Adhesives thiab sealants uas nyob rau hauv kev ua lag luam niaj hnub no muaj ntau haiv neeg thiab muaj ntau yam kev siv.
Glue yog ib yam khoom siv los txuas cov khoom sib txawv vim cov txheej txheem adhesion ntawm cov nplaum nplaum thiab ntau qhov chaw. Nws yog ib tug natural los yog hluavtaws raws li sib tov los yog tov.
Cov qauv tshuaj ntawm cov nplaum kuj txawv. Tsis tas li ntawd, lawv raug cais los ntawm kev sib xws ua kua lossis hmoov.
Raws li txoj kev gluing, lawv yog cov hauv qab no: PVA, kev sib cuag, kub yaj nplaum nplaum thiab cov uas ua haujlwm ntawm qib molecular.
Adhesives-sealants tau txais txiaj ntsig tseem ceeb. Lawv yog siv nyob rau hauv kev sib dhos ntawm cov khoom, ntau yam khoom siv, tshuab, cua tshuab, thiab lwm yam. Nrov yog cov kua nplaum-sealant "Moment", uas belongs rau hom waterproof. Nws yog siv rau kev sib txuas ntawm ntau qhov chaw - ntoo, tawv, roj hmab, iav, ceramics, thiab lwm yam. (tshwj tsis yog cov tais diav uas npaj yuav noj).
Nws yuav tsum tau muab sau tseg tias cov nplaum nplaum yog tsim los ntawm cov polymers. Feem ntau, nws muaj polysulfide, nrog rau organosilicon rubbers. Main Spectrumdaim ntawv thov - sau ntau qhov khoob thiab tawg, nrog rau kev sib khi lub qhov rooj thiab qhov rais.
Raws li cov tshuaj muaj pes tsawg leeg, cov nplaum nplaum yog acrylic, silicone thiab polyurethane. Hom Acrylic yog siv los sau cov pob qij txha thiab tsis muaj cov kab nrib pleb loj heev ntawm cov pob zeb lossis pob zeb.
Nws yuav tsum raug sau tseg tias cov nplaum acrylic tsis muaj cov kuab tshuaj, tuaj yeem siv los kaw cov kab nrib pleb me me hauv tsev thiab sab nraum zoov. Lawv yog cov yam ntxwv zoo adhesion rau pob zeb, plaster, nrog rau cov ntoo thiab cib, lawv muaj peev xwm tsim ib zaj duab xis nyob rau hauv 15 feeb thiab khaws lawv cov khoom ntawm qhov kub ntawm -25 - +80 ° C. Tsis tas li ntawd, cov nplaum nplaum nplaum nplaum nplaum nplaum no tiv taus UV rays thiab lub teeb, siv ncaj qha los ntawm lub raj lossis nrog rab phom tshwj xeeb.
Hom silicone ntawm cov nplaum no yog siv los ua cov insulators, uas pab txhim kho lub qhov rais thav duab, qhov rooj thiab ntau yam hlau, tiv thaiv kev nkag mus ntawm cov ntxhiab tsw txawv teb chaws thiab dej. Nws yog tsim nyog sau cia tias silicone nplaum-sealant yog tus cwj pwm los ntawm kev ua kom zoo rau iav, ntoo, enamel thiab ceramic nto. Nws kuj muaj qhov ua haujlwm siab rau qhov kub thiab txias thiab ntau yam huab cua.
Cov nplaum no muaj ntau yam xim lossis tsis muaj xim (pob tshab). Thaum ua ntawv thov, nws yuav tsum nco ntsoov tias qhov chaw ua haujlwm yuav tsum huv, qhuav thiab tsis muaj rog, thiab ua tiav solidification tshwm sim tsuas yog nyob rau hauv.hnub.
Polyurethane nplaum sealant yog ib qho compacted thiab nplaum loj, uas tuaj yeem tswj tau zoo elasticity rau lub sijhawm ntev. Lawv yog siv los kaw cov ntaub ntawv. Nws yuav tsum tau muab sau tseg tias polyurethane-raws li adhesives sai sai lo ua ke ob qhov chaw, ua nyuaj thaum nyob rau hauv kev sib cuag nrog dej, thiab yuav ua tau varnished los yog pleev xim rau. Kev npaj saum npoo txheej txheem (kev ntxuav thiab degreasing) yuav tsum tau ua ua ntej thov.
