Isitywini seglasi
I-Glass sealant sisixhobo esisetyenziselwa ukubopha nokutywina iintlobo ezahlukeneyo zeglasi nezinye izinto ezisisiseko. Yahlulwe kakhulu kwiindidi ezimbini: i-silicone sealant kunye ne-polyurethane sealant (PU). I-Silicone sealant yahlulwe yaba yi-acid sealant, i-neutral sealant, i-structural sealant, njl. I-Polyurethane sealant yahlulwe yaba yi-adhesive sealant kunye ne-sealant.
Izicelo ezithile ze-glass sealant
1.Ifanelekile ukutywinwa kweendonga ezahlukeneyo zamakhethini ezingamelani nemozulu, ingakumbi ukutywinwa kweendonga zamakhethini eglasi ezingamelani nemozulu, iindonga zamakhethini eephaneli ze-aluminium-plastiki, kunye nelitye elixhonywe elomileyo.
2. Ukuvala umthungo phakathi kwesinyithi, iglasi, i-aluminium, iithayile zeseramikhi, iglasi yendalo kunye neglasi egqunyiweyo.
3. Ukuvalwa kwekhonkrithi, isamente, ukwakhiwa kwelitye, ilitye lemabula, intsimbi, umthi, i-aluminiyam eyosiweyo kunye nomphezulu we-aluminiyam opeyintiweyo. Kwiimeko ezininzi akukho mfuneko yokusebenzisa i-primer.
4. Inokumelana okuhle kakhulu nemozulu okufana nokuxhathisa i-ozone kunye nokuxhathisa i-ultraviolet, kwaye inobomi obude benkonzo.
Intshayelelo yesitywina
I-Sealant ibhekisa kwizinto zokutywina eziguqukayo ngokwemilo yomphezulu wokutywina, ezingalulanga ukuhamba, kwaye zinamandla athile okuncamathelisa. Ihlala isekelwe kwizinto ezomileyo okanye ezingomiyo ezifana ne-asphalt, i-resin yendalo okanye i-resin yokwenziwa, irabha yendalo okanye irabha yokwenziwa, ize yongeze izizalisi ezingasebenziyo, ilandelwe zii-plasticizers, izinyibilikisi, ii-curing agents, ii-accelerators, njl. Zilinde imveliso. Ii-Sealants zahlulwe ngokusebenza kwazo. Umsebenzi wazo kuphela kukutywina. I-sealant engamelani nemozulu, i-silicone structural sealant, kunye ne-polyurethane sealant zonke zinemisebenzi yokutywina, kodwa zikwanayo neminye imisebenzi ebaluleke kakhulu, njengokuqina okuphezulu kokubopha kunye nokumelana okuhle kwemozulu.
Ukusetyenziswa okuthe ngqo kwezitywini
1. Ngokwendlela yokwahlulahlula, inokwahlulwa ibe yi-building sealant, i-automobile sealant, i-insulation sealant, i-packaging sealant, i-mining sealant kunye nezinye iintlobo.
2. Ngokwendlela ezahlulwe ngayo emva kokwakhiwa, inokwahlulwa ibe yi-cried sealant kunye ne-semi-cured sealant. I-cured sealants inokwahlulwa ibe yi-rigid sealants kunye ne-flexible sealants. I-rigid sealant yinto eqinileyo eyenzeka emva kwe-vulcanization okanye i-solidification. Ayina-elasticity ingako, ayinakugoba, kwaye i-joint ayinakushukuma; i-flexible sealant iyanwebeka kwaye ithambile emva kwe-vulcanization. I-non-curing sealant yi-soft-curing sealant egcina i-tackifier yayo engomiyo kwaye iyaqhubeka nokufudukela kumphezulu emva kokusetyenziswa.
Isitywini solwakhiwo
I-structural sealant inamandla aphezulu (amandla oxinzelelo>65MPa, amandla okubopha okutsalwa kwentsimbi ukuya kwintsimbi>30MPa, amandla okusika>18MPa), inokumelana nemithwalo emikhulu, iyamelana nokwaluphala, ukudinwa, kunye nokugqwala, kwaye isebenza kakuhle ngexesha layo elilindelekileyo. I-adhesive ezinzileyo ifanelekile kwiinxalenye zesakhiwo zokubopha ezinokumelana namandla anamandla.
1. Isetyenziswa kakhulu kwizixhobo zokubopha ezakhiweyo okanye ezingezizo ezakhiweyo phakathi kwesinyithi sodonga lweglasi kunye neglasi.
2. Iglasi inokuqhagamshelwa ngqo kumphezulu wezinto zesinyithi ukuze yenze icandelo elinye lokuhlanganisa ukuze kuhlangatyezwane neemfuno zoyilo lwesakhelo esifihliweyo ngokupheleleyo okanye iindonga zekhethini zesakhelo esifihliweyo kancinci.
3. Ukubopha kunye nokutywina iglasi yokukhusela.
4. Ifanelekile ukubopha, ukugquma kunye nokuvala ilitye elinemingxuma, iglasi elaminethiweyo, iglasi yokukhusela, iglasi yesibuko, iglasi egqunywe nge-coated, i-zinc, i-copper, i-iron kunye nezinye izinto.
