1.YHow ua cov txheej txheem (txheej txheem hlau) coj tus cwj pwm tsis kub?
Cov hlau phaj nws tus kheej yog cov khoom siv hlau, thiab nws cov khoom siv kub tsawg yog feem ntau cuam tshuam nrog "qhov kev cuam tshuam kub tsawg nyuaj" ntawm cov hlau. Qhov nyuaj ntawm cov hlau tsis tshua muaj carbon yuav maj mam tsawg dua thaum cov xaim ntawm pej xeem steel, uas muaj qhov qis qis-kub. Nyob rau hauv ib puag ncig tsawg -30 ib puag ncig sab saud -30 degree, lub zog ntawm cov hlau nws tus kheej yuav tsis ua "nkig thiab tawg yooj yim" vim yooj yim tawg.
2.How ua txheej txheem (txheej xim txheej) coj tus cwj pwm tsis zoo?
Cov txheej yog qhov tseem ceeb yog qhov tseem ceeb uas txiav txim siab seb cov xim steel phaj "yuav nkig":
Qhov txheej txheej feem ntau cov txheej txheem organic, thiab nws qhov kev hloov kub thiab txias tshaj plaws los ntawm lub xeev yooj yim thiab txias dua
3.Qhov dab tsi yog qhov sib txawv ntawm cov khoom muaj txiaj ntsig zoo thiab cov txiaj ntsig qis?
High-zoo txheej: TG yog tsawg. Hauv feem ntau cov chaw ntawm kuv lub teb chaws, txheej txheej tseem muaj peev xwm tswj tau thiab yuav tsis ua tus nplawm vim qhov kub tsawg.
Cov txheej txheej qis: TG yog siab. Nyob rau thaj chaw txias txias, cov txheej yuav ua britt vim tsawg-kub ua tawv. Yog tias nws raug rau sab nraud quab yuam nyob rau lub sijhawm no, nws yuav tawg lossis tev tawm.
4.What kev ceev faj yuav tsum tau coj los siv tiag tiag?
Them sai sai rau txheej txheej zoo
Thaum kev yuav khoom, muab qhov tseem ceeb rau cov huab cua sov-tiv thaiv, uas muaj cov khoom kub zoo dua thiab haum rau qhov chaw txias teb chaws. Zam tsis txhob siv qis dua thiab cov khoom lag luam qis xim steel hlau.
Zam kev cuam tshuam sab nraud ntawm tsawg kub
Txawm hais tias rau cov paib zoo xim hlau, cov tawv ntawm cov txheej thiab substrate yuav txo qis me ntsis ntawm qhov qis qis heev. Nyob rau lub sijhawm no, cov khoom hnyav thiab kev kub ntxhov yuav tsum zam kom tiv thaiv kom tsis txhob muaj cov txheej los yog kev puas tsuaj.
Khij cov txheej txheej txheej xwm tsis tu ncua:
Tom qab lub caij ntuj no nyob rau hauv cov cheeb tsam qaum teb, tshuaj seb puas muaj kev tawg lossis ua cov tev ntawm cov txheej ntawm cov npoo ntawm cov xim hlau phaj. Yog tias pom kev puas tsuaj, kho nws nrog cov xim kho tshwj xeeb hauv lub sijhawm
5.Txoj ib puag ncig, ib puag ncig puas muaj qhov cuam tshuam loj tshaj plaws rau cov hlau xim-txheej hlau?
Hauv feem ntau thaj chaw (lub caij ntuj sov kub tshaj lossis sib npaug ntawm -30 qib
Tsuas yog nyob rau hauv tsawg kawg nkaus (xws li hauv qab - 40 degree, tab sis thaum siv cov xim hlau steel) nws tus kheej tsis yooj yim los ua qhov kub thiab txias.
