Qhov cuam tshuam ntawm kev mob ntawm cov viscosity thiab cov neeg kho tshuab ntawm silicone yog qhov tseem ceeb hauv qab no:
1. Cov nyhuv ntawm viscosity
Txo viscosity:Ib qho ntawm cov haujlwm tseem ceeb ntawm kev mob yog txhawm rau txo cov viscosity ntawm silicone, ua rau nws yooj yim rau lub tsho loj lossis luam tawm. Cov tshuaj ua rau zoo xws li ethanol, ethyl acetate, butanone, thiab lwm yam nplaum tau nplaum hauv silicone, yog li kho nws viscosity rau qib xav tau.
Kev tswj cov kua fws:Los ntawm kev kho cov nyiaj ntawm diluent, fluidity ntawm silicone tuaj yeem tswj tau kom tau raws li cov kev xav tau ntawm cov txheej txheem sib txawv thiab cov ntawv thov. Txawm li cas los xij, kev qaug zog ntau dhau yuav ua rau cov kua dej ntawm cov roj cua kom muaj zog, cuam tshuam rau cov qauv ntawm cov qauv luam tawm.
2. Cov nyhuv ntawm cov khoom siv khoom siv
Txo Tensile Thiab Dua Lub Zog:Qhov sib ntxiv ntawm kev ua kom tsis muaj zog ntawm cov zog sib xyaw ntawm silicone, uas ua rau muaj kev txo qis hauv lub zog thiab rhuav lub zog nrog ntxiv. Qhov kev cuam tshuam no cuam tshuam tau ncaj qha rau kev txo qis hauv kev txo qis hauv qhov chaw qis vim tias cov neeg raug tshem tawm cov kev sib piv ntawm tus ntoo khaub lig polymer.
Cuam tshuam Hardness:Qhov sib ntxiv ntawm ib tug lej ntawm kev rau siab yuav txo qhov tawv ntawm silicone tom qab kho tau. Piv txwv li, thaum roj silicone siv los ua cov roj silicone siv, lub hardness ntawm cov kua silicone tom qab kho tau los ntawm 1 degree rau txhua 2% ntawm cov roj silicone ntxiv. Qhov kev hloov pauv no hauv kev puas tsuaj yuav cuam tshuam qhov kev siv ntawm silicone hauv cov ntawv thov tshwj xeeb.
Tej zaum yuav muaj kev pheej hmoo ntawm cov khoom siv tshuab ua puas tsuaj:Yog hais tias tus nqi ntawm diluent tsis tsim nyog, nws yuav ncaj ncaj rau cov khoom tseem ceeb ntawm cov roj hmab silicone, xws li tensile modulus. Piv txwv li, hauv RTV silicone roj hmab system, ntau dhau ntawm kev ua kom hnyav, ω-dhiroxy polydimethylsiloxane los yog methyl Silicone roj yuav ua rau muaj kev txo qis hauv cov tshuab tshuab.
