Itheyiphu ekwazi ukumelana nokushisa okuphezulu ithandwa ngabasebenzisi ngoba ingamelana namazinga okushisa aphezulu kunamateyipu ajwayelekile.Uyazi ukuthi kungani amateyipu okushisa aphezulu akwazi ukumelana namazinga okushisa aphezulu kangaka?Uyazi ukuthi i-viscosity kanye nokuqina kwezinamathiselo zetheyiphu yokushisa okuphezulu zinakho kumateyipu okushisa aphezulu Ingabe kuyathinta?Okulandelayo, lalela umhleli womkhiqizi wamateyipu wezinga lokushisa eliphezulu wawo wonke umuntu.

I-polymer eqinile ye-thermosetting yetheyiphu ekwazi ukumelana nokushisa okuphezulu inokuguquguquka okungekuhle ngenxa yeketango elihlukanisiwe, futhi isakhiwo senethiwekhi esinezinhlangothi ezintathu esixhumene akulula ukusikeka ngemva kokuqiniswa, futhi singamelana nomthwalo ophakeme.Ama-polymers e-Thermoplastic awanawo amabhondi axhumanisa, ngaphansi kwesenzo samandla angaphandle, i-Oita chain deforms futhi iketango lihamba kancane kancane, okuholela ekuhlehleni.Izinga layo lesibili lobude liphakeme kunalelo lama-polymers e-thermosetting, kodwa umthwalo engawuthwala awuphezulu.

Impahla ye-elastomer yokushisa okuphezulu iqukethe izingxenye eziningi eziguquguqukayo engxenyeni ye-polymer, futhi ijwayele ukuguquguquka okubuyisela emuva ngaphansi kwesenzo samandla angaphandle.Ukuwohloka kwe-creep of thermoplastics kanye nokuguqulwa okunwebekayo kwama-elastomers kunciphisa ukugxila kwengcindezi yesampula ngaphansi kwesenzo samandla e-shear ngokwezinga elithile, futhi kunciphisa izinga lamandla emigqa onqenqemeni lokubopha lwesampula.I-resins ye-thermoplastic enesisindo esiphansi kanye ne-polyethylene polymer adhesives inezinga eliphezulu lokuguqulwa ngaphandle kokuphulwa ngaphansi kwesenzo samandla angaphandle, kodwa angakwazi ukumelana nomthwalo ophansi.

Ukuqina okunamathelayo kwetheyiphu yokushisa ephezulu ekuhlanganyeleni kwethanga kuthinta ngokuqondile amandla okugunda okuhlangene.Ngokuvamile, ukwanda kokuqina kwe-adhesive kuhambisana nokuncipha kwamandla okugunda okuhlangene.Kodwa-ke, akukhona ukuthi ubukhulu be-adhesive buncane ngangokunokwenzeka.Isendlalelo sokunamathisela esincanyana kakhulu sithambekele ekuntulekeni kweglue, futhi ukuntuleka kweglue kuba yisici sefilimu yokunamathisela.Uma ucindezelekile, ukucindezeleka okuzungezile iphutha kulula ukugxila, okusheshisa ukuphuka kwefilimu yokunamathisela.Ubukhulu obufanele be-adhesive buncike ekubunjweni kwekhanda lokubopha, uhlobo lomthwalo kanye nemvelo ye-adhesive.
