Iigranules zerabha ziimveliso eziphambili ezivela kwiinkqubo zokuphinda zisetyenziswe xa kusetyenziswa inkunkuma, zisebenza njengekhonkco elibalulekileyo phakathi kokulahlwa kwenkunkuma yerabha kunye nokusetyenziswa kwakhona kwezixhobo. Ngokungafaniyo nezinto zerabha ezingavuthwanga, iigranules zerabha zisebenzisa amatayara alahliweyo, afumaneka kakhulu kwaye angabizi kakhulu, nto leyo eyenza ukuba afaneleke kakhulu kwiindlela ezahlukeneyo zoshishino nezoluntu. Ukuveliswa kweegranules zerabha kubandakanya amanyathelo amaninzi aqatha kubandakanya ukuqhekeza amatayara, ukwahlulwa kwentambo yentsimbi, ukutyumza irabha, ukususa ukungcola kunye nokubeka imigangatho. Ukuqhekeza amatayara kuqhekeza amatayara amakhulu alahliweyo abe ziingceba ezincinci zerabha ukuze kusetyenzwe emva koko; ukwahlulwa kwentambo yentsimbi kususa izinto zesinyithi ezifakwe kwiingceba ngetekhnoloji yokwahlula irabha ngemagnethi ukuqinisekisa ubunyulu berabha; ukutyumza irabha kunciphisa ngakumbi izingceba zerabha zibe ziingceba ezincinci; ukususa ukungcola kususa inkunkuma eseleyo efana nefayibha nothuli; ukubeka imigangatho kwahlula amatayara kwiinkcukacha ezahlukeneyo ngokusekelwe kwiimfuno zesicelo. Inyathelo ngalinye lenzelwe ngononophelo ukugcina ukuthamba kwerabha kunye nokumelana nokuguguleka ngelixa kusenziwa amatayara afanayo ahlangabezana nemigangatho yesicelo eyahlukileyo. Iimpawu zomzimba ezikhethekileyo zegranules zerabha, ezifana nokufunxwa okumangalisayo, ukusebenza okuthembekileyo kokungatyibiliki kunye nokumelana nokugqwala okunamandla, kuzenza zibe nokuguquguquka kwiindawo ezininzi ngaphaya kwamashishini emveli.

Ishishini lokubuyisela inkunkuma kwiigranule zerabha lixhomekeke kakhulu kwiigranule zerabha njengeemveliso eziphambili, njengoko zinciphisa ngempumelelo uxinzelelo lokusingqongileyo olubangelwa kukufunxwa kwenkunkuma yamatayara kunye nokutshisa—iindlela ezimbini zokulahla ezidla ngokukhokelela kungcoliseko kunye nenkunkuma yezixhobo. Ngexesha lenkqubo yokubuyisela inkunkuma, iigranule zerabha ezinobuncinci obahlukeneyo ziveliswa ukuze zihambelane neemfuno ezahlukeneyo: iigranule zerabha ezincinci, ezinobukhulu obuncinci nobufanayo bee-particle, zifanelekile ukuxuba nezinye izinto ezifana neepolymers kunye ne-bitumen ukuphucula ukusebenza kwemveliso, ngelixa iigranule zerabha ezirhabaxa, ezinobukhulu obukhulu bee-particle kunye nobunzima obuphezulu, zihlala zisetyenziselwa ukuzalisa kunye nokugcina ii-padding kwiiprojekthi zokwakha. Iigranule zerabha ezisetyenzisiweyo kwakhona zibonisa ukuhambelana okuhle neepolymers, i-bitumen kunye nekhonkrithi, nto leyo evumela ukuba zisetyenziswe kakhulu ekwenzeni izinto ezidityanisiweyo kunye nokwakhiwa kwezakhiwo ezahlukeneyo, ngaloo ndlela zandisa umda wazo wokusetyenziswa kumacandelo okwakha kunye nawokuvelisa. Amashishini amaninzi olawulo lwenkunkuma agxila ekuphuculeni iinkqubo zemveliso, njengokuphucula izixhobo zokutyumza kunye nokuphucula ukuchaneka kokubeka amanqaku, ukuphucula isivuno kunye nomgangatho weegranule zerabha, ukuqinisekisa ukuba inkqubo yokubuyisela iyasebenza kwaye ithembekile.

Ukuhlaziywa komphezulu wezemidlalo yenye indawo ebalulekileyo apho iigranule zerabha zidlala indima engenakutshintshwa. Amabala emidlalo amadala kunye neendlela zokubaleka zihlala zinengxaki yokuguguleka komphezulu, ukuqhekeka kunye nokulahlekelwa kukufunxwa komothuko ngenxa yokusetyenziswa ixesha elide kunye nokukhukuliseka kwendalo, kwaye iigranule zerabha ziba zizinto ezifanelekileyo zokuhlaziywa ngenxa yeempawu zazo ezizodwa. Xa zisetyenziswa kwiindlela zokubaleka eziphinda zifakwe umphezulu, iigranule zerabha zihlala zixutywa nee-polyurethane binders ukwenza umphezulu oxineneyo nothambileyo onciphisa impembelelo kwizixhobo zemidlalo, unciphise ukuguguleka kwezixhobo, kwaye uphucule ukhuseleko ngokubanzi lweendawo. Ekuhlaziyweni kwengca yokwenziwa yamabala ebhola ekhatywayo kunye neendawo zokudlala, iigranule zerabha zisetyenziswa njengezinto zokufaka izinto ukuze kubuyiselwe ukuthe tye kwefayibha yengca—ukuthintela iifayibe ekubeni zithe tyaba ngokunyathela rhoqo—nokuphucula ukuthamba komphezulu, ukubonelela ngamava emidlalo akhululekileyo nakhuselekileyo. Iigranule zerabha ezinemibala, ezicutshungulwa ngokongeza imibala enobuhlobo nokusingqongileyo, nazo ziyasetyenziswa kakhulu ekuhlaziyweni komphezulu wezemidlalo. Zingasetyenziselwa ukwenza iipateni ezahlukeneyo kunye neebhloko zemibala ukuze kuhlaziywe inkangeleko yendawo ngelixa kugcinwa ukumelana nemozulu okuhle kakhulu kunye nozinzo lwe-UV, ukuqinisekisa ukuba imibala ayififi lula phantsi kwelanga elide. Iiprojekthi zokuhlaziya ezisebenzisa iigranule zerabha zihlala zifuna ukukhethwa okungqongqo kwezinto ukuqinisekisa ukuba iigranule zerabha ziyahlangabezana nemigangatho efanelekileyo yokusingqongileyo kunye nokusebenza, njengokungazinzi okuphantsi kunye nokumelana nokuguguleka okuphezulu.

