1. Kev nplij siab thiab kev nyab xeeb: Cov ntaub qhwv muaj tsawg tsawg tom qab ziab, thiab yuav tsis ua rau tsis xis nyob xws li nruj los yog khaus ntawm daim tawv nqaij tom qab cov ntaub qhwv plaster dries. Kuj tseem yuav tsis muaj cov tshuaj tiv thaiv tshav kub thaum lub sij hawm hardening txheej txheem ntawm gypsum, thiab tus neeg mob cov tawv nqaij yuav tsis xis nyob nrog ib tug kub hnyiab tau thaum nws absorbs dej thiab recrystallizes.
2. Kev ua pa zoo: Cov ntaub qhwv siv cov ntaub qhwv ntsej muag zoo, uas muaj qhov ua pa zoo thiab daws qhov tsis xis nyob ntawm daim tawv nqaij kub thiab khaus khaus tshwm sim los ntawm kev ua tsis taus pa tsis zoo vim lub raj xa dej hauv zos mus ntev.
3. Lub teeb yuag thiab siab hardness: Tom qab kev sim, qhov hardness ntawm cov ntaub qhwv kho yog 20 npaug ntawm cov ntaub qhwv plaster ib txwm, uas ua lub luag haujlwm txhim khu kev qha hauv kev tswj xyuas kom raug. Cov khoom siv ruaj khov yog qhov tsawg thiab lub teeb, sib npaug rau 1/5 ntawm gypsum, uas tuaj yeem txo qhov hnyav ntawm thaj chaw cuam tshuam thiab txhawb cov ntshav ncig hauv zos thiab kho.
4. Kev Tshaj Tawm Zoo Tshaj Plaws: Cov pob txha thiab cov ntaub qhwv muaj pob tshab zoo heev rau cov hluav taws xob thiab cov txiaj ntsig X-ray kom pom tseeb, kom ntseeg tau tias cov kws kho mob tuaj yeem tuav cov pob txha sib txuas thiab kho qhov chaw cuam tshuam.
5. Cov dej tsis zoo: Cov ntaub qhwv muaj cov dej tsis zoo thiab tuaj yeem thaiv 85% ntawm cov dej noo sab nraud los ntawm kev nkag mus rau hauv.
6. Yooj yim rau kev khiav lag luam, yoog raws, thiab muaj cov yas zoo: Thaum muaj kev raug mob ntawm daim tawv nqaij sab nraud lossis lub sijhawm ua haujlwm ntev ntawm qhov chaw ruaj khov, nws tuaj yeem kho ncaj qha yam tsis muaj ntub dej ua ntej. Tom qab kho, dej tuaj yeem txau rau ntawm txheej txheej ntawm pob kom nrawm nrawm nrawm. Zoo plasticity, siab khoov thiab tensile lub zog, tuaj yeem khoov tau yooj yim, thiab cov ntaub qhwv tuaj yeem ua rau hauv cov duab, kev txhawb nqa, thiab clamps.
7. Muaj feem xyuam: orthopedic fixation, orthopedic cov cuab yeej siv rau kev phais yas, cov khoom siv prosthetic, cov cuab yeej txhawb nqa. Cov chaw tiv thaiv hauv zos hauv chav haujlwm hlawv, thiab lwm yam.
