Esikubonayo emakethe, kungakhathaliseki ukuthi ubhiya, utshwala, iwayini, iwayini lezithelo, noma iwayini lezempilo, iwayini lomuthi, kungakhathaliseki ukuthi hlobo luni lwepakethe yewayini namabhodlela engilazi ayengenakuhlukaniswa nebhodlela lengilazi, ikakhulukazi kubhiya kukhona umbukiso owengeziwe. Ibhodlela lengilazi liyisitsha sokupakisha isiphuzo sendabuko ezweni lakithi, futhi ingilazi nayo iwuhlobo lwezinto zokupakisha ezinokubaluleka okukhulu komlando. Ngezinhlobonhlobo zezinto zokupakisha ezitheleka emakethe, iziqukathi zengilazi zisabambe isikhundla esibalulekile ekufakweni kwesiphuzo, esingenakuhlukaniswa nezici zayo zokupakisha ezingenakuthathelwa indawo ezinye izinto zokupakisha.
Kuyaqondakala ukuthi u-71% weziqukathi zikabhiya emhlabeni zenziwe ngengilazi, kanti iShayina iyizwe elinengxenye enkulu yamabhodlela kabhiya emhlabeni, ibalwa ku-55% wawo wonke amabhodlela kabhiya ayingilazi, edlula amabhodlela ayizigidi eziyizinkulungwane ezingu-50 unyaka ngamunye. Ngaphandle kwamabhodlela engilazi, angikaze ngibone okunye ukupakishwa kwewayini, iwayini lezempilo, iwayini lomuthi namanye amawayini emakethe. Lokhu kungabonakala endaweni ebalulekile yamabhodlela engilazi emaphaketheni ewayini. Pho kungani amabhodlela ewayini amaningi kangaka enziwe ngengilazi?
Okokuqala, kufanele igezwe nge-alkali ngaphambi kokugeza ibhodlela. Uma ibhodlela lepulasitiki lisetshenziselwa ukulifaka, kulula ukusabela nge-alkali, futhi ibhodlela lengilazi alikwazi nje ukusabela nge-alkali, ngakho-ke ukuhlanzeka kanye nekhwalithi yebhodlela lewayini kuyathuthukiswa;
Okwesibili, ubhiya ngokwawo uqukethe igesi eningi efana ne-oxygen, i-carbon dioxide, njll., ikakhulukazi i-carbon dioxide izoqhuma lapho ibhekene nokungqubuzana okunamandla, okuwukuphela kokushoda kwamabhodlela engilazi;
Okwesithathu, ezitsheni zokupakisha ezibonwa emakethe, ibhodlela lengilazi kuphela elibushelelezi futhi linokuxubana okuphansi, isivinini sokugeleza okusheshayo, nokusebenza kahle kokukhiqizwa kwamanzi;
Okwesine, lapho ibhodlela lewayini lidlula emshinini wokuvala inzalo, izinga lokushisa langaphakathi le-poplar yokuvala inzalo likude nokushisa okwedlulele kwepulasitiki, okulula ukuguqulwa, futhi ukumelana nokushisa okuphezulu kwebhodlela lewayini kungenza lokhu kuntuleka. ;
Okwesihlanu, nakuba ipulasitiki (isakhiwo: i-synthetic resin, i-plasticizer, stabilizer, colorant) ukugcwaliswa kwebhodlela kungabonakali ekukhanyeni, kunokumelana okuqinile kwe-oxidation, ukuvala uphawu okungalungile, futhi kulula ukuphuma futhi kubangele ukuwohloka. Ibhodlela lengilazi linomoya oqinile kanye nokuzinza kwamakhemikhali okuhle kakhulu, futhi lingagcina ukunambitheka kwemikhiqizo yotshwala isikhathi eside. Lena inzuzo engenakuqhathaniswa yanoma yiluphi uhlobo lwesiqukathi.
