Girazi rakakanyiwa, rinoumbwa nezvidimbu zviviri kana kupfuura zvegirazi ne organic polymer intermediate film, nekuda kwekushanda zvakanaka kwekuchengetedza, dziviriro yakasimba, kudzivirira ruzha uye mabhenefiti ekuderedza ruzha, girazi rakakanyiwa rave richishandiswa zvakanyanya mumunda wekuvaka. Zvichienderana nefirimu repakati, rinogona kukamurwa kuita girazi rakakanyiwa rePVB intermediate film, girazi rakakanyiwa reSGP intermediate film, girazi rakakanyiwa reEVA intermediate film, girazi rakakanyiwa repakati pefirimu nezvimwewo.
Hupenyu hwegirazi rakaiswa laminated hunonyanya kuenderana nezvinhu zviri mufirimu repakati. Nekuti TPU ine hunhu hwakanaka hwemakanika, kuramba kweultraviolet, kuramba kwehydrolysis, kujeka kwakanyanya uye hunhu hwakawanda hwakanaka, indasitiri yegirazi yave ichinetseka zvikuru, mabhenefiti eTPU mumunda wekushandiswa kwegirazi rekuvaka anowedzera zvishoma nezvishoma, TPU firimu repakati rakaiswa laminated girazi zvishoma nezvishoma.
Kushandiswa kwefirimu reTPU mumunda wegirazi rekuvaka
Kana tichienzanisa negirazi rechinyakare, girazi rakaiswa laminated rine mabasa ekuchengetedza, kudzivirira ruzha uye kudzivirira mwaranzi. Zvidimbu zvegirazi rakaiswa laminated zvinonamirwa pafirimu kunyangwe girazi rakatyoka, zvichidzivirira kuitika kwekukuvara kwemavanga uye kupinda kwezviitiko zvekudonha. Kazhinji, girazi rakaiswa laminated reEVA rinonyanya kushandiswa pakuparadzanisa mukati meimba, girazi rakaiswa laminated rePVB, girazi rakaiswa laminated reSGP rinogona kushandiswa kuvaka magonhi ealuminium akapwanyika uye mahwindo kana madziro ejira.
Firimu reTPU sefirimu repakati rinogona kusungirirwa kubhodhi regirazi nePC, bhodhi regirazi neacrylic, girazi negirazi, nezvimwewo. Kana tichienzanisa nefirimu repakati rePVB, firimu repakati reSGP, firimu reTPU rine hunhu hunotevera:
1. Simba rakakwirira
Firimu reTPU rine simba rakawanda, mutoro wakakwira uye kuramba kumanikidzwa nemhepo pasi pechimiro chegirazi uye ukobvu hwakafanana.
2. Kuchengetedzwa kuri nani mushure mekupwanya
Firimu reTPU rine simba guru rekudhonza uye simba rekubvarura, uye girazi rakaiswa laminated rine rutsigiro rwakasimba mushure mekupwanyika.
3. Kushanda kwemaziso kuri nani
Firimu reTPU rine chiedza chakawanda uye mhute yakaderera, uye rine kupenya kwakanyanya uye simba rekuona mushure mekusanganisa negirazi.
Nekuti firimu repakati reTPU rine hunyanzvi hwepamusoro hwekubatanidza, hunyanzvi hwekuona uye hunyanzvi hwemakanika, rinoshandiswa zvakanyanya muminda yemauto neyevanhuwo zvavo, uye girazi rinodzivirira mabara rakagadzirwa nefirimu iyi rinogona kushandiswa mundege, mota dzemhando yepamusoro dzinodzivirira mabara uye mabhangi.
Girazi rakanamirwa reTPU rine zvinhu zvakawanda zvekuchengetedza uye zvakanakira zviri pachena kana tichienzanisa negirazi remazuva ano, uye zvinodiwa zvemagadzirirwo emazuva ano egirazi zvinopa nzvimbo yakakura yekuvandudza girazi rakanamirwa reTPU. Panguva imwe chete, zvichikanganiswa nemutemo uyu, mafambiro ese ezvigadzirwa zvekuvaka zveChina ndekuchengetedza simba nekuchengetedza nharaunda, uye TPU sechinhu chisina njodzi kunharaunda inoenderana nemutemo wekuvandudza weChina uripo iye zvino.
Firimu reTPU: firimu repakati rine hunyanzvi hwekubatanidza
Firimu reTPU (thermoplastic polyurethane) chinhu chinoshandiswa zvakasiyana-siyana chinozivikanwa sefirimu repakati rekubatanidza zvinhu zvakasiyana-siyana. Hunhu hwaro hwakasiyana hunoita kuti rive sarudzo yakanaka yekushandisa munzvimbo dzine zvinhu zvechinyakare zvakaita sePVB neSGP.
Chimwe chezvakanakira zvikuru zveTPU film kugona kwayo kubatana nezvinhu zvakasiyana-siyana, zvinosanganisira girazi, maPC board, ma acrylic sheets, uye kunyange mamwe magirazi. Izvi zvinoita kuti ive sarudzo inoshandisika zvakanyanya mumaindasitiri akadai semotokari, kuvaka uye zvemagetsi.
TPU ine zvakanakira zvakawanda kupfuura mafirimu echinyakare anobatanidza zvinhu. Chekutanga, firimu reTPU rinonamira zvakanaka kune zvikamu zvakasiyana, zvichiita kuti rive nechisungo chakasimba uye chinogara kwenguva refu. Izvi zvinonyanya kukosha mukushandiswa kwezvinhu zvakabatana kana kuti zvinhu zvakasungirirwa zvichikanganiswa nemagetsi kana zvakatipoteredza.
Pamusoro pezvo, mafirimu eTPU anopa kujeka kwakanaka kwemaziso, zvichiita kuti ave akakodzera kushandiswa kunoda kujeka kwakanyanya. Izvi zvinobatsira zvikuru muindasitiri yemotokari, uko mafirimu eTPU anogona kushandiswa kunamira girazi kuti riwedzere kuchengetedzeka uye kuona zvakanaka.
Pamusoro pezvo, mafirimu eTPU anodzivirira zvakanyanya kutsvuka uye kuora, zvichiita kuti ishande kwenguva refu uye runako rwayo. Kugona kwayo kuchengetedza kushanda kwayo pamusoro pekupisa kwakakura kunoitawo kuti ive yakakodzera mamiriro akasiyana ekunze.
Pamusoro pezvo, mafirimu eTPU anozivikanwa nekuchinjika kwawo uye kuramba kukanganiswa, izvo zvinowedzera kukodzera kwawo kushandiswa kwenamira. Kugona kwayo kuenderana nenzvimbo dzakakombama uye kutsungirira mitoro inochinja-chinja kunoita kuti ive sarudzo yakavimbika yekushandiswa kunoda simba.
Muchidimbu, firimu reTPU rave firimu repakati rinoshandisika pakusunga kune akasiyana-siyana ma substrates. Musanganiswa waro wakasiyana wehunhu, kusanganisira kunamira, kujeka kwemaziso, kugara kwenguva refu uye kuchinjika, zvinoita kuti ive sarudzo yekutanga kune mashandisirwo uko ma interlayers echinyakare angasaita basa rinodiwa. Sezvo maindasitiri achiramba achitsvaga mhinduro itsva dzematambudziko ekubatanidza, mafirimu eTPU angangoita basa rakakosha mumhando dzakasiyana dzemashandisirwo.
