Cov roj hmab ntuj yog lub ntuj polymer compound nrog polyisoprene ua cov khoom tseem ceeb.Nws cov qauv molecular yog (C5H8)n.91% mus rau 94% ntawm nws cov khoom yog roj hmab hydrocarbons (polyisoprene), thiab tus so yog cov protein, cov khoom tsis yog roj hmab xws li fatty acids, tshauv, suab thaj, thiab lwm yam. Cov roj hmab ntuj yog cov khoom siv dav dav siv roj hmab.
Composite roj hmab: Composite roj hmab txhais tau hais tias cov ntsiab lus ntawm cov roj hmab ntuj yog 95% -99.5%, thiab ib tug me me ntawm stearic acid, styrene-butadiene roj hmab, butadiene roj hmab, isoprene roj hmab, zinc oxide, carbon dub los yog pepizer ntxiv.Refined compound roj hmab.
Suav lub npe: hluavtaws roj hmab
Lub npe Askiv: hluavtaws roj hmab
Txhais: Cov khoom siv elastic heev nrog thim rov qab deformation raws li cov khoom siv hluavtaws polymer.
●Kev faib tawm ntawm cov roj hmab
Roj hmab feem ntau muab faib ua peb pawg: roj hmab ntuj, roj hmab sib xyaw, thiab roj hmab hluavtaws.
Ntawm lawv, cov roj hmab ntuj thiab cov roj hmab sib xyaw yog cov hom tseem ceeb uas peb tuaj yeem siv tam sim no;hluavtaws roj hmab hais txog cov muab rho tawm los ntawm cov roj av, yog li peb yuav tsis xav txog nws rau lub sijhawm.
Cov roj hmab ntuj (xws li roj hmab) yog hais txog cov roj hmab uas ua los ntawm cov roj hmab uas ua los ntawm ntuj.Cov roj hmab sib xyaw yog tsim los ntawm kev sib xyaw cov roj hmab ntuj nrog cov roj hmab hluavtaws me me thiab qee cov khoom siv tshuaj.
● Ntuj roj hmab
Cov roj hmab ntuj tau muab faib ua cov qauv roj hmab thiab cov ntawv haus luam yeeb raws li kev tsim khoom sib txawv.Standard roj hmab yog txheem roj hmab.Piv txwv li, Tuam Tshoj tus qauv roj hmab yog Standard roj hmab ntawm Tuam Tshoj, abbreviated li SCR, thiab zoo sib xws muaj SVR, STR, SMR thiab hais txog.
Cov kua nplaum txheem kuj muaj cov qib sib txawv, xws li SVR3L, SVR 5, SVR10, SVR20, SVR 50… thiab lwm yam;Raws li qhov loj ntawm tus lej, tus lej loj dua, qhov ua tau zoo dua;tus lej tsawg dua, qhov zoo dua qhov zoo (qhov tseem ceeb tshaj plaws kom paub qhov txawv ntawm qhov zoo thiab qhov tsis zoo Qhov tseem ceeb yog cov hmoov tshauv thiab impurity cov ntsiab lus ntawm cov khoom, cov tshauv tsawg dua, qhov zoo dua).
Smoked Sheet kua nplaum yog Ribbed Smoked Sheet, uas yog hais txog ib daim nyias nyias ntawm cov roj hmab, uas yog sau ua RSS.Cov ntawv luv no txawv ntawm cov qauv kua nplaum, thiab nws tsis raug cais raws li qhov chaw tsim khoom, thiab cov lus qhia yog tib yam hauv ntau qhov chaw ntawm kev tsim khoom.
Kuj tseem muaj cov qib sib txawv ntawm cov ntawv nplaum nplaum, RSS1, RSS2, RSS3, RSS4, RSS5, tib yam, RSS1 kuj yog qhov zoo tshaj plaws, RSS5 yog qhov tsis zoo.
● Composite roj hmab
Nws yog tsim los ntawm kev sib xyaw thiab kho cov roj hmab ntuj nrog cov roj hmab hluavtaws me me thiab qee cov khoom siv tshuaj.Cov qauv siv roj hmab feem ntau yog qhov no, xws li Malaysia's compound rubber SMR Compounded Rubber 97% SMR 20 (Malaysian standard rubber) + 2.5% SBR (styrene butadiene rubber, hluavtaws roj hmab) + 0.5% stearic acid acid).
Cov roj hmab sib xyaw yog nyob ntawm cov roj hmab ntuj uas tsim nws cov khoom tseem ceeb.Nws yog hu ua compound.Raws li saum toj no, lub ntsiab tivthaiv yog SMR 20, yog li nws yog hu ua Malaysia No. 20 txheem roj hmab compound;kuj tseem muaj cov ntawv luam yeeb thiab cov qauv roj hmab sib xyaw.
