Cov khoom siv ntawm cov hniav ntawm cov khoom noj khoom haus ncaj qha txiav txim siab txog kev siv tus nqi, kev ua haujlwm slicing, thiab kev nyab xeeb ntawm zaub mov. Raws li kev txiav txim siab tseem ceeb hauv kev yuav khoom, nws yog ib qho tsim nyog yuav tsum tau xaiv cov qauv raws li kev ua haujlwm ntawm tus kheej, batch yuav tsum tau ua, thiab kev ua raws cai. Cov hauv qab no yog cov lus qhia txog kev yuav khoom kom raug kom tsis txhob muaj kev pheej hmoo ntawm kev yuav khoom thiab txhim kho tus nqi- kev ua tau zoo.
1. Ua ntej qhov kev lees paub ua raws cai thiab tuav cov kab hauv qab ntawm kev nyab xeeb. Thaum yuav khoom, cov neeg muag khoom yuav tsum tau muab cov khoom noj khoom haus GB 4806 series -qib xeem cov ntaub ntawv kom paub meej tias cov ntaub ntawv ua tau raws li cov qauv ntawm cov ntaub ntawv hlau nyob rau hauv kev sib cuag nrog cov zaub mov, kom tsis txhob muaj teeb meem xws li tsiv teb tsaws ntawm cov hlau ions thiab xeb los ntawm cov khoom tsis zoo, uas tej zaum yuav paug cov khoom xyaw zaub mov thiab cuam tshuam rau kev tsim khoom.
2. Precisely xaiv cov qauv raws li kev ua haujlwm scenarios thiab zam qhov muag tsis pom kev yuav khoom.
◆ Rau me me thiab nruab nrab- kev lag luam loj thiab siv tsawg- zaus ua haujlwm (xws li cov tsev noj mov me me, cov khw muag khoom yooj yim), qhov tseem ceeb yuav tsum tau muab rau 4Cr13 stainless hlau, uas muaj qhov sib npaug hardness thiab toughness, kev ua haujlwm siab, yog tsim rau slicing txiv hmab txiv ntoo, zaub thiab zaub mov zoo tib yam, thiab yooj yim los ntxuav nrog tus nqi qis;
◆ Rau cov chav ua noj thiab cov chaw ua zaub mov loj uas muaj siab - zaus ua haujlwm tas li (xws li cov nqaij khov, batch huv zaub), xaiv 440C stainless hlau los yog siab - steel ceev, uas muaj cov hardness siab thiab muaj zog hnav tsis kam, txo qhov zaus ntawm cov hniav hloov;
◆ Rau kev ua cov khoom xyaw mos xws li txiv tsawb thiab txiv nkhaus taw, qhov tseem ceeb yuav tsum tau muab rau cov khoom siv nrog DLC lossis titanium nitride txheej, uas yog los tiv thaiv -stick thiab tiv thaiv kom tsis txhob lo rau riam, ua kom muaj kev ncaj ncees ntawm cov hlais.
3. Ua tib zoo saib xyuas cov ntsiab lus tseem ceeb thiab zam cov cuab yeej khoom. Tsom ntsoov rau kev tshuaj xyuas qhov hardness ntawm cov khoom (HRC50-60 yog qhov tsim nyog). Yog hais tias lub hardness tsis txaus, nws yog ib qho yooj yim rau dov cov hniav, blunt, thiab yooj yim rau vau yog hais tias lub hardness siab dhau heev lawm. Nyob rau tib lub sijhawm, xyuam xim rau qhov smoothness ntawm qhov chaw, uas yooj yim rau kev ntxuav thiab tshuaj tua kab mob, thiab zam kev khaws cia ntawm cov zaub mov seem. Tsis lees txais cov khoom qis- nqi thiab qis dua 3Cr13 cov ntaub ntawv (yooj yim rau xeb thiab ua haujlwm tsis zoo), thiab kev siv mus sij hawm ntev yuav nce nqi.
4. coj mus rau hauv tus account lub zog ntawm cov neeg muab khoom thiab xyuas kom ua raws li -cov kev pabcuam. Qhov tseem ceeb yog muab rau kev xaiv cov neeg muag khoom tsim nyog thiab muaj npe nrov, lees paub cov khoom muag txaus thiab xa khoom raws sijhawm, thiab ua tib zoo saib tom qab- muag (xws li cov hniav sib tsoo thiab hloov cov kev taw qhia) kom tsis txhob cuam tshuam rau kev tsim khoom vim muaj teeb meem ntawm cov hniav hloov.
