Txawm hais tias DASTSICS muaj ntau yam khoom zoo, tsis yog txhua hom plastics tuaj yeem muaj txhua yam zoo. Cov ntaub ntawv Engineers thiab cov tsim qauv tsim qauv yuav tsum nkag siab cov khoom ntawm ntau yam plastics nyob rau hauv thiaj li tsim cov khoom yas zoo meej. The property of plastic, can be divided into basic physical property, mechanical property, thermal property, chemical property, optical property and electric property, etc. Engineering plastics refer to industrial plastics used as industrial parts or shell materials. Lawv yog cov plastics nrog lub zog zoo, cuam tshuam tsis kam, kub kuj, lub zog tiv thaiv kev laus. Kev lag luam Japanese yuav txhais tau nws li "tuaj yeem siv ua cov txheej txheem thiab cov tshuab hluav taws xob ntawm cov huab cua siab, kub ua rau sab saud 100 ℃, tsuas yog siv hauv kev lag luam".
Hauv qab no peb yuav sau qee cov siv feem ntauKuaj cov twj:
1.Qhuav ntawm kev ntsuas ntsuas(MFI):
Siv rau kev ntsuas tus nqi txaus MFR MFR tus nqi ntawm ntau yam plastics thiab resins nyob rau hauv lub xeev plees. Nws yog tsim nyog rau kev tsim cov plastics xws li Polycarbonate, polyarylsulfone, fluorine plastics, nylon thiab yog li ntawm kev kub yaj. Kuj tsim nyog rau polyethylene (PE), pérenyrene (POM), Polycarbonate (PC) Resin thiab lwm yam yas melting kub yog qhov ntsuas qis. Raws li cov qauv: ISO 1133, ASTM D1238, GB / T3682
Cov qauv kev xeem yog kom cia cov yas ua kua yaj rau hauv cov kua roj hmab tsis pub dhau cov ntaub ntawv (10 feeb), thiab tom qab ntawd cov txheej txheem sib txawv ntawm tus lej ntawm cov neeg (g). Cov txiaj ntsig zoo dua tus nqi, qhov zoo dua kev ua tiav ntawm cov khoom siv yas, thiab hloov ua lwm yam. Cov txheej txheem ntsuas feem ntau yog ASTM D 1238. Kev ntsuas ntsuas rau tus qauv ntsuas no yog MELT INDORDER. Cov txheej txheem kev ua haujlwm tshwj xeeb ntawm kev xeem yog: cov khoom siv yas (yas) Lub raj yog 8 hli. Tom qab muab cua sov rau qhov ntsuas kub thiab txias, lub siab ntawm cov khoom siv raw yog ntsuas ntawm cov khoom siv hnyav, thiab qhov hnyav tsis pub dhau 10 feeb, uas yog qhov kev txaus siab ntawm cov yas. Qee zaum koj yuav pom cov sawv cev Mi25G / 10min, uas txhais tau tias 25 grams ntawm cov yas tau extruded hauv 10 feeb. MI tus nqi ntawm cov kev siv yas feem ntau yog nruab nrab ntawm 1 thiab 25. Qhov loj dua ntawm cov khoom siv yas ntawm cov khoom siv yas thiab qhov me me; Txwv tsis pub, qhov loj dua lub viscosity ntawm cov yas thiab cov loj dua cov molecular hnyav.
2.Universal Tensile Kuaj Tshuab (UTM)
Universal Khoom Kuaj Tshuab (Tensile Tshuab): Kev tshuaj ntsuam lub tensile, kua muag, khoov thiab lwm yam khoom siv ntawm cov ntaub ntawv yas.
Nws tuaj yeem faib ua cov hauv qab no:
1)Lub zog tensile&Elongation:
Lub zog tensile, tseem hu ua lub zog tensile, yog hais txog qhov loj me uas yuav tsum tau ua rau ncab uas yuav tsum muaj qee qhov, thiab feem pua ntawm cov ncab ntev yog elongation. Tensile zog lub tensile ceev ntawm cov quav me yog feem ntau 5.0 ~ 6.0 / min. Cov ncauj lus kom ntxaws raws li ASTM D638.
