Kodi bolodi yamatumbo imakhala ndi formaldehyde? Ubwino ndi Zovuta za Blish Board

Kuti matabwa atchini, abwenzi ambiri sakudziwa, ndi zojambula zodziwika bwino zomwe zimapangidwa mwaluso, osati zokhala ndi mawonekedwe ake , etc., chifukwa chake, kuti agwiritsidwe ntchito kwambiri pomanga, ndiye kuti pali formaldehde mu bladister ? Apa Tilongosola mwatsatanetsatane: Bodister Boardhyde ndi zabwino ndi zovuta za bolodi? Ndikuyembekeza kukuthandizani.

Kodi bolodi yamatumbo imakhala ndi formaldehyde?

Kodi pali formaldehyde mu chithumi ? Choyamba, pulasitiki yapamwamba yomwe ndi yopanda fungo, yopanda poizoni, yopanda fungo, komanso yowonekera kwambiri. Sizongokhala ndi zinthu zabwino, komanso zimakhalanso ndi zovuta zakutha, kutentha kwapamwamba kwambiri kukana, kutentha kwakanthawi kotsutsana, komanso kukhazikika kwakanthawi. Kugwiritsa Ntchito Kwakutali Kwa 60 ~ 120 ° C, Palibe malo ofunikira, adzakhala m'malo osungunula pa 220-230 ° C.

2. Kachiwiri, chifukwa cha kuuma kwake kwamphamvu, kusinthika kwakukulu, mayamwidwe ochepa amadzi, kukula pang'ono, komanso kukhazikika kwa mpweya, ndi zinthu zodetsa nkhawa.

3, pamapeto pake, Kuwala kumakhala kosakhazikika, koma osati Kuwala Kwamphamvu, kukana kwa nyengo yabwino, koma osalimba alkali, ngati nthawi yayitali m'madzi, kumapangitsa kuti hydrolysis mu madzi, kuwonjezera apo, kuvala kosavuta kukana .

Ubwino ndi zovuta za bolodi:

Choyamba, zabwino za bolodi yapulasitiki

1. Imagwiritsa ntchito bolodi yaukadaulo yosiyanasiyana ngati nthiti yaiwisi, ndipo mawonekedwe ake ndi osavuta kumetedwa. Itha kulinganiza njira yotopetsa ndi mphete pazinthu. Pambuyo poumba, imatha kuonetsa mitundu yosiyanasiyana ndi mawonekedwe atatu. Chifukwa chake, motero, wokondedwa ndi wokondedwa kwambiri ndi ogwiritsa ntchito.

2, mitundu yolemera, mizere yoyenera, yopanda maonekedwe, yopanda kanthu, yopanda kanthu, kuteteza pang'ono ndi zinthu zosavuta, ndi zinthu zosavuta zokhazikika, ndi zinthu zambiri zokhazikika.

3. Pakukapangidwe, mbali zinayi za malonda zimatha kusindikizidwa mu thupi limodzi ndi kufa, ndipo palibe chifukwa chosindikizira china. Chifukwa chake, mavuto monga kutsegulira kwa bolodi ndipo kutukula kumatha kuthetsedwa bwino.

Chachiwiri, Zovuta za Board Board

1, ntchito zokhazikika, koma osati Kuwala Kwambiri, Alkali, Ayinesi, Ketones ndi Osuma

2. Chifukwa cha kutopa kwake kolimba, madzi owundana nthawi yayitali amakonda hydrolysis ndi kusokonekera. Kuphatikiza apo, zosungunulira zake zotsutsana ndi abrasion zilinso osauka kwambiri, tiyenera kusankha mosamala, osati osawoneka bwino.

3, zinthu zoloweza kunja ndizokwera mtengo, koma zabwino zambiri zomwe sizimadutsa. Kuphatikiza apo, bolodi ya chiwindi imawopa kwambiri kutentha, ngakhale itakhala ndudu yaying'ono komanso imapangitsanso filimuyo.
