Txawm hais tias cov yas muaj ntau yam zoo, tsis yog txhua hom yas muaj txhua yam zoo. Cov kws ua haujlwm khoom siv thiab cov neeg tsim qauv kev lag luam yuav tsum nkag siab txog cov yam ntxwv ntawm ntau yam yas kom tsim tau cov khoom yas zoo meej. Cov yam ntxwv ntawm yas, tuaj yeem muab faib ua cov yam ntxwv lub cev yooj yim, cov yam ntxwv kho tshuab, cov yam ntxwv thermal, cov yam ntxwv tshuaj lom neeg, cov yam ntxwv kho qhov muag thiab cov yam ntxwv hluav taws xob, thiab lwm yam. Cov yas engineering yog hais txog cov yas siv rau kev lag luam siv ua cov khoom lag luam lossis cov khoom siv plhaub. Lawv yog cov yas uas muaj zog zoo heev, tiv taus kev cuam tshuam, tiv taus cua sov, tawv thiab tiv thaiv kev laus. Kev lag luam Nyij Pooj yuav txhais nws tias "siv tau ua cov khoom siv thiab cov khoom siv kho tshuab ntawm cov yas ua tau zoo, tiv taus cua sov siab dua 100 ℃, feem ntau siv hauv kev lag luam".
Hauv qab no peb yuav teev qee cov feem ntau sivcov cuab yeej kuaj:
1.Cov Ntsuas Kev Nqus Dej Yaj(MFI):
Siv rau kev ntsuas qhov ntsuas ntawm qhov ntsuas ntawm cov yas thiab cov resins uas muaj viscous flow state MFR. Nws yog qhov tsim nyog rau cov yas engineering xws li polycarbonate, polyarylsulfone, fluorine plastics, nylon thiab lwm yam uas muaj qhov kub siab melting. Kuj tseem siv tau rau polyethylene (PE), polystyrene (PS), polypropylene (PP), ABS resin, polyformaldehyde (POM), polycarbonate (PC) resin thiab lwm yam yas uas qhov kub qis melting. Ua tau raws li cov qauv: ISO 1133, ASTM D1238, GB/T3682
Txoj kev sim yog cia cov yas yaj rau hauv cov kua yas hauv ib lub sijhawm (10 feeb), nyob rau hauv qee qhov kub thiab siab (cov qauv sib txawv rau ntau yam khoom siv), thiab tom qab ntawd ntws tawm los ntawm 2.095mm txoj kab uas hla ntawm tus lej ntawm grams (g). Qhov ntau dua tus nqi, qhov zoo dua qhov ua kua ntawm cov khoom siv yas, thiab vice versa. Tus qauv sim feem ntau siv yog ASTM D 1238. Lub cuab yeej ntsuas rau tus qauv sim no yog Melt Indexer. Cov txheej txheem ua haujlwm tshwj xeeb ntawm kev sim yog: cov khoom polymer (yas) uas yuav tsum tau sim yog muab tso rau hauv ib lub qhov me me, thiab qhov kawg ntawm lub qhov txuas nrog lub raj nyias, lub txoj kab uas hla ntawm uas yog 2.095mm, thiab qhov ntev ntawm lub raj yog 8mm. Tom qab cua sov mus rau qee qhov kub, qhov kawg sab saud ntawm cov khoom siv raw raug nias rau hauv qab los ntawm qee qhov hnyav siv los ntawm lub piston, thiab qhov hnyav ntawm cov khoom siv raw raug ntsuas hauv 10 feeb, uas yog qhov ntsuas ntws ntawm cov yas. Qee zaum koj yuav pom tus sawv cev MI25g/10 feeb, uas txhais tau tias 25 grams ntawm cov yas tau raug extruded hauv 10 feeb. Tus nqi MI ntawm cov yas siv feem ntau yog ntawm 1 thiab 25. Qhov loj dua MI, qhov me dua qhov viscosity ntawm cov khoom siv yas raw thiab qhov me dua qhov hnyav molecular; txwv tsis pub, qhov loj dua qhov viscosity ntawm cov yas thiab qhov loj dua qhov hnyav molecular.
2. Tshuab Ntsuas Kev Sib Tw Thoob Ntiaj Teb (UTM)
Tshuab kuaj khoom siv thoob ntiaj teb (tshuab tensile): sim cov khoom tensile, tearing, bending thiab lwm yam khoom siv kho tshuab ntawm cov khoom yas.
Nws muaj peev xwm muab faib ua pawg hauv qab no:
1)Lub zog tensile&Kev ntev:
Lub zog tensile, tseem hu ua lub zog tensile, hais txog qhov loj ntawm lub zog uas xav tau los ncab cov khoom yas mus rau qee qhov, feem ntau qhia txog ntau npaum li cas lub zog ib chav tsev, thiab feem pua ntawm qhov ntev ncab yog qhov ntev. Lub zog tensile Lub zog tensile ntawm cov qauv feem ntau yog 5.0 ~ 6.5mm / feeb. Txoj kev xeem ntxaws ntxaws raws li ASTM D638.
2)Lub zog flexual&Lub zog khoov:
Lub zog khoov, tseem hu ua lub zog khoov, feem ntau yog siv los txiav txim siab qhov kev tiv thaiv khoov ntawm cov yas. Nws tuaj yeem kuaj tau raws li ASTMD790 txoj kev thiab feem ntau yog qhia txog ntau npaum li cas lub zog ib cheeb tsam. Cov yas dav dav rau PVC, Melamine resin, epoxy resin thiab polyester lub zog khoov yog qhov zoo tshaj plaws. Fiberglass kuj tseem siv los txhim kho qhov kev tiv thaiv khoov ntawm cov yas. Kev khoov elasticity txhais tau tias kev ntxhov siab khoov tsim ib chav ntawm deformation hauv qhov ntau elastic thaum cov qauv khoov (txoj kev sim xws li lub zog khoov). Feem ntau, qhov ntau dua qhov elasticity khoov, qhov zoo dua qhov rigidity ntawm cov khoom yas.
3)Lub zog compressive:
Lub zog nias yog hais txog lub peev xwm ntawm cov yas kom tiv taus lub zog nias sab nraud. Tus nqi xeem tuaj yeem txiav txim siab raws li txoj kev ASTMD695. Polyacetal, polyester, acrylic, urethral resins thiab meramin resins muaj cov khoom zoo heev hauv qhov no.
3.Tshuab kuaj kev cuam tshuam ntawm cantilever/ Stshuab kuaj kev cuam tshuam ntawm lub nqaj hlau uas txhawb nqa tsis pom tseeb
Siv rau kev sim qhov cuam tshuam ntawm cov khoom siv tsis yog hlau xws li daim ntawv yas tawv, yeeb nkab, cov khoom siv zoo li tus kheej, nylon txhawb nqa, iav fiber txhawb nqa yas, ceramic, pob zeb pov tseg hluav taws xob rwb thaiv tsev, thiab lwm yam.
Ua raws li tus qauv thoob ntiaj teb ISO180-1992 "kev txiav txim siab txog lub zog ntawm cov yas - cov khoom siv tawv cantilever"; Tus qauv hauv tebchaws GB / T1843-1996 "txoj kev sim tshuaj ntsuam kev cuam tshuam ntawm cov yas tawv cantilever", tus qauv kev lag luam tshuab JB / T8761-1998 "tshuab kuaj tshuaj ntsuam kev cuam tshuam ntawm cov yas cantilever".
