Kana mumwe munhu abvunza nezve 'simba rakakwirira dema nut durability,' fungidziro yekukurumidza kazhinji ndeyekupfekedza-kuti black oxide kana black phosphate kupera. Asi mukuita, iyo ingori iyo inooneka layer. Kukurukurirana chaiko kunotanga neyakagadzika zvinhu, maitiro ekupisa kupisa, uye kutaura chokwadi, iyo chaiyo nharaunda iyo inofanirwa kurarama. Ndakaona akawanda maspecs anongodaidza 'black Giredhi 8' tisingatarise kuti ndeyekuoma, kuungana kwemukati kana chimiro chekunze chakatarisana nemahombekombe emunyu wekupfapfaidza. Chikamu 'chitema' hachisi nhovo yemashiripiti; iyo inobatsira mukudzivisa kuora uye aesthetics, asi 'simba guru' uye 'kusimba' inyaya yakadzama yeinjiniya.

Kudhirodha 'Kusimba Kwakakwirira' - Haisi Chete Chiratidzo

Mumutsara wedu, 'simba repamusoro' rinowanzonongedza kumakirasi ezvivakwa se8, 10, kana 12. Kune nzungu, kuenzanisa kusimba kwebhaudhi kwakakosha kuti usabvisa shinda-yechinyakare yekutadza point. Tiri kutaura pamusoro pekudzimwa uye kudziya kwepakati kabhoni simbi, kana alloy simbi yemagiredhi epamusoro. Kugara pasi pemutoro kunotsamira pane izvi. Ndinoyeuka imwe purojekiti yemuchina unorema apo mutengi aisimbirira kushandisa nzungu dzeGrade 5 dzakasvibira dzakapera nemabhaudhi eGrade 8, achifunga kuti ruvara rwacho rwaienderana nerunako. Mumwedzi mishomanana, takava nemishumo yokusabatanidzwa. Nzungu dzakanga dzabereka. Iyo 'dema' yaive yakanaka; kusimba kwenyama ndiko kwaive kusapindirana. Uku ndiko kutadza kusimba kwakadzika midzi mune yakatarwa, kwete kukoira.

Iyo hubhu yekugadzira muYongnian, Hebei, ndiko kwaunoona ichi chikero chichiita. Mutengesi akafanana Handan Zitai Fastener Kugadzira Co, Ltd., inoshanda kubva kune iyo huru yekugadzira base, ine zvivakwa zvekudzora simbi uye kupisa kurapwa muhuwandu. Nzvimbo yavo pedyo nemigwagwa mikuru yekufambisa haisi nzvimbo yekutengesa chete; zvinoreva kuenderana kwekushandisa kwezvinhu zvakasvibirira uye kugadzirwa kweiyo inorema tonnage iyo yakakwirira-simba rekusimbisa kugadzirwa kunosanganisira.

Saka, iwe unoitonga sei? Certification uye mishumo yebvunzo. Mugadziri akavimbika anofanira kupa zvinhu certs uye humbowo hwemakanika zvivakwa. Kuoma, kusimba kwesimba, mutoro wakavimbiswa-nhamba idzi dzinotaura nyaya yekugara kwenguva refu nzungu isati yamboona chipanera. Kupera kwakasviba kunenge kwave kufunga mune yebvunzo lab, asi ndicho chinhu chekutanga icho munhu wekutenga zvinhu anoona.

The Black Finish - Basa Rinopfuura Ruvara

Ngatitaure nezve 'dema' pacharo. Kazhinji kacho chivharo chekushandura, kwete plating. Iyo haina kuwedzera ukobvu senge zinc plating, iyo yakakosha kuchengetedza chaiyo tambo kushivirira pane yakakwirira-simba nzungu. Basa rayo rekutanga kurwisa corrosion, asi inyoro. Inopa chipingamupinyi chakanaka kurwisa oxidation mumhepo yakajairwa uye inopa hwaro hwakanaka hwekubata mafuta kana wakisi. Isu tinowanzo kunyudza nzungu dzakasvibiswa mumafuta akareruka, ayo anowedzera kuchengetedzwa kwawo kwenguva pfupi kwecorrosion uye anopa iwo hunhu hushoma kupenya.

