Synthetic silicone yog mos thiab pliable rau kov. Nws tau siv dav hauv aviation, aerospace, automotive, kev ua liaj ua teb, kev thauj mus los rau pej xeem, thiab kev tsim kho txij li nruab nrab ntawm lub xyoo pua 20th. Cov khoom los ntawm nws muaj ntau haiv neeg: cov raj kho mob, khau insoles, xov tooj, ci pwm thiab lwm yam.
Qhov teeb meem tshwm sim thaum nws yuav tsum tau txuas cov khoom siv. Tab sis tsis yog txhua tus paub yuav ua li cas kua nplaum silicone.
Ntse
Yam khoom ua los ntawm silicone muaj cov khoom nram qab no:
- hluav taws xob insulating;
- kub resistant;
- tiv taus hluav taws xob, hluav taws xob teb thiab tso tawm;
- inert rau kev cuam tshuam ntawm microbes;
- non-toxic;
- resistant rau deformation (cov khoom yog elastic) ntawm qhov kub thiab txias, tsis tawg.
Txawm hais tias cov khoom zoo li no, cov khoom siv kuj muaj qhov tsis zoo. Piv txwv li, cov neeg feem coob muaj teeb meem sib txuas cov khoom siv silicone thiab txuas rau lwm cov ntaub ntawv. Yog li, koj yuav tsum siv cov nplaum tshwj xeeb kom ua tiav lub zog ntawm adhesion.
Thawjkua nplaum silicone:
- Silicone nplaum nplaum.
- Cyanoacrylate nplaum.
Lawv tso cai rau koj kaw qhov sib koom ua ke, ua ke kom nruj. Cov khoom xyaw tuaj yeem siv rau hauv cov khoom sib xyaw xws li silicone-hlau, silicone-yas, silicone-rubber. Ib yam li ntawd, lawv daws cov lus nug ntawm yuav ua li cas muab cov silicone nplaum ua ke.
Pros:
- tsis muaj zog nyob ntawm qhov kub thiab txias ib puag ncig;
- ua kom tsim tau ib daim ntawv cog lus elastic nrog lub zog tensile siab.
Cons:
- ntev sijhawm;
- tuab muaj pes tsawg leeg tawm qhov sib txawv loj thaum gluing;
- muaj peev xwm txiav tawm;
Cov tebchaw no muaj lub zog txaus nrog thaj chaw sib cuag loj.
YCyanoacrylate
Pros:
- kho sai sai thiab sib raug zoo hauv vib nas this;
- muaj zog thiab yoog raws kev sib koom ua ke;
- yooj yim ntawm kev ua haujlwm thiab kev siv cov khoom sib xyaw rau cov khoom;
- seam tiv thaiv kev co thiab poob siab;
- tsis muaj cov kuab tshuaj;
- cov ntaub nplaum ntawm cov khoom sib txawv yam tsis poob lub zog;
- tiv taus qhov kub siab (txog 250 ° C).
Cons:
- koj yuav tsum tau kho qhov chaw ua ntej nrog primer kom tau txais txiaj ntsig zoo;
- chaw ua haujlwm yuav tsum tau ua pa.
Kev xaiv kua nplaum
Rau cov khoom siv silicone sab nraum zoov, yuav tsum muaj kua nplaum sab nraum zoov. Rau kev kho qhov chaw hauv tshebtxhais tau tias siv cov khoom siv tsheb tshwj xeeb. Yog tias silicone tom qab siv rau qhov kub thiab txias, yuav tsum muaj cov nplaum kub kub.
Tus neeg sawv cev polymer nrov tshaj plaws yog Klebfix, uas yog tsim los rau kev sib khi hlau, yas, roj hmab thiab lwm yam ntaub ntawv hauv ntau qhov sib txuas.
Cov khoom lag luam zoo - cyanoacrylate muaj pes tsawg leeg Permabond. Lawv tuaj yeem ua cov ntaub ntawv tsis sib xws, haum rau cov ntaub ntawv khoov. Cov nplaum tuaj yeem siv nrog cov primer ntawm tib hom.
Yuav ua li cas nplaum silicone:
- Sealant ELASTOSIL E43 German tuam txhab. Cov khoom tsis tas yuav tsum tau siv cov khoom siv nplaum, nws yog siv los txuas thiab kaw cov iav, yas, ceramics, ntoo, silicone roj hmab, hlau thiab lwm yam. Self-leveling zog.
- Glue ua nyob rau hauv lub teb chaws Yelemees REMA-VALMEXIN sc 38 kuj tsim nyog mloog. Cov khoom lag luam nrog kev siv xws li kev sib xyaw ua ke tsis ntshai dej. Ntxiv nrog rau cov khoom nplaum, nws rov kho cov khoom ua los ntawm silicone, PVC, roj hmab thiab latex.
- Glue ntawm German chaw tsim tshuaj paus Weiss COSMOFEN CA 12 txuas silicone, ceramics, roj hmab, yas thiab lwm yam ntaub ntawv. Nws tiv taus UV hluav taws xob, kub hloov pauv, dries sai sai. Cov khoom siv suav nrog ib qho khoom siv yooj yim. Qhov kev xaiv no yog tus yam ntxwv ntawm lub zog siab. Nws raug pom zoo kom kho cov khoom ua ntej nrog Cosmoplast 588 primer kom zoo dua adhesion.
Yogsiv ib qho ntawm cov kev xaiv no, ces yuav tsis muaj lus nug ntxiv txog yuav ua li cas kua nplaum silicone.
Technology ntawm kev ua haujlwm
Nws raug nquahu kom ntxuav, qhuav thiab tshem tawm cov roj ntawm cov khoom siv los ua kua nplaum. Tom qab ntawd siv cov muaj pes tsawg leeg rau lub hauv paus raws li cov lus qhia. Los ntawm txoj kev, kev nyiam yog muab rau cov kua nplaum nrog lub dispenser.
Nws yog qhov tsim nyog los tuav cov khoom rau 1-3 feeb lossis tsawg dua los ntawm kev nyeem cov chaw tsim khoom cov lus qhia kom ntxaws.
Nws tsis txaus kom paub cov kua nplaum silicone. Nws yog ib qho tseem ceeb kom ua raws li kev tiv thaiv kev nyab xeeb thaum ua haujlwm. Nws qhia txog kev ua raws li cov ntsiab lus hauv qab no:
- airing chav;
- kub rau kev ua haujlwm - tsis siab tshaj 25 degrees;
- siv cov hnab looj tes tiv thaiv thiab tsom iav.
Lub sijhawm ua haujlwm siab tshaj plaws - tsis pub dhau 20 feeb, txwv tsis pub cov khoom xyaw yuav qhuav.
