Mochini oa ho etsa liteko tsa tensilee sebelisoa haholo tekong e tšesaane ea ho tsitsisa filimi, e sebelisoang haholo ho lekola thepa ea mochini le bokhoni ba deformation ea lisebelisoa tse tšesaane tsa filimi ts'ebetsong ea tsitsipano. Lintlha tse latelang ke tlhahlobo e qaqileng ea teko ea filimi ea "tensile" ea mochini oa liteko oa tensile:
1.Molao-motheo oa ho sebetsa
Mochini oa ho etsa liteko ka molaoli, sistimi ea taolo ea lebelo ho laola ho potoloha ha servo motor, e fokotsoang ke sistimi ea deceleration ka para e nepahetseng ea screw ho khanna beam holimo kapa tlase, e le ho fana ka tsitsipano ho sampole ea filimi. Nakong ea ts'ebetso ea tsitsipano, sensor ea mojaro e lekanya boleng ba ho ts'oara ka nako ea nnete, 'me phetoho ea matla a thata le bolelele ba sampole ea katoloso e tlalehiloe ke sistimi ea ho fumana data. Qetellong, ka software ea tlhahlobo ea data ho sebetsana le data e rekotiloeng, matla a tensile ea filimi, bolelele le matšoao a mang a ts'ebetso.
2.Mehato ea teko
Lokisetsa mohlala: Sebelisa sesebelisoa se khethehileng ho khaola sampuli e nang le mahlakore a mabeli ho tloha boitsebisong ba filimi ho finyella litlhoko, ho etsa bonnete ba hore boholo ba sampuli bo nepahetse le hore moeli ha o senyehe.
Qetella sampole: Beha lipheletso tse peli tsa sampole setulong sa mochini oa tlhahlobo ea tensile, 'me u lokise sebopeho ho netefatsa hore sampole e ts'oaroa ka thata le ho hokahana.
Beha litekanyetso tsa tlhahlobo: seta matla a ho jara esale pele, lebelo la ho tsitsa le liparamente tse ling ho latela litlhoko tsa tlhahlobo.
Qala ho otlolla: Qala mochini oa ho etsa liteko 'me butle-butle u sebelise tsitsipano e le hore sampole e atolohe ka lehlakoreng le thata.
Lintlha tsa ho rekota: Nakong ea ts'ebetso ea ho taka, phetoho ea matla a thata le bolelele ba mohlala oa katoloso e tlalehiloe ka nako ea nnete.
Ho robeha ha mohlala: Tsoela pele ho otlolla mohlala ho fihlela o robeha, rekota matla a mangata a matla le bolelele ba ho atolosoa ha khefu nakong ea ho robeha.
Tlhahlobo ea lintlha: Lintlha tse rekotiloeng lia sebetsoa le ho hlahlobisisoa ho fumana matla a tsitsipano, bolelele le matšoao a mang a ts'ebetso ea filimi.
3.Mekhoa e tloaelehileng ea teko
Teko ea longitudinal tensile: filimi e ka sehloohong ea teko ka lehlakoreng la longitudinal ea matla a thata, bolelele le matšoao a mang a ts'ebetso.
Teko ea "transverse tensile test": e ts'oana le teko ea longitudinal tensile, empa haholo-holo e leka mekhoa e tsitsitseng ea filimi ka lehlakoreng le ka holimo.
Teko ea meokho: leka matla a ho tabola le bolelele ba filimi, ka ho sebelisa tsitsipano ho etsa hore filimi e tabohe ka Angle e itseng.
Mekhoa e meng ea liteko: joalo ka tlhahlobo ea phello, tlhahlobo ea coefficient ea khohlano, joalo-joalo, mekhoa e nepahetseng ea tlhahlobo e ka khethoa ho latela litlhoko tse ikhethileng.
4. Sebaka sa kopo
Teko ea mochini oa ho etsa liteko tsa "tensile" e sebelisoa haholo ho terata le thapo, lisebelisoa tsa moaho, sefofane, tlhahiso ea metjhini, polasetiki ea rabara, masela, lisebelisoa tsa lapeng le liindasteri tse ling tsa tlhahlobo le tlhahlobo ea thepa. Ka nako e ts'oanang, hape ke lisebelisoa tse loketseng tsa tlhahlobo bakeng sa litsi tsa lipatlisiso tsa mahlale, likoleche le liunivesithi, likhoebo tsa indasteri le tsa merafo, taolo ea botekgeniki, phehisano ea tlhahlobo ea thepa le mafapha a mang.
5. Litekanyetso tsa liteko
Mochini oa ho etsa liteko tsa filimi tekong ea ho ts'oaroa ha filimi, o lokela ho latela litekanyetso tse amehang tsa naha le tsa machabeng, joalo ka GB/T 1040.3-2006 "thepa ea polasetiki e tiileng ea qeto ea Karolo ea 3: maemo a teko ea filimi le oafer" joalo-joalo. Litekanyetso tsena li hlakisa litlhoko tsa maemo a tlhahlobo, tokiso ea sampole, mehato ea liteko, ts'ebetso ea data, joalo-joalo, ho netefatsa bonnete le ts'epahalo ea liphetho tsa liteko.
