Hydrostatic test method: Txoj kev ntsuas hydrostatic rau cov kav dej yas hauv cov dej txuag dej feem ntau yog coj mus kuaj cov kav dej yas hauv lub sijhawm teev nyob rau hauv lub xeev hydrostatic tas li. Nyob rau hauv tus txheej txheem ntawm sampling, yuav tsum nruj me ntsis raws li cov kev cai nyob rau hauv lub "Internal Pressure Resistance Test Method of Thermoplastic Plastic Pipes for Fluid Transport" uas tau tshaj tawm los ntawm cov koom haum cuam tshuam ntawm peb lub teb chaws. Ua ntej, cov qauv kuaj cov yeeb nkab uas muaj dej yuav tsum tau muab tso rau hauv qhov kev sim. Nyob rau hauv lub tank dej, qhov kub thiab txias ntawm lub tank dej yog hloov raws li qhov kev sim cov yeeb nkab kuaj hauv qhov kev sim. Nyob rau hauv cov txheej txheem ntawm kev sim, nws yog ib qho tsim nyog yuav tsum tau faib cov nruab nrab hauv cov yeeb nkab hydrostatic sim rau hauv dej, huab cua lossis lwm yam kua raws li kev sim ntsuas ntawm hydrostatic siab. Nyob rau tib lub sijhawm, thaum lub sijhawm sim hydrostatic ntawm cov kav dej yas, nws yog ib qho tsim nyog yuav tsum tau sau cov kev sim tshwj xeeb ntawm cov yeeb nkab hauv kev sim. Tom qab cov yeeb nkab yuav tsum tau sim mus txog lub sij hawm teem rau kev sim, tus neeg sim yuav tsum tau soj ntsuam seb cov yeeb nkab nyob rau hauv kev sim puas puas los ntawm hydrostatic siab. Kuv pom tias cov yeeb nkab hauv kev sim tau tawg lossis tawg ntau dhau thaum lub sijhawm sim, yog li tus kws sim yuav tsum txheeb xyuas cov laj thawj tshwj xeeb rau kev puas tsuaj ntawm cov yeeb nkab.
Elongation ntawm kev ntsuas kev tawg: Txoj kev sim rau elongation ntawm kev tawg ntawm cov kav dej yas hauv cov dej txuag dej yog feem ntau los xyuas cov khoom ntawm cov kav dej yas thiab cov khoom siv. Nyob rau hauv tus txheej txheem ntawm kev ntsuam xyuas lub elongation ntawm so, tus neeg sim yuav tsum nruj me ntsis raws li qhov yuav tsum tau muaj nyob rau hauv "Kev txiav txim ntawm Tensile Properties ntawm Thermoplastic Pipes" tshaj tawm los ntawm cov koom haum muaj feem ntawm peb lub teb chaws. Thaum lub sij hawm kev xeem txheej txheem, qhov ntsuas kub yuav tsum tau khaws cia nyob nruab nrab ntawm 20 degree thiab 23 degree, cov yeeb nkab nyob rau hauv kev sim yuav tsum tau muab tso rau hauv lub tshuab sim rau tensile thwmsim ntawm txawv tus nqi, thiab raws li cov kev sim, yuav tsum tau. txheeb xyuas seb txhua cov yeeb nkab yas haum puas raug puas ntsoog thaum lub sij hawm kuaj pob txha tensile. Qhov laj thawj tshwj xeeb yog vim li no, peb tuaj yeem muaj kev nkag siab meej txog lub zog tensile ntawm cov kav dej yas hauv cov txheej txheem ntawm kev txuag dej, thiaj li ua kom muaj kev nyab xeeb ntawm kev txuag dej kev tsim kho. Vicat thermal deformation nrhiav kom tau txoj kev: Nyob rau hauv cov txheej txheem ntawm Vicat thermal deformation nrhiav kom tau cov yas kav hauv cov dej txuag dej, nws yog qhov tseem ceeb los xyuas qhov kub ntawm cov kav dej yas hauv cov txheej txheem thov. Cov qib hauv kev ua haujlwm kub ua haujlwm tau muab faib kom raug. Nyob rau hauv tus txheej txheem ntawm Vicat thermal deformation nrhiav kom tau, cov neeg soj ntsuam yuav tsum nruj me ntsis raws li qhov yuav tsum tau ntawm "Kev txiav txim ntawm Vicat Softening kub ntawm Thermoplastic Pipes thiab Fittings" tshaj tawm los ntawm cov koom haum muaj feem hauv kuv lub teb chaws. Thaum lub sij hawm kev sim Vicat kub deformation, yog tias qhov kub ntawm cov yeeb nkab tuaj yeem ncav cuag thaum lub sij hawm sim siab dua, nws txhais tau tias cov thermal stabilization nyhuv ntawm cov yeeb nkab yas haum zoo dua. Ntawm qhov tsis sib xws, nws txhais tau hais tias cov thermal stabilization nyhuv ntawm cov yas yeeb nkab haum tsis zoo.
