Igedlela liwumshini ojwayelekile wokugibela amabanga amade. Kudingeka sibe nokuqonda okujulile ngayo ukuze siyisebenzise ngenjabulo nangokuphepha! Igedlela kufanele kube umkhiqizo wenhlanzeko yomuntu siqu. Iqukethe uketshezi oluphuzwa esiswini. Kumele kube nempilo futhi kuphephe, ngaphandle kwalokho isifo sizongena ngomlomo futhi sichithe injabulo yohambo. Amabhodlela amanzi ebhayisikili njengamanje asemakethe angahlukaniswa ngokwezigaba ezimbili: amabhodlela epulasitiki namabhodlela ensimbi. Amabhodlela epulasitiki angahlukaniswa abe izinhlobo ezimbili: iglue elithambile neglue eliqinile. Amabhodwe ensimbi nawo ahlukaniswe abe amabhodwe e-aluminium namabhodwe ensimbi engagqwali. Izigaba ezingenhla zincike kakhulu ekuhlukaniseni izinto kanye nokuqhathaniswa kwalezi zinto ezine ezihlukene.
Ipulasitiki ethambile, ibhodlela lamanzi lebhayisikili elikhanyayo elimhlophe elinesabelo esikhulu semakethe lenziwe ngalo. Ungaphendula iketela ulibhekise phansi futhi uzothola ezinye izimpawu eziphrintwe ngezincazelo zezinto ezibonakalayo. Uma zingekho ngisho lezi futhi kungenalutho, kunconywa ukuthi ushayele ku-12315 ngokushesha ukuze ubike lo mkhiqizo mbumbulu. Eduze kwasekhaya, iziqukathi zepulasitiki ngokuvamile ziba nelogo encane engunxantathu ngezansi, futhi kunenombolo yesi-Arabhu phakathi nelogo, ukusuka ku-1-7. Ngayinye yalezi zinombolo imele into ethile, futhi kunezinkolelo ezihlukene ekusetshenzisweni kwazo. Ngokuvamile, amaketela eglue athambile enziwe nge-No. 2 HDPE noma No. 4 LDPE. Ipulasitiki No. 2 izinzile futhi ingakwazi ukumelana nokushisa kuze kufike ku-120 degrees Celsius, kodwa ipulasitiki No. 4 ayikwazi ukubamba amanzi abilayo ngokuqondile, futhi izinga lokushisa eliphezulu lamanzi alikwazi ukudlula ama-degree angu-80, ngaphandle kwalokho lizokhipha ama-agent epulasitiki angakwazi ukubola umzimba womuntu. Into ecasulayo kakhulu ukuthi kungakhathaliseki ukuthi uyigcwalisa ngamanzi ashisayo noma abandayo, kuhlale kunephunga elimnandi leglue emlonyeni wakho.
I-Hard glue, ummeleli odume kakhulu okuyibhodlela lamanzi lebhayisikili le-OTG le-Nalgene elivela e-United States. Laziwa ngokuthi “ibhodlela elinganqamuki”. Kuthiwa ngeke iqhume noma igingqika imoto, iyakwazi ukumelana nokushisa nokubanda. Kodwa ukuze sibe sohlangothini oluphephile, ake sibheke phansi kuqala. Kukhona nonxantathu omncane onenombolo “7” phakathi. Inombolo "7" yikhodi ye-PC. Ngenxa yokuthi isobala futhi imelana nokuwa, isetshenziswa kakhulu ekwenzeni amaketela, izinkomishi namabhodlela ezingane. Eminyakeni embalwa edlule, kwakunezindaba zokuthi amaketela e-PC azokhipha i-hormone yemvelo i-BPA (bisphenol A) lapho evezwe ukushisa, okungaba nemiphumela emibi emzimbeni womuntu. Noma kunjalo, uNalgene uphendule ngokushesha futhi wethula into entsha, ebizwa ngokuthi “BPAFree”. Kodwa ingabe azoba khona amaqhinga amasha atholakele esikhathini esizayo esiseduze?
Nge-aluminium emsulwa, adume kakhulu amaketela ezemidlalo e-Swiss Sigg, abuye akhiqize amaketela ebhayisikili, namaketela e-French Zefal aluminium. Kuyiketela eliphezulu le-aluminium. Uma ubhekisisa, uzobona ukuthi ungqimba lwayo lwangaphakathi lunoqweqwe, okuthiwa luvimbela amagciwane futhi luvimbele ukuthintana okuqondile phakathi kwe-aluminium namanzi abilayo ukuze kukhiqizwe amagciwane. Kuthiwa futhi i-aluminium izokhiqiza amakhemikhali ayingozi uma ihlangana noketshezi olune-asidi (ijusi, i-soda, njll.). Ukusetshenziswa isikhathi eside kwamabhodlela e-aluminium kungase kubangele ukulahlekelwa inkumbulo, ukuncipha kwengqondo, njll. (okungukuthi isifo i-Alzheimer's)! Ngakolunye uhlangothi, i-aluminium emsulwa ithambile futhi yesaba kakhulu amaqhuqhuva futhi izohluka lapho yehliswa. Ukubukeka akuyona inkinga enkulu, into embi kakhulu ukuthi i-coating izoqhekeka futhi umsebenzi wokuzivikela wokuqala uzolahleka, okuyoba yize. Kodwa ingxenye embi kakhulu ukuthi, kuvela ukuthi lezi zembatho zokwenziwa nazo ziqukethe i-BPA.
Insimbi engagqwali, uma kuqhathaniswa, amaketela ensimbi engagqwali awanayo inkinga yokumboza, futhi angenziwa abe ungqimba olukabili. Ngaphezu kokufakwa kwe-thermal, ene-double-layered nayo inenzuzo yokuthi ingabamba amanzi ashisayo ngaphandle kokushisa izandla zakho. Ungacabangi ukuthi awuwaphuzi amanzi ashisayo ehlobo. Ngezinye izikhathi ezindaweni lapho ongayitholi khona idolobhana noma isitolo, ulwazi olulethwa amanzi ashisayo lungcono kakhulu kunamanzi abandayo. Esimeni esiphuthumayo, igedlela lensimbi engagqwali elinesendlalelo esisodwa lingabekwa ngqo emlilweni ukuze kubiliswe amanzi, okuyinto amanye amaketela angeke akwazi ukuyenza. Namuhla, amaketela amaningi afuywayo ensimbi engagqwali ayikhwalithi enhle futhi amelana kakhulu namaqhubu. Nokho, amabhodlela amanzi ensimbi engagqwali ayasinda futhi asindayo uma egcwele amanzi. Amakheji ebhodlela lamanzi epulasitiki emabhayisikili ajwayelekile angase angakwazi ukubekezelela. Kunconywa ukuthi esikhundleni sazo nge-aluminium alloy water bottle cages.
