Ob lub ntsiab ntawm cov tawv nqaij sab nrauv rau cov hlua khi ntawm lub khw yog PVC thiab PUR. Muaj qhov sib txawv tseem ceeb hauv lawv qhov kev ua tau zoo. Tshwj xeeb tshaj yog rau cov khoom siv uas yuav tsum tau rov ua dua thiab sib cog lus txhua hnub, xaiv cov khoom siv tsis raug yuav ua ob npaug rau tus nqi ntev. Cia peb qhia qhov txawv ntawm lawv. Tom qab nyeem qhov no, koj yuav tsis ua yuam kev thaum xaiv.
1. Resilience txawv
PVC caij nplooj ntoos hlav cable
PVC ua tiav softness los ntawm kev siv cov yas yas. Tom qab rov ua dua ib lub sijhawm ntev, cov yas yas sab hauv maj mam tawm thiab poob lawv cov txiaj ntsig, ua rau txo qis elasticity. Lub retraction ceev tom qab stretching yog qeeb heev, thiab caij nplooj ntoos hlav coils feem ntau tsis retract kiag li, lub cable yuav xoob thiab poob. Tom qab qee lub sijhawm ntawm kev siv, qhov sib txawv ntawm cov coils nce, thiab cov xaim yuav ntxhov thiab tangled. Kev txhim kho PVC kev ua tau zoo yuav ua kom zoo dua qub, thiab tus nqi raw khoom yog ntau dua 30% qis dua PUR.
PUR polyurethane caij nplooj ntoos hlav cable
PUR inherently muaj ib tug siab elastic molecular qauv. Thaum ncab thiab tso tawm, nws cia li rebounds. Cov coils yog nruj thiab tsis deform. Nws tuaj yeem ncav cuag 3-4 npaug ntawm nws qhov qub ntev. Tom qab tsheej lab ntawm kev nthuav dav thiab kev sib cog lus, nws tseem tuav ruaj khov rov qab los. Nyob rau lub sijhawm ntev ntawm kev siv, cov coils yuav tsis xoob lossis elongated thiab deformed. Cov xaim tseem nyob zoo thiab ua kom zoo txawm tias cov cuab yeej txav mus los.
2. Hnav Resistance thiab Tensile Life
Cov khoom siv ntawm PVC sab nrauv yog nkig thiab muaj kev hnav tsis zoo. Txawm tias muaj kev sib txhuam me ntsis nrog cov khoom siv lossis hauv av tuaj yeem ua rau nws khawb thiab tig dawb. Tom qab nquag rub thiab khoov, cov kab nrib pleb zoo tshwm rau saum npoo ntawm lub hau tiv thaiv, uas maj mam txuas mus rau sab hauv thiab nws thiaj li hnav los ntawm txheej rwb thaiv tsev, nthuav tawm cov tooj liab thiab ua rau luv luv. Tus qauv ntsuas tsuas tuaj yeem tiv taus ntau txhiab tus khoov. Nrog nquag siv los ntawm cov cuab yeej siv hluav taws xob thiab cov cuab yeej tuav, lub neej yuav luv dua.
PUR cov tawv nqaij sab nrauv tau lees paub hauv kev lag luam raws li cov khoom hnav zoo heev - cov khoom tiv taus. Nws hnav tsis kam yog 3-5 npaug ntawm PVC, thiab nws muaj zog tiv thaiv- tsim kua muag thiab tiv thaiv khawb. Nws tsis yooj yim puas los ntawm kev sib txhuam los ntawm cov pob zeb crushed nyob rau hauv lub rhiav, hlau npoo thiab cov ces kaum, los yog dragging rov qab. Nws tuaj yeem tiv taus ntau lab ntawm kev rov nthuav dav thiab kev cog lus. Raws li tib lub sijhawm, nws lub neej kev pabcuam yog 2-3 npaug ntawm PVC cables, txo cov nqi zog thiab cov khoom siv los hloov cov cables.
