Nkag siab txog cov khoom sib txawv ntawm Kev Tiv Thaiv Tsheb Xim Xim

Xim tiv thaiv zaj duab xisyog xim tsis muaj xim thiab pob tshab, tsis cuam tshuam rau kev zoo nkauj ntawm lub tsheb lub cev xim, thiab muaj lub zog hardness thiab zoo saj zawg zog, txawm tias siv cov yuam sij thiab lwm yam khoom nyuaj rau ntawm qhov chaw ntawm nws qhov kev sib txhuam rov qab yuav tsis tawm ib yam dab tsi.

Nws muaj kev ua haujlwm ntawm kev tiv thaiv ultraviolet irradiation thiab tiv thaiv cov ntawv hlau los ntawm xeb.

Tiv thaiv los nag thiab acidic corrosion, tiv thaiv txhua qhov chaw ntawm lub tsheb lub cev pleev xim nto los ntawm tev thiab khawb, thiab tiv thaiv cov xim pleev xim los ntawm xeb thiab laus daj. Tam sim no nyob rau hauv kev ua lag luam kom ua tau ib lub koob npe nrov, lub tsheb zaj duab xis hom muaj US puag, zaj zaj duab xis, 3M, Weigu, thiab lwm yam., pheej yig, nqi-zoo yogTianrun PPF, lub npe qub yog kev ntseeg siab.

Yog li, lub cev tiv thaiv zaj duab xis ua li cas los tiv thaiv lub cev? Dab tsi yog qhov muaj pes tsawg leeg ntawm nws cov khoom?

Ua tau

Polyurethane khoom, los yog polyurethane (Polyurethane), los yog PU, yog ib tug tshiab organic polymer cov ntaub ntawv hu ua "thib tsib loj yas." Thawj tiam ntawm cov xim tiv thaiv zaj duab xis yog ua los ntawm cov khoom PU. Nws tau pib siv hauv tub rog los tiv thaiv dav hlau, nkoj, thiab lwm yam. Hauv xyoo 2004, nws tau maj mam siv rau pej xeem siv. PU cov khoom, txawm tias lub cev muaj zog ntawm lub suab, muaj zog toughness, softness, thiab zoo tensile lub zog, vim nws tsis zoo huab cua tsis kam, tsis muaj peev xwm tiv taus alkaline corrosion, thiab yellowing yooj yim heev, raug tshem tawm sai sai ntawm lub khw.

PVC

Txawm hais tias PU tau raug tshem tawm los ntawm kev ua lag luam, tib neeg kev mloog rau cov xim tsheb tseem tsis tau tshem tawm PU, thiab lub cim thib ob ntawm cov xim tiv thaiv zaj duab xis, PVC, tau los ua. PVC yog ib lub ntiaj teb loj tshaj plaws tsim cov khoom yas; Nws yog lub npe tag nrho ntawm polyvinyl chloride, lub ntsiab ntawm polyvinyl chloride. Cov khoom siv PVC yog qhov nyuaj dua, muaj kev cuam tshuam tsis zoo, thiab tus nqi qis dua. Txawm li cas los xij, vim tias qhov ncab thiab hloov pauv ntawm qhov tsis muaj zog, peb tsis tuaj yeem paub qhov zoo meej ntug nyhuv hauv cov txheej txheem mounting tiag tiag. Tib lub sijhawm, kev pabcuam lub neej ntawm cov khoom siv PVC yog luv luv; Tom qab ib lub sij hawm, yuav muaj yellowing, staining, cracking, thiab lwm yam. Txawm hais tias PVC muaj ib tug tej yam degree ntawm nplaim retardancy, nws thermal stability tsis zoo, thiab kub kub yuav ua rau decomposition, yog li tso hydrogen chloride thiab lwm yam tshuaj lom gases, ua rau tib neeg lub cev thiab ib puag ncig muaj kev phom sij.

TPU

Tib neeg cov kev tiv thaiv ntawm thawj lub tsheb xim, tab sis kuj xyuam xim rau kev nyab xeeb ntawm ib puag ncig; peb tiam ntawm cov xim tiv thaiv zaj duab xis, TPU, tau yug los; TPU tseem hu ua thermoplastic polyurethane, lub npe tag nrho ntawm ThermoplasticPolyrethanes. TPU yog ua tiav raws li PU los muab kev tiv thaiv zoo dua, tiv thaiv av, yoog raws, thiab kev ua haujlwm ntawm tus kheej. Nyob rau tib lub sijhawm, TPU yog cov khoom lag luam paub tab, tus phooj ywg zoo ib puag ncig uas tsis ua phem rau ib puag ncig. Txawm li cas los xij, tom qab muaj ntau yam zoo, nws tus nqi yuav siab dua tus nqi ntawm thawj ob tiam ntawm cov xim tiv thaiv zaj duab xis.TPHTPH yog ib yam khoom uas tawm los ntawm qhov tsis muaj nyob hauv ob xyoos dhau los. Lub npe hu ua TPH tuaj yeem muab piv rau TPU, uas yog qhov tseem ceeb tseem ceeb ntawm cov khoom siv PVC, tsuas yog ntxiv cov yas yas, kom cov khoom siv PVC ua softer thiab kev tsim kho yog ncaj nraim li cov khoom siv PVC. Txawm li cas los xij, plasticizers kuj tseem muaj nyob kom cov khoom lag luam sai sai, thiab tom qab lub sijhawm ntev, yuav tawg. Tsis tas li ntawd, cov nplaum txheej ntawm TPH cov khoom lag luam poob sai sai, ua cov nplaum nplaum lossis cov nplaum nplaum rau ntawm cov xim pleev xim, cuam tshuam rau kev tsim kho.
