Qhov ceev ntawm lub hlwv hluav taws xob ntim tshuab sib txawv raws li cov qauv khoom siv, kev tsim khoom, thiab cov khoom ntim ntim ntau lawm, thiab cov khoom siv ntim khoom.
1. Khiav ceev
Cov hlwv hluav taws xob ntawm lub hlwv ntim ntim feem ntau yog ntsuas los ntawm cov hlwv uas tuaj yeem ua tiav ib feeb lossis khiav mus ntev ntawm lub pvc npuas nyob.
Tus naj npawb ntawm cov hlwv hauv ib feeb:
Cov khiav ceev ntawm lub tiaj hlwv hlwv ntim ntim feem ntau yog ntawm 30 thiab 60 tus hlwv hauv ib feeb. Qhov kev nrawm no tuaj yeem ua tau raws li cov kev xav tau ntawm cov neeg tsim khoom lag luam feem ntau thiab ua kom cov sib npaug ntawm cov khoom lag luam ntau lawm thiab ntim khoom zoo. Txawm li cas los xij, qhov ceev tshwj xeeb tseem yuav cuam tshuam los ntawm cov qauv khoom siv, kev tsim khoom, thiab cov xwm ntawm cov khoom ntim ntim.
Khiav Tshwm Sim Ntawm PVC Npuas Notes Cov Ntawv:
Cov khiav ceev ntawm PVC npuas lotes cov ntawv ntawm ib co hlwv ntim ntim tuaj yeem ncav cuag 2.5 ~ 3.5 meters / feeb. Qhov taw qhia ceev no qhia ntau dua lub peev xwm ntawm lub hlwv ntim tshuab los lis cov ntaub ntawv txuas ntxiv.
2. Xev Ntaus
Punching yog qhov tseem ceeb hauv lub hlwv ntim tshuab, uas txiav txim siab muaj pes tsawg tus hlwv tuaj yeem tsim thiab txiav ib feeb. Cov punching nrawm yog feem ntau ntsuas los ntawm cov punchings ib feeb.
Dav Punching Ceev:
Cov punching ceev ntawm cov hlwv tuaj ntim tshuab feem ntau yog nruab nrab 28 thiab 40 zaug / feeb. Qhov kev nrawm no tuaj yeem ua kom cov moulding zoo thiab txiav qhov tseeb ntawm cov hlwv.
Kev kub ceev punching:
Qee qhov kev ua qauv siab ntawm cov hlwv tuaj ntim tshuab lossis cov qauv nrog cov kev tsim tshwj xeeb yuav tau siv dua punching nrawm. Piv txwv li, zaus punching ntawm DPT220 cov menyuam hlwv luam yeeb tuaj yeem ncav cuag li 150 zaug / feeb.
3. Txom Nyem Cov Lus Qhia
Qhov ceev ntawm lub hlwv ntim ntim cuam tshuam los ntawm ntau yam, suav nrog tab sis tsis txwv rau cov hauv qab no:
Cov qauv khoom siv: qauv sib txawv ntawm cov qauv ntim tshuab sib txawv hauv cov qauv tsim, qauv thiab kev ua haujlwm nrawm kuj tseem sib txawv.
Chaw Tsim Tshuaj Ntau Lawm: Yam Khoom xws li kub, av noo, thiab huv ntawm kev ua haujlwm ntau dhau ntawm lub hlwv ntim tshuab.
Ntim Khoom Siv Khoom Siv: Cov tuab tuab, Hardness, hardness, viscoidosity thiab lwm yam khoom ntawm cov kev khiav nrawm ntawm lub hlwv ntim tshuab. Siv cov ntaub ntawv ntim tsim nyog tuaj yeem txhim kho kev ua haujlwm ntawm cov khoom siv.
