Uma sithenga ukudla okuqandisiwe nokusha ezitolo ezinkulu, sivame ukunaka amalebula emikhiqizweni. Amalebula okudla angabonisa ngempela izibaluli zabo nezinkomba zokuphepha. Amalebula okudla asemthethweni nasemthethweni avikela impilo nokuphepha kwabathengi bethu ngokwezinga elithile. Ngakho-ke, ukukhetha ilebula efanele yokudla okufriziwe okunamathelayo kuyisinyathelo esibaluleke kakhulu.
Uma umusha embonini yokudla okuqandisiwe futhi usuvele ukhethe ukupakisha okuphambili kokuphatha kwakho okufriziwe, sekuyisikhathi sokucabanga ngamalebula owafaka emikhiqizweni yakho. Ama-Hashtag ayingxenye ebalulekile yesu lakho lebhizinisi. Ngoba amalebula aqukethe ulwazi olubalulekile mayelana nomkhiqizo wakho kuyilapho enza umkhiqizo wakho ukhange nakakhulu kubathengi.
Kulesi sihloko, sizokwethula ikakhulukazi izici okufanele amalebula okudla okufriziwe abe nazo kanye nezidingo zokulebula.
Ayini Amalebula Esitikha Sokudla Okuqandisiwe?
Amalebula okudla okuqandisiwe okunamathelayo, aziwa nangokuthi amalebula amelana nezinga lokushisa eliphansi noma amalebula ezinga lokushisa eliphansi, zisetshenziswa kakhulu ezindaweni ezinezinga lokushisa eliphansi elingaphansi kweqanda njengeziqandisi, ukuqanda, Izinga lokushisa eliphansi kakhulu, i-nitrogen ewuketshezi, njll.
Amalebula okudla okuqandisiwe enziwa ikakhulukazi ngekhadibhodi engilazi, iphepha elishisayo, iphepha le-offset, njll. Lezi zinto zinokusebenza okuhle kakhulu kwe-low-temperature bonding, ukumelana kwamanzi okuqinile, kanye nokusebenza okuqinile kwesibopho ku-PP kanye nefilimu yokudla ye-PE, futhi ingasetshenziswa kakhulu kumalebula okuqukethwe kanye namalebula amanani okudla okufriziwe noma iziphuzo.
Izici zamalebula wezinga lokushisa eliphansi
Ukudla okuqandisiwe kubhekisela ekudleni okunempahla yokusetshenziswa efanelekile ecutshungulwe kahle, iqhwa ezingeni lokushisa -30 amadigri Celsius, futhi igcinwe futhi isatshalaliswe ku -18 amadigri Celsius noma aphansi ngemva kokupakisha. Ngenxa yezinga lokushisa eliphansi lokugcinwa kweketango elibandayo kuyo yonke inqubo, ukudla okuqandisiwe kunezici zeshalofu ende, engaboli, nokusetshenziswa esikahle, kodwa futhi kubangela izinselele ezinkulu kanye nezidingo eziphakeme zezinto zokupakisha nezinto zokulebula.
Ngenxa yomswakama ophezulu kanye nezinga lokushisa eliphansi endaweni yokugcina ukudla okufriziwe, kulula ukukhubazeka, ukushwabana, futhi siwe uma amalebula ajwayelekile esetshenziswa endaweni ebandayo. Amalebula akhethiwe endaweni enjalo kufanele akwazi ukuba nezici ezinhle zokuvikela umswakama kanye nezici zokumelana nezinga lokushisa eliphansi.
Amalebula azinamathiselayo aqandayo ngokuvamile asebenzisa amalebula akhethekile azinamathiselayo, futhi iphepha eliboshwe alinconywa. Uma amalebula afriziwe kufanele anamathiselwe emikhiqizweni yenyama futhi athuthwe ngeketango elibandayo, amalebula ephepha okwenziwa amelana nowoyela, amanzi, amanzi, futhi izinga lokushisa eliphansi kufanele likhethwe
Ngokufigqiwe, amalebula ezinga lokushisa eliphansi adinga ukuba nezici ezilandelayo:
1. Iglue ine-viscosity enhle futhi ingagcina ingawi;
2. Ukugcinwa kwe-inki okuhle kakhulu, okuqukethwe okuphrintiwe akulula ukukusula;
3. Ukufaka umswakama, ukungena kwamanzi, kanye nokuvikela amafutha.
Indlela yokunamathisela ilebula yokudla okuqandisiwe?
