Daim ntawv qhia, lossis lub tshuab ntawv pov ntawv, yog qhov xav tau thiaj li tsim cov ntawv luam ntawv tiav tsis yog nthuav tawm xwb, tab sis kuj yooj yim rau kev tuav, vim tias cov ntawv sib txuas rau hauv daim ntawv qhia tsis poob. Feem ntau, cov tshuab no siv los ntawm cov neeg ua haujlwm hauv chaw ua haujlwm kom khaws lawv cov ntawv qhia, nthuav tawm thiab lwm yam ntaub ntawv kom zoo nkauj thiab huv.
Ntau yam ntawm cov ntawv nthuav qhia
Phau ntawv qhia yuav tso cai rau koj los punch qhov nyob rau hauv ntau cov duab los ntawm lub voj voog mus rau ib tug duab plaub ntawm cov npoo ntawm cov ntawv. Cov ntawv thaiv no ces tau swb mus rau lub caij nplooj ntoo hlav. Muaj ob peb hom ntawv nthuav qhia:
- ua haujlwm nrog yas springs;
- ua haujlwm nrog hlau hlav;
- Cov ntawv qhia thermal;
- cov ntaub ntawv sib koom ua ke lossis suav daws.
Phau ntawv qhia rau phau ntawv qhia kev qhia
Muab lub tshuab tso rau saum rooj lossis txee. Npaj cov ntaub ntawv lossis ib daim thaiv ntawm cov ntawv yuav tsum tau hla nrog lub qhov txau. Tsis txhob hnov qab npaj cov ntaub npog uas yuav pab ua daim npog rau koj daim ntawv qhia, uas tuaj yeem yog duab los qhia lossis cov npog yas. Nco ntsoov tias thaum lub caij nplooj ntoo hlav tau nruab lawm, nws yuav tsis muaj qhov txuas ntxiv ntxiv rau daim ntawv.
Ua ntej, cov qhov yog tsim hauv daim ntawv nws tus kheej, i.e. cov ntawv txheeb yog perforated. Tom qab ntawd, cov haujlwm zoo sib xws tau ua nrog pob tshab lossis duab los qhia (npog). Yog tias daim ntawv muaj ntau tshaj li 25 daim ntawv (nrog daim ntawv tuab tsis ntau tshaj 125 grams tauj ib qhov cub ntsuas), nws raug nquahu kom faib nws ua ntau ntu thiab perforate rau txhua ntu sib cais, thaum soj ntsuam ncaj qha rau perforation tseev ciaj ciam.
Txog kev khi, koj yuav tsum nqa yas lossis hlau caij nplooj ntoos hlav, nyob ntawm seb tus ntawv twg koj muaj. Yog tias koj daim ntawv siv hlau caij nplooj ntoo hlav uas muaj zog tshaj lub caij nplooj ntoo yas, nco ntsoov tias koj yuav tsis muaj peev xwm tshem tawm cov ntawv uas tau khi nws los ntawm daim ntawv qhia. Tab sis thaum lub laj kab nrog lub caij nplooj ntoo yas yog siv, tom qab ntawd khi, nws yuav ua tau, yog tias tsim nyog, ntxiv cov nplooj ntawv los ntawm kev qhib lub caij nplooj ntoo hlav, txawm li cas los xij, nws cov tsos cuam tshuam loj heev.
Qhov loj ntawm lub caij nplooj ntoo hlav yog xaiv los ntawm cov naj npawb ntawm cov nplooj ntawv, tom qab ntawd nws tau muab tso rau ntawm lub zuag ntawm daim ntawv thiab qhib (txiv ntxawm). Tom qab ntawv ntawm cov ntaub ntawv muab tso rau hauv txhua pawg: thawj daim ntawv npog, tom qab ntawd daim ntawv nws tus kheej, tom qab ntawv thib ob thiab cov duab txuas mus. Yog li, thaum kawg koj tau txais daim ntawv zoo nkauj thiab nthuav tawm uas koj yuav tsis txaj muag xa mus rau koj tus thawj coj lossis koj cov koom ua lag luam. Ib qho ntxiv, cov ntawv qhia hauv tshuab muag khoom siv feem ntau yog siv los ntawm cov tub ntxhais kawm los tsim cov ntawv pov thawj kawm tiav lossis cov ntawv siv sij hawm.
