Hauv kev tsim khoom lag luam, tsheb sab hauv, thiab cov khoom siv ua lag luam, cov khoom yas feem ntau raug rau ntau yam tshuaj, suav nrog cov roj tshuab, roj, tshuaj ntxuav tes txhua hnub, thiab cawv- cov tshuaj tua kab mob. Tshuaj tiv thaiv tiv thaiv cov roj stains thiab tshuaj ntxuav yog ib qho tseem ceeb qhia uas txiav txim siab lub neej kev pab cuam thiab nto stability ntawm cov khoom yas. Ntawm cov khoom siv hluav taws xob ntau tshaj plaws HIPS, ABS, thiab TPU, lawv qhov kev tiv thaiv rau cov roj thiab cov tshuaj ntxuav tau sib txawv heev, coj cov kev xaiv cov khoom siv rau cov xwm txheej sib txawv.
TPU (Thermoplastic Polyurethane) sawv tawm raws li tuszoo tshaj - cov khoom sivnyob rau hauv tag nrho cov tshuaj tiv thaiv. With a dense molecular structure, TPU exhibits excellent tolerance to mineral oil, lubricating grease, and industrial oil. Nws yuav tsis o, tig nplaum, los yog raug kev kis kab mob mus tas li tom qab ntev -lub sij hawm sib cuag roj. Lub caij no, nws tiv taus yaig los ntawm nruab nrab thiab tsis muaj zog alkaline ntxuav, nrog rau cov tshuaj tua kab mob cawv. Tsis muaj qhov chaw ntxuav hniav dawb, tawg, lossis gloss poob tshwm sim tom qab ntxuav tas li. Qhov tsuas yog drawbacks yog nws cov tsis tshua muaj rigidity thiab tus nqi siab dua. Vim li no, TPU feem ntau yog siv los ua cov txheej txheem sib xyaw ua ke es tsis yog cov khoom siv sib luag kom sib npaug ntawm cov khoom siv thiab cov nqi.
ABS nyob rau hauv nruab nrab ntawm cov tshuaj tiv thaiv. General-qib ABS tuaj yeem tiv taus luv luv-lub sij hawm tiv tauj nrog cov tshuaj ntxuav tes me me yam tsis muaj kev puas tsuaj. Txawm li cas los xij, nws yog qhov yooj yim rau kev ntxhov siab tawg, ua rau lub ntsej muag tsis zoo, thiab ua kom tsis muaj xim thaum raug cov tshuaj alkaline muaj zog, siab -cov tshuaj cawv cawv, thiab cov roj ntxhia. Qhov seem sab hauv kev ntxhov siab los ntawm molding yuav ua rau cov khoom laus thiab tawg tsim thaum rov ua dua. Hloov kho tshuaj lom neeg- tiv taus ABS tuaj yeem txhim kho qhov tsis xws luag, ua rau tus nqi- xaiv tau zoo rau cov khoom siv sib xyaw nrog cov kev xav tau ntawm kev tu me ntsis.
HIPS (High-Impact Polystyrene) muaj covphem tshuaj tiv thaivntawm peb cov ntaub ntawv. Nws cov qauv molecular yog rhiab heev rau cov kuab tshuaj organic thiab ntxhia roj. Ntev -lub sij hawm sib cuag nrog cov roj stains yuav ua rau pom tseeb nyiaj streaks, tawg, thiab cov khoom degradation. Kev so tsis tu ncua nrog cawv lossis cov tshuaj ntxuav kom muaj zog yuav ua rau lub ntsej muag puas tsuaj, ua rau gloss attenuation, hmoov, thiab kev puas tsuaj mus tas li. HIPS tsuas yog tsim nyog rau tsawg- cov xwm txheej tu vaj tse uas tsis muaj roj paug thiab ntxuav.
Piv txwv li, cov tshuaj tiv thaiv qib tiv thaiv cov roj thiab cov tshuaj ntxuav yog:TPU> Hloov ABS> General ABS> HIPS. Rau siab -xav tau scenarios xav tau kev tu thiab roj tsis tu ncua, TPU cov ntaub ntawv sib xyaw yog cov tshuaj zoo tshaj. Rau cov khoom siv sib xyaw ua ke nrog cov nqi txwv, hloov ABS yog txhim khu kev qha. HIPS raug pom zoo tsuas yog rau cov uas tsis yog- raug, qis- cov pa phem. Qhov kev sib txuam no yog dav siv nyob rau hauv automotive interiors, coj mus muag khoom, thiab industrial accessory manufacturing.
