- 1.Q: Ntev npaum li cas tuaj yeem xa tuaj?
A: Rau cov khoom lag luam, yuav ua cov khoom xa tuaj hauv 5- 7 hnub tom qab tau txais qhov tso nyiaj lossis tau txais L / C; Rau cov khoom xav tau kev tsim khoom tshiab rau cov khoom siv, feem ntau ua cov khoom xa tuaj hauv 15-30 hnub; Rau cov khoom xav tau tshiab ntau lawm rau
cov ntaub ntawv tshwj xeeb thiab tsis tshua muaj, feem ntau xav tau 30-40 hnub ua zaub mov xa tuaj.
- 2.Q: Yuav Daim Ntawv Pov Thawj Ua Haujlwm puas tau lees paub rau EN10210, EN10219?
A: Rau cov khoom tsim tawm tshiab tsis tas yuav txiav lossis ua tiav, yuav muab Daim Ntawv Pov Thawj Zeb Xeem Xeem
tau ntawv pov thawj rau EN10210 (10219); rau cov khoom lag luam thiab cov khoom xav tau kev txiav lossis kev ua haujlwm ntxiv, yuav muab Daim Ntawv Pov Thawj Zoo ntawm peb Lub Tuam Txhab, Nws yuav qhia lub npe zeb thawj thiab cov ntaub ntawv qub.
- 3.Q: Thaum cov khoom tau txais pom tias tsis ua raws li cov khoom lag luam daim ntawv cog lus xav tau, koj yuav ua li cas?
A: Thaum cov khoom tau txais pom tias tsis ua raws li cov khoom lag luam daim ntawv cog lus, thaum tau txais cov duab thiab cov ntaub ntawv raug cai thiab cov ntaub ntawv los ntawm koj sab, yog tias nws tsis ua raws, peb yuav them rov qab qhov poob thaum thawj zaug.
- 4.Q: Koj lub sijhawm xa khoom ntev npaum li cas?
A: Feem ntau nws yog 5-10 hnub yog tias cov khoom muaj nyob hauv Tshuag. los yog nws yog 15-20 hnub yog tias cov khoom tsis nyob hauv Tshuag, nws yog raws li kom muaj nuj nqis.
- 5.Q: Koj puas muab cov qauv? puas yog dawb lossis ntxiv?
A: Yog, peb tuaj yeem muab cov qauv thiab tsis them tus nqi thauj khoom.
- 6.Q: Koj cov nqe lus them nqi yog dab tsi?
A: Them <= 1000USD, 100% ua ntej. Kev Them> = 1000USD, 30% T / T ua ntej, tshuav nyiaj li cas ua ntej xa zaub mov.
