Laminated girazi igirazi rinowanzoshandiswa mumunda wegirazi rekuvaka, iro rinozivikanwawo segirazi rerunyararo. Laminated girazi inoumbwa neakawanda akaturikidzana egirazi, kuwedzera kune girazi, yasara ndiyo sandwich iri pakati pegirazi, kazhinji kune matatu marudzi esangweji: EVA, PVB, SGP.
.
PVB sandwich Trust nderimwe remazita anozivikanwa. PVB zvakare yakajairika sandwich zvinhu zvinoshandiswa mukugadzira girazi uye girazi remotokari parizvino.
.
Nzira yekuchengetedza uye nzira yekugadzirisa yePVB interlayer yakaoma kudarika EVA, uye zvinodiwa zvekushisa uye hunyoro zvakakwirira. PVB processing chikumbiro tembiricha kutonga pakati 18 ℃-23 ℃, hama humidity kudzora pa 18-23%, PVB kuomerera 0.4% -0.6% mwando kugutsikana, pashure preheating rolling kana vacuum muitiro ndiko kushandiswa autoclade kumisa kupisa kuchengetedza uye kumanikidzwa, autoclade tembiricha: 120-130 ℃, kumanikidza: 1.0-1.3MPa, nguva: 30-60min. PVB yevatengi midziyo inoda mari inosvika miriyoni imwe, uye pane kuomerwa nemabhizinesi madiki. Mumakore mashoma apfuura, kunyanya kune yekune dzimwe nyika Dupont, Shou Nuo, mvura uye vamwe vagadziri manwiwa, yepamba PVB inonyanya kudzokororwa data kumisa yechipiri kugadzirisa, asi kugadzikana kwemhando hakuna kunaka. Mumakore achangopfuura, vagadziri vevatengi vePVB vepamba vari kuwedzerawo zvishoma nezvishoma.
.
PVB ine chengetedzo yakanaka, kuvharisa inzwi, kujeka uye makemikari emwaranzi kuramba, asi PVB mvura kuramba haina kunaka, uye iri nyore kuvhura munzvimbo ine mwando kwenguva yakareba.
.
EVA inomirira ethylene-vinyl acetate copolymer. Nekuda kwekudzivirira kwayo kwakasimba kwemvura uye kushorwa kwekuora, inoshandiswa zvakanyanya mukurongedza firimu, inoshanda yakadururwa firimu, furo shangu zvinhu, inopisa inonyungudika inonamatira, waya uye tambo uye matoyi, nezvimwewo, China inowanzo shandisa EVA seruzivo rwega.
.
EVA inoshandiswawo sesangweji yegirazi yakashongedzwa, uye kuita kwayo mutengo kwakakwira. Kuenzaniswa nePVB neSGP, EVA ine chiitiko chirinani uye yakaderera ablation tembiricha, uye inogona kugadziriswa kana tembiricha yasvika 110 ℃. Yayo yakazara seti yemidziyo yevatengi inoda nezve 100,000 yuan.
.
Iyo firimu yeEVA ine basa rakanaka, iro rinogona kumisa nzira yekurovera kwewaya uye kukunguruka muchikamu chefirimu kugadzira yakanaka yekushongedza girazi ine mapatani uye mapatani. EVA ine mvura yakanaka inodzivirira, asi inoshingirira kumagetsi emwaranzi, uye kuratidzwa kwezuva kwenguva refu kuri nyore kune yero uye dema, saka inonyanya kushandiswa kugovera yemukati.
.
SGP inomirira ionic yepakati membrane (Sentryglass Plus), inova yakakwirira-inoshanda sandwich zvinhu zvakagadzirwa neDuPont. Kuita kwayo kwepamusoro kunoratidzwa mu:
.
1, yakanakisa michina zvivakwa, yakakwirira simba. Pasi pehukobvu hwakafanana, kutakura simba reSGP sandwich rakapetwa kaviri kune PVB. Pasi pemutoro wakafanana uye ukobvu, kubhenda kwegirazi reSGP laminated chikamu chimwe muzvina chePVB.
.
2. Kubvarura simba. Pakukobvu kwakafanana, simba rekubvarura rePVB rinonamira firimu rakapetwa kashanu iro rePVB, uye rinogonawo kunama kune girazi pasi pemamiriro ekubvarura, pasina kuita kuti girazi rose ridonhe.
.
3, kugadzikana kwakasimba, kushomeka kwemvura. Firimu reSGP harina ruvara uye rakajeka, mushure menguva refu yezuva uye mvura, inopesana nemwaranzi yemakemikari, isiri nyore kutsvuka, yero coefficient <1.5, asi iyo yero coefficient yePVB sandwich film ndeye 6 ~ 12. Naizvozvo, SGP ndiye mudiwa wegirazi rekupedzisira-chena laminated.
.
Kunyangwe iyo nzira yekushandisa yeSGP iri padyo neiyo yePVB, mutengo wekupedzisira wakakwira, saka iyo application muChina haina kunyanya kuwanda, uye kuziva kwayo kwakaderera.
