Lub superiority ntawm polyurethane stems los ntawm nws cov cim tshwj xeeb ntawm cov khoom siv lub cev, uas ua tiav ua tiav cov khoom siv cov ntsiab lus niaj hnub: qhov kev ua tau zoo tshaj plaws, meej, thiab kev ntseeg tau.
1. Tshwj xeeb hnav tsis kam
Ib ntawm Polyurethane tus qauv loj tshaj plaws yog nws cov lus pom zoo rau kev puas tsuaj. Nws muaj cov coeffinally tsis muaj kev sib txhuam thiab ib qho tshwj xeeb resilient saum npoo, zoo countering cov khoom poob tshwm sim los ntawm kev sib txhuam nrog pulleys. Qhov no ncaj qha txhais tau tias lub neej pabcuam ntxiv, tshwj xeeb hauv kev ua haujlwm siab, nquag pib}}} nres tsheb. Xws li durabilivly txo qis downtime thiab tu nqi.
2. Lub zog siab thiab kua muag
Polyurethane unquamely txuas hniav qhov sib txawv ntawm roj hmab tus elasticity elasticity thiab yas 'tochaning. Nws cov qauv molecular xaus cov khoom siv siab tensile lub zog, ua kom nws tau txais kev rub tawm ntau dua los kua muag. Qhov no txhais tau tias polyurethane txoj siv sia tuaj yeem ua rau muaj kev cuam tshuam siab ruaj khov thiab cuam tshuam tam sim ntawd tsis muaj ntev dhau los yog lov tau. Lub zog no tseem tso cai rau cov tuam txhab tsim tawm los tsim thinner, siv lub zog piv rau lossis txawm tias muaj cov roj hmab loj dua, ua kom cov tsav tsheb loj dua.
3. Tshwj xeeb tsis kam rau roj, roj thiab tshuaj lom neeg
Ntau cov kev lag luam thiab tsheb tsheb ib puag ncig koom nrog rau cov kua roj ua kom zoo, cov kua dej hydraulic thiab ozone paug. Cov roj hmab roj hmab swells swased, softens thiab degrades thaum chwv nrog cov tshuaj no. Polyurethane, txawm li cas los xij, cov khoom pov thawj ua tau zoo tshaj rau ntau haiv neeg roj thiab tshuaj lom neeg. Qhov no ua rau polyurethane koj txoj kev coj zoo rau cov ntawv thov xav tau xws li cov khoom siv cav tsheb, cov khoom noj ua zaub mov (khoom siv tu) thiab tshuab luam ntawv. Lub siv tsav tsav tswj cov qauv txheej txheem kev ntseeg thiab seem ruaj khov, ua kom pom kev zoo sib xws uas lwm cov khoom poob.
4. Precision Moulding thiab seem ruaj khov
Polyurethane feem ntau yog tsim los ntawm kev nrum lossis machining, ua rau cov khoom siv ncaj ncees thiab cov hlua khi (rau ntau {{ribbed siv tawv). Nws cov khoom siv hysteresis tsawg uas txhais tau tias qis dua kub nce nyob rau hauv cov khoom siv roj hmab piv rau qee cov ntaub ntawv roj hmab. Qhov precision no yog qhov tseem ceeb rau cov kis tau sib txawv, qhov twg ib tus hniav profile sib txawv tuaj yeem ua rau ncua sij hawm ua kom tiav, kev co, thiab suab nrov. Discensional stability kom txoj siv sia tswj kom muaj ntev thiab contour nyob rau lub sijhawm, lav tau cov kev sib tw nrawm nrawm thiab muaj zog sib kis tau zoo.
5. Kev hloov pauv zoo tshaj plaws thiab nkees tsis kam
Polyurethane tswj hwm siab elasticity thiab kuj mus rau flexural rog thaum khaws lub zog. Nws rov qab los ntawm kev rov ua dua tshiab thiab ncab yam tsis muaj kev sib nraus tas mus li. Cov cuab yeej no tseem ceeb rau cov ntawv thov uas muaj me me- txoj siv sia ntawm lub neej, ua kom muaj kev ntxhov siab ntev.
Ntsuas Qhov Siab: Kev Txiav Txim Siab
Tsis muaj khoom siv yog thoob ntiaj teb zoo tag nrho. Polyurethane raw cov khoom siv feem ntau tau tshaj li cov qauv ntawm neoprene. Thaum nws tau ntsuas qhov kub txuas ntxiv ua tau raws li feem ntau cov ntawv thov, nws yuav poob luv luv rau qee qhov siab tshwj xeeb- rewbers. Qee lub polyester - Raws polyurethanes muaj kev cuam tshuam hydradation (noo {5} saws pu yog saws dav rau nws cov headly hydrolysis tsis kam.
Txawm hais tias tus nqi siab dua, polyurethane muab tag nrho tus nqi {{0} Txoj kev ua haujlwm kom zoo, thiab txhim khu kev qha, ua haujlwm meej meej hauv kev xav tau. Thaum cov ntawv thov txuas ntxiv dhau ntawm cov khoom siv fais fab yooj yim {2} {polyurethane {} Cov khoom siv huv si ua nws cov khoom siv tsis zoo, thiab cov yam ntxwv ua kom zoo dua qub ua rau nws tsis muaj peev xwm ntawm kev xaiv.
