Kwihlabathi lanamhlanje elikhawulezayo, imfuneko yezinto zokuncamathelisa ezisebenzayo nezithembekileyo yeyona ibalulekileyo.Imizi-mveliso ukusuka ekupakishweni ukuya kwiimoto zithembele kakhulu kwi-adhesives ukubonelela ixesha elide, iibhondi ezihlala ixesha elide.Isithako esiphambili esidlala indima ebalulekileyo ekuqulunqweni kwezinto zokuncamathelisa ezikumgangatho ophezulu yintlaka ye-hydrocarbon.Iinreyi zeHydrocarbon ziye zaba lukhetho oludumileyo phakathi kwabavelisi abancamathelayo ngenxa yeempawu zabo eziphezulu zokubopha kunye nokuguquguquka.
I-Hydrocarbon resins zi-polymers ze-petroleum eziye zabonakalisa ukuba zizithako ezixabisekileyo kwishishini lokuncamathelisa.Yiresin ye-thermoplastic eyenzelwe ngokukodwa ukunyusa ukusebenza ngokubanzi kwe-adhesives ngokuphucula i-tack, ukudibanisa kunye nokuhambelana.Le resin eguquguqukayo isetyenziswa kwiindidi ezahlukeneyo zokuncamathelisa ezifana nokunyibilika okushushu, ubuthathaka boxinzelelo kunye ne-adhesives-based adhesives.
Iipropathi ezigqwesileyo zokuncamathelisa i-hydrocarbon resins zibangelwa ikakhulu kubume bemolekyuli kunye neempawu ezizodwa.Iinreyithi zeHydrocarbon zinokubambelela kakuhle kwiintlobo ngeentlobo zesubstrates.Esi sixhobo siphezulu sokubambisana siqinisekisa ukuba i-adhesives eyenziwe nge-hydrocarbon resins inika amabhondi aqinileyo, athembekileyo nakwiimeko ezinzima.
Iinzuzo zokusebenzisa i-hydrocarbon resins kwi-adhesive formulations zininzi.Okokuqala, isebenza njenge-tackifier, iphucula iimpawu zokubambelela kwi-adhesive ngokunyusa i-tack yayo.Oku kubaluleke ngakumbi kwizicelo ezibuthathaka zoxinzelelo ezifana neeteyiphu zokupakisha okanye iilebhile, apho ibhondi yokuqala eyomeleleyo iyimfuneko.Iireyini zeHydrocarbon ziphucula intambo yokuncamathelisa kwaye iphucule amandla ayo okubopha ngokukhawuleza emva kokunxibelelana nesubstrate.
Okwesibini, i-hydrocarbon resins yomeleza ukudibanisa kwe-adhesives, okwenza kube nzima ukumelana noxinzelelo kunye nokugcina ingqibelelo yabo ekuhambeni kwexesha.Oku kunenzuzo ngakumbi kwizicelo apho i-adhesive idinga ukumelana namaqondo okushisa ahlukeneyo, umswakama okanye ezinye iimeko zokusingqongileyo.Ngokubandakanya i-hydrocarbon resins kwi-formulation yabo, abavelisi abanamathelayo banokuqinisekisa ukuba iimveliso zabo zinokumelana neemeko ezinzima ngaphandle kokuphazamisa amandla abo okudibanisa.
Enye inzuzo ebalulekileyo ye-hydrocarbon resins kukuhambelana kwazo kunye nezinye izinto ezincamathelayo.Inokudityaniswa ngokulula kunye noluhlu olubanzi lweepolymers, i-tackifiers kunye nezongezo, ezivumela abavelisi be-adhesive ukuba balungelelanise ukwakheka kwiimfuno ezithile.Oku kuguquguquka kwenza i-hydrocarbon resins ibe lolona khetho lubalaseleyo lokubumba izinto zokuncamathelisa ezineempawu ezinqwenelekayo ezifana ne-viscosity, ukuqina kunye nokuqina.
Kuyafaneleka ukuba uqaphele ukuba ukukhetha i-hydrocarbon resin efanelekileyo yokwakhiwa kwe-adhesive kubalulekile kwiziphumo ezilungileyo.Amanqanaba ahlukeneyo e-hydrocarbon resins anamanqanaba ahlukeneyo okuthambisa, ubunzima bemolekyuli kunye nokwakheka kweekhemikhali.Izinto ezifana nohlobo lwe-adhesive olufunwayo, indlela yokusetyenziswa, kunye neemfuno zokusebenza kufuneka ziqwalaselwe ngononophelo ngaphambi kokukhetha i-hydrocarbon resin efanelekileyo.
Ngokukhula kwemfuno yezinto ezincamathelayo zokusebenza eziphezulu, ukubaluleka kweeresin ze-hydrocarbon kweli shishini akunakugxininiswa.Iimpawu zayo ezigqwesileyo zokudibanisa, ukuhambelana kunye nokuguquguquka kwenza kube yinto yokuqala yokukhetha abavelisi be-adhesive emhlabeni jikelele.Ingaba i-bonding materials kwi-automotive assembly, iphucula izisombululo zokupakisha, okanye ukuphucula ukuqina kwezinto zokwakha, iiresin ze-hydrocarbon ziyaqhubeka zidlala indima ebalulekileyo kwishishini lokuncamathelisa.
Ukuqukumbela, i-hydrocarbon resins sisisombululo esiqinileyo sokunamathela.Ngeempawu zayo zokubambelela ezingenakulinganiswa, ukuhambelana nezinye izithako kunye nokuqulunqwa kwezinto ezininzi, kuqinisekisa ukuveliswa kwemigangatho ephezulu yokunamathela kwizicelo ezahlukeneyo.Njengoko ishishini liqhubeka nokukhangela izisombululo ezithembekileyo zokubambelela, ukubandakanya i-hydrocarbon resins kwi-adhesive formulations kuhlala kulukhetho oluhlakaniphile lokuqinisekisa iibhondi ezihlala ixesha elide, ezisebenzayo.
