Hav nyob ntawd! Raws li ib tug neeg muag khoom ntawm PVC jumbo hnab, kuv feem ntau tau nug txog ntau yam kev qhia ntawm cov khoom no. Ib lo lus nug uas tshwm sim ntau zaus yog, "Dab tsi yog qhov elongation ntawm kev tawg ntawm PVC jumbo hnab?" Hauv tsab ntawv blog no, kuv yuav rhuav nws rau koj thiab piav qhia vim li cas nws yog qhov tseem ceeb.
Elongation ntawm Break yog dab tsi?
Cia peb pib nrog cov hauv paus. Elongation ntawm so yog ib qho kev ntsuas ntawm ntau npaum li cas cov khoom tuaj yeem ncav cuag ua ntej nws thaum kawg tawg. Nws yog feem ntau qhia raws li feem pua. Piv txwv li, yog tias lub hnab PVC jumbo muaj qhov elongation ntawm kev tawg ntawm 200%, nws txhais tau tias nws tuaj yeem ncav cuag ob zaug nws qhov ntev ntev ua ntej snapping.
Cov cuab yeej no tseem ceeb heev vim nws muab peb lub tswv yim ntawm cov khoom siv tawv thiab hloov tau npaum li cas. Nyob rau hauv cov ntaub ntawv ntawm PVC jumbo hnab, ib tug ntau elongation ntawm so feem ntau txhais tau hais tias lub hnab muaj peev xwm tiv taus ntau zog thiab strain yam tsis muaj tearing. Qhov no yog qhov tseem ceeb heev, tshwj xeeb tshaj yog thaum cov hnab siv los nqa cov khoom hnyav lossis hnyav.
Vim li cas Elongation ntawm Break Matter rau PVC Jumbo Hnab?
Tam sim no, tej zaum koj yuav xav tsis thoob vim li cas qhov no yog qhov loj rau PVC jumbo hnab. Zoo, muaj ob peb yam.
Durability
Ua ntej tshaj, durability yog qhov tseem ceeb. Thaum koj siv cov hnab no los thauj khoom, koj xav kom lawv kav ntev. Ib lub hnab nrog lub siab elongation thaum so tsis tshua muaj kev sib tsoo los yog tsim kua muag thaum tuav, thauj khoom, thiab tshem tawm. Qhov no txhais tau tias tsawg dua lub hnab puas thiab cov khoom poob tsawg, uas yog qhov yeej rau txhua tus.
Yooj yim
PVC jumbo hnab yuav tsum tau hloov pauv kom haum raws li cov duab ntawm cov khoom. Txawm hais tias koj tab tom ntim khoom tsis tu ncua lossis ntim lub hnab kom nws lub peev xwm siab tshaj plaws, lub hnab yuav tsum tau ncab thiab yoog raws. Ib qho zoo elongation ntawm so kom paub meej tias lub hnab tuaj yeem ua li ntawd yam tsis muaj kev tawg.
Kev nyab xeeb
Kev nyab xeeb kuj yog ib qho kev txhawj xeeb loj. Yog tias lub hnab tawg thaum thauj, nws tuaj yeem ua rau muaj kev raug mob hnyav rau cov neeg ua haujlwm thiab kev puas tsuaj rau ib puag ncig ib puag ncig. Los ntawm kev xaiv PVC jumbo hnab nrog lub siab elongation thaum so, koj yuav txo tau qhov kev pheej hmoo ntawm kev sib tsoo thiab ua kom muaj kev nyab xeeb ntawm kev ua haujlwm.
Cov yam ntxwv cuam tshuam rau elongation thaum tawg
Muaj ntau ntau yam uas tuaj yeem cuam tshuam qhov elongation ntawm kev tawg ntawm PVC jumbo hnab. Cia peb saib qee qhov tseem ceeb tshaj plaws.
PVC Zoo
Qhov zoo ntawm PVC siv los ua cov hnab yog qhov tseem ceeb. Siab dua - zoo PVC feem ntau muaj cov khoom siv kho tshuab zoo dua, suav nrog kev elongation ntau dua thaum so. Ntawm peb lub tuam txhab, peb tsuas yog siv sab saum toj - qib PVC kom ntseeg tau tias peb lub hnab ua tau raws li cov qauv siab tshaj plaws.
