Cov ntaub ntawv twg yog siv rau pins?

Pins, raws li kev sib txuas tsis tau muaj kev sib txuas hauv cov khoom siv hauv txhua yam, nqa cov cwj pwm tseem ceeb xws li kev kho, muab kev hloov pauv. Txhawm rau kom ntseeg tau tias cov pins tuaj yeem ua tau stably hauv ntau qhov chaw ua haujlwm, nws yog ib qho tseem ceeb rau xaiv cov khoom zoo. Cov hauv qab no yog ob peb cov ntaub ntawv siv tau siv rau cov nyiaj dav dav:

 

1. Tsawg Cov Hlau Hlau

Tsawg cov roj carbon hlau yog ib qho ntawm cov khoom siv uas nquag siv rau hauv Pin tsim khoom. Cov hlau no muaj cov ntsiab lus muaj roj carbon tsawg, yog li nws muaj cov ntsej muag zoo thiab muaj zog thiab yooj yim rau cov txheej txheem thiab cov duab. Nyob rau tib lub sijhawm, lub zog thiab hardness thiab hardness ntawm cov roj av tsawg yog qhov nruab nrab, uas tuaj yeem ua tau raws li qhov xav tau ntawm cov kev pab cuam tshuam. Tsis tas li ntawd, tus nqi ntawm cov roj carbon hlau tsawg yog tsawg, ua cov roj av tsawg, ua cov roj carbon steel muaj cov txiaj ntsig siab zoo hauv kev ua lag luam.

 

2.Medium Steel Hlau

Cov pa roj carbon steel piv nrog cov hlau qis, cov ntsiab lus carbon, yog li muaj zog ntxiv, yog li nws lub zog thiab hardness kuj tau nce raws li. Nruab Nrab Carbon Steel pins tuaj yeem tiv thaiv ntau dua cov khoom thauj thiab cov kev cuam tshuam, thiab haum rau cov kev xav tau rau lub zog thiab hnav tsis kam. Txawm li cas los xij, kev ua kev ua tau zoo ntawm cov roj carbon steel yog cov neeg tsis muaj zog, thiab siab dua thiab kub dua thiab kev sib tw zoo dua qub.

 

3. Stainless hlau

Stainless hlau yog cov hlau uas muaj kev tiv thaiv corrosion zoo heev, uas tau siv dav hauv ntau qhov chaw noo noo. Stainless hlau pins tuaj yeem tiv thaiv lub yaig ntawm kev tshaj tawm xws li huab cua, dej, acid, thiab alkali. Nyob rau tib lub sijhawm, stainless hlau kuj muaj cov khoom siv zoo thiab tuaj yeem ua tau raws li kev yuav tsum tau ua haujlwm hauv kev ua haujlwm nyuaj.

 

4. Brass
Tooj dag yog tooj liab-zinc alloy nrog hluav taws xob zoo, thermal conductivity thiab corrosion tsis kam. Tooj dag pins yog siv dav hauv cov khoom siv hluav taws xob, xa hluav taws xob txuas ntxiv thiab lwm thaj teb. Brass muaj lub zog nruab nrab thiab lub hardness thiab yooj yim rau cov txheej txheem thiab nruab. Tsis tas li ntawd, tooj daj kuj muaj kev hnav tsis kam kam thiab kev sib txhuam, uas tuaj yeem ua kom tau txais kev pabcuam lub neej ntawm tus lej PIN.

 

Ntxiv rau cov ntaub ntawv ntau yam saum toj no, pins kuj tseem tuaj yeem ua tau los ntawm lwm cov ntaub ntawv hlau (xws li cov ntaub ntawv hlau, thiab lwm yam) roj hmab, thiab lwm yam. Cov ntaub ntawv tshwj xeeb no tuaj yeem muab cov txiaj ntsig tshwj xeeb zoo kom tau raws li qhov xav tau ntawm daim ntawv thov kev pabcuam tshwj xeeb.

 

Thaum xaiv tus lej PIN, nws yog ib qho tsim nyog yuav tsum muaj kev nkag siab ntau yam xws li kev xaiv ua haujlwm, nws tuaj yeem ua haujlwm rau qhov kev ntseeg tau thiab cov khoom siv hluav taws xob tag nrho.
