Thermal expansion thiab contraction yuav tsum yog cov nyhuv ntawm qhov kub thiab txias ntawm tag nrho cov phab ntsa.Kub ncaj qha cuam tshuam rau shrinkage, tshwj xeeb tshaj yog rau cov tawv PVC nrog shrinkage.Lub shrinkage ntawm molded PVC yog hais txog 0.1-0.5%, thiab thermal expansion thiab contraction kub yog 70 ° C.Hauv lwm lo lus, saum toj no peb txhiab yog raws li qhov no.
Txawm li cas los xij, peb yuav tsis quav ntsej tias cov phab ntsa sib xyaw ua ke yog ib hom tshiab ntawm cov khoom sib xyaw nrog ntau cov ntaub ntawv sib txawv, xws li xyoob hmoov, ntoo fiber ntau thiab calcium hmoov, ntxiv rau kev pab tsim nyog thiab kub nias.Yog tias cov khoom siv raw yuav tsum sib xyaw ua ke, lawv yuav tsum tiv taus qhov kub thiab txias.Raws li kev tshawb fawb, qhov kub thiab txias thaum lub sijhawm nias tuaj yeem ncav cuag 130 degrees.Cov ntaub ntawv ntsig txog: Lub thermal expansion thiab contraction kub ntawm PVC yog 70 ° C, tab sis sab hauv tsev kub feem ntau yog ib qho nyuaj rau siab tshaj 45 degrees, thiab nws yog ib qho nyuaj rau ncav cuag qhov kub ntawm thermal expansion thiab contraction.Nws tuaj yeem hais tias peb yuav tsum tsis txhob txhawj.
Tsis tas li ntawd, tus nqi ntawm calcium hmoov thiab ntoo hmoov nyob rau hauv cov phab ntsa integrated kuj yog ib qho tseem ceeb uas cuam tshuam rau kev ua tau zoo ntawm cov phab ntsa integrated.Ntxiv nrog rau kev txhim kho kev ua tau zoo ntawm phab ntsa monolithic los ntawm kev tsim qauv, cov qauv thickened lossis porous hollow tam sim no siv nyob rau hauv cov phab ntsa monolithic nws tus kheej kuj yog ib txoj kev los tiv thaiv kev nthuav dav.
Kev ua tau zoo ntawm cov khoom yuav tsum raug xam tias yog tag nrho, tsis yog los ntawm kev ua haujlwm ntawm qee yam khoom siv raw.Yog li ntawd, peb yuav tsum kho qee qhov hu ua pov thawj hais lus kom raug.Tam sim no, kev lag luam phab ntsa sib xyaw ua ke tau maj mam txais los ntawm cov pej xeem.Tau kawg, ntau tus phooj ywg yuav tawm tsam nws hauv lwm txoj kev.Tsuav nws muaj tseeb, nws yuav raug daws.
