongnian District, gawo lalikulu kwambiri lopangira magawo ku China, ndi maulalo ake, amatanthauza kuti adalumikizidwa ndi netiweki yomwe ili ndi zida zopangira komanso ukadaulo wamakina pazinthu zosindikiza. Izi sizitanthauza kuti amapanga ma gaskets a thovu, koma zikuwonetsa momwe zinthu zatsopanozi zimayambira m'malo owundana, apadera opanga komwe kuyesa kwazinthu kumakhala kosalekeza.

Mukamayang'ana wogulitsa omwe angakhale nawo, muyenera kuyang'ana komwe akuchokera. Chipika cha Portugal? Nthawi zambiri apamwamba, mosasinthasintha khalidwe. Zigawo zina zimatha kukhala zosinthika. Otsatsa abwino adzakhala ndi ziphaso za kukhazikika kwawo kwa cork (FSC kapena zofananira), zomwe zimawonjezera kukhulupirika kwa eco-claim. Ochepa kwambiri amangolankhula za nkhaniyo mosamveka. Njira yomangiriza ndiyofunikira - iyenera kuvala granule iliyonse mofanana popanda kudzaza maselo achilengedwe. Ndilo gawo la ntchito.

Calculus Eco-Friendly Calculus: Kupitilira Gasket Lokha

Zowona zenizeni za chilengedwe ndikuwunika kwa moyo wonse. A gasket ya thovu Zitha kukhala zotsika kwambiri kuposa zomwe zimapangidwa, koma bwanji za moyo wake wautumiki ndi kutayidwa? Ngati zikulephera kawiri kawiri kawiri, mwapanga zowonongeka zambiri komanso nthawi yochepa. Muzochitikira zathu, zikagwiritsidwa ntchito moyenera mkati mwa zenera lake, moyo umakhala wofanana. Nkhani yakumapeto kwa moyo ndi yabwino; ndizosavuta kuziwotcha ndikubwezeretsa mphamvu kuposa mitundu ina yovuta ya elastomer, ngakhale chomangiracho chimasokoneza kuwonongeka kwathunthu kwachilengedwe.

Zatsopanozi zikuyendetsanso mpikisano. Tsopano tikuwona zomangira zochokera ku mphira wachilengedwe kapena ma polima opangidwa ndi bio akulowa mumsanganizo, ndikukankhira zomwe zili mu bio kuchokera mwina 60% kupita mmwamba. Ndi kusintha kwapang'onopang'ono. Mphamvu yoyendetsa si nthawi zonse yolamulira; nthawi zina ndi ntchito zamakampani za ESG kuchokera kwa ogwiritsa ntchito ku Europe kapena North America, kusefa zomwe zimaperekedwa kwa ogulitsa gasket ku Hebei.

Kuchokera pamalingaliro amtengo wapatali, nthawi zambiri zimakhala zotsika mtengo pamasamba oyambira koma zotsika mtengo kuposa PTFE kapena ma graphite composites. Kwa oyang'anira mbewu zambiri, mawonekedwe obiriwira ndi bonasi yomwe imathandiza kulungamitsa kugula koyenera, kupangitsa kuti kulera kukhale kosavuta.

Kutsiliza: Gawo Labwino, Osati Kusintha

Ndiye, kodi ndi zatsopano? Inde. Kodi ndi zachilengedwe? Mwachidule. Ndizinthu zowoneka bwino, zosakanizidwa zomwe zimathetsa mavuto enieni-kufanana, kuchepa kwa bawuti, zosinthikanso-popanda kunena kuti ndizabwino. Sichidzalowa m'malo mwa bala lozungulira kapena grafoil pa ntchito yovuta. Koma kwa zikwizikwi za ma flanges osindikiza madzi kapena mafuta, ndi chisankho cholimba, chodalirika. Chofunikira ndikuwongolera zoyembekeza: kumvetsetsa malire ake, gwero mosamala, ndikuyika ndi malingaliro ake enieni. Ndi chida chomwe chili m'bokosi, chomwe chimawonetsa kusintha pang'onopang'ono koma kowoneka bwino momwe ngakhale zida zamakampani zomwe zimaganiziridwanso. Izi, mwazokha, mwina ndiye chinthu chofunikira kwambiri chotengera.
