Giredhi 8.8 Nhema Oxide Hex Socket Musoro Cap Screws-Iyo Tekinoroji Yepamusoro yeCorrosion Dziviriro uye Musoro Dhizaini. 

2. Grade 8.8 Black Oxide Pedzisa: Corrosion Protection

2.1 Chii chinonzi Black Oxide?

Black oxide, inonziwo kusviba, ikemikari inoshandura coating inogadzirwa nekuita pamusoro pesimbi ine ferrous nealkaline oxidizing mhinduro pane yakakwirira tembiricha (kazhinji 140 kusvika 150 degrees Celsius). Kusiyana ne electroplated coatings senge zingi kana Dacromet, iyo inoisa yakaparadzana metallic layer pamusoro pe substrate, dema oxide inoshandura iyo yepamusoro-soro yesimbi pachayo kuita magnetite (Fe3O4), yakagadzikana dema iron oxide. Mhedzisiro yacho inzvimbo yakatetepa, ine matte-dema inova chikamu chakakosha cheiyo fastener pane yekuwedzera-pane layer.

2.2 Iyo Black Oxide Maitiro

Iyo yakajairwa dema oxide maitiro eGiredhi 8.8 fasteners inosanganisira anotevera matanho:

Degreasing uye alkaline kuchenesa kubvisa mafuta, kucheka zvinwiwa, uye zvinosvibisa zvezvitoro.

Acid pickling kubvisa chero chiyero chepamusoro kana ngura yakareruka.

Kunyudzwa mumvura inopisa ine alkaline-oxidizing (inoda kusvika 141 degrees Celsius), apo magnetite layer inoumba mumaminitsi gumi kusvika makumi maviri.

Kusuka uye kuvhara nemafuta ekudzivirira ngura kana wakisi, iyo inowedzera oxide layer ine hydrophobic barrier.

2.3 Corrosion Resistance Hunhu

Payo pachayo, iyo dema oxide layer yakatetepa (inenge 0.5 kusvika 1.5 micrometer) uye ine porous, zvinoreva kuti inopa chete zvine mwero kushora kuramba kana zvichienzaniswa ne zinc plating kana inopisa-dip galvanizing. Zvisineyi, kana yasanganiswa nemafuta ekuwedzera anodzivirira ngura kana wakisi, kupfekedzwa uku kunogonesa kusapindira kwemunyu kupfapfaidza kwemaawa angangoita makumi maviri nemana kusvika makumi mapfumbamwe nematanhatu, zvichienderana nemhando yekuvharisa. Iyi nhanho yedziviriro yakakwana kune yemukati, inodzorwa nemamiriro ekunze, kana zvinyoro zvinyoro nharaunda uko chisungo chisingaonekwe kune yakananga hunyoro kana munyu kupfapfaidza kwenguva yakareba.

2.4 Zvakanakira uye Zvinogumira

1.Zero dimensional shanduko: Nekuti iyo oxide layer iri pasi pe2 micrometer gobvu, dema oxide haishandure kushivirira kweshinda. Giredhi 8.8 fasteners inochengetedza yavo yepakutanga Kirasi 6g yakwana, ichiita iyo coating yakanakira magungano chaiwo uko kupindira kweshinda kunofanirwa kudzivirirwa.

2.Inodhura-inoshanda: Black oxide ndeimwe yeakanyanya hupfumi pamusoro pekurapa aripo, yakachipa zvakanyanya pane zinc-nickel plating, Dacromet, kana simbi isina tsvina.

3.No hydrogen embrittlement: Kusiyana neelectroplating, iyo yakasviba oxide process haiburitse hydrogen gasi, ichibvisa njodzi yehydrogen embrittlement. Izvi zvakakosha kune Giredhi 8.8 fasteners inoshanda pane yakanyanya kushushikana.

4.Aesthetic kukwezva: Iyo yunifomu matte-dema kupedzisa kunopa kuchena, kutaridzika kwehunyanzvi kunosanganiswa nemagungano eruvara rwerima uye kuderedza kupenya kwechiedza.

5.Limitation - Yakaganhurirwa yekunze corrosion resistance: Black oxide haikodzere kunze, mugungwa, kana nharaunda dzine ngura zvakanyanya. Nezvekushandisa kwakadaro, Dacromet, zinc-nickel plating, kana simbi isina tsvina inofanira kutariswa.

3. Cylindrical Head ine Hex Socket Drive

3.1 Dhizaini Yekutarisa

Musoro wecylindrical (unowanzo kunzi socket head cap screw head kana DIN 912 / ISO 4762 musoro) inoratidzira yakadzika-yepamusoro cylindrical chimiro ine yakadzoreredzwa hexagonal socket pakati. Iyo dhayamita yemusoro inowanzoita 1.5 nguva yezita reshinda dhayamita, uye kureba kwemusoro kunosvika 0.6 kusvika 1.0 nguva yedhayamita yeshank, zvichienderana nehukuru. Iyi geometry inopa yakakura kubereka nzvimbo pasi pemusoro uchichengeta iyo yakazara mbiri compact uye yakaderera-mbiri.

