Li-Index tsa Ts'ebetso ea 6 Bakeng sa ho Fumana Boleng ba Lisebelisoa tsa ho Tiisa

1. Ts'ebetso ea Tensile

Thepa ea tensile ke thepa ea bohlokoa ka ho fetisisa ea thepa ea ho tiisa, ho kenyelletsa matla a ho tiea, khatello ea maikutlo e sa feleng, bolelele nakong ea khefu le deformation e sa feleng nakong ea khefu.Matla a tsitsitseng ke khatello e phahameng ka ho fetisisa eo mohlala o otlolohileng ho eona ho robeha.Khatello e sa feleng ea elongation (modulus of elongation e sa feleng) ke khatello e fihlelletsoeng ka bolelele bo boletsoeng.Elongation ke ho fetoha ha mohlala ho bakoang ke matla a itseng a thata.Ho sebelisoa karo-karolelano ea elongation increment ho bolelele ba pele.Bolelele nakong ea khefu ke bolelele ba khefu ea mohlala.The tensile permanent deformation ke mesaletsa ea deformation pakeng tsa mela e tšoaeang ka mor'a ho robeha ha tsitsipano.

2. Ho thatafala

Ho thatafala ha thepa ea ho tiisa ho hanyetsa khatello ea kantle ho bokhoni, empa hape le e 'ngoe ea ts'ebetso ea mantlha ea thepa ea ho tiisa.Ho thatafala ha thepa ho amana le thepa e 'ngoe ho isa bohōleng bo itseng.Ha boima bo phahame, matla a maholo, ho fokotseha ho tlase, ho hanyetsa ho apara ho molemo le ho feta ho hanyetsa mocheso o tlaase.

3. Compressibility

Ka lebaka la viscoelasticity ea thepa ea rabara, khatello e tla fokotseha ha nako e ntse e tsamaea, e leng se bontšang ho phomola ha khatello ea kelello, 'me e ke ke ea khutlela sebopeho sa pele ka mor'a ho tlosa khatello, e leng se bontšang e le compression deformation e sa feleng.Sebakeng sa mocheso o phahameng le oli ea oli ketsahalo ena e totobetse haholoanyane, ts'ebetso ena e amana ka ho toba le ho tšoarella ha lihlahisoa tsa ho tiisa.

6. Ho Hanyetsa botsofali

Lisebelisoa tsa ho tiisa ka oksijene, ozone, mocheso, leseli, metsi, khatello ea mechine e tla lebisa ho senyeha ha ts'ebetso, e tsejoang e le botsofali ba thepa ea ho tiisa.Botsofali Resistance (eo hape e tsejoang e le ho hanyetsa boemo ba leholimo) e ka sebelisoa ka mor'a mokhoa oa ho tsofala oa matla, bolelele, liphetoho tse thata ho bontša hore tekanyo ea phetoho e nyenyane, e molemo ho hanyetsa botsofali.

Tlhokomeliso: boemo ba leholimo bo bolela letoto la liketsahalo tsa botsofali, tse kang ho fela, ho fetoha ha mebala, ho phunyeha, phofo le ho fokotsa matla a lihlahisoa tsa polasetiki ka lebaka la tšusumetso ea maemo a ka ntle a kang ho pepeseha ha letsatsi, phetoho ea mocheso, moea le pula.Mahlaseli a ultraviolet ke e 'ngoe ea lintlha tse ka sehloohong tse khothalletsang botsofali ba polasetiki.