3.Oil kuj thiab ib puag ncig adaptability
Qhov tsis zoo ntawm PVC yog qhov tseem ceeb. Nws tsis tiv taus cov roj cav, txiav kua, thiab roj lubricating. Ntev - lub sij hawm raug rau cov roj stains yuav ua rau cov txheej txheej sab nrauv o, soften thiab ua nplaum, ua rau kev laus thiab tawg; nyob rau hauv qis- qhov kub thiab txias ib puag ncig (hauv qab -5 degree), nws yuav nyuaj thiab nkig ncaj qha; ntev -lub sij hawm sab nraum zoov raug tshav ntuj yog qhov ua rau cov laus thiab hmoov, thiab nws tsuas yog haum rau qhuav, ib txwm - kub, thiab tsis muaj roj-dawb sab hauv tsev cov khoom yooj yim.
PUR yog qhov hloov tau zoo rau kev ua haujlwm hnyav. Nws yog resistant rau roj cav, coolant, thiab ntau yam qaug zog acid thiab alkali hnyav. Ntev- siv sijhawm ntev hauv cov roj- stained Rhiav yuav tsis ua kom nthuav dav thiab tsis zoo; Qhov ntsuas kub yog -40℃txog 80℃. Nyob rau sab qaum teb qis- qhov chaw ua haujlwm kub thiab cov khoom siv sab nraum zoov, nws tseem mos nyob rau lub caij ntuj no; nws tau tsim- hauv kev tiv thaiv- kev ua haujlwm ntawm ultraviolet, thiab nws tsis yooj yim rau kev laus thaum siv sab nraum zoov ntev. Nws kuj tseem tsis yooj yim rau cov dej tawg hauv qhov chaw ntub dej thiab cov dej uas muaj dej.
4. Kev sib piv ntawm qis -kub kev ua haujlwm
PVC: Tom qab qhov kub thiab txias, nws hardness ho nce. Nyob rau lub caij ntuj no, rov nthuav dav thiab contraction yuav ua rau cov txheej txheej sab nrauv tawg.
PUR: Nws tuav softness thiab toughness ntawm qis kub. Nws yuav tsis tawg txawm tias thaum khoov lossis ncab ntawm rho tawm 30 txog 40 degrees Celsius. Nws raug nquahu kom siv rau hauv cov khoom siv tub yees thiab cov khoom siv txawb sab nraum zoov nyob rau sab qaum teb.
5. Tus nqi thiab kev hloov kho rau cov xwm txheej
PVC caij nplooj ntoos hlav cables haum rau cov xwm txheej no
Cov khoom siv me me hauv tsev, nrog ob peb ncab thiab sib cog lus ib hnub, tsawg- siv zaus;
Qhuav, plua plav-dawb, roj-dawb, thiab nyob rau hauv chav tsev kub ib puag ncig;
Tsawg- cov khoom siv yooj yim raug nqi, cov kab sib txuas ib ntus, nrog cov kev xav tau qis rau lub neej ua haujlwm.
Qhov zoo: Tus nqi qis, tus nqi - siv tau rau luv luv - siv sijhawm.
PUR caij nplooj ntoos hlav cable yuav tsum teb
Muaj cov cuab yeej siv hluav taws xob, cov cuab yeej siv hluav taws xob, lub xov tooj ntawm tes, cov cuab yeej tshawb nrhiav tuav, ntau lub sij hawm ntawm reciprocating stretching ib feeb;
Machining khoom, vuam khoom, siv tshuab, kev cob qhia nrog ntau cov roj stains;
Cov khoom siv sab nraum zoov, lub caij ntuj no qis- qhov kub thiab txias ib puag ncig, lub teeb txawb sab nraum zoov;
Cov cuab yeej siv yuav tsum tau ua haujlwm ruaj khov rau lub sijhawm ntev thiab tsis xav kom nquag hloov cov cables lossis nres rau kev saib xyuas.
Qhov tsis zoo: Tus nqi yuav khoom siab dua PVC, tab sis xav txog tag nrho cov kev pab cuam lub neej thiab cov nqi tu, nws yog tus nqi ntau dua - zoo.
