Iingxowa ezikwaziyo ukumelana nobushushu obuphezulu zineempawu zokupakisha ezihlala ixesha elide, indawo yokugcina ezinzileyo, ukulwa neentsholongwane, unyango lokubulala iintsholongwane kubushushu obuphezulu, njl.njl., kwaye zizinto ezifanelekileyo zokupakisha ezidityanisiweyo. Ngoko ke, zeziphi izinto ezibalulekileyo ekufuneka ziqwalaselwe ngokwesakhiwo, ukukhethwa kwezinto, kunye nobugcisa? Umenzi wokupakisha onobuchule oguquguqukayo iPACK MIC uza kukuxelela.
Ulwakhiwo kunye nokukhethwa kwezinto zebhegi yokuzibamba enganyangekiyo kubushushu obuphezulu
Ukuze kuhlangatyezwane neemfuno zokusebenza kweengxowa ezikwaziyo ukumelana nobushushu obuphezulu, umaleko wangaphandle wesakhiwo wenziwe ngefilimu yepolyester enamandla aphezulu, umaleko ophakathi wenziwe ngefoyile ye-aluminium eneempawu zokukhusela ukukhanya kunye nokungena komoya, kwaye umaleko wangaphakathi wenziwe ngefilimu ye-polypropylene. Ulwakhiwo olunemigangatho emithathu luquka i-PET/AL/CPP kunye ne-PPET/PA/CPP, kwaye ulwakhiwo olunemigangatho emine luquka i-PET/AL/PA/CPP. Iimpawu zokusebenza zeentlobo ezahlukeneyo zeefilimu zezi zilandelayo:
1. Ifilimu yeMylar
Ifilimu yepolyester inamandla aphezulu oomatshini, ukumelana nobushushu, ukumelana nokubanda, ukumelana neoyile, ukumelana neekhemikhali, umqobo wegesi kunye nezinye iimpawu. Ubukhulu bayo yi-12um /12microns kwaye ingasetyenziswa.
2. Ifoyile yealuminiyam
Ifoyile ye-aluminiyam inomqobo ogqwesileyo wegesi kunye nokumelana nokufuma, ngoko ke kubaluleke kakhulu ukugcina incasa yokuqala yokutya. Ukhuseleko oluqinileyo, okwenza iphakheji ingachaphazeleki kakhulu ziibhaktheriya kunye nomngundo; imo ezinzileyo kumaqondo obushushu aphezulu naphantsi; ukusebenza kakuhle komthunzi, amandla okubonakalisa aqinileyo obushushu nokukhanya. Ingasetyenziswa ngobukhulu be-7 μm, inemingxuma embalwa kangangoko kunokwenzeka, kunye nomngxuma omncinci kangangoko kunokwenzeka. Ukongeza, ukuthamba kwayo kufuneka kube kuhle, kwaye umphezulu kufuneka ungabi namabala eoyile. Ngokubanzi, iifoyile ze-aluminiyam zasekhaya azikwazi ukuhlangabezana neemfuno. Abavelisi abaninzi bakhetha imveliso yeefoyile ze-aluminiyam zaseKorea nezaseJapan.
3. Inayiloni
I-nylon ayinazo nje kuphela iimpawu ezintle zokuthintela, kodwa ayinavumba, ayinancasa, ayinatyhefu, kwaye iyakwazi ukumelana nokubhoboza. Inobuthathaka bokuba ayimelani nokufuma, ngoko ke kufuneka igcinwe kwindawo eyomileyo. Nje ukuba ifunxe amanzi, izalathiso zayo ezahlukeneyo zokusebenza ziya kuncipha. Ubukhulu be-nylon yi-15um (15microns). Ingasetyenziswa ngoko nangoko. Xa ilaminate, kungcono ukusebenzisa ifilimu elaminate emacaleni amabini. Ukuba ayilofilimu elaminate emacaleni amabini, icala layo elinganyangwanga kufuneka lifakwe i-laminate nge-aluminium foil ukuqinisekisa ukuba iqinile.
4. I-Polypropylene
Ifilimu yePolypropylene, izinto ezingaphakathi zeengxowa ezimelana nobushushu obuphezulu, ayifuni nje kuphela ukuba ithambe kakuhle, kodwa ikwaneemfuno ezingqongqo kumandla ayo okutsalwa, amandla okuvala ubushushu, amandla okuchaphazeleka kunye nokwandiswa ngexesha lokuphumla. Zimbalwa iimveliso zasekhaya ezinokuhlangabezana neemfuno. Isetyenziswa, kodwa isiphumo asisihle njengezinto ezikrwada ezingenisiweyo, ubukhulu bayo buyi-60-90microns, kwaye ixabiso lonyango lomphezulu lingaphezulu kwe-40dyn.
