Electro-galvanized cross countersunk kubowola ulusi durability? 

Mukuwona funsoli likutuluka m'mafotokozedwe kapena kuchokera kwa kasitomala, ndipo zomwe zimachitika m'matumbo nthawi zambiri zimakhala, Ndi chomangira chodzibowolera chokha, chingakhale chovuta bwanji? Ndilo msampha woyamba. Kunena zoona, durability wa kubowola ulusi pa electro-galvanized cross countersunk head screw si chinthu chimodzi; ndi nkhondo yowonongeka, yothandiza pakati pa zokutira, zitsulo zoyambira, chithandizo cha kutentha, ndi zomwe mukuyendetsa. Ndawona zolephera zambiri pomwe ulusi umang'ambika mdzenje kapena mfundoyo imaduka, osati chifukwa chakuti zomwe zidali zolakwika pamapepala, koma chifukwa kulumikizana kunali kolakwika m'munda.

Kusamvetsetsana Kwambiri: Kuphimba vs. Magwiridwe

Anthu ambiri amakhazikika pama electro-galvanized layer ngati ngwazi yokhayo yolimbana ndi dzimbiri. Ndipo zedi, pa shelufu yoyambira m'nyumba yosungiramo zinthu zowuma, ndizabwino. Koma tikamalankhula kukhazikika ulusi wobowola wokha-kuthekera kwake kudula bwino, kugwira torque, komanso kusatha msanga - plating ya zinki imakhala ngati mbali. Ikhozanso kukhala woipa. Ma electro-deposit okhuthala, osayendetsedwa bwino amatha kuzunguliza mbali zakuthwa za ulusi. Ndidayezera zitsanzo pomwe plating idawonjezera 15-micron wosanjikiza, ndikuchepetsa kutsogolo kwa chitoliro. Chophimbacho chikhoza kuyesa kuyesa kupopera mchere koma kulephera kubowola chitsulo cha 1.2mm pakuyesera kakhumi.

Nyenyezi yeniyeni ndi chitsulo chapansi panthaka ndi chithandizo chake cha kutentha. Chomangira cholimba, chotsika cha carbon steel screw chimakhala ndi chobowola cholimba, chosasunthika chomwe chimatha kudumpha pansi pa katundu wina. Aloyi yolimba, yapakati-carbon idzakhala yolimba koma imatha kuvala mwachangu. Kuti ulusi ukhale wolimba, mfundoyo iyenera kukhala yolimba kuposa zomwe ikudula, koma shank kumbuyo kwake imafuna mphamvu yokwanira yogwedeza kuti isamete. Kupeza gradient molondola ndi luso. Ndikukumbukira gulu lochokera kwa ogulitsa - tinene wina wodziwika bwino wochokera ku Chigawo cha Yongnian, malo opangira zinthu ku Hebei - komwe kupsya mtima kunalipo. Zomangirazo zimabowola bwino koma kenako mituyo imatuluka ndikumangidwa komaliza. The ulusi chinali cholimba, chomangira sichinali.

Izi zimatsogolera ku mayeso othandiza omwe tidayamba kuchita m'nyumba: kuyesa motsatizana. Sitimangoyendetsa screw imodzi mu gulu loyesera. Timatenga chitsanzo ndikuchiyendetsa kumalo atsopano pa pepala lachitsulo, ndikubwezeretsanso, ndikuchitanso. Kakhumi. Mumayang'ana ulusi kuti muwone ngati wapindika, kunyamula zitsulo, komanso kuvala m'mbali. Zomangira zama electro-galvanized nthawi zambiri zimawonetsa zinc kupaka pambuyo pa mkombero wachitatu kapena wachinayi, zomwe zimakulitsa torque yagalimoto ndipo zimatha kupangitsa kulephera msanga. Chophimbacho ndi chopereka nsembe, chomwe ndi chabwino kwa dzimbiri koma choyipa kuti mukhale ndi jiometri yakuthwa.

Udindo Wobisika wa Countersunk Head

Ndikosavuta kunyalanyaza mutu. Mtanda (Phillips kapena Pozi) ndi mbali ya countersunk sizongokhala chabe. Za kukhazikika, mutu uyenera kukhala mokwanira komanso mwaukhondo kusamutsa torque yoyika bwino mu ulusi wobowola. Ngati chopumiracho chili chozama kapena dalaivala akutuluka, mumapereka zinthu zododometsa ndikuchotsa popuma ulusi usanamalize. Izi zimawononga dzenje ndi chomangira. Tidakhala ndi pulojekiti yogwiritsa ntchito zomangira za CSK zomangika ndi electro-galvanized polumikiza zitsulo zonyezimira. Ogwira ntchito m'mundamo adawonetsa kuchuluka kwapang'onopang'ono kwapang'onopang'ono. Nkhani sinali pobowola wononga; zinali kuti electroplating anali atamanga mkati mwa recess, kusintha chinkhoswe mbiri yake. Kutsika kwachangu pochotsa plating kukanathetsa, koma sitolo idalumpha sitepeyo kuti ipulumutse mtengo.

