Cov kev ceev faj rau TPU / PVC coated webbing hauv cov txheej txheem ntau lawm

TPU / PVC coated webbing yog lub vev xaib tshiab ua webbing tshiab tsim los hloov tsoos nylon webbing. Nws lub ntsiab qauv yog nylon lossis (polyester) webbing. Nws yog tsuas yog siv rau tsiaj webbing thiab tsheb leeg. TPU / PVC coated webbing yog zam, ruaj thiab yooj yim ntxuav thiab muaj zog. Nws ua ke ntawm cov khoom sib xws ntawm TPU / PVC kom ua cov nylon webbing tom qab npog cov kua nplaum ntau dua thiab siv dav hauv.

Peb yuav tsum them sai sai rau cov teeb meem hauv cov txheej txheem tsim cov khoom lag luam zoo TPU / PVC coated webbing. Peb wil tu ntau txoj hauv kev ntawm kev xaiv, kev npaj, molding, traction thiab ntim.

Ob peb lub ntsiab lus tseem ceeb ntawm qib siab zoo TPU / PVC coated webbing:

1. TPU / PVC thiab webbing muaj muaj zog txhaws ua kom ceev nrawm;

2. Qhwv webbing tsis muaj streaks thiab npuas ；

3. Tom qab webbing yog coated, tus webbing yog nyob hauv nruab nrab txoj hauj lwm ；

4. Dyed TPU / PVC nto yuav tsis ploj;

5. Lub sijhawm ntev, TPU / PVC coated webbing tsis tau tig ua dawb, muag lossis tig daj.

1.Material xaiv: TPU / PVC khoom siv thiab webbing

Dab tsi ntawm TPU / PVC cov khoom haum rau qhwv lub vev xaib, nws yuav tsum yog extruded TPU / PVC cov khoom, qhov tawv yog 80A ~ 95A yog qhov zoo tshaj plaws, qhov no tuaj yeem ua raws li qhov muag muag thiab tawv ntawm cov khoom nws tus kheej. TPU / PVC khoom hardness kev kho kom haum, feem ntau xaiv 85A cov khoom siv yog haum dua; yog tias xaiv ntau dhau, lub zog tsis dhau, xaiv cov khoom siv TPU / PVC nyuaj dhau, lub vev xaib yog qhov nyuaj dhau, tsis tuaj yeem ua tiav zoo tes. Cov khoom siv polyester tseem raug xaiv los ua cov khoom siv polyether, uas yog xaiv raws li kev siv cov khoom siv ntawm nws tus kheej. Yog tias nws tiv taus rau qhov kub tsawg, hydrolysis, thiab muaj qhov sib chwv zoo, polyether hom TPU siv tau; Yog tias nws xav tau cov cuab yeej zoo muaj zog, tiv tshav kub, tiv taus qws thiab lwm yam uas yuav tsum tau ua, polyester TPU tuaj yeem xaiv; Hauv cov txheej txheem ntawm TPU, lub ntsiab lus tseem ceeb tshaj plaws rau kev ceeb toom yog tias yuav tsis muaj qhov tshwm sim ntawm txau pom hmoov tom qab ntev ntev. Qhov no yog qhov tshwm sim feem ntau ntawm polyester TPU. Qhov no yog qhov tseem ceeb tshwj xeeb hauv kev xaiv TPU cov ntaub ntawv;

Cov nplaim hluavtaws-kov cov qhov webbings yuav tsum siv cov khoom tiv thaiv TPU-nplaim hluav taws. Feem ntau, cov ntaub ntawv qhia qib TPU zoo tib yam tsis muaj txoj hauv kev raws li cov khoom xav tau. Cov nplaim hluav taws-qib rov qab muaj V0 qib, V1 qib, thiab muaj pa taws thiab tsis muaj pa taws thiab tsis pub muaj kev tiv thaiv ib puag ncig kev tiv thaiv, yog li yog tias koj xaiv qee qhov kev nyab xeeb thiab kev tiv thaiv ib puag ncig, koj yuav tsum siv nplaim hluav taws kub retardant TPU cov ntaub ntawv, thiab xav tau cov khoom lag luam muab cov ntawv pov thawj coj ua tiav ua ntej lawv tuaj yeem siv.

