Izikhombisi-ndlela ezintsha zohlelo lokusebenza kanye nezimpawu ze-Adhesives (2)
- 1. Ukumelana nezinga lokushisa
Izinamatheliso zokushisa okuphezulu kwe-Inorganic zivame ukusetshenziswa ebangeni elingu-1500-1750℃, kuyilapho izinamathiselo ze-copper phosphate oxide zinebanga elibanzi lokumelana nezinga lokushisa futhi zingasetshenziswa ebangeni elingu-180-1400℃. Kodwa-ke, ama-aggregates ayinhloko asetshenziswa ekunamatheleni okushisa okuphezulu kwe-inorganic isihlabathi se-zircon kanye nenhlabathi ephikisayo. Isihlabathi se-Zircon sibiza kakhulu futhi sincike kakhulu ekuthengeni kwamanye amazwe, futhi inhlabathi ephikisayo kufanele itholakale ngezindleko zomhlaba, okuyizindleko ezinkulu. Ngakho-ke, kubalulekile ukuthola imikhiqizo eshibhile futhi etholakala kalula ukuze ubuyisele izilinganiso zendabuko ukuze kwehliswe izindleko zokukhiqiza. Amanye ama-adhesive aphilayo nawo azuze ukumelana nezinga lokushisa eliphezulu ngokuguqulwa. Isibonelo, iglue ye-phenolic resin elungiswe nge-B4C ingamelana namazinga okushisa angu-1500 ℃. Isidingo semakethe sezinto ezinamathelayo ezimelana nokushisa sikhula njalo, ngakho lolu hlobo lokunamathisela lunamathemba abanzi okuthuthuka.
- 2. Ukungcola okuphansi
Njengoba isimo somhlaba siwohloka, abantu kancane kancane baqala ukusebenzisa imikhiqizo ethile engayingeni imvelo. Nakuba izinto zokunamathela zingesona isigaba esikhulu semikhiqizo yamakhemikhali, ukulimala kwazo endaweni ezungezile akunakunakwa. Lezo zinamathiselo ezingezona-ezinobungani bemvelo zizoyekwa kancane kancane. I-Polyethylene formaldehyde adhesive (evame ukwaziwa ngokuthi "iglue engu-107") iqukethe i-formaldehyde yamahhala, eyingozi empilweni yomuntu. Sekuyisikhathi eside ivinjelwe emazweni athuthukile, kodwa ezweni lami, ngenxa yentengo ephansi, isenayo ingxenye enkulu yemakethe. Nokho, ukusetshenziswa kwayo kuye kwehla kancane kancane futhi kuzoqedwa maduzane. Uzishintsha kanjani izinto ezinamathelayo ezingezona-ezinobungani bemvelo zibe izinto ezinamathelayo ezithinta imvelo kuwumsebenzi obalulekile.
- 3. Ukuhlangana okungekona ukucekela phansi
Izindlela eziyinhloko zokuxhuma izinto zifaka i-bolting, i-riveting, i-welding kanye ne-bonding. Nakuba i-bolting nobunye ubuchwepheshe bungafinyelela ukuxhumana okusheshayo, zizolimaza izinto ngenxa yokumboza noma ukushisisa kwasendaweni kwezingxenye zezinto ezibonakalayo, futhi ukugxilisa ingcindezi ngeke kugwenywe ngesikhathi sokusetshenziswa. Ngokuphambene, ubuchwepheshe bokuxhumana buwubuchwepheshe bokuxhuma onge-nokonakalisa, futhi ngenxa yokuthi isixhumi esibonakalayo sesibopho sithwala umthwalo sisonke, sithuthukisa umthamo womthwalo futhi sandise impilo yesevisi.
4. Engasindi
Ubuningi bezinto zokunamathisela buphansi kakhulu, ikakhulukazi phakathi kuka-0.9 no-2, okungaba ngu-20% kuya ku-25% wesisindo sensimbi noma izinto ezingaphili, ngakho-ke kunganciphisa kakhulu isisindo sezinto zokuxhuma zento enamathelayo.
