Njengoba imboni yezokwelapha iqhubeka nokukhula, imishini yezokwelapha kanye namadivayisi kuya ngokuya kuthuthuka kakhulu ekusingatheni amakhemikhali aqinile, izidakamizwa kanye namazinga okushisa. Ukukhetha uphawu olufanele lwezinhlelo zezokwelapha kubalulekile ekusebenzeni kahle kwedivayisi iyonke.
Izivalo zezokwelapha zisetshenziswa ezinhlotsheni ezahlukene, okuhlanganisa amaphampu ezokwelapha, izingxenye ze-IV, amadivayisi okuphakela kanye nezinto zokufakelwa. Inhloso yezivalo zezokwelapha ukuvikela abantu kanye namadivayisi ekuvuzeni okuyingozi. Zisetshenziswa lapho uketshezi noma amagesi epompiwa, ekhishwa amanzi, edluliselwa, equkethwe noma ekhishwa.
Kunezinto eziningi okufanele uzikhumbule lapho ukhetha isivalo esifanele sedivayisi yezokwelapha. Nazi ezinye zezinto ezibalulekile okufanele uzicabangele lapho wenza isinqumo.
Khetha izinto ze-elastomer ezifanele.
Ukuze ukhethe uphawu olufanele, udinga ukuqonda kuqala uhlelo lokusebenza olukhona. Kufanele ucabangele ukuthintana okungenzeka, izinga lokushisa, ukunyakaza, ingcindezi kanye nokuthi uphawu ludinga ukuhlala isikhathi esingakanani.
Izimbobo zezokwelapha kumele zibonise ukumelana namakhemikhali anamandla, anobuthi. Kungase kube nezidingo ezithile zekhwalithi yezinto ze-elastomer zesimbobo. Ukuze imelane futhi iqinisekise ukumelana namakhemikhali, kubalulekile ukuthi isimbobo senziwe ngama-elastomer asebenza kahle kakhulu futhi asezingeni eliphezulu. I-Apple Rubber isebenzisa i-Liquid Silicone Rubber, i-Viton® Fluoroelastomer kanye ne-Ethelyne-Propylene. Lawa ma-elastomer anezimo zokumelana namakhemikhali ezithuthukisiwe, ukumelana nokushisa okuhle kakhulu kanye nokungangeni kahle kwegesi.
Qaphela ukuhambisana kwezinto eziphilayo.
Amadivayisi ezokwelapha awahlali ethintana nezicubu eziphilayo. Kodwa-ke, lapho amadivayisi nezimbonakaliso zithinta izicubu zabantu nezinye izinto ezibalulekile njengoketshezi lomzimba, izidakamizwa noma uketshezi lwezokwelapha, kubalulekile ukuqaphela ukuhambisana kwezinto eziphilayo kwenhlanganisela yokuvala.
Ukuhambisana kwezinto eziphilayo kusho ukuthi izakhiwo zezinto eziphilayo ziyahambisana nezinto eziphilayo futhi azinikezi ukusabela noma impendulo esicutshini esiphilayo. Ukuqinisekisa ukuthi akukho ukusabela okuzokwenzeka ngesikhathi sokusetshenziswa kwezokwelapha, kubalulekile ukuhlola ukuhambisana kwezinto eziphilayo kwesivalo bese ukhetha into ngokusekelwe ohlotsheni lomsebenzi wokusetshenziswa.
Ezinye izinto zinokungcola.
Kuhlale kubalulekile ukucabangela ukungcola kwezinto zokuvala. Ngokuhamba kwesikhathi, ukungcola kungaphuma esivalweni ngezinto ezinobuthi noma ezibangela umdlavuza. Ezisetshenzisweni zezokwelapha lapho amadivayisi nezimbobo zithintana ngqo nezicubu zomuntu, ngezinye izikhathi zize zifakwe, kubaluleke kakhulu ukuqaphela ubuthi obungaba khona bezinto. Ngenxa yalesi sizathu, onjiniyela kufanele bakhethe izinto zokuvala ezingenakungcola okuningi noma ezingenakho nhlobo.
Ngaphansi kokukhanya okufanayo, kubalulekile ukuqaphela ukuthi impahla kufanele ibulawe yini inzalo. Uma kusetshenziswa izinto ezithinta izicubu eziphilayo, yonke idivayisi yezokwelapha kufanele ingabi namagciwane ukuvimbela ukutheleleka.