Nekudaro, ini ndakave nechikamu changu chekusanzwisisana nevatengi vachitarisira kuti kupera uku kuite sekupisa-dip galvanizing. Hazvizoiti. Munzvimbo yakakwirira-yakanyorova kana kemikari, black oxide chete inoratidza tsvuku tsvuku nekukasira. Kugara kwayo muzvirongwa zvinoodza zvishoma. Takadzidza izvi nenzira yakaoma tiri muchikwata chakatumirwa kune imwe imba inochengeterwa zvinhu pedyo nemhenderekedzo yegungwa. Nzungu dzacho dzaitaridzika zvakanaka pakusununguka asi dzairatidza kuva nemakwapa mukati memavhiki. Kugadzirisa kwakanga kusiri 'zviri nani' kupera kwakasviba; yakanga ichichinjira kune imwe chirevo chakasiyana zvachose chemhoteredzo iyoyo.

Kubatsira kweiyo dema kupera kwekugara kune imwe nzira isina kunanga. Iyo ine yakanakisa abrasion resistance kana ichienzaniswa nemamwe maplated coatings. Iyo yekupfekedza inosanganiswa mukati mepamusoro, saka haibvire nyore panguva yekuisa kana pasi pekudengenyeka. Izvi zvinobatsira kuchengetedza corrosion barrier yainopa. Zvekushandisa uko gungano rinogona kuona kubata kwakawanda kana kukweshwa kudiki, icho chinobatika bhenefiti.

Real-World Durability - Vibration, Temperature, uye Kuneta

Durability haisi yekungoita ngura chete. Kune nut yakasimba-yakasimba, kugona kwayo kugara pasi pemitoro ine simba ndiyo yakakosha. Apa ndipo panopinda dhizaini senge torque iripo (senge mune naironi isa locknuts) kana akaremara shinda mapatani anouya, anowanzo shandiswa mushure meiyo dema oxidizing process. Kudyidzana pakati peiyo yekuvhara chimiro uye kupera kwakasviba kunoda kutariswa. Dzimwe nguva, ukobvu hwekuvhara, kunyangwe hushoma, hunogona kukanganisa kukiya torque kuenderana. Idiki diki dhizaini yekudzora iyo inoparadzanisa batch yakanaka kubva kune yakakura.

Tembiricha ndeimwe muurayi akanyarara. Nzungu dzakadzimirwa uye dzakadzikama dzakakwirira dzine tembiricha yepamusoro. Kupfuura izvozvo, uye hasha dzinokweva, simba rinodonha, uye kusimba kunodonha. Ndinoyeuka kubvunza kwechikamu cheinjini uko tembiricha yekushanda yaive padyo nemuganhu wekirasi yezvinhu. Isu taifanira kusunda kumashure nekukurudzira giredhi rakasiyana, kunyangwe mutengi aitarisa mutengo wekutanga. Chiyero che‘black high-simba nut’ yakanga isiri mhinduro yakarurama. Iyo dema inopedzisa pachayo inogona zvakare kudzima pane yakakwira tembiricha, inova yekushongedza asi dzimwe nguva yakakosha kufunga.

Kuneta kukundikana ndiko kunonyengera zvakanyanya. Izvo zvinoitika pamazinga ekushushikana zviri pasi pesimba rekusimba. Hunhu hwekutenderedzwa kweshinda, kusavapo kwekukanganisika kwepamusoro kana madiki madiki kubva mukugadzira, uye kutsetseka kwekupedzisa zvese zvinokanganisa hupenyu hwekuneta. Iyo yepamusoro-yemhando yeblack oxide process, iyo inonyanya kudzorwa ngura, haifanire kuunza hydrogen embrittlement-njodzi ine mamwe maitiro e electroplating. Izvi zvinogadzira yakanyatsogadziriswa dema oxide nati sarudzo yakachengeteka kune yakakwirira-simba, yakakwirira-kuneta maapplication kubva pakuenda.

