Umhlahlandlela Owusizo Wezinto Ezinamathelayo

Umhlahlandlela Osebenzayo Wezinto Ezinamathelayo----Impilo Yeshelufu, Amandla Ebhondi, Nezinyathelo Ezibalulekile Zokuqapha

Izinamatheliso ziwuhlobo lomkhiqizo wamakhemikhali osetshenziswa yiwo wonke umuntu empilweni yansuku zonke. Izinamatheliso ezijwayelekile zifaka i-super glue, itheyiphu ekabili-esemaceleni, itheyiphu yokunamathela, izinti zeglue, nokunye. Namuhla, sizokwabelana ngamathiphu awusizo okusebenzisa lezi zinamathiselo. Ngiyaqiniseka ukuthi lapho uqeda ukufunda lesi sihloko, uyobe usuzuze okuthile okubalulekile.

Phakathi nenqubo yokuhlanganisa ingcina, umxhumanisi ohlanganisa izinto ezimbili—okungukuthi, ingcina ngokwayo—ikakhulukazi isesimweni esimanzi. Ingokwesigaba samakhemikhali amahle futhi iza ngezinhlobonhlobo eziningi. Ihlukaniswa ngokuyinhloko ngokwesisekelo sokunamathela (i-binder), isimo somzimba, indlela yokwelapha, kanye nempahla yama-substrates azohlanganiswa. Ngamafuphi, impumelelo yokubopha incike ku-30% ku-adhesive kanye ne-70% kwinqubo (inqubo).

1. I-Shelf Life

1. Wonke umkhiqizo unesikhathi seshelufu esicacisiwe. Ngokwezindinganiso zamazwe ngamazwe, impilo yeshalofu ichazwa ngaphansi kwezimo zokushisa zegumbi (24°C). Ngezinto zokunamathisela ze-acrylic, izinga lokushisa eliyinkomba lingu-20°C.

2. Emikhiqizweni ye-acrylic-esekelwe, izinga lokushisa liphezulu, liba mfushane impilo yeshalofu.

3. Emikhiqizweni-esekelwe emanzini, amazinga okushisa angaphansi kuka--1°C azothinta ngokuqondile ikhwalithi yomkhiqizo.

1. Amandla

1. Ayikho into efana ne-adhesive yendawo yonke emhlabeni. Kuma-substrates ahlukene, kungcono ukhethe ingcina ekhethekile eyenzelwe leyo nto ethile.

2. Uma i-substrate ngokwayo inamandla aphansi emvelo, asikho isidingo sokukhetha i-adhesive ephezulu-amandla; uma kungenjalo, uzobe usuqedile-ucacisa futhi ukhuphule izindleko ngokungadingekile.

3. Ungagxili kuphela emandleni aphezulu esibopho sokuqala; ukuqina kufanele futhi kucatshangelwe okufanele.

4. Izinamatheliso ezilapha ezingeni lokushisa eliphezulu ngokuvamile zinikeza ukusebenza okungcono kakhulu kunalezo ezilashwa ekamelweni lokushisa. Uma kudingeka amandla aphezulu nokuqina okuhle, kufanele kukhethwe okunamathelayo okwelapha izinga lokushisa eliphezulu.

5. Ngezinto ezinamathelayo ze-Ethyl2-Cyanoacrylate (502 super glue), ngaphandle kokulungiswa kwesimo esiphuthumayo, okuncane-okupeshiswa kwendawo, noma izinhlelo zokusebenza zomugqa wokukhiqiza okuqhubekayo, azinconyelwe izinto ezidinga amandla okubopha okuphezulu.

1. Okunye Ukucatshangelwa

1. Iglue emhlophe (i-PVA adhesive) kanye ne-urea-formaldehyde resin adhesives ngeke kusetshenziselwe ukubopha izinsimbi.

2. Ngezinhlelo zokusebenza ezidinga ukukhanya, ungakhetha izinto zokunamathisela ze-polyurethane, izinto zokunamathisela epoxy optical, izinamatheliso ze-polyester ezigcwele, noma izinamatheliso ze-polyvinyl acetal.

3. I-adhesive akufanele idle ku-substrates eboshiwe. Isibonelo, izinto zokunamathisela ezincibilikisiwe-ezisekelwe ku-neoprene akufanele zisetshenziswe kumabhodi egwebu enziwe nge-polystyrene anwetshiwe.

4. Ama-Adhesives ane-brittleness ephezulu awafanele ukubopha izinto ezithambile noma eziguquguqukayo.

1. Izinyathelo Zokusebenzisa Izinamathiselo Ezimbili-Ingxenye (AB).

1. Okubili-okunamathelayo kwengxenye, landela njalo isilinganiso sokuxuba esishiwo encwadini yeziqondiso.

2. Ngaphambi kokusetshenziswa, izingxenye ezimbili kufanele zixutshwe kahle futhi zifane. Ungashiyi noma yiziphi izindawo ezingaxutshiwe; uma kungenjalo, i-adhesive ngeke ilaphe.

3. Ama-substrates kumele ahlanzwe kahle futhi angabi namanzi (ngaphandle uma i-adhesive yakhelwe ukuphulukiswa ngaphansi kwamanzi).

4. Ukuze kuzuzwe amandla okubopha okuphezulu, ama-substrates kufanele agwetshwe (afakwe isihlabathi) ngangokunokwenzeka.

5. Umklamo wejoyinti elihlanganisiwe uthinta ngokuqondile amandla esibopho sokugcina.

6. I-adhesive kufanele ixutshwe futhi isetshenziswe ngokushesha. Ungayishiyi imile isikhathi eside kakhulu ngemva kokuyixuba. Ezinhlotsheni ezisheshayo-ezilaphayo, isikhathi sokusebenza akufanele sidlule imizuzu emi-2.

7. Uma kufunwa amandla aphezulu kanye nokwelapha ngokushesha, ukushisisa kungase kusetshenziswe ngendlela efanele. Uma usebenzisa i-adhesive, ungqimba akufanele lube lukhulu kakhulu; mayelana 0.5 mm Kunconywa. Izendlalelo eziwugqinsi empeleni zinciphisa ukusebenza kahle kokubopha.

8. Ngesikhathi sokubopha, kungcono ukufaka ingcindezi noma uvikele izingxenye ngezinsimbi.

9. Ukuze uthole amandla amakhulu, vumela umhlangano oboshiwe uphumule okungenani amahora angu-24 ngemva kokubopha.

10. Ukuze uthole-into eyodwa encibilikisayo-esekelwe noma emanzini-okunamathelayo, hlala ushukumisa kahle ngaphambi kokusetshenziswa.

11. Ngemikhiqizo encibilikisiwe-esekelwe, ngemva kokufaka ingcina, vumela indawo eboshiwe ukuthi ibe nomoya-yome ize ingasabambeki ngaphambi kokuhlanganisa izingxenye.
