Qhov zoo ntawm polypropylene pp ntawv
Cov ntaub ntawv tawv yas muaj cov khoom siv hluav taws xob uas tsis tshua muaj kev sib txhuam uas yog qee qhov zoo tshaj plaws hauv kev ua haujlwm ntawm tshuab plastics thiab daim ntawv yas tawv coj los pab tsim cov kev sib txhuam qis. HDPE Sheet kuj muaj kev tiv thaiv zoo heev uas pab muab cov khoom sib dhos uas tsim nyog rau kev ua haujlwm siab. HDPE Sheet yuav nqus cov dej noo ntau ntau uas pab tsim cov khoom sib txawv uas ruaj khov nyob rau lub sijhawm ntev thiab tseem yuav pab cov khoom no tau txais Cov Khoom Noj & Tshuaj Tso Cai Pom Zoo uas tuaj yeem pab hauv kev lag luam khoom noj khoom haus.
Pvc daim ntawv yas yog qhov pheej yig heev thiab tuaj yeem muab kev txhim kho yas engineering nrog kev sib txig sib luag los yog ntau dua kev ua tau zoo thiab txuag tau cov neeg siv nyiaj kawg tus nqi ntau. HDPE Sheet yog lub teeb thiab yooj yim siv tshuab kom pab txhim kho cov sij hawm machining. HDPE Sheet yog cov tawv heev thiab yuav luag tsis tuaj yeem tawg uas pab tsim cov khoom sib tw uas tawv thiab tuaj yeem sawv ntau qhov kev rau txim hauv qhov chaw muaj kev cuam tshuam loj.
Cov ntawv thov rau pol y propylene pp ntawv
Yas pvc daim ntawv yog ib qho kev ua tshuab yas tau zoo rau kev lag luam khoom noj khoom haus qhov twg kev sib txhuam qis thiab tsis tuaj yeem rau ntawm cov kab tsim khoom noj yog qhov tseem ceeb. HDPE Sheet kuj tseem ceeb nyob hauv kev lag luam dej thiab HDPE Ntawv pom muaj nyob rau ntau qhov chaw ntawm kev lag luam no vim nws qhov kev nqus noo tsawg thiab cov tshuaj tiv thaiv zoo.
Xov xwm tshiab
Qhov tseeb, peb paub tias cov yam ntxwv ntws ntawm PVC yas ntawv zoo tsis ntau thiab lawv cov txheej txheem ntau yog nqaim heev. Hauv tshwj xeeb, cov khoom siv loj hauv qhov hnyav PVC PVC cov txheej txheem nyuaj rau kev ua, yog li cov ntawv me me molecular phaus PVC cov ntaub ntawv feem ntau siv. Lub shrinkage tus nqi ntawm PVC yog heev tsawg, feem ntau 0.2 ~ 0.6%. PVC yas ntawv muaj cov pa taws tsis zoo, lub zog loj, tiv taus cov roj thiab muaj kev ruaj ntseg zoo geometric. Niaj hnub no, peb tuaj tham nrog koj txog kev ua tau zoo ntawm PVC yas pawg thawj coj saib kev paub txog cov xwm txheej!
Kev Ntsuas Ua Tau Raws Li Pvc Cov Paib Daim Hlau
1, Pvc daim ntawv yas ua tiav kev txheeb xyuas-cov khoom siv zoo: PVC yas ntawv yas muaj qhov siab hardness thiab cov khoom siv tshuab. Nws nce nrog qhov nce ntawm molecular phaus, tab sis poob nrog qhov nce ntawm qhov kub. Cov cuab yeej lub zog ntawm cov tawv tawv PVC yas daim hlau muaj qhov zoo, thiab lawv cov txheej txheem elastic tuaj yeem ncav cuag 1500-3000 MPa. caij nyoog kev sib txawv ntawm cov tawv mos PVC yog 1.5-15 MPa.but qhov tawg ntawm elongation yog kom ntau li 200% -450%. Kev sib txhuam ntawm PVC yog qhov dav dav, qhov kev sib txhuam zoo li qub yog 0.4-0 .5, thiab qhov sib txhuam tsis sib luag yog 0.23.
2, Pvc yas pawg thawj coj saib kev ua tau zoo-kev ua tau zoo: kev ua tiav PVC cob yog hmoov dawb lossis lub teeb daj, tus txheeb ze ntawm 1.35-1.45. Cov qib ntsuas ntawm qhov muag ntawm cov khoom tuaj yeem hloov kho los ntawm kev ntxiv cov naj npawb ntawm cov yas. Cov ntshiab PVC muaj dej tsis tshua muaj dej thiab huab cua permeability.
3, Pvc yas board ua tiav kev txheeb xyuas-hluav taws xob ua tau zoo: mos PVC board yog ib hom polymer nrog kev ua tau zoo hluav taws xob, tab sis vim nws qhov loj polarity, hluav taws xob rwb thaiv tsev tsis zoo li PP board thiab PE yas board. Lub dielectric tas mus li, qhov zoo tangent ntawm dielectric poob lub kaum ntse ntse thiab volumetric resistivity yog qhov loj, thiab corona tsis zoo. Nws yog feem ntau haum rau nruab nrab tsis tshua muaj siab thiab tsawg zaus hluav taws xob cov ntaub ntawv.
4, Pvc yas pawg thawj coj saib kev ua haujlwm-kev ua tau zoo: kev ua tiav PVC yas phaj thermal stability yog qhov tsis zoo heev, 140 ° C pib ua kom zoo, yaj kub ntawm 160 ° C. Txoj kab nthuav dav coefficient ntawm PVC yog qhov me me, nws yooj yim, thiab qhov ntsuas oxidation yog siab li 45 lossis ntau dua.
Pvc cov ntawv yas ua tiav-ib puag ncig kev ua tau zoo: PVC tuaj yeem tiv taus cov tshuaj tiv thaiv feem ntau cov kua qaub, cov hauv paus, cov ntsev, cov kuab tshuaj organic feem ntau. Haum rau tshuaj, tshuaj lom neeg cov khoom siv antiseptic.
Ob lossis rau lus qhia txhawm rau kawm paub yuav ua li cas paub qhov ua tau zoo ntawm PVC yas phaj:
1) Saib nws cov duab ci: Qhov sib txawv ntawm gloss yog rov qab siv dua yas, tsis yog PVC.
2) Kev ua siab ntev: Kev ua dua tshiab yas kuj tseem ntau dua.
3) Saib rau qhov txiav chaw: cov yas siv dua tshiab yuav muaj xim sib txawv tom qab txiav.
4) Qhov ceev: Muab cov dej pov tseg kom pom tias nws ntab rau dej, thiab feem ntau ntawm kev tsim kho tshiab yog sunk.
5) Kev kho cua sov: Cov tshuab hluav taws xob rov qab tshiab yuav muaj pa taws thaum welded.
6) Transparency: PVC yas daim hlau muaj lub teeb zoo permeability.