Kutsanangura Hupenyu Hwechokwadi Hwebasa

Saka, unotsanangura sei kusimba? Unotanga nemhoteredzo. Indoor, controlled atmosphere? A standard black oxide paKirasi 10 nzungu ingangove yakawanda kudarika kukwana. Kunze, maindasitiri, kana hunyoro hwakanyanya? Ungangoda iyo oxide yakasviba sehwaro asi tsanangura imwe topcoat yewakisi kana inorema mafuta dip. Kune nharaunda dzakaomarara, iyo dema kupera inogona kungova yekushongedza pasi peiyo yakasimba coating system, kunyangwe izvo zvisinganyanyi kujaira kune nzungu nekuda kweshinda kushivirira nyaya.

Izvo zvakare nezvekudyidzana nemugadziri wekugadzira. Iwe unoda mutengesi anonzwisisa aya nuances, kwete chete anotengesa chigadzirwa chegeneric. Paunenge uchiongorora kugona kwekambani, senge zvaunogona kuona pane saiti senge https://www.zitafornasteers.com, Ndinotarisa humbowo hwekutonga kwemaitiro-mabatiro avanoita mijenya yekurapa kupisa, maitiro avo ekutarisa pakubatisa adhesion uye kushomeka kwekudzivirira (salt spray test hours), uye kuda kwavo kupa ruzivo ruzivo. Mugadziri akanyudzwa muhukuru hwekugadzira hwaro seYongnian kazhinji ane mukana weakasarudzika, tiered ekupa cheni dzekupedzisa uye giredhi zvinodiwa.

Chekupedzisira, usamborerutsa kuisa. Durability yakagadzirwa mukati asi inogona kuiswa kunze. Kuwedzeredza-kukwenya kwepamusoro-simba dema nati inogona kuitambanudza, ichikanganisa simba rayo rekusunga uye corrosion barriers. Kushandisa mafuta asiri iwo pashinda kunogona kupindirana neblack oxide coating. Mugadziri anofanira kuziva zvavari kubata. Isu takatotanga kusanganisira ekutanga kubata manotsi nekutakura kwakawanda nekuti inochengetedza misoro kuzasi.

The Pazasi Line - A Balanced System

Pakupedzisira, kusimba kwepamusoro-simba dema nut inzvimbo yehurongwa. Ndiyo muchato weiyo chaiyo core material uye mechanical properties (iyo 'yakakwirira simba'), yakakodzera uye inoshandiswa zvakanaka pamusoro pekurapa (iyo 'dema'), uye kusarudzwa kwakakodzera kwenzvimbo yekushanda. Iwe haugone kurambana mumwe kubva kune mumwe. Mhedzisiro yakasviba yakakwana pane pasi-simba nut inokundikana. Nati yeGrade 12 yakabikwa nekupisa iine hurombo-husina kunaka, ine zvigamba nhema yakarembera ichatanga kuita ngura, uye gomba iroro rekuora rinova rinokonzera kushushikana, zvichiita kuti kuneta kutsemuka.

Zano rangu ndere kuyedza mune chaiyo application kana zvichibvira. Odha bhechi remuenzaniso, riise kuburikidza neyakateedzerwa sevhisi kutenderera, kana kungoita inodzorwa yakamhanyisa corrosion bvunzo. Wona kuti kupera kwakamira sei, tarisa kuti kune galling panguva yekuisa, uye simbisa hukama hwe torque-tension. Iyi bvunzo inoshanda inokuudza iwe kupfuura chero data sheet.

Pakupedzisira, inhengo inoita seyakapusa asi inobata masimba akaomarara. Kuwana kusimba kwayo ndeyekuremekedza iyo yakaoma, kutarisa kupfuura iyo ruvara rwepamusoro, uye kutarisa kune yese cheni yezvinhu, kugadzira, kutsanangurwa, uye kushandiswa. Ndiko kunovakwa kwechokwadi, kuita kwakavimbika.
