Elihambayo amabhande. izakhiwo Special nezici.

Omunye izici ezibaluleke kakhulu we amabhande elihambayo linjengamafutha petrol ukumelana. Le nkulumo ibhekisela ikhono opholile isikhathi eside ukuze bayise imikhiqizo, kuhlanganise ketshezi amafutha amaminerali, ukudla oily, noma "uwoyela ehlanzekile" (ngokuvamile briquetted) ne ukuvuvukala sakugcina amapuleti amabhodi. Kwezinye izimo, ngaphezu ukumelana amafutha nokushisa ukumelana liyadingeka. Ngokwesibonelo, lapho ebeka hot asphalt imishini yokuthutha izinto.

Kufanele kukhunjulwe ukuthi Amafutha ibhande petrol ukumelana kancane, eliqinile kuka tape jikelele-njongo, ngoba ngamandla enamathela yayo iraba lingaphansi kakhulu. Ngokuvamile, iraba enamathela zikhethwa uhlobo ngamunye amafutha (kumakhemikhali awuketshezi, njll) ziye ihlolwe ku izixazululo okujwayelekile (ingxube isooctane futhi toluene) kungukuthi njalo ukuqinisekisa ephephile ukusebenza bands ezimweni ezithile.

Nokwethenjelwa opholile uwoyela nophethiloli ukumelana icaciswa ngokushesha ngokwanele - ngaphakathi 3-4 ezinsukwini zokuqala ukusebenza (iraba ukuvuvukala izinga esiphezulu lapho besanda kuqala bese lehla ngokucijile). Kukholakala ukuthi ukumelana kakhulu "abezindaba oily" - ibhande elihambayo nge plate PVC.

Endaweni aqueous, kuhlanganise esihlanza amanzi olwandle, ibhande uwoyela ukumelana inhloso jikelele futhi uthembeke ngokuphelele (ukuvuvukala iraba esingeqile 2.5 - 3%).

Heat ukumelana - ikhono bands ukulondoloza ukusebenza nalapho bethutha imithwalo ashisayo. Lapho ithonya lokushisa Izakhiwo kanye mechanical iraba kanye Indwangu kakhulu liwohloka (isb, lapho amandla besigaxa isibopho incipha ngo izikhathi 2 ezingeni lokushisa 100 ° C, Ukuwohloka enamathela iraba luyanda 2 - 2.5 izikhathi). Futhi ngesikhathi ukuchayeka njalo ukuya phezulu lokushisa ukuguga kwenzeka kuze kudabuke umhlane, isb ushintsho engelapheki e izakhiwo. Ngenxa yalezi nemibandela ingasebenza Linings ekhethekile ukushisa ukumelana iraba nge ukushuba sithuthukiswe (engengaphansi kwengu-6 mm), futhi "setha" lenyuka ukuphepha wekhasi ukuze uzimele - 15-20 nesibaya (I-jikelele-njongo opholile kuba ukuqinisela 8-10).

Kufanele kukhunjulwe ukuthi ayanda endaweni ukuxhumana kobuso ashisayo wezimpahla liner, isb kunalokhu oyikho "ezincane", izimo obuqinile yokusebenza itheyiphu kancane isikhathi eside. Ngakho iyosebenza izidingo ephakeme ukusebenza opholile.

Frost - ikhono ihlanganise ukunyakaza imithwalo ibhande ngaso -60 ° C kuma lokushisa nangaphezulu, isb silondoloze kuyaqina ngesikhathi ukuqoqa sigubhu ezinamasondo, "evamile" yakha ugqoko. Ukusebenzisa jikelele injongo amabhande e mibandela kuholela amaza ngokujulile electrode kanye aba isidumbu phezu conveyer ukusebenza.

Ukumelana Frost inikezwa usebenzisa opholile parietal akhethekile uthayi sezinsini. Ngaphambi opholile obandayo ezimweni ezinjena Kunconywa ukuba zikwazi ukuqhubeka ziphila kuleli izimo "efudumele" (okungenani + 6 + 8 ° C) lokungenani emahora lalingana langu-12.
