Dab tsi yog cov yam ntxwv uas cuam tshuam rau kev ua haujlwm ntawm Flanges loj
Jun 06, 2022
Muaj ntau yam cuam tshuam rau kev ua haujlwm ntawm flanges loj. Ib qho yog qhov kub thiab txias (annealing kub yog qhov ntsuas kub ntawm cov primers thiab lub sij hawm sib cais template). Thaum 50 feem pua ntawm cov primers thiab cov sib txuas ntxiv yog ob-stranded DNA molecules, qhov kub thiab txias yog qhov tseem ceeb cuam tshuam rau qhov tshwj xeeb ntawm PCR.
Qhov zoo tshaj plaws, qhov kub ntawm qhov annealing yog qis dua rau kev ua haujlwm zoo ntawm cov txheej txheem primer, thiab tib lub sijhawm, qhov kub ntawm qhov annealing yog siab dua thiab tsis muaj kev sib cais tshwj xeeb yog txo. Tus txheeb ze tsim nyog annealing kub yog 55 degree ~ 70 degree, thiab primer annealing kub yog 5 degree qis dua li ntawm TM.
Koj puas tuaj yeem tau txais qhov kub thiab txias. Kev kho cua sov ntawm cov flanges loj feem ntau yog siv, uas yog, qhov kub ntawm 1040 Tsawg dua lossis sib npaug rau 1120 degree (Japanese standard) feem ntau hu ua "annealing".
Qhov thib ob, lub qhov cub tawg (steel phaj thiab welded steel plhaub, siv steel-rau-steel vuam trolley, lub trolley txo cov cua sov los ntawm hluav taws xob thiab convection mos kev sib cuag nrog lub hauv ob sab phlu thiab sanding sealing ntaus ntawv, zoo txhim kho sealing kev ua tau zoo ntawm lub cub tawg. Ci ntsa iab annealing rauv raug kaw thiab cais tawm ntawm huab cua sab nraud; tsuav yog qhov chaw nres nkoj tso tuaj yeem dhau mus (rau igniting cov pa tawm hydrogen) yuav tsum tau siv los ua kev tu hydrogen. Lub tshuab hluav taws xob, qhov chaw nruab nrab ntawm lub qhov cub annealing Nws yog qhov nruab nrab ntawm cov kav dej thiab qhov nruab nrab ntawm lub qhov hluav taws xob cov yeeb nkab, lub nplhaib sealing nyob rau hauv qhov chaw yog tshwj xeeb tshaj yog yooj yim rau hnav thiab yuav tsum tau kuaj xyuas thiab hloov ntau zaus. Txhawm rau kom tsis txhob muaj cov kab mob micro-kua, lub cub tawg tu roj yuav tsum tswj kom muaj lub siab zoo, yog tias nws yog hydrogen tu Gas, feem ntau xav tau ntau tshaj 20 kbar.