Kev tsim khoom
Txoj kev uas lub hnab raug tsim los kuj ua lub luag haujlwm. Cov txheej txheem extrusion thiab vuam zoo tuaj yeem pab txhim kho qhov elongation ntawm lub hnab tawg. Peb siv lub xeev- ntawm-- cov txheej txheem tsim khoom los xyuas kom meej tias peb lub hnab muaj zog thiab ruaj khov.
Cov tshuaj ntxiv
Cov khoom siv ntxiv tuaj yeem siv los txhim kho cov khoom ntawm PVC. Piv txwv li, plasticizers tuaj yeem ua rau kom yooj yim ntawm cov khoom siv, uas tuaj yeem ua rau kom muaj qhov ntev dua thaum so. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum tau siv cov tshuaj ntxiv kom tsis txhob cuam tshuam lwm yam khoom ntawm lub hnab.
Kuaj Elongation ntawm Break
Yog li, yuav ua li cas peb ntsuas qhov elongation ntawm kev tawg ntawm PVC jumbo hnab? Zoo, muaj cov qauv kev sim uas peb ua raws. Ib txoj hauv kev zoo tshaj plaws yog kev sim tensile.
Hauv kev sim tensile, ib qho piv txwv ntawm cov khoom siv PVC yog clamped ntawm ob qho kawg thiab rub kom txog thaum nws tawg. Lub tshuab ntsuas qhov quab yuam siv thiab tus nqi ntawm stretch. Lub elongation ntawm kev so yog ces xam raws li qhov feem pua nce nyob rau hauv ntev piv rau qhov ntev ntev.
Ntawm peb lub tuam txhab, peb ua cov kev ntsuam xyuas tsis tu ncua los xyuas kom meej tias peb cov hnab PVC jumbo ua tau raws li qhov teev tseg elongation ntawm qhov yuav tsum tau ua. Peb kuj muab cov ntawv xeem rau peb cov neeg siv khoom kom lawv muaj kev thaj yeeb nyab xeeb.
Tiag -Kev Siv Ntiaj Teb
Tam sim no peb nkag siab tias qhov elongation ntawm kev so yog dab tsi thiab vim li cas nws tseem ceeb, cia peb saib qee qhov tiag -cov ntawv thov hauv ntiaj teb ntawm PVC jumbo hnab.
Ua liaj ua teb
Hauv kev lag luam ua liaj ua teb, PVC jumbo hnab yog siv los thauj thiab khaws cov nplej, noob, chiv, thiab lwm yam khoom ua liaj ua teb. Cov hnab no yuav tsum muaj zog txaus los tiv thaiv qhov hnyav ntawm cov khoom thiab kev tuav nruj thaum thauj khoom thiab tshem tawm. Lub siab elongation thaum so kom ntseeg tau tias lub hnab tuaj yeem tswj tau qhov kev ntxhov siab thiab tiv thaiv cov khoom poob.
Kev tsim kho
Hauv kev tsim kho kev lag luam, PVC jumbo hnab yog siv los nqa cov xuab zeb, pob zeb, cement, thiab lwm yam khoom siv hauv tsev. Lub hnab yuav tsum tau hloov tau yooj yim kom tau ntim thiab ntim tau yooj yim, thiab muaj zog txaus los tiv thaiv qhov hnyav ntawm cov ntaub ntawv. Ib qho zoo elongation ntawm kev so yog qhov tseem ceeb rau kev ua kom lub zog ntawm lub hnab nyob rau hauv qhov chaw xav tau.
Tshuaj
PVC jumbo hnab kuj tseem siv los thauj thiab khaws cov tshuaj. Cov hnab no yuav tsum tiv taus cov tshuaj lom neeg thiab muaj qhov elongation siab ntawm kev tawg kom tsis txhob xau thiab nchuav. Peb lub hnab PVC jumbo yog tsim los ua kom tau raws li cov kev cai nruj ntawm kev lag luam tshuaj.
Xaus
Hauv kev xaus, qhov elongation ntawm kev tawg ntawm PVC jumbo hnab yog cov cuab yeej tseem ceeb uas cuam tshuam rau lawv cov kav ntev, hloov tau, thiab kev nyab xeeb. Los ntawm kev nkag siab txog cov cuab yeej no thiab xaiv cov hnab nrog lub siab elongation thaum so, koj tuaj yeem xyuas kom meej tias koj cov khoom raug thauj thiab khaws cia zoo thiab ua haujlwm zoo.
