Styrene siv rau dab tsi?
Styrene yog ib qho khoom siv hluavtaws uas hloov tau thiab nws yog siv rau hauv kev tsim cov ntaub ntawv uas tau siv los tsim ntau yam khoom zoo nkauj thoob plaws ntau yam kev lag luam.Qhov zoo tshaj plaws ntawm cov khoom siv styrene-based yog polystyrene, nrog ze li 65% ntawm tag nrho cov styrene siv los tsim qhov no.Polystyrene yog siv rau hauv ntau yam khoom siv niaj hnub thiab tuaj yeem pom hauv ntim khoom, cov khoom ua si, cov khoom siv ua si, cov khoom siv hluav taws xob thiab cov kaus mom kev nyab xeeb, rau npe tab sis ob peb tug.
Lwm cov ntaub ntawv tsim muaj xws li acrylonitrile-butadiene styrene (ABS) thiab styrene-acrylonitrile (SAN) resins thiab suav txog kwv yees li 16% ntawm kev noj styrene.ABS yog cov khoom siv thermoplastic uas siv rau hauv kev lag luam tsheb thiab hluav taws xob, thaum SAN yog cov yas co-polymer uas siv rau hauv ntau yam khoom siv, ntim khoom, thiab kev siv tsheb.
Styrene kuj tseem siv rau hauv kev tsim cov styrene-butadiene roj hmab (SBR) elastomers thiab latexes, thiab suav txog kwv yees li 6% ntawm kev noj.SBR yog siv rau hauv cov log tsheb, thiab cov hlua khi thiab cov hoses rau cov tshuab, nrog rau cov khoom siv hauv tsev xws li cov khoom ua si, daim txhuam cev thiab cov vuas hauv pem teb.
Unsaturated polyester resin (UPR), zoo dua lub npe hu ua fiberglass, yog lwm cov khoom siv raws li styrene thiab qhov no kuj suav txog kwv yees li 6% ntawm styrene noj.
Keeb kwm, kev loj hlob ntawm kev siv styrene tau zoo txawm hais tias qhov kev loj hlob no tau qeeb nrog kev lag luam thoob ntiaj teb poob qis.
