Sebenzisa i-Mhec ukuthuthukisa ukuqina kwama-putty

I-Putty iyinto eguquguqukayo esetshenziswa kabanzi ekwakheni, ukulungisa izimoto, kanye nezinye izimboni ezahlukahlukene. Kodwa-ke, ukuzinza kwayo, ikakhulukazi ngokuya ngokubambisana kanye nokunamathelisa, kungaba yinkinga kwezinye izinhlelo. Lo mbhalo uhlola ukusetshenziswa kwe-hydroxyyethylyls eguquliwe (i-MHEC) njengesengezo sokuthuthukisa ukuqina kokuqina kwama-tutty. I-MHEC i-cellulose etholwa ngezakhiwo eziyingqayizivele ze-rheological kanye ne-adhesive ethuthukisa ukusebenza kwama-putty.

I-PuTTY iyinto esetshenziswa kakhulu ekwakheni, ukulungisa izimoto, kanye nezicelo ezahlukahlukene zezimboni ngenxa yokusebenza okuhlukahlukene, ukukhululeka kokusebenzisa, kanye nekhono lokugcwalisa izikhala nokungahambi kahle. Kodwa-ke, ukuqina kwe-putty, ikakhulukazi izakhiwo zayo zokubumbana nokunamathela, kubalulekile ukuqinisekisa ukusebenza kwayo nokuqina kwayo ezicelo ezahlukahlukene. Izici ezahlukahlukene, njengezimo zezemvelo, izakhiwo ezingezansi kanye nezithako zokwakheka, zingathinta ukuqina kwe-putty.

Eminyakeni yamuva nje, kube nentshisekelo eyandayo ekuhloleni izithasiselo ukuthuthukisa ukuqina nokusebenza. Enye engezansi yesengezo iguqulwa i-hydroxyyethyl celtulose (Mhec), i-cellulose derivative eyaziwa ngezakhiwo zayo eziyingqayizivele ze-rheological kanye nokunamathela.

Ukuqina okubeka: imiqondo nezinselelo
Ukuqina kwama-putty kubhekisele emandleni ayo okugcina izakhiwo zayo ezingokomzimba nezemishini ngokuhamba kwesikhathi, ikakhulukazi ngaphansi kwezimo ezahlukahlukene zezemvelo kanye nezingcindezi zemishini. Ukuqina kwe-putty kuthintwa yizici ezahlukahlukene, kufaka phakathi ukusebenza kwalo okusemthethweni, ukunamathela ku-substrate, ukumelana nokuguquguquka, kanye nokusulwa kokuqhekeka noma ukomisa.

Izakhiwo ze-Rheological zidlala indima ebalulekile ekunqumeni ukuqina kwama-putty. I-Putty kufanele ibe nokubonakala okufanele futhi icindezele ukucindezela ukuqinisekisa ukusetshenziswa okulula nokunamathela ku-substrate. Ngaphezu kwalokho, indlela yokuziphatha e-Thixotropic (i-viscoty ye-putty incipha ngaphansi kwengcindezi ye-shear futhi iphinde iqale ukubonakala kwayo ngemuva kokuthi ingcindezi ngemuva kokuphela kwengcindezi) ilungele ukuthuthukisa ukucubungula kanye nokuphikiswa kwe-sag.

I-Adhesion ingesinye isici esingukhiye sokuqina kwe-putty njengoba inquma ukuthi uPuturety uzobopha kanjani ama-substrates ahlukahlukene anjengezinkuni, zensimbi noma ukhonkolo. Adhesion ampofu angenza ukuthi i-putty ibe yibala noma ikhafule kude ne-substrate, ukuyekethisa ubuqotho bokulungiswa komhlaba. Ngaphezu kwalokho, i-Putty kufanele ibonise ukuhlangana okuhle ukuze ilondoloze ubuqotho bayo ngokwesakhiwo futhi ivikele ukugcwala noma ukuwa ngesikhathi sohlelo lokusebenza nokwelapha.

Inselelo ekuzuzeni ukuzinza okuphelele kwe-Putty kufaka nokuthola ibhalansi efanelekile yezakhiwo ze-Rheological, abagqugquzeli abanama-adhesion kanye nezithasiselo, ngenkathi kucatshangelwa izidingo ezithile zezicelo ezahlukahlukene kanye nezimo zemvelo. Ngakho-ke, izindlela ezintsha ezifana nokungezwa kwezithasiselo ezifanele ezifana ne-MHEC zidinga ukuthuthukisa kahle ukuqina kwama-tupties.
