Dab tsi tseem ceeb yuav tsum tau them sai sai rau thaum kev ua cov hnab loj ntawm polyurethane txheej txheej?
Ntau tus phooj ywg uas xav tuaj tham txog cov ncauj lus no yuav hnov xeb heev, tab sis hauv cov ntawv thov tshwj xeeb, nws yog qhov tseeb feem ntau hnov ib tus, thiab nws yuav tsum tsis yooj yim kom xeb. Zoo, txij li thaum lub tshuab polyurethane txheej txheem thev naus laus zis ua kom muaj zog, nws kuj yog li tsis raug rau cov neeg thiab cov neeg siv khoom. Nws' s kheej. Niaj hnub no, cov neeg nyob hauv Henan Xeev tuaj yeem tham txog ib qho tab sis tsis zoo txog kev siv tshuab thev naus laus zis. , Puas yog polyurethane txheej txheem thev naus laus zis ntawm lub hnab loj.
1. Cov ntaub phom Polyurethane, tsis yog txhua lub hnab ntim yuav tsum yog cov khoom siv polyurethane. Polyurethane txheej tsuas yog siv tau hauv cov qauv ntim uas yuav tsum yog cov dej noo-pov thawj thiab cov khoom muaj sia tiag tiag los ua kom lawv muaj cov dej noo noo-pov thawj thiab ua haujlwm rau dej.
2. Cov ntaub ntawv txheej txheem polyurethane tsis siv rau ob qho khoom ua si pp thiab pe, pp yog tiag tiag tsis tuaj yeem siv, tsuas yog pe siv tau. Feem ntau ntawm polyurethane coatings uas tib neeg feem ntau pom yog tag nrho cov pe polyurethane co. Cov.
3. Qhov hnyav ntawm tuj lub hnab ntawm polyurethane txheej tsis yog qhov loj dua qhov ua tau zoo, thiab sib dua nws tsis zoo dua. Yuav tsum muab faib raws li nws tus kheej qhov kev mob tshwj xeeb.
Dab tsi yog lub hauv paus ua rau lub wrinkles ntawm lub hnab tuj ntawm lub kaum sab sauv txoj siv menyuam?
Qee lub sij hawm tib neeg tsuas yog ua lub hnab loj ntawm cov khoom, thiab muaj ntau yam tawv qhwv ntawm qhov chaw. Qhov tseeb, lub laj thawj tseem ceeb rau qhov xwm txheej no yog tias nws tshwm sim hauv tag nrho cov txheej txheem ntawm lub raj raj. Cov neeg hauv Henan Xeev txog tam sim no Ua kev tshawb fawb ntxaws ntawm qhov teeb meem no. Nyob rau hauv cov nyhuv ntawm qhov dav kho cov pas nrig ntawm lub stent, daim ntaub nruas ncab mus rau hauv lub raj ncaj, thiab ob sab thiab ib puag ncig ntawm lub raj ncaj yog kev sib txhuam nrog qhov dav kho qws. Yog tias ib sab ntawm qhov dav dav kho cov qws tsis sib raug zoo nrog cov khoom siv raj, hauv qab qhov kev ua ntawm cov menyuam sab saud kom nce lub zog, muaj kev sib txhuam ntawm ob sab thiab sab nraud, uas yuav ua rau cov khoom siv raj ntawm ob sab. thiab lwm sab kom raug hloov nyob rau hauv cov kev cai ntawm ductility. Sab uas tsis kov tus pas nrig kho yog ntev, thiab tsis muaj kev sib txhuam los yog txhuam me me nyob hauv nruab nrab txoj hauj lwm, yog li ntawd cov cuab yeej siv cov raj hauv qhov nruab nrab tsis tau ntev lossis tsis ntev. Hauv txoj kev ntawd, nws zoo nkaus li cov khoom siv raj xa los ntawm cov coj qhia yog qhov zoo ib yam, tab sis cov khoom siv raj tau tsa rau ob sab thiab sab nraud yog cov khoom siv raj ntev dua yam tsis tau kov cov nthuav tawm, thiab qhov nruab nrab ntev yuav tsawg dua. Tom qab lub nra ntawm cov menyuam tau dhau, tsis muaj kev tsav tsheb, thiab lub zog tsis siv zog muaj ntau qhov sib zog ntau dua li lub zog nqus. Cov khoom siv lub raj nrog ntev ductility ntawm ob sab thiab sab nraud sib sau ntau dua, tab sis tsis chwv qhov hloov kho dav. Sab uas kov cov khoom siv lub raj xa khoom yog qhov sib sau tsawg dua, kom ob sab thiab sab nraud ua nruj nreem, thiab sab uas tsis kov qhov dav hloov kho cov pas nrig yog xoob hauv nruab nrab. Tus nqi ntawm cov nplais ua ib cov hle convex raws li txoj hlua sib tw sab saud. Thaum tus nqi ntawm kev sib nraus nce mus txog ib qho nqi, nws yuav raug nias tawm thiab rhuav tshem.
