Dab tsi yog iav chemical tempered?

I. Kev txhais thiab qhov zoo

Tshuaj tempered iav yog ib yam tseem ceeb ntawm prestressed iav. Txhawm rau txhawb nws lub zog, peb feem ntau siv cov tshuaj los yog lub cev txoj hauv kev los tsim kev ntxhov siab ntawm cov iav nto. Thaum lub iav dais sab nraud quab yuam, nws ua ntej offsets qhov kev ntxhov siab ntawm qhov chaw- qhov no tsis yog tsuas yog txhim kho lub load- cov kabmob muaj peev xwm tab sis kuj tseem txhim kho lub iav 'tus kheej cua siab ua haujlwm, kub tsis kam, cuam tshuam, thiab lwm yam.

Muaj plaub qhov zoo ntawm cov tshuaj tempered iav:

1. Nws lub zog yog 5 mus rau 10 npaug siab dua li cov iav zoo tib yam. Lub zog khoov yog 3 mus rau 5 npaug ntawm cov iav zoo tib yam, thiab qhov cuam tshuam lub zog yog 5 mus rau 10 npaug siab dua. Thaum ua kom muaj zog, nws kuj txhim kho kev nyab xeeb. Piv nrog rau iav ntawm tib lub thickness, tshuaj tempering yog obviously zoo dua lub cev tempering nyob rau hauv cov nqe lus ntawm lub zog.

2. Kev nyab xeeb hauv kev siv yog qhov zoo thib ob ntawm tempered iav. Nws nce load-cov kabmob muaj peev xwm txhim kho nws qhov tsis yooj yim. Qhov tsis kam mus rau qhov kub thiab txias hloov ntawm cov tshuaj tempered iav yog 2 mus rau 3 npaug siab dua li ntawm cov iav zoo tib yam. Feem ntau, nws tuaj yeem tiv taus qhov kub ntawm qhov sib txawv ntawm ntau tshaj 150 degree, uas muaj qhov cuam tshuam tseem ceeb ntawm kev tiv thaiv thermal tawg, thiab tsis muaj qhov tawg kiag li.

3. Vim muaj cov txheej txheem ua haujlwm sib txawv, cov khoom siv tempered tsis muaj deformation txhua yam -lawv yuav tsis hloov cov khoom zoo, thiab tsis muaj kev txwv rau cov khoom zoo li; txhua yam tuaj yeem ua rau tempered. Piv txwv li, nkhaus, cylindrical, lub raj mis -zoo li tus, lub thawv- zoo li tus, thiab tiaj tus- iav zoo li tuaj yeem ua tiav yam tsis muaj deformation.

4. Nws muaj qhov cuam tshuam tseem ceeb ntawm cov khoom siv ultra- nyias. Cov cuab yeej uas twb muaj lawm yog cov paub tab heev, thiab cov nyhuv tempering yog zoo heev rau iav nrog lub thickness ntawm 0.2 mus rau 5.0 hli, tsis ua rau bending deformation.

II. Manufacturing Principple

Chemical tempered iav yog tsim los siv cov txheej txheem kev sib pauv ion qis. Qhov thiaj li-hu ua qhov ntsuas kub qis yog hais txog qhov sib pauv qhov ntsuas kub tsis tshaj lub iav hloov pauv kub, uas yog txheeb ze rau qhov siab -kub ion txauv txheej txheem uas ua haujlwm siab tshaj qhov hloov pauv kub thiab qis dua qhov muag muag.

Lub hauv paus ntsiab lus yooj yim ntawm qhov qis -kub ion txauv txheej txheem yog: nyob rau hauv ib qho alkali ntsev tov nyob ib ncig ntawm 400 degree, cov ions nrog me radii nyob rau hauv lub iav txheej txheej yog pauv nrog ions nrog loj radii nyob rau hauv cov tshuaj. Piv txwv li, lithium ions nyob rau hauv iav yog pauv nrog poov tshuaj los yog sodium ions nyob rau hauv cov tshuaj, thiab sodium ions nyob rau hauv lub khob yog pauv nrog poov tshuaj ions nyob rau hauv cov tshuaj. Qhov sib txawv ntawm qhov ntim ntawm alkali ions tsim ib qho kev ntxhov siab compressive rau ntawm iav nto.

Tus naj npawb ntawm cov ions loj embedded rau hauv iav nto yog proportional rau saum npoo compressive kev nyuaj siab, yog li tus naj npawb ntawm ion exchanges thiab qhov tob ntawm lub exchanged nto txheej yog cov cim tseem ceeb ntawm lub zog. Txij li thaum cov txheej txheem ion txauv tau zoo ib yam, cov txheej txheem tshuaj tempering iav muaj qhov cuam tshuam tseem ceeb ntawm kev ntxiv dag zog rau cov iav nyias, tshwj xeeb tshaj yog tsim rau ntxiv dag zog iav nrog lub thickness tsawg dua 5 hli.

III. Daim Ntawv Thov Scope

Chemical tempered iav yog tsim rau siv nyob rau hauv cov nram qab no architectural thiab industrial scenarios: qhov chaw uas yuav tsum tau yuag txo, thaum muaj tej yam yuav tsum tau rau tej lub zog, dabtsi yog khoov zog, thiab kuj rau thermal shock. Piv txwv xws li: xov tooj ntawm tes npo iav npog, lub computer thiab TV screen iav, qhov chaw shuttles, fighter dav hlau movable npog, chav ua noj txee iav, hniav iav, hluav taws xob vaj huam sib luag iav, qhov rais thiab qab nthab ntawm cov tsev cog khoom ua liaj ua teb, qhov rooj thiab qhov rais iav ntawm lub tsev txawb, thiab hais txog.

Nrog rau cov txheej txheem kev paub tab, ultra- siv hluav taws xob tsawg, thiab siab - cov khoom zoo, nws tau dhau los ua ib qho kev siv tshuaj tempering rau ntau cov khoom.
