Qhov loj me ntawm kev kub ntsws tubing yog tsuas yog txhais los ntawm nws cov taub sab hauv, cov nqi ntsws, phab ntsa thickness thiab lwm yam. Cov hauv qab no yog cov lus piav qhia tshwj xeeb:
1. Sab hauv taub
Qhov loj me ntawm kev ua kom sov ntsws tubing feem ntau yog qhia raws li "φ + tooj", xws li "}. {}", Hauv millimeters (hli). Tus naj npawb ntawm no hais txog lub taub sab hauv ntawm tshav kub ntsws tubing ua ntej shrinkage, uas yog, lub taub sab hauv loj thaum tsis rhuab.
Qee cov cua sov ntsws tubing yuav cim "φ3. {}}}}}}}}} Sawv cev rau lub taub sab hauv tom qab shrinkage. Txoj kev kos duab no tuaj yeem nkag siab txog qhov ua kom muaj peev xwm ntawm lub peev xwm ntawm kev ua kom sov.
2. Shrinkage tus nqi
Shrinkage tus nqi yog hais txog qhov sib piv ntawm cov taub sab hauv ntawm lub tshav kub ntsws tubing ua ntej thiab tom qab cua sov. Piv txwv li, A φ6. {{{{{0 sov ntsws tubing shrinks rau φ3. {} Tom qab shrinkage, thiab nws shrinkage tus nqi yog 2: 1. Cov nqi shrinkage yog 2: 1, 3: 1, 4: 1, thiab lwm yam.
Lub siab dua shrinkage tus nqi, tus me dua sab hauv lub taub ntawm tshav kub ntsws tubing tom qab nws yog qhov tsim nyog rau cov cable thlesles lossis khoom.
3. Phab ntsa tuab
Phab ntsa tuab yog hais txog qhov tuab ntawm phab ntsa ntawm lub tshav kub ntsws tubing, uas cuam tshuam nws lub peev xwm kho tshuab. Lub thicker phab ntsa, qhov zoo dua kev tiv thaiv kev ua tau zoo ntawm lub tshav kub ntsws tubing.
Nws yuav tsum raug sau tseg tias lub phab ntsa tuab ntawm lub tshav kub ntsws tubing yuav nce ntxiv, saib xyuas cov phab ntsa tuab tom qab nws ua lub luag haujlwm tiv thaiv.
4. Kev xav tau kev txiav txim siab
Thaum nriav kev kub ntsws tubing, lub neej ntawd feem ntau yog hais txog lub taub sab hauv ua ntej yuav tawg. Piv txwv li, rau ®3. {{{{Mm} mm tshav kub ntsws tubing, cov chaw tsim tshuaj kub ua ntej yuav tawg yog 3. {{Mm.
Yog tias muaj kev sib tw ua tiav, nws raug nquahu kom paub meej tias lub taub hau sab hauv ua ntej thiab tom qab ua kom sov ntsws tubing tuaj yeem npog thiab tiv thaiv lub hom phiaj.
5. Lwm yam tsis muaj
Shrinkage kub: qhov kub ntawm cov cua sov tubing pib ntsws, piv txwv li, qhov ua kom txaus ntshai, kev kub ntxhov ntawm PE Thaum Tshav Kub Kub Tube yog 84 degree.
Kev ntsuas kub zaum kawg: Qhov ntsuas kub yuav tsum tau rau lub tshav kub ntsws tubing los ntsws kom tiav, 120 degree.
Kev ua haujlwm kub: Qhov ntsuas kub nyob rau hauv uas sov ntsws tubing yog ib txwm siv, piv txwv li, {0} degree rau 125 degree.
Lub ntsiab
Qhov loj ntawm tshav kub ntsws tubing yog tsuas yog txhais los ntawm sab hauv intern ua ntej shrinkage, thiab phab ntsa thickness. Thaum kev yuav khoom, cov teeb meem no yuav tsum tau lees paub raws li qhov kev xav tau tiag tiag kom ntseeg tau tias cov cua sov shrink tubing tuaj yeem ua tau raws li kev cai ntawm kev siv. Yog tias koj xav paub ntau ntxiv txog cov qauv lossis cov xwm txheej tsim nyog, koj tuaj yeem tshawb rau lub tshav kub ntsws tubing tshwj xeeb cov qauv lossis hluav taws xob ua kom sov
