Mu gawo lalikulu la zipangizo zopangira caster, TPU, TPE ndi TPR pali zinthu zitatu zomwe zakopa chidwi cha anthu ambiri. Chilichonse chili ndi mawonekedwe apadera ndipo chimagwirizana ndi zochitika zosiyanasiyana zogwiritsidwa ntchito. Kwa ogula zipangizo zopangira caster, ndikofunikira kumvetsetsa mawonekedwe ndi momwe zipangizozi zimagwiritsidwira ntchito.
Zinthu Zopangira TPU
Zipangizo za TPU (thermoplastic polyurethane) zimadziwika ndi kukana kwake kukanda, kukana mafuta, kusinthasintha kwabwino komanso kunyamula katundu. Zipangizozi zimapangitsa kuti TPU caster compound igwiritsidwe ntchito kwambiri m'mawilo ndi ma caster a katundu m'mafakitale ambiri. Kukana kwake kukanda kwambiri kumatanthauza kuti imatha kukhala ndi magwiridwe antchito okhazikika kwa nthawi yayitali, kuchepetsa kuwonongeka kwa magwiridwe antchito chifukwa cha kuwonongeka ndi kusinthasintha kwa nthawi. Kuphatikiza apo, zida za TPU caster zimakhala ndi phokoso likagwira ntchito, koma izi zikuwonetsa kukana kwake bwino komanso kukhazikika. Komabe, ziyenera kudziwika kuti TPU siilimbana ndi hydrolysis, kotero kukhudzana ndi madzi kwa nthawi yayitali kuyenera kupewedwa panthawi yogwiritsa ntchito ndi kusungidwa.
Zipangizo za TPE caster
Chosakaniza cha TPE (thermoplastic elastomer) chimaphatikiza kusinthasintha kwakukulu, mphamvu ndi kulimba kwa mphira ndi mawonekedwe a jekeseni. Izi zimapangitsa kuti ma TPE caster akhale osinthasintha komanso ogwira ntchito bwino popanga zinthu. Kuphatikiza apo, ma TPE caster ndi abwino kwa chilengedwe komanso osawononga chilengedwe, okhala ndi utoto wabwino kwambiri, kukhudza kofewa, kukana nyengo, kukana kutopa komanso kukana kutentha. Makhalidwe amenewa amapangitsa kuti zinthu za TPE caster zigwiritsidwe ntchito kwambiri m'mafakitale monga mawilo a katundu ndi mawilo a trolley. Kukana kwake kukanda pang'ono, kusinthasintha kwake komanso kuyamwa kwa mantha kumapangitsa kuti zinthu za TPE caster zigwire bwino ntchito zikakumana ndi katundu wolemera komanso kugundana. Nthawi yomweyo, phokoso lochepa la zinthu za TPE caster zimapangitsa kuti zikhale zinthu zomwe zimakondedwa kwambiri kuti zikhale pamalo chete. Kuphatikiza apo, zinthu za TPE caster zitha kukulungidwa ndikulumikizidwa ndi PP, PE, PC, PS, ABS ndi zinthu zina zoyambira, kukulitsa malo ake ogwiritsira ntchito.
Zinthu Zopangira TPR Caster
Chomera cha TPR (thermoplastic raber) chimaonedwa ngati mtundu wa TPE (mu gawo la polystyrene elastomer). Chimachokera ku SBS ndipo chili ndi kusinthasintha bwino kuposa TPE, koma sichimamva kupweteka pang'ono kuposa TPE; komabe, chomera cha TPR chili ndi mphamvu zabwino kwambiri zotsutsana ndi kupsinjika, kusinthasintha, komanso kuyamwa kwa shock-absorption, zomwe zimapangitsa kuti chigwiritsidwe ntchito ngati chomera champhamvu chomwe chimakhudzidwa ndi katundu wolemera komanso kugundana. Kuphatikiza apo, chomera cha TPR ndi chotsika mtengo kuposa TPE, zomwe zimapatsa mwayi pazachuma. Mofanana ndi TPE, zinthu za TPR zomera zimathanso kupangidwa ndi mapulasitiki olimba monga PA ndi PP, zomwe zimapangitsa kuti ntchito yake ikhale yosinthasintha.
Chidule
Zipangizo zopopera za TPU, TPE ndi TPR chilichonse chili ndi makhalidwe akeake komanso ntchito zake zapadera. TPU imadziwika ndi kukana kwake kukanda, kukana mafuta komanso mphamvu zonyamula katundu; TPE imakondedwa chifukwa cha kusinthasintha kwake, mphamvu zake zambiri komanso kuthekera kwake kopanga jakisoni; TPR ili ndi malo m'munda wa zopopera zolemera chifukwa cha kusinthasintha kwake komanso mtengo wake wotsika. Posankha zipangizo zopopera izi, tiyenera kuweruza malinga ndi momwe zinthu zomwe zagwiritsidwa ntchito komanso zosowa zake kuti tiwonetsetse kuti zipangizo zomwe zasankhidwa zitha kukwaniritsa zosowa zathu.
