Njengoba isidingo sezinto zokunamathisela ezisebenza kahle kakhulu siqhubeka nokukhula kuzo zonke izimboni, isidingo sezixazululo zekhwalithi ye-resin siya ngokuya sibaluleke kakhulu. Ama-resin e-C5 hydrocarbon, ikakhulukazi uchungechunge lwe-SHR-18, abe yizithako ezithenjwayo neziguquguqukayo ekwenziweni kokunamathelayo.
I-C5 hydrocarbon resinikhiqizwa ngokuqhekeza ingxenyena ye-aliphatic C5, futhi umkhiqizo owumphumela unokuhambisana okuhle kakhulu, umbala ophansi kanye nokuzinza okuhle kokushisa. Uchungechunge lwe-SHR-18, ikakhulukazi, lwaziwa ngezakhiwo zalo ezisezingeni eliphakeme zokubopha, okulwenza lube ukukhetha okuphezulu kubakhiqizi abanamathelayo abafuna ukuthuthukisa ukusebenza komkhiqizo.
Enye yezinzuzo ezinkulu zokusebenzisa i-Uchungechunge lwe-SHR-18 lwe-C5ama-hydrocarbon resins ekwakhekeni kokunamathela yikhono lawo lokuthuthukisa i-tack nokunamathela. Ngokuhlanganisa le resin ekwakhiweni kokunamathela, abakhiqizi bangakwazi ukufeza isibopho esiqinile sokuqala, ngaleyo ndlela bathuthukise ukusebenza okuphelele nokuqina komkhiqizo wokunamathela. Lokhu kunenzuzo ikakhulukazi ezinhlelweni ezifana nokupakishwa, ukuhlanganisa kanye nezinamatheliso zezimoto, lapho ukubopha okuthembekile kubalulekile.
Ngaphezu kwalokho, i-Uchungechunge lwe-SHR-18inikeza ukuhambisana okuhle kakhulu nezinhlobonhlobo zama-polymers namanye ama-resin, okuvumela abaklami ukuthi bakhe izixazululo zokunamathela ezenziwe ngokwezifiso ezisekelwe kwizidingo ezithile zohlelo lokusebenza. Lokhu kuguquguquka kwenza ukuthuthukiswa kwezinamatheliso ezinezakhiwo ezahlukene, njengokuguquguquka, ukuqina nokuhlangana, ukuhlangabezana nezidingo ezihlukahlukene zezimboni ezahlukene.
Ngaphezu kwezakhiwo zayo zokunamathisela, uchungechunge lwe-SHR-18 lwe-C5 hydrocarbon resins futhi lusiza ukuthuthukisa ukuqina nokumelana okushisayo kwe-adhesive. Lokhu kubaluleke kakhulu ezinhlelweni zokusebenza lapho okunamathelayo kungaphansi kwamazinga okushisa aphezulu noma ukuchayeka ngaphandle, njengoba inhlaka isiza ukugcina ubuqotho bebhondi yokunamathela ngaphansi kwezimo zemvelo eziyinselele.
Uchungechunge lwe-SHR-18 lufaka amaphuzu ahlukene okuthambisa, okunikeza abaklami ukuguquguquka ukuze bavumelanise izici ze-rheological kanye ne-viscosity zokwakheka kwazo okunamathelayo. Lokhu kuvumelana nezimo kubalulekile ekuzuzeni indlela yokufaka efiselekayo kanye nokusebenza kokugcina komkhiqizo wokunamathisela.
Kafushane, uchungechunge lwe-SHR-18 lwezinhlaka ze-hydrocarbon ze-C5 lunikeza izinzuzo eziningi zokunamathisela okunamathelayo, okuhlanganisa i-tack ethuthukisiwe nokunamathela, ukuhambisana okuhle kakhulu, ukuzinza okushisayo kanye nokwakheka kwezinto ezihlukahlukene. Ukusetshenziswa kwayo ekwenziweni kokunamathela kuye kwafakazelwa ukusiza ukuthuthukisa ukusebenza komkhiqizo nokuhlangabezana nezidingo eziguqukayo zezimboni ezahlukahlukene. Njengoba isidingo sezinto zokunamathisela ezisezingeni eliphezulu siqhubeka sikhula, uchungechunge lwe-SHR-18 luyaqhubeka nokuba yisinqumo esithembekile kubakhiqizi abanamathelayo abafuna ukuthuthukisa ukusebenza komkhiqizo.
