Roj Hmab thiab Cov Khoom Siv Yas yog qhov tsis tseem ceeb hauv kev lag luam niaj hnub thiab lub neej txhua hnub. Lawv cov txheej txheem synthesis ncaj qha cuam tshuam rau lawv cov kev ua tau zoo thiab kev ua ntawv thov ntau. Roj hmab thiab cov khoom yas yog feem ntau cov cermanized rau hauv ob pawg loj: roj hmab thiab yas. Thaum lawv cov txheej txheem synthesis sib txawv, ob qho tib si koom nrog tshuaj synthesis thiab kev ua lub cev ntawm cov khoom siv polymer.
Roj hmab hluavtaws feem ntau yog siv petrochemical raw cov ntaub ntawv, tsim roj hmab raw roj hmab los ntawm polymnerization kev tawm tsam. Cov roj hmab ntuj tau muab los ntawm cov kua txiv hmab roj hmab ntoo, thaum cov khoom siv hluavtaws xws li roj hmab roj hmab (pob roj hmab} butadiene Piv txwv li, emulsion polymerization ntawm butadiene thiab styrene nyob rau hauv lub xub ntiag ntawm cov emulsifier tsim sbr, roj hmab nrog elasticity. Cov khoom siv roj hmab tso tawm hauv cov roj hmab vulcanization, tus txheej txheem uas nws nyiam nrog cov qauv siv hluav taws xob xws li cov roj hmab muaj zog thiab ua kom muaj zog.
Yas Entthesis feem ntau yog kev sib haum xeeb ntawm polyaddition lossis polycondensation cov kev cuam tshuam. Thermoplastics xws li polyethylene (PE) thiab polypropylene (PP) yog tsim los ntawm polymerization ntawm ethylene thiab propylene monomers. Lawv cov hlua molecular yog pub dawb ntawm cov tshuaj lom neeg hla dej, tso cai rau lawv kom rov ua kom sov dua thiab rov kho dua. Thermosetting cua sov thiab phenolic resins thiab epoxy Resins raws li cov cua sov lossis kev ua haujlwm loj dua thiab lub zog kho tshuab hluav taws xob. Nyob rau hauv xyoo tas los, ntsuab synthesis technologies, xws li bio-}}}}}}}}}}}}}}}
Tshaj tawm {{0} Kev ua cov roj hmab thiab cov khoom yas kuj tseem ceeb, suav nrog kev ua kom zoo dua cov khoom siv moulding yam khoom thiab qhov kev siv tas. Nrog kev nce qib hauv kev tshawb fawb polymer, cov qauv siv hluav taws xob rau kev ua haujlwm roj hmab thiab cov kev ua phooj ywg muaj txiaj ntsig, thiab ua tau zoo kom tau raws li qhov xav tau kev lag luam tawm.
