I-Silicone sealant njengalapho manje isisetshenziswa kabanzi kuzo zonke izinhlobo zezakhiwo. Udonga lwamakhethini kanye nezinto zokuhlobisa zangaphakathi nezangaphandle zamukelwe yiwo wonke umuntu.
Kodwa-ke, ngokuthuthukiswa okusheshayo kokusetshenziswa kwe-silicone sealant ezakhiweni, izinkinga ezithinta ukusebenza nokuphepha kwezakhiwo ezihambisanayo zivela kancane kancane.
Ngakho-ke, kuyadingeka ukuqinisa ukuqonda kokusebenza komkhiqizo we-silicone sealant.
I-Silicone sealant isekelwe ku-polydimethylsiloxane njengento eluhlaza eyinhloko, ehambisana ne-ejenti ehlanganisayo, i-filler, i-plasticizer, i-coupling agent, i-catalyst ku-vacuum exutshwe unamathisele, ekamelweni lokushisa ngokusebenzisa amanzi emoyeni kufanele iqiniswe ukuze yenze irabha ye-silicone enwebekayo.
I-Silicone sealant iwuhlobo lwengilazi nezinye izinto eziyisisekelo zokubopha nokuvala izinto. Kunezigaba ezimbili eziyinhloko: i-silicone sealant ne-polyurethane sealant (PU).
I-Silicone sealant inezinhlobo ezimbili ze-acetic ne-neutral (i-sealant engathathi hlangothi ihlukaniswe yaba: i-stone sealant, i-anti-fungus sealant, i-fire sealant, i-pipeline sealant, njll.); Njenge-OLV 168 ne-OLV 128, banokusetshenziswa okuhlukile.
I-OLV168 acetic acetic silicone sealant fast vulcanization ekamelweni lokushisa, i-thixotropic, akukho ukugeleza, ukumelana nokuguga okuhle, ukumelana nowoyela, ukumelana namanzi, ukumelana ne-asidi ehlanjululwe, ukumelana ne-alkali, ukumelana nokushisa okuphezulu nokuphansi, kungasetshenziswa ku-60 ℃ ~ 250℃, inokubekwa uphawu okuhle, ukumelana nokushaqeka kanye nokumelana nomthelela.
I-acetic isetshenziselwa ikakhulukazi ukuhlanganisa okuvamile phakathi kwengilazi nezinye izinto zokwakha. I-Neutral inqoba izici zensimbi yokugqwala kwe-asidi nokusabela ngezinto ze-alkali, ngakho inobubanzi obubanzi bokusebenza, futhi intengo yayo yemakethe iphakeme kancane kune-asidi. Uhlobo olukhethekile lokungathathi hlangothi emakethe i-silicone sealant yesakhiwo, ngoba isetshenziswa ngokuqondile odongeni lwamakhethini ensimbi kanye nesakhiwo sengilazi noma umhlangano wokuhlanganisa okungekho kwesakhiwo, ngakho-ke izidingo zekhwalithi kanye nebanga lomkhiqizo liphezulu kakhulu ku-glue yengilazi, imakethe yayo. intengo nayo iphakeme kakhulu.
