Cov khoom tseem ceeb ntawm silicone tubing yog silicone roj hmab, siab -molecular polymer tsim los ntawm cov khoom xws li silicon, oxygen, carbon, thiab hydrogen. Tsis zoo li cov roj hmab zoo tib yam, nws cov saw tseem ceeb muaj silicon -oxygen daim ntawv cog lus, uas muab nws cov khoom tshwj xeeb. Thaum lub ambient kub fluctuates drastic, xws li los ntawm sub-zero kub nyob rau hauv lub caij ntuj no mus rau pua pua degrees Celsius thaum lub sij hawm lub cav ua hauj lwm, cov kev ua ntawm cov molecular saw ntu nyob rau hauv lub silicone tubing hloov loj heev. Thaum qhov kub thiab txias, cov saw hlau molecular txav qeeb, thiab cov khoom siv ib ntus hardens, tab sis nws tsis ua nkig thiab tawg zoo li qee cov roj hmab; ntawm qhov kub thiab txias, cov saw hlau molecular txav zuj zus, thiab cov khoom tseem mos thiab zoo elastic rov qab. Qhov kev ruaj ntseg no dhau qhov kub ntawm qhov dav yog lub hauv paus rau nws txoj kev xaiv raws li cov khoom siv rau cov kav dej hauv tsheb.
Raws li cov yam ntxwv no, silicone tubing plays lub luag hauj lwm ntawm "saj zawg zog" nyob rau hauv lub cav compartment. Nws txuas cov kav hlau los yog cov yas yas, absorbs vibrations thiab displaces thaum lub cav ua haujlwm, thiab tiv taus lub siab thiab tshuaj lom neeg ib puag ncig hauv cov cua txias. Nws qhov tsis ua haujlwm feem ntau tsis yog tam sim ntawd tawg, tab sis maj mam hloov lub cev ntawm kev ua haujlwm. Ntev - lub sij hawm thermal aging tuaj yeem ua rau tsis tuaj yeem tawg lossis hla - txuas ntawm silicone molecular chains, manifesting li microcracks, hardening, los yog ntau softening ntawm cov khoom nto. Nruam thermal cycling kev nyuaj siab accelerates qhov kev nthuav tawm ntawm cov microcracks.
Los ntawm kev ua tau zoo maj mam pom, lub luag haujlwm tseem ceeb hauv kev tswj xyuas cov tubing silicone yog qhov pom kev tsis tu ncua thiab kev soj ntsuam tactile. Tsis muaj cov cuab yeej tshwj xeeb, nrog lub cav txias, tsom mus rau kev kuaj xyuas sab nrauv ntawm lub raj kom tsis txhob muaj luster, tawg, bulges, lossis qhov chaw o. Nyem lub raj los ntawm txhais tes kom hnov nws elasticity rau uniformity, thiab xyuas seb qhov chaw txawv txav los yog spongy. Tshawb xyuas cov clamps rau qhov sib sib zog nqus indentations los yog cov cim qhia ntawm to. Cov kev kuaj xyuas no yuav tsum tau ua ua ke nrog lub sijhawm saib xyuas lub tsheb, tshwj xeeb tshaj yog thaum lub caij hloov pauv thiab lub sijhawm ntawm qhov kub thiab txias.
