UMGAQO-NKQUBO WOKUVAVANYA: GB / T1036-2008 Ukuzimisela kwe-coaring yokwandiswa kweplastiki ukusuka -30 ℃ ukuya kwi-30 ℃ ukuya kwi-30 ℃ indlela yokwandiswa kwemitha yokwandiswa kwe-quartz.
Ukuqhubela phambili kwe-thermal
Ukuqhutywa kwe-thermal (Ukusebenza kwe-thermal) kubhekiselelwe kwinqanaba lokuphuhliswa kobushushu kwindawo yeyunithi ephantsi kwendawo yokuhambisa ubushushu, i-Prependicular kwiZiko leZiko leZiko leZiko leZiko, ekwabizwa ngokuba kukulandelwa kwenqanaba leyunithi.
Ukuqhutywa kwe-thermal λ kubalwa yile fomula ilandelayo
Apho i-q isantya sokuqhutywa kwenqaku ngexesha rhoqo, j; Ubungqingqwa bobuqili, m; Inkangeleko yokudlulisela ubushushu obusebenzayo, m2; I-δz lixesha lokuphumla komlinganiso, I-δt ngumahluko wobushushu obuphakathi phakathi kweplate eshushu nebandayo, k.

3. Umthamo othile wobushushu
Umthamo othile wobushushu (umthamo othile wobushushu) ukwimeko echaziweyo, iyunithi yobushushu be-polymer yenyuke ngo-1
Umthamo othile wobushushu ubalwa ngokwefom yefomula elandelayo:
Apho i-δq bushushu obufuneke kwesamente, j; m bubunzima bomzekelo, kg; Δt ngumahluko kwiqondo lobushushu ngaphambi nasemva kokufumana ubushushu, k.

4. Iqondo lokushisa leglasi
I-Amorphous okanye i-Semi-Polymers, ukusuka kwi-Vicomers State Speed okanye i-Elastic ephezulu kwi-Glass State yeGlasi kubizwa ngokuba yinguqu yeglasi. Inguqu yeglasi yenzeka ngaphakathi koluhlu lobushushu obuncinci, iqondo lobushushu kwimigangatho yalo ebizwa ngokuba yi-Gload Transfied Translations (i-GLARE Transt).
Ubushushu benguqu yeglasi, indlela yokwanda esetyenziswayo esetyenziswayo okanye indlela yobushushu - indlela ye-cusforment - Ingasetyenziselwa nohlalutyo lwe-thermal olwahlukileyo, njenge-TDA, i-DSC, i-tma yokumiselwa.
Uvavanyo lwe-GB / T 11998-89 I-Treat yeTranslart yeTrans yeTekity yeThekhi yeDemple yendlela yokuhlaziya indlela yokufunda.
5. Ipropathi yoomatshini kubushushu obuphantsi
Iipropathi zoomatshini kwiqondo lobushushu elisezantsi (iipropathi zoomatshini kwiqondo lokushisa elisezantsi) limele indlela yokuziphatha yezinto eziphantsi. Iindlela eziqhelekileyo zovavanyo ezisetyenzisiweyo zisonge iqondo lobushushu eliphantsi, itampu kunye ne-elonghation kunye nezinye iindlela.
Iqondo lobushushu leBrittle Ngamandla athile uninzi lweflethi yesando, xa kunokwenzeka ukuba ama-50% amaqondo obushushu abizwa ngokuba yiBrittle ubushushu (℃).
Umgangatho wovavanyo: GB / T5470-2007 indlela yokuvavanya ubushushu.
6. Ukuchasana nobushushu bukaMar
I-Marten Lest (i-Marten's Lest ibhekisele kwiziko lokufudumeza, ukuze i-purimeny idluliselwe uxinzelelo oluthile, kwaye kwinqanaba elithile lobushushu, i-starimen ishushu kwisiphelo sesiphelo sexabiso le-SIRTE iqondo lobushushu (℃).

7. Inqaku le-Viccot
Ngaphantsi kwemeko yokufudumeza ngokulinganayo, i-therfler inomthwalo ochaziweyo kunye nendawo enqamlezileyo ye-LM2 ifakwe ngokuthe nkqo kwinqaku. Xa iflethi ibhobhoza i-therimeny l ubunzima beqondo lobushushu, oko kukuthi, izinto eziphathekayo ezilinganiselwe ngabaphunga beshushu (℃).
Umgangatho wovavanyo: GB / T 1633-2000 Ukuzimisela kweqondo lobushushu eVictat
8. Iqondo lokugcina i-thermal
Iqondo lokushisa le-thermal (i-thermal ye-thermal deoction) ibhekisa kubushushu (℃) apho i-macromolecules yezinto ezibonakalayo ziqhekezwe phantsi kwemeko yobushushu. Inokugqitywa yindlela elahlekileyo yobushushu, indlela eyahlukileyo yoxinzelelo lwendlela okanye indlela yokuchonga igesi yokufunyanwa (i-ta).
9. Ukuchasana neFlanga
Ukuxhathisa i-Flame kubhekisa kubuchule bokwenza izinto ukuze uxhathise ukudibana xa kunxibelelana nelangatye okanye ukuthintela ukudibanisa okuqhubekayo xa isuswe kwidangatye.