Uma ilebula isontekile, namabhamuza, noma kunamathiselwe ngokugwegwile, izonikeza amakhasimende umbono wokuqala wokuthi iwumkhiqizo onesici. Ngokwemvelo, ngeke bathenge imikhiqizo engafanelekile. Ngakho-ke, kubaluleke kakhulu ukunamathisela ilebula efriziwe.
Siyazi ukuthi i-glue yokuphrinta okunamathelayo ngokuvamile ikwazi ukusebenzisa ngokugcwele i-viscosity yayo ekamelweni lokushisa.. Endaweni enezinga lokushisa eliphansi, i-fluidity yeglue izokwehla, okwenza i-viscosity yeglue yehle kakhulu, okuzothinta umphumela wangempela wokulebula. Uma ulebula endaweni enezinga lokushisa eliphansi, ama-adhesives ajwayelekile azoba lukhuni futhi abe brittle ukuze i-viscosity iyancipha kakhulu. Ngaphezu kwalokho, kungase kube nomswakama noma ngisho nesithwathwa phezu kwento okumele ibhalwe endaweni enezinga lokushisa eliphansi, okwandisa nobunzima bokulebula. Ngakho-ke, ukulebula endaweni enezinga lokushisa eliphansi akuyona nje isivivinyo se-adhesive kodwa futhi kubeka izidingo eziqinile mayelana nokumelana kwamanzi nokudabula kwezinto ezingaphezulu..
Iglue yelebula enamathelayo eyisisekelo ayikwazi ukuhlangabezana nezidingo zohlelo lokusebenza zamalebula amaketanga abandayo, ngakho-ke amalebula amaningi endaweni ebandayo azosebenzisa iglue yobuchwepheshe enezinga lokushisa eliphansi. Isici salolu hlobo lweglue ukuthi isengakwazi ukugcina i-viscosity ezinzile endaweni enezinga lokushisa eliphansi., futhi ingahlangabezana nezidingo zokulebula zamalebula eketango elibandayo endaweni enezinga lokushisa eliphansi.
Uma ilebula inanyathiselwa ezingeni lokushisa elilingana negumbi bese ifakwa endaweni yokugcina ebandayo, iphepha elingaphezulu lelebula kufanele likhethwe ngokunwebeka okuthile. Njengoba ifomu lokupakisha lento lingase libe ukupakishwa kwephepha okujwayelekile noma ukupakishwa kwesikhwama senayiloni., amalebula wezinto ezahlukene angakhethwa ngokwezidingo.
Okwamanje, I-low-temperature glue ye-cold chain amalebula anezindleko eziphezulu asetshenziswa kakhulu ezimbonini ezisezingeni eliphezulu njengemithi yokugoma. Iningi lokudla, impahla, kanye nezimboni zezokuthutha zisebenzisa indlela yokubeka ibhokisi lokupakisha langaphandle ekamelweni lokushisa ukuze 24 amahora ngemva kokulebula, bese uyayipakisha endaweni enezinga lokushisa eliphansi ngemuva kokuthi ilebula isebenzise i-viscosity yayo ngokugcwele.
Izicelo Zemithi Yamalebula Okuqandisa
Amalebula okushisa aphansi awasetshenziswa kuphela ekufakweni kokudla okufriziwe, kodwa nasemkhakheni wemithi.
Amalebula ezokwelapha ngokuvamile agcinwa futhi athunyelwe endaweni enezinga lokushisa eliphansi. Ngoba imithi eminingi yokugoma idinga ukuba endaweni enezinga lokushisa eliphansi ngesikhathi sokukhiqiza, isitoreji, kanye nenqubo yezokuthutha, kuyadingeka ukukhetha amalebula ephepha akhethekile anamathelayo okulebula, ngokuvamile abizwa ngokuthi amalebula e-cold chain.
Ingaphezulu lalolu hlobo lwelebula liphrintwa ngoyinki wenzwa yokushisa. Ngemva kokushintsha kwezinga lokushisa elizungezile, ngokuvamile, umbala weyinki uzoshintsha ngendlela engenakuhlehliswa lapho izinga lokushisa likhuphuka. Omaka abanjalo banomsebenzi wokuthola izinguquko kuzinga lokushisa elizungezile. Ngakho-ke, yonke inqubo yokukhiqiza kanye nokusetshenziswa okulandelayo kufanele kwenziwe endaweni enezinga lokushisa eliphansi.
Uma unezidingo zelebula ngokwezifiso kanye nemibuzo, sicela ungangabazi ukuxhumana nethimba lethu ukuze uthole iseluleko sochwepheshe.
