Amaphaneli okugcina izinto ezibandayo asebenza njengezingxenye eziyinhloko ze-logistics ye-cold chain futhi athonya ngqo ikhwalithi yokugcina ukudla nemithi. Izimpahla ezibolayo zidinga ukulawulwa kokushisa okuzinzile kulo lonke isitoreji kanye nokuthuthwa. Iphaneli yokugcina izinto ezibandayo efanelekile kumele imelane nokubanda okukhulu ku-−30 °C ngaphandle kokulahlekelwa ukusebenza kahle. Iphaneli kumele futhi igcine ukuqina ezindaweni ezinomswakama isikhathi eside senkonzo.
Ukuqonda inqubo yokukhiqiza kusiza abathengi ukuthi bakhethe imikhiqizo efanelekile kanye nabaphakeli abathembekile. Lolu lwazi luphinde lunciphise izingozi zephrojekthi kanye nezindleko zokusebenza zesikhathi eside. Abakhiqizi bakhiqiza amaphaneli okugcina izinto ezibandayo ngezinyathelo eziningana ezibalulekile.
Lezi zinyathelo zifaka phakathi ukwakheka kwamaphaneli ensimbi, ukufafaza okunamathelayo, kanye nokufakwa kwezinto ze-foam. Inqubo iyaqhubeka nokufakwa kwe-foam yezinto eziyinhloko, ukusika amaphaneli, ukwelapha, kanye nokuhlolwa kokugcina. Isinyathelo ngasinye sithinta amandla amaphaneli, ukusebenza kahle kokushisa, kanye nokuphila kwesevisi. Abakhiqizi kumele balawule zonke izigaba ukuqinisekisa ikhwalithi yomkhiqizo ehambisanayo.
Ukukhethwa Kwezinto Zokugcina Izinto Ezibandayo
Ikhwalithi yephaneli yensimbi ifanelwe ukunakwa okuyinhloko. Amaphaneli ensimbi asebenza njengohlaka lwesakhiwo samaphaneli okugcina abandayo. Anquma ngqo amandla aphelele kanye nokuqina kobukhulu. Ukukhetha okujwayelekile kusebenzisa amaphaneli ensimbi anombala wekhwalithi ephezulu anobukhulu obungu-0.5 mm. Abakhiqizi bamboza la maphaneli nge-resin ye-polyester ukuze bamelane nokugqwala. Isembozo sivikela namaphaneli ekulimaleni kokushayisana ngesikhathi sokuthutha nokufakwa.
Abanye abahlinzeki abancane behlisa amanani ngokunciphisa izindleko zezinto zokwakha. Bavame ukusebenzisa amaphaneli ensimbi anobukhulu obungu-0.3 mm. Amaphaneli anjalo aguquguquka kalula ngaphansi komthwalo noma izinguquko zokushisa. Ukuguqulwa kwandisa imvamisa yokulungisa kanye nezindleko zokulungisa. Amanani okuqala aphansi avame ukuholela ezindlekweni eziphakeme zesikhathi eside.
Abahlinzeki bekhwalithi basebenzisa izindinganiso zezinto eziqinile. Njengoba nje iHarbin Dongan Building Sheets isebenzisa amaphaneli ensimbi aphakathi kuka-0.4 no-0.8 mm ubukhulu. Isisindo se-zinc coating sifinyelela okungenani ku-120 g/m² kuzo zombili izinhlangothi. Lokhu kuchazwa kuvimbela ukugqwala iminyaka engaphezu kweyishumi. Amaphaneli amakhulu athuthukisa nokumelana nokushayisana kanye nokuqina kwesakhiwo. Lezi zinzuzo zisekela imisebenzi yokugcina amakhaza isikhathi eside.
Ikhwalithi yezinto eziyinhloko idlala indima ebaluleke ngokulinganayo. Ingqikithi inquma ukusebenza kokushisa kanye nokusebenza kahle kwamandla. I-polyurethane foam enomfutho ophezulu ibusa imakethe yesimanje yokugcina izinto ezibandayo. Ukushisa kwayo kuhlala ku-0.024 W/(m·K) noma ngaphansi. Ukushisa okuphansi kunciphisa ukudluliselwa kokushisa kanye nokulahlekelwa amandla.
Abakhiqizi bekhwalithi balawula ngokucophelela ubuningi be-foam. I-Dongan igcina ubuningi be-polyurethane obuphakathi kuka-38 no-42 kg/m³. Lolu hlu lulinganisela ukusebenza kahle kokuvikela kanye namandla omshini. Ubuningi obuphansi buthaka isakhiwo, kuyilapho ubuningi obuphezulu bunciphisa ukusebenza kahle kokuvikela. Ukulawulwa kobukhulu okufanele kuqinisekisa ukusebenza okuzinzile ngaphansi komthwalo.
Izinto ezikhipha amagwebu nazo zithinta ikhwalithi yokuvikela. Abakhiqizi kufanele bakhethe izinto ezisezingeni eliphezulu ezifana ne-HCFC-141B. Izinto ezisezingeni eliphezulu zakha amaseli egwebu afanayo kanye namazinga aphezulu amaseli avaliwe. Amaseli afanayo athuthukisa ukumelana nokushisa kanye nokumelana nomswakama. Lokhu kukhetha kusekela ukuzinza kokuvikela isikhathi eside.
Inqubo Yokukhiqiza Amaphaneli Okugcina Izinto Ezibandayo
Imigqa yokukhiqiza ezenzakalelayo ivumela ukulawulwa kwenqubo okunembile. Ukukhiqiza kwanamuhla kudinga izilinganiso zezinto ezinembile kakhulu. Imigqa eqhubekayo ezenzakalelayo ihlangabezana nalezi zidingo ngempumelelo. Imakethe ithanda kakhulu ukukhiqizwa kwamaphaneli okugcina abandayo okuzenzakalelayo.
