Ulwazi oluyisisekelo lwe-silicone sealant (1) ---- Ukuhlukaniswa kwe-silicone sealant

I-SILICONE, engumkhiqizo oyingxenye ye-organic silicon. Ihlukaniswe kakhulu ngohlobo lwe-deacetic acid, uhlobo lwe-dealcoholization, uhlobo lwe-deamination kanye nohlobo lwe-deoxime. Ukwakhiwa kwamakhemikhali yi-polydimethylsiloxane, kanti i-polymer ye-silica ingabizwa ngokuthi i-silicone. I-Silicone sealant iyisigcobo-efana nento eqina ibe irabha eqinile,-efana nokuqinile yake yachayeka kumswakama emoyeni.

1. Ukuhlukaniswa kwe-silicone sealant

Eyodwa-ingxenye kanye nezimbili-ingxenye.

I-One-component silicone sealant yelashwa ngokuthintana nomswakamo osemoyeni kanye noshintsho lwezakhiwo zomzimba;

I-Two-component isho ukuthi i-silicone sealant ihlukaniswe yaba amaqembu amabili, A no-B. Alikho iqembu elingelapheka uma likhona lodwa, kodwa amaqembu amabili eglue azoqina uma esexubile.

Okuvame ukubonakala emakethe i-single-ingxenye ye-silicone sealant. I-Single-component silicone sealant ihlukaniswe yaba i-asidi futhi ingathathi hlangothi ngokuya ngezici zayo. I-Acid silicone sealant isetshenziselwa ikakhulukazi ukuhlanganisa okuvamile phakathi kwengilazi nezinye izinto zokwakha. I-Silicone sealant engathathi hlangothi inqoba izici ze-acid silicone sealant egqwalisa izinto zensimbi futhi isabela ngezinto ezine-alkaline, ngakho inohlu olubanzi lwezinhlelo zokusebenza futhi intengo yayo yemakethe iphakeme kancane kune-acid silicone sealant. Uhlobo olukhethekile lwe-silicone sealant emakethe i-silicone structural sealant. Ngenxa yokuthi isetshenziselwa ngokuqondile ukwakheka kwensimbi nengilazi noma ukuhlanganiswa okungeyona-isakhiwo sokuhlanganisa izindonga zamakhethini engilazi, izidingo zekhwalithi kanye nebanga lomkhiqizo ziphakeme kakhulu phakathi kwamaglue engilazi. Intengo yemakethe nayo iphakeme kakhulu.

1. 1. Isetshenziselwa ikakhulukazi izinto zokuhlanganisa ezakhiwe noma ezingezona-ezesakhiwo phakathi kwensimbi nengilazi yezindonga zamakhethini engilazi.
2. 2. Ingakwazi ukuxhuma ngokuqondile ingilazi ebusweni bezingxenye zensimbi ukuze kwakhiwe ingxenye yomhlangano owodwa, ehlangabezana nezidingo zokuklama izindonga zamakhethini ezinamafreyimu aphelele noma ama-semi-afihliwe.
3. 3. Ukuhlanganiswa kwesakhiwo nokuvalwa kwengilazi yokuvikela.
