Lub luag haujlwm ntawm Polypropylene Fiber hauv mortar
Jul 14, 2023| Lub luag haujlwm ntawm Polypropylene Fiber hauv mortar yog dab tsi?
1. Txhim khu lub zog tensile ntawm mortar
Ntxiv polypropylene fiber ntau rau mortar tuaj yeem txhim kho lub zog tensile ntawm mortar. Raws li cov khoom siv nkig, mortar yog qhov ua rau tawg thaum raug tensile load, thiab ntxiv ntawm polypropylene fiber tuaj yeem tiv taus tensile load los ntawm sab hauv, kom lub tensile kev ua tau zoo ntawm mortar yog txhim kho.
2. Ua kom lub zog compressive ntawm mortar
Lub mortar yog nquag tawg thaum nws nyob rau hauv siab, uas cuam tshuam rau lub neej kev pab cuam ntawm lub mortar. Los ntawm kev ntxiv polypropylene fiber ntau, compressive zog ntawm mortar tuaj yeem nce ntxiv, ua rau nws ruaj khov dua. Polypropylene fiber ntau tuaj yeem ua rau muaj kev sib koom ua ke ntawm mortar, txhim kho kev ruaj ntseg ntawm mortar, thiab yog li ua kom lub zog compressive ntawm mortar.
3. Txhim kho qhov hnav tsis kam ntawm mortar
Thaum lub sij hawm ntev siv mortar, nws yog ib qho yooj yim rau hnav thiab puas vim kev sib txhuam thiab pedaling ntawm hauv av. Qhov sib ntxiv ntawm polypropylene fiber ntau tuaj yeem txhim kho qhov hnav tsis kam ntawm mortar thiab txo qis kev hnav. Polypropylene fiber ntau tuaj yeem tsim cov qauv fiber ntau, ua kom lub zog thiab hardness ntawm mortar, yog li txhim kho qhov hnav tsis kam ntawm mortar.
4. Txhim kho qhov tawg tsis kam ntawm mortar
Hauv kev tsim kho vaj tse, mortar feem ntau cuam tshuam los ntawm cov yam ntxwv xws li kev nthuav dav thiab kev cog lus, kev sib haum xeeb thiab kev hloov pauv kub, thiab nws yuav ua rau tawg. Qhov sib ntxiv ntawm polypropylene fiber ntau tuaj yeem txhim kho qhov tawg ntawm cov tshuaj khib nyiab, ua rau nws tsis tshua muaj kab nrib pleb. Deyang polypropylene fiber ntau tuaj yeem ua rau cov ductility ntawm mortar, yog li txo qhov deformation ntawm mortar thiab tsis yooj yim los tsim cov kab nrib pleb.