Izinhlelo zekhompyutha zilawula izinga lokushisa le-foam, ingcindezi, kanye nesikhathi sokuphendula. Lezi zinhlelo zigcina izimo ezizinzile kulo lonke ukukhiqizwa. I-foam yezinto zokusetshenziswa ihlale isezingeni cishe ku-38 °C. Izinga lokushisa elizinzile lithuthukisa isakhiwo se-foam kanye nokusebenza kokubopha. Izinga lamaseli avaliwe lifinyelela okungenani amaphesenti angama-95 ngemva kokukhipha i-foam.
Ukugqwala okuzenzakalelayo kunikeza izinzuzo ezicacile kunezinqubo ezenziwa ngesandla. Ukugqwala okuvamile okwenziwa ngesandla kudala ubuningi obungalingani kanye nezindawo ezibuthakathaka. Ukugqwala okuzenzakalelayo kukhiqiza ama-core afanayo kuphaneli ngayinye. Ukwehluka kokuqhuba ukushisa kuhlala kungaphansi kuka-0.002 W/(m·K). Ukufakwa kokushisa okuqhubekayo kuthuthukisa ukusebenza kahle kwegumbi elibandayo.
Amaphaneli asezingeni eliphezulu anciphisa ukusetshenziswa kwamandla okusebenza ngemva kokufakwa. Abasebenzisi bavame ukonga amaphesenti angu-15 kuya kwangu-20 ezindlekweni zamandla. Isidingo samandla esiphansi sithuthukisa umnotho wephrojekthi kanye nokusimama. Ukuvikela okuzinzile kuvikela nezimpahla ezigciniwe ngempumelelo enkulu.
Ikhwalithi yokubopha iqinisekisa impilo ende yesevisi. Isakhiwo sephaneli sidinga ukunamathelana okuqinile phakathi kwezikhumba zensimbi nezinto eziyinhloko. Amandla okubopha athinta ngqo ukuqina nokuphepha. Ukwehluleka okuningi kokugcina amakhaza kwenzeka ngenxa yokuhlukaniswa kwamaphaneli. Izikhumba zensimbi ziyahlukana lapho amandla okubopha enganele.
Abakhiqizi kumele baqinisekise amandla okubopha anele. Amandla okubopha kufanele adlule ku-1.0 kg/cm². Iphaneli ngayinye yemitha yesikwele kufanele imelane namandla okudonsa ayithani elilodwa. Lezi zindinganiso zivimbela ukuhlukana ngaphansi kokucindezeleka kokushisa.
UDongan usebenzisa ingcina ye-polyurethane esezingeni eliphezulu enezingxenye ezimbili. Le ngcina inikeza ukusebenza okuqinile nokuhlala isikhathi eside kokubopha. Amaphaneli amasha ayaqina ku-70 °C amahora angama-24. Ukusika kuvumela ingcina ukuthi ifinyelele amandla afanele. Le nqubo ivimbela ukuhlukana phakathi nokushintsha okukhulu kwezinga lokushisa.
Ukuqapha Ikhwalithi Okuqinile
Ukuqapha ikhwalithi okuqinile kusekela ukusebenza komkhiqizo okuthembekile. Ukuhlolwa kokubukeka kumelela isinyathelo sokuqala sokulawula ikhwalithi. I-Dongan iqinisa amazinga okuhlola okubonakalayo aqinile. Izindawo zamaphaneli kumele zihlale zingenazo iziphambeko ezibonakalayo.
Ukungalingani kwendawo kumele kuhlale ngaphansi kuka-1.5 mm. Ukujula kokuklwebheka akumele kudlule u-0.2 mm. Ukuphambuka okuqondile kumele kuhlale ngaphansi kuka-2 mm. Lezi zindinganiso ziqinisekisa ukufakwa okunembile kanye namajoyinti ephaneli aqinile. Ukubukeka okuhle kubonisa nekhwalithi yokukhiqiza yangaphakathi.
Ukuhlolwa okuqinile kuqinisekisa ukusebenza okuzinzile kwesikhathi eside. Amakhasimende ayazuza ngokugcinwa okunciphile kanye nokuthembeka okuthuthukisiwe. Izindinganiso eziphakeme zivikela nedumela lomkhiqizo kanye nokwethenjwa kwamakhasimende.
Ukuhlolwa kokusebenza kwakha isigaba sokugcina sokulawula ikhwalithi. Iqoqo ngalinye lokukhiqiza lihlolwa ngokuphelele. Amaphaneli aqandisa ku-−30 °C amahora angama-24. Ochwepheshe base behambisa amaphaneli ngokushesha endaweni engama-60 °C. Abahloli baqaphela ukuqhekeka, ukuguquka, noma ukuhlukaniswa.
Lokhu kuhlolwa kokushaqeka kokushisa kulingisa izimo zokusebenza ezimbi kakhulu. Amaphaneli kumele agcine ubuqotho ngesikhathi sokushintsha kwezinga lokushisa okusheshayo. Ukuhlolwa okuphumelelayo kuqinisekisa ukukhethwa kwezinto kanye nokusebenza kahle kokulawula izinqubo. Amaphaneli afanelekayo kuphela afika emakethe.
Ngokukhetha izinto eziqinile, ukukhiqizwa okunembile, kanye nokuhlolwa okuqinile, abakhiqizi baqinisekisa amaphaneli okugcina izinto ezibandayo athembekile. Amaphaneli asezingeni eliphezulu avikela izimpahla, anciphisa ukusetshenziswa kwamandla, futhi asekela ukusebenza kweketanga elibandayo isikhathi eside.
