Ukubona Izizima Ze-Heat-Tunnel Ngokuphepha Ukugcina Kwesipakethi
Emhlabeni onjengamandla wokupaka, ukufinyelela kumgciniko wesiphakamiso esihle kudinga ukuhleleka kwezinklingo zemali nezinhloso eziphumelelayo. Ingqikithi phakathi kwe isinkhomo esisebenza ubude bendawo nesimiso sezilimi zokuphefumula kudala indima eyisisekelo ekwenzeni amaphaki aphunyelwe ngendlela efanelekileyo ephatha izinto njalo kungakhathalwa kuhlaza. Leli gaba elijwayelekile lilondoloza ubuningi bezinkinga zezinklingo zemali ezahlukene, ukuqinisekisa ukuthi kusiphakamise kahle futhi kugcine izinkinga ezifana nokugcwala, ukuvulwa okungafanelekile, noma ukuphunyelwa okungakazali.
Imisebenzi yesipakethe samanje iyaphantsi kakhulu kuteknoloji yeshirinki ikwezi ukwakha iziqhathaniso zezinhlekelelo, zigcine, kanye nezobuchwepheshe. Umrhuba wale miyalo kusohlala kuzinzile kukuqinisekiswa kwezimpawu zempilo eziphathelene nesilinganiso sefilimu, isivinini, kanye nezimo zomphakathi. Ukuziqonda lezi zinkinga kuyakhe kakhulu ukufinyelela emipheleni enjalo, enobunkemkani obungcono kuqhawekanga isipakethe.
Ukuzinza Kwezinhlayiya Zokubandakanya KweShrink Film Nokuziphatha
Isakhiwo SeChemistry Nezinhlayiya Zokugcwalisa
Ishrink film inguqulelo yezinhlayiya ezihlelekileyo ezibalwe ukuthi zizime ngemva kokuthi kutholakala emthwini wethempurayhaya. Isakhiwo semoyileli yalezi zinhlayiya kusenhlaleni izixhumanisi ezilandelanayo ezingashiyi ngemva kokugcwalisa, kuvumela ifilimu ukubuya ekaleni lakhe ngaphambi kokuthintwa. Lokhu okuphathelene nokuzinza kwemoyileli, kukho okunikeza ishrink film amandla akhethekile yokupaki.
Izinhlalo ezahlukeneyo zezinhlayiya zizimela ngendlela eyahlukene ngemva kokuthi kutholakala umthwana. Izinhlayiya zokubandakanya zePolyolefin, PVC, ne-polyethylene zinesilinganiso esahlukene sokugcwalisa nesimo sokushizeni. Ukuzinza lezi zinhlayiya zibaluleke kakhulu ekukhetheni izidingo zomthwana wesitolo sezishiza futhi ukuqeda isimo esihle sesipakethe.
Ukungcolana Kwesilinganiso Sekhetha Ngaphezu Kwamathuba Okugcwalisa
Ubukhulu befilimu yesinkwa kubangelisa inzuzo yamandla wokushisa okudingekayo ukuze ishunqwe kahle. Imafili enye emncane kakhulu, ngaphezu kwesikhathi esincane se-50-micron, zidinga isikhathi esincane sokutholwa kweshishini kanye nempilo engaphansi komkhuba ngokulinganisela nezinkimbinkimbi. Ngokuphathelene, imfili ye-100-micron idinga amandla aphezulu wokushisa ukuze ishunqe ngendlela efanayo engakwazi ukudala izindawo ezinzima noma izinkinga.
Ukungena kweshishini phakathi kwezinhlayiya zefilimu kusenzenjalo ngokanda, lokhu kwenza ukulawula kakhulu komkhuba kubaluleke kakhulu. Ukushisa okuningi kungakhiqa noma kudale amathambo, kodwa ukushisa okungafanelekile kuthola iphakethe eliphambene, elibonakala njengobuchwepheshe futhi akwazi ukunikeza ukuphepha okufanele noma ubonakaliso obuhle.
Izigaba zomkhuba ezihle kakhulu zezinye i-thickness zefilimu
Izicwangciso zemfili ye-50-70 Micron
Izihlango lapha ezingaphansi kakhulu zisembenza kahle kunazo ngemithwalo yecaleni phakathi kwe-160-180°C (320-356°F). Lezi zinhlayiya ezincane zidinga ixesha elincane lokuthintana, okwaze kwaziwa phakathi kwezimbili nezintathu. Okulula kulula kule zihlango kukhona ukugcina ubunzima bokuxhumana komoya nempilo yecaleni ngamandla.
Xa usebenzisa izihlango ezinezikhala ezingama-50-70, kubalulekile ukulandela kahle iindlela zecaleni zikalenda. Ezinye izixhobo ezintsayi zineendidi ezininzi ezivumela ukuphefumula nokuncipha okuphindaphindiwe, ukukhokha kwalokho olungafazeka kumongo okungabangela ukungahle kwayo okanye ukuchithakala.
Iziparamitha zeziHlango ezingama-80-100 Micron
Izihlango ezinkulu ngokuvamile zidinga amacala phakathi kwe-180-200°C (356-392°F) naxesha elide kunesithathu nesine sekondi. Lezi zinhlayiya zilungiselelwa yiindlela zokuphefumula eziphindaphindileyo eziphinde ziphinde zibuyisela isihlango ekusebenziseni cala, ukunciphisa umcinga wokuchithakala komthwalo futhi uqiniseke ukuba kushunqwa ngokulinganayo.
Ubunzima obukhulu bezinga lezinto ezinezincwadi ezinde kufanele kube nobubi bempilo ekugcineni ubunye bomoya. Kudingeka ukuba kube nobubi bempilo ngokuphelele emoyeni phakathi kwegalaji, ngoba ukuchazwa okungahle kungathatha isimo esingahle sokushukuma futhi kuthinta ubunzima bezinkawuli.
