Soft solder feem ntau muaj qhov sib txawv ntawm 90 txog 450 ° C (190 txog 840 ° F; 360 txog 720 K), thiab feem ntau siv hauv hluav taws xob, kav dej, thiab cov ntawv hlau ua haujlwm. Alloys uas yaj ntawm 180 thiab 190 ° C (360 thiab 370 ° F; 450 thiab 460 K)yog cov siv ntau tshaj plaws.
Nyob qhov muag muag siv rau dab tsi?
Nyob zoo. Cov khoom muag muag yogcov txheej txheem siv tau rau kev koom nrog cov hlau ntawm ntau hom, tshwj xeeb tshaj yog cov khoom me me uas yuav tau deformed lossis puas nrog cov txheej txheem kub dua. Cov txheej txheem piav qhia ntawm no yog siv lub teeb hluav taws xob ua kom sov.
Thaum twg koj yuav siv tawv soldering es tsis txhob muag muag?
Hard Solder yog Stronger
Nyuaj soldering tsim ib daim ntawv cog lus muaj zog dua piv rau cov muag muag thiab koom nrog kub dua los yaj cov khoom siv. Cov khoom no feem ntau yog tooj dag lossis nyiaj thiab yuav tsum tau siv lub tshuab ziab khaub ncaws kom yaj.
Koj xav tau dab tsi rau qhov muag muag?
Soft soldering, tseem hu ua stained iav style, yuav tsum muaj cov hauv qab no: a soldering hlau, solder, flux, qhov chaw ua haujlwm tsim nyog, cov ntaub ntawv siv cov khoom siv rau, cov khoom yuav tsum tau koom los yog accented nrog nyiaj-xim xim solder thiab ib tug tu tus neeg saib xyuas.
Yuav ua li cas cov khoom raug soldered?
Soldering muab qhov tsim nyog ruaj khov tab sis thim rov qab kev sib txuas ntawm cov kav dej tooj liab hauv cov kav dej thiab cov pob qij txha hauv cov khoom siv hlau xws li cov kaus poom zaub mov, lub ru tsev flashing, nag gutters thiab tsheb radiators.

Rau qhov kev ua ub no yog cov txheej txheem oxidative feem ntau siv?
Cov kab mob oxidative, thawj qhov chaw ntawm ATP thaum so thiab thaum lub sijhawm ua haujlwm qis, siv feem ntau carbohydrates thiab rog li substratesUa raws li qhov pib ntawm kev ua, raws li kev siv ntawm Kev tawm dag zog nce ntxiv, muaj kev hloov pauv hauv substrate nyiam los ntawm cov rog mus rau carbohydrates .
Leej twg feem ntau nthuav tawm qhov kev thov rau cov neeg muag khoom?
Koj nyuam qhuav kawm 10 nqe lus! Npaj Kev Tshaj Tawm Tsis txhob qhia tus nqi ntawm qhov kev thov thiab muab kev nthuav qhia hauv xov tooj. Feem ntau tus neeg sawv cev sau npe nthuav tawm qhov kev thov rau cov neeg muag khoom . Koj tus neeg saib vaj tsev puas muab koj qhov kev thov rau tus neeg muag khoom?
Puas yog feem ntau cuam tshuam los ntawm cov khoom siv organic?
Cov lus teb raug yog - a. av xim. Txawm hais tias txhua yam ntawm cov av hloov pauv thaum qhia txuas ntxiv mus rau ntau cov khoom siv organic, qhov kev hloov pom tau tshaj plaws yuav yog xim av . Vim li cas cov khoom siv organic hauv av tseem ceeb?
Thaum cov neeg muag khoom muag npe rau cov khoom muag?
Ib tug tub lag luam wholesale ua haujlwm hauv cov saw hlau ntawm cov neeg tsim khoom thiab cov khw muag khoom. Qee cov lag luam wholesale tsuas yog npaj cov khoom txav ntawm cov khoom es tsis txav cov khoom lawv tus kheej. Cov neeg ua lag luam kev lag luam txwv tsis pub cov neeg lag luam coj lub npe rau cov khoom muag thiab xav tias kev pheej hmoo koom nrog kev ua haujlwm ywj pheej Thaum cov neeg muag khoom nqa lub npe rau cov khoom muag thiab them tus nqi ntawm tub sab
Cov lus teb ntau qhov kev xaiv twg yog feem ntau?
Ntawm qhov kev xeem nrog plaub qhov kev xaiv (hais, A, B, C, thiab D), B yog me ntsis yuav raug (28%). Nco ntsoov, qhov kev cia siab ntawm txhua qhov kev xaiv yuav raug yog 25%. Thiab ntawm cov kev xeem nrog tsib txoj kev xaiv (hais, A, B, C, D, thiab E), Eyog cov lus teb uas feem ntau raug (23%) .