3.2 Zvakanakira zveCylindrical Head Design

High clamping simba: Musoro wecylindrical unopa yakakura kubereka nzvimbo pane countersunk kana bhatani musoro dhizaini, kugovera clamping mutoro pamusoro penzvimbo yakakura uye kuderedza njodzi yekudzika pasi kana kukuvadzwa kune workpiece.

Compact footprint: Nekuti musoro unogara pamusoro pepamusoro pane kunyura, musoro wecylindrical unongoda nyore kuburikidza neburi kana gomba rakatepwa. Hapana countersinking operation inodiwa, kurerutsa kugadzira.

Flush kana kusimudzwa kuisirwa: Musoro unogona kuisirwa flush nepamusoro (kana application ichibvumidza musoro wakasimudzwa) kana kudzoreredzwa mucounterbore kuti ipedze kupera, ichipa dhizaini inoshanduka.

Chitarisiko chakachena: Musoro wakatsetseka wecylindrical unopa kutaridzika, yunifomu inofarirwa mumuchina, zvishandiso, uye zvemagetsi zvevatengi.

3.3 Hex Socket Drive Benefits

Iyo hexagonal socket (Allen) drive ndiyo inotsanangura chimiro chesocket head cap screw. An Allen hex kiyi (wrench) inobata iyo matanhatu-poinzi recess, ichiendesa torque kutyaira screw. Iyi drive system inopa akati wandei akasiyana mabhenefiti pamusoro pekunze hex, Phillips, kana slotted madhiraivha:

Yakakwira torque kutapurirana: Iyo yemukati hex socket inogona kumira zvakanyanya yakakwira torque kupfuura Phillips kana slotted madhiraivha, ichigonesa kusimba kwakavimbika kune yakakwira preload values inodiwa kune Giredhi 8.8 fasteners (kusvika 80% yehumbowo mutoro mumajoini akakosha).

Cam-out kuramba: Kusiyana nePhillips madhiraivha akagadzirirwa kubuda (kubvisa) pasi peyakanyanya torque, iyo hex socket inochengetedza kubatanidzwa kwakazara, ichideredza njodzi yekutsvedza kwechishandiso uye kukuvara kwemusoro.

Yakaderera-mbiri yekuwana: Iyo hex kiyi inosvika kubva kumusoro (axial kutungamira), ichibvumira kuisirwa munzvimbo dzakavharirwa uko wrench isingasvike kubva padivi. Izvi zvinonyanya kukosha mumajini ane dense maassemblies.

Yakaderedzwa yekubvisa njodzi: Iyo hombe yekuonana nzvimbo pakati peiyo hex kiyi uye socket madziro inogovera kushushikana zvakaenzana, ichideredza mukana we socket madziro deformation kana kubviswa, kunyangwe mushure mekudzokororwa kuisirwa uye kubvisa kutenderera.

4. Typical Applications

Giredhi 8.8 dema oxide hex socket head cap screws anoshandiswa pahupamhi hwakawanda hwemaindasitiri panodiwa simba repakati-pamusoro, indoor corrosion dziviriro, uye compact musangano kupinda kunodiwa:

Michina nekugadzira michina: Injini yekumisikidza, giya bhokisi dzimba, magungano epombi, uye zvimiro zvemafuremu ekubatanidza.

Motokari (yemukati uye isina-yakafumurwa zvikamu): Dashboard magungano, zvigaro zvezvigaro, mabhuraketi emukati emukati, uye zvinhu zvepasi-hood zvakadzivirirwa kubva kune yakananga mamiriro ekunze.

Zvishandiso uye zvigadziriso: Mold mabhesi, jig uye fixture magungano, uye maseti ekufa uko kurovedzera chaiko uye kudzokororwa disassembly kwakajairika.

Electronics uye zvakavharirwa: Zvishandiso zvakaiswa Rack, mabhokisi emagetsi ejunction, uye mapaneru ekudzora uko kunonatswa dema dema uye yakaderera-mbiri inosarudzwa.

Furnicha uye yekuvaka Hardware: Modular fenicha majoini, maratidziro anomira, uye yemukati yekuvaka fittings.

5. Mhedziso

Giredhi 8.8 dema oxide hex socket musoro cap screws inomiririra yakanyatso dzikamisa fastener mhinduro inogadzirisa zviviri zvakakosha zveinjiniya zvinodiwa panguva imwe chete. Iyo dema oxide kupera inopa yakatetepa, ine dimensionally kugadzikana, hydrogen-embrittlement-isina corrosion barriers iyo ine hupfumi uye inowirirana inotaridzika. Nepo kushora kwayo kukadzikira kana ichienzaniswa neayo premium coatings seDacromet kana zinc-nickel, inodarika kukwana kwemukati uye zvinyoro nharaunda nharaunda. Iyo cylindrical musoro ine hex socket drive, zvakadaro, inopa yepamusoro torque kutapurirana, kompakiti yekumisikidza kugona, uye yakachena aesthetic inoita kuti ive sarudzo inosarudzika yemakanika magungano uko nzvimbo, kuvimbika, uye chitarisiko zvese zvine basa. Pamwe chete, zvinhu zviviri izvi zvinoita kuti Giredhi 8.8 dema oxide socket head cap screw ishande, inodhura-inoshanda, uye inovimbika yekusungirira kune yakafara dhizaini yekushandisa mumaindasitiri.