2. Qhov kev xaiv ntawm webbing tuaj yeem siv rau txheej webbing.

Cov webbing uas tau xaiv yuav tsum tau siv rau qhov kub thiab txias tiv thaiv webbing. Dab tsi yog qhov kub thiab txias tsis kam? Vim tias qhov webbing hla ntawm qhov cub thaum lub sijhawm txheej txheem ntau lawm, qhov kub thiab txias feem ntau yog 130 ℃, thiab qhov ntsuas kub tau nce mus txog 160 ℃. Yog li, lub webbing yuav tsum dhau los ntawm qhov kub siab. Tom qab kho, lub webbing loj yog ruaj khov dua; yuav tsis muaj shrinkage thaum lub sij hawm ua txheej txheej; ntxiv rau qhov hla dhau ntawm lub qhov cub, qhov webbing yuav tsum dhau los ntawm qhov kub tuag, thiab qhov kub ntawm qhov tuag yuav ncav cuag 200 ℃, Yog tias lub webbing tsis tuaj yeem tiv taus qhov kub siab, nws yuav ya thaum nws ntsib qhov kub. Nws yuav tsis ruaj khov rau hauv txheej txheej TPU / PVC txheej txheem, thiab nws yuav tsis ncav cov kev xav tau webbing.At tib lub sijhawm, qhov ntom ntom ntom ntawm cov ntaub qhwv lub webbing yuav tsum muaj qhov siab, tsis dhau xoob, txhawm rau tiv thaiv lub webbing los ntawm ntsib qhov kub siab ntog. thaum lub sij hawm traction txheej txheem. Webbings feem ntau yog ua los ntawm nylon webbing lossis polyester webbing.

Lwm cov ntawv sau: ua tiav ntawm qhov webbing thiab txaus txias ntawm TPU / PVC cov khoom

1. Ua tiav qhov webbing

Ua ntej yuav muab cov ntaub qhwv webbing, nws yog qhov tseem ceeb heev kom tiav qhov webbing uas yuav tsum tau ua kom npog. Lub vev xaib yog kev kho cua sov kom tiv thaiv lub webbing los ntawm kev zawm thaum lub siab kub thaum lub txheej txheej.Vim li cas ntawm qhov kawg ntawm lub webbing yog qhov tseem ceeb? Thaum lub webbing nyob rau hauv tus txheej txheem ntawm traction, nws ib txwm nyob hauv qhov ceev. Yog tias qhov webbing tsis tiav, thaum muaj qhov ntxeev, nws tsis muaj txoj hauv kev los nres thiab kho, nws yuav txuas ntxiv mus rau hauv cov kev taw qhia ntawm traction, thiab lub nkhaus webbings tsis tuaj yeem hla dhau. Tom qab ntawd lub webbings yuav tsum tau txiav thiab rov nkag rau hauv cov pwm qhov ncauj. Lub sijhawm no, tib lub sijhawm, TPU / PVC cov khoom siv yuav txuas ntxiv mus, yuav ua rau cov khib nyiab loj thiab ploj, yog li ua ntej txheej txheej, webbing xov ua haujlwm yog qhov tsim nyog heev.

2. Kev tsim nyog txias ntawm TPU / PVC cov khoom

Thaum TPU / PVC raug coated, nws yog melted los ntawm tus tswv tsev ntawm qhov kub thiab, thiab tsuas yog txias thiab tsim nyob rau hauv lub thawv dej txias. Yog tias cov dej txias tsis ncav cuag cov nyhuv txias, cov dej tsaws lossis cov npuas tshwm nyob rau sab saum toj ntawm TPU / PVC tom qab txheej txheej, TPU / PVC thiab Nylon webbing muaj txheej xim tsis txaus, uas ua rau nws yooj yim rau delaminate TPU / PVC thiab webbing, thiab tsis tuaj yeem ua tiav cov xim txheej; siab txias TPU / PVC, nto nto zoo thiab zoo, TPU / PVC thiab webbing txheej nyhuv yog khov kho; tshwj xeeb tshaj yog TPU / PVC Thaum nws tseem nyob rau hauv kev sib cuag nrog lub taub dej txias, nws yuav tsum txias kom txias txaus. Tso ob peb ntau lub taub hau txias dua, thaum nws nkag mus rau hauv dej, tag nrho txias lub vov webbing kom lub webbing yog flatter thiab yuav tsis deformed.
