Xa sithenga ukutya okukhenkcezisiweyo kunye nokutsha kwiivenkile ezinkulu, sihlala sinikela ingqalelo kwiileyibhile kwiimveliso. Iileyibhile zokutya zinokubonisa ngokwenene iimpawu zabo kunye nezalathi zokhuseleko. Iileyibhile zokutya ezisesikweni nezisemthethweni zikhusela impilo nokhuseleko lwabathengi ukusa kumlinganiselo othile. Ke ngoko, ukukhetha ukutya okunomkhenkce okufanelekileyo okuzincamathelisayo linyathelo elibaluleke kakhulu.
Ukuba umtsha kwishishini lokutya elinomkhenkce kwaye sele ukhethe ukupakisha okumnandi kwiziphako zakho ezikhenkcezisiweyo, lixesha lokucinga malunga neeleyibhile ozibekayo kwiimveliso zakho. IiHashtag ziyinxalenye ebalulekileyo yesicwangciso sakho soshishino. Kuba iilebhile ziqulethe ulwazi olubalulekileyo malunga nemveliso yakho ngelixa usenza imveliso yakho ibe nomtsalane ngakumbi kubathengi.
Kweli nqaku, siza kwazisa ubukhulu becala iimpawu ezimele ukuba nazo iilebhile zokutya okukhenkcezisiweyo kunye neemfuno zokuleyibhile.
Ziziphi iileyibhile zesincamathelisi sokutya okuQinisiweyo?
Ukutya okukhenkcezisiweyo okuzincamathelisayo, ekwaziwa njengeeleyibhile ezixhathisa ubushushu obuphantsi okanye iileyibhile zobushushu obuphantsi, zisetyenziswa ikakhulu kwiindawo ezisezantsi zobushushu obuphantsi njengefriji, umkhenkce, ubushushu obuphantsi kakhulu, initrogen engamanzi, njl.
Iileyibhile zokutya ezikhenkcezisiweyo zenziwe ikakhulu ngekhadibhodi yeglasi, iphepha le-thermal, iphepha elisele, njl. Ezi zixhobo zinomsebenzi obalaseleyo wokubopha ubushushu obuphantsi, ukuxhathisa okunamandla kwamanzi, kunye nokusebenza okuqinileyo kokubambisana kwi-PP kunye nefilimu yokutya ye-PE, kwaye ingasetyenziswa ngokubanzi kwiileyibhile zomxholo kunye neelebhile zexabiso zokutya okukhenkcezisiweyo okanye iziselo.
Iimpawu zeempawu zobushushu obuphantsi
Ukutya okukhenkcezisiweyo kubhekiselele kukutya okunemathiriyeli ekrwada yokutya esele ilungisiwe ngokufanelekileyo, emkhenkceni kubushushu be -30 Izidanga zeCelsius, kwaye igcinwe kwaye isasazwe e -18 iidigri zeCelsius okanye ngaphantsi emva kokupakishwa. Ngenxa yobushushu obuphantsi bokugcinwa kwetsheyini ebandayo kuyo yonke le nkqubo, ukutya okukhenkcezisiweyo kuneempawu zobomi obude beshelufu, ayinakonakala, kunye nokusetyenziswa okufanelekileyo, kodwa ikwabeka imiceli mngeni emikhulu kunye neemfuneko eziphezulu zezinto zokupakisha kunye nezixhobo zokuleyibheli.
Ngenxa yokufuma okuphezulu kunye nobushushu obuphantsi kwindawo yokugcina ukutya okukhenkcezisiweyo, kulula ukuyikhubaza, imibimbi, kwaye siwe ukuba iilebhile eziqhelekileyo zisetyenziswa kwindawo yokugcina ebandayo. Iileyibhile ezikhethiweyo kwindawo enjalo kufuneka zikwazi ukuba nobungqina obuhle bokufuma kunye neempawu zokumelana nobushushu obuphantsi.
Iileyibhile zokuzincamathelisa ezizincamathelisayo ngokuqhelekileyo zisebenzisa iilebhile ezizincamathelisayo ezikhethekileyo, kunye nephepha eligqunyiweyo alikhuthazwa. Ukuba iileyibhile ezikhenkcezisiweyo kufuneka zincanyathiselwe kwiimveliso zenyama kwaye zihanjiswe kwikhonkco elibandayo, iileyibhile zephepha zokwenziwa ezikwaziyo ukumelana neoli, amanzi, amanzi, kunye nobushushu obuphantsi kufuneka kukhethwe
Isishwankathelo, iileyibhile ezinobushushu obuphantsi kufuneka zibe nezi mpawu zilandelayo:
1. I-glue ine-viscosity enhle kwaye iyakwazi ukugcina ukuwa;
2. Ukugcinwa kwe-inki okugqwesileyo, umxholo oshicilelweyo akukho lula ukuwucima;
3. Ubungqina bokufuma, into evikela amanzi, kunye neoli-ubungqina.
Indlela yokuncamathelisa ileyibhile yokutya okukhenkcezisiweyo?
