Iyo nzvimbo inofamba-famba pane screw yakangokosha seyechinyorwa checrewr pachayo. Screw tambo dzakagadzirwa kuburikidza nekucheka kana kugadzira machining maitiro, uye marara emusoro anopa yakakosha dhiji yekudzivirira kweiyo screw shank uye tambo.
Kuti uite izvozvo, zviyero zvinobatsirwa zvikuru kubva kune dzakasiyana siyana dzeinjini dzekupfeka dzekupfeka dzinogadziriswa kusvika kune imwe neimwe screw application kuitira kuti ubhadhare Corrosom uye kudzivirirwa.
Muchivande, zvemagetsi zvekumusoro zvinoshandiswa kumisikidza kuti uwedzere kupokana nekuchengetedza screw kubva pakutadza kwekutadza nekuda kwekutadza kana kupaza.
Saka, ndedzipi nzira dzinozivikanwa kwazvo dzekurwisa? Izvi zvinotevera ndizvo zvakajairika screw pamusoro nzira dzekurapa nzira:
1. Zinc Plating
Iyo inowanzoitika nzvimbo yekurapa nzira yeScrew is Electro Kurairira. Izvo hazvisi zvisingadhuri chete, asi zvakare zvine chitarisiko chakanaka. Electroplating inowanikwa mune dema uye mauto girini. Nekudaro, kumwe kukanganisa kweElectro Kuregedza ndeyekuti yayo yekurwisa-corrostion is general, uye ine yakaderera anti-corrostion performance ye chero pendi (coating) layer. Muzhinji, iyo screws mushure mekunge Electro arisheni inogona kupfuudza musango muedzo mukati memakumi manomwe nemasere ekushandiswa.
2. Chromium plating
Iyo Chromic inofamba-famba pane screw Forners yakagadzikana munharaunda, haichinjike nyore nyore ruvara kana kurasikirwa nekudyara, ine hutsinye, uye inopesana nekupfeka. Kunyangwe hazvo Chromic coating inowanzoshandiswa sekushongedza kwekushambadzira pane fasteners, hazviwanzo kushandiswa mune maindasitiri anodikanwa kupokana kwakanyanya. Nekuti yakanaka chrome yakarongedzwa fasteners inodhura senge simbi yesimbi, ivo vanofanirwa chete kushandiswa kana simba resimbi isina kukwana. Kuti avandudze chromium pleting kupesana kupokana, mhangura uye nickel inofanira kunge yakavezwa pamberi pechromium plating. Kunyangwe hazvo Chromic kuunganidza kunogona kutsungirira tembiricha yepamusoro ye1200 degrees Fahrenhees (650 degrees celsius), inotambura neyakafanana hydrogen dambudziko dambudziko sekuremerwa.
3. Sirivheri uye nickel plating pamusoro
Sirivheri inovhara screw fastenersinoshanda seyakasimba yakasimba yekuzvimhanya pamwe nesitiro yekudzivirira kuora. Nekuda kwekubhadhara, zviyero hazviwanzo kushandiswa, uye dzimwe nguva madhiri madiki zvakare zvakare sirivha. Kunyangwe iyo tarnish mhepo mumhepo, sirivheri ichiri kushanda kuma 1600 degrees Fahrenheit. Kuti ushande mukudziya kwakanyanya uye kudzivirira screw oxidation, vanhu vanoshandisa yavo yakanyanya kupisa kupesana uye kuumbwa kwehunhu. Fasteners idzo dzinowanzoitika Nickel-rakarongedzwa kunzvimbo dzisiri dzakakwirira dzekuita uye corrosion kuramba. Semuenzaniso, mota yemotokari inouya terminal.
4.Screw pamusoro kurapwaDachromet
Kurapwa kwepasi kweDachromet yeScrew FornersHaina iine hydrogen embrittlement, uye torque preloads nguva dzose inoita zvakanaka kwazvo. Nekudaro, zvinosvibisa zvakadzama. Pasina kufunga nezve nyaya ne chromium uye dziviriro yezvakatipoteredza, zvakanyatsokwaniriswa zvakanyanya kune simba rakanyanya kusimbisa zvine simba anti-corrosmion zvinodiwa.
5. Svutugadzike phazphating
Kunyangwe phospharating isingadhuri kupfuura organizing, inopa dziviriro shoma pamusoro peuto.Screw FornersInofanirwa kuve yakajeka mushure mekufadzwa nokufadzwa nekuti kuita kweoiri kune zvakawanda zvekuita nehurongwa hwekushomeka kwemashopu. Nyorera general Antirust mafuta mushure mekufona Nekuti yavo yeTorque uye pre-inosimbisa simba ine basa rakanaka rekusarongeka, ruzhinji rweshandare maindasitiri ekuzvidza anobatwa nemafashoni +. Izvo zvinowanzo shandiswa muchivakwa cheindasitiri nekuti zvinogona kugutsa izvo zvinofungidzirwa zvinodikanwa zvekunakidzwa panguva yeungano yezvikamu uye zvikamu. Kunyanya kubatanidza zvimwe zvinhu zvakakosha, zvimwe zviyero zvinoshandisa kufonera, izvo zvinogona zvakare kudzivirira nyaya yeiyo hydrogen embbrttlement. Nekuda kweizvozvo, mumunda weindasitiri, screwith giredhi rakakwirira kupfuura 10.9 dzinowanzove dzakadzikira.
