Girazi Kucheka Girazi Kuchenesa uye PVB Firimu Kucheka
● Cheka girazi zvakanaka nekukura chaiko
● Tarisa pamusoro pegirazi uye bvisa mafuta nemarara, chenesa girazi nemvura yepombi.
● Sukurudza girazi nemvura yakasvinwa / mvura yakanyoroveswa. Hunhu hwemvura ＜ 30μS, kuoma kwemvura ＜ 10 PPM, tembiricha iri 40- 60 ℃.
● Mhepo omesa girazi uye chengeta iri kure nekusvibiswa.
● PVB firimu inofanirwa kutemwa pakureba kwakakura kupfuura 2 ～ 5mm kuwedzerwa kupfuura saizi yegirazi.
Kuomesa
● Imba yekunamatira --- Iyo tembiricha mukamuri ye lamination inofanirwa kunge iri 20 ～ 25 ℃, hunyoro hunofanirwa kunge huri 23% ± 2%, humbowo hwehutu, chengetedza michina yakashambidzika, vashandi vanofanirwa kuchengeta yunifomu yakachena, ngowani uye grove rekudzivirira PVB firimu kubva kumarara, zvinosvibisa uye bvudzi.
● Lamination mamiriro:
a) Iyo tembiricha yepamusoro tembiricha-- 20 ～ 30 ℃, iyo yepamusoro haifanirwe kupfuura 40 ℃.
b) Iyo PVB firimu tembiricha-- 20 ～ 25 ℃.
c) Tarisa zvakare iyo PVB firimu uye girazi rakarongedzwa uye saizi yegirazi inonyatsoenderana neiyo PVB firimu saizi.
Pre-Kumanikidza Kuneta
Kutonhorera kutonhora uye kupisa kupisa
a) Cold vharuvhu - Kukanganiswa kwevhavha dhigirii inofanirwa kunge iri pa580 ～ 680mmHg, tembiricha pa20 ～ 25 ℃, kumanikidza pa -0.095 ～ -0.1MPa. Zvinotora maminetsi makumi maviri muKuenderera Mbichana Kupomba, nepo maminetsi makumi matatu muUsi-uchienderera Kupora Kupomba.
b) inopisa inopisa - Iyo yegirazi yepamusoro tembiricha inofanira kunge iri pa100 ～ 120 ℃, zvinotora maminetsi makumi matatu nemashanu, makumi mashanu, kumanikidzwa kunofanira kuve -0.095 ～ -0.1MPa. Girazi rinogona kutorwa kunze kana tembiricha yodzikira kusvika 60-80 ℃.
● Kupeta Kuneta:
a) Chekutanga thermostat - → Iyo inopisa Laminated Girazi yepamusoro tembiricha iri 30 ～ 40 ℃ - → Yekutanga roller, kumanikidza kuri 5 ～ 8Mpa, iyo roller nzvimbo inofanirwa kuve 1-2mm isingasviki Laminated girazi ukobvu - → Yechipiri thermostat - → iyo yakavezwa girazi tembiricha yepamusoro ndeye 65 ～ 80 ℃, kumanikidza kuri 5 ～ 8Mpa, iyo roller nzvimbo iri 2-3mm yakaderera pane yakaomeswa girazi ukobvu.
b) Chengetedza iyo tembiricha tembiricha nebasa rinoenderera
Yakakwira Pressure Fform
Iyo tembiricha uye kumanikidza kukwira kuri pazasi kumhanya panguva yese maitiro. Maitiro ari pazasi ekutarisa:
Simudza tembiricha uye kumanikidza- → Tembiricha yakwira kusvika ku60 ℃, Kumanikidza kusvika ku0.4MPa- → Kumanikidza kusvika ku0.8MPa, kupisa kusvika ku90 ℃ - → Kumanikidza kusvika 1.0MPa ,, Kupisa kusvika ku135-140 ℃ - → Simudza tembiricha kusvika ku1.05 ～ 1.28 MPa - → Chengetedza iyo tembiricha 30- 60 maminetsi (zvinoenderana negirazi ukobvu uye huwandu) - → Chengetedza kumanikidza, zvakasununguka kudzikisa tembiricha kusvika 90 ℃ - → Kupisa kunodzikira kusvika ku45 ～ 55 ℃, kusunungura mweya
