Ama-Adhesive, axhuma ngokuqinile izinto ezimbili noma ngaphezulu zokunamathela eziye zaphathwa phezulu futhi zinezakhiwo zamakhemikhali ezinamandla athile omshini. Isibonelo, i-epoxy resin, i-phosphoric acid i-copper monoxide, i-latex emhlophe, njll. Lokhu kuxhumana kungaba unomphela noma kukhipheke, kuye ngohlobo lwe-adhesive nezidingo zohlelo lokusebenza.

Ngokombono wokwakheka kwamakhemikhali, izinto zokunamathisela ngokuyinhloko zakhiwe ngezinto zokunamathisela, izincibilikisi, ama-ejenti okwelapha, ama-filler, ama-plasticizers, ama-coupling agents, ama-antioxidants nezinye izinto ezisizayo. Lezi zithako zihlangene zinquma izakhiwo ze-adhesive, njenge-viscosity, isivinini sokuphulukisa, amandla, ukumelana nokushisa, ukumelana nesimo sezulu, njll.

Izinhlobo zokunamathela

I.I-Polyurethane adhesive
Isebenza kakhulu futhi i-polar. Inokunamathela okuhle kakhulu kwamakhemikhali ngezinto eziyisisekelo eziqukethe igesi esebenzayo, njengegwebu, ipulasitiki, izinkuni, isikhumba, indwangu, iphepha, izitsha zobumba nezinye izinto ezinama-porous, kanye nensimbi, ingilazi, irabha, ipulasitiki nezinye izinto ezinobushelelezi..

II.Epoxy resin adhesive
Yakhiwe kusuka ku-epoxy resin base material, i-ejenti yokwelapha, i-diluent, i-accelerator ne-filler. Inokusebenza okuhle kokubopha, ukusebenza okuhle, intengo ephansi uma kuqhathaniswa nenqubo elula yokubopha.

III.Cyanoacrylic adhesive
Kudingeka ukwelapha lapho ungekho umoya. Okubi ukuthi ukumelana nokushisa akuphakeme ngokwanele, isikhathi sokuphulukisa side, futhi asifanele ukuvala uphawu ngezikhala ezinkulu.

IV.Polyimide esekelwe ingcina
Ingcina yembewu ekwazi ukumelana nokushisa okuphezulu ekwazi ukumelana nokushisa futhi ingasetshenziswa ngokuqhubekayo ku-260°C. Inokusebenza okuhle kakhulu kwezinga lokushisa eliphansi kanye nokufakwa kwe-insulation. Ububi ukuthi i-hydrolyzed kalula ngaphansi kwezimo ze-alkaline.

I-V.Phenolic resin adhesive
Inokumelana nokushisa okuhle, amandla okubopha okuphezulu, ukumelana kahle nokuguga kanye nokufaka ugesi okuhle kakhulu, futhi ishibhile futhi kulula ukuyisebenzisa. Kodwa futhi kungumthombo wephunga le-formaldehyde efenisha.

I-VI.Acrolein-based adhesive
Uma isetshenziswa ebusweni bento, isincibilikizo sizohwamuka, futhi umswakama ongaphezulu kwento noma ovela emoyeni uzobangela i-monomer ukuthi ingene ngokushesha kwi-anionic polymerization ukuze yakhe iketango elide neliqinile, elihlanganisa izindawo ezimbili ndawonye.

VII.Izinamathiselo ze-Anaerobic
Ngeke iqine uma ithinta umoya-mpilo noma umoya. Uma umoya usuhlukanisiwe, uhambisana nomthelela we-catalytic wendawo yensimbi, ungenza i-polymerize futhi uqinise ngokushesha ekamelweni lokushisa, wakhe isibopho esiqinile kanye nophawu oluhle.

VIII.Inorganic adhesive
Ingakwazi ukumelana nokushisa okuphezulu kanye nezinga lokushisa eliphansi futhi inezindleko eziphansi. Akulula ukuguga, ngesakhiwo esilula nokunamathela okuphezulu.

IX.Ingcina encibilikayo eshisayo
Ingcina ye-thermoplastic esetshenziswa esimweni esincibilikisiwe bese ihlanganiswa lapho ipholiswe ibe yisimo esiqinile. Ezimpilweni zansuku zonke, ingasetshenziswa njengencwadi ebopha izinto.

Uma ukhetha i-adhesive, udinga ukucabangela izici ezifana nemvelo yokunamathela, izimo zokuphulukisa ze-adhesive, indawo yokusetshenziswa kanye nomnotho. Isibonelo, ngezikhathi ezidinga ukuthwala imithwalo emikhulu, izinamathiselo zesakhiwo ezinamandla aphezulu kufanele zikhethwe; ngezinhlelo zokusebenza ezidinga ukwelapha ngokushesha, izinamathiselo ezinejubane lokuphulukisa ngokushesha kufanele zikhethwe.

Ngokuvamile, ama-adhesive adlala indima ebalulekile ekukhiqizweni kwezimboni zanamuhla kanye nempilo yansuku zonke. Abagcini nje ukwenza lula inqubo yokuxhuma futhi banciphise izindleko, kodwa futhi bathuthukise ikhwalithi nokuthembeka kwemikhiqizo. Ngokuthuthuka kwesayensi nobuchwepheshe kanye nokwenza ngcono ukuqwashisa ngemvelo, izinto zokunamathisela ezizayo zizoba nobungane kakhulu endaweni ezungezile, zisebenze kahle futhi zibe nemisebenzi eminingi.

Ngemva kokuqonda kafushane ukuthi i-adhesive iyini kanye nezinhlobo zayo, kungase kufike omunye umbuzo engqondweni yakho. Hlobo luni lwezinto ezingasetshenziswa ngezinamathiselo? Sicela ulinde futhi ubone esihlokweni esilandelayo.