Ukuze kuqinisekiswe ngcono ukhuseleko lokutya kwiingxowa zokuphendula ezishushu kakhulu, iphakheji ye-PACK MIC yazisa ngeendlela ezi-5 zokuhlola ukupakisha apha:
1. Uvavanyo lokungabi namoya kwingxowa yokupakisha
Ngokusebenzisa umoya ocinezelweyo kunye nokukhupha amanzi phantsi kwamanzi ukuvavanya ukusebenza kokuvala kwezinto, ukusebenza kokuvala kweengxowa zokupakisha kunokuthelekiswa ngempumelelo kwaye kuvavanywe ngovavanyo, olubonelela ngesiseko sokumisela izalathisi zobugcisa ezifanelekileyo zemveliso.
2. Ukumelana noxinzelelo lwengxowa yokupakisha, ukusebenza kokumelana nokuwauvavanyo.
Ngokuvavanya ukumelana noxinzelelo kunye nokusebenza kokumelana nokuwa kwengxowa yokujija enganyangekiyo kubushushu obuphezulu, ukusebenza kokumelana nokuqhekeka kunye nomlinganiselo ngexesha lenkqubo yokutshintsha kunokulawulwa. Ngenxa yemeko etshintsha rhoqo kwinkqubo yokutshintsha, uvavanyo loxinzelelo lwephakheji enye kunye novavanyo lokwehla kwebhokisi yonke yeemveliso lwenziwa, kwaye uvavanyo oluninzi lwenziwa kwiindlela ezahlukeneyo, ukuze kuhlalutywe ngokupheleleyo ukusebenza koxinzelelo kunye nokuwa kweemveliso ezipakishiweyo kunye nokusombulula ingxaki yokusilela kwemveliso. Iingxaki ezibangelwa kukupakisha okonakeleyo ngexesha lokuthuthwa okanye lokuhamba.
3. Uvavanyo lwamandla oomatshini lweengxowa zokuziphendulela zobushushu obuphezulu
Amandla oomatshini ezinto zokupakisha aquka amandla okuxobuka adibeneyo ezinto, amandla okutywina ubushushu bokuvala, amandla okutsalwa, njl. Ukuba isalathisi sokufumanisa asikwazi ukuhlangabezana nomgangatho, kulula ukuphula okanye ukwaphuka ngexesha lenkqubo yokupakisha nokuthutha. Umvavanyi wokutsalwa wendalo yonke ungasetyenziswa ngokwemigangatho efanelekileyo yesizwe neyeshishini, kunye neendlela ezisemgangathweni zokufumanisa nokufumanisa ukuba iyafaneleka na okanye akunjalo.
4. Uvavanyo lokusebenza komqobo
Iingxowa zokuzibamba ezingatshisi kakhulu zidla ngokupakishwa ngezinto ezinesondlo esininzi ezifana neemveliso zenyama, ezithi zinyibilike lula kwaye zonakale. Nokuba zigcinwe ixesha elide, incasa yazo iya kwahluka ngokwemihla eyahlukileyo. Ukuze ufumane umgangatho, kufuneka kusetyenziswe izinto ezithintelayo, kwaye ke ngoko kufuneka kwenziwe uvavanyo oluqinileyo lwe-oksijini kunye nokufuma kwizinto zokupakisha.
5. Ukufunyanwa kwesinyibilikisi esiseleyo
Ekubeni ukuprinta nokudibanisa izinto zizinto ezimbini ezibalulekileyo kwinkqubo yokupheka eshushu kakhulu, ukusetyenziswa kwe-solvent kuyimfuneko kwinkqubo yokuprinta nokudibanisa izinto. I-solvent yikhemikhali ye-polymer enevumba elithile elibi kwaye iyingozi emzimbeni womntu. Izixhobo, imithetho kunye nemigaqo yangaphandle inezalathisi zolawulo olungqongqo kwezinye zezinyibilikisi ezifana ne-toluene butanone, ngoko ke iintsalela ze-solvent kufuneka zifunyanwe ngexesha lenkqubo yokuvelisa iimveliso ezigqityiweyo, iimveliso ezigqityiweyo ezihlanganisiweyo kunye neemveliso ezigqityiweyo ukuqinisekisa ukuba iimveliso zisempilweni kwaye zikhuselekile.
