Amaphaneli Egumbi Elibandayo le-PU Athuthukisa Ukusebenza Kokugcina Okubandayo

Indawo yokugcina izinto ebandayo idinga ukunemba nokusebenza kahle, amaphaneli egumbi elibandayo le-PU asebenza njengendinganiso yemboni yokushisa. Amaphaneli esandwich e-PU adala isithiyo, asiza amakamelo abandayo agcine izinga lokushisa elizinzile futhi anciphise ukulahleka kwamandla. Abakhi abaningi bakhetha amaphaneli e-PU ngoba bafuna ukushisa okuqinile, ukufakwa okusheshayo, kanye nokuphila isikhathi eside kwenkonzo. Agcina amazinga okushisa angaphakathi azinzile ukuze kuphephe ukudla. Amabhizinisi athembele kuwo ekuthuthweni nasekugcinweni kwempahla.

Izinzuzo Zokusebenzisa Amaphaneli Egumbi Elibandayo le-PU

Amaphaneli egumbi elibandayo le-PU anikeza ukuvikela okuqinile ngoba ingaphakathi libonisa ukudlulisa ukushisa okuphansi kakhulu. Ingaphakathi elijwayelekile le-PU lifinyelela ubuningi obuphakathi kuka-38 no-42 kg nge-cubic meter ngayinye. Lokhu kuqina kusekela amanani okudlulisa ukushisa angu-0.018 kuya ku-0.024 W nge-Kelvin ngemitha. Iphaneli yegumbi elibandayo le-PU engu-100-mm igcina ukudluliselwa kokushisa kungaphansi kuka-0.25 W ngemitha yesikwele i-Kelvin. Amakamelo aqandisayo avame ukusebenza kuma-degrees angu-18 noma ngaphansi, kanti amaphaneli egumbi elibandayo le-PU agcina izinga lokushisa elizinzile kulezi zimo. Abasebenzisi abaningi babika ukonga kwamandla ngamaphesenti ayi-10 kuya kwangu-18 uma bethuthuka kusuka ku-foam ephansi kuya ezinhlelweni ze-PU ezixinene kakhulu. Ama-PU cores nawo agcina ukumuncwa komswakama kungaphansi kwamaphesenti amabili ngevolumu, okuvikela inani lokuvikela isikhathi eside.

Amaphaneli e-PU akhonza izinhlobo eziningi zamakamelo abandayo, okuhlanganisa amakamelo aqandisayo, amakamelo okupholisa, indawo yokugcina izithelo, izindawo zokucubungula inyama, kanye nezindawo zokugcina imbewu. Iphaneli ye-PU engu-75-mm ifanela amakamelo anezinga lokushisa eliphakathi kwama-degrees angu-0 no-10. Iphaneli engu-100 mm ifanela ama-degrees angaphansi kuka-10 kuya ku-18. Iphaneli engu-150 mm ifanela ama-degrees angaphansi kuka-20. Futhi engu-200 mm ifanela ama-degrees angaphansi kuka-25 noma ngaphansi.

Amaphaneli esandwich e-PU asebenzisa izikhumba zensimbi ezisukela ku-0.4 kuya ku-0.6 mm ubukhulu. Lezi zikhumba zihlangabezana namandla okukhiqiza angu-235 kuya ku-280 MPa. Ubuso bensimbi eqinile buvikela umongo we-foam futhi busekela imithwalo yangaphakathi yemishini. Iphaneli ye-PU ejwayelekile engu-100 mm ifinyelela amandla okucindezela angu-150 kuya ku-180 kPa. La mandla aqinisekisa ukuhambisana okuzinzile kuamakamelo abandayongezimoto eziningi ezihamba ngezinyawo. Abaningiindawo yokugcina ebandayoAbakhi basebenzisa amajoyinti olimi nomsele ngoba athuthukisa ukungabi nomoya. Ijoyinti elivalwe kahle linciphisa ukuvuza kwamandla ngamaphesenti ayi-10 kuya kwangu-15. Amaphaneli abonisa futhi amanani okunciphisa umsindo aseduze nama-decibel angu-25 kuya kwangu-28, okusiza ukulawula umsindo ngaphakathi kwezindawo zokucubungula.

Ikhwalithi Yokuqukethwe Ephakeme

Izinto zokusetshenziswa zinquma ubude bomkhiqizo wokugcina. Njengoba iphaneli yesangweji inamaphaneli amaningi ensimbi, ukwelashwa kokulwa nokugqwala ebusweni bomkhiqizo kubaluleke kakhulu. Ukwembozwa kwe-zinc okungu-120g/m² kuya ku-275g/m² kuvikela insimbi. Lokhu kuvimbela ukugqwala ezindaweni ezibandayo ezimanzi. Ukwembozwa okuphezulu njenge-PVDF noma i-HDP kumelana nokugqwala kwamakhemikhali. Ubukhulu bepende buvame ukuba ngama-microns angu-25. Lolu ngqimba oluvikelayo luqinisekisa ukuthi umbala awupheli.

