Dab tsi yog qhov zoo thiab tsis zoo ntawm polyurethane seavant?
Raws li hom sealant, polyurethan sealant yog ua los ntawm polyurethane expolymer thiab polyurethane roj hmab. Hom kev sib foob no muaj lub zog siab tensile muaj zog, cov roj tsis kam, tab sis dej tsis zoo, tshwj xeeb tshaj yog cov dej tsis zoo. Nws tuaj yeem muab faib ua peb hom: Hom cua kub volcanization, chav kub vulcanization hom thiab kub qhuav hom. Ntawm lawv, chav nyob qhov kub tau muab faib ua ib qho tivthaiv thiab ob yam. Nws yog dav siv raws li caulking sealing cov khoom hauv cov tuam tsev, plaub fab, thiab cov khoom lag luam hauv tsheb, tso pa tawm, submarines thiab rockets.
Polyurethane seavant muaj cov txiaj ntsig hauv qab no:
1. Polyurethane seavant muaj kev coj zoo tsis kam lees paub tom qab siv, uas tuaj yeem txo kev sib txug thaum siv thiab muab kev pabcuam lub neej.
2. Qhov kev ua tau zoo tuaj yeem hloov kho ntawm yuav. Yog tias tus neeg siv tsis paub meej txog kev sib npaug ntawm kev hloov kho tus kheej, xws li Cosmore Foob thiab muab cornethane formants thiab muab customized saladetant daim ntawv thov daws. Nws muaj ntau yam ntawm kev siv thiab tuaj yeem siv rau lub zog tshiab, kev kho tub rog, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, kev lag luam ceev thiab lwm yam lag luam.
3. Qhov kev pabcuam lub neej yog ntev heev, thiab kev ua yeeb yam yuav tsis hloov hauv 15 txog 20 xyoo nyob rau hauv ib puag ncig kev siv.
4. Tom qab kho tau, polyurethane sealants muaj cov roj ua tau zoo thiab muaj kev laus cov khoom, thiab tuaj yeem siv ntau hom teb.
Tsis tas li ntawd, kev so tsawg muag; dav kho tau ntau yam ntawm kev ua tau zoo; muaj zog kho tshuab; polyurethane lasalants, zoo adhesion; zoo elasticity, zoo heev rov qab, haum rau cov pob qij txha dynamic; Cov huab cua zoo tsis kam, tus nqi nruab nrab.
Polyurethane las voos tseem muaj qee qhov tsis zoo. Tsis kub-resistant rau lub sijhawm ntev; Lub teeb-xim cov qauv tsim tau yooj yim cuam tshuam los ntawm ultraviolet teeb kev laus; Cov khoom ntim ruaj khov ntawm cov kua nplaum uas sib xyaw ua ke tau yooj yim heev los ntawm kev ntim khoom thiab lub ntiaj teb sab nraud, thiab feem ntau yog kho tau qeeb; Cov npuas thiab cov kab nrib pleb yuav tshwm sim hauv cov chaw kub siab; Primer yuav tsum muaj nyob rau hauv ntau zaus. Nyob rau tib lub sijhawm, polyurethane sealant muaj cov dej tsis zoo, tshwj xeeb tshaj yog cov alkaline dej tsis kam.
