Mokhoa oa ho lemoha morero oa mochini oa teko oa tensile

1. Mekhoa ea teko ea matla a tsitsipano le bolelele nakong ea khefu
Tekanyetso ea boleng: GB13022-91 "Mokhoa oa liteko bakeng sa thepa e tsitsitseng ea lifilimi tsa polasetiki"

Mofuta oa mohlala: Mefuta ea I, II, le III ke li-dumbbells, 'me Mofuta oa IV ke oa mohala o molelele.Mefuta ea mofuta oa IV ke mofuta o tloaelehileng.

Tokiso ea mohlala: bophara ke 15mm, bolelele ba sampuli ha bo ka tlase ho 150mm, 'me bolelele ba gauge bo tiisitsoe ho ba 100mm.Bakeng sa disampole tse nang le sekhahla se seholo sa deformation ea thepa, bolelele ba gauge ha boa lokela ho ba tlase ho 50mm.

Lebelo la teko: 500±30mm / min

Litaba tse hlokang ho hlokomeloa: Mohlala o behiloe ka har'a li-clamp tse peli tsa mochini oa tlhahlobo, e le hore axis ea longitudinal ea sampole e tsamaellane le mohala o bohareng oa li-clamp tse ka holimo le tse tlase, 'me li-clamps li tiee hantle.

2. Mokhoa oa teko oa ho fumana matla a tiiso ea mocheso

Tekanyetso ea boleng: QB/T2358-98 Mokhoa oa teko oa matla a ho tiisa mocheso oa liphutheloana tsa filimi ea polasetiki.

Mehato ea liteko: nka karolo ea ho tiisa mocheso e le setsi, e bule likhato tse 180, koala lipheletsong tse peli tsa sampole ho lisebelisoa tse peli tsa mochini oa tlhahlobo, axis ea sampole e lokela ho tsamaellana le mohala o bohareng oa lisebelisoa tse holimo le tse tlase. , 'me ho tiisa ho lokela ho ba ho loketseng.Sebaka se pakeng tsa li-clamps ke 100mm, 'me li huloa ka lebelo le itseng ho bala mojaro ha sampuli e robeha.Haeba sampole e robehile, sampole ha e sebetse.

3. Mokhoa oa teko bakeng sa 180 ° ho fumana matla a lekhapetla

Tekanyetso ea boleng: sheba mokhoa oa tlhahlobo oa tlhahlobo ea lisebelisoa tsa polasetiki tse nang le motsoako o bonolo oa GB8808.

Tokiso ea mohlala: bophara ke 15mm (ho kheloha ha hoa lokela ho feta 0.1mm), bolelele ke 200mm;pele ho peel 50mm hammoho le tataiso ea bolelele, 'me ho ke ke ha e-ba le tšenyo e totobetseng karolong ea pele e ebotsoeng.

Haeba sampole e se bonolo ho ebola, ntlha e le 'ngoe ea sampole e ka qoelisoa ka har'a mokelikeli (o atisang ho sebelisoa ka ethyl acetate le acetone) hoo e ka bang 20mm.

Ts'ebetso ea liphetho tsa liteko: Bala ka karolelano matla a peel ka ho nka mokhoa oa ho nka litekanyetso tse ts'oanang.Karolo ea teko ke N/15MM.

Tlhokomeliso: Ha lera le kopantsoeng le ke ke la ebolloa kapa lera le kopantsoeng le robehile, matla a lona a lekhapetla a nkoa e le a tšoanelehang, empa matla a tsitsitseng a tlameha ho netefatsoa hore a tšoanelehe.
