Irabha yendalo yi-polymer yendalo ene-polyisoprene njengeyona nto iphambili. Ifomula yayo yemolekyuli yi-(C5H8)n. 91% ukuya kwi-94% yeenxalenye zayo zii-hydrocarbon zerabha (i-polyisoprene), kwaye ezinye ziiproteni, Izinto ezingezizo zerabha ezifana nee-fatty acids, uthuthu, iiswekile, njl. Irabha yendalo yeyona isetyenziswa kakhulu kwinjongo eqhelekileyo.
Irabha edityanisiweyo: Irabha edityanisiweyo ithetha ukuba umxholo werabha yendalo yi-95%-99.5%, kwaye kongezwa inani elincinci le-stearic acid, irabha ye-styrene-butadiene, irabha ye-butadiene, irabha ye-isoprene, i-zinc oxide, i-carbon black okanye i-peptizer. Irabha edityanisiweyo ecociweyo.
Igama lesiTshayina: irabha yokwenziwa
Igama lesiNgesi: irabha yokwenziwa
Inkcazo: Yinto ethambileyo kakhulu enokuguqulwa okuguquguqukayo okusekelwe kwiikhompawundi zepolymer zokwenziwa.
●Udidi lwerabha
Irabha yahlulwe kakhulu yahlulwe yaba ziindidi ezintathu: irabha yendalo, irabha edityanisiweyo, kunye nerabha yokwenziwa.
Phakathi kwazo, irabha yendalo kunye nerabha edibeneyo zezona ntlobo ziphambili esizingenisa kwamanye amazwe okwangoku; irabha yokwenziwa ibhekisa kwezo zikhutshwe kwi-petroleum, ngoko ke asiyi kuyiqwalasela okwangoku.
Irabha yendalo (irabha yendalo) ibhekisa kwirabha eyenziwe ngezityalo ezivelisa irabha yendalo. Irabha edityanisiweyo yenziwa ngokuxuba irabha yendalo nerabha encinci eyenziweyo kunye nezinye iimveliso zeekhemikhali.
● Irabha yendalo
Irabha yendalo yahlulwe yaba yirabha eqhelekileyo kunye nerabha yephepha elitshisiweyo ngokweenkqubo ezahlukeneyo zokwenziwa. Irabha eqhelekileyo yirabha eqhelekileyo. Umzekelo, irabha eqhelekileyo yaseTshayina yirabha eqhelekileyo yaseTshayina, efinyezwa njenge-SCR, kwaye ngokufanayo kukho i-SVR, STR, SMR njalo njalo.
Iglue eqhelekileyo ikwanazo neendidi ezahlukeneyo, ezifana ne-SVR3L, SVR 5, SVR10, SVR20, SVR 50… njl.; ngokobungakanani benani, okukhona inani lilikhulu, kokukhona umgangatho usiba mbi; okukhona inani lincinci, kokukhona umgangatho usiba ngcono (eyona nto ibalulekileyo yokwahlula phakathi kokulungileyo nokubi. Ingongoma kukuba uthuthu kunye nokungcola kwemveliso kuncinci, kokukhona umgangatho usiba ngcono).
Iglu yeshiti etshayiweyo yiRibbed Smoked Sheet, ebhekisa kwisiqwenga esincinci serabha etshayiweyo, esifinyeziweyo njengeRSS. Esi sifinyezo sahlukile kwiglu esemgangathweni, kwaye asihlelwanga ngokwendawo yemveliso, kwaye indlela esetyenziswa ngayo iyafana kwiindawo ezahlukeneyo zemveliso.
Kukwakho neendidi ezahlukeneyo zeglue yephepha elitshisiweyo, i-RSS1, i-RSS2, i-RSS3, i-RSS4, i-RSS5, iyafana, i-RSS1 ikwangumgangatho ongcono, i-RSS5 ngumgangatho ombi kakhulu.
● Irabha edityanisiweyo
Yenziwa ngokuxuba nokucoca irabha yendalo ngerabha encinci eyenziweyo kunye neemveliso ezithile zeekhemikhali. Eyona fomula yerabha edibeneyo esetyenziswa kakhulu yile, njengerabha edibeneyo yaseMalaysia i-SMR Compounded Rubber 97% SMR 20 (irabha eqhelekileyo yaseMalaysia) + 2.5% SBR (irabha ye-styrene butadiene, irabha eyenziweyo) + 0.5% stearic acid acid).
Irabha ehlanganisiweyo ixhomekeke kwirabha yendalo eyakha icandelo layo eliphambili. Ibizwa ngokuba yi-compound. Njengoko kungasentla, icandelo eliphambili yi-SMR 20, ngoko ke ibizwa ngokuba yi-Malaysia No. 20 standard rubber compound; kukwakho ne-smoke sheet compound kunye ne-standard rubber compound.
