Nyob rau hauv kev tsim cov polyurethane muag daim txhuam cev ua npuas ncauj, cov roj uas cov roj silicone feem ntau nyob ntawm nws viscosity thiab application scenario.
Viscosity xaiv ntawm Silicone Roj
Tsis muaj viscosity roj silicone roj: hauv zus tau los ntawm cov polyurethane mos mos daim txhuam cev, qis viscosity Dhuav, roj qis yog siv. Qhov no roj silicone muaj roj zoo heev, cov kub ua tsis taus thiab cov tshuaj lom tsawg. Nws tuaj yeem tsim cov yeeb yaj kiab nyias nyias nyob saum npoo ntawm daim txhuam cev, uas yog kev tiv thaiv ua npuas dej, thaum txhim kho cov ris kev tiv thaiv, cov dej kub tsis kam thiab ua kom sov ntawm daim txhuam cev.
Siab viscosity Silicone roj: rau cov txheej txheem sponges thiab roj hmab sponges, nws yog qhov haum ntau los xaiv siab viscosity roj. Qhov no yog vim hais tias cov kab ntawv no muaj qhov loj sab hauv qab, thiab cov roj viscosity siab silicone tuaj yeem tsim cov khoom lag luam tiv thaiv thiab corrosion tsis kam thiab corrosion tsis kam thiab corrosion tsis kam ntawm daim txhuam cev.
Lub Luag Hauj Lwm Ntawm Silicone Roj Hauv Zus Tau Tej Cov Polyurethane Muag Ua Npuas Ncauj
Silicone roj ua lub luag haujlwm tseem ceeb hauv kev tsim cov polyurethane muag daim txhuam cev. Nws tsis tsuas yog ua kom cov kev pabcuam lub neej ntawm daim txhuam cev, tab sis kuj tseem txhim kho cov khoom ntawm lub cev ntawm daim txhuam cev. Silicone roj tau ntxiv ntawm cov ntaub ntawv kaw lus thiab nthuav dav los ntawm kev thov, txau lossis sib xyaw, thiab yog kom nkag rau sab hauv ntawm daim txhuam cev. Tsis tas li ntawd, Silicone roj yuav tsum tau siv nrog lwm cov kev sib ntxiv xws li whaseners, fillers, defoamers, thiab lwm yam kom ua tiav cov txiaj ntsig zoo dua.
Hom thiab cov yam ntxwv ntawm cov roj silicone
Polyurethane Silicone Roj yog cov duab sib dhos polymer Nws cov qauv molecular muaj cov pab pawg nquag xws li amino, Hydroxyl, Ethere Bond thiab siloxane muab nws ua rau nws ua tau zoo. Polyurethane Silicone Roj muaj cov muag muag zoo thiab elasticity, uas tuaj yeem txhim kho kev nplij siab thiab kev ua tau zoo ntawm cov khoom; Nyob rau tib lub sijhawm, nws muaj huab cua zoo tsis kam thiab tshuaj lom neeg tiv thaiv, thiab tuaj yeem tiv taus kev sim ntawm ntau yam ib puag ncig.
