Umkhiqizi Wokuphrinta Wezitikha Ezingokwezifiso Kusukela ngo-2005
Ukugoba amalebula, ukuxebuka kanye nezinsalela ezinamathelayo kuvame ukonakalisa ulwazi lwamakhasimende futhi kulimaze isithombe somkhiqizo, ikakhulukazi okubeka izingozi ezinkulu emithini nasemikhiqizoni yamakhemikhali.
Inkinga akuyona nje inhlaka ebuthakathaka. Iphinde ihlobane nokufanisa izinto zelebula, ukuthungwa kwendawo, izinga lokushisa kanye nomswakama lapho kuthuthwa futhi kugcinwe khona. Ukuhlanza izindawo ezomile kanye nokungabi namabhamuza omoya kubalulekile. Ukukhetha izinto ezifanele kanye namakhono okunamathela afanele kungagwema ngokuphelele ukuxebuka kwelebula.
Sinamathelisa amalebula emikhiqizweni ngokunganaki ekuphileni kwethu kwansuku zonke, kodwa asiqapheli ukuthi angase angahambisani. Kuhle ukucabanga ngokuthi ubuso buyini—ukuthungwa nokwakheka kwawo, ngaphambi kokukhetha into yokulebula kanye ne-glue efanele.
Uma ufuna izindawo eziqinile njengebhokisi lekhadibhodi noma ukhuni? Zama ukusebenzisa inhlaka eqinile ehlanganiswe nezinto ezigobekayo, uyazi.
Empeleni, le nhlanganisela isebenza kahle ngempela—ingahambisana nokuthungwa okungalingani. Lokho kuvimbela imiphetho ukuthi ingagobeki futhi kuvimbele amalebula ukuthi angaphuki.
Abanye amalebula ezimonyo futhi amalebula okudla zinamathiselwe ekupakishweni kwezinto ezinjalo. Isibonelo, ngemikhiqizo efana nama-lotion, izithelo, kanye naleyo enokuqukethwe okuphezulu kwamafutha, kubalulekile ukukhetha izinti ezinamathelayo ezingamelani namafutha kanye nama-plasticizer. Ngaphandle kwalokho, i-glue ingahluleka uma ihlangana nalezo zithako.
Kukhona futhi amanye amalebula afana nalawa: amalebula eziphuzo futhi amalebula ewayini ; lezi zidinga ukunamatheliswa emabhodleleni epulasitiki noma engilazi. Lezi zindawo zibushelelezi, futhi amalebula ajwayelekile azophuma ngemva kwesikhathi eside. Kunconywa ukukhetha ezinamathelayo eziqinile.
Ngokombono wami, izinto ezisebenzisa amandla aphansi ongaphezulu azigcini amalebula kahle uma kungenjalo. Ungase uthole lawo malebula egoqeka noma eqhekeka kalula kakhulu.
Eqinisweni, indawo ezungezile idlala indima enkulu ekutheni kungani amalebula ephuka. Udinga ngempela ukucabangela izinga lokushisa noma ngabe lelo lebula linamathele kuphi. Kushisa kakhulu? Nokho, inhlaka ingancibilika noma ithambe, ivumele ilebula isheleleke ngokushesha. Kubanda kakhulu?
Kwenza iglue iqhekeke – imifantu iqala ukubonakala. Bese kuba nomswakama. Uma umswakama emoyeni uphezulu kakhulu, umswakama ungena phakathi kwelebula kanye nobuso.
Inhlaka ilahlekelwa ukubamba kwayo kancane kancane. Ikakhulukazi, lapho amalebula ethunyelwa ezindaweni ezisogwini noma egcina egcinwe engaphansi komhlaba okumanzi. Ngisho nangesikhathi sokuthutha okuvamile, uma izinga lokushisa noma umswakama kushintsha kancane lokho kuvame ukwanele ukuwenza aqhekezeke.
Singathanda ukusebenzisa izinto zokwenziwa ezifana ne-PET, i-PP, noma i-PE ukuze sithole amalebula. Azigobeki noma zivuvuke ngenxa yomswakama njengoba kwenza iphepha elimboziwe, futhi amazinga okushisa abandayo ngeke awenze aqhekeke. Uma ungakwazi ukushintsha ngokwesabelomali, amalebula asekelwe efilimini angcono kakhulu ekuxazululeni lezi zinkinga.