Izinhloso Zamanje Ezahlukana Ngokwahlukanwa Kwesimo
Ukuzenzakala Kwesimo Somlaba
Isimo samanzi sikhona ngaphandle kusenza isiphazamiso esikhulu emsebenzini walezincwadi zoshukumo nezimali ezingafunekiyo kwegalaji yomoya. Izisevisi ezisebenzayo emasimini amancane angadinga ukulungisa izindleko phezulu ukuze ikhokhele ukuphela komoya, kodwa ezase siminyakeni engcono kungadinga izimali ezincane ukuze kugcinwe ukushukumelwa kabili.
Ukuguqulwa kweminyaka yonke kungabangela isiphazamiso esihlukile emsebenzini walezincwadi zoshukumo, lokhu kwenza kubalulekile ukuthi kutholakale izilungiso ezahlukene ngomnyaka womhla nasebushini. Ukubheka nokulungisa okuhlanjwayo kwezimali kunceda ukugcina isiphazamiso esifanayo ngonyaka wonke.
Ukugcinwa Kwamandla Nezindleko Zomoya
Amathuba okugcwele kuyahlukanisa indlela lefayela yeshrink ibukeka ngishukumisa. Amathuba aphakeme kakhulu angadinga izilungiselelo zokuthepha noma uhlelo olunye lwentonga ukuze kufakwe ishukumisa esihle. Ukuphatha izinhlayiya zenesithuthi kugatsheni kunciphisa ukulayisha kwesithuthi futhi kunciphisa imiphumela.
Izitsha zeshukumisa ezintsha ziwuthinta izici zokuphatha amathuba nokuthutha kwezinhlayiya ezininzi. Le teknoloji iyanciphisa ukuthuthuka kwezimo ngaphandle kwezinkinga zangaphandle, iyenzi imiphumela yokupakiwa ibe yinkinga enezinhla.
Ukulawula Ibhili Nokuxhasa Imiba
Izinkinga Ezihlukene Nezisusa
Ukuzwisisa izinkinga ezihlukene eziphazanyiswa ngexesha lokushukumisa kunciphisa abasebenzisi ukulawula ubume obuphelele. Izinkinga njenge-"dog ears", "fish eyes", noma "ballooning" zanquma izinkinga ezithile ezixhoshelana nethemperetura ezingazange ziqondakale, ezingasolwa ngokulungiselela kahle izilungiselelo zegatshi likhuni.
Ukuhlola ubunzima ngokuthuthukile kanye nokudokolisa izilungiso ezitholakele kwezinhlanhla ezahlukene kanye nezinhlobo zomshini ukwenza umbhalo osetshenziswa kangcono ekugcineni iziphumo. Lokhu kususa kakhulu kwebunzima kunciphisa ukushintshwa kwezinto futhi kunciphisa ukusebenza kwegumbi.
Imisebenzi Yophucoko Nokulungisa
Ukuphucuka kweziphumo zomshini wokwenta umshini kunciphisa ukulunga kwegumbi kanye nokusebenza okuhle kwegumbi yokubamba. Ukulungisa okuthuthukile kwezigaba zokulunga, ukuhlola izimpawu zokulunga, nokucima kwegumbi yokuhlaza kuzindlela ezingcono kunezinyathelo ezibalulekile ekuphucosheni.
Ukudala isikhwama esigcwele sokuphucuka okufaka izahloli ngemini nesikhathi esijulile sokucimela kunciphisa izinkinga ngaphambi kokuba sithinte ubunzima bokwakha. Lokhu kususa kakhulu kwebunzima kunciphisa isikhathi esingekho kusebenzi kanye nokugcina ubude bezinsuku zomshini ngendlela ethembekile yokuphatha izimpahla.
Imibuzo Evame Ukubuzwa
Ukusabela kwesikhwama kuthinta kanjani izidingo zokulunga komshini?
Isivinimini samandla sibophepha ngokudla kusivinimini sesikhathi esithile sokubekwa kwifilimu yokushukuma, kudinga ukulungiswa okuhle ngezimali zemali. Izivinimini ezinkimbinkimbi zidinga izimali ezide ukufakwa kusivinimini esincane, ngelixa izivinimini eziphazanyayo zingadinga izimali ezincane ukuze kugweshwe ukunqamuka kakhulu. Ukuthola isilinganiso esihle phakathi kwezivinimini nezimali kuyisidingo ekugcineni ubumnandi nokusebenza.
Yintoni eyenza ukunciphisa okungafaniyo kumsebenzi wokupakisha?
Ukushukumana okungahle kusuke kube yindlela eyodwa, kufana nokungahle kwebiza emkhawulweni waphakathi kwegumbi, ukukhetha kwezilinganiso ezimbi zefilimu, noma amandla aphathelene ngendlela engahle. Ezinye izizathu ezikwenzela ngabe kungaba nguqukumba noma ifilthi yesiseko sangenhla, izimali ezingahle, noma izinto zezinhloso ezingavumele umsebenzi wokushukumana.
Kungani kufanele kubuzwe izimali zegumbi lokunqamuka?
Kufanele kubekekekile ukusetha kwezinklinga zomthwalo wokushisa ekupheleni kwesikhathi esinye ngasinye sokulima nokuguquka okukhulu kohlelo lwempilo noma ubude bezilonda. Kungafanele kubekekekile uma izimo zangaphakathi ziguqulwa kakhulu noma xa kusuke kuthuthela imiba yokulinganiswa. Ukuqinisekisa okudala kakhulu kusiza ukuhlanjelana nokulinganiswa kwegciwini futhi kumemeza imiba yezimali.
