Kodi K ndi chiyani?
K-value ndi shorthand chabe pa matenthedwe matenthedwe.Thermal conductivity, n: kuchuluka kwa nthawi ya kutentha kwanthawi zonse kumayenda kupyola mugawo la chinthu chofanana chomwe chimapangitsidwa ndi kutentha kwa unit molunjika kuderali.
Kodi mumawerengera bwanji mtengo wa k?
Atha kuwerengedwa ngati 1 / (chiwerengero cha kukana kwa magawo osiyanasiyana a chinthucho (makhalidwe ake a R) + kukana kwamkati ndi kunja kwa chinthucho).
Kodi pali mitundu yosiyanasiyana ya PVC?
Pali mitundu iwiri yodziwika bwino ya chitoliro cha PVC - ndondomeko 40 PVC ndi ndondomeko 80 PVC.Ndandanda 40 PVC kawirikawiri woyera mu mtundu ndi ndondomeko 80 nthawi zambiri imvi mdima (iwo angapezeke mu mitundu ina).Kusiyana kwawo kwakukulu, komabe, ndiko kupanga kwawo.Ndandanda 80 chitoliro chapangidwa ndi khoma wandiweyani.
Kodi UPVC imagwiritsidwa ntchito chiyani?
UPVC, yomwe imadziwikanso kuti Unplasticized Polyvinyl Chloride, ndi zomangira zosasamalidwa bwino zomwe zimagwiritsidwa ntchito m'malo mwa matabwa opakidwa utoto, makamaka mafelemu a zenera ndi ma sill poika zowulira kawiri m'nyumba zatsopano, kapena kusintha mawindo akale omwe amawala.
Kodi mumawerengera bwanji mtengo wa k?
Kuti muwerenge K-Value ya insulation, ingogawani makulidwe (mu mainchesi) ndi R-Value.
Kodi mtengo wa K ndi chiyani?
K-value ndi shorthand chabe pa matenthedwe matenthedwe.Thermal conductivity, n: kuchuluka kwa nthawi ya kutentha kwanthawi zonse kumayenda kupyola mugawo la chinthu chofanana chomwe chimapangitsidwa ndi kutentha kwa unit molunjika kuderali.Tanthauzo ili siliri lovuta kwambiri.
Kodi K mu mamasukidwe akayendedwe?
K mtengo (kukhuthala), ndi chizindikiro chowoneka chogwirizana kwambiri ndi kukhuthala kwamkati, komwe nthawi zambiri kumatanthauzidwa mwanjira zosiyana pang'ono m'mafakitale osiyanasiyana kuwonetsa kukhuthala kutengera kuyerekezera kwa mamolekyu azinthu za polymeric zomwe zimagwiritsidwa ntchito makamaka pa PVC.
Kodi mankhwala opangira PVC ndi chiyani?
PVC ndi Polyvinyl Chloride.Ili ndi pulasitiki lomwe lili ndi zinthu zotsatirazi: CH2=CHCl (onani chithunzi kumanja).Pulasitiki imakwirira zinthu zambiri zopangidwa ndi polymerization kapena semi-synthetic polymerization (mwachitsanzo, ma molekyulu a carbon-based "organic" atalitali) omwe dzina limatanthawuza kuti mu semi-madzimadzi…
Kodi Chemical reaction ya PVC ndi chiyani?
PVC imapangidwa pogwiritsa ntchito njira yotchedwa Kuwonjezera polymerization.Izi zimatsegula zomangira ziwiri mu vinyl chloride monomer (VCM) kulola mamolekyu oyandikana nawo kuti alumikizane ndikupanga mamolekyu aatali.nC2H3Cl = (C2H3Cl)n vinilu kloridi monoma = polyvinylchloride
Kodi mawonekedwe a PVC ndi otani?
Zakuthupi ndi zamakina: PVC ndi polima atactic ndipo chifukwa chake imakhala yosasinthika.Komabe, nthawi zina zimachitika kuti, kwanuko, pazigawo zazifupi za unyolo, PVC ndi syndiotactic ndipo imatha kuganiza gawo la crystalline, koma kumeta ubweya wambiri sikudutsa 10 mpaka 15%.Kuchulukana kwa PVC ndi 1.38 g/cm3.
