Niaj hnub no peb yuav tham txog txheej txheej ntawm cov khoom siv sheath rau cov xov hlau thiab cables. Cov kws tshaj lij nyob rau hauv daim teb no, nrog rau kev yuav khoom thiab tsim cov engineers, yeej paub cov npe TPE thiab PVC. Peb yuav tsum siv leej twg, ib qho thov ua lub hnub qub nce hauv kev tiv thaiv ib puag ncig thiab lwm tus thov ua tus huab tais ntawm tus nqi-kev ua tau zoo?
Ua ntej, cia peb nkag siab tias lawv yog dab tsi.
TPE raws li cov ntaub ntawv sheath ntawm cable lossis tswj cable, nws yog ib qho thermoplastic elastomer, uas tuaj yeem xav txog qhov zoo tshaj plaws thiab rov ua dua "rubber band". Nws yog yug los nrog elasticity thiab saj zawg zog ntawm roj hmab, muaj tes zoo, thiab tuaj yeem rub rov qab rau lub sijhawm ntev nrog lub swoosh. Qhov tseem ceeb tshaj plaws yog tias, zoo li cov yas, nws melts thaum rhuab thiab tuaj yeem rov ua dua yam tsis muaj sij hawm- siv thiab lub zog siv cov txheej txheem "vulcanization" uas cov roj hmab tsoos yuav tsum tau ua. Cov hom muaj xws li SEBS raws li cov uas muaj kev xav zoo thiab huab cua tsis zoo.
Thiab PVC li rwb thaiv tsev los yog sheath khoom ntawm hluav taws xob cable, tseem hu ua polyvinyl chloride, zoo li ib tug oily "rubber putty". PVC ntshiab yog tawv thiab siv tsis tau. Cov mos PVC peb siv nyob rau hauv peb cov xov hlau yog softened los ntawm kev ntxiv ib tug loj npaum li cas ntawm "plasticizers" (xws li hom DOP). Yog li nws softness yog "soaked" tawm. Raws li rau kev ua tau zoo, nws tag nrho yog nyob ntawm seb cov qauv twg ntxiv. Nws yog pheej yig thiab ib txwm nplaim taws retardant, tab sis nws yog feem ntau muaj teeb meem nyob rau hauv cov nqe lus ntawm kev tiv thaiv ib puag ncig thiab kub kuj.
Tsuas paub tias nws yog dab tsi tsis txaus. Tom ntej no, cia peb piv lawv cov kev ua tau zoo.
| Qhov project piv | TPE khoom ntawm Cable los yog tswj cable | PVC khoom ntawm Cable los yog fais fab tswj cable |
| Texture thiab elasticity |
Zoo elasticity, du los yog roj hmab zoo li xav, ceev rebound thaum pinched, tsis yooj yim deformed. |
Plasticity muaj zog, tej zaum yuav muaj indentations nyob rau hauv lub sij hawm, thiab tej zaum xav tias nplaum los yog ntxhib rau qhov kov. |
| Kub-resistant | Ntau yam, cov zoo tuaj yeem tiv taus qhov kub ntawm -60℃txog 135 degree, thiab nyob twj ywm hauv lub caij ntuj no. | Qhov ntau yog nqaim, feem ntau ntawm -15℃mus rau 105 degree. Nws ua nkig thaum nws txias dhau thiab nquag ua kom tawv thiab laus thaum nws kub dhau. |
| Kev tiv thaiv ib puag ncig | Zero halogen, cov pa luam yeeb tsawg, tsis yog - lom, kub hnyiab zoo li tswm ciab, nrog cov pa taws tsawg dua thiab tsw ntxhiab tsw. Tsis muaj cov tshuaj phem xws li ortho benzene. | Cov tshuaj chlorine muaj, nplaim hluav taws zoo tab sis muaj kuab lom vim muaj pa taws siab, nrog rau cov kua qaub qaub thiab cov pa luam yeeb dub thaum hlawv. Qee cov plasticizers tsis yog ib puag ncig zoo. |
| Roj-resistant | Qhov nruab nrab TPE yog qhov nruab nrab, tab sis tshwj xeeb TPV yog cov roj resistant heev. | Tsis zoo rau cov ntxhia roj, roj av, thiab lwm yam, nws yooj yim rau o thiab viscosity. |
| Machineability | Kev ua haujlwm yooj yim, tsis tas yuav ziab thiab vulcanization, ceev extrusion, thiab tag nrho cov ntaub ntawv pov tseg rov qab. | Ceev faj thaum ua, kev tswj qhov kub tsis zoo tuaj yeem ua rau decomposition, corrosion ntawm cov ntsia hlau, thiab cov sij hawm siv khib nyiab tsawg. |
| Qhov ntom | Tsawg ceev (nyob ib ncig ntawm 0.9), tib lub meter, siv cov khoom sib zog. | High ceev (nyob ib ncig ntawm 1.4), kuj yog ib meter ntev, ntau nias ntawm tes. |
Paub txog lawv qhov sib txawv, peb yuav xaiv li cas rau cable lossis tswj cable?
