1. Selelekela

Li-screws tse entsoeng ka hex socket head cap tse lumellanang le maemo a DIN 912 li emela tharollo e tiileng e sebetsang hantle e kopanyang bokhabane ba li-screws tsa hlooho ea socket e entsoeng ka mokhoa o nepahetseng le ho hanyetsa ho hoholo ha kutu ea Dacromet. Li-fasteners tsena li sebelisoa haholo lits'ebetsong tsa likoloi, tsa kaho, tsa leoatleng, tsa moea, le lits'ebetsong tsa mochini oa indasteri moo botšepehi ba sebopeho le ts'ireletso ea nako e telele e leng bohlokoa.

Sengoliloeng sena se fana ka tlhaiso-leseling e qaqileng ea tekheniki ho tsoa mekhoeng e 'meli: ts'ebetso ea ho roala ea Dacromet, e fanang ka li-fasteners tsena thepa ea tsona e ikhethang ea anti-corrosion, le DIN 912 socket head cap screw geometry, e hlalosang moralo oa bona oa mochini le maemo a bona a boholo.

2. Dacromet Coating Technology

Dacromet ke thekenoloji e tsoetseng pele, e thehiloeng metsing, e sireletsang tikoloho e thibelang ho bola e entsoeng e le mokhoa o mong oa mokhoa o mong oa electroplating oa setso. Ke mokhoa o sa sebeliseng motlakase oa dip spin coating o entsoeng ka li-flakes tsa zinki tse ntle haholo, li-flakes tsa aluminium, metsoako ea chromic acid, le li-binders tse khethehileng tsa tlhaho. Ha li phekoloa ka mocheso o phahameng, likarolo tsena li etsa lesela le teteaneng, le nang le mefuta e mengata ea tšepe e kopanyang metallurgical ho substrate ea tšepe.

Ho fapana le electroplating e tloaelehileng, e itšetlehileng ka ho kenngoa ha electrolytic, Dacromet e sebelisa mokhoa oa dip-spin kapa dip-drain. Li-fasteners li qoelisoa ka har'a sekoaelo sa metsi sa Dacromet, ebe se kenngoa bohareng ho tlosa thepa e feteletseng, 'me qetellong se besoe ka likhato tse ka bang 300 tsa Celsius. Mokhoa ona oa ho folisa o etsa hore maqeba a zinki le aluminiamo a laminate le ho sinter hammoho, ho etsa lesela la silevera-gray, le khomarelang haholo le sireletsang.

Ts'ebetso ea ho roala ha Dacromet e na le mekhahlelo e 'maloa e laoloang ka hloko:

Mohato	Tshebetso	Tlhaloso
1	Ho fokotsa mafura	Ho tlosoa ha oli, litlolo, le litšila tse ka holim'a metsi ho sebelisoa lintho tse hloekisang alkaline
2	Ho phatloha ho hoholo	Ho hloekisa ka mechine ho tlosa mafome a sekala, mafome le oxide sebakeng sa fasteners
3	Dip-Spin Coating	Ho qoelisoa ka har'a mokelikeli oa Dacromet o lateloang ke ho bilika ha centrifugal ho laola botenya ba ho roala
4	Pheliso ea Pele	Ho baka ka likhato tse 80-120 tsa Celsius ho mouoane mongobo le ho theha filimi ea pele
5	Dip-Spin ea Bobeli	Sebaka sa boikhethelo sa bobeli sa ho roala bakeng sa tšireletso e matlafalitsoeng ea kutu
6	Pheliso ea ho Qetela	Ho baka likhato tse 280-320 tsa Celsius ho sinter zinc/aluminium flakes le ho theha lera la ho qetela la tšireletso.
7	Pholiso & Tlhahlobo	Pholiso e laoloang e lateloa ke tlhahlobo ea boleng bakeng sa botenya ba ho roala, ho khomarela le ponahalo

3. DIN 912 Socket Head Cap Screws

DIN 912 ke Tekanyetso ea Indasteri ea Jeremane e hlalosang boholo, mamello, le thepa ea mochini ea li-sccrews tsa hex socket head cap, tse tsejoang hape e le li-bolts tsa Allen kapa li-socket head cap screws. Li-fasteners tsena li na le hlooho ea cylindrical e nang le socket drive ea hexagonal, e etselitsoeng ho tsamaisoa ke Wrench ea Allen (senotlolo sa hex). Tekanyetso ea DIN 912 e amohetsoe ka bophara lefatšeng ka bophara mme e sebetsa ka ho lekana le ISO 4762.

Socket head cap screws li khetholloa ke karo-karolelano e phahameng ea matla ho isa ho boholo. Moralo oa hlooho ea cylindrical o lumella matla a holimo a ho koala ha a bapisoa le li-screw tse tloaelehileng tsa hex tsa bophara bo lekanang, athe hex drive e kahare e thusa ho kenya libakeng tse koaletsoeng tse nang le tumello e lekanyelitsoeng. Hlooho e dutse ka metsi kapa ka tlase ho bokahodimo ba ho nyalana ha e kentswe ka mokoting o nang le poropo, e fana ka ponahalo e hlwekileng, ya boemo bo tlase.

4. Melemo ea Synergistic: Dacromet + DIN 912

Ha seaparo sa Dacromet se sebelisoa ho li-screw tsa DIN 912 socket head cap, sephetho ke se tiisang se kopanyang ts'ebetso e ikhethang ea mochini le ts'ireletso e ikhethang ea kutu. Synergy ena e etsa hore "Dacromet-coated socket head cap" e be khetho e ratoang libakeng tse boima.

5. Qetello

Li-screws tse koahetsoeng ka Dacromet tsa DIN 912 tsa socket head cap li emela mateano a boenjineri bo tsoetseng pele le moralo o nepahetseng oa sehatsetsi. Ts'ebetso ea ho roala ha Dacromet e fana ka thibelo e matla, e ikarabellang tikolohong e fetang e tloaelehileng ea electroplating ka moeli o moholo, ha DIN 912 geometry e tiisa matla a ho koala, ho kenya letsoho ka mokhoa o babatsehang oa ho khanna, le ho kenya sebaka se sebetsang hantle.

Ka kopanelo, mahlale ana a hlahisa fastener e khonang ho sebetsa ka ts'epahalo maemong a boima haholo a indasteri. Ha liindasteri li ntse li tsoela pele ho batla bophelo bo bolelele ba ts'ebeletso, tlhokomelo e fokotsehileng, le ts'ebetso ea tlhahiso e lumellanang le tikoloho, li-screws tse koahetsoeng ke Dacromet li tla lula e le karolo ea bohlokoa boenjiniere le kaho lefatšeng ka bophara.

Bakeng sa lihlopha tsa ho reka le tsa boenjiniere, ho hlakisa li-screws tse koahetsoeng ke Dacromet-coated DIN 912 socket head cap li tiisa hore ho latela litekanyetso tsa machaba tsa ts'ireletso ea kutu ha ho ntse ho bolokoa ts'ebetso ea mochini e hlokahalang bakeng sa lits'ebetso tsa bohlokoa tsa polokeho.

Ha ke na. E latelang.
