Kuyini ukubopha?
Ukubopha kuyindlela yokuxhuma ngokuqinile izinto ezifanayo noma ezehlukene ndawonye usebenzisa amandla okunamathela akhiqizwa ingcina yokunamathisela endaweni eqinile. I-Bonding ihlukaniswe yaba izinhlobo ezimbili:ukuhlangana kwesakhiwo kanye nokuhlanganisa okungezona isakhiwo.
Iyini imisebenzi yokunamathela?
I-adhesive enamathelayo incike ekusebenzelaneni kwesixhumi esibonakalayo esibophezelayo, futhi ixhuma izinto ezimise okwehomogeneous noma ezihlukahlukene neziyinkimbinkimbi noma amadivaysi ngendlela yenqubo elula, kuyilapho inikeza imisebenzi ethile ekhethekile, njengokuvala uphawu, ukwahlukanisa, ukuqhutshwa kokushisa, ukuqhutshwa kukagesi, ukungena ngozibuthe. , ukugcwalisa, ukugcina kumthamo, ukuvikela nokunye. Okubili okuyisisekelo sokubopha ukunamathela nokubumbana. Ukunamathela kubhekisela ekukhangweni phakathi kwezindawo ezimbili ezihlukene, futhi ukuhlangana kubhekisela ekukhangweni phakathi kwama-molecule ezinto ngokwazo.
Yiziphi izindlela ezivamile zokuhlanganisa?
1. Ukuhlangana kwe-Butt: Iziphetho zama-substrates amabili ahlanganiswe nge-adhesive ahlanganiswe ndawonye, futhi indawo yokuxhumana yokubopha incane.
I-2.Ingxenye yekhona kanye ne-T- joint: Ixhunywe ekupheleni kwesisekelo esisodwa kanye nohlangothi lwenye into eyisisekelo.
- 3. I-Lap joint (i-flat joint): Ixhunywe emaceleni ezinto eziyisisekelo, futhi indawo yokubopha inkulu kune-butt joint.
- 4. Ijoyinti yesokhethi (eshumekiwe): faka umkhawulo owodwa wokuxhuma esikhaleni noma embobeni ebhontshiwe ngakolunye uhlangothi ukuze uhlangane, noma sebenzisa umkhono ukuze uxhume.
Yiziphi izici ezithinta umphumela wokubopha?
1. Izinto okufanele ziboshwe: ubulukhuni obungaphezulu, ukuhlanzeka kwendawo kanye ne-polarity yezinto, njll.;
2. Ukuhlanganisa amalunga: ubude, ukujiya kongqimba lwe-adhesive kanye nezinhlobo ezahlukene zamalunga;
3. Imvelo: indawo ezungezile (ukushisa/amanzi/ukukhanya/ioksijini, njll.), izinga lokushisa kanye nokushintsha kwezinga lokushisa kwendawo yokunamathisela;
4. Okunamathelayo: ukwakheka kwamakhemikhali, ukungena, ukufuduka, indlela yokwelapha, ingcindezi, njll.;
Yiziphi izizathu zokwehluleka kwesibopho?
Kunezizathu eziningi zokwehluleka kwesibopho, ezidinga ukuhlaziywa okuningiliziwe kwezimo ezithile. Izizathu ezijwayelekile zihlanganisa okulandelayo:
1. I-adhesive ne-base material ayihambelani, njengokuthi: ukuqhekeka kwenzeka phakathi kokukhishwa kwe-ethanol kanye ne-PC base material;
2. Ukungcoliswa komhlaba: Ama-ejenti akhululayo athinta ukubopha, ukugeleza kuthinta ukuvimbela okuthathu, ubuthi be-potting, njll.;
3. Isikhathi esifushane sokubopha/ingcindezi enganele: Ukucindezela okunganele noma isikhathi sokubamba ingcindezi kubangela umphumela omubi wokubopha;
4. Umthelela wezinga lokushisa/umswakama: i-solvent iyahwamuka ngokushesha futhi ingcina yesakhiwo iqina ngokushesha kakhulu;
Kungabonakala ukuthi isisombululo esifanelekile seglue sokubopha akumele sicabangele kuphela izinto ezibonakalayo, ukuma, isakhiwo kanye nenqubo yokunamathisela yezingxenye eziboshiwe, kodwa futhi sicabangele umthwalo kanye nesimo sezingxenye ezihlukahlukene eziboshiwe kanye nendawo ezungezile. Izinto ezinomthelela, njll. Uma unokuthile ongakuqondi noma udinga i-adhesive sealant, sicela uxhumaneSiway.