Xaiv TPE rau cov xwm txheej hauv qab no
1. Yog tias koj cov khoom mus rau Tebchaws Europe thiab Amelikas lossis siv los ua cov cuab yeej siv kho mob, cov khoom ua si menyuam yaus, lossis cov khoom siv uas cuam tshuam nrog cov zaub mov, nws yuav tsum yog halogen-dawb thiab ib puag ncig zoo.
2. Thaum siv nyob rau hauv tsheb (tshwj xeeb tshaj yog nyob ze lub cav), cov khoom siv sab nraum zoov thaum lub caij ntuj no, thiab cov cables rau kev cia txias, uas yog, nyob rau hauv cov xwm txheej uas muaj qhov kub thiab txias ntawm ib puag ncig.
3. Nyob rau hauv cov xwm txheej uas cov xov hlau txuas mus tas li, xws li cov neeg hlau, cov hlua khi hlua khi, thiab cov coils feem ntau retracted uas yuav tsum tau rov khoov, TPE muaj kev qaug zog zoo.
4.Yog ua raws li qhov yuav tsum tau ua rau lub ntsej muag me me thiab nyiam kov, xws li siab -kawg lub mloog pob ntseg, cov ntaub ntawv cables, siab - cov khoom siv kawg, thiab lwm yam, TPE kuj tuaj yeem xaiv
Cov xwm txheej hauv qab no tuaj yeem suav tias yog PVC ua cov rwb thaiv tsev lossis sheath ntawm Fais fab cable lossis tswj cable
1.Yog tias koj cov peev nyiaj tsawg thiab koj muaj kev thov siab rau cov xov hlau, koj tuaj yeem xav txog PVC Cable.
2.Yog tias koj muaj kev xav tau siab rau cov nplaim hluav taws xob lossis kev teeb tsa ruaj khov, ces PVC yog qhov kev xaiv zoo, piv txwv li. Nyob rau hauv zoo ventilated kav thiab cable tais.
3.Yog tias koj tau siv PVC ntau xyoo thiab tsis muaj kev tawm tsam thiab tsis tas yuav hloov cov khoom, ces koj tseem tuaj yeem siv PVC.
Lub ntiaj teb ntawm cov ntaub ntawv hloov tshiab txhua hnub, tab sis lub hauv paus ntsiab lus tseem tsis hloov pauv. Kuv vam tias qhov kev sib piv no tuaj yeem dhau los ua cov lus qhia siv tau ntawm koj lub ntsis ntiv tes. Xaiv tsis yog TPE lossis PVC cable nkaus xwb, tab sis kuj xaiv tus khub ntev -.
Sau npe yuav mus rau kuv qhov blog thiab kuv yuav txuas ntxiv qhia txog kev nkag siab zoo ntawm cov ntaub ntawv cable, txheej txheem, thiab kev lag luam tiam sis, vam tias yuav pab koj kom tsis txhob muaj teeb meem thiab txiav txim siab raug.
