Cov xim tiv thaiv zaj duab xis yog siv los tiv thaiv khawb thiab khawb, tiv thaiv cov xim ntawm lub tsheb qub, thiab tib lub sijhawm txhim kho qhov ci ntawm lub tsheb xim. Tshwj tsis yog nws yog" kev puas tsuaj" khawb tawm tag nrho lub tsheb, qhov tseem ceeb tag nrho cov khawb me me uas yuav raug ntsib hauv lub neej niaj hnub tuaj yeem kho tau. Tam sim no, xim tiv thaiv zaj duab xis mas muaj plaub yam khoom, cia's kawm txog nws ua ke.
1. Cov khoom siv PU
Cov khoom siv polyurethane, tseem hu ua Polyurethane, lossis PU luv luv, yog cov khoom siv organic polymer thiab hu ua" thib tsib-loj tshaj yas". Thawj tiam xim tiv thaiv zaj duab xis yog ua los ntawm PU cov ntaub ntawv, uas yog thawj zaug siv nyob rau hauv cov tub rog teb thiab maj mam siv rau pej xeem siv nyob rau hauv lub xyoo pua 21st.
Qhov zoo ntawm cov khoom siv PU yog qhov muaj zog toughness, softness, thiab siab tensile lub zog, tab sis qhov tsis zoo kuj tseem pom tseeb, xws li huab cua tsis zoo thiab tsis muaj zog tiv thaiv cov tshuaj alkaline. Niaj hnub no, PU tiv thaiv zaj duab xis tsis tshua pom hauv khw.
2. Cov khoom siv PVC
Qhov thib ob tiam xim tiv thaiv zaj duab xis yog ua los ntawm PVC, thiab lub ntsiab tivthaiv yog polyvinyl chloride. Qhov zoo ntawm PVC yog cov khoom siv nyuaj, muaj zog tiv thaiv, thiab tus nqi qis dua. Tau kawg, muaj qee qhov tsis txaus, xws li tsis muaj zog stretchability thiab yooj, kev pab cuam lub neej luv luv, thiab lwm yam. Tsis tas li ntawd, qhov thermal stability tsis zoo, thiab kub siab rau lub sijhawm ntev yuav ua rau decomposition, yog li tso tawm hydrogen chloride thiab lwm yam pa phem.
3. Cov khoom siv TPU
Thib peb-tiam xim tiv thaiv zaj duab xis TPU, tseem hu ua thermoplastic polyurethane, yog ua tiav raws li PU. Nws muaj kev tiv thaiv zoo dua, tiv thaiv av, ductility, thiab kev ua haujlwm ntawm tus kheej.
Nyob rau tib lub sijhawm, kev ua haujlwm ib puag ncig ntawm TPU kuj tseem zoo thiab piv nrog cov khoom siv PVC, tsis muaj kuab paug rau ib puag ncig. Tau kawg, qhov tsis zoo yog tias tus nqi thiab tus nqi siab dua.
4. Cov khoom siv TPH
TPH yog ib yam khoom tshiab uas tau tawm hauv ob xyoos dhau los. Nws yog ib qho tseem ceeb ntawm cov khoom siv PVC, tab sis nrog kev sib ntxiv ntawm cov yas yas, cov khoom qub PVC yog softened, ua rau kev tsim kho yooj yim dua thiab ua haujlwm zoo dua. Tau kawg, muaj qhov zoo thiab qhov tsis zoo. Tom qab ntxiv cov yas yas, cov khoom yuav nkig los yog tawg. Tsis tas li ntawd, cov nplaum txheej ntawm TPH cov khoom yog ib qho yooj yim kom poob tawm, thiab nws tseem yuav tsim offset luam ntawv los yog kua nplaum seem ntawm cov xim nto, uas tseem cuam tshuam rau kev tsim kho.
Hauv cov ntsiab lus, ntawm plaub cov ntaub ntawv saum toj no, TPU thermoplastic polyurethane yog tam sim no qhov zoo tshaj plaws painting nto tiv thaiv zaj duab xis ntawm lub khw. Piv nrog PU, nws muaj ib qho kev kho cua sov ntxiv, thiab muaj zog thiab tiv thaiv kev laus, thiab khawb tau. Kho, thiab nws puas tseem yog cov khoom siv tiv thaiv ib puag ncig, yog qhov pom zoo tshaj plaws.