I-Harbin Dong`an Building Sheets Company ingumkhiqizi ohamba phambili wamaphaneli esandwich eShayina. Le nkampani inomlando omningi eminyakeni engaphezu kwengu-40. Inkampani i-Dong`an ibheka ukubaluleka okukhulu kwikhwalithi yemikhiqizo yayo. I-Dong`an ithola insimbi kubaphakeli bekhwalithi ephezulu. Bavame ukusebenzisa izinto ezivela kumikhiqizo edumile neyezinga eliphezulu. Ubukhulu beshidi lensimbi busukela ku-0.4 mm kuya ku-0.8 mm ukuqinisekisa amandla esakhiwo semikhiqizo yamaphaneli esandwich. I-Dong`an ihlola yonke inqwaba yezinto zokusetshenziswa ngokucophelela. Izinto ezihlangabezana nezindinganiso zomhlaba wonke kuphela ezingena emgqeni wokukhiqiza.

Ubuchwepheshe Bokukhiqiza eHarbin Dong`an

I-Harbin Dong`an isebenzisa imigqa yokukhiqiza yesimanje. Umugqa wabo wokukhiqiza oqhubekayo udala ikhwalithi efanayo. Izinhlelo zekhompyutha zilawula inqubo yokugqwala ngokunembile. Lokhu kuqinisekisa ubuningi obufanayo kulo lonke iphaneli. Basebenzisa imishini yokugqwala enomfutho ophezulu. Umfutho womjovo ufinyelela ku-150 bar. Lokhu kuqinisekisa ukuthi igqwala ligcwalisa yonke ikona kahle. Amandla okubopha phakathi kwensimbi negqwala ayamangalisa. Idlula i-0.09 MPa ezivivinyweni ezijwayelekile. Isikhathi sokukhuphuka kwegqwala sihlala ngaphakathi kwemizuzwana eyisishiyagalombili kuya kweyishumi, okusekela ukwakheka kwamaseli okufanayo. I-laminator isebenzisa umfutho olinganiselayo we-0.1 kuya ku-0.2 MPa ngesikhathi sesigaba sokupholisa.

Lokhu kucindezela okufanayo kuqeda ukugoba kwamaphaneli kanye nokungahambi kahle kobuso. Ubuchwepheshe bokusika obuthuthukisiwe buqinisekisa ukunemba kobukhulu. Amaphaneli afika endaweni elungele ukuhlanganiswa. Ukubekezelelana kuhlala kungaphakathi kwamamilimitha ama-2. Ifektri isebenzisa imishini yokufaka ngokuzenzakalelayo enciphisa umonakalo wemishini futhi igcina ukuguquguquka komphetho kungaphansi kwe-1 mm. Lokhu kunemba kususa izikhala ngesikhathi sokufakwa. Izindawo zensimbi ezibushelelezi zivumela ukuhlanza okulula futhi zisekele ukuhambisana ne-HACCP kanye ne-GMP. Lezi zici zenza amaphaneli e-PU afaneleke kakhulu ekucutshungulweni kokudla, kwemithi, kanye nezinhlelo zokusebenza ze-logistics.

I-Harbin Dong`an inikeza izinhlelo zokwengeza ezifana nezingcezu zamakhona, ama-aluminium rails, ama-sealant, kanye nama-stainless fasteners. Lezi zingxenye zandisa impilo yesistimu futhi zivimbele ukugqwala ezindaweni ezinomswakama. Amafilimu avikelayo anobukhulu obungama-micron angu-60 kuya kwangu-80 anciphisa amazinga okulimala kwezokuthutha abe ngaphansi kwephesenti elilodwa. Abathengi bathola ukuzethemba ngoba isigaba ngasinye silandela izinqubo ezijwayelekile ngaphansi kokuphathwa kwekhwalithi ye-ISO 9001.

Isevisi kanye nokwenza ngokwezifiso

I-Harbin Dong`an ibeka phambili ukwaneliseka kwamakhasimende kanye nokusekelwa. Ithimba labo lobunjiniyela lisiza ngokuklama amakamelo abandayo. Bala ubukhulu bephaneli obudingekayo ngokusekelwe endaweni. I-Dong`an inikeza izixazululo ezenzelwe wena kuzo zonke izidingo. Umthamo wabo wokukhiqiza udlula amamitha-skwele angu-2,000 nsuku zonke. Lokhu kuqinisekisa ukulethwa okusheshayo kwamaphrojekthi amakhulu. Banikeza isikhathi sewaranti esifinyelela eminyakeni eyi-15. Lokhu kuzibophezela kufakazela ukuzethemba kwabo ngekhwalithi yomkhiqizo. Usekelo lobuchwepheshe luhlala lutholakala kuyo yonke inqubo yokufaka. Amaklayenti athola isiqondiso mayelana nokugcinwa nokunakekelwa.
