Tsim
Feb 25, 2016

Ob tug menyuam qhib rau lub calender tsim-yob yog cov qauv tseem ceeb, muaj xaiv yuav tej khoom tawg yooj yim thiab ua deg thiab tsis cuab, raws li ntawm txoj kev ua configuration. Rau cov menyuam hom qauv, peb muaj coj txawv nyob rau hauv roj hmab thiab tshuaj yas industries tus menyuam Super txoj kab uas hla qhov siab tsim, qhov siab = (D-d) / 2, raws li muaj nyob hauv daim duab 7. Tsim kom muaj los txhawb rau cov dov yob dabtsi yog khoov deformation kev nyuab siab, thiab ua kom qhov chaw ntog ntawm cov hwjchim ntxuag, quab yuam sib nqus hais ntws ob txoj kev, thaum dov tej zaum tus rolls kev txawv cov cua kub, yog tsim rau cov cua kub chav hollow yob thiab nyob ib ncig ntawm drilling rau cov roj cua sov thiab cua sov chais dej. Pab ntau lawm, ob cua kub txoj kev yuav ntsib hauj yuav tsum yob deg kub fluctuations. Saib raws cai khoom tawg yooj yim, peb siv kuj coj zoo, nws rigidity alloy muab hlau cam khwb cia cov menyuam ua deg hardness txog HS72 ~ 75. Alloy muab cam khwb cia hlau yob muaj feem ntau uas yog tsis xws luag, thiab cov additives hauv pub tej zaum muaj nyob rau lub corrosive los ntawm yob nto, uas ua rau lub sij hawm luv luv uas siv rau cov menyuam nto tshwm tom qab "ka-huab" uas tsis tau raug kuav los tiag ntawm du nplaim sib nqus phaj, vim li ntawd tus menyuam qhov chaw yog ib tug txheej txheem uas tshwj xeeb yog tsim nyog. Yoog tshwj xeeb yog mas deg txau coj-resistant ntaub ntawv thiab hnov chromium plating ob txoj kev, peb siv lub tom kawg. Yuav txhim khu lub zog nyiaj ntawm tawv chrome thiab alloy cam khwb cia muab hlau, chrome-plating ua ntej npib tsib xee plating, chromium plating thickness txheej tom qab sib tsoo no feem ntau 0.05 ~ 0.08 hli. Particular ua ntawd, thaum lub sijhawm ntau lawm ntawm ib PVC zaj duab xis muag plywood, kab rov tav ob-cov menyuam rolling zeb lub zoo tshaj configuration ua ib chrome-plated chais, rau lub alloy leeg khov lawm rhaub yob hlau cam khwb cia. Vim sib nqus alloy khov lawm rhaub cam khwb cia hlau yob phaj ntxuag nto kuj ntxhib, pab kom tsevneeg zog sib nqus daim hlau thiab PVC zaj duab xis.
