Feem ntau, manufacturers siv PVC ntug banding los txhim kho qhov teeb meem ntawm burrs thaum tsim thiab kho vaj huam sib luag rooj tog. Kev siv cov kab txaij zoo nkauj cuam tshuam ncaj qha rau kev zoo nkauj thiab kev ua haujlwm ntawm rooj tog. Yuav kom ua tau raws li qhov yuav tsum tau ua ntawm cov rooj tog zoo nkauj thiab kev tiv thaiv, nws yog ib qho tsim nyog yuav tsum ua kom tiav cov ntug sealing ua haujlwm ntawm rooj tog raws li kev siv zoo tagnrho. Yog li, dab tsi yog qhov chaw zoo tshaj plaws rau kev siv ntug banding?
1. Kub
Qhov zoo tshaj plaws kev khiav hauj lwm kub rau ntug banding yog 190 ~ 210 degree, tab sis vim txawv hom thiab qauv ntawm kub yaj nplaum nplaum, ib puag ncig ntawm 120 ~ 190 degree kuj raug xaiv raws li lawv cov yam ntxwv. Raws li qhov kub thiab txias, lub zog sib txuas ntawm ntug banding tseem yuav txhim kho, yog li nws raug pom zoo kom siv cov nplaum kub kub yaj nplaum kom ua tiav qhov zoo tshaj plaws ntug banding nyhuv.
2. Ntug angular tshaj tawm.
Yog hais tias lub thickness ntawm ntug banding strip yog tsawg dua 0.6mm, lub ntug banding strip yuav muaj softening thiab stretching thaum lub sij hawm ntug banding txheej txheem. Qhov tshwm sim ntawm deformation thiab lwm yam tshwm sim yog vim qhov qeeb ntawm ntug banding ceev thiab lub sij hawm ntev melting thiab tuav lub sij hawm ntawm kub yaj nplaum. Txhawm rau hais txog qhov tshwm sim no, lub ntug banding ceev tuaj yeem ua kom nrawm los ntawm kev siv cov hlua siv high-speed conveyor.
Cov yam ntxwv uas cuam tshuam rau ntug banding tsis txwv rau saum toj no ob yam. Raws li ntug banding tshuab muaj kev txhawj xeeb, qhov zoo tshaj plaws ntug banding ib puag ncig yuav tsum raug xaiv thiab ntug banding cov cai yuav tsum tau ua raws li txhawm rau txhawm rau daws cov teeb meem ntawm rooj tog zaum.