Icandelo lemizi-mveliso likwabona ukwanda kokusetyenziswa kwee-granules zerabha, kunye neempawu zazo ezisetyenziswa ngokupheleleyo kwiimeko ezahlukeneyo zemveliso kunye nokusebenza. Ekwenzeni ii-mats kunye nee-cushion zoshishino, ii-granules zerabha zidityaniswe nezinto ezenziweyo ezifana ne-PVC kunye ne-EVA ukuvelisa iimveliso ezinokunyusa ukufunxwa komothuko kunye nemiphumo yokunciphisa ingxolo. Ezi mveliso zisetyenziswa kakhulu kwiifektri, kwiindawo zokugcina impahla nakwiindawo zokuhambisa izinto—umzekelo, zibekwe phantsi koomatshini abanzima ukunciphisa ukungcangcazela kunye nengxolo, okanye zisetyenziswe njengee-mats zokulwa nokudinwa kwabasebenzi abame ixesha elide. Ii-granules zerabha zongezwa nakwii-coatings ezingangeni manzi ukuphucula ukuguquguquka kwe-coat kunye nokumelana nokuqhekeka, okwenza ukuba ii-coat zilungelelanise nokuguquguquka okuncinci kwezakhiwo zesakhiwo ngaphandle kokuqhekeka, ngaloo ndlela zandisa ubomi benkonzo yokwakha iileya ezingangeni manzi. Ekugcinweni kwendlela, ii-granules zerabha ezixutywe ne-asphalt zisetyenziselwa ukulungisa imingxuma kunye nokutywina umphezulu. Lo mxube unamathele kakhulu kumphezulu wendlela wokuqala, unokugcwalisa ngokukhawuleza imingxuma kunye nokutywina imingxunya, uthintele ngokufanelekileyo amanzi emvula ukuba angene kwisiseko sendlela kwaye ubangele umonakalo ongakumbi kumphezulu wendlela. Ezi zicelo zoshishino zisebenzisa ngokupheleleyo iipropati zomzimba zee-granules zerabha, zizisa iingenelo zoqoqosho kumashishini ngokunciphisa iindleko zokulungisa kunye nokuphucula ukusebenza kakuhle ngelixa zisombulula iingxaki ezisebenzayo kwimveliso nasekusebenzeni.

Iindidi ezahlukeneyo zeegranule zerabha zineempawu ezahlukeneyo ezihambelana nezicelo ezithile, ezihlangabezana neemfuno ezahlukeneyo zamashishini ahlukeneyo. Iigranule zerabha zamatayara ezisetyenzisiweyo, ezenziwe ngamatayara alahliweyo, zibiza kancinci kwaye zihambelana kakuhle nezinto ezininzi, ngoko ke zisetyenziswa kakhulu kwiindawo zokuzalisa nokwakha ezifana nokuzalisa isiseko sendlela kunye nokudibanisa isiseko sesakhiwo. Iigranule zerabha ezenziweyo ezifana neegranule zerabha ze-SBR kunye ne-EPDM, eziveliswa ngokwenziwa kweekhemikhali, zinozinzo olungcono lweekhemikhali, amandla aphezulu okutsalwa kunye nokumelana okungcono nokwaluphala kunye ne-oxidation xa kuthelekiswa neegranule zerabha zamatayara ezisetyenzisiweyo. Ke ngoko, zifanelekile kwiimeko ezifunwa kakhulu njengeendawo zemidlalo zobungcali—apho ukusetyenziswa kwexesha elide kunye neemeko ezinzima zokusingqongileyo zifuna ukusebenza okuphezulu kwezinto—kunye nezixhobo zoshishino ezifuna ukumelana nokugqwala kweekhemikhali. Inkqubo yokuvelisa iigranule zerabha ezenziweyo ibandakanya ukulinganiswa okuchanekileyo kwezinto kunye nolawulo oluqinileyo lokucubungula ubushushu ukuqinisekisa ubungakanani obuhambelanayo beenhlayiya kunye nokusebenza okuzinzileyo kwemveliso yokugqibela. Zombini iigranule zerabha ezisetyenzisiweyo kunye nezonziweyo zivavanyelwa umgangatho ongqongqo ngaphambi kokuba ziphume efektri, zigubungela iinkalo ezifana nokusasazwa kobungakanani beenhlayiya, amandla okutsalwa, ukumelana nokwaluphala kunye nomxholo wezinto eziguquguqukayo ukuqinisekisa ukuba ziyahlangabezana neemfuno zesicelo.
