III. Uyilo lwesakhiwo seekomityi zephepha
A. Iteknoloji yokwambathisa yangaphakathi yeekomityi zephepha
1. Ukuphuculwa kokuthintela amanzi kunye neempawu zokugquma
Itekhnoloji yokwambathisa yangaphakathi yenye yezoyilo eziphambili zeekomityi zephepha, ezinokuthi ziphucule ukungeniswa kwamanzi kunye nokusebenza kwe-thermal insulation yeekomityi.
Kwimveliso yekomityi yemveli yephepha, umaleko we-polyethylene (PE) yokugqoka idla ngokusetyenziswa ngaphakathi kwendebe yephepha. Le ngubo inokusebenza okulungileyo kokungena kwamanzi. Inokuthintela ngokufanelekileyo ukuba iziphuzo zingene ngaphakathi kwikomityi yephepha. Kwaye inokuthintelaindebe yephephaukusuka ekukhubazeni nasekuqhekekeni. Kwangaxeshanye, ukutyabeka kwe-PE kunokubonelela ngempembelelo ethile yokugquma. Inokuthintela abasebenzisi ukuba bazive ubushushu obuninzi xa bephethe iikomityi.
Ukongeza kwi-PE yokwambathisa, kukwakho nezinye izinto ezintsha zokugquma ezisetyenziswa kakhulu kwiikomityi zephepha. Ngokomzekelo, i-polyvinyl alcohol (PVA) yokugqoka. Inokumelana kakuhle namanzi kunye nokumelana nokuvuza. Ngoko ke, inokugcina ingaphakathi lekomityi yephepha yomile. Ukongeza, i-polyester amide (PA) yokugquma inokukhanya okuphezulu kunye nokusebenza kokutywinwa kobushushu. Inokuphucula umgangatho wokubonakala kunye nokusebenza kokutywinwa kobushushu kwiikomityi zephepha.
2. Isiqinisekiso soKhuseleko lokutya
Njengesitya esisetyenziselwa ukubamba ukutya kunye neziselo, izinto zokugquma zangaphakathi zeekomityi zephepha kufuneka zihambelane nemigangatho yokhuseleko lokutya. Oku kuqinisekisa ukuba abantu banokuyisebenzisa ngokukhuselekileyo.
Isixhobo sokugquma sangaphakathi kufuneka singene kwisatifikethi esifanelekileyo sokhuseleko lokutya. Okufana ne-FDA (i-Food and Drug Administration) isatifikethi, i-EU yokuqinisekisa ukutya kunye ne-EU, njl. Ezi ziqinisekiso ziqinisekisa ukuba izinto zokugquma ngaphakathi kwendebe yephepha azibangeli ukungcoliswa kokutya kunye neziphuzo. Kwaye kuyafuneka ukuba kuqinisekiswe ukuba azikhuphi izinto ezinobungozi, ziqinisekisa impilo kunye nokhuseleko lwabasebenzisi.
B. Uyilo olukhethekileyo lwesakhiwo seekomityi zephepha
1. Uyilo lokuqinisa ezantsi
Uyilo lokuqinisa olusezantsi lweindebe yephephakukuphucula amandla okwakhiwa kwekomityi yephepha. Oku kunokuthintela indebe yephepha ekuweni ngexesha lokuzaliswa kunye nokusetyenziswa. Kukho iindlela ezimbini eziqhelekileyo zokuqiniswa kwezantsi eziqhelekileyo: i-bottom edibeneyo kunye nezantsi eqinisiweyo.
Ukusonga phantsi kuyilo olwenziwe kusetyenziswa inkqubo ethile yokugoqa phantsi kwendebe yephepha. Iileya ezininzi zamaphepha zitshixiwe kunye ukwenza ubume obuqinileyo bomzantsi. Oku kuvumela indebe yephepha ukuba imelane nomlinganiselo othile wobunzima kunye noxinzelelo.
I-bottom eyomeleziweyo luyilo olusebenzisa izinto ezikhethekileyo okanye izinto eziphantsi kwendebe yephepha ukwandisa amandla okwakhiwa. Umzekelo, ukwandisa ubukhulu bomzantsi wekomityi yephepha okanye ukusebenzisa izinto zephepha ezomeleleyo. Ezi zinokuphucula ngokufanelekileyo amandla asezantsi ekomityi yephepha kunye nokuphucula ukuxhathisa koxinzelelo.
2. Ukusetyenziswa kwesiphumo sesikhongozeli
Iikomityi zephepha zihlala zipakishwe kwizikhongozeli ngexesha lokuthuthwa nokugcinwa. Oku kunokonga indawo kunye nokuphucula ukusebenza kakuhle. Ngoko ke, ezinye iiplani ezikhethekileyo zesakhiwo zisetyenziselwa iikomityi zephepha. Oku kunokufikelela kwisiphumo esingcono sesikhongozeli.
Umzekelo, uyilo lwecaliber yekomityi yephepha lunokwenza umphantsi wendebe ugubungele phezulu kwikomityi yephepha elandelayo. Oku kwenza kube lula ukuba iikomityi zephepha zihlangane kwaye zonge indawo. Ukongeza, uyilo olufanelekileyo lobude kunye nomlinganiselo wedayamitha yeekomityi zephepha nako kunokuphucula uzinzo lokupakishwa kwekomityi yephepha. Oku kunokuphepha iimeko ezingazinzanga ngexesha lenkqubo yokupakisha.
Itekhnoloji yokwambathisa yangaphakathi kunye noyilo olukhethekileyo lwesakhiwo seekomityi zephepha linokuphucula ukusebenza kunye nokusebenza kwazo. Ngokuqhuba izinto ezintsha kunye nokuphuculwa, iikomityi zephepha zinokuhlangabezana ngcono neemfuno zabantu zemathiriyeli yoqhagamshelwano lokuTya. Ngaphezu koko, inokubonelela ngamava akhuselekileyo, afanelekileyo, kunye nokusingqongileyo komsebenzisi.
