Abantu bangenye yendalo enhle kakhulu kankulunkulu, ngakho-ke abadali babantu babanikeza amalungelo athe xaxa okuhlola izindlela ezimnandi nezenjabulo. Onodoli abicah babiza kaningi kunodoli be-TPE. Onodoli abicah nabo babiza kakhulu kune-TPE. Ngakho-ke kungani ungathengi idoli yocansi bese ulisebenzisa ukwandisa impilo yakho yezocansi ngokuvala izithiyo zakho nomlingani wakho. Izindlela eziwusizo zokusebenzisa onodoli bezocansi kulawa makilasi.

Unodoli wezocansi we-TPE kumele kube yintuthuko enhle kakhulu abazoyithola abathandi bonodoli bezocansi. Ukukhanya kwamehlo kokuthwebula izithombe zodoli wombala kubaluleke kakhulu. Ukuma kokukhanya kweso esweni kunomthelela oqondile ekuvezeni kokukhanya kwamehlo. Khumbula ukuyivumela ivele maphakathi neso.

Ukuqedela ukwakheka kwesithombe sombala, kuyadingeka ukulungisa amalambu amaningi, kepha kufanele kulandelwe umthetho oyisisekelo wokukhanyisa, okungukuthi, isibani esisodwa kuphela esingasetshenziswa njengokukhanyisa okuyinhloko, nezinye izibani ziyasetshenziswa ukusiza ukukhanya okukhulu nokusiza ukukhanyisa ukwakha isithombe. .

Ngoba indela lihlala limnyama, uma uvumela amehlo avele maphakathi neso, kuzokwenza umonki omnyama abe mhlophe, kwenze lowo okhuluma ngale ndaba anikeze inkohliso yokuhlushwa yi-cataract. Ngakho-ke, indawo ekhanyayo yeso kufanele ivele ngaphandle kwendela. Isibani sangaphambili esivela kolunye uhlangothi siyindlela engcono yokukhanyisa, evumela iso ukuthi libe sesimweni esifanele. Ukuthungwa kwenjoloba nokuvumelana nezimo kukunikeza umuzwa wangempela owudingayo. Onodoli bezocansi be-TPE baqinile, bathambile futhi bayashintshashintsha, bafanele noma yimuphi umkhawulo. Zikunikeza ubumnandi obudingayo.

Dubula onodoli bombala basendlini, ngokusatshalaliswa kokukhanya, ungalawula umbala wesithombe, njengephrofayili ephezulu, iphimbo eliphakathi, ukhiye ophansi oshiwo ngenhla. Ngaphezu kwalokho, ukusatshalaliswa okuhlukile nokuhlungwa kombala kuzokhiqiza imiphumela ehlukile. Kufanele siphishekele ukuvumelana kombala nombala ekusetshenzisweni kwethoni yombala. Umhlaba wamathoyizi ocansi asuselwa kumathoyizi abicah. Kodwa-ke, unodoli wezocansi we-TPE manje ulapha futhi unikeza isiphetho esinzima sedoli le-silicone.

Uma umbala wangemuva uqinile, ngokuqhathanisa, lo mfanekiso unikeza ukubukeka okufiphele, okuyisicaba, nolayini wombukeli udonswa endaweni enemibala enamandla - ingemuva. Ukuze sisebenzise kangcono imibala ukusetha izinhlamvu, kufanele siqaphele ithonya lendawo ezungezile nombala wesigcawu kubalingiswa. I-Thermoplastic elastomer (TPE) iyi-polymer yenjoloba enezici ze-thermoplastic and elastic. Izinto ezikhona ezifana ne-vinyl ne-latex azinayo imizwa enjoloba ethambile.

Onodoli bezocansi be-TPE banezinzuzo kubo bobabili abakhiqizi nabasebenzisi. I-plasticity yayo iyivumela ukuthi ibunjwe ngendlela eyingqayizivele nonodoli ngentengo yokonga. Okomsebenzisi, ukuthungwa komzimba okuthambile, ukumunca ukushaqeka nokuguquguquka kunikezwa yilawa madoli.