Ukuba ileyibhile ijijekile, namadyungudyungu, okanye incamatheliswe ngokugoso, iya kunika abathengi umbono wokuqala wokuba yimveliso eneziphene. Ngokwemvelo, abayi kuthenga iimveliso ezingafanelekanga. Ke ngoko, kubaluleke ngakumbi ukuncamathelisa ileyibhile engumkhenkce.
Siyazi ukuba iglu yoshicilelo oluncamathelayo luhlala lukwazi ukusebenzisa ngokupheleleyo i-viscosity yayo kubushushu begumbi.. Kwindawo yobushushu obuphantsi, ubumanzi beglu iya kuncipha, kubangela ukuba i-viscosity yeglue yehle ngokukhawuleza, nto leyo eya kuchaphazela eyona siphumo sokuleyibhelishwa. Xa uleyibhile kwindawo yobushushu obuphantsi, i-adhesives eqhelekileyo iya kuba nzima kwaye i-brittle ukwenzela ukuba i-viscosity iya kuncitshiswa kakhulu. Ukwengeza, kunokubakho ukufuma okanye iqabaka kumphezulu wento eza kubhalwa kwindawo yobushushu obuphantsi., nto leyo ekwanyusa ubunzima bophawulo. Ke ngoko, ukuleyibhelishwa kwindawo yobushushu obuphantsi ayilovavanyo lokuncamathelisa kuphela kodwa ikwabeka iimfuno ezingqongqo kumanzi kunye nokukrazuka kwezinto ezingaphezulu..
Iglu esisiseko sokuncamathelisa ileyibhile ayikwazi ukuhlangabezana neemfuno zokusetyenziswa kweelebhile zamatsheyini abandayo, ke iilebhile ezininzi kwindawo yokugcina ebandayo ziya kusebenzisa iglu yobushushu obuphantsi. Uphawu lolu hlobo lweglue kukuba lusenokugcina i-viscosity ezinzileyo kwindawo yobushushu obuphantsi., kwaye inokuhlangabezana neemfuno zokuleyibhile zeileyibhile zamatsheyini abandayo kwindawo yobushushu obuphantsi.
Ukuba ileyibhile incamathelisiwe kwiqondo lobushushu begumbi kwaye emva koko ibekwe kwindawo yokugcina ebandayo, iphepha eliphezulu leleyibhile kufuneka likhethwe nge-elasticity ethile. Kuba ifom yokupakisha yento inokuba yipakethe eqhelekileyo yephepha okanye ingxowa yenayiloni., iilebhile zezinto ezahlukeneyo zingakhethwa ngokweemfuno.
Ngoku, iqondo eliphantsi lobushushu beglu iileyibhile zekhonkco elibandayo ezineendleko eziphezulu zisetyenziswa ikakhulu kumashishini akumgangatho ophezulu afana nezitofu zokugonya.. Uninzi lokutya, imithwalo, kunye namashishini othutho asebenzise indlela yokubeka ibhokisi yokupakisha yangaphandle kwiqondo lobushushu begumbi 24 iiyure emva kokuba uyilebhile, kwaye emva koko ukupakisha kwindawo yobushushu obuphantsi emva kokuba ileyibhile isebenzise ngokupheleleyo i-viscosity yayo..
Usetyenziso lwezamayeza lweeLeyibhile zokuQinisa
Iileyibhile zobushushu obuphantsi azisetyenziswa kuphela ekupakishweni kokutya okunomkhenkce, kodwa nakwintsimi yamayeza.
Iileyibhile zonyango zihlala zigcinwa kwaye zithunyelwe kwindawo yobushushu obuphantsi. Kuba izitofu ezininzi zokugonya kufuneka zibe kwindawo yobushushu obuphantsi ngexesha lemveliso, yokugcina, kunye nenkqubo yothutho, kuyimfuneko ukukhetha iileyibhile ezikhethekileyo zephepha lokuzincamathela ukuze ubhale, ezibizwa ngokuba ziileyibhile zekhonkco elibandayo.
Umphezulu wolu hlobo lweleyibhile iprintwa nge-inki yesivamvo sobushushu. Emva kokutshintsha kobushushu be-ambient, ngokubanzi, umbala we-inki uya kutshintsha ngokungenakuguquleka xa ubushushu buphakama. Iithegi ezinjalo zinomsebenzi wokubona utshintsho kwiqondo lokushisa eliphakathi. Ke ngoko, yonke inkqubo yokuvelisa kunye nokusetyenziswa okulandelayo kufuneka kuqhutywe kwindawo yobushushu obuphantsi.
Ukuba uneemfuno zelebhile yesiko kunye nemibuzo, Nceda ungathandabuzi ukuqhagamshelana neqela lethu ukuze ufumane iingcebiso zobungcali.
