High Borosilicate iav Test Tube

Ib, Introduction

High borosilicate iav test raj yog dav siv nyob rau hauv lub chaw soj nstuam vim lawv zoo heev kub tsis kam, tshuaj tsis kam, thiab pob tshab. Lawv tuaj yeem tiv taus qhov kub thiab txias thiab tiv taus cov tshuaj feem ntau, uas ua rau lawv zoo tagnrho rau ntau yam kev tshawb fawb thiab kev kho mob. Hom iav no yog tsim los ntawm cov feem pua ​​​​ntawm boron oxide, uas txhim kho nws cov khoom siv dag zog, thermal stability, thiab tshuaj tiv thaiv. Hauv tsab xov xwm no, peb yuav qhia txog cov yam ntxwv, kev tsim khoom, thiab kev siv cov iav borosilicate iav siab.

2, Cov yam ntxwv

High borosilicate iav kuaj cov raj tuaj yeem tiv taus qhov kub thiab txias hloov yam tsis muaj kev tawg lossis tawg. Lawv tuaj yeem tiv taus txog 500 degree yam tsis muaj deforming, uas ua rau lawv haum rau cua sov, txias, thiab kom tsis muaj menyuam. Lawv kuj muaj cov tshuaj tiv thaiv zoo heev thiab tuaj yeem tiv taus cov kua qaub, alkali, thiab cov kuab tshuaj organic. Cov cuab yeej no ua rau lawv zoo tagnrho rau khaws cia thiab sib tov ntau yam tshuaj hauv chav kuaj.

High borosilicate iav test tubes kuj yog pob tshab thiab muaj qhov ntsuas qis qis. Cov cuab yeej no ua kom cov qauv hauv lub raj pom thiab tuaj yeem pom nyob rau hauv qhov sib txawv ntawm lub teeb. Lub khob kuj yog ib qho yooj yim los ntxuav, kom tsis muaj menyuam, thiab rov siv dua, uas ua rau nws muaj txiaj ntsig zoo rau kev sim kuaj.

3, Cov txheej txheem tsim khoom

Kev tsim cov txheej txheem ntawm siab borosilicate iav kuaj raj yog ib qho nyuaj. Cov txheej txheem pib nrog cov khoom siv raw, uas suav nrog silica, boron oxide, thiab lwm yam tshuaj. Tom qab ntawd cov sib tov yog yaj nyob rau hauv ib lub qhov cub ntawm qhov kub thiab txias ntawm ib ncig ntawm 1500 degree. Cov txheej txheem hu ua fusion melting thiab yog siv los tsim iav nrog cov tshuaj zoo heev thiab thermal stability.

Tom qab melting qhov sib tov, cov kua yog poured rau hauv pwm thiab tso cai rau txias rau chav tsev kub. Lub iav yog tom qab ntawd los ntawm lub tshuab txiav los yog lub tshuab dov los tsim cov raj ntawm qhov sib txawv thiab cov duab. Lub iav yog ces annealed los txo cov kev ntxhov siab nyob rau hauv lub khob thiab txhim kho nws cov neeg kho tshuab zog. Tom qab ntawd cov tub ntxhais kuaj ua tiav raug ntxuav, sau npe, thiab ntim khoom xa tuaj.

4, Daim ntawv thov

High borosilicate iav xeem raj muaj ntau yam kev siv hauv chav kuaj. Lawv tuaj yeem siv rau khaws cia, hloov pauv, sib xyaw, thiab cua sov ntau yam tshuaj hauv chav kuaj. Lawv kuj tuaj yeem siv los ua cov hlab ntsha rau cov tshuaj tiv thaiv thiab npaj cov kab lis kev cai hauv kev sim microbiology.

High borosilicate iav test raj kuj tseem siv rau hauv daim ntawv thov kev kho mob, xws li kev sau ntshav thiab coj mus kuaj. Lawv kuj tau siv rau hauv kev lag luam zaub mov thiab dej haus ua lub khob ntim rau kev khaws cia thiab kev thauj mus los. Cov tshuaj tiv thaiv zoo heev thiab pob tshab ntawm iav ua rau nws tsim nyog rau ntim thiab khaws cia ntau yam khoom noj thiab dej haus.

5, Xaus

High borosilicate iav kuaj cov raj yog ib qho tseem ceeb hauv cov chaw soj nstuam vim lawv cov tshuaj tiv thaiv zoo heev, tiv thaiv tshav kub, thiab pob tshab. Lawv yog siv nyob rau hauv ntau yam kev siv, los ntawm kev khaws cia thiab hloov tshuaj mus rau kev kho mob thiab zaub mov kev siv. Cov txheej txheem tsim khoom ntawm high borosilicate iav test tubes yog complex, tab sis cov khoom tiav yog heev ruaj thiab siv tau yooj yim. Nrog nws cov khoom zoo heev, siab borosilicate iav kuaj raj yuav txuas ntxiv ua lub luag haujlwm tseem ceeb hauv kev tshawb fawb thiab kev tsim kho thev naus laus zis.
