Rufin rufi - abu selection

Kafin fara rufi daga cikin rufi, kana bukatar ka sosai bincika daban-daban kayan amfani kamar yadda rufi daga cikin rufi, to san abũbuwan amfãni, disadvantages, kazalika da fannin aikace-aikace. Make da hakkin zabi za su taimake ka cusa wannan labarin ta nazari akai wanda ka daina bukatar shiga a Internet search engines tambaya game da abin da ya rufe rufin.

Yau kasuwar offers da damar da wata babbar selection na insulating kayan. A mafi kowa wadanda su ne: polystyrene da dutse ulu, kumfa gilashi, aerated kankare da m gilashin-fiber faranti. Bari mu ɗan yi nazarin wadannan jinsuna.

Ma'adinai ulu, ko kuma wajen, da mat, da farantin daga gare shi, shi ne a yau ya fi na kowa da irin. Thermal rufi daga cikin rufi tare da ma'adinai ulu iya gaskiya da za a dauke mafi kyau warware wannan matsala. Tun da shi yana mai low coefficient na thermal watsin (na 0,032 zuwa 0,045 W / m × K), mai kyau tururi permeability, sauti rufi, karko (game da 50 shekaru) kuma elasticity. Har ila yau, ta ba gaba daya ruwa sha da kuma shi yana da babban jure inji lalacewa. Kuma mafi muhimmanci alama na ma'adinai ulu - shi ne cewa shi yana da low flammability.

Kusan wannan halaye da kuma gilashin, ko da yake mai yawa fiye da ruwa sha da ruwa tururi watsa kudi ne sosai ƙananan. Don samun wannan sakamakon a matsayin daga ma'adinai ulu, yana yiwuwa ya rufe rufin dutse ulu, saboda ta Properties, shi ne sosai kama da kaddarorin da ma'adinai.

Rufin rufi extruded polystyrene kumfa iya kira kuma mai kyau wani zaɓi. Yana yana da wani low thermal watsin (0.02 zuwa 0,035 W / m × K), karamin nauyi da kuma, muhimmanci, da mun gwada low cost. Kara da cewa abun da ke ciki na musamman sinadaran ƙari sanya shi retardant da kuma kai-extinguishing abu. Akwai kuma rashin zuwa da irin wannan rufi, misali, mallaka wani sosai low ruwa tururi permeability cewa a lokacin da yadda ya kamata saka iska na iya haifar da ƙara zafi rufi tsarin. Har ila yau, polystyrene yana low elasticity kuma high elasticity cewa ba da damar yin amfani da abin da ake kira "yin rufi kek" ga shigarwa na wani hadadden rufin jeri.

A kan tushen da foamed robobi, akwai wani irin abu, wanda sau da yawa nuna rufi daga cikin rufi - a polyurethane kumfa. Its m halaye ne da wadannan: ƙãra jure lalatattu yanayi, m zafin aiki range (daga -180 zuwa +250 ° C). Disadvantages - shi ne m zuwa hasken rana kai tsaye, saboda abin da wajibi ne a yi wani m shafi. Wannan irin abu damar biyu da manna mechanically zuwa amince da shi to da ake so surface, da kuma gudanar da spraying. Yana kawai main iri foamed polymer abu, akwai wasu mutane da yawa.

Thermal rufi na rufin via sakamako microcameras, wanda suna cike da iska, yiwu inorganic abu wanda ake kira salula kankare. Eh, mana, babu shakka za a iya dangana ga "jiya ta yini." Amma da amfani da kwayoyin fiber rufi, wadda ake bisa toshe kwalaba, yana da kusa-lokaci na gaba na yi fasaha. Amma a yau shi ne mai wuce yarda da tsada da yardarSa.
