Iingxowa zokufunxa ukutya kufuneka zibe yindlela onokukhetha ngayo

Ubomi iingxowa zokupakisha ukutya ezingenantosingabona yonke indawo, Iingxowa zokucoca ulwelo ekukhetheni nasekusebenziseni izinto kunye neemfuno zombala wazo, namhlanje ndiza kuchaza indlela yokukhetha ingxowa ye-vacuum yokutya.

1: iingxowa ze-vacuum zahlulwe zibe ngumaleko omnye kunye nomaleko omninzi

Eziqhelekileyo iingxowa zokucoca ulwelo Kwizinto ze-PE ezineleya enye, ezo ngxowa zinokucocwa nge-vacuum, kodwa izinga lokuphuka kwe-vacuum kunye nezinga lokuvuza komoya liphezulu, kodwa ixabiso liphantsi, kukho abathengi abaninzi ukuze bonge iindleko ngokukhetha umaleko omnye weengxowa ze-PE njengengxowa ye-vacuum oza kuzisebenzisa. Iingxowa ze-vacuum ezilungileyo zizinto ezidityanisiweyo ezineleya ezininzi, ezifana: i-nylon / i-PE, le yingxowa ye-composite eneleya ezimbini, ingxowa enamandla kakhulu, ayinanto ayizukuvuza, uninzi lweengxowa zokupakisha ukutya ezikhoyo ngoku zikhethwe njengeengxowa ezidityanisiweyo ezinamalayelo amaninzi. ingxowa yokufunxa ulwelo.

2: ubukhulu bezinto kunye neempawu ezikhethekileyo zokukhethwa kwezinto

Ukulayisha ukutya okwahlukileyo kufuneka ukhethe ubukhulu obahlukeneyo kunye neempawu ezahlukeneyo ze izixhobo zengxowa yokucoca ulwelo, ezigcwele iimveliso ezinzima kufuneka zikhethe izinto ezixineneyo, ezigcwele iimveliso ezilula ukukhetha izinto ezincinci ukonga iindleko. Kakade ke, okukhona izinto zityebile, kokukhona ixabiso liphezulu, kodwa zikwanamandla. Ukutya okwahlukeneyo kuya kuba neempawu ezahlukeneyo, umzekelo: ioyile yokutya ebhakiweyo ngetyuwa ukukhetha izinto ezimelana neoyile, ityuwa yokutya eyosiweyo ephezulu ukukhetha izinto ezimelana neasidi kunye ne-alkali, imfuneko yokubulala iintsholongwane kubushushu obuphezulu okanye iimveliso zokupheka kubushushu obuphezulu ukukhetha izinto ezimelana nobushushu obuphezulu.

Kwimveliso yeengxowa kufuneka baziswe ngeemfuno zabavelisi beengxowa, ezithwele iimveliso, iimveliso ezineemfuno ezikhethekileyo, njl., ukuze baqonde iinkcukacha ezithile zingenziwa ngokwezifiso ukuze ziphume kwiingxowa zemveliso ukuze kuthintelwe ukusetyenziswa kwenkqubo yengxaki eyenzekayo.
