Mapaipi a utsi a Range Hoods!

Mapaipi a utsi a Range Hoods!

Nthawi zambiri pali mitundu itatu ya mapaipi a utsi amitundu yosiyanasiyana:flexible aluminium zojambulazo mpweya ma ducts, mapaipi a polypropylene (pulasitiki) ndi mapaipi a PVC. Mapaipi opangidwa ndi PVC si ambiri. Mipope yamtunduwu nthawi zambiri imagwiritsidwa ntchito ngati chitoliro chachitali ngati mita 3-5. Utsi wotulutsa utsi wa chitoliro cha mtunda ukadali wabwino kwambiri.

Pali mapaipi awiri wamba, flexible aluminium zojambulazo mpweya duct ndi polypropylene chitoliro. Kunena zowona, ena opanga machubu opangidwa ndi aluminiyamu wamba ndiafupiatali, ndipo machubu a polypropylene (pulasitiki) nthawi zambiri amakhala otalikirapo. Zonse mwazonse ndizokhudza kupanga phindu.

Ubwino wa chubu cha aluminium zojambulazo ndikuti ndi opaque, mosasamala kanthu za kuchuluka kwa mafuta omwe ali kunja, adzawoneka "oyera". Kachiwiri, kukana kwa kutentha kwa ma ducts osinthika a aluminiyamu omwe amapangidwa ndi mpweya ndikwabwino kuposa zopangira zitoliro za pulasitiki. Ubwino wa chubu la polypropylene ndikuti ndi losavuta kusamalira ndikusintha. Malumikizidwe akutsogolo ndi kumbuyo amakhomedwa kuti asungunuke mosavuta, koma ndi chubu chowonekera. Choncho, kuipa kwa mapaipi apulasitiki ndi owonekera komanso osavuta kupeza kuti chitoliro cha utsi ndi chodetsedwa, chomwe chimayambitsa "zosaoneka bwino"; chachiwiri ndi kukana kutentha, kukana kutentha kwa polypropylene si kolimba ngati kusinthasintha kwa ma ducts a aluminium zojambulazo, 120 ° C okha, koma izi sizoyenera kutulutsa mafuta amtundu wa hood. Ndiwoyenerera kwathunthu.

Mwachidule, ponena za momwe ntchito imagwiritsidwira ntchito: machubu a aluminium zojambulazo ndi ofanana ndi machubu a polypropylene; aesthetics: machubu a aluminiyamu zojambulazo ndi abwino kuposa machubu a polypropylene; ponena za kukana kutentha: machubu a aluminium zojambulazo ndi abwino kuposa machubu a polypropylene; kumasuka: machubu a polypropylene ndi abwino kuposa machubu a polypropylene mu machubu a aluminiyamu zojambulazo.
