Girazi rakakanyiwa igirazi rinowanzoshandiswa mukugadzira girazi, iro rinozivikanwawo segirazi rerugare. Girazi rakakanyiwa rinoumbwa nezvikamu zvakasiyana-siyana zvegirazi, pamusoro pegirazi, chimwe chikamu chiri pakati pegirazi, kazhinji kune marudzi matatu esandwich: EVA, PVB, SGP.
Sangweji yePVB Trust ndeimwe yemazita anozivikanwa zvikuru. PVB imhando yesangweji inoshandiswawo mumagirazi ekuvaka uye magirazi emotokari pari zvino.
Maitiro ekuchengetedza uye nzira yekugadzirisa yePVB interlayer yakaoma kupfuura EVA, uye zvinodiwa zvekupisa nehunyoro zvakakwira. Kugadzirisa PVB kunoda kudzora tembiricha iri pakati pe18℃-23℃, kudzora hunyoro pa18-23%, PVB inonamatira ku0.4%-0.6% hunyoro, mushure mekupisa kwekutanga, kutenderera kana kuputira vacuum kunoshandiswa kwe autoclade kumisa kuchengetedza kupisa nekumanikidzwa, tembiricha ye autoclade: 120-130℃, kumanikidzwa: 1.0-1.3MPa, nguva: 30-60min. Midziyo yevatengi yePVB inoda mari inosvika miriyoni imwe, uye kune dambudziko rakati remabhizinesi madiki. Mumakore mashoma apfuura, kunyanya kune vekunze Dupont, Shou Nuo, mvura nevamwe vagadziri vanoshandisa, PVB yemumba inonyanya kudzokororwa data kuti imise kugadziriswa kwechipiri, asi kugadzikana kwemhando hakuna kunaka. Mumakore achangopfuura, vagadziri vevatengi vePVB yemumba vari kukurawo zvishoma nezvishoma.
PVB ine kuchengetedzeka kwakanaka, inochengetedza ruzha, yakajeka uye inodzivirira mwaranzi yemakemikari, asi inodzivirira mvura yePVB haina kunaka, uye iri nyore kuvhura munzvimbo ine hunyoro kwenguva yakareba.
EVA inomiririra ethylene-vinyl acetate copolymer. Nekuda kwekudzivirira kwayo mvura zvakanyanya uye kuramba kwayo ngura, inoshandiswa zvakanyanya mupakeji yemafirimu, shed film inoshanda, foam shoe material, hot melt adhesive, waya netambo nematoyi, nezvimwewo, China inowanzo shandisa EVA seruzivo rwega.
EVA inoshandiswawo sesandwich yegirazi rakaiswa laminated, uye mutengo wayo wakakwira. Kana ichienzaniswa nePVB neSGP, EVA ine basa riri nani uye tembiricha yakaderera yekubvisa tsvina, uye inogona kugadziriswa kana tembiricha yasvika pa110℃. Midziyo yayo yese yevatengi inoda anenge 100,000 yuan.
Firimu reEVA rine basa rakanaka, rinogona kumisa kusungirirwa kwewaya uye kutenderedzwa muchikamu chefirimu kuti rigadzire girazi rakanaka rekushongedza rine mapatani nemapatani. EVA ine simba rakanaka rekudzivirira mvura, asi haipindi mumwaranzi yemakemikari, uye kugara zuva kwenguva refu kuri nyore kuita yero nedema, saka inonyanya kushandiswa pakuparadzanisa mukati meimba.
SGP inomiririra ionic intermediate membrane (Sentryglass Plus), inova sandwich yakagadzirwa neDuPont. Kushanda kwayo kwepamusoro kunoratidzwa mu:
1, hunhu hwakanaka hwemakanika, simba rayo guru. Pasi peukobvu hwakafanana, kugona kweSGP sandwich kwakapetwa kaviri kupfuura PVB. Pasi pemutoro neukobvu hwakafanana, kutsauka kwegirazi rakanamirwa reSGP chikamu chimwe muzvina chePVB.
2. Simba rekubvarura. Pahukobvu hwakafanana, simba rekubvarura rePVB rinonamira firimu rinopetwa kashanu kupfuura rePVB, uye rinogonawo kunamirwa pagirazi pasi pemamiriro ekubvaruka, pasina kuita kuti girazi rese ridonhe.
3, kugadzikana kwakasimba, kuramba kwakanyorova. Firimu reSGP harina ruvara uye rinoonekera, mushure mezuva nemvura kwenguva refu, rinodzivirira mwaranzi yemakemikari, harisi nyore kuita yero, chiyero cheyero < 1.5, asi chiyero cheyero chefirimu rePVB sandwich i6~12. Saka, SGP ndiyo inodiwa negirazi rakachena kwazvo rakaiswa laminated.
Kunyangwe kushandiswa kweSGP kuri pedyo nekushandiswa kwePVB, mutengo wekupedzisira wakakwira, saka kushandiswa kwayo muChina hakuna kuwanda, uye kuzivikanwa kwayo kwakaderera.
