Txheej txheem txheej txheem: Sharping-Hardening-Edging cov hniav-Polishing-Coating &-hluav taws kub-Saib

Cov khoom siv stainless hlau rau rab chais yog ua tiav los ntawm lub tshuab nias. Cov khoom siv stainless hlau muaj chrome, uas ua rau nws nyuaj rau xeb, thiab ob peb % ntawm carbon, uas ua rau cov hniav tawv. Lub thickness ntawm cov khoom yog hais txog 0.1 hli. Cov ntaub nplaum zoo li no yog unrolled thiab tom qab txiav qhov nrog lub tshuab nias, nws yog dov rov qab. Ntau tshaj 500 daim ntawm rab chais hniav yog stamped tawm ib feeb.

Tom qab cov txheej txheem nias, stainless hlau tseem tuaj yeem khoov tau. Yog li, nws yog hardened los ntawm cua sov nws nyob rau hauv ib tug hluav taws xob rauv ntawm 1,000 ℃ thiab ces sai txias nws. Los ntawm kev ua kom txias dua ntawm -80 ℃, cov hlau tsis muaj zog yuav nyuaj dua. Los ntawm cua sov nws dua, lub elasticity ntawm stainless hlau nce thiab cov khoom yuav nyuaj rau tawg, thaum tuav nws thawj tsos.

Cov txheej txheem ntawm kev tsim cov npoo npoo los ntawm kev sib tsoo lub ntsej muag ntawm cov khoom siv stainless hlau tawv nrog whetstone yog hu ua "blade edging". Cov txheej txheem hniav no muaj nyob rau hauv thawj zaug sib tsoo cov khoom nrog ntxhib whetstone, tom qab ntawd sib tsoo nws ntawm lub kaum ntse ntse dua nrog lub nruab nrab whetstone thiab thaum kawg sib tsoo lub hau ntawm cov hniav siv lub finer whetstone. Cov txheej txheem ntawm kev ua kom nyias nyias cov ntaub ntawv ntawm lub kaum sab xis muaj qhov paub txog tias JiaLi cov chaw tsim khoom tau sau ntau xyoo.

Tom qab 3rd kauj ruam ntawm cov txheej txheem hniav edging, burrs (ragged npoo tsim thaum lub sij hawm sib tsoo) tuaj yeem pom ntawm cov lus qhia hniav. Cov burrs no yog polished siv tshwj xeeb strops ua los ntawm nyuj nkaum. Los ntawm kev sib txawv ntawm cov strops thiab txoj hauv kev siv lawv rau cov lus qhia hniav, nws muaj peev xwm tsim tau, nrog submicron raug, cov lus qhia hniav nrog cov duab zoo meej rau shaving thiab kom tau txais qhov zoo tshaj plaws sharpness.

Polished rab chais hniav raug muab cais ua ib daim ntawm cov theem no thawj zaug, ces, lawv yog bunched ua ke thiab skewered. Sab nraub qaum ntawm cov hniav muaj qhov zoo nkauj ntawm cov hlau tsis muaj steel, tab sis ntawm qhov tsis sib xws, cov hniav ntse ntse tsis cuam tshuam lub teeb thiab zoo li dub. Yog tias cov lus qhia ntawm cov hniav pom lub teeb, nws txhais tau tias lawv tsis muaj lub kaum ntse ntse txaus thiab lawv yog cov khoom tsis raug. Txhua rab chais hniav yog visually soj ntsuam nyob rau hauv no txoj kev.

Cov hniav zoo tshaj plaws yog coated nrog cov yeeb yaj kiab hlau tawv kom ua rau lawv nyuaj rau hnav. Cov txheej txheem no tseem muaj lub hom phiaj ua kom cov tswv yim hniav nyuaj rau xeb. Cov hniav yog ntxiv coated nrog fluorine resin, thiaj li tso cai rau lawv mus smoothly hla daim tawv nqaij. Tom qab ntawd, resin yog rhuab thiab melted los ua ib zaj duab xis ntawm qhov chaw. Qhov no ob txheej txheej zoo heev txhim kho lub sharpness thiab durability ntawm rab chais.
