Hauv ntau thaj chaw ntawm kev lag luam thiab kev tsim kho, tshwj xeeb epoxy resin tau pom dav siv. Cov khoom siv hluavtaws no, uas yog tsim los ntawm cov pab pawg sib txawv epoxy, feem ntau ua raws li cov muaj zog super thiab muaj cov nplaum zoo. Niaj hnub no peb yuav tham txog cov yam ntxwv thiab cov khoom ntawm ob-tivthaiv epoxy cob.
Peculiarities
Ob-tivthaiv epoxy resin yog oligomer tshwj xeeb uas, thaum ua ke nrog cov tawv tawv tshwj xeeb, tsim cov crosslinked polymer uas hloov pauv nws lub cev yam ntxwv. Cov tshuaj yaj yeeb no muaj cov tshuaj ua kom yooj yim dua.
Cov muaj pes tsawg leeg ntawm cov tshuaj, vim nws muaj pes tsawg leeg polymer, yog ib txoj hauv kev zoo rau kev sib koom ua ke tau zoo ntawm ntau qhov chaw ntawm qhov sib txawv sib txawv rau ib leeg
Tib lub sijhawm, nws muab kev sib txuas zoo tshaj plaws thiab ruaj khov.
Qhov sib txawv ntawm ib qho tivthaiv epoxy cob
Qhov sib txawv tseem ceeb ntawm ob hom no feem ntau yog nyob hauv cov txheej txheem kho thiab siv rau saum npoo. Ib-thooj qauv raug kho nrog dej noo los ntawm lub hauv paus thiab huab cua. Ntxiv mus, qhov nrawm ntawm cov txheej txheem no yuav vam khom feem ntau ntawm cov pa cua.
Ob-tivthaiv epoxy yuav kho los ntawm cov tshuaj tshwj xeeb cov tshuaj tiv thaiv . Nws tshwm sim nruab nrab ntawm cov khoom tseem ceeb, suav nrog cov tawv tawv.
Hauv qhov no, qhov nrawm ntawm cov txheej txheem yuav nyob ntawm qhov ntsuas kub ntawm cov khoom thiab ib puag ncig.
Sib xyaw
Cov muaj pes tsawg leeg ntawm ob-tivthaiv epoxy cob muaj cov hauv qab no:
- microspheres, nrog rau cov khoom nplua-nplua uas yog koom nrog pab pawg no;
- paj rwb thiab iav fiber ntau, tsim los muab ntau qhov ntom ntom thiab viscosity rau pawg;
- cov hmoov sib xyaw - asbestos, chalk thiab cement;
- ntoo ntoo ua los ntawm ntuj ntoo yog qhov tsim nyog txhawm rau txo qhov nqus tshwj xeeb;
- aerosil kom txo qis qhov smudges;
- xim ntxiv xim xws li graphite, titanium dioxide.
Saib
Tam sim no, muaj ntau tus qauv sib txawv ntawm cov tshuaj no. Nyob ntawm qhov sib xws, lawv tau muab faib ua ntau hom.
- Ua kua . Qhov kev xaiv no feem ntau muag hauv koob txhaj tshuaj tshwj xeeb. Cov kua ua kua yuav tsum tau maj mam muab nyem tawm ntawm lub khob thiab feem ntau tuaj nrog cov chaw xaiv tau. Cov qauv no ua rau nws muaj peev xwm lo cov khoom me me ua ke. Cov kua ua kua tsis tas yuav tsum tau npaj rau siv, lawv tuaj yeem npaj tau.
- Qab . Cov tshuaj epoxy no tau tsim ua cov yas yas, hauv lawv cov qauv lawv yuav zoo ib yam li cov yas yooj yim. Cov qauv no tuaj yeem txiav tau yooj yim nrog rab riam me me, tom qab ntawd koj yuav tsum tau txhuam nws me ntsis nrog koj txhais tes thiab moisten nws nrog dej me ntsis, tom qab ntawd cov khoom siv tau npaj rau siv. Nco ntsoov tias qhov sib xyaw ua tiav yuav tsum tuab heev. Tom qab kev npaj zaum kawg, qhov hnyav tau maj mam siv rau ntawm cov khoom.
Thaum xaiv, nco ntsoov txiav txim siab hom resin. Rau kev ua haujlwm nrog ntu me me, nws yog qhov zoo dua los xaiv qhov kev xaiv ua kua. Rau kev sib txuas ruaj khov dua ntawm cov ntaub ntawv loj, koj tuaj yeem tau txais lub ntsej muag zoo nkauj.
Cov ntawv thov
Ob-tivthaiv epoxy resin tau siv dav hauv cov haujlwm xws li kev siv tshuab, tsheb, pleev xim. Qee lub sij hawm nws tsim nyog rau txheej txheem teeb tsa, suav nrog thaum teeb tsa kev tiv thaiv dej ntawm cov pas dej da.
Cov tshuaj no tseem tuaj yeem siv hauv kev tsim khoom ntawm ntau yam khoom siv hluav taws xob, hauv kev tsim cov khoom lag luam los ntawm fiberglass lossis fiberglass.
Cov khoom siv no feem ntau yog siv los ntawm cov tsim qauv thiab tus tswv ntawm kev kos duab . Ua tsaug rau 2-tivthaiv resin, koj tuaj yeem tsim ntau yam kev dai kom zoo nkauj, cov khoom zoo nkauj ntawm cov rooj tog, khoom plig me me thiab nthuav phab ntsa moos nrog koj tus kheej tes.