2)Lub zog&Dab tsi yog khoov zog:
Dab tsi yog khoov zog, tseem hu ua qhov muaj zog yooj yim, feem ntau yog siv los txiav txim siab ntawm FLEXURAL RESISTANCE YAFASTICS. Nws tuaj yeem raug sim ua raws li Astmd790 Txujci thiab feem ntau qhia tawm hauv cov nqe lus ntawm ntau npaum li cas quab yuam ib cheeb tsam. General plastics rau PVC, Melamine Resin, Epoxy Resin thiab Polyester khoov rau lub zog yog qhov zoo tshaj plaws. Cov fiberglass kuj tseem siv los txhim kho cov folding ua kom tsis pom kev ntawm plastics. Dabtsi yog khoov elasticity hais txog qhov kev ntxhov siab rau ib tus nqi ntawm deformation nyob rau hauv elasticity nyob rau hauv elasticity nyob rau hauv elasticity muaj ntau thaum cov me me yog khoov (cov qauv xeem xws li khoov zog). Feem ntau, qhov ntau dua cov dab tsi yog khoov elasticity, qhov zoo dua ntawm cov khoom siv yas.
3)Compressive lub zog:
Lub zog compression lub zog yog hais txog lub peev xwm ntawm plastics kom tiv taus sab nraud compression zog. Tus nqi xeem yuav raug txiav txim siab raws li ASTMD695 txoj kev. Polyacetal, polyester, acrylic, urethal resins thiab cov hmoov muaj hmoov muaj cov khoom muaj txiaj ntsig zoo hauv txoj kev hwm no.
3.CANTILDER cuam tshuam tshuab/ Simprupted nqaj cuam tshuam kev kuaj tshuab
Siv rau kev sim cov kev cuam tshuam nyuaj ntawm cov ntaub ntawv me me xws li cov ntaub ntawv yas tawv, cov raj mis, pov cov pob zeb, pov cov pob zeb hluav taws xob insulating, thiab lwm yam
Nyob rau hauv kab nrog tus qauv thoob ntiaj teb ISO180-1992 "Yas - Cov Khoom Siv Tsis Muaj Zog - Cantilever cuam tshuam lub zog kev txiav txim siab"; Tus Qauv Lub Tebchaws GB / T1843-1996 "Cantilever cuam tshuam cuam tshuam cuam tshuam", kev lag luam kev lag luam JB / T8761-1998 "Cov Cantilever cuam tshuam cuam tshuam dab".
4.Qhov kev sim siab: Simulating cov huab cua tsis kam ntawm cov ntaub ntawv.
1) Qhov ntsuas kub tsis tu ncua, cov cua sov tas li yog ntsuas hluav taws xob xws li cov khoom siv hluav taws xob, kev ntsuas hluav taws xob, tsim nyog rau kev lag luam seem, Qhov chaw, Semi-tiav cov khoom lag luam, hluav taws xob, hluav taws xob, seem rau qhov kub thiab txias, ntsuas kub thiab av noo ib puag ncig.
2) Precision Laus xeem lub thawv, UV Laus Test Test Box (Ultraviolet Lub Teeb), Muaj Ntau Thiab Kub Kub Kuaj Lub thawv,
3) SAUNAMMED THERMAL SHOCK SEARER
4) Kev ntsuas kub thiab kub cuam tshuam hluav taws xob yog hluav taws xob thiab kev tshawb xyuas hluav taws xob, kev tshawb fawb kev tshawb fawb, nws haum rau kev hloov pauv ntawm lub cev seem thiab cov ntaub ntawv ntawm lwm cov khoom xws li photicelectric, cov khoom lag luam hluav taws xob, ntsuas hluav taws xob ntsig txog cov khoom lag luam uas cua sov thiab cov cua txias Cov.
5) Muaj Siab Thiab Kub Thiab Kub Hloov Kev Ntsuas Chamber
6) Xenon-teeb Txheej Xwm Tiv Thaiv Chamber
7) HDT Vicat Tester