I-glue egcwele i-acrylic empeleni iyisinqumo esithembekile sokuthumela izinto amabanga amade. Ayigcini nje ngokukwazi ukumelana namazinga okushisa asukela ku--40°C kuya ku-120°C, kodwa futhi imelana nemisebe ye-UV.
| Ibanga Lokushisa | Isimo Sokunamathela Nokuqina | Izinga Lokunamathela | Ukuziphatha Okubalulekile Nezinkinga | Imikhawulo Ejwayelekile Yohlelo Lokusebenza |
| Ngaphansi kuka -20°C (-4°F) | Iqine kakhulu, injengengilazi, iyaphuka | Ukuqina okuphansi kakhulu / okubi | I-Adhesive iyaqina, ilahlekelwa ikhono lokumanzisa; kulula ukuyikhipha noma ukuyiqhekeza | Akunconywa ukulebula |
| -20°C kuya ku-0°C (-4°F kuya ku-32°F) | Kuqinile, kuqinile kakhulu | Okuphansi kuya kokuphakathi | Ukuncipha kokuqala; ukubopha okuhamba kancane; kungavela ezindaweni ezibushelelezi | Izinga lokushisa eliphansi lokusetshenziswa kwama-PSA amaningi ajwayelekile ≈ 5°C |
| 0°C kuya ku-15°C (32°F kuya ku-59°F) | Kuqinile kancane, ukujiya kuyakhuphuka | Okumaphakathi | Ukubamba okuhle kokuqala kodwa ukwakheka kwesibopho okuhamba kancane; kuyasebenza kodwa akunamandla kakhulu | Kuyamukeleka ukusetshenziswa endlini; gwema ukuhamba ngebhayisikili okubandayo kakhulu |
| 15°C kuya ku-35°C (59°F kuya ku-95°F) | Ukuthamba okuthambile, okulinganiselayo | Okuhle kakhulu / okuphezulu | Ukubopha okuhle kakhulu, ukubopha okusheshayo, nokususwa okuhlanzekile | Ifasitela lokusebenza elijwayelekile lamanothi anamathelayo ehhovisi namalebula ephepha |
| 35°C kuya ku-60°C (95°F kuya ku-140°F) | Ithambile, i-viscosity ephansi | Kuphezulu kodwa kuyehla | I-Adhesive iyathamba; ingase iphume, iphakamise unqenqema, noma ishintshe lapho ithwalwa | Kulungile okwesikhashana; ukushisa okuhlala isikhathi eside kubangela "ukugeleza okubandayo" |
| Ngaphezulu kuka-60°C (140°F) | Ithambile kakhulu, ifana noketshezi | Okuphansi / ukwehluleka | Ukuthamba okukhulu, ukusala kwensalela ezindaweni, ukugoba/ukuhlukanisa ilebula | Izinamathiseli ezihlala njalo ziyahluleka; amanothi angashintshwa alahlekelwa ukusebenza ngokuphelele |
Ngokuvamile sinaka kakhulu ukukhetha ilebula neglue engcono. Kodwa into ethile esiyishaya indiva lapho sifaka ilebula kufanele iqashelwe.
Kungakhathaliseki ukuthi ikhwalithi inhle kangakanani, eminye imininingwane esingayinaki izoqhubeka ibangela ukuthi ilebula liqhekeke futhi ligobe.
Okokuqala, kusadingeka unake izinga lokushisa lendawo. Ukuqinisekisa ukuthi inhlaka elebula elinamathiselwe igeleza ngendlela evamile futhi inamandla okunamathela.
Ukusebenzisa utshwala ukuhlanza indawo ngaphambi kokufaka ilebula ukuqinisekisa ukuthi akukho uthuli noma uwoyela. Ukujuluka, amafutha noma uthuli ezandleni zethu kuzohlala endaweni enamathelayo.
Singagqoka amagilavu akhethekile ukuze sigweme ukuthintana nendawo yerabha ngezandla ngqo. Lokhu kuvimbela ukuthintana okuqondile phakathi kwento yokunamathisela nendawo. Ngokuhamba kwesikhathi, amalebula azowa futhi aphenduke.
Uma ubhala amalebula, sicela uqaphele ukuthi uhlangothi olulodwa lwelebula kufanele lunamathiselwe ebusweni bento kuqala. Khetha izitika zendawo ezisicaba, ezibamba amehlo, ezingagugi futhi ugweme imithungo noma amabala angalingani.
Ukugoqa amalebula ngesandla ukuze kukhishwe umoya futhi kugwenywe ukwakheka kwamabhamuza. Gxila ekwenzeni bushelelezi imiphetho namakhona elebula. Ngemva kokunamathisela, kufanele futhi sinake indawo yokugcina. Khetha indawo epholile, eyomile, enomoya, gwema ukukhanya kwelanga okuqondile kanye nokushisa okuphezulu.
Ulwazi oluhlanganyelwe ngenhla luthemba ukuthi luzokusiza ukuxazulula izinkinga zokukhuhla nokuphakamisa amalebula. Uma ufuna ukwazi okwengeziwe ngemikhiqizo yamalebula noma ulwazi oluhlobene nawo, sicela ukhululeke uku Xhumana nathi !
Ngezinto zokuhlola ezihlomele kahle kanye namandla obuchwepheshe aqinile, sinemishini eminingana yokunyathelisa ye-rotogravure yangaphakathi kanye nemishini yokunyathelisa ilebula ezenzakalelayo ngokugcwele.