Kukhala pamutu kumakhudzanso ulusi wautali wautali. Mpando wopanda ungwiro umapanga pivot point, kulola kugwedezeka kugwira ntchito pa ulusi womwe walumikizidwa. Ndawona ming'alu ya kutopa ikuyambira osati pa ulusi woyamba, koma pakati pa shank, chifukwa cha mphindi yopindika iyi. Chifukwa chake, funso lokhazikika limakulitsa cholumikizira chonse. Ulusi wobowola bwino umatsitsidwa ndi mutu wosapangidwa bwino nthawi zonse.

Ponena za ogulitsa, mumaphunzira kuyamikira omwe amamvetsetsa kuyanjana uku. Pali wopanga, Handan Zitai Fastener Manufacturing Co., Ltd., akugwira ntchito kuchokera ku maziko akulu a Yongnian. Tsamba lawo (https://www.zitaifasteners.com) mwatsatanetsatane zomwe amayang'ana pakupanga zinthu. Kuchokera ku zomwe ndawona, mtengo wawo sikungopanga gawo lokhazikika, koma poyang'anira zochitika zobisika izi-monga kuonetsetsa kuti makulidwe a plating amayendetsedwa pamalo ovuta. Ndi chisamaliro chamtunduwu chomwe chimapangitsa kuti chinthucho chichoke paukadaulo kupita ku cholimba m'munda.

Zosintha Zam'munda: Zomwe Mapepala Sanena

Palibe kukambirana kokwanira popanda chisokonezo chenicheni. Mutha kukhala ndi zomangira zodzibowolera bwino zama elekitirodi, kenako zimakumana ndi chitsulo chopakidwa utoto. Utotowo umakweza chitoliro, umawonjezera kutentha, ndipo ulusi wofewa wa zinki umagwira ulusi. Kukhazikika kumatsika. Kapena kusintha kwa makulidwe a gawo lapansi. Malo obowola amakometsedwa, mwachitsanzo, chitsulo cha 2mm. Ithamangitseni mu 1.5mm, ndipo siimaluma mokwanira kuti itulutse chip choyera; imayendetsa mu 3mm, ndipo imagwira ntchito-imapangitsa chitsulo patsogolo pa ulusi, kuchititsa kuti zisawonongeke. Ulusi wokhazikika umakhala wokhazikika mkati mwa zenera lazantchito.

Ndiye pali kusintha kwa installer. Woyendetsa galimotoyo ndi mfumu tsopano, koma torque yake yothamanga ndi yankhanza m'mphepete mwa ulusi wamagalasi a electro-galvanized. Dalaivala wobowola wa RPM nthawi zonse ndi wofatsa ndipo atha kupangitsa kuti mabowo akhale abwinoko komanso moyo wautali wa zida za screw pachokha. Tidayesa kufananiza: batch yofananira, zida zosiyanasiyana. Zitsanzo zoyendetsa galimoto zidawonetsa kupindika kowonekera pa ulusi wotsogolera m'mphepete pambuyo pa ma cycle 5. Zitsanzo zoyendetsa kubowola zinali zoyera pambuyo pa 8. Kupaka kunali kofanana. The kubowola ulusi kukhazikika kumayendetsedwa ndi njira yoyika.

Kusanthula kulephera nthawi zambiri kumabwereranso kuzinthu zofewa izi. Nthawi ina kontrakitala wina anadandaula za kuvula ulusi. Tapezanso zitsanzo zomwe zidalephera. Chophimba chopangidwa ndi ma electro-galvanized chinali kuvalidwa mu mawonekedwe a helical, ndipo zitsulo zoyambira zimawonetsa zizindikiro za kuvala zomatira. Wolakwa? Ankagwiritsa ntchito zomangirazo kumamatira mabulaketi kumitengo yazitsulo zosapentidwa, zoviikidwa ndi malata. Kuyanjana kwa zinc-on-zinc, kuphatikizapo kuuma kwakukulu kwa zokutira za HDG, zinkakhala ngati phala lopweteka. Yankho lake silinali zomangira zolimba kwambiri zama electro-galvanized, koma kusinthana ndi galati kapena phula lopaka phosphate pamphambanoyo.

