191 resin thiab 196 resin yog o-phenylene unsaturated resins, uas muaj nyob rau hauv kev lag luam fiberglass.
Yog li dab tsi yog qhov txawv ntawm 191 resin thiab 196 resin? Muaj peb lub ntsiab lus tseem ceeb:
1. Cov yam ntxwv sib txawv
191 resin cov khoom muaj me me shrinkage thiab zoo mechanical zog, thaum 196 resin yog ib tug semi-rigid resin nrog zoo cuam tshuam tsis kam thiab cov khoom siv ntev dua.
2. Cov ntawv thov sib txawv
191 resin feem ntau yog siv los ua qhov cua ducts, thaum 196 resin haum rau cov rooj tog zaum, cov khoom cam khwb cia, thiab lwm yam.
3. Cov ntsiab lus sib txawv
196 resin yog ib qho kev daws teeb meem ntawm polyester thiab styrene, uas muaj kev cuam tshuam zoo tiv thaiv . 191 resin tsis tshua muaj viscosity thiab zoo stability.
191 resin thiab 196 resin yog ob yam khoom sib txawv. Lawv txawv heev. Txawm hais tias lawv yog ob qho tib si unsaturated resins, lawv yog ob hom resin qib. Thaum siv lawv, koj yuav tsum kawm paub qhov txawv ntawm ob cov ntaub ntawv no. Yog tias koj tab tom ua lub plhaub fiberglass lossis lwm yam, nws raug nquahu kom siv 196 resin. Rau kev siv dej tsis zoo thiab tiv thaiv - daim ntawv thov corrosion, 191 resin yuav pheej yig dua.
Kev ceeb toom sov: Lub sij hawm cia ntawm cov resin qis dua 25℃yog peb mus rau rau lub hlis (peb lub hlis rau ua ntej- nrawm resin thiab rau lub hlis rau cov uas tsis yog-pre- nrawm nrawm). Lub sij hawm cia siab tshaj 30℃yuav luv ntxiv.
