Mtundu wachitsulo wophatikizika wa phenolic sangweji gulu la chipinda chozizira komanso kusungirako kuzizira

Ubwino wa thovu phenolic monga kutchinjiriza pachimake za mtundu zitsulo masangweji gulu

Phenolic thovu ndi njira yatsopano komanso yotetezeka yosungira kutentha komanso zinthu zopulumutsa mphamvu.Kachitidwe kake ndiukadaulo wopanga wafika pamlingo wapamwamba kwambiri padziko lonse lapansi.Ambiri, phenolic thovu monga kutchinjiriza pachimake za mtundu zitsulo masangweji gulu ali ndi makhalidwe abwino awa poyerekeza ndi zipangizo zina kutchinjiriza.
3.1 kwambiri kukana moto: organic matenthedwe zipangizo zotetezera monga polyurethane ndi polyphenylene zimatulutsa utsi wandiweyani ndi poizoni kwambiri pambuyo kuyaka, zomwe n'zosavuta kuchititsa imfa ndi kuonjezera zovuta kuzimitsa moto.The phenolic thovu siyakayaka moto.Kuchita kuyaka kumafika m'kalasi A, kutentha kwakukulu kwa utumiki ndi 180 ℃ (kutentha kovomerezeka nthawi yomweyo ndi 250 ℃), ndi kukana kwa lawi la 100 mm wandiweyani wa thovu la phenolic kumatha kufika kupitirira ola limodzi popanda kulowetsedwa.Pansi pa moto wachindunji, pali kuyika kwa kaboni, palibe kudontha, palibe kupindika komanso kusungunuka.Pambuyo pa kuyaka kwa moto, "graphite thovu" imapangidwa pamwamba, kuteteza bwino mawonekedwe a thovu mu wosanjikiza.
3.2 ntchito yabwino kwambiri yotetezera kutentha: kutentha kwapansi (< 0.025w / m × K. Ndikoposa kawiri kuposa polyphenylene ndipo ndi yofanana ndi polyurethane), yomwe ndi chinthu chabwino kwambiri chotetezera kutentha ndi insulatio.

Poyerekeza pomaliza: phenolic thovu kutchinjiriza sangweji wosanjikiza ali bwino matenthedwe kutchinjiriza zotsatira kuposa thanthwe ubweya, EPS, XPS ndi zipangizo kutchinjiriza ena, ndi wofanana polyurethane zakuthupi;Komabe, kukana moto kwa thovu la phenolic mwachiwonekere kuli bwino kuposa polyurethane, ndipo mtengo wake ndi wabwino kwambiri kuposa wa polyurethane.Chifukwa chake, potengera magwiridwe antchito, chithovu cha phenolic chimapambana.