Kuphatikizika kwa Zinthu Zakuthupi ndi Kukwera kwa Corrosion

Electro-galvanized ndi nsalu yopyapyala, yoperekera nsembe. Udindo wake pakulimba kwa ulusi makamaka ndi kupewa dzimbiri lofiyira lomwe lingayambitse kugwidwa kwa ulusi kapena kutayika kwa zingwe pakapita nthawi. Koma m'malo onyowa kapena owononga, zinc imachepa. Ndathyola zomangira panja patatha miyezi 18. Ulusi wobowola, wokwiriridwa mu gawo lachitsulo, nthawi zambiri umakhala wowoneka bwino kuposa shank yowonekera. Chifukwa chiyani? Zinali zotetezedwa ndi mgwirizano wapamtima wachitsulo ndi zitsulo. Kuwonongeka kwa dzimbiri kunali koyipa kwambiri pamalo olowera ulusi, pomwe chinyezi chimatha kutha. Zowonongekazi, zinc carbonate, ndizochuluka. Ikhoza kutseka mwakuthupi ulusi kapena, mosiyana, kusungunula ndikusiya kusiyana, kumasula mgwirizanowo.

Choncho, kulimba kwa nthawi yaitali sikungovala makina okha; ndi kuwonongeka kwa electrochemical. Ngati ntchitoyo ndi yoyikapo mpaka kalekale m'malo owononga pang'ono (monga nyumba yosungiramo zinthu zamkati yomwe imakhala ndi condensation mwa apo ndi apo), malata amagetsi okhazikika ndi okwanira. Koma ngati pali mwayi uliwonse wobwereza zowuma zowuma, kukhazikika kwa mphamvu yogwira ulusiyo sikumasokonezedwa osati chifukwa chakutha, koma chifukwa cha dzimbiri la olowa. Mumayamba kuganiza za sealants kapena washers, kusuntha kupyola chomangira chokha.

Izi zimandibwezeranso ku funso loyamba. Kufunsa za kukhazikika kwa an electro-galvanized cross countersunk kubowola ulusi zili ngati kufunsa za mmene injini yagalimoto imayendera—zimadalira mmene ikuyendetsedwera, matayala, kayendetsedwe kake, ndiponso mmene mafuta amayendera. Ulusi ndi gawo la dongosolo. Chophimba chopangidwa bwino kuchokera ku malo olamulidwa ngati maziko akuluakulu opanga ndi chiyambi chabwino. Koma kulimba kwake komwe kumazindikirika ndiko kukambirana pakati pa kapangidwe kake, zokutira zake, zida zomwe zimagwirizana nazo, ndi mphamvu zomwe zimagwiritsidwa ntchito. Palibe yankho limodzi, zokumana nazo zokha zomwe zimakuuzani komwe zingalephereke, kotero mutha kukonzekera moyenera.

Kumaliza Popanda Mapeto

Kotero, chotsatira ndi chiyani? Osatengera zomwezo ngati chitsimikizo. Ngati kukhazikika ntchito yobowola ndiyofunikira, tchulani kuyezetsa kwa magwiridwe antchito komwe kumatengera momwe mumagwiritsira ntchito: mtundu wazinthu, makulidwe, chida choyendetsa, ndi kuwerengera kuzungulira. Yang'anani ndondomeko ya ogulitsa pa chithandizo cha kutentha ndi plating. Kampani ngati Handan Zitai Fastener, yomwe ili pamalo akuluwo ndi zabwino zake, nthawi zambiri imakhala ndi sikelo ndikuyang'ana kwambiri pakuwongolera izi, koma muyenera kutsimikizira. Funsani deta yawo yamkati ya QC pa mbiri ya kuuma kwa ulusi ndi kugawa makulidwe a plating.

Pamapeto pake, ulusi wokhazikika kwambiri ndi womwe umagwirizana bwino ndi ntchito yake. Nthawi zina, izi zikutanthauza kusiya ma electro-galvanized kuti amalize mosiyana, kapena kusankha geometry yosiyana. Funso lomwe lili pamutuwu ndiye poyambira bwino, koma yankho silimangokhala pamndandanda. Zili m'sitolo, pa benchi yoyesera, ndi m'munda, wokutidwa ndi fumbi la zinki ndi zitsulo zachitsulo, poganizira chifukwa chake phula lachisanu linayendetsa molimba kuposa loyamba. Ndipamene mumapeza deta yeniyeni.
